Five abstracts from Crinetics Pharmaceuticals’s clinical development programs, including four late-breaking abstracts, will be presented at the Endocrine Society’s annual meeting, ENDO 2024, taking place June 1-4, 2024 in Boston – including initial data from a Phase 2 Trial of atumelnant in congenital adrenal hyperplasia (CAH).
“This year’s Endocrine Society meeting represents a major milestone for Crinetics as we present initial findings from two clinical studies of atumelnant* (CRN04894), our investigational, once-daily oral ACTH receptor antagonist, in development for the treatment of people with classic congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome, in addition to presentations featuring data from the acromegaly Phase 3 trials of our lead development candidate, paltusotine,” says Scott Struthers, PhD, founder and chief executive officer of Crinetics. “As we work toward submission of the new drug application for paltusotine later this year, and as our second clinical asset, atumelnant, advances through development, we are very pleased with the progress toward our vision of building the premier endocrine-focused pharmaceutical company.”
Two poster presentations will include clinical data for atumelnant, a novel, oral once-daily adrenocorticotropic hormone (ACTH) receptor antagonist in development for classic congenital adrenal hyperplasia (CAH) and ACTH-dependent Cushing’s syndrome. One presentation will showcase initial safety and key biomarker efficacy findings in CAH, including rapid and profound reductions in androstenedione (A4) and 17-hydroxyprogesterone levels in participants, from the Phase 2 open label TouCAHn study. A second presentation includes data from a Phase 1b/2a open-label single center study of atumelnant in ACTH-dependent Cushing’s syndrome and will feature the first evidence of rapid and sustained cortisol reductions in participants.
Crinetics will also have a poster presentation with data from the Phase 3 PATHFNDR-2 study evaluating paltusotine in acromegaly patients who were medically untreated. Additionally, data from the Phase 3 PATHFNDR-1 study of previously treated acromegaly patients who switched to paltusotine from an injected somatostatin receptor ligand, including a new analysis of patient-reported symptoms, will be presented as a poster presentation. Data from the PATHFNDR program will be featured in a Science and Innovation Theater led by Kevin C.J. Yuen, of the Barrow Neurological Institute, on Saturday, June 1, 2024, titled “Paltusotine: A Novel, Investigational Oral Small Molecule Somatostatin Receptor Ligand for Acromegaly.” A third presentation from the paltusotine clinical program will be a poster showing long-term safety and efficacy updates from the Phase 2 ACROBAT Advance open-label extension study.
