BT-001

BT-001 is a multifunctional oncolytic virus

encoding for an anti-CTLA4 antibody and GM-CSF

BT-001 is the first oncolytic virus from Invir.IO™ and is optimized to act as a Trojan horse.

Two specific “weapons” have been integrated into the Vaccinia viral DNA: an anti-CTLA4 antibody, which was developed by BioInvent, and the cytokine GM-CSF, which triggers the body’s immune response.

Collaboration agreement

BioInvent and Transgene are together creating a novel armed oncolytic virus that will be able to infect and selectively replicate within the tumor, inducing cancer cell destruction, and to elicit a strong immune response that is further enhanced by the local expression of the immune checkpoint inhibitor and the cytokine. This novel oncolytic virus is expected to deliver better treatment outcomes with an improved safety profile as the patient is not exposed to the the anti-CTLA4 antibody at a systemic level.

Transgene and BioInvent have entered into a clinical trial collaboration and supply agreement with MSD, a tradename of Merck & Co., Inc., Rahway, NJ., USA, to evaluate the combination of the oncolytic virus BT-001 in combination with MSD’s anti-PD-1 checkpoint therapy KEYTRUDA® (pembrolizumab) in a Phase I/IIa clinical trial for the treatment of patients with solid tumors.”
