This is a 2-week double-blind, placebo-controlled, parallel group study comparing the anti-inflammatory effects of low, medium, and high dose mometasone furoate/formoterol fumarate MDI formulation and medium dose mometasone furoate (MF) DPI and MDI formulations in adults and adolescents with persistent allergic asthma. An open-label run in period is to be followed by a double-blind treatment period.~A total of 90 subjects (15 per treatment) will be enrolled to ensure 12 subjects per treatment at the Day 14 evaluation, accounting for a 20% drop-out rate. A sample size of 12 subjects per treatment is required to detect a treatment difference of 28% in percent change of eNO at Day 14, assuming a pooled standard deviation of 20% with a power of 90%. These estimates are based on examination of eNO levels in asthmatic vs healthy subjects in an article written by S.A. Kharitonov et. al, 2003.~Subjects will be randomized to one of six treatment groups (MF/F MDI 100/10 mcg BID, MF/F MDI 200/10 mcg BID, MF/F MDI 400/10 mcg BID, MF DPI 200 mcg BID, MF MDI 200 mcg BID, or Placebo MDI BID) according to an Schering-Plough Research Institute (SPRI) computer-generated randomization schedule. Randomization will be performed in appropriately sized blocks using random numbers generated by statistical analysis software (SAS).
This is a 2-week double-blind, placebo-controlled, parallel group study comparing the anti-inflammatory effects of low, medium, and high dose mometasone furoate/formoterol fumarate (MF/F) metered dose inhaler (MDI) formulation and medium dose mometasone furoate (MF) dry powder inhaler (DPI) and MDI formulations in adults and adolescents with persistent allergic asthma.
