CS1001 Monoclonal Antibody vs Envafolimab
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

CS1001 Monoclonal Antibody
Developed by CStone Pharmaceuticals
NCT03728556 · Phase 3 · completed
In this randomized, quadruple-blind, placebo-controlled Phase 3 trial, 381 patients with stage III lung cancer who had completed chemoradiotherapy were randomized to sugemalimab or placebo. Sugemalimab significantly reduced the risk of progression or death compared with placebo (median progression-free survival 10.5 vs 6.2 months).
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
Envafolimab
Developed by Suzhou Alphamab and partners
NCT05068427 · Phase 2 · completed
The study was an open-label, single-arm trial of 34 patients receiving chidamide plus envafolimab, with no randomized control group for comparison. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Next expected readout: December 2026 · NCT05024214 (registry estimate)
