DURECT Corporation Announces Second Quarter 2017 Financial Results and Provides Corporate Update

CUPERTINO, Calif., Aug. 8, 2017 /PRNewswire/ -- DURECT Corporation (Nasdaq: DRRX) today announced financial results for the three months ended June 30, 2017 and provided a corporate update.  

• Executed a U.S. commercialization agreement with Sandoz for POSIMIR^®, including a $20 million upfront payment, as well as milestone payments and double digit royalties.
• Total revenues were $4.3 million and net loss was $9.9 million for the three months ended June 30, 2017 as compared to total revenues of $3.2 million and net loss of $9.0 million for the three months ended June 30, 2016.
• At June 30, 2017, cash and investments were $33.6 million, compared to cash and investments of $25.2 million at December 31, 2016. Cash and investments increased during the quarter primarily as a result of the upfront payment received from Sandoz in connection with our POSIMIR agreement. Debt at June 30, 2017 was $19.9 million.

"Highlights of the second quarter included reaching agreement with Sandoz to commercialize POSIMIR in the United States and completing ahead of schedule the enrollment of PERSIST, the POSIMIR pivotal Phase 3 clinical trial in post-operative pain," stated James E. Brown, D.V.M., President and CEO of DURECT.  "We completed drug-drug interaction studies with DUR-928, the lead molecule in our Epigenetic Regulator Program, and found no evidence of likely drug interactions.  We also completed a second Phase 1b study in which we observed that DUR-928 was well tolerated in moderate to severe kidney function impaired patients and that the pharmacokinetics were comparable among the patients and matched control subjects.  In addition, we were pleased that Orient Pharma, our licensee in certain Asian and South Pacific countries, has achieved positive top-line results from a Phase 3 clinical study of ORADUR-Methylphenidate ER conducted in Taiwan."  

Update on Selected Programs:

POSIMIR (SABER^®-Bupivacaine) Post-Operative Pain Relief Depot.  POSIMIR is our investigational post-operative pain relief depot that utilizes our patented SABER technology and is designed to deliver bupivacaine to provide up to 3 days of pain relief after surgery.    

• In May 2017, we signed a development and commercialization agreement with Sandoz AG covering the United States. Under the terms of the agreement, Sandoz has made an upfront payment to DURECT of $20 million, with the potential for up to an additional $43 million in development and regulatory milestones, up to an additional $230 million in sales-based milestones, as well as a tiered double digit royalty on product sales in the United States. DURECT will remain responsible for the completion of the PERSIST Phase 3 clinical trial for POSIMIR as well as FDA interactions through approval.
• In June 2017, we completed enrolling 296 patients in Part 2 of PERSIST, a POSIMIR Phase 3 clinical trial consisting of patients undergoing laparoscopic cholecystectomy (gallbladder removal) surgery. We expect to complete patient follow-up visits in the third quarter and to announce top-line results from PERSIST in the fourth quarter of this year.

Epigenetic Regulator Program. DUR-928, the lead product candidate in our Epigenetic Regulator Program, is an endogenous, small molecule, new chemical entity (NCE), which may have broad applicability in several metabolic diseases such as nonalcoholic steatohepatitis (NASH) and other disorders of the liver, in acute organ injuries such as acute kidney injury, and in autoimmune/inflammatory skin disorders such as psoriasis.

Oral Administration

• We recently conducted in vivo drug-drug interaction (DDI) studies with both orally administered and IV injected DUR-928. The results demonstrate that DUR-928 did not have effects on the safety and pharmacokinetics (PK) of midazolam, a drug used for detecting drug-drug interactions via the enzyme CYP3A4. This enzyme is commonly associated with causing many clinically relevant drug-drug interactions. These data will be included in upcoming INDs submitted to the FDA.
• We are actively working towards initiating a Phase 2 trial in primary sclerosing cholangitis (PSC), with orally administered DUR-928. PSC is a chronic liver disease characterized by a progression of cholestasis (decrease in bile flow) with inflammation and fibrosis of bile ducts. We recently applied for and have received orphan drug designation for PSC with DUR-928.

Injectable Administration

• We recently completed a Phase 1b study in Australia with DUR-928. This was an open-label, single-ascending-dose study investigating safety and PK in patients with impaired kidney function (stage 3 and 4 chronic kidney disease) and matched control subjects.
• This study was conducted in successive cohorts evaluating single-dose levels (first a low dose and then a high dose which was four times larger than the low dose cohort) of DUR-928 administered by intramuscular injection. The low dose cohort enrolled 6 kidney function impaired patients and 3 matched control subjects, and the high dose cohort enrolled 5 kidney function impaired patients and 3 matched control subjects.
• In this trial, DUR-928 was well tolerated among all subjects and the PK parameters between the kidney function impaired patients and the matched control subjects were comparable.
• We are working closely with expert advisors to design Phase 2 trials in one or more indications with an injectable formulation of DUR-928.

Topical Administration

• As previously disclosed, we completed an exploratory Phase 1b trial in psoriasis patients (n = 9 evaluable patients) utilizing intralesional micro injections of DUR-928; promising activity was observed which we believe warrants further investigation.
• In the first half of 2017, we developed several topical formulations of DUR-928 that we expect to utilize in a future topical application psoriasis trial. We believe that there is a large unmet medical need for new topical drugs for inflammatory skin diseases such as psoriasis and atopic dermatitis.

REMOXY^® ER (oxycodone) Extended-Release Capsules CII.  Based on our ORADUR technology, the investigational drug REMOXY ER is a unique long-acting formulation of oxycodone designed to discourage common methods of tampering associated with opioid misuse and abuse.  In March 2017, Pain Therapeutics announced that it plans to resubmit the REMOXY ER NDA after completing two additional studies regarding REMOXY ER based on guidance obtained in a recent meeting with the FDA.  The two studies are a clinical abuse potential study via the intranasal route of abuse and a non-clinical abuse potential study using household solvents.  Pain Therapeutics stated that it expects to complete these studies by year end 2017, after which it intends to have a pre-NDA meeting with the FDA followed by resubmission of the REMOXY NDA.

ORADUR-ADHD Program.  ORADUR-Methylphenidate ER is an investigational drug that has the potential for rapid onset of action and long duration with once-a-day dosing, utilizes a small capsule size relative to the leading existing long-acting products on the market and incorporates our ORADUR anti-tampering technology.  Orient Pharma, our licensee in defined Asian and South Pacific countries, has reported that a Phase 3 study conducted in Taiwan has achieved positive results.  We retain rights to all other markets in the world, notably including the U.S., Europe and Japan.  We intend to reach out with these Phase 3 data to potential development and commercialization partners for major markets not licensed to Orient Pharma.
