PROTOCOL SYNOPSIS

Title: An Extension Study to Evaluate 24 Months of Standard-of-Care Osteoporosis Management Following Completion of 18 Months of BA058 or Placebo Treatment in Protocol BA058-05-003

Protocol Number: BA058-05-005

Test Drug: Alendronate

Study Objectives:

Please note that the name of BA058 Injection 80 µg has been changed to Abaloparatide-SC, therefore the name has been changed throughout the document.

The primary objective of this study is to collect clinical information regarding six months of treatment with alendronate, in subjects who have previously received 18 months of blinded treatment with Abaloparatide-SC or Placebo in Study BA058-05-003. Safety data will be obtained via clinical, laboratory and radiologic assessments. Following the initial six months of treatment in the study, subjects will then enter the long-term observational phase of the study during which subjects will continue to receive alendronate treatment for an additional 18 months (for a total of 24 months).

The specific objectives of this study are to:

· Provide additional information on safety in study subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide information on the vertebral fracture rate in subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on non-vertebral fractures and BMD change associated with six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on BMD change and osteoporosis status associated with 24 months of treatment with alendronate after 18 months of treatment with Abaloparatide-SC/Placebo.

The analysis performed at six months of this Extension Study will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. Vertebral fractures based on radiologic assessments will also be analyzed at Month 24. Additional analyses for other endpoints will be conducted cumulatively at Months 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of the statistical procedures to be used will be provided in the Statistical Analysis Plan.

Study Population:

Subjects with postmenopausal osteoporosis who completed the End-of-Treatment Visit (Visit 9) for Study BA058-05-003 and were previously randomized to either blinded Abaloparatide-SC or blinded Placebo are eligible for inclusion into this Extension Study provided that they fulfill the Inclusion/Exclusion criteria described below.

Inclusion/Exclusion Criteria

Otherwise healthy ambulatory postmenopausal women who participated in, and who completed 18 months of treatment with either blinded Abaloparatide-SC or blinded Placebo in Study BA058-05-003, are scheduled to complete or have completed the End-of-Treatment visit (Visit 9 in Study BA058-05-003), and who have provided a new written informed consent for the Extension Study, are eligible for enrollment into this study. Participants must be no more than 40 days from Visit 9 in Study BA058-05-003 to be eligible for this study. The physical examinations and clinical laboratory

measurements from the End-of-Treatment visit from Protocol BA058-05-003 (Visit 9) of the BA058-05-003 study will provide baseline data for this Extension Study. In addition, the subjects must, in the opinion of the Investigator, be appropriate candidates for treatment with alendronate.

Subjects will not be enrolled if they experienced a treatment-related SAE as assessed by the Investigator, or if they were withdrawn from Study BA058-05-003 for any reason. Specific inclusion and exclusion criteria are described in Section 4.1 and Section 4.2, respectively.

Study Design and Methodology:

Number of Subjects

All subjects who were randomized to the Abaloparatide-SC/Placebo arms in Study BA058-05-003, and who completed 18 months of treatment will be offered the opportunity to participate in this study. There will, therefore, be a potential maximum of 1,600 subjects eligible to be enrolled in this study.

Design

This study will be an open-label extension of Study BA058-05-003. The purpose of the study is to provide longer term safety data, fracture data and BMD data after treatment with alendronate, in otherwise healthy ambulatory postmenopausal women with severe osteoporosis who have previously received 18 months of blinded treatment with Abaloparatide-SC or Placebo. The analysis performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. In addition, this study will examine changes in osteoporosis status after 12, 18, and 24 months of treatment with alendronate in otherwise healthy ambulatory women with severe osteoporosis who have previously received 18 months of blinded treatment with Abaloparatide-SC/Placebo.

Subjects randomized to Abaloparatide-SC/Placebo in Study BA058-05-003 and who are candidates for alendronate treatment, will receive six months of treatment with oral alendronate at a total dose of 70 mg once per week. Following the initial six months of treatment in the study, subjects will then enter the long-term observational phase of the study during which subjects will continue to receive alendronate treatment for an additional 18 months (for a total of 24 months). All subjects will undergo protocol specified procedures (Section 7.0, Appendix 14.1 and 14.2) including BMD and fracture assessment. The study design is presented in Figure 1, below.

Figure 1: Protocol BA058-05-005 Study Design

In this study, the Follow-up Visit from the 18 month study (Visit 10 from Study BA058-05-003) will serve as the Day 1 Visit (Visit 1) for this six month Extension Study (Study BA058-05-005).

Following the initial six months of treatment, subjects will enter the long-term observational phase of this study during which the subjects will continue to receive alendronate treatment for an additional 18 months. During the long-term follow-up of this study, subjects will continue to undergo study related procedures as outlined in Section 14.1 and Section 14.2.

All subjects will continue to take calcium and vitamin D supplementation throughout the Extension Study.

Study Visits

At the End-of-Treatment Visit (Visit 9) for Study BA058-05-003, the possibility of participating in the Extension Study will be discussed with subjects randomized to Abaloparatide-SC/Placebo. This Extension Study will be comprised of 24 months of treatment with alendronate. In the month between Visit 9 and Visit 10 (between months 18 and 19 of Study BA058-05-003), the Investigator will consider the results of the assessments performed at Visit 9, including a local review of BMD, and determine if alendronate is appropriate for the subject, as part of this Extension Study.

At the Follow-up (Visit 10 for Protocol BA058-05-003, Day 1 for Protocol BA058-05-005) subjects; who were randomized to Abaloparatide-SC/Placebo, who fulfill the inclusion/exclusion criteria (Section 4.1 and Section 4.2), and who have agreed to participate in the Extension Study; will sign the Informed Consent Form and be enrolled in the study.

Subjects who have been determined by the Investigator to be candidates for alendronate therapy will receive open-label oral alendronate treatment at a total dose of 70 mg once per week for 24 months. Subjects will be instructed to take their first dose of alendronate for Study BA058-05-005 in the morning, within a week of their Day 1 visit. Following the initial six months of treatment in this study, subjects will enter the long-term observational phase of this study, during which subjects will continue to receive alendronate treatment for an additional 18 months.

All subjects will have clinic visits for study related procedures at Day 1, Month 3, Month 6, Month 12, Month 18 and Month 24. For the purpose of this study one month is equal to 30 days.

Statistical Considerations:

The statistical analyses will assess longer term safety, fracture incidence (including vertebral and non-vertebral fracture), and BMD change following treatment with alendronate for six months after the completion of a subject’s participation of 18 months in study BA058-05-003.

The efficacy and safety analyses performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. At this time-point, subjects will be analyzed based on the randomization assignment in the BA058-05-003 study.

Fractures and BMD Analyses

All specified endpoints will be summarized by treatment group and study period using standard descriptive statistics (n, mean, SD, median, minimum, maximum or n and %, as appropriate). The fracture incidence; either clinically or radiologically determined, based on clinical events or protocol-directed vertebral x-rays at Month 6 of this Extension Study; will be analyzed. In addition, BMD results from the six months of treatment with alendronate will also be analyzed based on the treatment arm they were randomized to in the BA058-05-003 study. These analyses will be conducted on all subjects with baseline and post-baseline data.

In addition to the 6-month assessment, vertebral fractures based on radiologic assessments will also be analyzed at Month 24. Additional analyses for the other endpoints will be cumulatively at Months 12, 18 and 24 (i.e., Visits 4, 5 and 6). Full details of these analyses will be provided in the Statistical Analysis Plan.

Safety Analysis

Data will be summarized and tabulated based on the enrolled population for this Extension Study. All subjects enrolled in the Extension Study will be included in the safety analysis that will be performed on the following parameters:

· Incidence and severity of AEs.

· Pathological changes in hematology, chemistry and urinalysis data based on normal ranges supplied by the clinical laboratory, if applicable.

