Jazz Initiates Phase III Study for Narcolepsy Candidate

Read MoreHide Full Article

Jazz Pharmaceuticals plc (JAZZ - Free Report) recently announced the initiation of patient enrollment in a phase III study evaluating the efficacy and safety of its pipeline candidate, JZP-258, for the potential treatment of adult narcolepsy patients with cataplexy and excessive daytime sleepiness (EDS).

JZP-258 is an oxybate product candidate with 90% less sodium content than its marketed product Xyrem (sodium oxybate). Xyrem is currently approved for narcolepsy with cataplexy and EDS and, at the highest approved dose of 9 grams per night, contains 1,640 mg of sodium.

Jazz’s shares have traded above the Zacks classified Medical-Drugs industry so far this year. Specifically the company’s shares gained 27.3% while the industry registered an increase of 3.9%.





The phase III study is a double-blind, placebo-controlled, randomized-withdrawal, multicenter study. It is mainly initiated to reduce sodium intake in narcolepsy patients. The study is expected to achieve clinically meaningful goals as patients with narcolepsy are at risk for high sodium intake-related consequences, including hypertension and other cardiovascular diseases. The study is expected to enroll approximately 185 patients in order to randomize around 130 patients.

The study will be conducted across approximately 60 centers in the EU and the U.S.

We note that JZP-258 was earlier evaluated in a phase I study in 60 healthy adults, which demonstrated a safety profile similar to Xyrem. However, the company expects JZP-258 to offer more meaningful clinical benefit to patients than Xyrem.

Per the company’s press release one in 2,000 people in the U.S. is affected by narcolepsy, with symptoms typically appearing in early adulthood. Estimates show that 50% or more narcolepsy patients remain undiagnosed for as long as 10 years. Hence, timely approval of the drug will provide the company to reach out to a huge number of patients affected with the disease.
