"We are pleased to be working with the FDA on the design of a double-blind, multi-center, placebo-controlled clinical study to evaluate the safety and efficacy of DUR-928 in COVID-19 patients with acute liver or kidney injury," stated James E. Brown, D.V.M., President and CEO of DURECT. "The first quarter was largely about adjusting to the challenges posed by the COVID-19 pandemic and planning our next clinical study of DUR-928 in alcoholic hepatitis, while continuing to make progress on our other key programs. In addition to initiating discussions with the FDA regarding the potential use of DUR-928 in COVID-19 patients, we were fortunate during Q1 to be able to complete enrollment in our NASH trial and respond to several information requests from the FDA as they continue their review of our New Drug Application (NDA) for POSIMIR."
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 COVID-19 patients with acute liver or kidney injury as well as in chronic liver diseases such as non-alcoholic steatohepatitis (NASH).
We are working with the FDA on the design of a double-blind, placebo-controlled, multi-center, proof-of-concept Phase 2 study to evaluate the safety and efficacy of DUR-928 in approximately 80 COVID-19 patients with acute liver or kidney injury.
- Coronavirus disease 2019 (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 more than 4 million confirmed cases and over 280,000 deaths worldwide, over 79,000 of which have occurred in the United States as of this writing. While most cases result in mild symptoms, including fever, cough and shortness of breath, some progress into severe pneumonia and multi-organ failure, potentially as a result of severe immune overreaction (a cytokine storm), or as a result of ischemic injury, or other complications. Several studies reported that up to half of hospitalized patients with COVID-19 had elevated liver enzyme levels that signal liver injury and more than a third of hospitalized patients had kidney damage.
- The reasons for potentially testing 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 acute respiratory distress syndrome (ARDS). Therefore, one could potentially save lives of those hospitalized patients with COVID-19 if one could prevent or treat acute organ injury by alleviating acute cell injury, regulating inflammation, promoting cell survival, and stimulating tissue regeneration.
- Acute liver or kidney injury is a risk factor for poor outcomes in COVID-19 patients. These patients are being excluded from many ongoing anti-viral COVID-19 trials and are in great need of a new therapy.
- 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 below). All 19 patients dosed with DUR-928 survived the 28-day study, while the historical 28-day mortality rate in AH patients is 26% on average.
- To date, DUR-928 has been dosed in more than 280 subjects, both healthy volunteers and patients, in multiple Phase 1 and 2 studies and has been well tolerated. No serious adverse events have been associated with the drug.
Alcoholic Hepatitis (AH)
- During 2019, we completed a Phase 2a clinical trial of DUR-928 in patients with AH. All 19 patients treated with DUR-928 in the AH trial survived the 28-day follow-up period and there were no drug-related serious adverse events. The study results were presented as a late-breaking oral presentation at The Liver Meeting® 2019 by Dr. Tarek Hassanein, one of the trial's principal investigators. In a separate poster presentation, Dr. Craig McClain presented additional comparative data from the Phase 2a clinical trial of DUR-928 and a control group of severe AH patients treated with corticosteroids in a contemporaneous AH trial conducted at University of Louisville. Additionally, the DUR-928 results were selected for inclusion in the "Best of The Liver Meeting" summary slide deck in the Alcohol-related Liver Disease category. Inclusion in this slide deck is considered a singular honor and indicates the high level with which the AASLD review committee regarded this study.
- 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. An analysis of 77 studies published between 1971 and 2016, which included data from a total of 8,184 patients, showed the overall mortality from AH was 26% at 28 days. 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.
- 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 goal of the trial will be to demonstrate a superior 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 details on the endpoints will be provided at a future date. Due to the COVID-19 pandemic, we are updating our guidance for initiation of this trial and now expect the trial to begin enrolling patients in the second half of 2020.
Non-Alcoholic Steatohepatitis (NASH)
- We have completed enrollment in the ongoing NASH trial. 62 patients have completed dosing and their final visits. Clinical data from the last few patients are being collected, while only a few were unable to complete final visits due to COVID-19 related office closings and travel restrictions. The Company remains on track to announce top-line study results mid-year.
- The trial is 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. DUR-928 (at doses of 50 mg QD, 150 mg QD or 300 mg BID) is administered orally for 28 consecutive days and patients are followed up for an additional 28 days.
- 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.
POSIMIR® (bupivacaine extended-release solution) Post-Operative Pain Relief Depot. POSIMIR is the Company's investigational post-operative pain relief depot that uses the Company's patented SABER technology and is designed to deliver bupivacaine to provide up to 3 days of pain relief after surgery.
- Since the Anesthetic and Analgesic Drug Products Advisory Committee (AADPAC) meeting on January 16, 2020, we have continued to interact with the FDA as they continue their review of the POSIMIR NDA.
- The efforts to evaluate the program, develop a strategy for filing the response to the Complete Response Letter (CRL), and preparing the response, have been under the direction of Dr. Lee Simon, who was formerly the FDA's Division Director of Analgesic, Anti-inflammatory and Ophthalmologic Drug Products. Dr. Simon also led our preparation efforts for the Advisory Committee meeting.
- POSIMIR has not been approved by the FDA for marketing in the U.S. or elsewhere for any indication and there can be no assurance that the FDA will approve the submission described above.
We will host a conference call today at 4:30 p.m. Eastern Time / 1:30 p.m. Pacific Time to discuss first quarter 2020 results and provide a corporate update:
Monday May 11th @ 4:30pm Eastern Time / 1:30 p.m. Pacific Time
