| | Nabiximols oromucosal spray continues to be evaluated in ongoing clinical trials in multiple sclerosis spasticity DUBLIN, June 28, 2022 /PRNewswire/ -- Jazz Pharmaceuticals, Inc. (Nasdaq: JAZZ) today announced top-line results from the Phase 3 RELEASE MSS1 trial (NCT04657666) evaluating nabiximols oromucosal spray (JZP378, or Sativex ®, ex-U.S.) on clinical measures of spasticity in individuals with multiple sclerosis (MS). The RELEASE MSS1 trial did not meet the primary endpoint of change in Lower Limb Muscle Tone-6 (LLMT-6) between baseline and Day 21, as measured by the Modified Ashworth Scale (MAS). Nabiximols oromucosal spray is a complex botanical mixture formulated from extracts of the cannabis sativa plant and contains the cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), as well as other cannabinoid and non-cannabinoid components. Nabiximols oromucosal spray (known as Sativex ex-U.S. and first approved in the U.K. in 2010) has been approved in 29 countries for the treatment of adult patients with moderate to severe spasticity due to MS who have not responded adequately to other anti-spasticity medication based on previously completed clinical trials. “We remain committed to the nabiximols program and are actively assessing the RELEASE MSS1 trial results, which will be presented at a future medical meeting. We look forward to additional data from two other ongoing trials that have the potential to support a U.S. FDA New Drug Application submission,” said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development at Jazz Pharmaceuticals. “I would like to extend a heartfelt thank you to all those who supported and made this study possible, including the patients who were enrolled, their families, our investigators, staff, and all of the dedicated Jazz employees.” RELEASE MSS1 was the first, and smallest, of the three clinical trials in the current program, and it evaluated the safety and efficacy of nabiximols oromucosal spray in 68 patients with MS spasticity. Data from these trials will continue to be evaluated as it becomes available, to support the overall registrational program in the U.S. Two additional, ongoing Phase 3 trials to complement and inform a comprehensive development plan include: - RELEASE MSS3: A Phase 3 multicenter, double-blind, placebo-controlled trial evaluating the efficacy of nabiximols oromucosal spray, compared to placebo, when added to standard of care, for the improvement of muscle spasms associated with MS over a 12-week treatment period. Estimated enrollment is 446 participants.
- RELEASE MSS5: A Phase 3 multicenter, randomized, double-blind, placebo-controlled, 2-treatment, 2-period, crossover trial evaluating the effect of multiple doses of nabiximols oromucosal spray compared to placebo on a clinical measure of velocity-dependent muscle tone in the lower limbs (Lower Limb Muscle Tone-6 [LLMT-6]) in participants with MS over a 3-week treatment period. Estimated enrollment is 190 participants.
The safety profile in RELEASE MSS1 was consistent with previously reported adverse events, with no new safety signals attributable to nabiximols oromucosal spray observed in this population. Data from the RELEASE MSS1 trial will be submitted for presentation at a future medical meeting. About the RELEASE MSS1 Trial
RELEASE MSS1 (NCT04657666) is a randomized, double-blind, placebo-controlled, two-way crossover trial that enrolled 68 adults with multiple sclerosis (MS) to evaluate the effect of nabiximols oromucosal spray on clinical measures of spasticity over a 3-week treatment period. After the trial initiated, the trial protocol was amended to provide flexibility on enrollment size. Ultimately, the initial intended number of patients was enrolled, and 68 patients were randomized. Participants entering the trial were over 18 years of age with a confirmed diagnosis of any disease subtype of MS for at least 12 months prior to first visit, were expected to remain stable for the duration of the trial and experienced spasticity not relieved by their current anti-spasticity medications. Participants were randomized in a 1:1 ratio to one of two sequences comprised of treatment with nabiximols oromucosal spray and placebo. In the first period of the crossover trial, participants were titrated to a maintenance dose of nabiximols oromucosal spray or placebo in a blinded fashion; in the second period of the trial, participants then initiated therapy with the alternate study drug in a blinded fashion. The primary endpoint in RELEASE MSS1 was a measure of change from baseline in Lower Limb Muscle Tone-6 (LLMT-6) as defined by the Modified Ashworth Scale (MAS) at the end of each period, compared to placebo. The secondary endpoints were change in Lower Limb Muscle Tone-4 (LLMT-4) as defined by the MAS, safety, and tolerability of nabiximols oromucosal spray, in individuals with MS spasticity. About Nabiximols Oromucosal Spray
Nabiximols oromucosal spray is a complex botanical mixture formulated from extracts of the cannabis sativa plant. Nabiximols oromucosal spray contains the cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), as well as other cannabinoid and non-cannabinoid components. Currently, there are no U.S. Food and Drug Administration (FDA) approved cannabis-derived medications that contain THC, and Epidiolex® is the only FDA approved cannabis-derived therapy. Nabiximols oromucosal spray is indicated outside the U.S. as a treatment for symptom improvement in adult patients with moderate to severe spasticity due to multiple sclerosis (MS) who have not responded adequately to other anti-spasticity medications and who demonstrate clinically significant improvement in spasticity related symptoms during an initial trial of therapy. Nabiximols oromucosal spray is investigational and currently not approved for any indication in the U.S. About Multiple Sclerosis Spasticity
Multiple sclerosis (MS) spasticity is one of the most common motor syptoms associated with MS.1 MS spasticity often manifests as involuntary muscle stiffness and/or spasms, occurring in up to 84 percent of individuals with MS, and approximately one-third of individuals with MS still live with uncontrolled spasticity symptoms.2-4 However, MS spasticty can also lead to pain, sexual dysfunction, dysarthria, fatigue, depression and anxiety, mobility impairment, bladder and bowel dysfunction, and sleep disturbances.2,5-7 Less than half of individuals with MS receiving treatment for spasticity are satisfied with the current treatment regimens2 and 41 percent of physicians are dissatisfied with current treatment regimens.8 About Jazz Pharmaceuticals plc
