The green, capsule-shaped pill with the imprint BG-12 240 mg has been identified as (Dimethyl fumarate) Tecfidera 240 mg supplied by Biogen Idec Inc.. While the green, white capsule-shaped pill with the imprint BG-12 120 has been identified as Tecfidera 120 mg also supplied by Biogen Idec Inc.. BG 12 pill is a disease modifying treatment (DMT) recommended for the treatment of ‘active’ relapsing multiple sclerosis. This is defined in guidelines as two or more relapses in the last two years.
In one trial, on average, people with multiple sclerosis saw a 53% drop in the number of relapses they had. In another trial, on average, people with MS saw a 38% drop in their disability getting worse. These trial results were compared to people wth MS taking placebos.
Rather than counting a specific number of relapses, increasing numbers of MS specialists define ‘active’ multiple sclerosis as one recent relapse and/or signs on MRI scans that MS is active. These signs include new lesions, areas of damage, in the brain.
This disease modifying treatment is recommended for those with ‘active’ relapsing multiple sclerosis. BG 12 pill won’t work if you don’t get relapses, so you won’t be offered it if you have primary or secondary progressive MS.
How does BG 12 pills work to treat multiple sclerosis (MS)?
Originally a drug for the treatment of psoriosis, a trial in 2012 found that it could be an effective treatment for multiple sclerosis. We don’t know exactly how it works, but it dampens down inflammation. This may be helpful in reducing the inflammation that causes damage in the brain and spinal cord of people with MS. In 2014, the National Institute for Health and Care Excellence (NICE) gave the go ahead for the drug to be used on the NHS.
How well does BG 12 pill work?
MS drugs can be put into three groups based on how well they control it. The effectiveness of BG 12 pill is classed as ‘good’. This puts it between DMTs classed as ‘high’ effectiveness and those classed as ‘moderate’. This is based on how much it reduces relapses and slows down how fast people’s disability gets worse.
Relapses dropped by: 53%
This means that in one trial, on average, people saw a 53% drop in the number of relapses they had. This was compared to people who took a placebo, a dummy treatment with no drug in it.
Disability getting worse was slowed down by: 38%
This means that in one trial, on average, people saw a 38% drop in the risk of their disability getting worse. This was compared to people who took a placebo.
