"We continued to make progress in our clinical programs investigating DUR-928, our lead epigenetic regulator, during the second quarter. We were pleased to report positive topline data from our Phase 1b NASH trial and we look forward to presenting additional data from the trial at a future scientific meeting," stated James E. Brown, D.V.M., President and CEO of DURECT. "We also initiated a Phase 2 trial of DUR-928 in COVID-19 patients with acute liver or kidney injury and are finalizing our preparations to initiate the Phase 2b trial with DUR-928 in alcoholic hepatitis in the upcoming months. The review of our New Drug Application (NDA) for POSIMIR is also ongoing and we continue to respond to the Agency's requests for information."
Update on Selected Programs:
Epigenetic Regulator Program. DUR-928, the lead product candidate in the Company's Epigenetic Regulator Program, is an endogenous, orally bioavailable, first-in-class small molecule, which may have broad applicability in acute organ injuries such as alcoholic hepatitis (AH) and coronavirus disease 2019 (COVID-19) patients with acute liver or kidney injury as well as in chronic liver diseases such as non-alcoholic steatohepatitis (NASH).
Alcoholic Hepatitis (AH)
- We are working with the FDA and our advisors to finalize the design of a multi-center, international, randomized, double-blind, placebo-controlled Phase 2b clinical trial of DUR-928 in severe AH patients. Patients in the trial will be randomized to receive 30 mg of DUR-928, 90 mg of DUR-928 or placebo. The primary endpoint will be survival rate for patients treated with DUR-928 compared to those treated with placebo. Further details of the trial design, including the size of the trial and other trial parameters will be provided at a future date. We expect to initiate this trial in the second half of 2020.
- During 2019, we completed a Phase 2a clinical trial of DUR-928 in patients with AH. All 19 patients treated with DUR-928 survived the 28-day follow-up period, 74% of patients (14/19) were discharged in = 4 days after receiving a single dose of DUR-928, and there were no drug-related serious adverse events. These results show the potential of DUR-928 as a life-saving therapy for AH patients which currently have an overall historical mortality rate of 26% at 28 days, according to an analysis of 77 studies published between 1971 and 2016, which included data from a total of 8,184 patients.
- AH is an acute form of alcoholic liver disease (ALD) associated with long-term heavy intake of alcohol, and often occurs after a recent period of increased alcohol consumption. AH is typically characterized by recent onset jaundice and hepatic failure. According to the most recent data provided by the Agency for Healthcare Research and Quality (AHRQ), a part of the US Department of Health and Human Services (HHS), there were over 117,000 hospitalizations for patients with AH in 2016. From a recent publication analyzing the mortality and costs associated with AH, the cost per patient is estimated at over $50,000 in the first year. ALD is one of the leading causes of liver transplants in the U.S., costing over $800,000 per patient.
Non-Alcoholic Steatohepatitis (NASH)
- In May 2020, we reported positive topline results from a Phase 1b randomized and open-label clinical study conducted in the U.S. to evaluate safety, pharmacokinetics and signals of biological activity (including clinical chemistry and biomarkers as well as liver fat content and liver stiffness by imaging) of DUR-928 in NASH patients with stage 1-3 fibrosis. A total of 65 patients completed the study. DUR-928 was orally administered daily at 50 mg (n=23), 150 mg (n=21), or 600 mg (300 mg BID (n=21)). Patients in this trial were dosed daily for 4 weeks and followed up for an additional 4 weeks.
- As shown in the table below, significant reductions from baseline (pre-treatment) levels were seen in liver enzymes, liver stiffness as measured by imaging and serum lipids. The Company believes that this demonstration of multiple important liver enzymes, plasma lipids and imaging results moving in the same direction, especially given the short treatment course of four weeks, is a promising indication of DUR-928's potential in NASH.

- DUR-928 was well tolerated at all three doses evaluated. There were no serious adverse events reported during the study. Pharmacokinetic (PK) parameters after repeat dosing were comparable to those after a single dose (from a prior study), indicating no accumulation after repeat dosing.
- Results, including biomarker data, are still being analyzed. DURECT plans to present additional results and data analyses at a future scientific meeting.
- Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease in both children and adults. It is estimated that NAFLD affects approximately 30% to 40% of adults and 10% of children in the United States. NASH, a more severe and progressive form of NAFLD, is one of the most common chronic liver diseases worldwide, with an estimated prevalence of 3-5% globally. No drug is currently approved for NAFLD or NASH.
- We have begun to recruit patients for a randomized, double-blind, placebo-controlled, multi-center Phase 2 study to evaluate the safety and efficacy of DUR-928 in hospitalized COVID-19 infected patients with acute liver or kidney injury.
- A total of approximately 80 patients are planned to be enrolled into two study treatment groups in a 3:1 (DUR-928: placebo) ratio. Patients will receive a dose of 150 mg of DUR-928 or placebo by intravenous infusion on day 1 and day 4 in combination with standard of care therapy, which will be determined by the principal investigator (PI) at each clinical trial site. The primary efficacy endpoint is a composite of survival and being free of acute organ failure (free of mechanical ventilation, free of liver failure events and free of renal replacement therapy) at day 28. Patients will be followed for 60 days. Should any drug product be determined by the FDA to be safe and effective for the treatment of COVID-19 while the trial is ongoing, such treatments may be offered, at each PI's discretion, to any remaining and future patients in this trial.
- COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus (SARS-COV-2). The rapid spread of the disease has resulted in a pandemic with millions of confirmed cases and hundreds of thousands of deaths worldwide. While most cases result in mild symptoms, including fever, cough and shortness of breath, some rapidly progress into acute respiratory distress syndrome (ARDS), multi-organ failure, and death. Many of these patients experience a rapid elevation of inflammation-inducing signaling molecules (cytokine storm) that trigger acute injuries in multiple organs including the liver and the kidney. Organ injury may also occur in hospitalized COVID-19 patients as the result of other complications of the viral infection. In a study of 1,059 adult cases of confirmed hospitalized COVID-19, 62% of patients presented with at least one elevated liver enzyme. In another study, 36.6% of 5,449 patients admitted with COVID-19 had or developed acute kidney injury (AKI).
- The reasons for investigating DUR-928 in this patient population include:
- DUR-928 has demonstrated, both in vitro and in vivo, its ability to stabilize mitochondria, modulate inflammatory responses, and promote cell survival and tissue regeneration, which may render it to be effective in preventing or treating acute organ injury.
- Patients with severe COVID-19 can develop multi-organ injury, including acute kidney, liver and/or cardiac injury, in addition to lung injury and ARDS. Therefore, preventing or successfully treating acute organ injury by alleviating acute cell injury, regulating inflammation, promoting cell survival, and stimulating tissue regeneration could potentially save lives of those hospitalized patients with COVID-19.
- Most relevant to COVID-19 patients with acute liver or kidney injury are results from the recently completed Phase 2a study in AH patients (see above). As in AH patients, COVID-19 patients, especially those with acute liver or kidney injury, are at risk of septic shock and eventually multi organ failure and death. All 19 AH patients dosed with DUR-928 survived the 28-day study, while the historical 28-day mortality rate in AH patients is 26% on average.

- Since the Anesthetic and Analgesic Drug Products Advisory Committee (AADPAC) meeting on January 16, 2020, we have continued to interact with the FDA, including answering information requests, as they continue their review of the POSIMIR NDA.
