CUPERTINO, Calif., Feb. 2, 2021 -- (Healthcare Sales & Marketing Network) -- DURECT Corporation (Nasdaq: DRRX) today announced that the U.S. Food and Drug Administration (FDA) has approved POSIMIR® (bupivacaine solution) for infiltration use 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). Please see important safety information including the Boxed Warning below and the POSIMIR full prescribing information.
"We are excited to announce the approval of POSIMIR, a novel, non-opioid, sustained-release local analgesic for the treatment of post-surgical pain following arthroscopic subacromial decompression surgery," said James E. Brown, President and CEO of DURECT. "This FDA approval provides an important new option to help orthopedic surgeons in their efforts to minimize opioid use while managing acute pain for up to 72 hours after this painful surgery."
"In my experience, POSIMIR was easy to administer into the subacromial space under arthroscopic guidance, where it can directly address the source of postsurgical pain," said Sten Rasmussen, MD CBE PhD, Associate Professor, Department of Orthopaedic Surgery, Aalborg University Hospital, and Professor and Head of the Department of Clinical Medicine, Aalborg University, Denmark, a principal investigator in the POSIMIR registration trial. "A non-opioid product providing up to three days of local analgesia would be a significant benefit to patients."
"The first 72 hours after surgery are typically when patients experience the most severe postsurgical pain," said T J Gan, MD MHS FRCA MBA, Professor and Distinguished Endowed Chair, Department of Anesthesiology at Stony Brook University Renaissance School of Medicine. "So, a new sustained-release product providing continuous analgesia during this critical period is a welcome addition to the armamentarium for anesthesiologists and surgeons, especially as we aim to reduce the use of postsurgical opioids whenever possible."
POSIMIR (bupivacaine solution) for infiltration use is a novel and proprietary product that combines the strength of 660 mg of bupivacaine base with the innovative SABER® platform technology, enabling continuous sustained delivery of a non-opioid local analgesic over 3 days in adults. POSIMIR contains more bupivacaine than any other approved single-dose sustained-release bupivacaine product. At the end of surgery, POSIMIR is administered into the subacromial space under direct arthroscopic visualization, where it continuously releases bupivacaine for 72 hours or more. DURECT is in discussions with potential partners regarding the licensing of commercialization rights to POSIMIR, for which DURECT holds worldwide rights.
About Subacromial Decompression Shoulder Surgery
Subacromial decompression is a type of shoulder surgery used to treat impingement syndrome, a common repetitive-use injury that causes pain when the arm is raised over the head. The procedure is typically performed arthroscopically, meaning that several small incisions are made in the skin and muscle of the shoulder through which a camera lens (arthroscope) and surgical instruments are inserted during surgery. Arthroscopic subacromial decompression is generally considered outpatient surgery, and most patients go home within a few hours of surgery. The recovery period may extend from weeks to months, but the most intense pain typically occurs during the first 3 days after surgery and is often managed with oral opioids. There are over 600,000 surgeries involving arthroscopic subacromial decompression performed each year in the U.S.
In connection with this approval, the Company or its licensee, will be required to conduct two postmarketing non-clinical studies.
Indications and Usage
POSIMIR (bupivacaine solution) for infiltration use is indicated 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.
Limitations of Use
Safety and effectiveness have not been established in other surgical procedures, including soft tissue surgical procedures, other orthopedic procedures, including for intra-articular administration, and boney procedures, or when used for neuraxial or peripheral nerve blockade.

Important Safety Information
BOXED WARNING: Risk of Potential Adverse Embolic Effects Resulting From Inadvertent Intravascaular Injection. Inadvertent intravascular injection could cause POSIMIR droplets to be deposited in the pulmonary and other capillary beds. Administer POSIMIR into the subacromial space at the end of arthroscopic shoulder surgery. Direct arthroscopic visualization must be used to confirm proper placement of the needle tip before injecting POSIMIR.
In POSIMIR clinical studies, no inadvertent intravascular injections were observed. Do not inject POSIMIR intravascularly.
POSIMIR is contraindicated in patients with a known hypersensitivity to any amide local anesthetic, or other components of POSIMIR, as well as in patients undergoing obstetrical paracervical block anesthesia. There is a risk of joint cartilage necrosis with unapproved intra-articular use of POSIMIR. Unintended intravascular injection of POSIMIR may be associated with systemic toxicities, including CNS or cardiorespiratory depression and coma, progressing ultimately to respiratory arrest. As with other local anesthetics, patients should be monitored for central nervous system, cardiovascular, and allergic reactions. Avoid additional use of local anesthetics within 168 hours following administration of POSIMIR. Cases of methemoglobinemia have been reported in association with use of local anesthetics. There have been reports of chondrolysis (mostly in the shoulder joint) following intra-articular infusion of local anesthetics, which is an unapproved use. POSIMIR should be used cautiously in patients with impaired hepatic and cardiovascular function. Adverse events reported with an incidence greater than or equal to 10% and greater than control following POSIMIR administration in shoulder surgery were dizziness, dysgeusia, dysuria, headache, hypoesthesia, paresthesia, tinnitus, and vomiting. Adverse events reported with an incidence greater than or equal to 10% and greater than control following POSIMIR administration in soft tissue surgical procedures were anemia, bradycardia, constipation, C-reactive protein increased, diarrhea, dizziness, dysgeusia, headache, nausea, oropharyngeal pain, post-procedural contusion (bruising), procedural pain, pruritus, pyrexia, somnolence, surgical site bleeding, visible bruising and vomiting.
