The FDA has approved a pegylated form of interferon beta-1a (Plegridy – Biogen) for biweekly treatment of patients with relapsing multiple sclerosis (MS).

Natalizumab, a recombinant humanized monoclonal antibody, has received accelerated approval from the FDA for intravenous treatment of relapsing forms of multiple sclerosis (MS). The beta interferons and glatiramer acetate are widely used for treatment of MS; they generally reduce the number of relapses by about 30% compared to placebo, and have been shown to be safe and effective for periods ranging from 4 to 10 years.

The FDA has approved ocrelizumab (Ocrevus – Genentech), a humanized anti-CD20 monoclonal antibody, for treatment of adults with primary progressive or relapsing multiple sclerosis (MS). It is the first anti-CD20 monoclonal antibody to be approved for treatment of MS and the first disease-modifying drug to be approved in the US for primary progressive MS.

The FDA has approved daclizumab (Zinbryta – Biogen/Abbvie), an interleukin-2 (IL-2) receptor blocking monoclonal antibody, for treatment of adults with relapsing forms of multiple sclerosis (MS). It is the first subcutaneously injected monoclonal antibody to be approved for treatment of MS.

Most patients with multiple sclerosis (MS) present with the relapsing-remitting form of the disease. Pharmacologic treatment usually includes a disease-modifying drug, corticosteroids for acute exacerbations, and other drugs for managing symptoms such as fatigue, depression, and pain. Early use of disease-modifying therapy has improved clinical outcomes.
