MALVERN, Pa., May 11, 2023 (GLOBE NEWSWIRE) -- 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 financial results for the first quarter ended March 31, 2023, and provided recent corporate updates.

"Galera has made tremendous progress since the start of the year, securing Priority Review designation for our avasopasem NDA, raising $30 million in a registered direct offering, and expanding our commercial leadership team," said Mel Sorensen, M.D., Galera’s President and CEO. “In February, the FDA granted priority review and assigned a PDUFA date of August 9, 2023, to the NDA for avasopasem for the reduction of radiotherapy-induced severe oral mucositis in patients with head and neck cancer. In preparation for the potential U.S. commercial launch of avasopasem in 2023, we built out our commercial leadership team, appointing leading life sciences executives with demonstrated success launching and commercializing market-leading oncology therapies. We look forward to bringing avasopasem to market as potentially the first FDA approved drug for radiotherapy-induced SOM in patients with head and neck cancer.”

Recent Corporate Updates

Radiotherapy-Induced Toxicity Programs:

Severe Oral Mucositis (SOM)

• In February 2023, the Company announced that the U.S. Food and Drug Administration (FDA) accepted for filing and granted priority review to the New Drug Application (NDA) for avasopasem manganese (avasopasem) for radiotherapy-induced SOM in patients with head and neck cancer (HNC) undergoing standard-of-care treatment. With Priority Review designation, the Prescription Drug User Fee Act (PDUFA) target date assigned by the FDA for the NDA is August 9, 2023. The FDA indicated in its acceptance of filing letter that it is not planning to hold an advisory committee meeting on the application.
• Dr. Carryn Anderson, M.D., Clinical Associate Professor of Radiation Oncology at the University of Iowa, presented a net treatment benefit analysis from the Phase 3 ROMAN trial at the European Congress on Head and Neck Oncology (ECHNO), which took place March 8-11, 2023, in Lisbon, Portugal. The analysis demonstrated the overall impact of avasopasem in reducing the burden of SOM.
• Elizabeth Cullen, MSN, ARNP, Nurse Practitioner at the University of Iowa Hospitals and Clinics, presented data from the Phase 3 ROMAN trial and additional information describing the general workflow management for the infusion of avasopasem prior to radiation therapy during the Phase 3 ROMAN study at the Oncology Nursing Society (ONS) Congress, which took place April 26-30, 2023, in San Antonio, TX.
• An abstract featuring avasopasem, "One-year reductions in cisplatin-related chronic kidney disease (CKD) in patients with head and neck (HNC) cancer treated with avasopasem manganese: A prespecified analysis from the phase 3 ROMAN trial," has been selected for a poster presentation as part of the Head and Neck Cancer session at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting, taking place June 2-6, 2023, in Chicago, IL.

Esophagitis

• In May 2022, the Company announced topline results from the open-label, single-arm Phase 2a AESOP trial evaluating avasopasem for its potential to reduce the incidence of radiotherapy-induced esophagitis in patients with lung cancer. The results demonstrated that avasopasem was generally well tolerated and substantially reduced the incidence of severe esophagitis in patients with lung cancer receiving chemoradiotherapy compared to expectations based on review of historical data in the literature. Based on these data, Galera intends to pursue a strategy for avasopasem, if approved for the reduction of SOM, to support the use of avasopasem to reduce radiotherapy-induced esophagitis in patients with lung cancer as a medically accepted indication in published drug compendia.

Anti-Cancer Programs:

Locally Advanced Pancreatic Cancer (LAPC)

• Enrollment is ongoing in the randomized, placebo-controlled Phase 2b GRECO-2 trial of rucosopasem in combination with stereotactic body radiation therapy (SBRT) in patients with LAPC. The primary endpoint of the trial is overall survival. The trial is enrolling well. As a result, the Company plans to expand the target enrollment from 160 to 220 patients in order to accrue the necessary events (number of deaths) for data analysis sooner. Completion of enrollment is now anticipated in the first half of 2024, and topline data readout is expected by the end of 2024.

Non-Small Cell Lung Cancer (NSCLC)

• Enrollment is ongoing in the randomized, placebo-controlled Phase 2 stage of the GRECO-1 trial of rucosopasem in combination with SBRT in patients with NSCLC. Completion of enrollment continues to be anticipated in the second half of 2023, and topline data readout is expected in the second half of 2024.

General Corporate Updates

• On February 17, 2023, the Company completed a registered direct offering, which resulted in the issuance and sale of 14,320,000 shares of common stock and warrants to purchase up to 14,320,000 shares of common stock at a combined offering price of $2.095 per share and accompanying warrant, generating gross proceeds of $30 million. The Company received net proceeds of $27.6 million, after deducting placement agent fees and offering expenses.
• On May 1, 2023, the Company expanded its commercial leadership team with the appointment of accomplished pharmaceutical sales, market access, and commercial operations executives, including Patrick Campbell as Vice President of Sales & Account Management, Elizabeth Turner as Vice President of Market Access, and Henning Thorsen as Vice President of Commercial Operations. The new executives joined Lorraine Walker, Pharm.D., the Company’s Vice President of Marketing. Under the direction of the Company’s Chief Commercial Officer, Mark Bachleda, Pharm.D., MBA, the team is responsible for building out commercial operations, strategy development, and execution in preparation for the potential U.S. commercial launch of avasopasem in 2023.

First Quarter 2023 Financial Highlights

• Research and development expenses were $7.3 million in the first quarter of 2023, compared to $8.1 million for the same period in 2022. The decrease was primarily attributable to a decrease in avasopasem development costs, partially offset by an increase in rucosopasem development costs.
• General and administrative expenses were $6.6 million in the first quarter of 2023, compared to $5.0 million for the same period in 2022. The increase was primarily attributable to avasopasem commercial preparations.
• Galera reported a net loss of $(17.7) million, or $(0.50) per share, for the first quarter of 2023, compared to a net loss of $(15.4) million, or $(0.58) per share, for the same period in 2022.
• As of March 31, 2023, Galera had cash, cash equivalents and short-term investments of $47.8 million. Galera expects that its existing cash, cash equivalents and short-term investments will enable Galera to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2023.
