Ozanimod Induction and Maintenance Treatment for Ulcerative Colitis.

Background: Ozanimod (RPC1063) is an oral agonist of the sphingosine-1-phosphate receptor subtypes 1 and 5 that induces peripheral lymphocyte sequestration, potentially decreasing the number of activated lymphocytes circulating to the gastrointestinal tract.

Methods: We conducted a double-blind, placebo-controlled phase 2 trial of ozanimod in 197 adults with moderate-to-severe ulcerative colitis. Patients were randomly assigned, in a 1:1:1 ratio, to receive ozanimod at a dose of 0.

Lesinurad in combination with allopurinol: results of a phase 2, randomised, double-blind study in patients with gout with an inadequate response to allopurinol.

Objectives: To assess the efficacy and tolerability of lesinurad, an oral selective uric acid reabsorption inhibitor, in combination with allopurinol versus allopurinol alone in patients with gout and an inadequate response to allopurinol.

Methods: Patients (N=227) with an inadequate response to allopurinol, defined as serum urate (sUA) ≥6 mg/dL on ≥2 occasions ≥2 weeks apart despite ≥6 weeks of allopurinol, were randomised 2:1 to 4 weeks of double-blind treatment with lesinurad (200, 400 or 600 mg/day) or matching placebo in combination with their prestudy allopurinol dose (200-600 mg/day). Colchicine prophylaxis for gout flares was required.

Safety and efficacy of additional courses of rituximab in patients with active rheumatoid arthritis: an open-label extension analysis.

Objective: To determine the safety and efficacy of additional courses of rituximab in patients with rheumatoid arthritis (RA).

Methods: An open-label extension analysis of RA patients previously treated with rituximab was conducted. Patients who had participated in any of 3 double-blind trials were eligible for additional courses (2 infusions of 1,000 mg given 2 weeks apart) if they exhibited a swollen joint count and tender joint count of > or =8 with > or =16 weeks elapsing after the previous course.

Rituximab for rheumatoid arthritis refractory to anti-tumor necrosis factor therapy: Results of a multicenter, randomized, double-blind, placebo-controlled, phase III trial evaluating primary efficacy and safety at twenty-four weeks.

Objective: To determine the efficacy and safety of treatment with rituximab plus methotrexate (MTX) in patients with active rheumatoid arthritis (RA) who had an inadequate response to anti-tumor necrosis factor (anti-TNF) therapies and to explore the pharmacokinetics and pharmacodynamics of rituximab in this population.

Methods: We evaluated primary efficacy and safety at 24 weeks in patients enrolled in the Randomized Evaluation of Long-Term Efficacy of Rituximab in RA (REFLEX) Trial, a 2-year, multicenter, randomized, double-blind, placebo-controlled, phase III study of rituximab therapy. Patients with active RA and an inadequate response to 1 or more anti-TNF agents were randomized to receive intravenous rituximab (1 course, consisting of 2 infusions of 1,000 mg each) or placebo, both with background MTX.
