PHILADELPHIA and OXFORDSHIRE, United Kingdom, Feb. 25, 2021 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in cell therapy to treat cancer, today reported financial results for the fourth quarter and year ended December 31, 2020, and provided a business update.

“We are building the cell therapy company of the future for people with cancer. With our ‘2-2-5-2’ by 2025 strategic plan, we will deliver value with marketed SPEAR T-cell products starting with ADP-A2M4 for people with synovial sarcoma,” said Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer. “We completed enrollment in our SPEARHEAD-1 trial in approximately 12 months to support our first BLA, which is strong evidence of our ability to execute rapidly. We are focusing the SURPASS trial, using our next-generation ADP-A2M4CD8 product, on lung, gastroesophageal, head and neck, and bladder cancers to identify new indications to take forward to late-stage development.”

Planned 2021 data updates1

  • SPEARHEAD-1 trial with ADP-A2M4 for people with synovial sarcoma
    • June: preliminary data at American Society of Clinical Oncology (ASCO)
    • November: full update at Connective Tissue Oncology Society (CTOS)
  • SURPASS Phase 1 trial with ADP-A2M4CD8 (next-generation product targeting MAGE-A4)
    • September: update at European Society for Medical Oncology (ESMO)
  • Additional clinical updates
    • September: update at International Liver Cancer Association (ILCA) conference for ADP-A2AFP Phase 1 trial for people with liver cancer
    • October: update at American Society for Radiation Oncology (ASTRO) for radiation sub-study of the ADP-A2M4 Phase 1 trial2
    • November: ADP-A2M4 translational data update at Society for Immunotherapy of Cancer (SITC)

“2-2-5-2” by 2025 strategic plan
At an Investor Day held in November 2020, the Company outlined its “2-2-5-2” by 2025 strategic plan encompassing:

“2” - Two marketed products targeting MAGE-A4
Estimated potential addressable population in tumor types with significant MAGE-A4 expression, factored for HLA-A23, is ~39,000 patients per year in the US and EU

Durable responses in synovial sarcoma – on track to file a Biologics License Application (BLA) for ADP-A2M4 in 2022

  • The first commercial opportunity for SPEAR T-cells targeting MAGE-A4 will be in synovial sarcoma with plans to file a BLA in the US in 2022
  • In 2020, the Company received positive endorsements from regulatory authorities with Regenerative Medicine Advanced Therapy (RMAT) designation and Orphan Drug Designation (ODD) in the US, and access to PRIority MEdicines (PRIME) regulatory support and ODD in the EU
  • Data from the Phase 1 trial with ADP-A2M4 (presented at CTOS 2020)
    • In 16 patients with synovial sarcoma, there was an Overall Response Rate of 44% and a Disease Control Rate of 94%
    • Responses were durable with a median duration of response of 28 weeks with ongoing responses beyond 72 weeks in two patients (median overall survival had not been reached)
    • These data are considerably superior4 to response rates observed with available second line therapies in synovial sarcoma

SURPASS-2 in esophageal and esophagogastric junction (EGJ) cancers in 1H 2021

  • The Company will initiate a Phase 2 trial, SURPASS-2, with ADP-A2M4CD8 (next-generation SPEAR T-cells targeting MAGE-A4 that co-express CD8α intended to increase potency) for patients with esophageal or EGJ cancers in 1H 2021
  • SURPASS-2 is supported by encouraging data from the Phase 1 SURPASS trial (presented at SITC 2020) with one confirmed partial response (PR) in a patient with EGJ cancer and tumor reductions in two additional patients (1 with esophageal and 1 with EGJ cancer)
  • The trial will be conducted at multiple centers in North America and the EU, and is intended to enroll 45 people with esophageal or EGJ cancers to be treated with doses up to 10 billion SPEAR T-cells
  • The Company also presented preclinical data at SITC 2020 indicating that AKT inhibition during the manufacture of SPEAR T-cells results in a more consistent expansion and phenotype of the final product. This process is currently being used for the Phase 1 SURPASS trial.

