About this study

Official title: A Double-blind, Randomized, Placebo-controlled, Parallel-group Trial of the Efficacy and Safety of Nabiximols Oromucosal Spray as Add-on Therapy in Patients With Spasticity Due to Multiple Sclerosis

This trial is being conducted to demonstrate the efficacy of nabiximols, compared with placebo, when added to standard of care, in the treatment of muscle spasms associated with multiple sclerosis (MS).

Read the detailed description

This multicenter, double-blind, placebo-controlled trial includes a 28-day Baseline period, a 12-week treatment period (comprising a 2-week titration phase and a 10-week maintenance phase), and 2-week follow-up period.

Eligible participants will enter the 28-day baseline period. During baseline, participants will maintain their optimized oral MS antispasticity medication regimen and record spasm count using an electronic daily diary. At screening (Day 1), eligible participants will be randomized to either nabiximols or placebo in a 1:1 ratio.

Participants will be advised to titrate the investigational medicinal product (IMP), beginning with 1 spray/day, to an optimized dose or to a maximum of 12 sprays/day over the first 14 days of treatment. Participants may leave a gap between sprays of approximately 15 minutes. Participants should continue at the same dose level achieved at the end of the titration phase ±1 spray divided into a morning dose and an evening dose for the remainder of the treatment period.

Daily spasm count, the participant's symptom experiences, clinician's assessment of spasticity, functional outcomes, health-related quality of life, changes in mood, safety, tolerability, and pharmacokinetics will be evaluated during the treatment period.

Participants who complete the trial will participate for a total of approximately 18 weeks (127 days), including the 28-day baseline period. Participants will have a maximum duration of 85 (±7) days on IMP treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NabiximolsDrug

    Also called GW-1000-02, Sativex

    Nabiximols is a complex botanical medicine formulated from extracts of the cannabis plant that contains the principal cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) and also contains minor constituents, including other cannabinoid and non-cannabinoid plant components, such as terpenes, sterols, and triglycerides.Nabiximols will be self-administered by participants as an oromucosal spray in the morning and evening, up to a maximum of 12 sprays per day for 12 weeks.

  • PlaceboDrug

    Placebo to match nabiximols will be presented as an oromucosal spray containing the excipients ethanol and propylene glycol (50% v/v) with colorings and flavored with peppermint oil (0.05% v/v). Each spray will deliver 100 microliters (μL) containing no active ingredients. Placebo will be self-administered by participants as an oromucosal spray in the morning and evening, up to a maximum of 12 sprays per day for 12 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Average Daily Spasm Count From Baseline to Week 12 By 4-Week Period During the 12-Week Randomized Period

    The change in the average daily spasm count was assessed compared to the baseline period.

    Measured: Baseline to Week 12

Secondary outcomes (14)
  1. Change in Multiple Sclerosis Spasticity Scale (MSSS-88) Total Score

    The MSSS-88 is a self-reported measure of the impact of spasticity (muscle stiffness and spasms) in MS. This 88-item scale captures the patient experience and impact of spasticity, including muscle stiffness, pain and discomfort, muscle spasms, effect on daily activities, ability to walk, body movement, patient feelings, and social functioning. Responses to individual questions can range from "1 - not at all bothered" to "4 - extremely bothered", ranging from 88 to 352 total score. Scores are summed and higher scores indicate poor clinical outcome. Least square means are being reported, with greater negative values indicating better outcome.

    Measured: Week 8 and Week 12

  2. Number of Patients Reporting Any Treatment-emergent Adverse Events

    A TEAE is an adverse event that started, or worsened in severity or seriousness, following the first dose of the investigational medicinal product.

    Measured: From date of first dose of IMP up to 30 days after last dose, up to approximately 16 weeks

  3. Change From Baseline in Clinical Laboratory Test Values

    Measured: Baseline up to Week 12

  4. Change From Baseline in Erythrocytes

    Measured: Baseline up to Week 12

  5. Change From Baseline in Hemoglobin

    Measured: Baseline up to Week 12

  6. Change From Baseline in Hematocrit Ratio

    The hematocrit ratio measures the volume of red blood cells compared to the total blood volume.

    Measured: Baseline up to Week 12

  7. Change From Baseline in Erythrocyte Mean Corpuscular Hemoglobin

    Measured: Baseline up to Week 12

  8. Change From Baseline in Blood Pressure

    Measured: Baseline up to Week 12

  9. Change From Baseline in Heart Rate

    Measured: Baseline up to Week 12

  10. Change From Baseline in Electrocardiogram Parameters

    Measured: Baseline up to Week 12

  11. Change From Baseline in Electrocardiogram Pulse Rate

    Measured: Baseline up to Week 12

  12. Change From Baseline in Weight

    Measured: Baseline up to Week 12

  13. Change in Body Mass Index

    Measured: Baseline up to Week 12

  14. Number of Patients With Suicidal Ideation or Behavior Based on Columbia-Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS is a short questionnaire that is used to assess suicidal ideation (5 questions) and behavior (5 questions) since last patient visit. The questionnaire is completed by participants answering yes or no to each question.

    Measured: Screening up to Week 12

A Phase 3 study testing Nabiximols in people with Multiple Sclerosis (MS), run by Jazz Pharmaceuticals at 37 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 8 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in United States, Poland, Czechia, Romania, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Average Daily Spasm Count From Baseline to Week 12 By 4-Week Period During the 12-Week Randomized Period (time frame: Baseline to Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2024.
