EU CTIS ID: 2024-511023-34-00
What this study is testing
DOSE OPTIMIZATION LEAD-IN: -To evaluate the safety and tolerability of 90 mg efti combined with paclitaxel, compared to 30 mg. -To define the optimal biological dose (OBD) of efti in combination with weekly paclitaxel for Phase 3 part of the trial. PHASE 3: -To demonstrate that OS is superior in patients treated with efti combined with weekly paclitaxel compared to weekly paclitaxel plus placebo.