Safety assessments for changes in physical examination, xxxxx xxxxx, ECG, and laboratory tests will be descriptively summarized by treatment and study periods. Concomitant medication classes will be categorized using World Health Organization (WHO) drug dictionary and summarized by number and percent of subjects using each class by treatment group. All treatment emergent adverse events (TEAEs) will be coded for system organ class (SOC) and preferred term (PT) using MedDRA and the number (%) of subjects experiencing each AE (SOC/PT) will be summarized by treatment, relationship to treatment, and severity. All serious adverse events (SAE) will be listed and the number (%) of subjects with an SAE presented by treatment group.

Similar safety analyses will be conducted cumulatively at Months 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of these analyses will be provided in the Statistical Analysis Plan.

Procedures and Assessments

Fractures and BMD

The End-of-Treatment (Visit 9) evaluations for vertebral fracture assessment, non-vertebral fracture assessment and BMD from Study BA058-05-003 will serve as the baseline evaluations in this study. The Day 1 assessment will be concurrent with the Follow-up Visit (Visit 10) for Study BA058-05-003. Subjects will return to the clinic for assessment of BMD at spine, hip and wrist (for those subjects who had wrist DXAs performed in Study BA058-05-003) at Month 6, Month 12, Month 18, and at Month 24. Any patient who shows a continuing significant deterioration (>7%) of BMD at

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

spine or hip from the Day 1 assessment of Study BA058-05-005 will have the assessment repeated and, if confirmed, will be discontinued from the study. Clinical and radiographic assessments for fractures will be performed at Month 6 and Month 24, and bone marker assessments of anabolism (PINP, bone-specific alkaline phosphatase and osteocalcin) and resorption (CTX) will be performed at Day 1 and Months 6, 12, 18 and 24.

Safety

Safety evaluations performed will include physical examinations, xxxxx xxxxx, 12-lead ECGs, clinical laboratory tests, and monitoring and recording of adverse events.

Complete details of the study assessments are provided in Section 7.0, in the Schedule of Visits and Procedures (Appendix 14.1) and in the Suggested Schedule of Events and Procedures by Study Visit (Appendix 14.2).

Treatments Administered

Alendronate sodium (Fosamax®, Merck & Co., Inc., or other approved generic manufacturer) 70 mg tablets for oral administration contain 91.35 mg of alendronate monosodium salt trihydrate which is the molar equivalent of 70 mg free acid and excipients. Alendronate should be stored in a well-closed container at room temperature, 15-30ºC. The alendronate may be generic substitutable approved versions which contain different inactive ingredients, but the amount of active free alendronate must be equivalent to 70 mg. Alendronate for Europe, Hong Kong and the US will be sourced centrally; alendronate for South America will be sourced locally by the medical center and reimbursed by the Sponsor. However, alendronate may be locally sourced in all venues when centrally supplied alendronate is unavailable due to unforeseen delays. The local source will be documented in the study drug logs.

Calcium (500—1000 mg) and vitamin D (400—800 IU) supplements will be sourced locally by the medical center and provided to the subjects at the expense of the Sponsor. Subjects will continue to take calcium and vitamin D as they did in Study BA058-05-003.

Duration of Subject Participation:

Participation in the initial phase of this study will be approximately six months from enrollment to completion of the six month study evaluations. Participation for both the initial and observational phases of the study will be approximately 24 months. In combination with Study BA058-05-003, subjects will participate in this clinical postmenopausal osteoporosis program for 43 to 44 months. The first visit of Study BA058-05-005 will be concurrent with Visit 10 of Study BA058-05-003.

1.0 INTRODUCTION

1.1 Background Information

Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue which leads to enhanced fragility and increased risk of fractures (Rizzoli, 2001). It is estimated that over 200 million people worldwide have osteoporosis (Reginster, 2006) and osteoporosis causes more than 8.9 million fractures worldwide, of which more than 4.5 million occur in the Americas and Europe (WHO Scientific Group, 2007). The vast majority of osteoporotic fractures occur in elderly women and incidence increases markedly with age. Most fractures occur at the spine, wrist and hip. Of these, hip fractures carry the highest morbidity and mortality. In 1990, the total number of hip fractures in men and women was estimated to be 1.26 million worldwide, and it is estimated that this number will increase to 3.6 million by 2025 and to 4.5 million by 2050 (Gullberg, 1997).

Subjects enrolled in this Extension Study will have completed 18 months of treatment with Abaloparatide-SC/Placebo. Abaloparatide is a synthetic 34 amino acid analog of parathyroid hormone related peptide(PTHrP), with molecular modifications of specific amino acids, and is under clinical development for the prevention of fractures in postmenopausal women with severe osteoporosis who are at a risk for fracture. Abaloparatide shows particular potential for reversing bone loss at both the spine and the hip, the site of the most debilitating osteoporotic fractures in elderly women. Abaloparatide is a synthetic analog of PTHrP (1-34) designed to give a greater anabolic effect than human parathyroid hormone (hPTH). Initial in vitro and in vivo studies identified abaloparatide as displaying bone anabolic properties without a significant hypercalcemic effect. In humans, abaloparatide has different pharmacokinetics (PK) and pharmacodynamics (PD) properties than hPTH(1-34) and has been shown in a Phase 2 study (BA058-05-002) to have similar or greater efficacy in restoring bone mineral density (BMD) in individuals with osteoporosis than hPTH(1-34). Overall, abaloparatide has been well tolerated in previous studies.

This is an open-label extension of Study BA058-05-003. Enrollment requires previous participation in, and successful completion of, 18 months of treatment with Abaloparatide-SC/Placebo in Study BA058-05-003. The purpose of this extension is to accumulate longer-term safety, fracture, and BMD data in subjects who receive six months of treatment with alendronate, following 18 months of treatment with blinded Abaloparatide-SC/Placebo treatment. Following the initial six months of treatment in this study, subjects will then enter the long-term observational phase of this study during which the subjects will continue to receive alendronate treatment for an additional 18 months. The analyses performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. Additional analyses will be cumulatively at Months 12, 18, and 24 (i.e., Visits 4, 5, and 6. Full details of the statistical procedures to be used will be provided in the Statistical Analysis Plan. Alendronate, a bisphosphonate, is approved and marketed world-wide for the treatment and prevention of osteoporosis in postmenopausal women.

1.2 Drug Under Study

1.2.1 Efficacy of Alendronate

Alendronate is a bisphosphonate that acts as a specific inhibitor of osteoclast-mediated bone resorption. Bisphosphonates are synthetic analogs of pyrophosphate that bind to the

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

hydroxyapatite found in bone. At the cellular level, alendronate shows preferential localization to sites of bone resorption, specifically under osteoclasts. The osteoclasts adhere normally to the bone surface but lack the ruffled border that is indicative of active resorption. Alendronate does not interfere with osteoclast recruitment or attachment, but it does inhibit osteoclast activity. (Fosamax Package Insert)

Bisphosphonates including alendronate are widely used to treat osteoporosis. In animal models, minipigs treated with alendronate exhibited a direct correlation between cancellous bone volume and bone strength (Lefage 1995). In primates, treatment with alendronate increased the strength of cancellous bone between 44 and 100% (the effect was dose dependent) when compared to vehicle, and also increased bone mass (Balena 1993). In dogs, this increase in bone mass occurred without causing abnormalities in bone modeling of bone structure (Balena, 1996).

In postmenopausal women, alendronate has been demonstrated to increase bone mineral density, decrease bone turnover and reduce the risk of fracture among women with osteoporosis (Tucci, 1996; Devogelaer, 1996; Xxxxxxxx, 1995). The therapeutic effects on bone density, remodeling and fracture prevention persist following daily treatment at an oral dose of 10 mg for up to 10 years (Bone, 2004). Studies have demonstrated that sequential treatment of osteoporosis with one year of treatment with PTH followed by one year of treatment with alendronate resulted in an increase in vertebral bone density that was considerably greater than previously reported for alendronate alone (Xxxxxxxxxx, 2000). In subjects receiving PTH(1-84) followed by alendronate, there were significant increases in BMD, in particular trabecular spine, when compared to PTH(1-84) followed by placebo (31% vs. 14%, p<0.001) (Black, 2005).

