Fianlimab · Now - Nov 16, 2026 Now · Phase 2 · Resectable Non-small Cell Lung Cancer
Recently reported
cemiplimab Phase 3Mixed · 2026-10-25
C-POST
Primary: Disease-free survival (DFS), the primary endpoint of the Phase 3 C-POST trial of adjuvant Libtayo (cemiplimab) versus placebo in high-risk cutaneous squamous cell carcinoma (CSCC) after surgery and radiation — With a median follow-up of 44 months, efficacy results for Libtayo compared to placebo showed sustained benefits for the primary endpoint of disease-free survival (DFS), and a 37% reduction in the risk of death (hazard ratio [HR]: 0.63; 95% confidence interval [CI]: 0.36-1.11), up from 22% at a median follow up of 30 months (HR: 0.78) and 14% at a median follow up of 24 months (HR: 0.86)
· Patients who were MRD negative at baseline had improved DFS with Libtayo (HR: 0.45; 95% CI: 0.22-0.95); patients who were MRD positive at baseline also had improved DFS with Libtayo (HR: 0.24; 95% CI: 0.07-0.86)
· 61 of 69 placebo patients (88%) with recurrence received subsequent Libtayo (crossover)
· The trial enrolled 415 patients who were randomized to receive either Libtayo (n=209) or placebo (n=206) for up to 48 weeks
Safety: Treatment emergent adverse events (TEAEs) of any grade occurred in 94% of patients in the Libtayo arm and 91% of patients in the placebo arm; Grade ≥3 TEAEs occurred in 26% of patients (Libtayo) and 17% of patients (placebo); treatment discontinuations due to TEAEs occurred in 10% (Libtayo) and 3% (placebo); TEAEs leading to death occurred in 2% of patients in each arm
Estimated readout windows: registry primary-completion date + 6-12 weeks. Windows already open are shown from "Now". Drug names link to ClinicalTrials.gov.
