GSK Press release:

Issued: [DAY + XXXXX] 0000, Xxxxxx XX

GSK exercises option on phase 1/2 NY-ESO T-cell therapy (GSK3377794)

Today GSK announced that it has exercised the option to obtain an exclusive global license from Adaptimmune for an investigational SPEAR T-cell receptor therapy targeting NY-ESO-1 (GSK3377794). Upon exercise of this option and transition of the programme, GSK will assume responsibility for all development, manufacturing and commercialisation activities for the asset.

Adaptimmune will receive up to £48 million from GSK over the course of the transition period. This includes development milestones of up to £18M and the option payment of £30 million, which also allows GSK to nominate two additional targets following completion of the transition. Successful continuation of development and subsequent commercialisation of GSK3377794 would trigger additional payments for development milestones, tiered sales milestones and mid-single to low double digit royalties on worldwide net sales.

Oncology is one of four Therapy Areas of focus for GSK’s R&D efforts, where the company believes there are significant opportunities for growth and innovation. GSK has three main areas of Oncology research: Cell and Gene Therapy; Cancer Epigenetics, and Immuno-oncology. There is tremendous potential for cells to be engineered into medicines and GSK is investing broadly to develop platform capabilities in manufacturing cell and gene therapies for use across a broad range of disease areas, including oncology.

Xxxx Xxxx, SVP Oncology R&D, GSK said “The aim of GSK’s R&D is to develop medicines with transformational potential for patients. We have seen compelling data for the NY-ESO investigational cell therapy in synovial sarcoma and, following this option exercise, we will capitalise on our in-house Cell and Gene Therapy capabilities to support the development programme for GSK3377794. We will continue to explore the potential for this novel cell therapy in multiple tumour types, and in combination with other cancer therapies.”

Xxxxx Xxxxx, Chief Executive Officer of Adaptimmune, said “This is a very exciting day for Adaptimmune as GSK has exercised its option over our NY-ESO program, earlier than originally planned. The commitment by one of the world’s leading pharmaceutical companies to the NY-ESO SPEAR T-cell program as a new treatment modality is a testament to the strength of our data in synovial sarcoma recently presented at ASCO.”

GSK3377794 has been granted PRIME designation by the European Medicines agency and Breakthrough Therapy Designation by the US Food and Drug Administration. There are currently six ongoing Phase 1/2 studies of GSK3377794 as monotherapy (NSCLC, Metastatic Melanoma, Ovarian, Multiple Myeloma, Synovial Sarcoma, and Myxoid Round Cell Liposarcoma) and one Phase 1 study in

combination with pembrolizumab in Multiple Myeloma. As part of the transition process, GSK will be developing a timeline for development activities, including initiation of new clinical studies.

GSK — one of the world’s leading research-based pharmaceutical and healthcare companies — is committed to improving the quality of human life by enabling people to do more, feel better and live longer. For further information please visit xxx.xxx.xxx.

GSK Exercises Option over SPEAR T-cell Therapy Program Targeting NY-ESO

PHILADELPHIA, Pa. and OXFORD, UK., September 7, 2017 — Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today announced that GlaxoSmithKline plc (LSE/NYSE:GSK) has exercised its option under a collaboration and license agreement signed in 2014 to exclusively license the right to research, develop, and commercialize Adaptimmune’s NY-ESO SPEAR T-cell therapy program. Further details will be provided in a conference call scheduled for 8:30 AM EDT this morning; dial-in and webcast details are provided below.

Adaptimmune will receive up to £48 million (~$61 million) from GSK over the course of the transition period. This includes development milestones of up to £18 million (~$23 million) and the option payment of £30 million (~$38 million), which also allows GSK to nominate two additional targets following completion of the transition. Successful continuation of development and subsequent commercialization of NY-ESO would trigger additional payments for development milestones, tiered sales milestones, and mid-single to low double-digit royalties on worldwide net sales.

“This is a very exciting day for Adaptimmune as GSK has exercised its option over our NY-ESO program, earlier than originally planned,” commented Xxxxx Xxxxx, Chief Executive Officer at Adaptimmune. “The commitment by one of the world’s leading pharmaceutical companies to the NY-ESO SPEAR T-cell program as a new treatment modality is a testament to the strength of our data in synovial sarcoma recently presented at ASCO. From a financial perspective, this option exercise extends our cash runway into 2020. We anticipate the transition of NY-ESO to GSK to be completed over the coming months, after which we will focus our clinical resources on delivery and execution from our wholly-owned assets MAGE-A4, MAGE-A10, and AFP.”

