DUBLIN, Sept. 26, 2016 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that patient enrollment has been completed for its two Phase 3 studies evaluating JZP-110 in excessive sleepiness (ES) associated with obstructive sleep apnea (OSA).
"We are pleased to have reached this important milestone in our Phase 3 program," said Karen Smith, M.D., Ph.D., global head of research and development and chief medical officer of Jazz Pharmaceuticals. "We look forward to reporting the top-line results from the two OSA studies in the first quarter of 2017."
The two Phase 3 OSA studies enrolled approximately 654 patients. Both studies were double-blind, placebo-controlled, multiple-center studies evaluating the safety and efficacy of JZP-110 in the treatment of ES in adult patients with OSA. Study 14-003 evaluated four doses of JZP-110 or placebo for a 12-week period and study 14-004 was a six-week, flexible-dose, randomized withdrawal study. The studies have co-primary endpoints of the Epworth Sleepiness Scale (ESS) and the Maintenance of Wakefulness Test (MWT). These are validated endpoints, used in clinical practice, to measure the severity of excessive sleepiness and ability to stay awake in patients.
JZP-110 is a selective dopamine and norepinephrine reuptake inhibitor (DNRI) in late-stage development for treatment of ES in adult patients with narcolepsy or OSA. Jazz Pharmaceuticals has worldwide development, manufacturing, and commercialization rights to JZP-110, excluding certain jurisdictions in Asia. JZP-110 has orphan drug designation in the United States for narcolepsy. The JZP-110 clinical program includes two additional studies: the Phase 3 safety and efficacy study evaluating JZP-110 for the treatment of ES in narcolepsy and the open label long-term safety study. Enrollment in these studies is ongoing.