1.2.2 Safety of Alendronate Sodium

According to the US package insert for Fosamax® (alendronate sodium), in studies of up to five years duration, adverse experiences usually were mild and generally did not require discontinuation of therapy. In a three-year, placebo-controlled, double blind study in which 196 subjects were treated with 10 mg/day, discontinuation due to any adverse experience occurred in 4.1% of subjects treated with alendronate, and 6% of 397 subjects treated with placebo. The most frequently reported adverse event (occurring in >2% of subjects treated with alendronate) in this study were abdominal pain, musculoskeletal pain, nausea, dyspepsia, constipation, diarrhea, flatulence, headache and acid regurgitation.

Alendronate may cause local irritation of the upper gastrointestinal mucosa. Esophageal adverse experiences, such as esophagitis, esophageal ulcers and esophageal erosions occasionally with bleeding and rarely followed by esophageal stricture or perforation have been reported. Osteonecrosis of the jaw (ONJ), which can occur spontaneously, is generally associated with tooth extraction and/or local infection with delayed healing, has been reported in subjects taking alendronate. For subjects requiring dental procedures, discontinuation of alendronate therapy may reduce the risk for ONJ.

Atypical, low-energy, or low trauma fractures of the femoral shaft have been reported in bisphosphonate-treated patients. These fractures can occur anywhere in the femoral shaft from just below the lesser trochanter to above the supracondylar flare and are transverse or short oblique in orientation without evidence of comminution. Causality has not been

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Confidential

established as these fractures also occur in osteoporotic patients who have not been treated with bisphosphonates.

Atypical femur fractures most commonly occur with minimal or no trauma to the affected area. They may be bilateral and many patients report prodromal pain in the affected area, usually presenting as dull, aching thigh pain, weeks to months before a complete fracture occurs. A number of reports note that patients were also receiving treatment with glucocorticoids (e.g. prednisone) at the time of fracture.

Any patient with a history of bisphosphonate exposure who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Patients presenting with an atypical fracture should also be assessed for symptoms and signs of fracture in the contralateral limb. Interruption of bisphosphonate therapy should be considered, pending a risk/benefit assessment, on an individual basis.

According to the Summary of Product Characteristics for alendronate from the EMA, the following adverse experiences have been reported in alendronate treated subject during clinical trials and/or post-marketing use:

Common: Headache, abdominal pain, dyspepsia, constipation, diarrhea, flatulence, esophageal ulcer, dysphagia, abdominal distension, acid regurgitation and musculoskeletal pain.

Uncommon: Nausea, vomiting, gastritis, esophagitis, esophageal erosions, melena, rash, pruritus and erythema.

Rare: Hypersensitivity reactions including urticarial and angioedema, symptomatic hypocalcemia (often in association with predisposing conditions), uveitis, scleritis, episcleritis, esophageal stricture, oropharyngeal ulceration, upper gastrointestinal perforations, ulcers and bleeds (PUBs), rash with photosensitivity, osteonecrosis of the jaw, atypical subtrochanteric and diaphyseal femoral fractures and transient symptoms as in an acute-phase response (myalgia, malaise and rarely, fever), typically associated with initiation of treatment.

1.3 Study Rationale and Selection of Doses

1.3.1 Study Rationale

The purpose of the study is to provide longer term safety data, fracture data and BMD data after six months of treatment with alendronate, in otherwise healthy ambulatory postmenopausal women with severe osteoporosis who have previously received 18 months of blinded treatment with Abaloparatide-SC or Placebo. Following the initial six months of treatment in this study, subjects will enter the long-term observational phase of the study during which the subjects will continue to receive alendronate for an additional 18 months.

1.3.2 Study Design

Subjects randomized to Abaloparatide-SC/Placebo, who have completed 18 months of treatment in Protocol BA058-05-003 and, who meet the Inclusion/Exclusion criteria (Sections 4.2 and 4.3) are eligible to participate in this study. Subjects originally randomized to Abaloparatide-SC/Placebo in Study BA058-05-003 and who are candidates for ongoing

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

osteoporosis care, will receive 24 months of weekly open-label alendronate treatment at a dose of 70 mg/week.

1.3.3 Study Population

The study population in this protocol is comprised of otherwise healthy ambulatory postmenopausal women who:

1. have participated in Study BA058-05-003,

2. were randomized to either Abaloparatide/Placebo,

3. have completed the End-of-Treatment Visit (Visit 9 in Study BA058-05-003), and

4. have provided a new written informed consent for this protocol.

Subjects will not be enrolled if they experienced treatment-related SAE or were withdrawn from Study BA058-05-003 for any reason.

1.3.4 Selection of Endpoints

The fracture incidence; either clinically or radiologically determined, based on clinical events or protocol-directed vertebral x-rays at Month 6 of this Extension Study; will be analyzed. In addition, BMD results from the six months of treatment with alendronate will also be analyzed. Bone formation (PINP, osteocalcin, BSAP) and resorption (CTX) markers will also be assessed. Clinical incidence of any fracture and radiologic incidence of vertebral fracture will also be evaluated at Month 24. The End-of-Treatment (Visit 9) evaluations for BMD, vertebral fracture, and non-vertebral fracture assessments from BA058-05-003 will serve as the baseline evaluations in this study.

In addition to the 6-month assessment, clinical and radiologic assessment of the spine for assessment of fractures will be performed at Month 24. At Months 6, 12, 18 and 24, BMD by DXA, as well as clinical assessments of fractures will be performed. Bone formation and resorption markers will also be assessed at Day 1 and Months 6, 12 18 and 24. Further details of these assessments are in Section 7.0, and in Appendix 14.1 and 14.2.

Subjects will be monitored for safety events and will have safety assessments performed at each study visit.

1.3.5 Selection of Dose

The dose of alendronate (70 mg per week, oral) selected for this study is based upon the recommended daily dose in the product’s prescribing information.

All enrolled subjects will also continue to receive calcium (500-1000 mg) and vitamin D (400-800 IU) supplementation.

2.0 STUDY OBJECTIVES

The primary objective of this study is to evaluate data obtained following six months of treatment with alendronate, in subjects who have previously received 18 months of blinded Abaloparatide -SC/Placebo. Safety will be evaluated with clinical, laboratory and radiologic assessment. The analysis at six months will be based on the treatment that subjects were randomized to in the BA058-05-003 study. Following the initial six months of treatment in this study, subjects will then enter the long-term observational phase of the study during

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

which the subjects will continue to receive alendronate treatment for an additional 18 months.

The specific objectives of this study are to:

· Provide additional information on safety in study subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide information on the vertebral fracture rate in subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on non-vertebral fractures and BMD change associated with six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on BMD change and osteoporosis status associated with 24 months of treatment with alendronate after 18 months of Abaloparatide-SC/Placebo.

The analysis performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. Vertebral fractures based on radiologic assessments will also be analyzed at Month 24. Additional analyses for other endpoints will be conducted cumulatively at Months 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of the statistical procedures to be used will be provided in the Statistical Analysis Plan.

3.0 INVESTIGATIONAL PLAN

3.1 Overall Design and Study Plan

This study is an open-label extension of Study BA058-05-003. Subjects and Investigators who participate in Study BA058-05-005 will remain blinded to prior treatment assignment as part of BA058-05-003. At the End-of-Treatment visit (Visit 9) for Study BA058-05-003, the possibility of participating in the Extension Study will be discussed with subjects randomized to Abaloparatide-SC/Placebo. The Extension Study will be comprised of an initial six months of treatment with alendronate. In the month between Visit 9 and Visit 10, the Investigator will review the results of the assessments performed at Visit 9, including a local interpretation of BMD, and determine if alendronate is appropriate for the subject. All subjects will continue to receive vitamin D and calcium supplementation as they did in Study BA058-05-003. The study design is presented in Figure 2, below.

Participation for both the initial and observational phases of the will be approximately 24 months. There are a total of six clinic visits during the course of the study.

