About POSIMIR^® (SABER-Bupivacaine)

POSIMIR is an investigational extended-release depot utilizing DURECT's patented SABER technology intended to continuously deliver bupivacaine to the surgical site for 72 hours, to provide up to three days of continuous pain relief after surgery. DURECT is currently conducting PERSIST, a Phase 3 trial in patients undergoing laparoscopic cholecystectomy (gall bladder removal), comparing the effects of POSIMIR to bupivacaine HCl. DURECT expects to complete dosing patients in PERSIST in the second quarter of 2017 and to have top-line results in the fourth quarter of 2017. POSIMIR is a drug candidate under development and has not been approved for commercialization by the U.S. Food and Drug Administration or other health authorities.   

About DURECT

DURECT is a biopharmaceutical company actively developing new therapeutics based on its Epigenetic Regulator Program and proprietary drug delivery platforms.  DUR‑928, a new chemical entity in Phase 1 development, is the lead candidate in DURECT's Epigenetic Regulator Program.  An endogenous, orally bioavailable small molecule, DUR-928 has been shown in preclinical studies to play an important regulatory role in lipid homeostasis, inflammation, and cell survival.  Human applications may include acute organ injury, chronic metabolic diseases such as nonalcoholic fatty liver disease (NAFLD), nonalcoholic steatohepatitis (NASH) and other liver diseases with both broad and orphan populations, and inflammatory skin conditions such as psoriasis.  DURECT's advanced oral, injectable, and transdermal delivery technologies are designed to enable new indications and enhanced attributes for small-molecule and biologic drugs. One late-stage product candidate in this category is POSIMIR^® (SABER^®-Bupivacaine), an investigational locally-acting, non-opioid analgesic intended to provide up to 3 days of continuous pain relief after surgery.  Another late stage product candidate is REMOXY^® ER (oxycodone), an investigational pain control drug based on DURECT's ORADUR^® technology.  For more information, please visit www.durect.com.

DURECT Forward-Looking Statement

The statements in this press release regarding the potential benefits and uses of our drug candidates, including the potential use of POSIMIR to treat post-surgical pain, the anticipated timing of the enrollment of the PERSIST trial and the obtaining of top-line results from that trial, the potential milestone payments and royalties receivable from Sandoz, and the potential use of DUR-928 to treat NAFLD, NASH, other liver diseases, acute organ injury or inflammatory skin diseases such as psoriasis are forward-looking statements involving risks and uncertainties that can cause actual results to differ materially from those in such forward-looking statements. Potential risks and uncertainties include, but are not limited to, the risks that the PERSIST clinical trial of POSIMIR will take longer to conduct than anticipated or result in data that will not support a successful NDA resubmission or product approval, failure to achieve the performance milestones or commercial sales that trigger the referenced payments or royalties, possible adverse events associated with the use of POSIMIR, delays and costs due to additional work or other requirements imposed by regulatory agencies for continued development, approval or sale of POSIMIR, our ability to manufacture, commercialize and obtain marketplace acceptance of POSIMIR, and avoid infringing patents held by other parties and secure and defend patents of our own, and risks related to our ability to obtain capital to fund operations and expenses.
