March 20, 2017: Jazz Pharmaceuticals announced positive efficacy results from two global multicenter studies in adult patients with excessive sleepiness associated with obstructive sleep apnea (OSA). JZP-110 demonstrated highly statistically significant differences in the co-primary efficacy endpoints in the TONES 3 study at the 300 mg, 150 mg, 75 mg and 37.5 mg dose arms and in the TONES 4 study in the combined JZP-110 treatment arm (300 mg, 150 mg, and 75 mg doses) compared to placebo. Based on the preliminary safety analysis, the most commonly reported adverse events (AEs) in these studies were consistent with those previously described in the Phase 2 clinical studies evaluating JZP-110 in narcolepsy.
The Treatment of OSA and Narcolepsy Excessive Sleepiness (TONES) Phase 3 program is comprised of four studies, two in OSA, one in narcolepsy and one open-label, long-term safety and maintenance of efficacy study. The two Phase 3 OSA studies enrolled 652 total patients.
Efficacy Results of TONES 3 Study The TONES 3 study, or 14-003, is a 5-arm, parallel-group study evaluating four doses of JZP-110 (300 mg, 150 mg, 75 mg and 37.5 mg) and placebo for a 12-week period. The study enrolled 476 patients and was powered to detect differences between placebo and the 300 mg and 150 mg dose arms.
In TONES 3, JZP-110 demonstrated highly statistically significant improvement in the co-primary endpoints of Maintenance of Wakefulness test (MWT) and Epworth Sleepiness scale (ESS) at all doses. In addition, the key secondary endpoint of Patient Global Impression of Change (PGIc) scale demonstrated a highly statistically significant improvement in the 300 mg, 150 mg and 75 mg doses versus placebo. On the co-primary endpoints of MWT and ESS, the study demonstrated that treatment with JZP-110 significantly increased the patients’ ability to stay awake and significantly decreased patients’ subjective levels of sleepiness, respectively, compared to placebo. These effects were maintained throughout the course of the study.
Efficacy Results of TONES 4 Study The TONES 4 study, or 14-004, is a six-week study in which eligible subjects received four weeks of open-label treatment, and at the end of week 4, 126 patients who reported “much” or “very much” improvement on the PGIc scale and who had numerical improvements on the MWT and ESS at week 4 were then randomized 1:1 to receive either the same dose of JZP-110 received in the stable dose phase, or placebo, for two weeks in the randomized withdrawal phase.
In TONES 4, patients randomized to continue on JZP-110 maintained efficacy, while those randomized to placebo experienced a loss of efficacy, as measured by the co-primary and key secondary endpoints.
Preliminary Safety Results of TONES 3 and TONES 4 Studies Based on a preliminary safety analysis, the most commonly reported adverse events were headache, nausea, decreased appetite, dry mouth, anxiety, dizziness, insomnia, nasopharyngitis, and palpitations. There were six patients with serious adverse events (SAEs), two patients on placebo and four on JZP-110. None of these was deemed a treatment-related adverse event as assessed by the investigators. Additional safety information will be available based on the final analyses of the JZP-110 program, including results of the open-label, long-term safety and maintenance of efficacy study.
January 18, 2017: Leerink reiterates their Outperform rating on Jazz Pharmaceuticals and sets a price target of $182 after yesterday evenings FDA updates regarding a generic Xyrem (naracolepsy) application appear to be a net-positive for JAZZ as the FDA concurrently ruled (in a citizens petition [CP]) that it won’t allow generic substitutes to carve-out safety/dosing language that is patent protected. At a minimum, firm expects the approved generic will need to successfully litigate the Xyrem formulation (ends mid-2020E) and DDI patents (expires 2033E) before launching as they believe an at-risk launch against two battletested patent families would be financial catastrophic. Ultimately, todays update provides much needed visibility into how the FDA views the safety risk of omitting divalproex DDI (drug-drug interaction) and dosing language from the Xyrem package insert. Some investors believed generic companies’ ability to “carve out” the DDI information from their labels would allow them to argue they didn’t infringe the DDI patents. Based on last night’s ruling, it would appear this generic noninfringement strategy on the DDI patents is foreclosed. Further, with JAZZs DDI patents withstanding the invalidity challenge in multiple inter partes reviews (IPR) relating to the obviousness of those patents, those patents now appear much stronger and likely to withstand two central arguments they’d anticipate when the patent dispute moves to the district court in May 2017 (lead case). Based on the above considerations, firm believes the generic companies will be more likely to accept JAZZ’s likely settlement offer to launch in late 2025E since the risk of getting blocked until 2033E looks increasingly probable.
January 17, 2017: The U.S. Food and Drug Administration (FDA) has approved Jazz’s Xyrem, the first generic version of Xyrem (sodium oxybate) Oral Solution, to treat cataplexy and excessive daytime sleepiness in patients with narcolepsy, which is a potentially debilitating disease. Cataplexy is a primary symptom of narcolepsy where patients suddenly lose muscle tone, including voluntary muscle control, while awake. Muscle weakness or paralysis associated with cataplexy may cause a person to collapse. Approximately 70 percent of people with narcolepsy have cataplexy. Sodium oxybate is the only medication approved to treat cataplexy in patients with narcolepsy.
The use of Xyrem has been associated with serious side effects including seizures, trouble breathing, changes in alertness, coma, and death. Additionally, the active ingredient in Xyrem (and in the newly approved generic) is sodium oxybate. Sodium oxybate is the sodium salt of gamma-hydroxybutyrate (GHB). GHB has not been approved for any medical use and has the potential for abuse, such as in cases of sexual assault.
Because of the potential risks associated with Xyrem, it is subject to strict safety controls on prescribing and dispensing under a program called a Risk Evaluation and Mitigation Strategy (REMS). FDAs approval of generic sodium oxybate is subject to a REMS with strict safety controls that are comparable to those currently required for Xyrem.
Specifically, under both the Xyrem REMS and the generic sodium oxybate REMS, sodium oxybate can be prescribed only by a certified prescriber, and dispensed only to an enrolled patient by a certified pharmacy. Only a certified pharmacy that ships directly to patients can dispense sodium oxybate. Sodium oxybate will not be available in retail pharmacies.
In approving this generic version of Xyrem, the FDA is maintaining strict safety requirements for sodium oxybate, while providing patients with access to a generic medication option for narcolepsy. Source: http://www.fda.gov/Drugs/DrugSafety/ucm537281.htm
