TC BioPharm Receives MHRA Approval for 18-Month Extrapolated Shelf-Life of Allogeneic Cell Therapy Product, OmnImmune®

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."

“The approval received from the MHRA for our frozen product is another very important piece of a complex jigsaw,” said Emilio Cosimo, Director of Product Development at TC BioPharm. “It is indeed a further step towards the achievement of a platform to deliver truly off-the-shelf products in the cell therapy space.
