DURECT Corporation Announces Second Quarter 2021 Financial Results and Update of Programs

CUPERTINO, Calif., July 29, 2021 /PRNewswire/ — DURECT Corporation (Nasdaq: DRRX) today announced financial results for the three months ended June 30, 2021 and provided a corporate update.

Q2 2021 Accomplishments:

We expanded the number of U.S. clinical trial sites to 26 in the Phase 2b AHFIRM clinical study of DUR-928 in severe alcohol-associated hepatitis (AH), and we are enrolling at a good rate. We have now opened about 75% of the U.S. sites we plan to open. We expect to open our first ex-U.S. clinical sites (in the UK, Europe and Australia) in the coming months. In addition, we presented further encouraging DUR-928 clinical data from the completed NASH Phase 1b trial showing trends for reduction in insulin resistance and liver fibrosis biomarkers. Data from a Pharmacokinetic trial in patients with moderate and severe liver impairment showed a reduction in an important apoptosis biomarker with no adverse events or dose-limiting toxicity in these severely ill liver patients. We were also invited to present at the 2021 Epigenetic Therapeutic Targets Virtual Summit, which is for leading companies in the field of Epigenetics to present to their peers. To our knowledge, we were the only presenter utilizing an epigenetic regulator to restore function in injured cells as opposed to most who are using epigenetics to kill cancer cells. Our presentation was well received.

“Executing on the AHFIRM trial to the highest level of quality and in a timely fashion is our highest priority and we are pleased with the progress made this quarter,” stated James E. Brown, D.V.M, President and CEO of DURECT.  “Discussions with potential POSIMIR partners are ongoing.” 

Financial highlights for Q2 2021:

• Total revenues were $2.3 million and net loss was $9.1 million for the three months ended June 30, 2021 as compared to total revenues of $24.5 million and net income of $14.3 million for the three months ended June 30, 2020. Total revenues and net income for the three months ended June 30, 2020 included the recognition of $23.1 million in deferred revenue related to the termination of a license agreement during that period.
• At June 30, 2021, cash and investments were $88.6 million, compared to cash, cash held in escrow and investments of $56.9 million at December 31, 2020. Debt at June 30, 2021 was $20.4 million, compared to $20.8 million at December 31, 2020.

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 alcohol-associated hepatitis (AH) as well as in chronic liver diseases such as non-alcoholic steatohepatitis (NASH).

Clinical Development

Alcohol-associated Hepatitis (AH)

• Enrollment is ongoing in our Phase 2b study in subjects with severe acute AH to evaluate saFety and effIcacy of DUR-928 treatMent (AHFIRM).  AHFIRM is a randomized, double-blind, placebo-controlled, international, multi-center Phase 2b study to evaluate the safety and efficacy of DUR-928 in approximately 300 patients with severe AH.  The study is comprised of three arms targeting enrollment of approximately 100 patients each: (1) Placebo plus standard of care (SOC, which may include the use of methylprednisolone, a corticosteroid, at the discretion of the treating physician); (2) DUR-928 (30 mg); and (3) DUR-928 (90 mg).  All patients in the trial receive supportive care. The primary outcome measure is 90-day survival rate for patients treated with DUR-928 compared to those treated with placebo plus SOC.  The Company is targeting approximately 50 to 60 clinical trial sites in the U.S., U.K., E.U. and Australia.
• Given the high mortality rate in severe AH patients and the absence of an approved therapeutic, we believe demonstration of a robust survival benefit in the AHFIRM trial would support an NDA filing.
• Reflecting the life-threatening nature of AH and the lack of therapeutic options for this devastating condition, the FDA granted DUR-928 Fast Track Designation for the treatment of AH in December 2020.
• In March 2021, a peer-reviewed research paper describing the binding sites and proposed mechanism of action of DUR-928 was published in The Journal of Lipid Research. The publication shows that DUR-928 (referred to in the paper as 25HC3S) binds to and inhibits the activity of DNA methyltransferases (DNMTs) DNMT-1, 3a and 3b, epigenetic regulating enzymes that add methyl groups to DNA (a process called DNA methylation). As such, by inhibiting DNMT activity, DUR-928 inhibits DNA methylation, thereby regulating the expression of genes that modulate crucial cellular activities, including those associated with cell death, stress response, and lipid biosynthesis. These modulations may lead to improved cell survival, and reduced lipid accumulation and inflammation, as has been observed in various in vivo animal models and in results from DURECT’s completed clinical trials in alcohol-associated hepatitis (AH) and non-alcoholic steatohepatitis (NASH).
• In July 2021 we presented DUR-928’s mechanism of action, the previously reported positive results from our Phase 2a clinical study in alcohol-associated hepatitis (AH), and an overview of the AHFIRM trial at the 2021 Epigenetic Therapeutic Targets Virtual Summit.
• In the 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.
• Alcohol-associated hepatitis (also called alcoholic hepatitis or 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 a recent onset of 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 approximately 132,000 hospitalizations for patients with AH in 2018. From a 2018 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 $875,000 per patient. 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 and 29% at 90 days after admission.