“2” - Two additional BLAs for SPEAR T-cell products

  • Adaptimmune’s Phase 1 SURPASS trial with ADP-A2M4CD8 continues to enroll patients, focusing on lung, gastroesophageal, head and neck, and bladder cancers – indications for which the Company has reported responses or signs of efficacy with its MAGE-A4 targeted products
  • In 2020, Adaptimmune initiated SPEARHEAD-2 with its first-generation SPEAR T-cells targeting MAGE-A4 in combination with pembrolizumab for people with head and neck cancers
  • The Phase 1 trial with ADP-A2AFP for people with liver cancer is ongoing. As presented at ILC 2020, nine patients were treated as of the data cut-off and best responses were:
    • One patient with a complete response, one with stable disease (SD), and two with progressive disease (PD) among the four patients who received ~5 billion or more SPEAR T-cells
    • Five patients with SD who received doses of 100 million and 1 billion SPEAR T-cells in the first two dose cohorts

“5” - Five new autologous products in the clinic

  • Adaptimmune has a deep preclinical pipeline from which it expects to bring five new products into the clinic.
  • These include multiple possibilities for next-generation autologous SPEAR T-cells such as:
    • ADP-A2AFP SPEAR T-cells co-expressing CD8α
    • ADP-A2M4 SPEAR T-cells co-expressing IL-7, IL-15, dnTGFβ, and/ or PDE7
    • Enhancing SPEAR T-cells with IL-7 for proliferation and survival and CCL19 for migration into tumor in collaboration with Noile-Immune Biotech, Inc.
    • Enhancing SPEAR T-cells using transmembrane and surface immunoregulatory mechanisms with Alpine Immune Sciences, Inc.
  • The Company is also developing new products, including:
    • Expanding into HLAs beyond HLA-A2 to increase the addressable patient population
    • HLA-independent TCR (HiT) candidates for multiple targets including GPC3
    • A new program for next-generation TILs co-expressing IL-7 in melanoma in collaboration with leading TIL therapy center (CCIT, Denmark)

“2” - Two allogeneic products in the clinic

  • In January 2020, Adaptimmune announced it had entered into an agreement to co-develop and co-commercialize stem-cell derived allogeneic cell therapies with Astellas
    • The first target nominated is a HiT targeting mesothelin
  • At ASGCT 2020, Adaptimmune presented data with evidence of its allogeneic platform demonstrating differentiation of functional T-cells from human-induced pluripotent stem cells (hiPSCs) that can kill MAGE-A4 expressing target cells in vitro –targeted to become the Company’s first allogeneic product in the clinic

Corporate updates from 2020

  • Despite the impact of the COVID-19 pandemic on the biotechnology industry, Adaptimmune continued to see improved enrollment in its clinical trials
  • In Q1, the Company received an upfront payment of $50 million from Astellas. The Company is also entitled to receive research funding of up to $7.5 million per collaboration target per year
  • Underwritten public offering in Q1 generated net proceeds of approximately $90 million
  • Underwritten public offering in Q2 generated net proceeds of approximately $244 million

Financial Results for the fourth quarter and year ended December 31, 2020

  • Cash / liquidity position: As of December 31, 2020, Adaptimmune had cash and cash equivalents of $56.9 million and Total Liquidity5 of $368.2 million.

  • Revenue: Revenue for the fourth quarter and year ended December 31, 2020 was $1.5 million and $4.0 million, respectively, compared to $0.7 million and $1.1 million for the same periods in 2019. The increase was due to revenue arising under the collaboration agreement with Astellas, which was entered into in January 2020.

  • Research and development (R&D) expenses: R&D expenses for the fourth quarter and year ended December 31, 2020 were $25.8 million and $91.6 million, respectively, compared to $20.4 million and $97.5 million for the same periods in 2019. R&D expenses in the year ended December 31, 2019 included the accrual of a purchase commitment and higher costs for in-process research and development; excluding the impact of these, research and development expenses have increased as the Company progresses development of its cell therapies.

  • General and administrative (G&A) expenses: G&A expenses for the fourth quarter and year ended December 31, 2020 were $13.2 million and $45.8 million, respectively, compared to $10.7 million and $43.4 million for the same periods in 2019. The increase in G&A expenses was due to an increase in general corporate costs, including professional fees and insurance.

  • Net loss: Net loss attributable to holders of the Company’s ordinary shares for the fourth quarter and year ended December 31, 2020 was $36.6 million and $130.1 million ($(0.15 per ordinary share), compared to $29.4 million and $137.2 million ($(0.22) per ordinary share) for the same periods in 2019.
