CUPERTINO, Calif., March 26, 2025 /PRNewswire/ -- DURECT Corporation (NASDAQ:DRRX) today announced financial results for the fourth quarter and full year ended December 31, 2024 and provided a business update.

"We recently achieved significant accomplishments that reinforced our plans for continuing development of larsucosterol for AH and strengthened our balance sheet," stated James E. Brown, D.V.M., President and CEO of DURECT.  "We are excited that NEJM Evidence published the results of our Phase 2b AHFIRM trial in January 2025.  Publication in such a highly regarded, peer reviewed journal provides additional validation of the potential value of larsucosterol as a treatment for AH.  We have incorporated these results, together with the additional AHFIRM data presented at The Liver Meeting 2024, into our planned Phase 3 trial design.  Additionally, in the fourth quarter we completed the sale of the ALZET product line and used the proceeds to repay the entirety of our term loan.  By strengthening our balance sheet, this transaction furthers our strategic goal of advancing development of larsucosterol for AH.  Our primary focus continues to be initiating the Phase 3 trial of larsucosterol for severe AH, contingent on securing sufficient funding.  We are engaged in active dialogue to explore all options for funding the continued development of larsucosterol, including potential business development and financing transactions."

Recent business highlights and updates:

• DURECT is planning a registrational Phase 3 trial to evaluate the safety and efficacy of larsucosterol for the treatment of patients with severe AH. The trial will be a randomized, double-blind, placebo-controlled, multi-center study conducted in the U.S. The primary endpoint will be 90-day survival. The trial design incorporates feedback received from the U.S. Food and Drug Administration (FDA) during a Type B meeting that took place in 2024 under Breakthrough Therapy Designation (BTD) as well as learnings from the prior Phase 2b AHFIRM trial in AH. DURECT's goal is to begin the trial in 2025, subject to obtaining sufficient funding, with topline results expected within two years of trial initiation.
• Results from the AHFIRM Phase 2b trial were published in NEJM Evidence in January 2025. In addition to highlighting the key findings from this study, the article also included new trial data, including subgroup analyses that explain regional differences in patient populations and in AH treatment regimens. Variations in time from hospitalization to first dose highlighted the importance of timely treatment in patients with severe AH. The full article can be accessed here. Top line data from AHFIRM were previously announced in November 2023.
• DURECT delivered an oral and two poster presentations at The Liver Meeting 2024, organized by the American Association for the Study of Liver Diseases (AASLD), in November 2024, in San Diego, California. These presentations showcased additional data from the Phase 2b AHFIRM trial. The data further support the design of the Company's planned Phase 3 trial of larsucosterol, including the importance of timely treatment in driving clinical outcomes.
• In November 2024, DURECT sold its ALZET® line of osmotic pumps to Lafayette Instrument Co. (LIC), a portfolio company of Branford Castle Partners II, L.P., a North-American focused private equity firm. DURECT received $17.5 million from LIC. Simultaneous with this transaction, DURECT paid off all remaining obligations under its term loan agreement with Oxford Finance LLC. As a result of the sale, the operating results from our ALZET product line have been excluded from continuing operations and presented as discontinued operations in the accompanying Condensed Statements of Operations and Comprehensive Income (Loss) and Condensed Balance Sheets for all periods presented.

Financial Highlights for the Fourth Quarter and Full Year 2024:

• Total revenues were $0.5 million and net income was $7.8 million for the three months ended December 31, 2024 compared to total revenues of $0.9 million and net loss of $1.4 million for the three months ended December 31, 2023. Total revenues were $2.0 million and net loss was $7.9 million for the full year ended December 31, 2024, compared to total revenues of $2.6 million and net loss of $27.6 million for the full year ended December 31, 2023.
• As of December 31, 2024, cash, cash equivalents and investments were $12.0 million, compared to cash, cash equivalents and investments of $29.8 million at December 31, 2023.

