Crinetics : Phase 3 Study Of Paltusotine In Acromegaly Meets Primary And Secondary Endpoints

(RTTNews) - Crinetics Pharmaceuticals Inc. (CRNX) said that paltusotine, an oral, once-daily investigational compound, achieved positive results by meeting the primary endpoint and all secondary endpoints of the Phase 3 PATHFNDR-1 study (NCT04837040). The study evaluated paltusotine in patients with acromegaly.

PATHFNDR-1 was a randomized, double-blind, placebo-controlled 36-week treatment period followed by an optional open-label extension study evaluating paltusotine in participants with acromegaly switching from standard-of-care injected depot somatostatin analogs. The study enrolled participants with acromegaly who were biochemically controlled on octreotide or lanreotide depot monotherapy. PATHFNDR-1 is one of two ongoing, placebo-controlled Phase 3 studies of once-daily, oral paltusotine.

The company noted that the study met statistical significance on the primary endpoint, based on the proportion of participants taking paltusotine (83%) who maintained an insulin-like growth factor 1 (IGF-1) level greater than equal to 1.0 times the upper limit of normal (xULN) compared to those taking placebo (4%). All secondary endpoints also met statistical significance.
