EDINBURGH, Scotland, Dec. 20, 2024 /PRNewswire/ -- TC BioPharm (Holdings) PLC ("TC BioPharm" or the "Company") (NASDAQ: TCBP) a clinical-stage biotechnology company developing platform allogeneic gamma-delta T cell therapies for cancer and other indications, today announced 3 patients have now completed the full-dose regimen in the ACHIEVE Phase 2b trial in the UK with no drug-related Adverse Events seen in any of the restart patients.

The ACHIEVE UK clinical trial is an open-label, phase II study designed to evaluate the efficacy and effectiveness of TCB008 in patients with AML or MDS/AML, with either refractory or relapsed disease.

To date, 10 patients have received their first dose, 9 patients have received their second dose, 4 patients have received their third dose, and 3 patients have received their fourth and final dose. 9 out of 10 patients recruited to date are in Cohort A, representing relapsed/refractory patients who have been unable to attain remission. One patient has been enrolled into Cohort B, representing patients who have attained remission following prior treatment yet continue to have a detectable residual disease. The patient enrolled in Cohort B received their fourth and final dose in November 2024. Initially, 14 patients are planned to be recruited into Cohort A and Cohort B and, following confirmation of study endpoints, a further 10 patients will be recruited into each cohort, giving a total of 48 patients.

The preliminary safety data shows that the 5mL dose of TCB008 is well tolerated, with no drug-related Adverse Events. These data outputs remain aligned with TCB008's safety profile, in support of the ACHIEVE study safety objectives and endpoints.

"Recruitment into the ACHIEVE trial has been an overwhelming success in 2024," said Alison Bracchi, Executive Vice President of Clinical Operations. "Currently, more than half of the patients in the initial stage of Cohort A have been recruited into the ACHIEVE study. We're also thrilled to observe the progression of Cohort B. This expedited rate of recruitment has been accomplished in less than 5 months due to the hard work and dedication of both the ACHIEVE Clinical sites and the entire TCBP team. The TCBP team and I look forward to continued success with recruitment and preliminary data from the ACHIEVE study in 2025."

"As we progress with Cohort B, there is the potential for an expedited review given these patients' stage and disease expression," said Bryan Kobel, CEO of TC BioPharm. "We believe minimal residual disease represents a high opportunity for TCB008 to be extremely impactful. We could see a response indicating high responsiveness in fewer than the currently proposed cohort size. At this trial stage, we are still collating data, due to the regulatory framework, we cannot yet comment on efficacy specifically, but we are encouraged to see patients completing the dosing regimen successfully and without any safety issues. Our immediate clinical focus will be high recruitment on Cohort B in 2025 and completing the Cohort A patient set for data review. We appreciate the hard work of the King's College Hospital and our fantastic investigator group including Dr. Victoria Potter, and Dr. Emma Nicholson. The recruitment has been exceptional and we look forward to continuing our work with them in 2025."
