"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) (Free ASCO Whitepaper)
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) (Free ESMO Whitepaper)
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) (Free SITC Whitepaper)
"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 (Free SITC Whitepaper) 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 (Free SITC Whitepaper) 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 (Free ASGCT Whitepaper) 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

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.
