The company highlighted that rezpegaldesleukin more than doubled the treatment effect of placebo and plans to advance the drug into Phase 3 development in 2026.Despite the sell-off, Wall Street analysts responded with bullish revisions following the data release.

The primary endpoint was the mean percentage reduction from baseline in the Severity of Alopecia Tool  score at Week 36. Rezpegaldesleukin demonstrated a favorable safety and tolerability profile, with nearly all treatment-emergent adverse events reported as mild-to-moderate and self-resolving. The discontinuation rate due to adverse events was 1.4% in the combined treatment arms, and no patients discontinued due to injection site reactions.
