MS Trial Alert: Investigators Recruiting People with MS and Spasticity for a Study of Extended-Release Baclofen

December 18, 2014

Summary: Investigators nationwide are recruiting 214 people for a study to determine the effectiveness of extended-release baclofen capsules in relieving spasticity and symptoms related to MS. The study is sponsored by Sun Pharma Advanced Research Company Limited.

Rationale: Spasticity refers to feelings of stiffness and a wide range of involuntary muscle spasms (sustained muscle contractions or sudden movements). It is one of the more common and troublesome symptoms of MS. Baclofen acts on the central nervous system to relieve spasms, cramping, and tightness of muscles caused by spasticity. This study is evaluating an extended-release form of baclofen. Extended release – in which a drug is released over time – may allow for it to be taken less often.

Eligibility and Details: Participants should be at least 18 years old, have any form of MS and a known history of spasticity. Participants should be taking immediate-release baclofen (30 to 60 mg) at the same dose and the same schedule for the last 30 days. Further details on enrollment criteria are available from the contact below.

Participants will receive baclofen immediate release capsules daily for one week, and then extended-release capsules daily for up to 16 weeks (doses will increase from 10 to 60 mg). Then participants will be randomly chosen to receive either the investigational drug or an inactive placebo for up to an additional 4 weeks. The dosage will gradually decrease during these 4 weeks.

The primary outcomes being measured are how many participants are able to complete the study, and safety.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are leading to better understanding and moving us closer to a world free of MS. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease. MS affects more than 2.3 million people worldwide.
