GRTX Galera Therapeutics Inc

Galera Therapeutics, Inc. (Nasdaq: GRTX), a clinical-stage biopharmaceutical company focused on developing and commercializing a pipeline of novel, proprietary therapeutics that have the potential to transform radiotherapy in cancer, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to Galera’s second product candidate, rucosopasem manganese (rucosopasem), for the treatment of pancreatic cancer.

Rucosopasem is a next-generation selective dismutase mimetic in clinical development to augment the anti-cancer efficacy of stereotactic body radiation therapy (SBRT) in patients with pancreatic cancer and lung cancer. The Company is currently conducting the GRECO-2 Phase 2b randomized, double-blind, placebo-controlled 220-patient trial of rucosopasem in combination with SBRT in patients with locally advanced pancreatic cancer (LAPC).

“Orphan drug designation for rucosopasem highlights the urgent need for more treatment options to extend survival in patients with pancreatic cancer, which is the fourth leading cause of cancer death in the U.S.,” said Mel Sorensen, M.D., Galera’s President and CEO. “Following our announcement of encouraging survival results from our pilot proof-of-concept trial in patients with LAPC in 2021, we initiated the GRECO-2 trial, which is currently enrolling. We believe rucosopasem has the potential to improve the efficacy of SBRT for pancreatic cancer, and we anticipate topline data from GRECO-2 by the end of next year.”

About Orphan Drug DesignationThe U.S. Food and Drug Administration (FDA)’s orphan drug product program is designed to support the development of new drug candidates for the treatment of rare diseases (a condition with a prevalence of less than 200,000 in the U.S.). The FDA has authority to grant orphan drug status to a drug product intended to treat, diagnose or prevent a rare disease or condition. Orphan drug designation provides certain benefits, including market exclusivity upon regulatory approval, exemption of FDA application fees, and tax credits for qualified clinical trials.