About the AHFIRM Trial

AHFIRM was a Phase 2b randomized, double-blind, placebo-controlled, international, multi-center study conducted in subjects with severe alcohol-associated hepatitis (AH) to evaluate the saFety and effIcacy of laRsucosterol treatMent (AHFIRM). The study was comprised of three arms and enrolled 307 patients, with approximately 100 patients in each arm: (1) Placebo, which consisted of standard of care, with or without methylprednisolone capsules at the investigators' discretion; (2) larsucosterol (30 mg); and (3) larsucosterol (90 mg). Patients in the larsucosterol arms received the same supportive care without steroids. The primary outcome measure was the 90-day incidence of mortality or liver transplantation for patients treated with larsucosterol compared to those treated with placebo, and the key secondary endpoint was 90-day survival. The Company enrolled patients at clinical trial sites across the U.S., EU, U.K., and Australia. In November 2023, the Company announced topline data for the AHFIRM Trial. Reflecting the life-threatening nature of AH and the lack of therapeutic options, the U.S. FDA has granted larsucosterol Fast Track Designation and Breakthrough Therapy Designation for the treatment of AH. For more information, refer to ClinicalTrials.gov Identifier: NCT04563026.

About Alcohol-associated Hepatitis (AH)

AH is an acute form of alcohol-associated liver disease (ALD) associated with long-term heavy alcohol intake, often following a recent period of increased consumption (i.e., a binge). AH is typically characterized by severe inflammation and liver cell damage, potentially leading to life-threatening complications including liver failure, acute kidney injury and multi-organ failure. There are no FDA approved therapies for AH, and a retrospective analysis of 77 studies published between 1971 and 2016, which included data from 8,184 patients, showed the overall mortality from AH was 26% at 28 days, 29% at 90 days and 44% at 180 days. A subsequent global study published in December 2021, which included 85 tertiary centers in 11 countries across 3 continents, prospectively enrolled 2,581 AH patients with a median Model of End-Stage Liver Disease (MELD) score of 23.5, reported mortality at 28 and 90 days of approximately 20% and 31%, respectively. Stopping alcohol consumption is necessary, but frequently not sufficient for recovery in many moderate (defined as MELD scores of 11-20) and severe (defined as MELD scores >20) patients, and therapies that reduce liver inflammation, such as corticosteroids, are limited by contraindications, have not been shown to improve survival at 90 days or one year, and have demonstrated an increased risk of infection. While liver transplantation is becoming more common for ALD patients, including AH patients, the total number of such transplants is relatively small, and limited by organ availability. Average charges for a liver transplant exceed $875,000, and patients require lifelong immunosuppressive therapy to prevent organ rejection.

About Larsucosterol

Larsucosterol is an endogenous sulfated oxysterol and an epigenetic modulator. Epigenetic regulators are compounds that regulate patterns of gene expression without modifying the DNA sequence. DNA hypermethylation, an example of epigenetic dysregulation, results in transcriptomic reprogramming and cellular dysfunction, and has been reported in many acute (e.g., AH) and chronic diseases (e.g., MASH). As an inhibitor of DNA methyltransferases (DNMT1, DNMT3a and 3b), larsucosterol inhibits DNA methylation, which subsequently modulates expression of genes that are involved in cell signaling pathways associated with stress responses, cell death and survival, and lipid biosynthesis. This may ultimately lead to improved cell survival, reduced inflammation, and decreased lipotoxicity. As an epigenetic modulator, the proposed mechanism of action provides further scientific rationale for developing larsucosterol for the treatment of acute organ injury and certain chronic diseases.

About DURECT Corporation

DURECT is a late-stage biopharmaceutical company pioneering the development of epigenetic therapies that target dysregulated DNA methylation to transform the treatment of serious and life-threatening conditions, including acute organ injury. Larsucosterol, DURECT's lead drug candidate, binds to and inhibits the activity of DNA methyltransferases, epigenetic enzymes that are elevated and associated with hypermethylation found in AH patients. Larsucosterol is in clinical development for the potential treatment of AH, for which the FDA has granted a Fast Track and a Breakthrough Therapy designation; MASH has also been explored.
