DURECT and Innocoll Announce a $136 Million U.S. Licensing Agreement for POSIMIR® (Bupivacaine Solution)

CUPERTINO, Calif. and ATHLONE, Ireland, Dec. 22, 2021 /PRNewswire/ -- DURECT Corporation (Nasdaq: DRRX) today announced a licensing agreement granting Innocoll Biotherapeutics plc, a specialty pharmaceutical company and portfolio business of Gurnet Point Capital, exclusive development and commercialization rights to POSIMIR® (bupivacaine solution) for infiltration use, DURECT's FDA-approved non-opioid, sustained-release local analgesic for the treatment of post-surgical pain in adults following arthroscopic subacromial decompression surgery, in the United States.

"We are excited to license the U.S. development and commercialization rights for POSIMIR to Innocoll, whose dedicated hospital sales and marketing organization is deeply committed to providing non-opioid analgesia products to patients in the post-surgical setting," said James E. Brown, President and Chief Executive Officer of DURECT Corporation. "Completing this POSIMIR deal is another important step in the continued transformation of DURECT as we continue to focus on larsucosterol, our lead epigenetic regulator, which is in late-stage clinical development for alcohol-associated hepatitis."

"We believe that POSIMIR has the potential to become a cornerstone of multi-modal post-operative pain management as well as an important contributor to the on-going efforts to provide safe and effective alternatives to opioid-based medications following surgery," added Louis Pascarella, Chief Executive Officer of Innocoll. "Innocoll is now the only company with two bupivacaine-based, sustained-release, non-opioid products, that are FDA approved and indicated for relief of post-surgical pain in specified surgical procedures. We are currently on track to launch POSIMIR in the second quarter of 2022, subject to commercial supply timelines."

Terms of the Collaboration

Under the terms of the agreement, Innocoll will make near-term payments to DURECT of $6 million, consisting of a $4 million license fee and a $2 million payment upon first commercial sale, with the potential for up to an additional $130 million in commercial, regulatory and intellectual property milestone payments as well as tiered, low to mid double-digit royalties on net product sales in the United States.

Innocoll has been granted the exclusive right to develop and commercialize POSIMIR in the United States.  Innocoll has also been granted the right to conduct additional development activities to expand the approved indications for POSIMIR, and DURECT's contract manufacturing supply agreement for POSIMIR has been assigned to Innocoll. DURECT retains all commercial rights to POSIMIR throughout the rest of the world.

About POSIMIR

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. 

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.

Full Prescribing Information, including the Boxed Warning, is available at www.POSIMIR.com

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.
