Crinetics Pharmaceuticals and Sanwa Kagaku Kenkyusho Enter into Exclusive Licensing Agreement for the Development and Commercialization of Paltusotine in Japan

SAN DIEGO and NAGOYA, Japan, Feb. 28, 2022 (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, and Sanwa Kagaku Kenkyusho Co., Ltd. ("Sanwa"), an established, fully integrated pharmaceutical company headquartered in Nagoya, Japan, today announced that the parties have entered into a strategic partnership to exclusively develop and commercialize paltusotine in Japan. Paltusotine is Crinetics’ investigational, orally available nonpeptide somatostatin receptor type 2 (SST2) agonist being evaluated as a treatment for acromegaly and neuroendocrine tumors (NETs), including NETs complicated by carcinoid syndrome.

Under the terms of this agreement, Crinetics will receive $13.0 million upfront and will be eligible to receive milestone payments related to the achievement of certain development, regulatory and commercial goals. In addition, upon market approval of paltusotine in Japan, Crinetics will be eligible to receive tiered royalties based on net product sales. Sanwa will have an exclusive right to develop and commercialize the product in Japan and will be responsible for leading the development and commercialization of paltusotine for acromegaly and NETs in Japan. Also, Sanwa will assume all costs associated with clinical trials and regulatory applications associated with these processes. Crinetics retains all rights to develop and commercialize paltusotine outside Japan.

There are approximately 10,000 acromegaly patients and 11,000 NETs patients in Japan and, as in the United States, somatostatin analogues are the first-line medical therapy for individuals for whom surgery is either not prescribed or is not curative. Shusaku Isono, President and Chief Executive Officer of Sanwa Kagaku Kenkyusho Co., Ltd. said “Through this license agreement, we will make our best effort with Crinetics to provide a new oral treatment option for acromegaly and NETs patients in Japan.”

“In Sanwa, we met a company that shares our vision of developing, as the first indication for paltusotine, a once-daily oral therapy for acromegaly that will establish a new class of medicine to allow patients to live full lives free of the burden of painful monthly injections,” added Scott Struthers, Ph.D., founder and Chief Executive Officer of Crinetics. “With the promise of additional indications for NETs, we look forward to a long and productive relationship with our colleagues at Sanwa and are pleased to have the external validation that such a high-quality partnership provides.”

Crinetics is currently enrolling patients in its Phase 3 PATHFNDR program, which is evaluating the safety and efficacy of once-daily oral paltusotine in a wide cross section of acromegaly patients in the United States and Europe. In Japan, Sanwa expects to initiate Phase 1 development with paltusotine in 2022.

About Acromegaly
Acromegaly is a serious disease generally caused by a pituitary adenoma, a benign tumor in the pituitary that secretes growth hormone. Excess GH secretion causes excess secretion of IGF-1 from the liver. Together, excess of these hormones leads to the symptoms and physical manifestations 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 that are not candidates for surgery, or when surgery is unsuccessful in achieving treatment goals. Approximately 50% of patients with acromegaly prove to be candidates for pharmacological treatment. Long-acting somatostatin-receptor ligands (SRLs) are the most common initial pharmacologic treatment; however, these drugs require monthly depot injections with large gauge needles that are commonly associated with pain, injection site reactions, and increased burden of therapy on the lives of patients.

About Neuroendocrine Tumors and Carcinoid Syndrome 
Carcinoid syndrome is a group of symptoms that presents in some individuals with neuroendocrine tumors (NETs). NETs are a rare, slow-growing type of cancer that arises most often in the digestive tract. Carcinoid syndrome is most common in patients with NETs that develop in the lung and gastrointestinal tract and metastasize to the liver. In these cases, the liver is unable to filter the hormones secreted by the NETs, causing them to be circulated systemically and inducing the symptoms of carcinoid syndrome which commonly include diarrhea and flushing. 

About Paltusotine
Paltusotine is an investigational, orally available nonpeptide agonist that is designed to be 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.