Non-Alcoholic Steatohepatitis (NASH)

• In June 2021, we presented new data showing additional signals of potential efficacy from the NASH Phase 1b study of DUR-928 at the 2021 International Liver Conference (EASL) . This was a randomized and open-label clinical study conducted in the U.S. to evaluate safety, pharmacokinetics and signals of biological activity of DUR-928 in NASH patients with stage 1-3 fibrosis. Subjects in the 50 mg and 150 mg groups had 22% and 18% median reductions (not statistically significant) of homeostatic model assessment (HOMA-IR) from baseline, respectively, after 4 weeks of daily oral dosing of DUR-928. NASH subjects also had improvement from baseline in liver stiffness, assessed by transient elastography (TE), magnetic resonance elastography (MRE) and the liver fibrosis marker pro-C3. Positive topline results from this study were previously reported in May 2020.
• We have also conducted a Phase 1b open-label, multi-center U.S. study to evaluate the safety, tolerability, and pharmacokinetics (PK) of DUR-928 in subjects with moderate (Child-Pugh B scores, n=10) and severe (Child-Pugh C scores, n=7) hepatic function impairment (HI), and matched control subjects (MCS, n=10) with normal hepatic functions. Each subject received a single oral dose of 200 mg DUR-928. Results from this study were presented at the International Liver Conference 2021 (EASL) in June 2021. DUR-928 was safe and well-tolerated by all moderate and severe HI subjects with no adverse events and no dose-limiting toxicity reported throughout the study. As expected, clearance of DUR-928 was decreased in HI subjects compared to MCS with normal hepatic function, resulting in a 4-10 fold higher drug exposure (Cmax and AUC) in HI subjects. Additionally, a single oral dose of 200 mg of DUR-928 in subjects with HI resulted in statistically significant median reductions from baseline of the apoptosis biomarker M30 (cCK-18) at 12 hours post-dose.
• We are working with a number of disease experts to determine next steps for DUR-928 in NASH.

POSIMIR^® (bupivacaine solution) Post-Operative Pain Relief Depot.  POSIMIR is DURECT’s post-operative pain relief depot that uses the Company’s patented SABER® technology that delivers bupivacaine to provide up to 3 days of post-surgical analgesia.

• In February 2021, POSIMIR was granted U.S. FDA approval in adults for administration into the subacromial space under direct arthroscopic visualization to produce post-surgical analgesia for up to 72 hours following arthroscopic subacromial decompression.
• The approval was based on positive data from a randomized, multicenter, assessor-blinded, placebo–controlled clinical trial in patients undergoing arthroscopic subacromial decompression surgery with an intact rotator cuff. The primary outcome measures were mean pain intensity and total opioid rescue analgesia administered, both evaluated over the first 72 hours after surgery versus placebo. POSIMIR demonstrated a statistically significant improvement in both primary outcome measures: a 1.3 point, or 20%, reduction in mean pain intensity on a 0-10 point pain scale (p=0.01), and a 67% reduction in I.V. morphine-equivalent rescue opioid use, from a median of 12 mg in the placebo group to 4 mg in the POSIMIR group (p=0.01). In connection with this approval, the Company or its licensee, will be required to conduct two postmarketing non-clinical studies. Full Prescribing Information, including the Boxed Warning, is available at www.POSIMIR.com.
• DURECT is in discussions with potential commercial partners for POSIMIR, for which DURECT currently holds worldwide rights.

Debt Amendment.  In May 2021, the Company amended its existing $20 million term loan with Oxford Finance such that principal payments will commence 18 months later than previously scheduled (i.e., commencing June 1, 2023 rather than December 1, 2021) and the final maturity date has been moved back by 16 months (i.e., from May 1, 2024 to September 1, 2025). The interest rate and final payment remain unchanged, and the Company paid Oxford Finance an amendment fee of $712,500.
