Efforts to further increase commercial readiness ongoing as Phase 3 PATHFNDR trials of paltusotine in acromegaly approach topline data readouts which are expected in 2H 2023 Phase 2 trial of paltusotine in carcinoid syndrome on track for topline data in 2H 2023 Clinical trials of CRN04894 in ACTH-dependent Cushing’s Syndrome and Congenital Adrenal Hyperplasia expected to begin in 1Q 2023 SAN DIEGO, Jan. 09, 2023 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced that Scott Struthers, Ph.D., founder and chief executive officer of Crinetics, will provide a company update at the 41st Annual J.P. Morgan Healthcare Conference, which is taking place in San Francisco, CA from January 9-12, 2023. Dr. Struthers’ presentation will take place on Wednesday, January 11th at 3:00 p.m. Pacific Time. A live webcast of the presentation may be accessed on the Events page of the company’s website. A replay of the webcast will be accessible at the same location. The presentation will feature an overview of Crinetics’ key priorities and anticipated milestones for 2023. These include: The continued advancement of the Phase 3 PATHFNDR-1 and PATHFNDR-2 trials of once-daily oral paltusotine in acromegaly. The trials remain on track for topline data readouts in the third and fourth quarters of 2023, respectively. If successful, Crinetics plans to submit data from the two studies to regulatory authorities in support of applications seeking approval for the use of paltusotine for all acromegaly patients who require pharmacotherapy, including untreated patients and those switching from other therapies. Efforts to further increase commercial readiness so that the company can rapidly provide acromegaly patients with access to once-daily oral paltusotine, if approved. The continued advancement of the Phase 2 trial of paltusotine in carcinoid syndrome, which remains on track for topline data in the second half of 2023. Following proof-of-concept Phase 1 results for CRN04894, an investigational adrenocorticotropic hormone (ACTH) antagonist, initiating clinical trials in ACTH-dependent Cushing’s syndrome and congenital adrenal hyperplasia. Both studies are expected to begin in the first quarter of 2023. Building off proof-of-concept Phase 1 results for CRN04777, an investigational, oral somatostatin receptor type 5 (SST5) agonist being developed as a treatment for congenital hyperinsulinism. The continued preclinical evaluation of investigational, oral small molecule parathyroid hormone receptor antagonists to identify a candidate for advancement into clinical trials. Initial target indications for this program may include primary hyperparathyroidism and hypercalcemia of malignancy, with potential opportunities in chronic kidney disease also being evaluated.Leveraging the company’s leading G-protein-coupled receptor (GPCR) drug discovery platform to generate and develop additional small molecule drug candidates with the potential to address unmet needs in indications such as polycystic kidney disease, Graves’ Disease (including thyroid eye disease) and metabolic diseases (including diabetes and obesity). “Crinetics is entering 2023 with strong momentum and potentially transformative milestones expected over the next year,” said Dr. Struthers. “If successful, upcoming readouts from our Phase 3 PATHFNDR trials will support regulatory filings seeking paltusotine’s approval in acromegaly, while significantly de-risking its development in carcinoid syndrome. As in acromegaly, many patients with carcinoid syndrome are not well served by burdensome SST2 agonist injections and therefore may benefit from oral paltusotine. We are currently evaluating this hypothesis in a Phase 2 trial that we expect to provide proof-of-concept data later this year.” “Looking broadly, we believe successful readouts from our acromegaly and carcinoid syndrome trials could validate our endocrine driven strategy that is also being applied to CRN04894, CRN04777, and each of our other programs,” continued Dr. Struthers. “Paltusotine is only the first of what we hope will be many future products that will come from the remarkable discovery and development engine that we have built. We are now beginning to lay the foundations for a commercial capability serving the same global community of endocrinologists that are helping us evaluate our drug candidates in their clinics. This coming year will be a critical step towards our long-term goal of building the premier fully integrated endocrine company that can sustainably innovate pioneering therapies for our patients around the world.” 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.

Sept. 28, 2022 12:00 UTC Sparrow has also been granted SME status by the European Medicine Agency PORTLAND, Ore.--(BUSINESS WIRE)-- Sparrow Pharmaceuticals, a clinical-stage biopharmaceutical company developing novel, targeted therapies to address unmet needs in both endocrinology and rheumatology, today announced that the first patient has been dosed in the RESCUE trial, a phase 2 clinical trial of SPI-62, a potent and selective HSD-1 inhibitor, for the treatment of ACTH-dependent Cushing’s syndrome. This study is one of three phase 2 trials planned to investigate SPI-62 as a treatment for disorders of glucocorticoid excess. “Dosing our first patient in this phase 2 trial is an important milestone in our clinical development process of SPI-62,” said Frank Czerwiec, MD, PhD, Chief Medical Officer of Sparrow. “Cushing’s is a devastating rare disease with debilitating morbidities such as depression, bone loss, and diabetes, and if left untreated, high levels of mortality. Current treatments have limited efficacy or serious side effects, so there is a pressing need for new treatments that help these patients mitigate the effects of hypercortisolism.” The international, multicenter, randomized, double- and single-blind, placebo-controlled study is evaluating the pharmacologic effect, efficacy, and safety of SPI-62. The primary endpoint is to determine the pharmacologic effects of SPI-62 in patients with adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome. This includes measurement of the body’s activation of cortisol in important target tissues such as the liver, which is expected to be inhibited by SPI-62. The study will also explore SPI-62’s safety and effect on and Cushing’s features that include hyperglycemia, dyslipidemia, adiposity, hepatic steatosis, hypertension, glaucoma, mood, sleep, pain, osteopenia, and muscle strength. Sparrow is actively enrolling up to 26 patients for the trial, which is being conducted at 16 sites in the U.S., Bulgaria, and Romania. Criteria for participation include male and female subjects, ages 18 years or older, with active and consistent cortisol excess and documented diagnosis of ACTH-dependent Cushing’s syndrome. The company has also been granted SME (small- and medium-sized enterprise) status by the European Medicines Agency (EMA), which allows Sparrow greater access to finance and EU support programs. To learn more about the RESCUE trial (NCT05307328), please visit . About Cushing’s Syndrome and SPI-62 Patients develop Cushing’s syndrome due to an excess of glucocorticoids. In Cushing’s disease, this is due to a pituitary tumor that leads to high levels of adrenocorticotropic hormone, which stimulates excess cortisol secretion. ACTH, or its releasing hormone CRH, may also be produced by non-pituitary tumors. By targeting the intracellular activation of cortisol in key organs, SPI-62 can potentially mitigate multiple signs and symptoms of cortisol excess. HSD-1 inhibition would be the first new mechanism of action in decades to treat Cushing’s. In phase 1 studies, SPI-62 demonstrated the ability to reduce intracellular cortisol in the liver and to inhibit HSD-1 in both the brain and adipose tissue, which are three key tissues in which corticosteroid toxicity leads to morbidity. About Sparrow Pharmaceuticals Sparrow Pharmaceuticals was founded to spare patients the ravages of steroids. Leveraging underappreciated scientific insights into steroid biology, the company is working to provide better treatment options for serious disorders of hypercortisolism, and to revolutionize the treatment of autoimmune and inflammatory conditions. SPI-62, is an oral, small molecule, novel therapeutic treatment designed to target the source of active intracellular glucocorticoids in key tissues.
