1)Background

On March 19, ‘09, Xx. Xxxxx Xxxxxxxx asked for a cost proposal + timelines for upgrading the analytical methods, which were employed in the 0xx XX-000 campaign, to NDA filing levels. This was followed by a request for proposal on April 6, ‘09 for pricing for a 150 g Ph III / cGMP campaign. On April 29, ‘09 Radius placed a request to include pricing for a 200 g as well. The 04/30/09 2nd proposal amendment provides pricing for the 200 g. On Nov.23, ‘09 Radius requested a proposal for a 50 g batch for Phase 3 (requiring manufacture to GMP standards). On Nov.30, ‘09 Radius requested that pricing be added for a 100 g campaign as well. On Dec.3, ‘09, Radius requested a “break” on the 100 g price which Lonza is willing to give in support of Radius’ program.

In mid 2008 Xxxxx Xxxxxx performed the 0xx XX-000 campaign (C1 campaign) which yielded 59 g peptide corresponding to 50.7 g net peptide. An extra quantity of 7.5 g powder weight was generated during this first campaign.

Campaign summaries were provided in Process Analytical reports which were sent to Radius on March 2, ‘09 (PAR-S-RDS-001-I03 C1, concerning upstream process description) and on March 9, ‘09 (PAR-P-RDS-001-Campaign 1-Lot 8AG1, concerning downstream process description).

To date (April 20, ‘09) the following shipments were made out of this C1 campaign:

1) In February ‘09, 40.0 g (8 x 5.0 g powder weight) were sent to Xxxxxx Pharma (Germany).

2) In March ‘09, 4.0 g (1 x 1.5 g + 1 x 2.5 g powder weight) were sent to Xxxxxxx River Laboratories (Canada)

2) BA058—the Product

The BA058 (RDS-001) Peptide is an amide 34-mer with one non natural AA:

H-Ala-Val-Ser-Glu-His-Gln-Leu-Leu-His-Asp-Lys-Gly-Lys-Ser-Ile-Gln-Asp-Leu-Arg-Arg-Arg-Glu-Leu-Leu-Glu-Lys-Leu-Leu-Aib-Lys-Leu-His-Thr-Ala-NH2

Structure

The structure of BA058 peptide is depicted in Figure 1.

Figure 1: Structure of BA058 Peptide

The active pharmaceutical ingredient (API), BA058 API, is isolated with associated water and acetate.

3) Process:

The manufacturing process which Radius asked Lonza to quote on for the 1st campaign was outlined in the 4/17/07 RFP. The process is a solid-phase-peptide-synthesis process (SPPS) characterized by the stepwise addition of Fmoc-amino acids using Fmoc-AAs and coupling agents, followed by cleavage , deprotection and work-up; the purification is performed by reverse phase HPLC which is followed by isolation by means of lyophilization.

In the course of the feasibility study performed by Xxxxx Xxxxxx in early ‘08, two different analytical methods were developed in order to properly monitor purification of the peptide. These two methods provide much better resolution than the one received from Radius using a TFA based system.

During the C1 campaign, these methods were used for the monitoring of the primary purification of the peptide. This has resulted in an OOC (out of criteria), as the min. of 97.0% purity was not reached at the end of this step of purification.

In an internal meeting, it was decided to implement a second step of purification using acetic acid medium in order to increase the purity of fractions. At the same time, Radius requested to use the TFA method for the QC lot release. Lonza proposed to add one of our methods for supportive data during this release. By using Lonza’s analytical method, it was possible to produce an extra pure lot at 99.1% HPLC purity (Radius method). This means also that recovery and productivity were low due to a secondary step of purification and recycling to reach the required purity.

The new pricing is based on yields and recoveries obtained during the C1 campaign, which should not be considered as a representative campaign. For the future C2 campaign, norms to reach will be performed in TFA method (using the Radius HPLC method).

Concerning change of equipment, assembly of the peptide on the resin during C1 campaign has been performed in a 20 L-Pepsynloop reactor. For a batch size of 150g NPW API, a bigger reactor will be used, such as a 50L-Pepsynloop reactor. The upstream process will not be changed as the same technology is used in either reactor.

For the sake of this 1st amendment of the April 20th proposal all quantities to be produced have been revised, and the entire campaign has been recalculated. The final quantity to be produced is 150 g net peptide weight at 97.0% HPLC purity (by the Radius method) which is unchanged. The upstream will be performed in two small-scale SPPS reactors (2 x 20 L) in parallel vs. a single 50 L reactor in the initial proposal.

For the sake of the 2nd amendment a totally new production concept has been worked up and costed. In this case we can use mid-scale equipment: one run in 50 L SPPS reactor and LC200 for downstream; considerably less manpower is required in this production scenario resulting in considerable cost savings vs. a 150 g campaign.

For the sake of the 3rd amendment and as the request concerns the same batch size as for C1 campaign, we can use the same size equipment. This means, small-scale SPPS reactor (20 L) and LC150 for downstream. All improvements needed, coming from know-how acquired during C1 campaign, will be implemented in this new campaign.

4) Price Proposal and Assumptions for new 50 g and 100 g cGMP campaigns. The Quotation is in Euros (pro memoriam: the 11/30/09 US$ / Euro exchange rate is 1.5035):

	50 g	100 g
Raw Materials	12,250	24,250
Production (incl. SPPS, IPC, DSP)	160,550	~~207,750~~ 190,500
QC, QA release	37,200	43,000
TOTAL cost of 50 g campaign	Euros 210,000	Euros ~~275,000~~ Euros 257,750

A 50 g campaign is not well suited to the smallest reactor which we will have to use. A 100 g campaign is much better suited.

The target quality of the 50g and 100 g campaigns (NPW, net peptide weight) will be 97.0% (HPLC, Radius method).

