Twelve Jazz-Sponsored Oral and Poster Presentations To Be Presented

DUBLIN, Ireland, May 24, 2017 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) announced today that twelve abstracts supporting the company's sleep medicine portfolio, including data on its investigational compound JZP-110, data on the investigational use of sodium oxybate for the treatment of cataplexy and excessive daytime sleepiness in pediatric patients with narcolepsy, and data from the Nexus narcolepsy patient registry, will be presented at the 31^st Associated Professional Sleep Societies (APSS) Annual SLEEP Meeting June 3-7 in Boston, MA.  

"Developing innovative treatments for often overlooked and debilitating conditions is one of our highest priorities," said Karen Smith, M.D., Ph.D., executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals.  "The breadth of data that we will be presenting at the SLEEP 2017 meeting reflects our ongoing commitment to advancing meaningful treatments that address unmet needs in sleep medicine, including for patients living with narcolepsy and obstructive sleep apnea (OSA)."

Key presentations include data from the Treatment of OSA and Narcolepsy Excessive Sleepiness (TONES) Phase 3 program for JZP-110, an investigational wake-promoting agent in development for the treatment of excessive sleepiness in adult patients with narcolepsy (TONES 2) or OSA (TONES 3 and TONES 4), Phase 2/3 data from a clinical study evaluating sodium oxybate in pediatric patients aged 7-17, and new data from the Jazz-sponsored Nexus Narcolepsy Registry, the first narcolepsy-specific, web-based registry of patient-reported data.

About JZP-110
JZP-110 is a selective dopamine and norepinephrine reuptake inhibitor (DNRI) in late-stage development for treatment of excessive sleepiness in adult patients with narcolepsy or OSA.  In 2014, Jazz Pharmaceuticals acquired a world-wide license (except in certain countries in Asia) to develop and commercialize JZP-110 from SK Biopharmaceuticals, which discovered the compound.  Jazz Pharmaceuticals has worldwide development, manufacturing, and commercialization rights to JZP-110, excluding certain jurisdictions in Asia.  SK Biopharmaceuticals maintains rights in Korea, Japan, China, Taiwan, Singapore, Indonesia, India, Philippines, Thailand, Malaysia, Vietnam, and Hong Kong.  JZP-110 has orphan drug designation in the United States for narcolepsy.  

Across the entire JZP-110 development program, over 2,000 subjects have enrolled in 20 studies. The JZP-110 Phase 3 clinical program includes one study evaluating excessive sleepiness in adult patients with narcolepsy (TONES 2), two studies evaluating excessive sleepiness in adult patients with OSA (TONES 3 and TONES 4), and an open-label, long-term safety and maintenance of efficacy study (TONES 5).  Enrollment is complete in all studies that are expected to support Jazz Pharmaceuticals' planned JZP-110 New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA) in late 2017.

About Xyrem
Xyrem® (sodium oxybate) oral solution, CIII, is indicated for the treatment of cataplexy in narcolepsy and for the treatment of excessive daytime sleepiness in narcolepsy.  Xyrem may only be dispensed to patients enrolled in the Xyrem REMS Program.  Xyrem was first approved in the U.S. in 2002, based on clinical trial data in adults.  The current United States Product Insert for Xyrem indicates that safety and effectiveness in pediatric patients have not been established.  Jazz plans to submit a supplemental NDA to FDA in the fourth quarter of 2017 with revised proposed labeling to include data for use in pediatric patients, consistent with the FDA's pediatric written request.

IMPORTANT SAFETY INFORMATION

Xyrem is a central nervous system (CNS) depressant. In clinical trials at recommended doses obtundation and clinically significant respiratory depression occurred in Xyrem-treated patients. Almost all of the patients who received Xyrem during clinical trials in narcolepsy were receiving central nervous system stimulants.

Xyrem is the sodium salt of gamma hydroxybutyrate (GHB). Abuse of GHB, either alone or in combination with other CNS depressants, is associated with CNS adverse reactions, including seizure, respiratory depression, decreases in the level of consciousness, coma, and death.

Because of the risks of CNS depression, abuse, and misuse, Xyrem is available only through a restricted distribution program called the Xyrem REMS Program, using the central pharmacy that is specially certified. Prescribers and patients must enroll in the program. For further information go to www.XYREMREMS.com or call 1-866-XYREM88® (1-866- 997-3688).

Xyrem is contraindicated in combination with sedative hypnotics or alcohol and in patients with succinic semialdehyde dehydrogenase deficiency. 

Caution should be used when considering the concurrent use of Xyrem with other CNS depressants.  Healthcare providers should caution patients against hazardous activities requiring complete mental alertness or motor coordination within the first 6 hours of dosing or after first initiating treatment until certain that Xyrem does not affect them adversely. The rapid onset of sedation, coupled with the amnestic features of Xyrem, particularly when combined with alcohol, has proven to be dangerous for the voluntary and involuntary user (e.g. assault victim). Patients should be monitored for emergent or increased depression and suicidality and for impaired motor/cognitive function.  Episodes of sleepwalking should be fully evaluated and appropriate interventions considered.  The amount of daily sodium intake in each dose of Xyrem should be considered in patients sensitive to salt intake. The most common adverse reactions were nausea, dizziness, vomiting, somnolence, enuresis, and tremor.
