• Novel Nonpeptide Drug Conjugate Platform to be Debuted, Featuring Preclinical Profile of Lead Candidate CRN09682 Targeting SST2-Expressing Tumors, which is on Track for IND Submission Early 2025
• Data From Phase 2 Trial of Paltusotine in Carcinoid Syndrome to be Highlighted in Crinetics Symposium and Two Presentations

SAN DIEGO, Nov. 14, 2024 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced two abstracts from its transformative, in-house discovery and development programs will be presented at the upcoming North American Neuroendocrine Tumor Society Multidisciplinary NET Medical Symposium (NANETS 2024), taking place November 21-23, 2024, in Chicago.

“We are eager to share our latest pipeline progress at NANETS 2024. Crinetics is committed to the neuroendocrine tumor community, and we are now utilizing our world class drug discovery and development capabilities to support people living with both functional and non-functional NETs,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “We are excited to present preclinical data from our groundbreaking nonpeptide drug conjugate platform for our lead candidate CRN09682, an investigational anti-tumor therapy targeting SST2-expressing tumors, including NETs. We will also present data from the Phase 2 clinical study of our investigational drug candidate paltusotine, highlighting its ability to reduce the frequency and severity of carcinoid syndrome symptoms in patients with functional NETs.”

CRN09682, is a first-in-class, somatostatin receptor 2 (SST2) targeted, nonpeptide drug conjugate (NDC). Built upon the well-validated concept of antibody-drug conjugates, Crinetics’ NDCs use a highly optimized small molecule G protein coupled receptor (GPCR) ligand, instead of an antibody, to deliver a potent anti-cancer agent to tumor cells with high selectivity and efficiency. CRN09682 was designed to provide enhanced tumor penetration, selectively bind to SST2 expressing tumor cells, induce internalization, and intracellularly release a potent anti-tumor agent, while minimizing systemic exposure and associated toxicities. In addition, CRN09682 is manufactured by traditional chemical synthesis methods, avoiding the complex and heterogeneous manufacturing methods required for antibody drug conjugates. Preclinical data to be presented at NANETS 2024 demonstrate the potent and selective anti-tumor activity of CRN09682, potentially providing a novel alternative for the treatment of NETs and other SST2-expressing tumors.

Another abstract will be featured as both an oral and poster presentation, which includes follow-up from an open-label Phase 2 carcinoid syndrome study of investigational candidate paltusotine, a once-daily, oral, nonpeptide, selective SST2 agonist being developed for the treatment of acromegaly and carcinoid syndrome. The NANETS presentation includes findings from all 36 trial participants, with new analyses that show paltusotine reduced the frequency and severity of carcinoid syndrome symptoms and was well tolerated, justifying further clinical development.

Data for paltusotine and CRN09682, along with additional information on NDCs, will also be featured in a Crinetics-sponsored symposium titled “Paltusotine and CRN09682: Novel Nonpeptide Approaches to Treating Carcinoid Syndrome and Neuroendocrine Tumors” at the conference on Thursday, November 21, from 12:15-1:15 p.m. CT. Featured speakers include Scott Struthers and Dr. Aman Chauhan, leader of Neuroendocrine Oncology and Co-Leader Radiopharmaceutical Drug Development at Sylvester Comprehensive Cancer Center, University of Miami Health System.

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

The poster presentations will be made available on the Crinetics website at the time of presentation in accordance with the NANETS embargo policy.

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.

ABOUT PALTUSOTINE

Crinetics’ lead development candidate, paltusotine, is the first investigational once-daily, oral, selective somatostatin receptor type 2 (SST2) nonpeptide agonist that has completed Phase 3 clinical development for acromegaly and is in Phase 2 clinical development for carcinoid syndrome associated with neuroendocrine tumors. It was designed by Crinetics with the goal of providing a once-daily, oral option for reliable and consistent control of acromegaly and carcinoid syndrome. In Phase 3 studies, once-daily, oral paltusotine maintained IGF-1 levels and symptom control in patients with acromegaly who were switched from monthly injectable medications (PATHFNDR-1) and rapidly decreased IGF-1 levels and symptom burden in medically untreated acromegaly patients (PATHFNDR-2). IGF-1 is the primary biomarker endocrinologists use to manage acromegaly patients. Results from the Phase 2 study in carcinoid syndrome provide supporting data and rationale for paltusotine to initiate a Phase 3 trial for another important indication related to the treatment of carcinoid syndrome in patients with neuroendocrine tumors.

ABOUT CRINETICS PHARMACEUTICALS

Crinetics Pharmaceuticals is a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for endocrine diseases and endocrine-related tumors.
