Long-term safety of mepolizumab for the treatment of hypereosinophilic syndromes.

Background: Hypereosinophilic syndromes (HESs) are chronic disorders that require long-term therapy to suppress eosinophilia and clinical manifestations. Corticosteroids are usually effective, yet many patients become corticosteroid refractory or develop corticosteroid toxicity. Mepolizumab, a humanized monoclonal anti-IL-5 antibody, showed corticosteroid-sparing effects in a double-blind, placebo-controlled study of FIP1L1/PDGFRA-negative, corticosteroid-responsive subjects with HESs.

Treatment of patients with the hypereosinophilic syndrome with mepolizumab.

Background: The hypereosinophilic syndrome is a group of diseases characterized by persistent blood eosinophilia, defined as more than 1500 cells per microliter with end-organ involvement and no recognized secondary cause. Although most patients have a response to corticosteroids, side effects are common and can lead to considerable morbidity.

Methods: We conducted an international, randomized, double-blind, placebo-controlled trial evaluating the safety and efficacy of an anti-interleukin-5 monoclonal antibody, mepolizumab, in patients with the hypereosinophilic syndrome.

Placebo response in two long-term randomized psoriasis studies that were negative for rosiglitazone.

Background: Previous research has suggested that the thiazolidinedione rosiglitazone may possess anti-psoriatic activity.

Objective: To compare the efficacy and safety of rosiglitazone with that of placebo in the treatment of chronic plaque psoriasis.

Methods: Two large-scale, randomized, double-blind, multicenter studies (study A, n = 1563; study B, n = 1032) were conducted over 52 weeks (plus optional 44 weeks safety extension) in an outpatient setting.

An open label study to establish dosing recommendations for nabumetone in juvenile rheumatoid arthritis.

Objective: Once-a-day dosing with nabumetone has been shown to be effective in adults with rheumatoid arthritis. We establish dosing recommendations for nabumetone in children and adolescents with juvenile rheumatoid arthritis (JRA).

Methods: An open label, multicenter study was conducted in children with JRA aged 2-16 years, weighing > 14 kg, and requiring nonsteroidal antiinflammatory drugs (NSAID) for control of symptoms.

Effects of nabumetone, celecoxib, and ibuprofen on blood pressure control in hypertensive patients on angiotensin converting enzyme inhibitors.

Nonsteroidal anti-inflammatory drugs interfere with certain antihypertensive therapies. In a double-blind study, 385 hypertensive patients stabilized on an angiotensin converting enzyme inhibitor were treated with nabumetone, celecoxib, ibuprofen, or placebo for 4 weeks. Ibuprofen caused significantly greater increases in systolic (P < .
