Galera Therapeutics Announces Presentation of Data from Phase 2b Clinical Trial of GC4419 at 2018 American Society of Clinical Oncology (ASCO) Annual Meeting

World News: . []

MALVERN, Penn., May 16, 2018 (GLOBE NEWSWIRE) -- Galera Therapeutics, Inc., a clinical-stage biotechnology company developing drugs targeting oxygen metabolic pathways with the potential to transform cancer radiotherapy, today announced that data from its Phase 2b clinical trial of GC4419 for severe oral mucositis in patients with head and neck cancer will be presented during an oral abstract session at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting, to be held June 1-5, 2018 in Chicago. GC4419 is a highly selective and potent small molecule dismutase mimetic that rapidly converts superoxide to hydrogen peroxide and oxygen.

Presentation details are as follows:

The abstract has also been selected for inclusion in the 2018 Best of ASCO program, which aims to increase global access to cutting-edge science by condensing highlights from ASCO’s Annual Meeting into a two-day program to be held this summer.

GC4419 is a highly selective and potent small molecule dismutase mimetic that closely mimics the activity of human superoxide dismutase enzymes. GC4419 works to reduce elevated levels of superoxide caused by radiation therapy by rapidly converting superoxide to hydrogen peroxide and oxygen. Left untreated, elevated superoxide can damage noncancerous tissues and lead to debilitating side effects, including oral mucositis (OM), which can limit the anti-tumor efficacy of radiation therapy. Conversion of elevated superoxide to hydrogen peroxide, which is selectively more toxic to cancer cells, can also enhance the effect of radiation on tumors, particularly with stereotactic body radiation therapy (SBRT), which produces high levels of superoxide. 

GC4419 has been studied in patients with head and neck cancer, GC4419’s lead indication, for its ability to reduce the duration, incidence and severity of radiation-induced severe oral mucositis (SOM). Results from Galera’s 223-patient, double blind, randomized, placebo-controlled Phase 2b clinical trial demonstrated GC4419’s ability to dramatically reduce the duration of SOM from 19 days to 1.5 days (92 percent), the incidence of SOM through completion of radiation by 34 percent and the severity of patients’ OM by 47 percent, while demonstrating acceptable safety when added to a standard radiotherapy regimen. In addition, in multiple preclinical studies, GC4419 demonstrated an increased tumor response to radiation therapy while preventing toxicity in normal tissue.

The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation to GC4419 for the reduction of the duration, incidence and severity of SOM induced by radiation therapy with or without systemic therapy. The FDA also granted Fast Track designation to GC4419 for the reduction of the severity and incidence of radiation and chemotherapy-induced OM.

Galera Therapeutics, Inc. is a privately held, clinical-stage biotechnology company focused on discovering and developing novel therapeutics targeting oxygen metabolic pathways with the potential to transform how radiation therapy is used in patients with cancer. Galera’s lead product candidate is GC4419, a highly selective and potent small molecule superoxide dismutase enzyme mimetic that rapidly converts superoxide to hydrogen peroxide and oxygen. GC4419 achieved positive results in a Phase 2b clinical trial, which demonstrated its ability to reduce the duration, incidence and severity of radiation-induced severe oral mucositis in patients with head and neck cancer, its lead indication. The U.S. Food and Drug Administration granted Fast Track and Breakthrough Therapy designations to GC4419. Galera is headquartered in Malvern, PA. For more information, visit .
