MALVERN, Pa., Aug. 10, 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 second quarter ended June 30, 2021, and highlighted recent corporate accomplishments.

“We had a highly productive quarter in the clinic, including completion of enrollment in our 455-patient pivotal Phase 3 ROMAN trial of our lead product candidate, avasopasem, for SOM in patients with head and neck cancer, promising tumor outcome and survival data in an interim analysis of our 42-patient pancreatic cancer trial, and initiation of our 160-patient double-blinded placebo-controlled GRECO-2 pancreatic cancer trial,” said Mel Sorensen, M.D., President and CEO. “We look forward to reporting clinical trial results from our key programs later this year. In parallel, Galera continues to strengthen our cash position and build our commercial capabilities as we work toward potential FDA approval of avasopasem in radiotherapy-induced SOM.”

Recent Corporate Highlights

Severe Oral Mucositis (SOM)

• Completed enrollment in the pivotal Phase 3 ROMAN trial of avasopasem for SOM in patients with locally advanced head and neck cancer (HNC) undergoing standard-of-care radiotherapy, which triggered a $37.5 million milestone payment from funds managed by Blackstone Life Sciences (Blackstone) received in July 2021. The Company expects to report topline data in the fourth quarter 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 fourth quarter of 2021.
  

Locally Advanced Pancreatic Cancer (LAPC)

• Reported updated data from the placebo-controlled 42-patient trial of Galera’s dismutase mimetic in patients with LAPC who are undergoing stereotactic body radiation therapy (SBRT). The updated results include a minimum follow-up of six months on all 42 patients. As of the interim data analysis, median overall survival in the treatment arm (20.1 months) was nearly twice as long as observed in the placebo arm (10.9 months); 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 third quarter of 2021.
  
  
• Initiated the 160-patient randomized, multicenter, placebo-controlled GRECO-2 trial of GC4711, Galera’s second dismutase mimetic product candidate, in combination with SBRT in patients with LAPC in May 2021, which triggered a $20 million milestone payment from Blackstone received in June 2021.
  

Non-Small Cell Lung Cancer (NSCLC)

• Enrollment is ongoing in the Phase 1/2 GRECO-1 trial of GC4711 in combination with SBRT in patients with NSCLC. The Company expects to report initial data from this trial in the first half of 2022.
  

Esophagitis

• Enrollment is ongoing 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.
  

Second Quarter 2021 Financial Highlights

• Research and development expenses were $16.0 million in the second quarter of 2021, compared to $13.8 million for the same period in 2020. The increase was primarily attributable to avasopasem development costs due to increased clinical expenses, primarily related to the ROMAN trial, and an increase in manufacturing and regulatory activities.
  
  
• General and administrative expenses were $5.1 million in the second quarter of 2021, compared to $3.9 million for the same period in 2020. The increase was primarily attributable to employee-related costs from increased headcount and share-based compensation expense, increased expenses related to pre-commercial activities for avasopasem, and increased insurance expense and professional fees.
  
  
• Galera reported a net loss of $(22.4) million, or $(0.88) per share, for the second quarter of 2021, compared to a net loss of $(18.7) million, or $(0.75) per share, for the same period in 2020.
  
  
• As of June 30, 2021, Galera had cash, cash equivalents and short-term investments of $66.5 million. Galera expects that its existing cash, cash equivalents and short-term investments, together with the payment from Blackstone in the amount of $37.5 million received in July 2021, will enable Galera to fund its operating expenses and capital expenditure requirements for at least the next twelve months.

Avasopasem is also in development for radiotherapy-induced esophagitis in patients with lung cancer. Avasopasem has been granted FDA Fast Track and Breakthrough Therapy designations for the reduction of SOM induced by radiotherapy, with or without systemic therapy. Galera’s second dismutase mimetic product candidate, GC4711, is in clinical-stage development to augment the anti-cancer efficacy of stereotactic body radiation therapy in patients with non-small cell lung cancer and locally advanced pancreatic cancer.
