PHILADELPHIA and OXFORDSHIRE, United Kingdom, Nov. 06, 2019 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc ADAP, a leader in T-cell therapy to treat cancer, today reported financial results and business highlights from Q3 2019.

"The sarcoma community has been very supportive following the ESMO presentation in which we showed a clear benefit for ADP-A2M4. This increases our confidence that we can accelerate enrollment in SPEARHEAD-1 as we progress toward commercialization in 2022," said Adrian Rawcliffe, Adaptimmune's Chief Executive Officer. "We continue to see evidence of antitumor activity with our SPEAR T-cells across other indications. We are executing with our ADP-A2AFP trial, now dosing in Cohort 3, as well as our next‑gen SURPASS trial, and we plan on updating data throughout 2020. We continue to prioritize resources to enable us to deliver data from our ongoing trials."

COMMERCIAL READINESSS FOR ADP-A2M4 IN SARCOMA WITH AIM TO LAUNCH IN 2022

• Data presented at ESMO 2019 demonstrating a clear benefit of ADP-A2M4 for patients with synovial sarcoma showing:
    º  Overall response rate of 58% with 7 out of 12 evaluable patients with clinical responses
    º  Disease control rate (best overall responses of partial response or stable disease) of 92% with 11 out of 12 evaluable patients showing clinical benefit
    º  These data will be updated at CTOS on November 16^th
• Enrolling patients in SPEARHEAD-1 (Phase 2 trial in synovial sarcoma and myxoid/ round cell liposarcoma) across several leading clinical trial centers

FOCUSED ON EXECUTION IN OTHER CLINICAL TRIALS

• Dosing in the SURPASS trial with ADP-A2M4CD8 – the first next-generation trial at several clinical trial centers with data updates anticipated in 1H 2020
    º  Preclinical data show that these next-generation SPEAR T-cells may improve long term T‑cell function as well as antitumor activity
• Enrolling in Cohort 3 in the ADP-A2AFP trial in liver cancer at target doses of 5 billion SPEAR T‑cells (range 1.2 to 6 billion), after Safety Review Committee endorsed dose escalation
• Continuing enrollment in the radiation sub-study of the Phase 1 ADP-A2M4 trial
• Based on emerging translational data to be presented at SITC on November 8^th, will initiate a clinical trial combining ADP-A2M4 with a PD-1 pathway inhibitor in 2020

PRECLINICAL PROGRESS

• Continued progress with stem-cell derived allogeneic program, which is applicable to all T-cells (including both CAR-T and TCR T-cells) with data updates next year
• Initiated collaboration with Noile-Immune to develop further next-generation products

OTHER CORPORATE NEWS

Financial Results for the three-month period ended September 30, 2019

• Cash / liquidity position: As of September 30, 2019, Adaptimmune had cash and cash equivalents of $39.4 million and Total Liquidity¹ of $102.9 million.  The Company also received $15.8 million for UK R&D Tax Credits in October 2019.
   
• Revenue: Revenue for the three and nine months ended September 30, 2019 was $0.2 million and $0.4 million respectively, compared to $40.8 million and $58.0 million for the same periods in 2018. The revenue in the three and nine months ended 2019 is due to the commencement of development under the third target nominated by GSK under the Collaboration and License Agreement, whereas the development and license revenue for the same periods in 2018 was recognized due to the performance under the NY-ESO transition program and the PRAME development plan, which were completed in 2018.
   
• Research and development (R&D) expenses: R&D expenses for the three and nine months ended September 30, 2019 were $29.6 million and $77.1 million, respectively, compared to $23.5 million and $75.5 million for the same periods of 2018. The three and nine month periods ended September 30, 2019 include the impact of recognized purchase commitments for clinical materials of $5.0 million, and in process research and development payments relating to the collaboration agreements with Alpine Immune Sciences, Inc of $2.0 million in May 2019 and Noile-Immune Biotech, Inc of $2.5 million in August 2019. These increases were partially offset by a decrease in share-based compensation expense due to option forfeitures in both periods, an increase in reimbursements for research and development tax and expenditure credits in both periods, and, during the nine months ended September 30, 2019, a reduction in expenditure associated with the NY-ESO program, which was transferred to GSK on July 23, 2018.
   
• General and administrative (G&A) expenses: G&A expenses for the three and nine months ended September 30, 2019 were $10.7 million and $32.7 million respectively, compared to $10.3 million and $32.8 million for the same periods of 2018.
   
• Other income (expense), net: Other income (expense), net for the three and nine months ended September 30, 2019 was income of $0.3 million and an expense of $0.6 million respectively, compared to expenses of $2.2 million and $10.5 million for the same periods of 2018. Other income (expense), net primarily comprises unrealized foreign exchange losses, which fluctuate depending on exchange rate movements and the amount of foreign currency assets and liabilities. Management determined that, effective from July 1, 2019, an intercompany loan was of a long-term investment nature and therefore, from that date, foreign exchange differences on this intercompany loan have subsequently been reported within other comprehensive income (loss).
   
• Net (loss) income: Net (loss) income attributable to holders of the Company's ordinary shares for the three and nine month periods ended September 30, 2019 was losses of $39.3 million and $107.8 million respectively, and $(0.06) and $(0.17) per ordinary share respectively, compared to income of $5.2 million and a loss of $59.3 million respectively, and $0.01 and $(0.10) per ordinary share respectively in the same periods of 2018.      

Financial guidance

The Company believes that its existing cash, cash equivalents and marketable securities will fund the Company's current operations through the third quarter of 2020. As further detailed in the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2019, to be filed with the Securities and Exchange Commission following this earnings release, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date the financial statements are issued. The Company concluded that there are factors that raise substantial doubt about its ability to continue as a going concern for at least one year from the issuance of the September 30, 2019 quarterly condensed consolidated financial statements. In the immediate future, the Company plans to continue to prioritize and review ongoing clinical development projects and costs with the aim of focusing operations on the ADP-A2M4 SPEARHEAD-1, ADP-A2M4CD8 SURPASS, and ADP-A2AFP trials. The Company believes that a combination of targeted clinical progress together with accessing additional capital and/or cost reductions will enable the Company to continue as a going concern for the next twelve months. The Company's financial results are presented as though it would continue as a going concern.
