• Two posters to be presented on early clinical projects from BioInvent’s robust pipeline totaling six clinical programs:
  • Progress with the Phase 1 trial studying BI-1910 as single agent in solid tumors
  • Initial clinical data from the BT-001 Phase 1 study evaluating the candidate both as single agent and in combination with KEYTRUDA® (pembrolizumab) in patients with solid tumors
• European Society for Medical Oncology (ESMO 2024) to be held September 13-17, 2024

Lund, Sweden, July 22, 2024 – 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, announced abstracts for BI-1910 and BT-001 have been selected for presentation at ESMO 2024, being held in Barcelona, Spain from September 13th to 17th, 2024.

BI-1910 is a monoclonal antibody, a TNFR2 agonist, currently enrolling patients in the monotherapy part of the ongoing Phase 1/2a study in patients with advanced solid tumors. BT-001, an anti-CTLA-4 oncolytic virus, is in Phase 1b studies in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy KEYTRUDA® (pembrolizumab), in collaboration with BioInvent’s partner, Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer.

Details of the abstracts to be presented:

The press release contains statements about the future, consisting of subjective assumptions and forecasts for future scenarios. Predictions for the future only apply as the date they are made and are, by their very nature, in the same way as research and development work in the biotech segment, associated with risk and uncertainty. With this in mind, the actual outcome may deviate significantly from the scenarios described in this press release.
