BT-001 monotherapy showed stable disease and injected lesions shrinkage in advanced solid tumor patients.
Promising efficacy data in combination with KEYTRUDA® (pembrolizumab) with partial responses in relapsed and refractory advanced melanoma and leiomyosarcoma patients.
Favorable safety profile with minimal adverse events and no dose-limiting toxicities.
Lund, Sweden and Strasbourg, France, September 9, 2024, 07:00 am CEST- 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, and Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, announce initial promising clinical results from the Phase 1 part of the ongoing Phase 1/2a trial of BT-001 as a single agent and in combination with MSD's (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy KEYTRUDA® (pembrolizumab) , to be presented at the European Society of Medical Oncology (ESMO) Annual Meeting to be held in Barcelona, Spain, from September 13 to 17, 2024.
Key findings of the abstract include:
- In the monotherapy part, in terms of overall response, stable disease was observed in 4/18 advanced solid tumor patients receiving BT-001 as single agent, while tumor shrinkage was observed in 2/20 injected lesions .
- In the combination part, two patients with partial responses were observed in a cohort of six heavily pretreated patients with advanced solid tumor receiving BT-001 in combination with pembrolizumab (one patient with a PD(L)-1 resistant melanoma and one patient with a leiomyosarcoma after five lines of therapy). Patient response profiles and updated results to be presented at ESMO.
- BT-001 was well-tolerated with no dose-limiting toxicities (DLTs) observed. Two grade three adverse events related to BT-001 were reported (one skin ulcer and one lymphocyte count decrease). No DLTs were observed with repeated intratumoral injections of BT-001 alone (in 18 patients) or in combination with pembrolizumab (in 6 patients).
- Oncolytic virus BT-001 was shown to replicate and express its anti-CTLA-4 mAb payload in tumor tissue with rare and sporadic shedding , as shown by preliminary translational data.
Alessandro Riva, Chairman and CEO of Transgene , commented: " We are delighted to present these promising initial clinical results from part 1 of the ongoing Phase 1/2a trial of BT-001. We are also excited about the potential of BT-001 as a standout asset within Transgene's oncolytic virus pipeline, further demonstrating the ability of our Invir.IO® platform to generate targeted tumor specific immunotherapies. BT-001 shows preliminary efficacy without dose limiting toxicities both as monotherapy and in combination with pembrolizumab and by modulating the tumor microenvironment. We look forward to reporting further results as this study progresses."
Stéphane Champiat, Medical Oncologist at Gustave Roussy, Head of the Inpatient Unit, Drug Development Department (DITEP) and a clinical investigatior for the study , added: " Many cancer patients fail to respond to existing treatments, highlighting the significant need for new approaches. BT-001 is a very promising potential new immunotherapy shown to elicit a strong immune response that is further enhanced by the local expression of the immune checkpoint inhibitor and the cytokine. The initial clinical data from this study provide important proof of principle and demonstrate the relevance of this oncolytic virus approach. These promising data generated alone or in combination with pembrolizumab offer the chance to deliver better treatment outcomes with an improved safety profile for patients across multiple different cancer indications."
Martin Welschof, CEO of BioInvent stated: "These are exciting data that further support BioInvent's belief that BT-001 has the potential to provide an important new treatment option for patients. BT-001 is one of six programs with five BioInvent generated antibodies, illustrating the power of our scientific understanding and approach to improve treatments for patients with a number of different cancer types."

The abstract #1024P titled " Initialclinical results of BT-001, an oncolytic virus expressing an anti-CTLA4 mAb, administered as single agent and in combination with pembrolizumab in patients with advanced solid tumors" isavailable on ESMO 's and Transgene 's websites.
About BT-001
BT-001 is an oncolytic virus, from the Transgene's invir.IO® platform, with enhanced replication selectivity in tumor cells and recombinantly armed to express 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 aims to induce a strong and effective antitumor response. Consequently, by limiting systemic exposure, this approach aims to significantly improve the safety and tolerability profile of the human anti-CTLA-4 antibody. The ongoing Phase 1/2a trial ( NCT04725331 ) is a multi-center, open-label study, and aims at evaluating safety and antitumor activity of intratumoral BT-001 alone and in combination with pembrolizumab in patients with advanced solid tumors.
About BioInvent
