Crinetics Pharmaceuticals IncPositive Phase 2 results for atumelnant in congenital adrenal hyperplasia and updated long-term data for paltusotine in acromegaly.

Crinetics Pharmaceuticals presented Phase 2 data from its TouCAHn study of investigational atumelnant in adults with classic congenital adrenal hyperplasia at ENDO 2026. Results from Cohort 4 showed that the once-daily oral ACTH receptor antagonist enabled glucocorticoid dose reductions while maintaining androgen control, with a 67% average reduction in morning serum androstenedione levels at week 12 and 7 of 8 patients reaching physiologic glucocorticoid dosing. The therapy was generally well tolerated, with no treatment-related severe or serious adverse events reported. The company also presented updated long-term data from its PALSONIFY program in acromegaly, showing that once-daily oral paltusotine maintained disease control and was well-tolerated after two years of treatment in pooled open-label extension studies.
