Randomized Controlled Trial Multicenter StudyMK-0633, a potent 5-lipoxygenase inhibitor, in chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is associated with neutrophil-mediated inflammation, a potential target for treatment in COPD. We evaluated MK-0633, a 5-lipoxygenase inhibitor in patients with COPD. This was a 12 week, randomized, double-blind, multicenter study comparing MK-0633 100 mg and placebo in patients 40-75 years of age (N = 266) with COPD, post-β-agonist forced expiratory volume in 1 s (FEV(1)) 25%-75% predicted, and an FEV(1)/forced vital capacity ratio (FVC) ≤ 70%. ⋯ MK-0633 was well-tolerated and comparable to placebo. The 5-LO inhibitor MK-0633 was not significantly more effective than placebo in improving FEV(1) from baseline in patients with COPD, although more patients reported feeling improved with MK-0633. Clinicaltrials.gov identifier: NCT00418613.
