• Trial investigates BI-1910 as single agent and in combination with pembrolizumab
• Exploratory expansion cohorts planned in hepatocellular carcinoma and non-small cell lung cancer
• BioInvent now has five drug candidates in six clinical trials, reflecting productivity of technology platform

Lund, Sweden – December 5, 2023 – 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 announces it has enrolled the first patient in its Phase 1/2a trial of the monoclonal antibody BI-1910, the company’s second anti-tumor necrosis factor receptor 2 (TNFR2) program to enter clinical development.

The Phase 1/2a clinical trial will be conducted in the US and Europe and is using an innovative, adaptive design for dose escalation. The first phase of the trial will enroll all solid cancer entities initially as single agent, followed by a dose escalation phase with BI-1910 in combination with pembrolizumab. Subsequently, exploratory expansion cohorts are planned in hepatocellular carcinoma (HCC) and non-small cell lung cancer (NSCLC).

“Enrollment of the first patient in our BI-1910 trial is an important milestone for BioInvent, marking our fifth drug candidate to enter clinical development. Our first anti-TNFR2 antibody, BI-1808, is already progressing well in a Phase 1/2a trial and BI-1910 offers a differentiated approach. Our deep understanding of TNFR2 biology means we can move forward with both these promising and different monoclonal antibodies against a new and promising target for cancer treatment,” said Martin Welschof, CEO of BioInvent.

BI-1910 offers a differentiated, agonist approach to cancer treatment compared to BI-1808, BioInvent’s first-in-class anti-TNFR2 antibody which is currently in a Phase 1/2a trial. Both monoclonal antibodies were chosen as potential best-in-class, from a large family of binders generated through BioInvent’s proprietary F.I.R.S.T™ technology platform.

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.
