Innocoll AG Announces First Patient Dosed in the XaraColl MATRIX-2 Phase 3 Study for the Treatment of Postoperative Pain

ATHLONE, Ireland - Innocoll AG (NASDAQ:INNL), a global, commercial-stage, specialty pharmaceutical company that develops, manufactures and supplies a range of pharmaceutical products and medical devices using its proprietary collagen-based technologies, today announced that the first patient was dosed in the MATRIX-2 (Multisite Assessment of PosToperative PainReduction wIth XaraColl) Phase 3 study for the treatment of postoperative pain following open hernioplasty with mesh using XaraColl, Innocoll's surgically implantable and bioresorbable bupivacaine-collagen matrix.

The MATRIX-2 Phase 3 study is the second of two identical randomized, placebo-controlled, double-blinded studies to investigate the safety and efficacy of a surgically implantable and resorbable bupivacaine-collagen matrix. The MATRIX-1 study had its first patient enrolled last month. Each study is expected to enroll approximately 300 patients aged 18 and older in the United States. Patients with a unilateral inguinal hernia undergoing open hernioplasty with mesh placement will be treated in one of two arms per study: three 100 mg XaraColl matrices for a total dose of 300 mg of bupivacaine hydrochloride or three placebo matrices. The matrices are placed at the site of the hernia repair in order to provide local levels of bupivacaine directly at the location of surgical trauma.

The primary efficacy endpoint is the sum of pain intensity difference (SPID) over 24 hours comparing the XaraColl matrix to placebo. Additional endpoints include the SPID at 48 and 72 hours as well as total opioid use at 24, 48 and 72 hours. Safety will be evaluated through the collection of adverse events through 30 days postoperatively.

Enrollment for both studies is expected to complete in the first quarter of 2016 and topline results from the studies are expected in the second quarter of 2016.

Postoperative pain management is a serious concern for surgeons and patients. In the U.S., approximately 750,000 hernia operations are performed annually. Effective postoperative pain control is an essential component of the care of the surgical patient. Inadequate pain control, apart from being inhumane, may result in increased morbidity or mortality. While opioids are very effective analgesics, opioids also carry with them many undesirable potential side effects: sedation, respiratory depression, nausea and vomiting, hypotension and bradycardia, pruritus, and inhibition of bowel function.

XaraColl acts locally following implantation at the surgical site to provide sustained pain relief by delivering appropriate concentrations of bupivacaine directly at the site of surgical trauma for up to 72 hours. Bupivacaine is a long acting local anesthetic with a well-characterized safety and efficacy profile. The XaraColl collagen matrix helps deliver that local pain relief for up to 72 hours.

"We remain committed to delivering our late-stage portfolio and realizing the potential of these exciting therapeutics for the physicians and patients they serve," said Tony Zook, Chief Executive Officer. "With the dosing of the first patient in our MATRIX-2 study, we continue to execute on the deliverables we set for ourselves. Both the Cogenzia and XaraColl Phase 3 programs are fully underway and before the close of the year, we also hope to have discussions with the FDA to advance CollaGuard."
