About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Parallel Group Study to Investigate the Safety and Efficacy of Arbaclofen Extended-Release Tablets for the Treatment of Spasticity in Patients With Multiple Sclerosis

Multiple Sclerosis (MS) is an acquired inflammatory demyelinating disease of the central nervous system (CNS) that is regarded as the foremost cause of non-traumatic neurologic disability in adults in North America. Spasticity is a common complication in MS and occurs in up to 84% of patients. The main sign of spasticity is resistance to passive limb movement characterized by increased resistance to stretching, clonus, and exaggerated deep reflexes. Osmotica Pharmaceutical is currently developing arbaclofen extended-release tablets (AERT) for the treatment of spasticity in patients with MS.

Read the detailed description

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the safety and efficacy of oral AERT in MS patients with spasticity. Two doses of AERT, 40 mg and 80 mg, will be compared with placebo. The treatment groups will be randomized in a 1:1:1 ratio. Eligible patients will undergo a washout period for withdrawal of all medications used for anti-spasticity and/or muscle relaxation prior to randomization. A baseline clinical evaluation will be performed (Visit 2) to confirm eligibility for study randomization, and subjects will be randomly assigned to 1 of 3 treatment arms. Subjects will remain on maintenance treatment for approximately 3 months.

What is being measured

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

  1. Change From Baseline in Total Numeric-transformed Modified Ashworth Scale Score of the Most Affected Limb (TNmAS-MAL)

    Total Numeric-Transformed Modified Ashworth Scale (TNmAS) is a 6-point scale to measure abnormality in tone or the resistance to passive movements. Higher score is worse outcome.

    For each joint, the minimum score is 0; maximum score is 5. The values for each of the 3 main joints are summed for the limb score. The limb with the highest score is the most affected limb (MAL). The highest possible score for a limb is 15. Limb range: 0 to 15.

    To arrive at total limbs (TL) score the values for all 4 limbs are summed; maximum total limb score is 60. TL range: 0 to 60.

    Measured: 84 days

  2. Clinical Global Impression of Change (CGIC)

    The Clinical Global Impression of Change (CGIC) was developed to provide a brief, stand-alone assessment of the clinician's view of the subject's global functioning prior to and after initiating a study medication. The scale ranges from -3 to +3 judging whether the change is significantly worse (-3) to significantly improved (+3). Higher score is better outcome. The CGIC scale will be used to measure the overall change in the subject's condition since starting the study. There is no baseline value because the score is a measure of how the patient changed from baseline (treatment initiation).

    Measured: 84 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Arbaclofen in people with Multiple Sclerosis and Spasticity, Muscle, run by RVL Pharmaceuticals, Inc. at 30 sites in 7 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 7 inclusion and 6 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: finished, as of the sponsor's last update on 15 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 sites in Poland, Bulgaria, Belarus, Croatia, Serbia and 2 more countries. 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 15 Jul 2022). 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 From Baseline in Total Numeric-transformed Modified Ashworth Scale Score of the Most Affected Limb (TNmAS-MAL) (time frame: 84 days). The study lists 2 primary outcomes in all. 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 15 Jul 2022.
