Mezagitamab vs SG301
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.

NCT03439280 · Phase 1/2 · completed
This was a nonrandomized, open-label, single-arm dose-escalation study of 50 participants, with no placebo or active comparator. Its primary outcomes focused on safety, including treatment-emergent adverse events and dose-limiting toxicities, rather than a controlled efficacy comparison; 50 of 50 participants reported at least one treatment-emergent adverse event, and 1 of 41 dose-limiting-toxicity-evaluable participants had a dose-limiting toxicity.
