Galera Reports Fourth Quarter and Full Year 2021 Financial Results and Recent Corporate Updates

• Positive Phase 3 ROMAN trial of avasopasem for severe oral mucositis met primary and secondary endpoint; Company intends to meet with FDA in 2022 about NDA submission
• Data readouts from AESOP in esophagitis and GRECO-1 in lung cancer expected in 1H 2022
• Strong cash position of $71M with expected cash runway into 2H 2023

MALVERN, Pa., March 10, 2022 (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 fourth quarter and year ended December 31, 2021 and provided recent corporate updates.

“In 2021, we were pleased to report positive data from our lead program evaluating avasopasem for the treatment of severe oral mucositis, a radiotherapy-induced toxicity, in patients with head and neck cancer,” said Mel Sorensen, M.D., Galera’s President and CEO. “The Phase 3 ROMAN trial demonstrated a statistically significant reduction in the incidence of SOM, the primary endpoint, and in the number of days patients experienced SOM. This data is in line with the topline results observed in the Phase 2a EUSOM trial and our previously completed randomized Phase 2b trial, reinforcing avasopasem’s potentially transformative clinical benefit for patients undergoing radiotherapy for head and neck cancer. With this robust package of data in hand, we are preparing to meet with the FDA to discuss the potential NDA submission. Concurrently, we remain on track to report data from our Phase 2a AESOP trial evaluating avasopasem in esophagitis in the first half of this year.”

Dr. Sorensen continued: “We also continue to progress our Phase 1/2 GRECO-1 and Phase 2b GRECO-2 clinical trials evaluating our second product candidate, rucosopasem, in increasing the anti-cancer efficacy of higher daily doses of radiotherapy in patients with non-small cell lung cancer and locally advanced pancreatic cancer, respectively. We look forward to reporting initial data from our GRECO-1 trial in the first half of this year.”

Recent Corporate Updates

Radiotherapy-Induced Toxicity Programs:

Severe Oral Mucositis (SOM)

• On December 14, 2021, the Company announced corrected topline efficacy results from the Phase 3 ROMAN trial of avasopasem for the reduction of SOM in patients with locally advanced head and neck cancer (HNC). The Company had previously announced topline results from the ROMAN trial on October 19, 2021. Upon further analysis following the October announcement, an error by the contract research organization was identified in the statistical program. Correction of this error resulted in improved p-values for the primary and secondary endpoints. The corrected results demonstrated efficacy across multiple SOM endpoints with a statistically significant reduction on the primary endpoint of incidence of SOM and the secondary endpoint of number of days of SOM, more than halving the median number of days a patient experienced SOM. Avasopasem appeared to be generally well tolerated compared to placebo. The Company announced that it plans to meet with the U.S. Food and Drug Administration (FDA) in 2022 to discuss a potential New Drug Application (NDA) submission.
• On December 14, 2021, the Company also reported topline data from the Phase 2a EUSOM multicenter trial of avasopasem in Europe in patients with HNC undergoing standard-of-care radiotherapy. Avasopasem appeared to be generally well tolerated and the incidence and number of days of SOM was in line with the avasopasem data reported in the Phase 3 ROMAN trial.

Esophagitis

• The Company expects to report topline data from the Phase 2a AESOP trial of avasopasem evaluating its ability to reduce the incidence of esophagitis induced by radiotherapy in patients with lung cancer in the first half of 2022.

Anti-Cancer Programs:

Locally Advanced Pancreatic Cancer (LAPC)

• Enrollment is ongoing in the Phase 2b, 160-patient randomized, multicenter, placebo-controlled GRECO-2 trial of rucosopasem, Galera’s second dismutase mimetic product candidate, in combination with stereotactic body radiation therapy (SBRT) in patients with LAPC. The primary endpoint of the trial is overall survival.

Non-Small Cell Lung Cancer (NSCLC)

• Enrollment is ongoing in the Phase 1/2 GRECO-1 trial of rucosopasem in combination with SBRT in patients with NSCLC. The Company expects to report initial data from this trial in the first half of 2022.

Fourth Quarter 2021 Financial Highlights

• Research and development expenses were $9.2 million in the fourth quarter of 2021, compared to $14.6 million for the same period in 2020. 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 $5.3 million in the fourth quarter of 2021, compared to $4.3 million for the same period in 2020. The increase was primarily attributable to employee-related costs from increased headcount and share-based compensation expense, and increased insurance expense and professional fees.
• Galera reported a net loss of $(16.8) million, or $(0.64) per share, for the fourth quarter of 2021, compared to a net loss of $(20.1) million, or $(0.80) per share, for the same period in 2020.
• As of December 31, 2021, Galera had cash, cash equivalents and short-term investments of $71.2 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 second half of 2023.

Full Year 2021 Financial Highlights

• Research and development expenses were $52.4 million for the year ended December 31, 2021, compared to $54.8 million for the year ended December 31, 2020. 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 $21.0 million for the year ended December 31, 2021, compared to $15.7 million for the year ended December 31, 2020. The increase was primarily attributable to employee-related costs from increased headcount and share-based compensation expense, increased expenses related to preparation for potential commercialization of avasopasem, and increased insurance expense and professional fees.
• Galera reported a net loss of $(80.5) million, or $(3.12) per share, for the year ended December 31, 2021, compared to a net loss of $(74.2) million, or $(2.98) per share, for the year ended December 31, 2020.
