What the filing says
Zenas presented Phase 3 INDIGO open-label extension data for obexelimab in IgG4-related disease at a conference on October 8–10, 2026. Key findings: 93% probability of remaining flare-free at 12 months (investigator/adjudication confirmed); significantly reduced cumulative glucocorticoid toxicity versus placebo (GTI score difference −11.4, p=0.021); vaccine response sub-study showed 86% seroimmunity to influenza and 100% to COVID-19 after treatment-free window with zero flares (n=7). Lead candidate obexelimab continues advancing toward potential regulatory milestone with SLE Phase 2 SunStone topline expected 4Q 2026.
Why this rating
Positive Phase 3 extension data materially strengthens obexelimab's regulatory pathway and differentiation (steroid-sparing, flare protection); material for $259M-cap biotech with limited late-stage pipeline, but not yet regulatory approval or commercial revenue.
