Javelin Pharmaceuticals Announces Successful Pivotal Phase 3 Trial,Data

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jun 19, 2007 - Javelin Pharmaceuticals (AMEX: JAV) announced today that its product candidate Rylomine(TM) (intranasal morphine) successfully met its primary clinical endpoint, the Sum of the Pain Intensity Difference (SPID) scores over 0-24 hours postoperatively. In this first of two pivotal Phase 3 studies, patients with moderate-to-severe pain after elective orthopedic surgery were given 7.5 mg Rylomine every hour as needed, 15 mg Rylomine every 3 hours as needed, or 7.5 mg intravenous (IV) morphine every 3 hours as needed. Patients in each of the three active treatment groups had significantly better (p less than .01 or less) SPID scores over 24 hours than the corresponding placebo groups.

"Parenteral morphine is the gold standard for postoperative analgesia," commented Dr. Daniel B. Carr, CEO and CMO of Javelin Pharmaceuticals. "Today's gratifying results extend our prior positive study findings showing that Rylomine is a simple, effective alternative to more complex, cumbersome and costly methods of postoperative opioid analgesia. We look forward to continuing the development of this innovative product candidate."

There were no serious adverse events related to the study drug. Local adverse events associated with nasal administration (bad taste, throat irritation, instillation site reaction, nasal erythema, nasal irritation) were more common with Rylomine or intranasal placebo than the intravenous morphine groups. General systemic adverse events related to active drug were similar across morphine treatment groups regardless of route of administration and consistent with morphine's known pharmacologic effects (dizziness, nausea, transient decreased oxygen saturation, and vomiting).

Full analyses of the data are ongoing and will be reported when available.

About the Study

This study, termed MOR-003, involved 278 randomized patients with moderate to severe post-surgical pain enrolled at 7 sites in the United States. These patients received either 7.5 mg Rylomine every hour as needed, 15 mg Rylomine every three hours as needed, 7.5 mg IV morphine, or matching placebos. In this "blinded" study, patients received treatments of which the identity (active or placebo) was not known by either the Investigator or the patient, although patients did know whether they were receiving intravenous or intranasal treatment.

About Rylomine(TM)

Rylomine is a patient-controlled nasal spray that delivers a single metered dose of morphine, an opioid analgesic used for the treatment of moderate-to-severe pain. After use, a negligible amount of morphine remains in the dispenser, reducing the risk of scavenging and abuse of discarded devices. Data from clinical studies have demonstrated that Rylomine has similar efficacy to an infusion of intravenous morphine.

Parenteral morphine is the standard of care for management of acute moderate-to-severe pain, especially after surgery, when analgesic requirements vary between individuals and often fluctuate even in the same patient. IV morphine analgesia has rapid onset, proven efficacy, can accommodate variations in analgesic demand, and has side effects that are well understood by medical personnel. Morphine, like many drugs, is poorly absorbed across mucosal barriers and, in particular, the nasal membrane. Javelin's proprietary technology allows for nasal delivery of predictable therapeutic blood levels of morphine. The key to this technology is ChiSys(TM), a carbohydrate polymer that, while pharmaceutically inert by itself, enhances the absorption of compounds across mucosal membranes, such as in the nasal cavity. The contribution of ChiSys(TM) to enhancing mucosal drug absorption reflects several factors including its potent mucoadhesive property, which prevents drug washout. Rylomine is a novel formulation of morphine and ChiSys(TM) packaged in a single unit-dose nasal spray. Worldwide, no comparable formulation of morphine is available.