A brief summary of the study is provided below. For a summary of the study assessments to be performed, refer to Section 7.0 (Study Assessments) and to the Schedule of Visits and Procedures (Appendix 14.1). A more detailed description of the study procedures on a by-visit basis is provided in Appendix 14.2 (Suggested Schedule of Events and Procedures by Study Visit). A suggested order of procedures is also provided in this schedule.

3.1.1 Treatment Period

Subjects will enter into Study BA058-05-005 on Day 1, and Day 1 will also serve as Visit 10 (the Follow-up Visit) for Study BA058-05-003. The Informed Consent must be signed prior to undergoing any BA058-05-005 study related procedures, and may be signed at either Visit 9 or Visit 10 of Study BA058-05-003. Subjects who received Abaloparatide-SC/Placebo in Study BA058-05-003 will receive six months of open-label oral alendronate treatment as part of this study (BA058-05-005). Following the initial six months of treatment in this study, subjects will then enter the long-term observational phase of this study during which the subjects will continue to receive alendronate care for an additional 18 months.

If determined by the Investigator to be appropriate, treatment will be by oral administration of alendronate at a total dose of 70 mg once per week. Subjects will be given a weekly diary card to record missed doses of medication including calcium and vitamin D.

A total of six clinic visits are scheduled during the study (Day 1, Month 3, Month 6, Month 12, Month 18 and Month 24).

Subjects will be instructed to take their first dose of study drug for Study BA058-05-005 in the morning, within a week of their Day 1 visit (Day 2 of this study). Study subjects will

continue calcium and vitamin D supplementation during this study as was administered during BA058-05-003 (Section 6.1).

At Month 3, subjects will return to the clinic for medication resupply, subject diary review and questioning as to their use of concomitant medications and the occurrence of adverse events.

At the Month 6 visit ECG, and safety labs will be performed. Vertebral fractures will be determined clinically and via protocol directed x-ray evaluation; non-vertebral fractures will be determined clinically. In addition, subjects will undergo a DXA of the hip and spine (and wrist, if the subject was enrolled in the wrist DXA sub-study in Study BA058-05-003), and have samples drawn for bone markers and anti-abaloparatide antibodies. Procedures are to be performed as described in Section 7.0, Appendix 14.1 and Appendix 14.2.

At Months 12 and 18, subjects will return to the clinic for safety labs, DXA of the hip and spine (and wrist, if the subject was enrolled in the wrist DXA sub-study in Study BA058-05-003), medication resupply, subject diary review and questioning as to their use of concomitant medications and occurrence of adverse events. Serum samples for bone markers will also be drawn.

At Month 24, subjects will return to the clinic for safety labs, and will undergo clinical and radiologic fracture assessments and have DXA of the hip and spine (and wrist, if the subject was enrolled in the wrist DXA sub-study in Study BA058-05-003). Serum samples for bone markers will also be drawn. Any adverse event or clinical laboratory abnormality recorded at the Month 24 Visit will be monitored until it has resolved, become chronic or stable.

4.0 SELECTION OF STUDY POPULATION

4.1 Number of Subjects

Subjects who completed 18 months of treatment with either Abaloparatide-SC/Placebo in Study BA058-05-003 will be given the opportunity to participate in the Extension Study at all participating centers.

4.4 Withdrawal of Subjects from the Study

Subjects will be informed that they have the right to withdraw from the study at any time for any reason without prejudice to their medical care.

Consistent with the prior protocol, BA058-05-003, the Investigator must withdraw subjects from the study prior at any time in the study for the following reasons:

· Continuing significant deterioration from the Day 1 assessment of Study BA058-05-005 (>7%) of BMD at spine or hip (after confirmation of the finding);

· Treatment-related SAEs;

· Refusal of treatment;

· Refusal or inability to complete study procedures;

· Lost to follow-up.

The Investigator should exercise his/her best judgment and also has the right to withdraw subjects from the study during the study for any of the following reasons:

· ECOG Grade 3 or 4 adverse events [Refer to Appendix14.3];

· A complex of adverse events which, in the judgment of the Investigator justifies treatment cessation;

· Serious intercurrent illness;

· Non-compliance;

· Protocol violations;

· Administrative reasons.

If a subject is withdrawn or discontinued from the study, the reason for withdrawal is to be recorded in the source documents and on the case report form. All subjects withdrawn prior to completing the study should be encouraged to complete the Month 6 or Month 24 Visit (depending on the length of time on study) including any outstanding radiologic assessment or BMD assessment by DXA.

4.5 Temporary Suspension of Treatment

The Investigator has the right to suspend treatment with alendronate without withdrawal of the subject from the study. Reasons for temporary suspension of treatment may include a medical reason unrelated to an adverse event (e.g., a planned procedure), or important social or administrative events. The reason for the suspension of treatment is to be documented in the electronic case report form (eCRF) and in source documents.

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

When treatment with alendronate is restarted, the subject should resume treatment with the next scheduled dose (as if treatment had not been interrupted).

4.6 Replacement of Subjects

Subjects who have been enrolled into the study and subsequently withdraw or drop out of the study will not be replaced.

5.0 STUDY TREATMENTS

5.1 Study Medications

Alendronate will be sourced locally. Calcium and vitamin D will be provided by the study centers, similar to their provision in Study BA058-05-003.

5.1.1 Alendronate

Alendronate will be sourced centrally for Europe, Hong Kong and the US, and will be sourced locally for South America at the expense of the Sponsor. However, alendronate may be locally sourced in all venues when centrally supplied alendronate is unavailable due to unforeseen delays. The local source will be documented in the study drug logs.

Subjects will receive oral alendronate at a dose of 70 mg once per week beginning on Day 2 for 24 months. Additional provisions for dosing of alendronate should be followed based on the prescribing information. Alendronate provided will be in the approved, marketed formulation. The alendronate may be generic substitutable approved versions which contain different inactive ingredients, but the amount of active free alendronate must be equivalent to 70 mg per week.

5.1.1.1 Restrictions on Alendronate Use

Subjects should not receive alendronate if they have the following conditions/limitations:

· Abnormalities of the esophagus and other factors which delay esophageal emptying such as stricture or achalasia.

· Inability to stand or sit upright for at least 30 minutes.

· Hypocalcemia.

· Known history of hypersensitivity to alendronate, alendronate excipients, or related compounds.

5.1.2 Calcium and Vitamin D Supplements

Calcium and vitamin D supplements will be sourced locally and provided by the sites at the expense of the Sponsor.

5.2 Packaging, Labeling and Storage

Centrally supplied alendronate will not be repackaged for the study, but will be over-labeled according to local regulatory requirements as necessary.

Calcium and vitamin D supplements will not be relabeled for the study.

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Confidential

5.2.1 Storage

Alendronate must be kept in a secure, limited-access storage area until dispensed for use to a study subject. Alendronate sodium should be stored in the container provided at room temperature, 15-30ºC (59-86ºF).

Calcium and vitamin D supplements may be stored at room temperature.

5.3 Treatment Assignment

All subjects who participate will continue to be identified by the same 7-digit subject number that was assigned upon enrollment into Study BA058-05-003 throughout the study and on the eCRF.

5.4 Study Medication Administration

5.4.1 Alendronate Administration

Alendronate must be taken with water only (not mineral water) at least 30 minutes before the first food, beverage or medicinal product (including antacids, calcium supplements and vitamins) of the day. Other beverages (including mineral water), food and some medicinal products are likely to reduce the absorption of alendronate.

The following instructions should be followed exactly in order to minimize the risk of esophageal irritation and related adverse reactions.

· Alendronate should only be swallowed after getting up for the day with a full glass of water (not less than 200 mL or 7 fl. oz.).

· Subjects should only swallow alendronate whole. Subjects should not crush or chew the tablet or allow the tablet to dissolve in their mouths because of a potential for oropharyngeal ulceration.

· Subjects should not lie down until after their first food of the day.

· Subjects should not lie down for at least 30 minutes after taking alendronate.

· Alendronate should not be taken at bedtime or before arising for the day.

At the Month 3, Month 6, Month 12 and Month 18 visits, the unused alendronate tablets are to be returned to the clinic for counting and the subject will be dispensed additional alendronate. At the Month 24 visit, all unused alendronate tablets are to be returned to the study site.

