PHILADELPHIA and OXFORDSHIRE, United Kingdom, Aug. 01, 2019 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today reported financial results for the second quarter ended June 30, 2019 and provided a business update.

James Noble, Adaptimmune CEO said: “I have spent twenty years in the field of T-cell receptors and am convinced that they will have an important role in treating patients. We have already seen compelling data in sarcoma with ADP‑A2M4 and have recently started a trial with a next-generation SPEAR T-cell and a combination trial with low-dose radiation to improve the depth and durability of responses. It is my final pleasure as CEO to be handing over to Adrian. I know that he will do an excellent job in taking the Company through its next evolution towards commercialization. The changes that he is already introducing and the plans for the future will bring energy and focus to the tasks ahead, accelerating execution across the Company.”

Adrian Rawcliffe, incoming Adaptimmune CEO said: “Looking forward, I intend to further focus the Company on increasing the pace of execution, which has already enabled us to initiate our first late-stage trial: SPEARHEAD-1, our first next-gen trial: SURPASS, and the low-dose radiation sub-study in recent weeks. In addition, we will strengthen our capabilities to be ready to launch our first product in 2022. Finally, we intend to leverage the state-of-the-art integrated capabilities that we have built in research, development and supply, to apply them in cell therapy more broadly.”

Clinical programs

• Initiated Phase 2 SPEARHEAD‑1 trial with ADP-A2M4 in synovial sarcoma and myxoid/ round cell liposarcoma patients
• Initiated SURPASS trial with ADP-A2M4CD8 – the first next-generation trial with SPEAR T-cells
  • Preclinical data show that these next-generation SPEAR T-cells may improve long term T‑cell function as well as antitumor activity
• Initiated low-dose radiation sub-study of ADP-A2M4 Phase 1 trial in collaboration with the MD Anderson Cancer Center
  • There is emerging data showing that low-dose radiation could enhance T-cell tumor trafficking and responses
• Focusing efforts on ADP-A2M4, ADP-A2M4CD8, and ADP-A2AFP, with enrollment in the ADP‑A2M10 trials closing by the end of 2019
• Will provide clinical updates on all ongoing clinical trials at medical conferences
  • At ESMO 2019, Brian Van Tine, MD, PhD of Washington University in St. Louis will present an oral presentation titled “ADP-A2M4 (MAGE-A4) in patients with Synovial Sarcoma” on September 30, 2019
• Since our last clinical update, the Company has reported serious adverse events (SAEs) in three patients
  • All three patients received the highest lymphodepletion regimen: fludarabine (30mg/m²/day for 4 days) and cyclophosphamide (1800 mg/m²/day for 2 days)
  • One patient in each of the ADP-A2M10 and ADP-A2M4 trials had reports of severe prolonged pancytopenia. Both patients subsequently died of complications.
  • In the third patient (in the ADP-A2M4 trial) there was one report of Grade 3 neurotoxicity. The patient subsequently died of a stroke that the Company believes was unrelated to SPEAR T-cell therapy.
  • Subsequently, the protocols for all ADP-A2M4 and ADP-A2M10 trials have been amended to include changes in eligibility criteria and reversion to the previously used lower dose of cyclophosphamide
  • These protocol changes have been communicated to the FDA

Commercial readiness

• Working with Vineti as part of Adaptimmune’s strategy to deliver products through clinical trials and into scaled-up production post approval. Vineti is the first cloud-based software platform to efficiently take T-cell therapies through clinical trials and into mainstream medicine at commercial scale.
