Background: Coronavirus disease 2019 (Covid-19) disproportionately results in hospitalization or death in older patients and those with underlying conditions. Sotrovimab is a pan-sarbecovirus monoclonal antibody that was designed to prevent progression of Covid-19 in high-risk patients early in the course of disease.

Methods: In this ongoing, multicenter, double-blind, phase 3 trial, we randomly assigned, in a 1:1 ratio, nonhospitalized patients with symptomatic Covid-19 (≤5 days after the onset of symptoms) and at least one risk factor for disease progression to receive a single infusion of sotrovimab at a dose of 500 mg or placebo.

Background: Ocrelizumab is an infusible humanized monoclonal antibody that selectively depletes CD20 B cells. Infusion-related reactions (IRRs) were summarized from the OPERA I, OPERA II, and ORATORIO trials for relapsing and primary progressive multiple sclerosis (MS).

Methods: OPERA I and OPERA II were identical, randomized, double-blind, active-controlled trials that enrolled patients with relapsing MS (RMS).

Background & Aims: The comparative efficacy and safety of infliximab and azathioprine therapy alone or in combination for ulcerative colitis (UC) have not been evaluated previously.

Methods: This randomized, double-blind trial evaluated the efficacy and safety of 16 weeks of treatment with infliximab monotherapy, azathioprine monotherapy, or the 2 drugs combined in tumor necrosis factor-a antagonist-naive adults with moderate to severe UC. Patients were assigned randomly to receive intravenous infusions of infliximab 5 mg/kg at weeks 0, 2, 6, and 14 plus daily oral placebo capsules; oral azathioprine 2.

Background & Aims: Pegylated interferon (PEG-IFN) alfa-2b plus ribavirin (RBV) is the standard of care for adults with chronic hepatitis C but was not approved for the treatment of children at the time of this study. The aim of this study was to evaluate the efficacy and safety of PEG-IFN alfa-2b plus RBV in children.

Methods: Children and adolescents ages 3-17 years were treated with PEG-IFN alfa-2b (60microg/m(2)/week) plus RBV (15mg/kg/day).
