MINNEAPOLIS, July 14, 2025 (GLOBE NEWSWIRE) -- Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced the issuance of U.S. Patent No. 12,350,276 covering the clinical dosing regimen for its lead drug candidate, gedatolisib, in ER+/HER2- breast cancer patients. The patent extends Celcuity's patent exclusivity in the U.S. into 2042.

"This dosing regimen patent reflects our commitment to enhancing our intellectual property portfolio," said Brian Sullivan, CEO and Co-Founder of Celcuity. "With patent exclusivity for gedatolisib now extended into 2042, we expect to have a long runway to optimize development of gedatolisib."

The worldwide gedatolisib-related patent portfolio now comprises 13 granted gedatolisib-related patents in the U.S. and 290 patents granted in foreign jurisdictions.

Celcuity expects to announce topline data for the PIK3CA wild-type cohort of the VIKTORIA-1 clinical trial in the third quarter of 2025 and to report topline data for the PIK3CA mutant cohort in the fourth quarter of 2025.

About Celcuity

Celcuity is a clinical-stage biotechnology company pursuing development of targeted therapies for treatment of multiple solid tumor indications. The company's lead therapeutic candidate is gedatolisib, a potent, pan-PI3K and mTORC1/2 inhibitor that comprehensively blockades the PI3K/AKT/mTOR ("PAM") pathway. Its mechanism of action and pharmacokinetic properties are differentiated from other currently approved and investigational therapies that target PI3Ka, AKT, or mTORC1 alone or together. A Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- advanced breast cancer is currently enrolling patients. A Phase 1/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic castration resistant prostate cancer, is ongoing. A Phase 3 clinical trial, VIKTORIA-2, evaluating gedatolisib plus a CDK4/6 inhibitor and fulvestrant as first-line treatment for patients with HR+/HER2- advanced breast cancer is currently recruiting patients.
