DURECT Corporation Publishes Promising Larsucosterol Findings for Alcohol-Associated Hepatitis

DURECT Corporation Publishes Findings on Larsucosterol

DURECT Corporation (Nasdaq: DRRX) has recently announced the publication of crucial Phase 2b trial results regarding its investigational drug, Larsucosterol, in the reputable NEJM Evidence journal. This update follows the AHFIRM trial that focused on patients suffering from severe alcohol-associated hepatitis (AH).

The AHFIRM trial was an extensive Phase 2b randomized, double-blind, placebo-controlled, international study that explored the safety and effectiveness of Larsucosterol as a treatment option. It involved a patient population of 307 individuals divided into three groups: those receiving a placebo, those receiving 30 mg of Larsucosterol, and those receiving a higher dose of 90 mg. Notably, 76% of participants were enrolled from clinical sites within the United States.

Dr. Mitchell Shiffman, Director of the Liver Institute of Virginia and the principal investigator for this study, expressed optimism about the results, emphasizing the urgent need for effective therapies for the AH patient community, where historically, many medications have failed to receive regulatory approval or show consistent efficacy.

The trial’s key findings included a trend toward reduced mortality at 90 days post-treatment. Although not statistically significant, there was a clear decrease in mortality rates of 41% for the 30 mg dose and 35% for the 90 mg dose when compared to the placebo group. Interestingly, results were notably better among U.S. patients, echoing a mortality reduction of 57% in the lower dose and 58% in the higher dose.

In addition to mortality findings, the trial provided insights regarding patient management, particularly stressing the importance of timely treatment initiation. Common complications associated with AH highlight the dire need for timely interventions to improve patient outcomes.

Beyond mortality rates, the safety profile of Larsucosterol appeared favorable, with adverse events similar to control groups. This is a crucial aspect, given that effective treatment options for AH are limited and current therapies pose risks and side effects.

For DURECT Corporation, these findings form a critical foundation for their impending Phase 3 trial, which is designed with a focus on a robust protocol based on comprehensive analyses from the AHFIRM study. The upcoming trial will concentrate on U.S. patients and aims to finalize mortality at 90 days as the primary endpoint. Furthermore, the FDA's recognition of Larsucosterol with Fast Track and Breakthrough Therapy designations significantly bolsters its development trajectory.

Additionally, DURECT’s President and CEO, James E. Brown, D.V.M., highlighted the company's anticipation surrounding the Phase 3 trial. With funding considerations underway, the initiation of this trial is anticipated in 2025. The trial's success could potentially streamline the approval process for Larsucosterol, marking a significant step in addressing the treatment challenges associated with alcohol-related liver diseases.

Alcohol-associated hepatitis, stemming from chronic heavy alcohol consumption, presents severe complications, including liver damage and potentially fatal systemic issues. Despite its acute nature, no medicines have been FDA approved for treating AH, making the need for effective therapeutic solutions dire. Current estimates indicate that survival rates drop significantly after short intervals, underlining the urgency for actionable treatments.

Larsucosterol, an epigenetic modulator with mechanisms targeting malfunctions in DNA methylation, holds promise for improving liver health and patient outcomes. The study results emphasize that the urgency to act on alcohol-associated hepatitis cannot be overstated, as the patient population grapples with limited options and substantial mortality rates.

In conclusion, as DURECT Corporation leads the way in pioneering epigenetic therapies, the data from the AHFIRM trial offers a beacon of hope for patients battling alcohol-associated hepatitis. The scientific community now eagerly awaits the results of the forthcoming Phase 3 trial, which may provide the breakthrough that this ailment urgently needs.