5.5 Treatment Compliance

The study site personnel will perform drug accountability at each clinic visit and review each subject diary (refer to Section 7.1.16). Accountability will be documented on the appropriate forms and subjects will be re-trained on administration as appropriate. All doses of study medication are to be self-administered.

If a subject does not administer or take all study medication including vitamin D or calcium, the reason for the missed dosing is to be recorded in source documents and on the eCRF.

Returned, unused alendronate will be accounted for by the study site and destroyed as appropriate.

5.6 Unblinding of Study Medication

6.0 CONCOMITANT MEDICATIONS

6.1 Concomitant Medications

Vitamin D and calcium supplements are required to be administered daily from Day 1 (continuing from Protocol BA058-05-003) until the Month 6 Visit. Vitamin D and calcium supplements will be administered in the following doses: 400-800 IU/day (Vitamin D) and 500-100mg/day (calcium), or at a dose to be determined by the Investigator according to the subjects need. The doses and schedule of Vitamin D and calcium supplements, which are part of the study medication protocol, should be adhered to and not be changed other than for medical necessity. The supplements should be taken in the evening with or without food or as otherwise instructed by the Investigator.

For any required concomitant medication, such as statins or antihypertensives, the subject must be on a stable dose at study entry and every effort should be made to maintain a stable dose during study participation.

The occasional use of over-the-counter medications at approved doses (e.g., ibuprofen or acetaminophen) for headache or minor discomfort is allowed. Occasional short term (<3 months) use of corticosteroids for seasonal allergies or asthma is also allowed. These are to be recorded on the appropriate case report form. Subjects should not take any other medications, including over-the-counter medications, herbal medications, or mega-doses of vitamins during the study without prior approval of the Investigator.

If it becomes necessary for a subject to take any other medication during the study, the specific medication(s) and indication(s) must be discussed with the Investigator. All concomitant medications taken during the course of the study must be recorded in the Subject’s medical record or source document and transcribed into the case report form.

6.2 Prohibited Medications

Subjects who require treatment during the course of the study with either an anticonvulsant (phenobarbital, phenytoin, carbamazepin or primidone) or chronic treatment with any form of heparin will be discontinued. Estrogens given as HRT are allowed at entry into the study but cannot be initiated during the study except for local low dose vaginal estrogen.

Drugs that may compromise renal function such as non-steroidal anti-inflammatory drugs should be used with caution.

7.0 STUDY ASSESSMENTS

Subjects randomized to Abaloparatide-SC/Placebo in Study BA058-05-003 will receive alendronate at a dose of 70 mg once per week for a total of 24 months.

The assessments performed at each study visit are displayed in the Schedule of Visits and Procedures in Appendix 14.1. Appendix 14.2 provides a more detailed schedule of the study procedures by study visit with a suggested order of procedure conduct. Exact procedures for centrifuging, storage, and shipping of laboratory samples will be detailed in a separate document.

Study-specific assessments are to be conducted only after the subject has provided written informed consent to participate in this study. The study assessments are described in more detail in Section 7.1 below.

7.1 Clinical Procedures/Assessments

7.1.1 Informed Consent

At the End-of-Treatment Visit (Visit 9) for Study BA058-05-003, the possibility of participating in the Extension Study will be discussed with the subjects randomized to Abaloparatide-SC/Placebo. The Informed Consent must be signed prior to undergoing any BA058-05-005 study related procedures, and may be signed at either Visit 9 or Visit 10 of Study BA058-05-003.

7.1.2 Recent Health Status

The subject’s health status will be updated from their last visit in Study BA058-05-003, as necessary. Any changes in health status should be recorded as an adverse event, as appropriate.

The physical examination from the End-of-Treatment visit (Visit 9) of Study BA058-05-003 will be the baseline for this study (Day 1).

Interim or symptom-directed physical examinations may be performed at the discretion of the Investigator, if necessary, to evaluate adverse events or clinical laboratory abnormalities.

7.1.3 Xxxxx Xxxxx

Blood pressure, body temperature (ºC), pulse (bpm) and respiration rate (breaths per minute) are to be measured and recorded at each study visit (Day 1, Month 3 and Month 6, Month 12, Month 18 and Month 24). Only the Day 1 blood pressure assessments need be conducted as an orthostatic measurement (See Section 7.1.5).

7.1.4 Height and Weight

Height and weight are to be measured at each study visit (Day 1, Month 3, Month 12, Month 18 and Month 24). Height is to be measured in the standing position using a medical stadiometer.

7.1.5 Orthostatic Blood Pressure and Heart Rate

The Day 1 orthostatic blood pressure measurement for Study BA058-05-005 will serve as the Visit 10 orthostatic blood pressure for Study BA058-05-003. Blood pressure (mmHg; measured in the same arm at each visit) and pulse rate (bpm) will be measured after five minutes in the supine position. Immediately following this measurement, blood pressure will be measured again after three minutes in the standing position.

7.1.6 Electrocardiogram

A twelve-lead supine electrocardiograms (ECGs) will be performed and the following ECG parameters will be recorded: rhythm, heart rate, PR interval, QRS duration and QT/QTc.

The Day 1 ECG measurement for Study BA058-05-005 will serve as the Visit 10 ECG measurement for Study BA058-05-003. An ECG will also be obtained at Month 6.

7.1.7 Clinical Laboratory Evaluations

Clinical laboratory evaluations will be performed by a central laboratory. Prior to starting the study, the Sponsor (or its designee) will provide each Investigator with copies of the appropriate laboratory certifications and normal ranges for all laboratory parameters to be performed by that laboratory.

The blood and urinalysis samples are to be obtained under fasting conditions (NPO for 8 hours; water is acceptable) in the morning of each scheduled study visits on Day 1 and Months 6, 12, 18, and 24.

All clinically significant laboratory abnormities indicating an adverse event will be followed up by repeat testing and further investigated as necessary, according to the judgment of the Investigator.

7.1.8 Clinical Chemistry and Urinalysis (Dipstick)

Clinical chemistry and dipstick urinalysis will be performed on Day 1 and at Months 6, 12, 18, and 24. Urinalysis will be performed using samples freshly voided during the clinic visit. If there are positive findings noted on the dipstick, a urine microscopic examination will be performed. The following tests will be performed:

Serum Chemistry	·	Sodium
	·	Potassium
	·	Chloride
	·	Inorganic phosphorus
	·	Albumin

7.1.10 Coagulation

Coagulation testing will be performed on Day 1 and at Months 6 and 24. The following tests will be performed:

	·	Prothrombin time (PT)
	·	Partial thromboplastin time (PTT)

7.1.11 24-Hour Urine Collection

The 24-hour urine collection is to be begun the day before the Day 1 and Month 6 visits. If a sample was not able to be collected on the day prior to the Day 1 visit (i.e., if the subject had not yet signed the ICF for study participation), a 24-hour urine sample must be collected on the day prior to the Month 3 visit. Subjects are to be instructed to begin the urine collection by discarding the first morning void (~6 a.m.) the day prior to the scheduled clinic visit and to then collect their urine for 24 hours. A final void is to be collected at the end of the 24-hour period and the urine collection transported to the clinic by the subject. The 24-hour urinalysis will be used to measure urinary calcium and urinary creatinine.

7.1.12 Bone Mineral Density

All subjects will have bone mineral density measurements (BMD) taken via DXA at Months 6, 12, 18, and 24. The End-of-Treatment (Visit 9) bone mineral density tests for Study BA058-05-003 will serve as the baseline BMD measurements for Study BA058-05-005.

DXAs will be performed on the hip (femoral neck) and spine (L1-4). The spinal DXA is to be taken in the postero-anterior (PA) projection with any subsequent spinal DXA to be taken in the same projection. Subjects who underwent wrist DXAs in Study BA058-05-003 will also have wrist DXAs performed at Months 6, 12, 18, and 24. The same side of the hip and wrist that were used in Study BA058-05-003 must be used for the DXA scan, and the same scanner should be used throughout the study, when possible.

