BioNTech SE and Kite announced the two companies have entered into a purchase agreement for BioNTech to acquire Kite’s solid tumor neoantigen T cell receptor (TCR) R&D platform and clinical manufacturing facility in Gaithersburg, MD. The acquired Gaithersburg facility will provide production capacity to support clinical trials in the United States and will complement BioNTech’s existing cell therapy manufacturing facility in Idar-Oberstein, Germany. The facility will support the development of BioNTech’s expanding pipeline of novel cell therapies, including cancer product candidates based on its CAR-T Cell amplifying mRNA vaccine (CARVac) and NEOSTIM platforms as well as the newly acquired individualized neoantigen TCR program. All Kite employees at the Gaithersburg facility will be offered employment with BioNTech prior to the date of closing. To support its growing cell therapy pipeline, BioNTech plans to further invest in the site including hiring additional personnel. Under the terms of the agreement, Kite will receive a one-time upfront payment from BioNTech to purchase Kite’s indiviualized solid tumor neoantigen TCR discovery platform as well as the Gaithersburg R&D and clinical manufacturing facility. Financial terms were not disclosed. Kite’s new manufacturing facility in Frederick, MD for commercial production of CAR T-cell therapy is not part of the purchase agreement. TCR therapy is a type of cellular immunotherapy designed to redirect the patient’s immune system in order to recognize and target tumors. In contrast to CARs that recognize antigens on the cell surface, TCR therapy involves engineering an individual’s T cells to express TCRs that can recognize peptide fragments from both intracellular and extracelluar antigens. As a result, complex TCR therapies may be more effective in the treatment of solid tumors. Neoantigens are immune targets derived from somatic mutations displayed by cancer cells offering the potential for more targeted anti-tumor activity. Kite’s neoantigen TCR platform enables the development of individualized TCR therapies that are custom designed to target individual neoantigens on a patient’s tumor. This program builds and further extends BioNTech’s leadership in individualized neoantigen targeting programs such as BNT122 (iNeST) and BNT221 (NEOSTIM). Cowen & Company LLC acted as financial advisor to Kite for this transaction.
