Galera Reports First Quarter 2021 Financial Results and Recent Accomplishments

Phase 3 ROMAN trial in severe oral mucositis expected to complete enrollment in 1H21; topline data expected in 2H21

Recently announced near doubling of median overall survival observed in placebo-controlled pancreatic cancer trial

Phase 2b pancreatic cancer trial, GRECO-2, expected to commence enrollment in 1H21

MALVERN, Pa., May 11, 2021 (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, 2021, and highlighted recent corporate accomplishments.

“Galera is off to a strong start in 2021, as we continue to progress our clinical oncology programs in radiation-induced severe oral mucositis (SOM), locally advanced pancreatic cancer (LAPC) and non-small cell lung cancer (NSCLC) with our dismutase mimetics,” said Mel Sorensen, M.D., President and CEO of Galera. “We recently reported updated data from our placebo-controlled Phase 1/2 pilot trial, in which a near doubling of median overall survival was observed in patients with pancreatic cancer. Building on the positive results from this trial, we anticipate initiating a Phase 2b trial in the first half of 2021 in patients with LAPC, with overall survival as the primary endpoint. Importantly, we look forward to announcing topline data in the pivotal Phase 3 trial in SOM and potential regulatory approval and commercialization of avasopasem, our lead dismutase mimetic product candidate.”

Recent Corporate Highlights

Severe Oral Mucositis (SOM)

• Continued enrollment in the pivotal Phase 3 ROMAN trial of avasopasem for the treatment of SOM in patients with locally advanced head and neck cancer (HNC) undergoing standard-of-care radiotherapy. The Company remains on track to report topline data in the second half of 2021.
  
  
• The Company expects to report topline data from the Phase 2a EUSOM multi-center trial of avasopasem in Europe in patients with HNC undergoing standard-of-care radiotherapy in the second half of 2021.
  

Locally Advanced Pancreatic Cancer (LAPC)

• Reported updated data from the placebo-controlled Phase 1/2 pilot trial of Galera’s dismutase mimetic in patients with LAPC who are also undergoing stereotactic body radiation therapy (SBRT). As of the data analysis, median overall survival (OS) in the treatment arm (20.1 months) was nearly twice as long as observed in the placebo arm (10.9 months); 29% of patients in the treatment arm achieved a partial response compared to 11% of patients in the placebo arm; and positive results were also observed in local tumor control, time to metastases and progression-free survival. The Company expects to report final results from the trial with at least one year of follow-up on all patients in the second half of 2021.
  

Non-Small Cell Lung Cancer (NSCLC)

• Continued enrollment in the Phase 1/2 GRECO-1 trial of GC4711, Galera’s second dismutase mimetic product candidate, in combination with SBRT in patients with NSCLC. The Company remains on track to report initial data in the first half of 2022.
  

Esophagitis

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

First Quarter 2021 Financial Highlights

• Research and development expenses were $12.4 million in the first quarter of 2021, compared to $14.3 million for the same period in 2020. The decrease was primarily attributable to avasopasem development costs, due to decreased expenses related to the ROMAN trial and a decrease in preclinical expenses.
   
• General and administrative expenses were $5.1 million in the first quarter of 2021, compared to $3.6 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 expenses related to pre-commercial activities for avasopasem.
   
• Galera reported a net loss of $(18.7) million, or $(0.75) per share, for the first quarter of 2021, compared to a net loss of $(18.4) million, or $(0.74) per share, for the same period in 2020.
  
  
• As of March 31, 2021, Galera had cash, cash equivalents and short-term investments of $57.5 million. Galera expects that its existing cash, cash equivalents and short-term investments, together with the expected payments from Blackstone in the amount of $57.5 million upon the achievement of certain clinical enrollment milestones in the ROMAN trial and the anti-cancer program in combination with SBRT under the amended royalty agreement, will enable Galera to fund its operating expenses and capital expenditure requirements into the second half of 2022. The Company expects to achieve these clinical enrollment milestones in the first half of 2021.

About Galera Therapeutics

Galera Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing and commercializing a pipeline of novel, proprietary therapeutic candidates that have the potential to transform radiotherapy in cancer. Galera’s lead product candidate is avasopasem manganese (GC4419, also referred to as avasopasem), a selective small molecule dismutase mimetic initially being developed for the reduction of radiation-induced severe oral mucositis (SOM). Avasopasem is being studied in the Phase 3 ROMAN trial to assess its ability to reduce the incidence and severity of SOM induced by radiotherapy in patients with locally advanced head and neck cancer (HNC), its lead indication. It is also being studied in the EUSOM Phase 2a multi-center trial in Europe assessing the safety of avasopasem in patients with HNC undergoing standard-of-care radiotherapy, the AESOP Phase 2a trial to assess its ability to reduce the incidence of esophagitis induced by radiotherapy in patients with lung cancer, and a Phase 2 trial in hospitalized patients who are critically ill with COVID-19. A pilot Phase 1/2 trial of avasopasem in combination with stereotactic body radiation therapy (SBRT) in patients with locally advanced pancreatic cancer (LAPC) has completed enrollment and reported updated results, with follow-up ongoing. The FDA granted Fast Track and Breakthrough Therapy designations to avasopasem for the reduction of SOM induced by radiotherapy, with or without systemic therapy. Galera’s second dismutase mimetic product candidate, GC4711, is being developed specifically to augment the anti-cancer efficacy of SBRT, and is currently being studied in the GRECO-1 Phase 1/2 trial in combination with SBRT in patients with non-small cell lung cancer. Galera also intends to initiate the GRECO-2 Phase 2b trial of GC4711 in combination with SBRT in patients with LAPC. Galera is headquartered in Malvern, PA.
