Effect of ocrelizumab on vaccine responses in patients with multiple sclerosis: The VELOCE study.

Objective: The phase IIIb A Study to Evaluate the Effects of Ocrelizumab on Immune Responses in Participants With Relapsing Forms of Multiple Sclerosis (VELOCE) study (NCT02545868) assessed responses to selected vaccines in ocrelizumab (OCR)-treated patients with relapsing multiple sclerosis.

Methods: Patients were randomized 2:1 into the OCR group (n = 68; OCR 600 mg) or control group (n = 34; interferon beta or no disease-modifying therapy). All received tetanus toxoid (TT)-containing vaccine, Pneumovax (23-valent pneumococcal polysaccharide vaccine [23-PPV]), and keyhole limpet hemocyanin (KLH).

Treatment retention on fingolimod compared with injectable multiple sclerosis therapies in African-American patients: A subgroup analysis of a randomized phase 4 study.

Background: Suboptimal persistence with injectable disease-modifying therapies (iDMTs; interferon beta-1a/b, glatiramer acetate) is common in patients with relapsing forms of multiple sclerosis (MS), reducing the effectiveness of these agents. Adherence to, and persistence with, an effective therapy is important for patient populations at increased risk of rapid disease progression. African-American individuals with multiple sclerosis may experience a more aggressive disease course than Caucasian patients, with a greater risk of developing ambulatory difficulties and other disabilities, and may also have a diminished response to some disease-modifying therapies compared with patients of other ethnicities.

A randomized, double-blind, placebo-controlled trial of the efficacy and tolerability of a 4-mg dose of subcutaneous sumatriptan for the treatment of acute migraine attacks in adults.

Objective: The aim of this study was to evaluate the efficacy and tolerability of a single 4-mg dose of sumatriptan SC for the acute treatment of adult patients experiencing a migraine attack with moderate to severe pain.

Methods: In this randomized, double-blind, placebo-controlled study, subjects included men and women aged 18 to 60 years who had migraine with or without aura, as defined by the 1988 International Headache Society criteria. Subjects received either sumatriptan 4 mg SC or placebo SC for a migraine attack with headache pain of moderate to severe intensity.

Enhanced benefit of increasing interferon beta-1a dose and frequency in relapsing multiple sclerosis: the EVIDENCE Study.

Background: The EVIDENCE (Evidence of Interferon Dose-Response: European North American Comparative Efficacy) Study demonstrated that patients with multiple sclerosis (MS) who initiate interferon beta-1a therapy with 44 microg 3 times weekly (TIW) were less likely to have a relapse or activity on magnetic resonance imaging (MRI) compared with those who initiate therapy at a dosage of 30 microg 1 time weekly (QW).

Objective: To determine the effect of changing the dosage from 30 microg QW to 44 microg TIW in this extension of the EVIDENCE Study.

Design/patients: Patients with relapsing MS originally randomized to interferon beta-1a, 30 microg QW, during the comparative phase of the study changed to 44 microg TIW, whereas patients originally randomized to 44 microg TIW continued that regimen.
