Preliminary analysis of one-year progression-free survival data from Phase 2 study of novel SST2 agonist paltusotine under investigation for carcinoid syndrome demonstrated potential anti-tumor effects

SAN DIEGO, Oct. 23, 2025 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced three abstracts from its clinical development programs will be presented at the upcoming North American Neuroendocrine Tumor Society Annual Meeting (NANETS 2025), taking place October 23-25, 2025, in Austin, Texas.

“At the 2025 NANETS annual meeting, we are excited to showcase the continued progress of multiple development programs focused on the treatment of neuroendocrine tumors (NETs),” said Dana Pizzuti, M.D., Chief Medical and Development Officer at Crinetics. “For the first time, we will present progression-free survival data from our Phase 2 study of paltusotine for the treatment of carcinoid syndrome associated with NETs. Details of recently-initiated clinical trials for both paltusotine and our nonpeptide drug candidate (NDC) CRN09682 program will also be presented, demonstrating our deep commitment and continued momentum in the NETs space.”

A preliminary analysis of Phase 2 data from the open-label trial of paltusotine in the treatment of patients with carcinoid syndrome due to NETs will be featured in a poster presentation, showing an overall investigator-assessed progression free survival rate of 74% following one year of treatment.

Paltusotine is approved as PALSONIFY™ in the U.S. as a once-daily oral for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option. Paltusotine is currently being investigated for new indications, including for the treatment of carcinoid syndrome; it is not currently approved in the U.S. or any other countries for the treatment of carcinoid syndrome.

Two additional poster presentations will feature study details from the randomized, Phase 3 trial of paltusotine in carcinoid syndrome due to NETs and the first-in-human study of NDC candidate CRN09682 in patients with somatostatin receptor 2-expressing tumors.

Details on the abstracts to be presented at NANETS are shown below:

About Paltusotine  
Paltusotine, a selectively-targeted somatostatin receptor type 2 (SST2) nonpeptide, is in Phase 3 clinical development for carcinoid syndrome associated with neuroendocrine tumors (CAREFNDR). Results from a Phase 2 study in carcinoid syndrome demonstrated rapid and sustained reductions in flushing episodes and bowel movement frequency, which are the most common symptoms of carcinoid syndrome. PALSONIFY™ (paltusotine) is currently approved in the U.S. for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option.

ABOUT CRN09682
CRN09682 is an investigational, potentially first-in-class, non-radioactive, nonpeptide drug conjugate (NDC) linking a somatostatin receptor 2 (SST2) agonist with the cytotoxic drug monomethyl auristatin E (MMAE) via a spacer and a cleavable linker for the treatment of neuroendocrine tumors (NETs) and potentially for use in other solid tumors that express SST2. The SST2 ligand on the NDC molecule binds to SST2 on the tumor cell surface and is internalized in the cell whereby enzymes cleave the MMAE and release it within the cell. MMAE is known to cause microtubule disruption leading to cell arrest and death. The NDC approach is intended to enhance tumor penetration, selectively bind to specific GPCR expressing tumor cells, induce internalization, and intracellularly release a potent anti-tumor agent, while minimizing systemic exposure and associated toxicities. Additionally, NDCs are manufactured by traditional chemical synthesis methods, avoiding the limitations of fermentation, bioconjugation, and heterogeneous manufacturing methods required by most ADCs. NETs are generally incurable when metastatic, regardless of tumor grade. Overall survival rates vary significantly by stage, grade, age at diagnosis, primary site, and time period of diagnosis.
