Jazz Pharmaceuticals Clinical Development Pipeline in Narcolepsy and Sleep
Jazz Pharmaceuticals continues to expand its clinical development pipeline in the areas of narcolepsy and sleep. Current clinical investigations include:

• Xyrem® (sodium oxybate) oral solution in Children and Adolescents: In working with the Food and Drug Administration (FDA), Jazz Pharmaceuticals has received a Pediatric Written Request from the FDA to study Xyrem in children and adolescents.  The company is preparing to conduct a Phase 3 clinical trial to assess the safety and efficacy of sodium oxybate in children and adolescents aged seven to 17 years who have narcolepsy with cataplexy.  The company plans to initiate clinical sites for this study in the second half of 2014.
• JZP-110: Jazz Pharmaceuticals is currently planning a Phase 3 clinical development program for this investigational compound for the treatment of EDS in adults with narcolepsy and for the treatment of EDS in adults with obstructive sleep apnea.
• JZP-386: Pre-clinical trials are underway with a deuterium-modified analog of sodium oxybate. Jazz Pharmaceuticals expects the first-in-human study to begin in Europe in 2014, subject to availability of clinical trial material.

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 (EDS) in narcolepsy. Xyrem may only be dispensed to patients enrolled in the Xyrem Success Program. Xyrem was first approved in the U.S. in 2002. Safety and effectiveness in pediatric patients have not been established.

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 CNS 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 Success Program^®, using a centralized pharmacy. Prescribers and patients must enroll in the program. For further information go to www.XYREM.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. Use caution 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. Xyrem is a Schedule III controlled substance. 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). Monitor patients for emergent or increased depression and suicidality and for impaired motor/cognitive function. Episodes of sleepwalking should be fully evaluated and appropriate interventions considered. Consider the amount of daily sodium intake in each dose of Xyrem in patients sensitive to salt intake.

In three controlled clinical trials, the most common adverse reactions (incidence ≥5% and twice the rate of placebo) in Xyrem-treated patients were nausea (20%), dizziness (15%), vomiting (11%), somnolence (8%), enuresis (7%), and tremor (5%).
