Penpulimab
Marketed by Akeso
NCT03866993 · Phase 3 · completed
This randomized, placebo-controlled trial kept participants, care providers, investigators and outcome assessors blind to treatment assignment, with disease progression assessed by an independent radiology committee. Its primary endpoint, progression-free survival, was clearly met, roughly doubling median progression-free survival versus placebo plus chemotherapy.
Sasanlimab
Developed by Pfizer
NCT04181788 · Phase 1/2 · completed
Phase 1/2 open-label study in advanced malignancies (155 participants). The primary endpoints are dose-limiting toxicities and pharmacokinetic exposure, reported descriptively; no efficacy hypothesis was tested as a primary comparison.
Next expected readout: October 2026 · NCT06447662 (registry estimate)
