Announcement
DURECT Corporation announced the publication of a peer-reviewed article on the AHFIRM trial data in NEJM Evidence.
AI Summary
DURECT Corporation announced the publication of a peer-reviewed article in NEJM Evidence detailing the AHFIRM trial data. The article, titled “Larsucosterol for the Treatment of Alcohol-Associated Hepatitis,” explains how larsucosterol, an epigenetic modulator, was evaluated in patients with severe alcohol-associated hepatitis in a Phase 2b randomized, double-blind study. The trial involved 307 patients divided among three treatment arms—including two different doses of larsucosterol—against a placebo group receiving standard care. Detailed subgroup analyses and liver biomarker data provided important insights, helping researchers understand larsucosterol’s potential benefits and safety profile. These findings have been instrumental in guiding the design of a forthcoming Phase 3 trial, which will focus on U.S. patients and use 90-day mortality as its primary endpoint. The publication of these results in a respected journal underscores the significance of larsucosterol as a promising treatment option for a challenging condition.

Announcement
DURECT Corporation today provided details on the design of its upcoming registrational Phase 3 trial which will evaluate larsucosterol for the treatment of patients with severe alcohol-associated hepatitis (AH).
AI Summary
DURECT Corporation has shared details for its upcoming Phase 3 trial to evaluate larsucosterol for patients suffering from severe alcohol-associated hepatitis (AH). The single, multi-center, randomized, double-blind, placebo-controlled study in the United States is planned to enroll about 200 patients. The trial’s primary endpoint is 90-day survival, with topline results expected within two years of starting the study.
The trial design builds on promising Phase 2b AHFIRM data, where both 30 mg and 90 mg doses of larsucosterol showed nearly a 60% reduction in 90-day mortality among U.S. patients compared to placebo. During a recent Type B meeting with the FDA under Breakthrough Therapy designation, key protocol elements were agreed upon, and the FDA confirmed that a single Phase 3 trial will suffice to support a New Drug Application.

Announcement
DURECT Corporation announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation (BTD) to larsucosterol for the treatment of patients with severe alcohol-associated hepatitis (AH).
AI Summary
DURECT Corporation announced that the FDA has granted Breakthrough Therapy designation to larsucosterol for treating patients with severe alcohol-associated hepatitis (AH). This designation underscores the potential of larsucosterol as a promising treatment option for a life-threatening condition with high mortality rates and no approved therapies. Encouraging clinical evidence from the Phase 2b AHFIRM trial has supported this decision, highlighting the drug’s possible benefits in enhancing survival and reducing liver inflammation in AH patients.
DURECT is now finalizing the design of a registrational Phase 3 clinical trial to further evaluate the safety and efficacy of larsucosterol. The company is optimistic that this expedited pathway will allow for more focused development and review, potentially bringing a much-needed treatment to patients suffering from severe AH. Future clinical updates will be shared as additional data becomes available.
