 Interferon beta-1a - Wikipedia, the free encyclopedia
Interferon beta-1a is a drug in the interferon family used to treat multiple sclerosis.
Rebif ( interferon beta-1a) is a disease -modifying drug used to treat relapsing forms of multiple sclerosis (MS) and is similar to the interferon beta protein produced by the human body.
Interferons have been shown to have about a 30-35% reduction in the rate of MS relapses, and to slow the progression of disability in MS patients.

 Clinical Trial: Safety Study of Interferon Beta 1a to for Acute Stroke
Interferon beta 1a is approved for use in patients with multiple sclerosis to prevent further brain injury caused by inflammation; the drug may also help prevent further brain injury in patients with acute stroke.
The dose of interferon beta 1a is increased in successive groups of patients, so that the first group to enter the study receives 11 micrograms (mcg) of the drug, the next receives 22 mcg, then 44 mcg, 66 mcg, and 88 mcg.
This study will examine the safety of the drug interferon beta 1a in patients with acute ischemic stroke to determine the highest dose patients can tolerate without serious side effects and to determine the best way to give the medication.

 News - Study Confirms Benefits of High-Dose, High-Frequency Beta Interferon Regimen in Treatment for Multiple Sclerosis
Clinical activity significantly worsened during the year on interferon beta-1a and although it improved during the year after returning to high-dose, high-frequency beta interferon, the MRI activity persisted in some patients, failing to return to the total absence of disease activity demonstrated after three years of chronic interferon beta-1b treatment.
In conclusion, the reduction in beta interferon dose and frequency may be associated with increased signs of clinical and MRI disease activity.
The study was prompted by the hypothesis that once MS is controlled for several years using a high-dose, high-frequency beta interferon regimen, it might be possible to maintain the beneficial immunological and clinical effects using lower doses or less frequent applications of beta interferon.

 MedicalPost.com: AAN: Plan can I.D. non-response to interferon
Based on the first year clinical data, 21 (12%) patients in the 22 mcg interferon beta-1a group and 19 (10%) patients in the 44 mcg interferon beta-1a group were considered to be at high concern for a sub-optimal response.
Overall, 180 patients in the 22 mcg interferon beta-1a and 182 patients in the 44 mcg interferon beta-1a groups were included in the analysis.
In the following years, three patients on 22 mcg interferon beta-1a and three patients on 44 mcg interferon beta-1a who were assigned high concern status did not have a relapse.

 Multiple sclerosis
Interferon beta 1a (Avonex, Rebif), interferon beta 1b (Betaseron) and glatiramer acetate (Copaxone) are currently used in the management of multiple sclerosis and are believed to alter the course of disease, reduce future disability and improve quality of life.
The National Multiple Sclerosis Society recommends treatment with one of the licensed “disease modifying” drugs as soon as possible after the diagnosis of a relapsing form (the most common kind) of multiple sclerosis.
These drugs help to lessen the frequency and severity of multiple sclerosis attacks, reduce the accumulation of lesions (areas of damage) in the brain, and slow the progression of disability.

Pregnancy Registries for the Interferon Beta Products Prescribed for Women with MS The FDA issued guidelines requiring the manufacturers of Avonex, Betaseron, and Rebif to develop pregnancy registries to monitor women who have taken one of these drugs within a week of becoming pregnant or while they were pregnant.
It is made up of exactly the same amino acids (major components of proteins) as the interferon beta found in the human body.
However, some patients treated with interferons, including Rebif, have become seriously depressed, and depression and suicidal thoughts are known to occur with some frequency in MS.

 High-dose interferon beta-1b for multiple sclerosis patients
There are three interferon beta therapies known to be effective in reducing MS symptoms: interferon beta-1a 30 mcg administered intramuscularly once a week; interferon beta-1a 22 mcg or 44 mcg given subcutaneously three times a week; and interferon beta-1b 250 mcg administered subcutaneously on alternate days.
Over 2 years, 51% of individuals administered interferon beta-1b remained relapse-free compared with 36% given interferon beta-1a; 55% compared with 26%, respectively, remained free from new proton density/T2 brain lesions at the MRI assessment.
In a 2-year prospective study, 188 patients with relapsing-remitting MS were randomised to receive either interferon beta-1b or interferon beta-1a.