If the independent radiologist identifies any patient who shows a continuing significant deterioration from the Day 1 assessment of Study BA058-05-005 (>7%) of BMD at spine or hip during the study, the study physician will be notified, the assessment will be repeated

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

and, if confirmed, the patient will be discontinued from the study. The study physician will make this determination on the basis of the centrally read DXA relative to the baseline measurement in consultation with the Sponsor Medical Monitor.

7.1.13 Serum Markers of Bone Metabolism

Blood samples to measure bone markers will be taken on Day 1 and at Months 6, 12, 18 and 24. The results of the bone markers will be reported in the same subset of subjects reported on for Study BA058-05-003.

The following markers of bone formation will be measured:

· Serum N-terminal propeptide of type I procollagen (PINP);

· Serum bone-specific alkaline phosphatase (BSAP);

· Serum osteocalcin.

The following marker of bone resorption will be measured:

· Serum C-telopeptides of type 0 xxxxxxxx xxxxxxxxxx (XXX).

7.1.14 Clinical and Radiologic Evaluation of Fractures

Subjects will undergo protocol directed antero-posterior and lateral radiographs of the lumbar and thoracic spines at Month 6 and Month 24. The End-of-Treatment (Visit 9) clinical and radiological evaluation of fractures for Study BA058-05-003 will serve as the baseline assessments for Study BA058-05-005. Subjects will also be clinically evaluated for non-vertebral fractures (wrist, hip, rib, etc.) that occur de novo during the Treatment Period. Documentation should be obtained on all de novo fractures that occur during the Treatment Period. This documentation should be maintained in the source documents.

All radiographs will be viewed and assessed centrally by a blinded, independent assessor (radiologist) on the basis of existing baseline and study-acquired vertebral deformity. Fractures will be assessed according to the severity scale of Genant (1993). A second blinded radiologist will confirm the assessment of the first reviewer for all subject radiographs in which an incident fracture has been identified. In the case of any disagreement, a third consensus assessment will be made to adjudicate the incident fracture.

Fractures identified during the study will not be recorded as AEs unless the subject is hospitalized, the fracture is complicated, or the Investigator considers the fracture to be unrelated to the subject’s underlying osteoporosis. All fractures (vertebral and non-vertebral) will be identified and evaluated as part of the disease assessment and will be documented in the fracture page of the case report form and source documents.

7.1.15 Abaloparatide Antibody Assessments

The occurrence of anti-drug antibodies will be assessed at the completion of the initial six months of the study. Serum samples will be drawn at Month 6. Any subject who tests positive, or has previously tested positive for antibodies will be retested at six month intervals until the antibody titer is negative. At the completion of the 24 months of the study, if the subject is still antibody positive, the subject will sign a new consent form to allow the antibody draws to continue. Exact procedures for collection, preparation, storage, and shipping of these samples will be detailed in a separate document. During the 24 months of the study, the actual time and date of each blood collection will be recorded on the

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

appropriate source document and in the eCRF. Information on antibodies collected subsequent to the 24 months of the present study will be collected in a paper or electronic CRF.

7.1.16 Subject Diaries

A weekly diary will be completed by the subject beginning on the Day 1 visit and continuing until the last day of Month 24. This diary will capture missed doses of vitamin D, calcium and alendronate. The weekly diary will be reviewed at each study visit.

7.1.17 Activity and Diet

Subjects who qualify for enrollment in the study will have no restrictions placed on their usual level of activity or on their usual diet, unless directed by the treating physician for medically justified reasons.

8.0 ADVERSE EVENTS AND SAFETY EVALUATION

Timely, accurate, and complete reporting and analysis of safety information from clinical studies are crucial for the protection of subjects, Investigators and the Sponsor, and is mandated by Regulatory Agencies worldwide. All clinical trials sponsored by RADIUS will be conducted in accordance with Standard Operating Procedures (SOPs) that have been established to conform to regulatory requirements worldwide to ensure appropriate reporting of safety information.

8.1 Definitions, Documentation, and Reporting

8.1.1 Adverse Event Definition

An adverse event (AE) is any untoward medical occurrence in a subject administered a pharmaceutical product, which does not necessarily have a causal relationship with the treatment. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug, whether or not it is considered to be study drug related. This includes any newly occurring event or previous condition that has increased in severity or frequency since the administration of study drug.

8.1.2 Serious Adverse Event Definition

A serious adverse event (SAE) is any adverse event, occurring at any dose and regardless of causality that:

· Results in death.

· Is life-threatening. Life-threatening means that the subject was at immediate risk of death from the reaction as it occurred, i.e., it does not include a reaction which hypothetically might have caused death had it occurred in a more severe form.

· Requires in-patient hospitalization or prolongation of existing hospitalization. Hospitalization admissions and/or surgical operations scheduled to occur during the study period, but planned prior to study entry are not considered AEs if the illness or disease existed before the subject was enrolled in the trial. Provided that the illness/disease did not deteriorate in an unexpected manner during the trial (e.g., surgery performed earlier than planned).

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

· Results in persistent or significant disability/incapacity. Disability is defined as a substantial disruption of a person’s ability to conduct normal life functions.

· Is a congenital anomaly/birth defect. This includes any anomaly detected at or after birth, or any anomaly that results in fetal loss.

· Is an important medical event. An important medical event is an event that may not result in death, be life-threatening, or require hospitalization, but may be considered an SAE when, based upon appropriate medical judgment, it may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes listed in the definitions for SAEs. Examples of such medical events include allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias or convulsions that do not result in in-patient hospitalization, or the development of drug dependency or drug abuse.

Clarification should be made between the terms “serious” and “severe” since they are not synonymous. The term “severe” is often used to describe the intensity (synonym: severity) of a specific event (as in mild, moderate, or severe myocardial infarction); the event itself, however, may be of relatively minor medical significance (such as a severe headache). This is not the same as “serious,” which is based on subject/event outcome or action criteria described above and are usually associated with events that pose a threat to a subject’s life or functioning. A severe adverse event does not necessarily need to be considered serious. For example, persistent nausea of several hours duration may be considered severe nausea but not an SAE. On the other hand, a stroke resulting in only a minor degree of disability may be considered mild, but would be defined as an SAE based on the above noted criteria. Seriousness (not severity) serves as a guide for defining regulatory reporting obligations.

8.2 Monitoring of Adverse Events and Period of Observation

All AEs will be monitored until they are resolved or have become chronic or stable. AEs and SAEs will be recorded on the case report forms starting from the time of subject entry from Day 1 of the study until the final study visit (Month 24). Any SAEs that occur at any time after completion of the study, which the Investigator considers to be related to study drug, must be reported to the Sponsor or its designee.

8.3 Procedures for Recording and Reporting AEs and SAEs

All adverse events spontaneously reported by the subject and/or in response to an open question from study personnel or revealed by observation, physical examination or other diagnostic procedures must be recorded in the source document and on the appropriate page of the case report form. Any clinically relevant deterioration in laboratory assessments or other clinical findings is considered an adverse event and must be recorded on the appropriate pages of the case report form. When possible, signs and symptoms indicating a common underlying pathology should be noted as one comprehensive event.

All SAEs that occur during the course of the study, as defined by the protocol, must be reported by the Investigator to the Study Safety Officer by completing and transmitting the SAE Form within one working day from the point in time when the Investigator becomes aware of the SAE. In addition, all SAEs including all deaths, which occur up to and including 30 days after administration of the last dose of study drug, must be reported to the Study Safety Officer within one working day. All SAEs and deaths must be reported

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

whether or not considered causally related to the study drug. SAE forms will be provided to the study site. The information collected will include a minimum of the following: Subject number, a narrative description of the event, and an assessment by the Investigator as to the intensity of the event, and relatedness to study drug. Follow-up information on the SAE may be requested by the CRO, the Study Safety Officer or the Sponsor Medical Monitor. Contact information for reporting SAEs to the Study Safety Officer is provided on the SAE form.

