In a groundbreaking development for amyotrophic lateral sclerosis (ALS) research, Woolsey Pharmaceuticals announced the completion of patient enrollment in the high-dose group of the Phase 2a clinical trial for its Rho kinase (ROCK) inhibitor, Bravyl (oral fasudil). This significant milestone paves the way for innovative treatment options for those battling the neurodegenerative disease.

The REAL trial (NTC05218668) initially targeted only a 180 mg daily dose of Bravyl. However, promising safety and efficacy results led the company to expand the study, enabling an investigation into the potential benefits of a higher 300 mg dose. Results are anticipated by mid-next year, and the implications of this trial could be monumental.

"We believe that understanding the effects of this increased dosage in ALS patients will provide invaluable insights as we advance towards larger studies," stated Sven Jacobson, CEO of Woolsey Pharmaceuticals, emphasizing the strategic importance of these findings.

Participants in the trial, particularly those with ALS, often demonstrate elevated ROCK enzyme levels in their blood. This enzyme is known to exacerbate inflammation and cell death while hindering the regeneration of nerve cells. As such, ROCK inhibitors like Bravyl show promise in potentially mitigating these harmful processes, thereby offering new hope not only for ALS but also for various other neurodegenerative conditions.

Interestingly, fasudil, the active component of Bravyl, has already garnered approval in Japan for specific stroke treatments. Recent preclinical studies have suggested its potential to slow ALS progression, igniting interest in its therapeutic capability.

Woolsey Pharmaceuticals has recently secured three patents in the U.S. for Bravyl regarding its application in treating sporadic ALS and formulations designed to assist patients with dysphagia—a common symptom among those suffering from ALS who struggle with swallowing.

The REAL study has so far enrolled 31 participants in its initial segment, all receiving the 180 mg daily dosage for six months. The emerging data are promising: levels of neurofilament light chain (NfL), a reliable biomarker for nerve damage, decreased by 15% post-treatment. Notably, participants exhibited significant clinical improvements over untreated ALS patients, including a remarkable 17% slower deterioration in ALS Functional Rating Scale - Revised (ALSFRS-R) scores, 37% improved lung function, and 56% better muscle strength retention.

Encouraged by these impressive results, Woolsey has initiated recruitment of a new patient group for the 300 mg dosage to determine the best therapeutic dose for future trials. After the main six-month trial, participants will have the opportunity to continue Bravyl treatment in an open-label extension phase lasting up to 2.5 years.

Moreover, evidence from another significant trial, known as ROCK-ALS (NCT03792490), bolsters the expectations surrounding fasudil as a treatment for ALS. This Phase 2 trial examined a specialized fasudil formulation administered intravenously over 20 days to early-stage ALS patients, demonstrating promising safety profiles and potential motor neuron preservation.

These findings depict a beacon of hope for ALS patients and their families. As the results from these pivotal trials emerge, experts believe they may significantly alter the landscape of ALS treatment, opening doors to innovative therapies that could drastically change patients' lives.
