Dataset from Clinical Assessment of Fluticasone Propionate/ Salmeterol Xinafoate HFA MDI in 6-month to 4-year-old Japanese Patients With Bronchial Asthma

This study is a multicenter, stratified, randomized, active control, double-blinded, parallel-group comparative study with an open-label extension period. The study is designed to evaluate the efficacy and safety of FP/ SLM HFA MDI 50/25 microgram (mcg) one or two inhalation twice daily (BID) for 8 weeks in comparison with FP HFA MDI 50 mcg one or two inhalation BID, in 6-month to 4-year-old Japanese patients with bronchial asthma. The study is also designed to evaluate the safety of long-term treatment of FP/ SLM HFA MDI 50/25 mcg one or two BID for 16 weeks. The subjects meeting the eligibility criteria will enter the run-in period of 2 weeks and receive FP 50 mcg 1 or 2 inhalation bid (FP 100 or 200 mcg/day), before randomization. The subjects under 2 years of age at Visit 1 will receive only 1 inhalation bid during the run-in period. The subjects who meet the eligibility criteria for randomization will be stratified according to their age (<2 or >=2 year-old) at Visit 1 and randomized to one of the two treatment groups. The total duration of participation in the study will be 10 weeks for a comparison period completion and 27 weeks for a completion.
