New acromegaly drug on the horizon

A new drug for treatment and long-term maintenance therapy for acromegaly is now on the horizon. Crinetics Pharmaceuticals recently submitted its first new drug application (NDA) to the U.S. Food and Drug Administration for paltusotine, which is a once-daily oral selectively-targeted somatostatin receptor type 2 nonpeptide agonist.

Crinetics says researchers used data from from 18 clinical trials in the application, including two Phase 3 trials that evaluated paltusotine for acromegaly in medically untreated and treated patients.   Patients tolerated the treatment well, the medication achieved biochemical control by maintaining IGF-1 levels and improved patients’ symptoms compared to placebo.   The company says it expects to hear back from the FDA by December.

Paltusotine, is the first drug of its type to complete Phase 3 clinical development for acromegaly and is now in Phase 2 clinical development for carcinoid syndrome associated with neuroendocrine tumors.  Read the company’s press release here.
