PHILADELPHIA and OXFORD, United Kingdom, Nov. 04, 2021 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq: ADAP), a leader in cell therapy to treat cancer, today reported financial results for the third quarter ended September 30, 2021, and provided a business update.

“We made excellent progress in Q3. The SURPASS data presented at ESMO, the start of our first Phase 2 trial with ADP-A2M4CD8 next-gen SPEAR T-cells, and the announcement of our strategic collaboration with Genentech all support our 2-2-5-2 strategy,” said Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer. “Looking ahead, the SPEARHEAD-1 data that we will present at the CTOS meeting will support a BLA for afami-cel in 2022. Next year, we will initiate a Phase 2 trial with ADP-A2M4CD8 for patients with ovarian cancer and evaluate the combination of this next-generation therapy with checkpoint inhibitors. All these activities will strengthen our leadership position with our MAGE-A4 franchise.”

Highlights from clinical data updates in Q3
SURPASS Phase 1 trial at the European Society for Medical Oncology (ESMO) virtual meeting (August 2, 2021 data cut-off)

  • Initial efficacy and durability data were encouraging with responses across five different solid tumors (ovarian, head and neck, esophagogastric junction, bladder, and synovial sarcoma); refer to the press release for more detail
  • The overall response rate was 36% and the disease control rate was 86%, per Investigator Review
  • There was a complete response reported in a patient with ovarian cancer, which remains ongoing at 6 months post-infusion
  • Eleven patients remain on study. Of the 8 responders, 5 remain in response with some remaining progression free >24 weeks
  • The safety profile of the next-generation ADP-A2M4CD8 cell therapy was acceptable
  • Data confirm preclinical observations that the enhanced TCR interaction with next-generation ADP-A2M4CD8 SPEAR T-cells results in a more potent product
  • Safety and efficacy, will continue to be evaluated in the ongoing SURPASS trial, which is enrolling eligible patients with gastroesophageal, head and neck, lung, bladder, and ovarian cancers

Further indications for late-stage clinical development

  • Initiated a Phase 2 trial, SURPASS-2, for patients with esophageal and EGJ cancers
  • Next year, the Company will initiate SURPASS-3, a Phase 2 trial with ADP-A2M4CD8 for people with ovarian cancer based on the initial responses seen in the SURPASS Phase 1 trial (presented at ESMO 2021)
  • The Company is planning to evaluate ADP-A2M4CD8 in combination with a checkpoint inhibitor.
  • The SPEARHEAD-2 trial has now closed to enrollment

ADP-A2AFP Phase 1 trial in liver cancer at the International Liver Cancer Association (ILCA) meeting

  • As of the April 5, 2021 data cut-off, antitumor activity, with one complete response, sustained decreases in serum AFP, and best overall response of stable disease observed in 6 patients with liver cancer, indicating that ADP-A2AFP is an active product in hepatocellular carcinoma (HCC); refer to the press release for more detail
  • ADP-A2AFP has been associated with an acceptable safety profile with doses up to 10 billion transduced cells
  • The trial is approaching 25 patients treated, which is anticipated to be sufficient to assess the trial objectives
  • The Company will close screening by the end of 2021, and focus on other preclinical programs for liver cancer

Preclinical pipeline updates
Allogeneic platform

  • Adaptimmune intends to file its first IND for an allogeneic therapy targeting MAGE-A4 (wholly owned) in 2023
  • The Company announced a strategic collaboration with Genentech to research, develop, and commercialize allogeneic T-cell therapies. The Agreement became effective following expiry of all applicable waiting periods under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976, with Adaptimmune set to receive the $150 million upfront payment
  • This strategic collaboration builds on Adaptimmune’s cell therapy expertise and progress with its allogeneic platform, which was highlighted during a live virtual event held in September
  • The 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


  • The Company plans to open a new facility at Milton Park, Oxfordshire, UK, by the end of 2022, where allogeneic products for clinical trials will be manufactured

Financial Results for the three and nine months ended September 30, 2021

Financial Results for the three and nine months ended September 30, 2021

  • Cash / liquidity position: As of September 30, 2021, Adaptimmune had cash and cash equivalents of $42.9 million and Total Liquidity2 of $240.1 million. In addition, under the terms of the Genentech agreement, Adaptimmune is entitled to receive $150 million as an upfront payment, which is anticipated to be received in the fourth quarter of 2021.
  • Revenue: Revenue for the three and nine months ended September 30, 2021 was $1.2 million and $4.7 million, respectively, compared to $1.2 million and $2.5 million for the same periods in 2020. Revenue has increased primarily due to an increase in development activities under our collaboration arrangements.
  • Research and development (R&D) expenses: R&D expenses for the three and nine months ended September 30, 2021 were $28.2 million and $81.6 million, respectively, compared to $24.1 million and $65.8 million for the same periods in 2020. R&D expenses increased due to an increase in the number of employees engaged in research and development, increases in costs related to the development of a companion diagnostic assay, and expansion of our clinical trials. These increases were partially offset by an increase in reimbursements receivable for research and development tax and expenditure credits.
  • General and administrative (G&A) expenses: G&A expenses for the three and nine months ended September 30, 2021 were $15.1 million and $42.5 million, respectively, compared to $13.0 million and $32.6 million for the same periods in 2020 due to increases in employee-related costs, share-based compensation expense, and professional fees.
