Usnoflast for ALS

(UNITE-ALS Trial)

This trial tests a new treatment called Usnoflast for individuals with Amyotrophic Lateral Sclerosis (ALS), a condition affecting nerve cells in the brain and spinal cord, leading to muscle weakness. Researchers aim to determine if Usnoflast can improve symptoms or slow ALS progression. The study includes groups receiving either 50 mg or 75 mg doses of Usnoflast or a placebo (inactive pill) to compare effects. Individuals who have experienced ALS symptoms, such as limb weakness or difficulty speaking or swallowing, for less than two years might be suitable for this trial. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

You may need to stop certain medications before joining the trial. If you're taking riluzole, sodium phenylbutyrate, taurursodiol, or edaravone, you can continue them if your dose is stable. However, you must stop medications that affect drug metabolism or absorption, like St. John's Wort, and certain other drugs at least 7 days or 5 half-lives before starting the trial.

Research has shown that Usnoflast is generally safe for people with ALS. Studies found that taking either 50 mg or 75 mg doses of Usnoflast resulted in only a few side effects. These findings support further research on Usnoflast for ALS.¹²³⁴⁵

Usnoflast is unique because it offers a new approach to treating ALS by using a specific active ingredient not found in current options. Most ALS treatments, like riluzole and edaravone, aim to slow disease progression or reduce oxidative stress. But Usnoflast works differently, potentially targeting other mechanisms involved in ALS. This fresh approach could provide new hope for slowing down the disease even further. Researchers are excited about its potential to address aspects of ALS that standard treatments might not fully cover.

Research has shown that Usnoflast may help slow the progression of ALS, a disease affecting nerve cells in the brain and spinal cord. In earlier studies, patients tolerated Usnoflast well, and it appeared to slow the loss of abilities. It also improved breathing, which is crucial for people with ALS. Although not all results reached statistical significance, patients taking the 75 mg dose, one of the treatment arms in this trial, achieved better scores on a test measuring ALS progression. These encouraging findings suggest Usnoflast could be a helpful treatment for ALS.¹²³⁴⁶
