EDINBURGH, Scotland, Sept. 13, 2022 /PRNewswire/ -- TC Biopharm (Holdings) PLC ("TC Biopharm" or the "Company") (NASDAQ:TCBP) (NASDAQ:TCBPW), a clinical stage biotechnology company developing platform allogeneic gamma-delta T cell therapies for cancer today announced that it has received approval from the UK regulatory body MHRA to apply an 18-month extrapolated shelf life to its current allogeneic cell therapy product, OmnImmune.

This award enables TC BioPharm to ship and store sufficient product which can then be held cryopreserved at clinical sites to fulfill the requirements not only for its current Advanced Myeloid Leukemia trial ACHIEVE, but also for future clinical trials and eventually commercial treatment of patients. Additionally, TC BioPharm's in-house quality control department will continue to gather data in order to extend the shelf-life of OmnImmune.

"The approval received from the MHRA for our frozen product is another very important piece of a complex jigsaw. It is indeed a further step towards the achievement of a platform to deliver truly off-the-shelf products in the cell therapy space. This milestone is a result of an incredible concerted effort from all the departments within TCB, including Product Development, Quality Control and Assurance, Production and Clinical. It is an exciting time to be working in this sector and I feel incredibly privileged and proud to be part of this amazing team at TC Biopharm."

Bryan Kobel, CEO, commented, "This MHRA approval of our freeze/thawed protocol for an 18-month shelf life is an encouraging step forward in TC BioPharm's developmental trajectory and further validation of the continuous effort and forward thinking of our development team. We are extremely pleased to receive MHRA approval for our Freeze/Thawed product, OmnImmune, the first freeze/thawed gamma delta product in clinical trials. Being able to ship frozen gamma-delta T cells and deliver them clinics all around the world for storage and use in clinical trials as well as commercial treatment increases our economies of scale and our efficiency."

Kobel continued, "This approval brings OmnImmune truly to the forefront as an "off the shelf" cell therapy, with the clinician's ability to bring product from the storage facility to the specialty pharmacy for thawing and deliver the therapeutic to the patient in a short window of time. We look forward to progressing our clinical trials in AML as well as other blood cancers and continue to evaluate partnering opportunities for our allogeneic gamma delta platform and advance our modified CAR gamma delta program."
