Based on continued encouraging safety, tolerability and clinical activity data observed to date, planned enrollment has increased from 12 to 36 patients.

The expansion is intended to further evaluate the safety, tolerability, dose optimization and preliminary efficacy of the paxalisib-based combination regimen with pembrolizumab and chemotherapy. The expanded dataset is expected to provide a more meaningful assessment of objective response rate ("ORR"), progression-free survival ("PFS") and translational biomarkers. Additional clinical trial updates are anticipated throughout 2026 and into 2027.
