STRASBOURG, France & LUND, Sweden--(BUSINESS WIRE)--
Regulatory News:
Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapeutics against cancer, and BioInvent International AB (“BioInvent”) (Nasdaq Stockholm: BINV), a biotech company focused on the discovery and development of novel and first-in-class immune-modulatory antibodies for cancer immunotherapy, today announce that the first patient of the Phase I part B clinical trial evaluating the combination of BT-001 and MSD’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) has been dosed.
The Phase I Part B of the trial explores repeated intra-tumoral injections of BT-001 in combination with intravenous infusions of KEYTRUDA. Transgene and BioInvent plan to enroll a minimum of 12 patients with metastatic or advanced solid tumors, including melanoma. In accordance with our clinical trial and supply agreement, KEYTRUDA is being supplied by MSD (a tradename of Merck & Co., Inc., Rahway, NJ, USA). Trial endpoints include safety, evaluation of efficacy, and assessment of immune changes in the tumor microenvironment.
Transgene and BioInvent are co-developing BT-001, an oncolytic virus designed using Transgene’s Invir.IO® platform encoding BioInvent’s differentiated anti-CTLA-4 antibody and human GM-CSF cytokine to elicit a strong and effective anti-tumoral response. The drug is currently being evaluated against solid tumors in a Phase I/IIa clinical trial as a single agent and in combination with the PD-1 checkpoint inhibitor KEYTRUDA.
The inclusion of the last patient in Part B of the study is expected in H1 2024.
Previously reported Phase I data confirmed the mechanism of action of BT-001 as a single agent and demonstrated first signs of anti-tumoral activity.
Dr. Martin Welschof, CEO of BioInvent and Dr. Alessandro Riva, Chairman and CEO of Transgene, added: “By combining BT-001 with pembrolizumab, we are building upon the promising data generated by BT-001 as a single agent. Targeting the PD1/PD-L1 pathway in addition to BT-001’s mechanism of action is expected to further stimulate and restore the patient’s immune system, which should result in improved antitumoral activity and patient outcome. We are thrilled to enter this new phase of the development of the novel oncolytic virus BT-001 and further demonstrate its potential in combination with a reference treatment.”

About the trial
The ongoing Phase I/IIa (NCT: 04725331) study is a multicenter, open label, dose-escalation trial evaluating BT-001 as a single agent and in combination with pembrolizumab (anti-PD-1 treatment). Patient inclusions are ongoing in Europe (France, Belgium) and the trial has been authorized in the US.
This Phase I is divided into two parts. In part A, patients with metastatic/advanced tumors received single agent, intra-tumoral administrations of BT-001. Part B is exploring intra-tumoral injections of BT-001 in combination with KEYTRUDA. In this part, KEYTRUDA is being provided to the trial by MSD (a tradename of Merck & Co., Inc., Rahway, NJ, USA).
The Phase IIa will evaluate the combination regimen in several patient cohorts with selected 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 an oncolytic virus generated using Transgene’s Invir.IO® platform and its patented large-capacity VVcopTK-RR- oncolytic virus, which has been engineered to encode both a Treg-depleting recombinant human anti-CTLA-4 antibody generated by BioInvent’s proprietary n-CoDeR®/F.I.R.S.T™ platforms, and the human GM-CSF cytokine. By selectively targeting the tumor microenvironment, BT-001 is expected to elicit a much stronger and more effective antitumoral response. Therefore, by reducing systemic exposure, the safety and tolerability profile of the anti-CTLA-4 antibody may be greatly improved.
BT-001 is being co-developed as part of a 50/50 collaboration on oncolytic viruses between Transgene and BioInvent. To know more on BT-001, watch our video .
About Transgene
Transgene (Euronext: TNG) is a biotechnology company focused on designing and developing targeted immunotherapies for the treatment of cancer. Transgene’s programs utilize viral vector technology with the goal of indirectly or directly killing cancer cells.
The Company’s clinical-stage programs consist of a portfolio of therapeutic vaccines and oncolytic viruses:
TG4050, the first individualized therapeutic vaccine based on the myvac® platform, TG4001 for the treatment of HPV-positive cancers, as well as BT-001 and TG6050, two oncolytic viruses based on the Invir.IO® viral backbone.
With Transgene’s myvac® platform, therapeutic vaccination enters the field of precision medicine with a novel immunotherapy that is fully tailored to each individual. The myvac® approach allows the generation of a virus-based immunotherapy that encodes patient-specific mutations identified and selected by Artificial Intelligence capabilities provided by its partner NEC.
With its proprietary platform Invir.IO®, Transgene is building on its viral vector engineering expertise to design a new generation of multifunctional oncolytic viruses.