Xxxx Xxxx, SVP Oncology R&D, GSK said “The aim of GSK’s R&D is to develop medicines with transformational potential for patients. We have seen compelling data for the NY-ESO investigational cell therapy in synovial sarcoma and, following this option exercise, we will capitalize on our in-house Cell and Gene Therapy capabilities to support the development program for GSK3377794. We will continue to explore the potential for this novel cell therapy in multiple tumor types, and in combination with other cancer therapies.”

Summary of Recent Data in Synovial Sarcoma

In June of this year, data presented in an oral presentation at ASCO from the ongoing study of NY-ESO SPEAR T-cells in synovial sarcoma continued to indicate a favorable risk benefit profile in this aggressive and difficult-to-treat solid tumor. Initial anti-tumor activity was observed in all ongoing cohorts, including low expressors of NY-ESO. NY-ESO SPEAR T-cells continued to be well-tolerated with all reported events of cytokine release syndrome resolved (the majority of events were Grade 1 or 2), and there were no reported events of seizure, cerebral edema, or

encephalopathy. Survival data was promising with a median predicted overall survival of 120 weeks (~28 months) among the 12 treated patients in Cohort 1; or, 159 weeks (~37 months) for the ten patients in this cohort who received the target dose of one billion cells. In addition, 6 responses were observed in Cohort 1 patients.

Transition Plan

Adaptimmune and GSK will work together over the coming months to ensure a smooth transition of the NY-ESO SPEAR T-cell development program to GSK. After the transition, GSK will assume sponsor responsibility for all NY-ESO-related activities including ongoing data publications regarding this program Current plans for ongoing and planned clinical studies are summarized below by indication:

Sarcoma:

· Adaptimmune will continue enrollment in the ongoing synovial sarcoma pilot study, which will ultimately transition to GSK.

· GSK will be responsible for continued clinical investigation including initiating the registration study in this indication.

· Adaptimmune will continue to enroll patients in the ongoing myxoid/round cell liposarcoma (MRCLS) study, which will ultimately transition to GSK.

Non-small Cell Lung Cancer (NSCLC):

· Adaptimmune will cease enrollment in the ongoing NSCLC study, whilst GSK develops plans for its own study of NY-ESO SPEAR T-cells in this indication.

Ovarian:

· Adaptimmune will cease enrollment in the ongoing ovarian study, and GSK will assume responsibility for any additional work in this indication.

Multiple Myeloma:

· GSK will take on responsibility for the ongoing multiple myeloma combination study with KEYTRUDA® (pembrolizumab), an anti-PD-1 inhibitor marketed by Merck & Co., Inc., Kenilworth, NJ, USA (known as MSD outside the US and Canada).

About the Collaboration and License Agreement between Adaptimmune and GSK

Adaptimmune and GSK announced their strategic collaboration and license agreement in June 2014 for up to five programs including the first program, NY-ESO. The terms of the agreement were expanded in February 2016 to accelerate development of NY-ESO SPEAR T-cell therapy toward registration trials in synovial sarcoma, to explore development in MRCLS and to enable combination studies.

In January 2017, GSK nominated PRAME as a second target and, as a consequence of this option exercise for NY-ESO, GSK will have the right to nominate its third and fourth targets and Adaptimmune will take these programs through preclinical testing to IND. The agreement excludes targets on which work is already under way, including Adaptimmune’s wholly owned MAGE-A10, MAGE-A4, and AFP clinical programs and its active preclinical pipeline.

Adaptimmune’s Pipeline

Adaptimmune’s proprietary technology enables the Company to consistently generate affinity enhanced T-cell receptors (TCRs) which address intracellular targets on solid tumors that are not accessible to certain other experimental modalities. Adaptimmune has three wholly-owned SPEAR T-cells in active clinical trials, with further first and next generation SPEAR T-cells being developed and evaluated by means of Adaptimmune’s proprietary preclinical testing platform.

As stated above, GSK does not have the right to nominate any additional targets on which work is already under way, including Adaptimmune’s wholly-owned SPEAR T-cells targeting MAGE-A10, MAGE-A4, and AFP that are being evaluated in four active clinical trials across eight solid tumor indications., These ongoing studies are described in more detail below:

· MAGE-A10: Two active trials, one in NSCLC, and a triple tumor study in urothelial (bladder), melanoma, and head and neck cancer

· MAGE-A4: One active trial across seven solid tumor indications including urothelial, melanoma, head and neck, ovarian, NSCLC, esophageal, and gastric cancers

· AFP: One active study in hepatocellular (liver) cancer

Initial safety and efficacy data across each of these studies is anticipated through 2017 and 2018.
