Transgene and BioInvent Receive IND Approval from the U.S. FDA for BT-001, a Novel Oncolytic Virus for the Treatment of Solid Tumors - Seite 2

“We are pleased to receive IND approval for this Phase I/IIa clinical trial of BT-001, which is BioInvent’s fourth clinical program. This unique oncolytic virus has very exciting potential as it combines multiple mechanisms of action and anti-cancer properties, and we are looking forward to developing it further with our partners at Transgene,” said Martin Welschof, CEO of BioInvent.

The Phase I trial is divided into two parts. Part A will enroll up to 36 patients with metastatic/advanced solid tumors. Patients will receive single agent, intra-tumoral administrations of BT-001. Part B will explore the combination of intra-tumoral injections of BT-001 with the standard treatment regimen of pembrolizumab in 12 patients. The Phase IIa part of the trial will evaluate BT-001-based combination regimen in several patient cohorts with different tumor types. These expansion cohorts will offer the possibility of exploring the activity of this approach to treat other malignancies not traditionally addressed with this type of treatment.

About BT-001

BT-001 is a novel oncolytic virus developed with Transgene’s Invir.IO platform. Invir.IO’s viruses are based on the patented large capacity Vaccinia virus Copenhagen strain genetically modified with the double deletion TK^-RR^-. This optimization enhances the safety profile of the virus.

BT-001 is engineered to encode both a highly differentiated Treg depleting anti-CTLA4 antibody and the human GM-CSF cytokine. The recombinant antibody recognizing human CTLA4 was generated by BioInvent’s proprietary n-CoDeR/F.I.R.S.T platforms. The use of an oncolytic virus to deliver the anti-CTLA4 locally and selectively in the tumor microenvironment allows high intratumoral concentrations of both transgenes eliciting a stronger and more effective antitumor response, by reducing systemic exposure to a very low level.

Preclinical data have shown that BT-001 has potential for broad single agent activity, and that selective tumor-localized delivery of anti-CTLA4 may allow for a better tolerated, sustained and more effective combination therapy with antibodies targeting the PD-1/PDL1 axis.

The scientific and clinical development of the oncolytic virus candidate BT-001 is a 50/50 collaboration between BioInvent and Transgene.
