Phase 2 | 92 | rezpegaldesleukin low dose | tbwdlgdeoe(asasacsqce) = Both treatment arms “more than doubled the SALT score reduction than that observed with placebo, with the majority of patients experiencing hair growth at Week 16 or later.” Participants in the higher-dose group had an average 28% improvement in hair coverage, compared with about 11% in the placebo group. When researchers removed data from four patients who did not meet key eligibility requirements, both drug doses showed statistically significant improvements, with hair regrowth of roughly 30%, compared with just under 6% for placebo. plyicixncw (kgorhyzrqq ) View more | Positive | 17 Dec 2025 | ||
