One of the principal areas of focus is the management of severe oral mucositis—a painful and debilitating inflammation of the oral mucosa that occurs frequently in head and neck cancer (HNC) patients undergoing radiotherapy combined with chemoradiotherapy. Avasopasem manganese, Galera’s lead product candidate for SOM, is designed to reduce the incidence, duration, and severity of this toxicity. The therapeutic action is based on its ability to neutralize superoxide radicals, thereby mitigating the oxidative damage that underlies the development of mucositis. The clinical trials for avasopasem have progressed through various phases, culminating in pivotal Phase 3 studies that have provided robust data supporting its efficacy in reducing SOM symptoms.

2. Augmentation of Radiotherapy in Combination with SBRT:
Beyond the management of radiotherapy-induced toxicities, Galera is also exploring innovative combination therapies designed to augment the anti-cancer effects of radiotherapy. A novel candidate in this strategic avenue is rucosopasem manganese. This agent is being developed to work synergistically with SBRT, particularly in the context of non-small cell lung cancer (NSCLC) and locally advanced pancreatic cancer (LAPC). By leveraging its redox-modulating properties, rucosopasem aims to both protect normal tissue and enhance tumor cell sensitivity to radiation. Early clinical data have indicated that combining rucosopasem with SBRT may result in not only improved disease control (with indications of partial responses and disease stability) but also in the preservation of pulmonary function in NSCLC patients.

3. Prevention of Cisplatin-Induced Chronic Kidney Disease (CKD):
In patient populations undergoing combined chemoradiotherapy, particularly those treated with cisplatin—a chemotherapy agent with known nephrotoxic potential—Galera has identified an opportunity to improve outcomes. Retrospective analyses from Phase 2b trials have provided evidence that avasopasem manganese may have the kidney-protective effect, reducing the incidence or severity of CKD in head and neck cancer patients post-treatment. This research area is significant, as it highlights the potential for Galera’s molecule to address two major toxicities concurrently: severe oral mucositis and cisplatin-induced renal damage.

4. Broadening Therapeutic Utility Through Mechanistic Innovations:
The company’s research is not confined to a single indication but extends to the broader context of radiotherapy-induced toxicities. There is ongoing preclinical exploration into the mechanisms by which oxidative stress contributes to treatment-induced tissue injury, with the intent of identifying additional clinical applications for Galera’s SOD mimetic platform.