In terms of timing, synthesis + purification + QA/QC release are estimated to take 14 weeks for the 50 g, 17 weeks for the 100 g campaign.

5) Price Proposal and Assumptions for a new 150 q cGMP campaign. The Quotation is in Euros (pro memoriam: the 04/28/09 US$ / Euro exchange rate is 1.3153): [SECTION 4 AND PRICING OF 150 G REMAINS UNCHANGED IN THE 2ND AMENMENT]

Prior to the start of production, specific raw material purchasing and their QC/QA release have to be scheduled. These tasks are estimated to take six weeks.

Production of 150g (NPW, net peptide weight) at 97.0% (HPLC, Radius method), including upstream, downstream, QC and QA release of the GMP lot.

Price : € 350.000 (all inclusive of raw materials, production, and margin)

This cost does NOT include Reference Standard qualification on this lot. New internal QA guideline is a separate RS from the batch (extra pure one, which means: two separate lyophilisation steps, 2 distinct QC releases and so on). Associated costs have been calculated as follows:

Assumptions :

· [ Extra pure API (part of the purification lot)

· Lyophilisation

· QC release] 16,335 €

· 5g net peptide weight 16,165 €

Total costs for a new reference standard: € 32,500

6) Price Proposal and Assumptions for a new 200 g cGMP campaign. The Quotation is in Euros (pro memoriam: the 04/30/09 Euro / US$ exchange rate is 1.3205):

Prior to the start of production, specific raw material purchasing and their QC/QA release have to be scheduled. These tasks are estimated to take six weeks.

Production of 200g (NPW, net peptide weight) at 97.0% (HPLC, Radius method), including upstream, downstream, QC and QA release of the GMP lot.

Price : € 285,000 (all inclusive of raw materials, production, and margin ; excluding the €12,500 cost for the new stationary phase for the larger column)

Assumptions :

· [ Extra pure API (part of the purification lot)

· Lyophilisation

· QC release] 16,335 €

· 5g net peptide weight 10,000 €

Total costs for a new reference standard: € 26,335

7) Price Proposal for Upgrading of Analytical Methods to NDA filing levels. The Quotation is in Euros (pro memoriam: the 04/17/09 Euro / US$ exchange rate is 1.3043):

1. Analytical activities (this should be performed in parallel of the GMP campaign, concerning validation methods. For additional testing 3 extra weeks are needed after the release of the lot).

· Validation of analytical methods : Price € 100,000

· HPLC / M-009-RDS-001TG1 (QC release method)

· HPLC / M-009-RDS-001FG1 (QC release method)

· Acetate and Trifluoroacetate content in API

· Water content

· GC-Headspace (complement to general method)

· Direct GC (complement to general method)

· Specific rotation

· Peptide content (Nitrogen)

· HPLC for in-process control upstream and downstream (3 methods).

· Additional testing requested for NDA filling : Price: € 25,000

· LC-MS profiles of one lot + one lot in stability study (study of degradation of API: impurity profile).

· Comparability study for lots coming from different suppliers

· Heavy metals

· General properties: polymorphism, solubility, pH (isoelectric point), appearance, etc...

For all this analytical work, 10 g powder weight of API is needed. We still have 15 g powder weight of lot 8AG1 in stock. We will be able to use this material if Radius so decides. Otherwise, we will have to use an extra quantity to be made available from this lot (this one has not been paid yet by Radius). This will be discussed with Radius when necessary.

Total price: € 125,000

2. Regulatory activities

NDA filing. Price: € 57,500

15 weeks will be needed to finalize the NDA writing and associated corrections.

Analytical Development Proposal for BA058, API project (Lonza RDS-001)

CONFIDENTIAL

Lonza

Analytical Development Proposal for BA058, API project

(Lonza RDS-001)

Development proposal

The development proposal is divided into 3 steps that should be conducted prior to the next API batch release.

1. HPLC methods comparability

A first step will be to establish method comparability between TG1, VG1 and FG1 HPLC methods, in order to understand the capabilities and pitfalls of these methods for true process impurities, including [3-34] and [4-34] truncated peptides. The HPLC data will be backed up by LC/MS data to support identification of impurities and methods comparability in case of co-elution of impurities (either with the main peak or with other impurities).

This will also allow building a rationale for method change in future API release specifications.

This method comparability would be based on Lonza samples (including previously manufactured lots 5AG1R and 8AG1, [3-34] and [4-34] impurity markers, as well as DSP side fractions containing process impurities). Should it be of interest to Radius, samples of BA058, API from other sources could also be added to this study in order to bridge these materials with the current Lonza material (8AG1).

Requirement: Samples from Radius (if needed)

Timeline: 4 weeks

Deliverable: Comparability report between 3 HPLC methods, including LC/MS identification of impurities.

Price: €15,000

2. Additional method development

Based on the above assessment, additional HPLC method development may have to be performed, in order to identify the method of choice (separate the criticial [3-34] and [4-34] from the other process impurities), in addition to the identified HPLC method that will be used to assess overall purity and individual impurities.

For this, we could use alternative stationary phases (eg HILIC) or even move to UPLC (more resolution power than HPLC)

Timeline: 4 weeks

Deliverable: HPLC method Development report

Price: €15,000

3. HPLC methods qualification

Once identified, the methods of choice (probably two) found suitable for their intended purposes (quantitation of process impurities, and stability-indicating to support ICH stability studies of API and DP) will be qualified. One of these methods could also be used to determine the API content in the powder (against an external reference standard), should this be a requirement from Radius. This method qualification work will have to be completed before initiation of the next campaign release.

Timeline: 5 weeks (assuming 2 methods qualified in parallel)

Deliverable: HPLC method Qualification protocol and report

Price: € 18,000 per method (in line with any previous proposal for method qualification)
