rophy in an animal model of ALS. Following these compelling results, we initiated a Phase 2 trial (“DAZALS”) of dazucorilant in patients with ALS. Two hundred forty-nine patients were randomized on a double-blind basis 1:1:1 to receive either 150 mg of dazucorilant, 300 mg of dazucorilant or placebo daily for 24 weeks. Upon completion of the trial, patients were eligible to enter an open-label, long-term extension study, in which they receive 300 mg of dazucorilant for up to 132 weeks.

Although DAZALS did not meet its primary endpoint – change from baseline in the ALS Functional Rating Scale-Revised (ALSFRS-R) in patients who received dazucorilant compared to those who received placebo – a statistically significant reduction in early death was observed at week 24 of the study. An exploratory analysis at the one-year mark found that this benefit continued. Patients who were randomized to receive 300 mg of dazucorilant from the start of DAZALS had an 84 percent reduction in risk of death, compared to patients who received only placebo, with a hazard ratio of 0.16 (p-value: 0.0009). A similar survival benefit was observed in an exploratory analysis of patients who received 300 mg of dazucorilant for greater than 24 weeks, either in the treatment period or in the extension study, compared to patients who received either placebo or 150 mg of dazucorilant for 24 weeks and did not receive dazucorilant in the extension study (hazard ratio: 0.36; p-value 0.02). 

Dazucorilant has demonstrated a manageable safety profile, with 92 percent of adverse events being mild to moderate in severity. The frequency of severe and serious adverse events in patients who received dazucorilant was similar to those who received placebo. Mild to moderate, dose-related, transient abdominal pain was the most common adverse effect. The open-label, long-term extension study, which enrolled 118 patients, is continuing. 

We plan to start a pivotal Phase 3 trial of dazucorilant as a treatment for patients with ALS in 2026.

The FDA has granted dazucorilant Fast Track Designation and orphan drug status for the treatment of ALS in the United States.
