PHILADELPHIA and OXFORDSHIRE, United Kingdom, March 14, 2022 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq: ADAP), a leader in cell therapy to treat cancer, today reported financial results for the fourth quarter and full year ended December 31, 2021, and provided a business update.

“We are focused on four things in 2022: filing our first BLA, building our MAGE-A4 franchise, scaling up our manufacturing capabilities, and making progress with our allogeneic platform,” said Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer. “Last year, we delivered major milestones of our ‘2-2-5-2’ strategic plan. SPEARHEAD-1 met its primary endpoint and we identified further indications for late-stage development with our next-gen SPEAR T-cells targeting MAGE-A4. Furthermore, not only did we enter a strategic collaboration with Genentech, but we also made tremendous progress with our wholly owned allogeneic therapy targeting MAGE-A4, which is on-track for an IND in 2023.”

Progress with the Company’s “2-2-5-2” strategic plan to be delivered by 2025
“2” marketed SPEAR T-cell products targeting MAGE-A4
Roadmap to BLA submission for afami-cel¹ in 2022 (first-generation product targeting MAGE-A4)

• Advanced/metastatic synovial sarcoma is a rare and clinically challenging disease, with no clear standard of care after progression following chemotherapy, with reported response rates with second line therapies of 18% or lower
• SPEARHEAD-1 has met its primary endpoint²
• As of the data cut-off of September 1, 2021 (CTOS), the overall response rate (ORR) per Independent Review was 34% (36% in patients with synovial sarcoma and 25% for patients with myxoid/ round cell liposarcoma [MRCLS])
• Afami-cel continues to show a favorable benefit:risk profile with more than 100 patients treated to date across multiple trials
• Cohort 1 of the SPEARHEAD-1 trial has completed, and treatment in Cohort 2 initiated in 2021
• Pediatric plans agreed with regulatory agencies
• Adaptimmune is commencing preparation of the BLA and targeting a BLA submission to the US Food and Drug Administration (FDA) in Q4 2022
  

Further indications for late-stage clinical development for SPEAR T-cells targeting MAGE-A4

• Initiated recruitment in the Phase 2 SURPASS-2 trial for people with esophageal and esophagogastric junction (EGJ) cancers
• Initiating the Phase 2 SURPASS-3 trial for people with ovarian cancer in 2022

“2” additional BLAs for SPEAR T-cell products targeting MAGE-A4
Phase 1 SURPASS trial with next-generation ADP-A2M4CD8 SPEAR T-cells targeting MAGE-A4

• Overall response rate of 36% with a complete response in ovarian cancer, and partial responses in ovarian, head and neck, EGJ, bladder, and synovial sarcoma cancers (ESMO 2021)
• Most patients experienced antitumor activity with a disease control rate of 86% (ESMO 2021)
• The benefit:risk profile of ADP-A2M4CD8 cell therapy remains favorable
• The SURPASS trial continues to enroll, focusing on people with gastroesophageal, head and neck, lung, bladder, and ovarian cancers
• Combination with a checkpoint inhibitor to be started this year
• Data confirmed preclinical observations that the enhanced TCR interaction in ADP-A2M4CD8 results in a more potent product (SITC 2021)

Other clinical updates

• Closed enrollment in the SPEARHEAD-2 trial investigating afami-cel in combination with a checkpoint inhibitor for people with head and neck cancer in 2021
• Presented data from the radiation sub-study of the completed Phase 1 trial with afami-cel (SITC 2021), which closed to enrollment in 2021
• Reported clinical benefit to people with liver cancer from the Phase 1 ADP-A2AFP trial (ILCA 2021)
  • This trial closed to screening in 2021
  • The Company continues to focus development on new cell therapies to target liver cancer
    

“5” autologous products in the clinic
Preclinical pipeline update

• Filed a clinical trial application (CTA) for tumor-infiltrating lymphocytes (TILs) incorporating IL-7 (a potent stimulator of T-cell proliferation and survival) in collaboration with the Center for Cancer Immune Therapy (CCIT, a leading TIL center) in Denmark, with the intent to initiate a single-center clinical trial in 2022
• Planning to initiate a Phase 1 trial in multiple indications with a new next-generation SPEAR T-cell targeting MAGE-A4, being developed in collaboration with Noile-Immune Biotech Inc., that incorporates IL-7 and CCL19 (to increase migration of SPEAR T-cells into tumors)
• Adaptimmune continues to develop TCRs to additional HLAs and new targets, as well as further next-generation approaches
  

“2” allogeneic products in the clinic
Allogeneic pipeline update

• Wholly owned allogeneic platform on track for planned IND submission in 2023 for first product targeting MAGE-A4
• Announced a strategic collaboration with Genentech to research, develop, and commercialize allogeneic T-cell therapies
  • Collaboration covers the research and development of “off-the-shelf” cell therapies for up to five shared cancer targets and the development of a novel allogeneic personalized cell therapy platform
  • Adaptimmune received $150 million upfront payment under the terms of the agreement
• First preclinical data presented from the Company’s mesothelin HLA-independent TCR (HiT) program, which is being co-developed with Astellas, demonstrating antigen-specific tumor cell killing in vitro and complete tumor regression in an animal model (ASGCT 2021).
• The animal model also demonstrated that Adaptimmune’s HiT T-cells targeting mesothelin outperformed a comparator TRuC construct (ASGCT 2021)
• Second target nominated for allogeneic product development in collaboration with Astellas
  

Patient supply

• To date, Adaptimmune has successfully manufactured hundreds of autologous batches in-house at its Navy Yard facility (Philadelphia, PA) across multiple products and tumor types
• Work underway at Navy Yard to scale up GMP manufacturing to meet commercial and clinical trial patient supply demands
• Started construction of a new cell manufacturing facility dedicated to allogeneic therapies in the UK, planned to be opened later this year
• Continued improvement of manufacturing processes including addition of an AKT inhibitor (AKTi). Data demonstrate that addition of AKTi during the ex vivo T-cell expansion phase of manufacturing provides further proliferative potential and enhanced memory phenotype of next-gen SPEAR T-cells (SITC 2021)

Corporate

• The Company appointed Cintia Piccina as its Chief Commercial Officer
  

Financial Results for the fourth quarter and year ended December 31, 2021

• Cash / liquidity position: As of December 31, 2021, Adaptimmune had cash and cash equivalents of $149.9 million and Total Liquidity³ of $369.6 million, compared to $56.9 million and $368.2 million, respectively, as of December 31, 2020.
• Revenue: Revenue for the fourth quarter and year ended December 31, 2021 was $1.4 million and $6.1 million, respectively, compared to $1.5 million and $4.0 million for the same periods in 2020.

¹ Afamitresgene autoleucel “afami-cel” (formerly ADP-A2M4)
² The primary endpoint is evaluated using a one-sided exact-based Clopper-Pearson 97.5% confidence interval (CI). Because the lower bound of the CI exceeds the response rate reported with historical second line therapy(ies) (18%), the trial has met the pre-specified threshold for demonstrating efficacy.
³ Total liquidity is a non-GAAP financial measure, which is explained and reconciled to the most directly comparable financial measures prepared in accordance with GAAP below