It is the responsibility of the Investigator to promptly notify the Institutional Review Board (IRB)/Independent Ethics Committee (IEC) of all serious adverse drug reactions involving risk to human subjects in accordance with the requirements of the IRB/IEC. An unexpected event is one that is not reported in the Investigator’s Brochure.

Planned hospital admissions or surgical procedures for an illness or disease that existed before the subject was enrolled in the trial or before study drug was given are not to be considered AEs unless they occur at a time other than the planned date.

Fractures identified during the study are not to be recorded as AEs unless the subject is hospitalized, the fracture is complicated, or the Investigator considers the fracture to be unrelated to the subject’s underlying osteoporosis. All fractures will be identified and evaluated as part of the disease assessment and will be documented in the case report forms and source documents.

For both serious and non-serious adverse events, the Investigator must determine the intensity of the event and the relationship of the event to study drug administration. Intensity for each AE will be defined according to the following criteria:

Intensity		Definition

Mild		Awareness of sign or symptom, but easily tolerated.

Moderate		Discomfort enough to cause interference with normal daily activities.

Severe		Inability to perform normal daily activities

If the intensity of an adverse event changes within a day, the maximum intensity should be recorded. If the intensity changes over a longer period of time, the changes should be recorded as separate events (having separate onset and stop dates for each intensity).

Relationship to study drug administration will be determined by the Investigator according to the following criteria:

Relationship		Definition

None		No relationship between the event and the administration of study drug. The event is related to other etiologies, such as concomitant medications or subject’s clinical state.

Unlikely		The current state of knowledge indicates that a relationship to study drug is unlikely or the temporal relationship is such that study drug would not have had any reasonable association with the observed event.

Possible		A reaction that follows a plausible temporal sequence from administration of the study drug and follows a known response pattern to the suspected study drug. The reaction might have

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

Radius Health, Inc.

Confidential

		been produced by the subject’s clinical state or other modes of therapy administered to the subject.

Probable		A reaction that follows a plausible temporal sequence from administration of the study drug and follows a known response pattern to the suspected study drug. The reaction cannot be reasonably explained by the known characteristics of the subject’s clinical state or other modes of therapy administered to the subject.

For the purpose of safety analyses, all AEs that are classified with a relationship to study medication administration of possible or probable will be considered treatment-related events.

8.4 Rules for Suspension of the Study

As this is an extension study using approved alendronate products it is not anticipated that the study will need to be suspended, and therefore, suspension rules are not assigned. In the event that the prior study (Study BA058-05-003) is suspended, the circumstances of the Study BA058-05-003 suspension will be considered to determine if this study, Study BA058-05-005, should be suspended as well.

9.0 STATISTICAL PROCEDURES

The primary objective of this study is to evaluate data obtained following six months of treatment with alendronate, in subjects who have previously received 18 months of blinded treatment with Abaloparatide-SC/Placebo. Safety data will be obtained with clinical, laboratory and radiologic assessment. Following the initial six months of treatment in this study, subjects will then enter the long-term observational phase of this study during which the subjects will continue to receive alendronate treatment for an additional 18 months.

The specific objectives of this study are to:

· Provide additional information on safety in study subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide information on the vertebral fracture rate of subjects receiving six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on non-vertebral fractures and BMD change associated with six months of treatment with alendronate following 18 months of treatment with Abaloparatide-SC/Placebo.

· Provide additional information on BMD change and osteoporosis status associated with 24 months of treatment with alendronate after 18 months of treatment with Abaloparatide-SC/Placebo.

The analysis performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. Analyses will also be performed cumulatively at Month 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of the statistical procedures to be used will be provided in the Statistical Analysis Plan.

9.1 Sample Size

As this is an extension study, no formal sample size analysis was performed for this study. Study data will be tabulated and summarized.

9.2 Randomization, Stratification and Blinding

Osteoporosis treatment will be open label and no randomization is required.

9.3 Populations for Analysis

All analyses and data summaries will be presented for the Intent-to-Treat (ITT) or Safety Population. In addition key selected endpoints will also be analyzed for the mITT and Per Protocol Populations.

9.3.1 ITT (Safety) Population

The Safety Population is comprised of all patients who receive one or more doses of study medication.

9.3.2 Modified Intent-to-Treat Population

The Modified ITT Population includes all patients with Pretreatment and at least one post-baseline evaluable radiologic assessments.

9.3.3 Per Protocol Population

The Per-Protocol (PP) population includes subjects in the mITT population who complied with treatment and did not have any protocol violations.

A protocol violation is defined as a deviation from basic requirements of the study protocol, including inclusion and exclusion criteria, concomitant medication restrictions, or any other protocol requirements that result in a significant added risk to the study subject or has an impact on the quality of the data collected or the outcome of the study.

A protocol deviation is defined as a deviation from the protocol that does not impose added risk to the study design or the study subject. The criteria for the determination of the evaluability of subjects will be defined in the Statistical Analysis Plan.

9.4 Procedures for Handling Missing, Unused, and Spurious Data

All available data will be included in the data listings and tabulations. Where appropriate, imputations of values for missing data for primary and secondary efficacy analyses will be performed as specified in the Statistical Analysis Plan. All data recorded on the CRF will be included in the data listings that will accompany the clinical study report.

9.5 Statistical Methods

9.5.1 Statistical Considerations

Statistical analysis will focus on safety, fracture incidence, including vertebral fracture and BMD change following six months of alendronate treatment in subjects who have previously received 18 months of blinded treatment with Abaloparatide-SC/Placebo. Additional

Protocol BA058-05-005 Amendment 4, Version 1 (24 August 2015)

analyses will also be cumulatively at Month 12, 18, and 24 (i.e., Visit 4, 5, and 6). Full details of these analyses will be provided in the Statistical Analysis Plan.

The efficacy and safety analyses performed at six months will be used as a follow-up to the 18 month fracture endpoint for Study BA058-05-003. Subjects will be analyzed based upon the randomization assignment in the BA058-05-003 study.

9.5.2 Baseline Comparisons

Baseline characteristics, medical history, physical examination, xxxxx xxxxx and ECG, will be summarized using standard descriptive statistics.

9.5.3 Fractures and BMD Analysis

All specified endpoints will be summarized by treatment group and study period using standard descriptive statistics (n, mean, SD, median, minimum, maximum, or n and %, as appropriate). The fracture incidence and BMD results from the additional six months of treatment with alendronate will be analyzed based on the treatment arm they were randomized to in the BA058-05-003 study. These analyses will be conducted on all subjects with baseline and post-baseline data. The analysis performed at six months will be used a follow-up to the 18 month fracture endpoint for Study BA058-05-003.

Vertebral fractures based on radiologic assessments will also be analyzed at Month 24. Additional analyses for the other endpoints will also be performed cumulatively at Month 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of these analyses will be provided in the Statistical Analysis Plan.

9.5.4 Safety Analysis

· Incidence and severity of AEs;

· Pathological changes in hematology, chemistry and urinalysis data based on normal ranges supplied by the clinical laboratory, if applicable;

Safety assessments for changes in physical examination, xxxxx xxxxx, ECG, and laboratory tests will be descriptively summarized by treatment and study periods. The results of anti-BA058 testing will be summarized. Concomitant medication classes will be categorized using World Health Organization (WHO) drug dictionary and summarized by number and percent of subjects using each class by treatment group. All treatment emergent adverse events (TEAEs) will be coded for system organ class (SOC) and preferred term (PT) using MedDRA and the number (%) of subjects experiencing each AE (SOC/PT) will be summarized by treatment, relationship to treatment, and severity. All serious adverse events (SAE) will be listed and the number (%) of subjects with an SAE presented by treatment group.

Similar safety analyses will be conducted cumulatively at Months 12, 18, and 24 (i.e., Visits 4, 5, and 6). Full details of these analyses will be provided in the Statistical Analysis Plan.

9.5.5 Procedures for Reporting Deviations to Original Statistical Analysis Plan

study report.

