The prevalence of OSAS in Western countries is around 4% in middle-aged men and around 2% in middle-aged women. Incidence is increasing as the incidence of obesity is increasing. OSAS is highly prevalent in persons with type 2 diabetes and related metabolic conditions such as insulin resistance and glucose intolerance [1].

Mar 17 · Results of 2 PIII studies TONES 3 and TONES 4 (n=602) found JZP-110, showed statistically significant differences in co-primary efficacy endpoints of MWT and ESS vs. placebo [5].

Sep 16 · Jazz Pharmaceuticals completes enrolment in a PIII randomised, double-blind, withdrawal trial that is assessing safety and efficacy of JZP-110, in the treatment of excessive daytime sleepiness (EDS) in patients with sleep apnoea syndrome (NCT02348619). The trial is a six-week, flexible-dose study. Maintenance of wakefulness test (MWT) and change in the Epworth sleepiness scale (ESS), assessed at six weeks, is the defined co-primary endpoint of the trial. Both are validated endpoints that measure severity of excessive sleepiness and ability to stay awake in patients. The trial has enrolled 200 patients in the US, Finland, France, Germany, and Sweden [3].

Sep 16 · Another open-label PIII trial is assessing long-term safety and maintenance of efficacy of JZP 110 in 450 patients with narcolepsy and sleep apnoea syndrome in the US, Canada, Finland and Germany (NCT02348632; EudraCT2014-005489-31) [3].

Sep 16 · Jazz Pharmaceuticals completes enrolment in the PIII (NCT2348606) study, and collection of primary outcome data. It has assessed four doses of JZP 110 or placebo over a 12-week period [2,3].

May 15 · PIII study evaluating safety and efficacy of JZP 110, for treatment of excessive sleepiness in adult patients with obstructive sleep apnoea (OSA) syndrome (NCT02348606; EudraCT2014-005514-31) starts.. Maintenance of wakefulness test (MWT) and change in the Epworth sleepiness scale (ESS), assessed at six weeks, is the defined co-primary endpoint of the trial. Both are validated endpoints that measure severity of excessive sleepiness and ability to stay awake in patients. The double-blind, placebo-controlled, multiple-centre trial will enrol 440 patients in the US, Canada and Germany [2].

Prevalence is estimated as 25 per 100,000 in Caucasian populations. Age of onset is typically around adolescence. A smaller number of cases presents at around 35 years. Less than 5% of narcolepsy with cataplexy occurs in children. One study found that it was often linked to complex movement disorders. It is possible that incidence statistics would increase if diagnostic features were recognised at an earlier age [1].

May 15: Jazz Pharmaceuticals initiates a PIII TONES-002 study to evaluate safety and efficacy of JZP 110 for treatment of EDS in patients with narcolepsy (NCT02348593). The 12-week, randomised, double-blind, placebo-controlled, 4-treatment parallel group study is designed to enrol approximately 240 patients in the US, Canada, Finland and Germany. Primary outcome is change in mean sleep latency time (in minutes) as determined from the first four trials of a 40-minute MWT from Baseline to Week 12. Collection of primary outcome data expected Sep 16 [2,3].

---

Jun 17: topline results of the TONES-2 study presented as a conference poster - they showed dose-related improvements in both co-primary endpoints (mean sleep latency and the Epworth Sleepiness Scale, ESS), with p<0.0001 for 150 mg and 300 mg doses; improvement with 75 mg dose was statistically significant (p<0.05) for ESS only. The higher doses also showed statistically significant improvement in the main secondary outcome. JZP-110 was generally well tolerated [5].
