  • Model-informed approach supporting dose selection and optimization of clinical development

  • Confirming wide potential dose-range of BI-1808 in the continued clinical evaluation which already has shown promising single agent safety and efficacy

  • Poster to be presented at PAGE 2024 to be held in Rome, Italy, June 26 to 28, 2024

LUND, SE / ACCESSWIRE / June 26, 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, today announced the presentation of a poster highlighting the model-informed early clinical development of the company's anti-TNFR2 program BI-1808 at the Population Approach Group in Europe (PAGE) 2024 meeting, being held in Rome, Italy from June 26 to 28, 2024.

"The data presented in this poster demonstrate our effective leveraging of a model-informed approach to support dose selection and optimization in the development of our immunomodulatory agent BI-1808," said Martin Welschof, Chief Executive Officer of BioInvent. "The model confirms the wide potential dose range of BI-1808 and will be beneficial in the selection of doses as our clinical evaluation of the asset continues in the ongoing Phase 1/2a study, which has already produced promising initial safety and efficacy results."

BI-1808 could represent a new class of immunomodulatory agent with the potential to improve efficacy of cancer therapy. As earlier communicated, initial efficacy and safety data from the ongoing Phase 1/2a study show so far:
- One complete response (CR), one partial response (PR) that is still improving, and nine patients with stable disease (SD) of 26 evaluable patients in the single agent arm of BI-1808
- Promising signs of efficacy and favorable safety profile in the Phase 1 dose escalation part studying BI-1808 in combination with KEYTRUDA? (pembrolizumab).

Poster summary
The objective was to characterize the population pharmacokinetics (PK), receptor occupancy (RO), and concentrations of the target engagement biomarker soluble tumor necrosis factor receptor 2 (sTNFR2) at different BI-1808 doses, to support the dose selection for the dose expansion trial.

Data and methods
Data was available from patients in the ongoing Phase 1/2a dose escalation trial. Model building and application proceeded in a sequential manner:

  • Development of a joint PK-RO model to simultaneously characterize BI-1808 concentrations and TNFR2 receptor occupancy.

  • Extension of the PK-RO model with a sTNFR2 PD model.

  • Typical value simulations for RO as well as PK and sTNFR2 (not shown) considering different doses and dosing frequencies.