9.6 Data Oversight

9.6.1 Central Review of Radiographs and DXA Scans

All radiographs will be viewed and assessed by a blinded, independent assessor (radiologist) on the basis of existing baseline and study-acquired vertebral deformity, and fractures will be assessed according to the method of Genant. A second blinded radiologist will review the assessment of the first reviewer for all subject radiographs in which an incident fracture has been identified. In the case of any disagreement, a third consensus assessment will be made to adjudicate the incident fracture. All study DXA scans will also be evaluated centrally by a blinded independent reviewer. The primary objective of the independent review is to provide objective data to determine the treatment benefit as demonstrated on the pertinent radiologic and clinical data associated with this study.

10.0 ADMINISTRATIVE REQUIREMENTS

10.1 Good Clinical Practice

This study will be conducted in accordance with the International Conference on Harmonization (ICH) for Good Clinical Practice (GCP) and the appropriate regulatory requirements. The Investigator will be thoroughly familiar with the appropriate use of the study medication as described in the protocol and the Investigator’s Brochure. Essential clinical documents will be maintained to demonstrate the validity of the study and the integrity of the data collected. The Investigator/institution should establish master files at the beginning of the study which will be maintained and updated during the study and retained thereafter according to the appropriate regulations.

10.2 Ethical Considerations

The study will be conducted in accordance with ethical principles founded in the Declaration of Helsinki. The Institutional Review Board (IRB)/Independent Ethics Committee (IEC) will review all appropriate study documentation in order to safeguard the rights, safety and well-being of the subjects. The study can only be conducted at study sites where IRB/IEC approval has been obtained. The protocol, informed consent form, Investigator’s Brochure, advertisements (if applicable), and all other forms of information given to subjects will be provided to the IRB/IEC by the Investigator. In addition, reports on the progress of the study will be submitted to the IRB/IEC by the Investigator at the appropriate intervals.

10.3 Subject Information and Informed Consent

Each subject (or a legally authorized representative) must give written informed consent prior to any new study-specific procedures being conducted. It is the responsibility of the Investigator to ensure written informed consent is obtained from each subject participating in this study after an explanation of the objectives, methods, discomforts and potential risks of the study has been provided. The Investigator (or study personnel) must also explain to each subject that he/she is free to refuse participation in the study or to withdraw from it at any time. Each subject will also be told that his/her records may be examined by competent authorities and authorized persons but that personal information will be treated as strictly confidential and will not be publicly available.

10.7 Study Monitoring

The Sponsor (or its designee) will ensure that the study is monitored in accordance with ICH-GCP Guidelines. Monitoring is the act of overseeing the progress of a clinical trial and of ensuring that it is conducted, recorded, and reported in accordance with the protocol, standard operating procedures, Good Clinical Practice, and the applicable regulatory requirements and that the study data are accurate, complete and verifiable from source data. All study documentation and other source data will be made available to the Sponsor (or its designee), the IRB and to Regulatory Authorities for inspection upon request.

10.8 On-Site Audits

Representatives of the IRB or the Sponsor (or designee) may visit the study site to carry out an audit of the study in compliance with regulatory guidelines and company policy. Such audits will require access to all study records including source documents, CRFs, and other study documents. Direct access to these study records must be guaranteed by the Investigator, who must provide support for these activities at all times.

Similar auditing procedures may also be conducted by agents of any Regulatory Authority reviewing the results of this study. The Investigator/institution should immediately notify the Sponsor if they have been contacted by a Regulatory Authority concerning an upcoming inspection.

10.9 Drug Accountability

Accountability for the study medication at the study site is the responsibility of the Investigator. Drug accountability will be performed only on alendronate, calcium and vitamin D. The Investigator will ensure that the study medication is used only in accordance with this protocol. Where allowed, the Investigator may choose to assign some of the study medication accountability responsibilities to qualified study personnel.

Study medication accountability records indicating the delivery date to the study site, inventory at the study site and dispensing/use will be maintained. These records will adequately document that the study medications were dispensed and returned as specified in the protocol. Accountability records will include dates, quantities, and subject numbers. The Sponsor (or its designee) will review study medication accountability records at the study site on an ongoing basis during the study. All used and unused study medication must be inventoried, accounted for, and approved by the Sponsor (or its designee) prior to destruction. If the site is not capable of study drug disposal/destruction, the Sponsor will arrange for an alternative method. Records of disposal must be maintained with the study records.

10.10 Record Retention

The Investigator will maintain all study records according to ICH/GCP and applicable regulatory requirements. Essential documents must be retained for two years after the final marketing approval in an ICH region or at least two years have elapsed since the discontinuation of clinical development of the study medication. It is the responsibility of the Sponsor to inform the Investigator of when these documents can be destroyed. In addition, all subject medical records and other source documentation will be kept for the maximum time permitted by the hospital, institution or medical practice.

(1) The procedures for the Follow-up visit (Visit 10) for Study BA058-05-003 will serve as the procedures performed at Day 1 (for Study BA058-05-005). The consent form will need to be signed if it was not signed during the End-of-Treatment Visit (Visit 9) of Study BA058-05-003.

(2) Xxxxx xxxxx (blood pressure, pulse rate, body temperature, and respiration rate) are to be recorded at each study visit. Only the blood pressure assessment on Day 1 (Visit 10) needs to be orthostatic. Height is to be measured at each visit in the standing position using a medical stadiometer. Weight is to be measured at each visit. Orthostatic blood pressure is to be measured initially after 5 minutes in the supine position and then again after standing for three minutes.

(3) All routine urinalysis will be performed on a sample freshly voided during the clinic visit.

(4) These blood samples are to be obtained under fasting conditions (N.P.O. for 8 hours; water is acceptable) in the morning of each scheduled study visit.

(5) Includes blood samples for PINP, bone-specific alkaline phosphatase, serum osteocalcin and CTX.

(6) Subjects who remain positive at the 6 month antibody draw will have samples drawn for antibodies every six months until the antibody titer is negative.

(7) Twenty-four hour urine collection will be used for urinary calcium and urinary creatinine measurements. Subjects will discard the 1st void and begin a 24-hour urine collection the day prior to the clinic visit.

(8) A 24-hour urine collection will be collected at Month 3 only if a sample was not collected for the Day 1 (Visit 10).

(9) Documentation should be obtained on all de novo fractures that occur during the Treatment Period. This documentation should be maintained in the source documents.

(10) Each DXA for a given subject should be performed on the same machine, and if available, preferably by the same technician

(11) Each DXA for a given subject should be performed on the same machine, and if available, preferably by the same technician. Only subjects who had wrist DXA assessments in Study BA058-05-003 will have wrist DXAs performed.

(12) The subjects will maintain a diary throughout the study to record missed doses of medication (including supplements) on a weekly basis; the diaries are to be reviewed with the subject at each study visit.

14.2 Suggested Schedule of Events and Procedures by Study Visit

The purpose of this guide is to provide more detailed instructions for the study procedures listed in Appendix 14.1. This guide presents the procedures in a suggested sequence of performance at each study visit. Further information may be found within the protocol and in other study reference manuals (e.g., ECG, clinical laboratory sample processing).

Of note:

· Blood and urinalysis samples are to be obtained under fasting conditions (NPO. for 8 hours; water is acceptable) in the morning of Day 1 and Months 6, 12, 18, and 24.

· DXA Scans: Always use the same study-validated machine; preferably the same technician.

· The 24-hour urine collection will be started at home the day before the clinic visit where the collection is required. Subjects will be instructed to discard the first morning void and begin the collection at least 24 hours before their clinic visit the following day. They will collect all urine for 24 hours with a final void before coming to the clinic. Routine urinalyses are to be performed using samples freshly voided during the clinic visit. Subjects should receive a reminder to initiate their 24-hour urine 2 days before their scheduled visit.

· Alendronate for Europe, Hong Kong and the US will be sourced centrally; alendronate for South America will be sourced locally by the medical center and reimbursed by the Sponsor.

· Subjects will be instructed to take the calcium and vitamin D supplements daily (in the evening with or without food or as otherwise instructed by the Investigator) until discharge from the study. This is required until the end of Month 24.
