Recro Pharma Announces Presentation of New Data Demonstrating IV Meloxicam’s Effect on Platelet Function at the 72^nd PostGraduate Assembly in Anesthesiology

MALVERN, Pa., December 10, 2018 (GLOBE NEWSWIRE) — Recro Pharma, Inc. (NASDAQ:REPH), a revenue generating specialty pharmaceutical company focused on therapeutics for the hospital and other acute care settings, today announced a poster presentation highlighting intravenous (IV) meloxicam’s effect on platelet function at the 72^nd PostGraduate Assembly in Anesthesiology (PGA72), sponsored by the New York State Society of Anesthesiologists (NYSSA), taking place December7-11, 2018, in New York City.

The poster, titled “AnEx-vivo Assessment of the Effects of Meloxicam IV on Platelet Function,” which was presented by lead author Jonathan S. Jahr, M.D., David Geffen School of Medicine at UCLA, describes results from anex vivo study assessing the effects of various concentrations of IV meloxicam (5mcg/mL, 10mcg/mL, 15mcg/mL and 20mcg/mL) on platelet function compared to ketorolac (2.5mcg/mL and 5mcg/mL) and an untreated control. The 5mcg/mL concentration of IV meloxicam in this study corresponds to the maximum plasma levels following a 30mg dose in the clinical setting. Similarly, the 5mcg/mL concentration of ketorolac in this study corresponds to a 30mg and the 2.5mcg/mL dose corresponds to the 15mg dose in the clinical setting. In this study, blood samples provided by healthy volunteers (n=8) were analyzed to determine closure time (CT) following the addition of IV meloxicam and ketorolac at the previously mentioned concentrations to the blood plasma samples. The researchers conducted the analyses using a platelet function analyzer(PFA-100), a standard of care for platelet function testing, and two different reagents, collagen with epinephrine (CEPI) and collagen with adenosine diphosphate (CADP).

In the CEPI reagent analysis, a significant treatment effect was observed for changes in CT (p=0.0441). No significant difference was observed in CT for the IV meloxicam treated samples versus the untreated control at any of the evaluated concentrations (p³0.5400). When compared to untreated control, the ketorolac treated sample CT values were significantly prolonged in both the 2.5mcg/mL and the 5mcg/mL concentrations (p£0.0257). All IV meloxicam concentration levels had a significantly shorter CT compared to the 2.5mcg/mL ketorolac concentration (p<0.005). All IV meloxicam concentration levels had numerically shorter CTs compared to the 5mcg/mL ketorolac concentration, though only the 10mcg/mL IV meloxicam concentration reached statistical significance. In the CADP reagent analysis, neither IV meloxicam nor ketorolac demonstrated a significant change in CT versus untreated control (p³0.0907).

“A concern around the use ofnon-steroidal anti-inflammatory drugs (NSAIDs) in the peri- or post-operative setting is the potential for platelet dysfunction and risk of bleeding related events,” commented Dr. Jahr. “Our thesis here was that IV meloxicam’s higher affinity forCOX-2 inhibition, versusCOX-1, would translate into a lower risk for platelet dysfunction. The data presented this year at PGA72 show that IV meloxicam achieved roughly the same closure

times (CTs) as untreated controls and numerically shorter CTs than ketorolac. In contrast, significant CT prolongations were observed in ketorolac samples compared with untreated control. These results suggest that IV meloxicam has the potential to provide a meaningful clinical benefit over ketorolac with respect to a decreased risk of platelet dysfunction.”

“NSAIDs are an integral part of the analgesic toolkit and are the physician’s first-line defense to prevent or treat pain,” said Stewart McCallum, M.D., F.A.C.S., Chief Medical Officer of Recro Pharma andco-author of the poster. “These compelling data continue to build upon the growing body of data supporting IV meloxicam’s safety and reinforce the positive safety findings elucidated by our comprehensive IV meloxicam development program. The IV meloxicam New Drug Application is currently under review by the U.S. Food and Drug Administration and we are currently awaiting our PDUFA goal date of March 24, 2019.”

About IV/IM Meloxicam

Meloxicam is a long-acting, preferentialCOX-2 inhibitor that possesses analgesic, anti-inflammatory and antipyretic activities, which are believed to be related to the inhibition of cyclooxygenase (COX) and subsequent reduction in prostaglandin biosynthesis. IV meloxicam was designed using the NanoCrystal^® platform, a technology that enables enhanced bioavailability of poorly water-soluble drug compounds. NanoCrystal^® is a registered trademark of Alkermes Pharma Ireland Limited (APIL).

About Recro Pharma, Inc.

Recro Pharma is a specialty pharmaceutical company that operates through two business divisions, an Acute Care, hospital product division and a revenue-generating contract development and manufacturing, or CDMO division, located in Gainesville, GA. The Acute Care division is primarily focused on developing innovative products for hospital and other acute care settings. The Company’s lead product candidate is a proprietary injectable form of meloxicam, a long-acting preferentialCOX-2 inhibitor. IV meloxicam has successfully completed two pivotal Phase III clinical efficacy trials, a large double-blind placebo-controlled Phase III safety trial, four Phase II clinical efficacy trials, as well as other safety studies. Recro’s Complete Response to the CRL for IV meloxicam was accepted for filing by the FDA in early October 2018 and assigned a PDUFA date of March 24, 2019. As injectable meloxicam is in thenon-opioid class of drugs, if approved, the Company believes it has the potential to overcome many of the issues associated with commonly prescribed opioid therapeutics, including respiratory depression, constipation, excessive nausea and vomiting, as well as having no addictive potential while maintaining meaningful analgesic effects for relief of pain. The Company’s CDMO division leverages its formulation expertise to develop and manufacture pharmaceutical products using its proprietary delivery technologies and other manufacturing services for commercial and

development-stage partners who commercialize or plan to commercialize these products. These collaborations can result in revenue streams including royalties, profit sharing, research and development and manufacturing fees, which support continued operations for its CDMO division, and it contributesnon-dilutive funding for the development andpre-commercialization activities of its Acute Care division.
