PHILADELPHIA and OXFORD, United Kingdom, May 06, 2021 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq: ADAP), a leader in cell therapy to treat cancer, today reported financial results for the first quarter ended March 31, 2021 and provided a business update.

“We will present initial data at ASCO from our SPEARHEAD-1 trial that will support BLA submission in 2022. We have seen good enrollment in the SURPASS and ADP-A2AFP trials and will present data later this year,” said Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer. “We continue to deliver against our ambitions laid out in our 2-2-5-2 strategic plan to bring products forward for clinical development and launch. At ASGCT next week, we will present preclinical data from our first HiT product targeting mesothelin. Results indicate that this HiT works as well or better than similar cell therapy constructs targeting the same antigen in in vitro killing assays as well as an animal model.”

Upcoming confirmed data updates

• Data from the Company’s HiT mesothelin program, being co-developed with Astellas, to be presented at the American Society of Gene & Cell Therapy (ASGCT), in a poster presentation that will be available on the conference’s website May 11 at 8:00 a.m. EDT
  
  
  • Important progress towards achievement of preclinical pipeline milestones laid out in the Company’s strategic five-year “2-2-5-2” product development plan presented at Investor Day in November 2020
  • Preclinical data validate that human T-cells expressing a TCR that targets mesothelin independent of peptide-HLA recognition, can kill human tumor cells
  • Presentation will include animal model data that demonstrate superiority of the Company’s HiT targeting mesothelin over a comparator T-cell therapy construct targeting the same antigen in an in vivo tumor xenograft study
  • This product was nominated by Astellas as the first candidate under the agreement to co-develop and co-commercialize iPSc (stem-cell) derived allogeneic CAR-T and TCR T-cell therapies
    
    
• Oral presentation of initial data from the SPEARHEAD-1 trial with afamitresgene autoleucel (afami-cel, formerly ADP-A2M4) for people with synovial sarcoma and MRCLS at the American Society of Clinical Oncology (ASCO) on June 4^th during the Sarcoma Session starting at 1:30 p.m. EDT (abstract # 11504)
  
  
  • At time of data cut-off for the abstract¹, 32 patients had received afami-cel. Twenty-five patients were evaluable for preliminary efficacy and 7 patients had insufficient follow-up
  • On May 19, 2021 at 5:00 p.m. EDT, abstracts will be released on ASCO's Meeting Library and the Company plans to issue a press release²
  • The Phase 2 SPEARHEAD-1 trial was initiated after promising results from the Phase 1 trial showed durable responses with afami-cel in synovial sarcoma with confirmed responses in 44% of patients, disease control rate of 94%, and median duration of response of 28 weeks presented at CTOS 2020
  • The Company will submit an abstract with a further update for consideration at CTOS 2021
    

Planned data updates ³

• SURPASS Phase 1 trial with ADP-A2M4CD8 (next-generation product targeting MAGE-A4) at European Society for Medical Oncology (ESMO) in September
• ADP-A2AFP Phase 1 trial for people with liver cancer at the International Liver Cancer Association (ILCA) in September
• Radiation sub-study of the ADP-A2M4 Phase 1 trial at American Society for Radiation Oncology (ASTRO) in October
