Crinetics Pharmaceuticals Presenting New Data from Open Label Extension Trial of Paltusotine in Acromegaly at the Society for Endocrinology BES Congress
Crinetics Pharmaceuticals (Nasdaq: CRNX) announced promising new data from the ACROBAT Advance trial of paltusotine in patients with acromegaly, to be presented at the Society for Endocrinology BES congress in Edinburgh. A total of 84% of eligible participants continued from previous Phase 2 studies. After 51 weeks of treatment, median IGF-1 levels were maintained at lower than washout levels, indicating effective management of the disease. The treatment was generally well tolerated, reinforcing paltusotine's potential as a preferred oral alternative to injected therapies.
- 84% of eligible participants continued into the ACROBAT Advance trial.
- Median IGF-1 levels maintained below washout levels after 51 weeks.
- Paltusotine demonstrated good tolerability among participants.

SAN DIEGO, Nov. 08, 2021 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a clinical stage pharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors, announced today that new data from ACROBAT Advance, the ongoing open label extension (OLE) trial of paltusotine in patients with acromegaly, will be featured in a poster presentation at the annual Society for Endocrinology BES congress in Edinburgh, Scotland. Patients who completed either of the Phase 2 ACROBAT Edge or Evolve studies including a 4-week washout period were eligible to enroll in Advance.
ACROBAT Edge and Evolve were two separate Phase 2 studies that enrolled a broad cross section of acromegaly patients, including those who were biochemically controlled (defined by IGF-1 ≤1.0x upper limit of normal [ULN]) on an injected somatostatin receptor ligand (SRL), as well as those who were uncontrolled (defined by IGF-1 >1.0x ULN) on treatment regimens that included an SRL. Through August 31, 2021,
As of August 31, 2021, 23 of the 41 Advance participants had completed 51 weeks of treatment with only four participants discontinuing from the study. Treatment with paltusotine resulted in median serum insulin-like growth factor-1 (IGF-1) levels that were lower than those observed in the washout (untreated) period in the parent studies and were then stably maintained at levels achieved on prior SRL therapy for up to 51 weeks. This was true for patients with controlled or uncontrolled IGF-1 at baseline while treated with injected SRLs. Results also showed that paltusotine was generally well tolerated.
“It is very encouraging that IGF-1 levels, a clinically recognized biomarker of disease severity and registrational endpoint for acromegaly, have been maintained in Advance participants at levels comparable to those achieved with injected SRLs after almost a year on paltusotine,” said Alan Krasner, M.D., chief medical officer of Crinetics. “This is an important observation that we look forward to monitoring as the OLE continues. We deeply appreciate the enthusiasm and engagement of our study subjects and investigative teams around the world that allow us to continue to gather this important long-term safety and efficacy data.”
“These promising long-term data further support our thesis that once daily oral paltusotine has the potential to replace injected peptide depots as the standard-of-care for acromegaly,” added Scott Struthers, Ph.D., founder and chief executive officer of Crinetics. “They also give us added confidence as we advance through our Phase 3 PATHFNDR program, which aims to support the registration of paltusotine for all acromegaly patients who require pharmacotherapy.”
About Acromegaly
Acromegaly is a serious disease generally caused by a pituitary adenoma, a benign tumor in the pituitary that secretes growth hormone (GH). Excess GH secretion causes excess secretion of IGF-1 from the liver. Together, excess of these hormones leads to the symptoms of acromegaly, including abnormal growth of hands and feet, alteration of facial features, arthritis, carpal tunnel syndrome, joint aches, deepening of voice due to enlarged vocal cords, fatigue, sleep apnea, enlargement of heart, liver and other organs, and changes in glucose and lipid metabolism.
Surgical removal of pituitary adenomas, if possible, is the preferred initial treatment for most acromegaly patients. Pharmacological treatments are used for patients who are not candidates for surgery, or when surgery is unsuccessful in achieving treatment goals. Approximately
About Paltusotine
Paltusotine is an investigational, orally available nonpeptide agonist that is highly selective for the somatostatin receptor type 2 (SST2). It was designed by the Crinetics discovery team to provide a once-daily option for patients with acromegaly and neuroendocrine tumors. A previously completed Phase 1 trial of paltusotine showed clinical proof of concept by providing evidence of potent suppression of the growth hormone axis in healthy volunteers. In Phase 2 trials, paltusotine maintained IGF-1 levels in acromegaly patients who switched from injectable depot medications to once-daily oral paltusotine. IGF-1 is the primary biomarker endocrinologists use to manage their acromegaly patients.
About Crinetics Pharmaceuticals
Crinetics Pharmaceuticals is a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors. The company’s lead product candidate, paltusotine (formerly CRN00808), is an investigational, oral, selective nonpeptide somatostatin receptor type 2 biased agonist for the treatment of acromegaly, an orphan disease affecting more than 26,000 people in the United States. A Phase 3 clinical program in acromegaly with paltusotine is underway. Crinetics also plans to advance paltusotine into a Phase 2 trial for the treatment of carcinoid syndrome associated with neuroendocrine tumors. The company is also developing CRN04777, an investigational, oral, nonpeptide somatostatin receptor type 5 (SST5) agonist for congenital hyperinsulinism, as well as CRN04894, an investigational, oral, nonpeptide ACTH antagonist for the treatment of Cushing’s disease, congenital adrenal hyperplasia and other diseases of excess ACTH. All of the company’s drug candidates are new chemical entities resulting from in-house drug discovery efforts and are wholly owned by the company.
