This will be a multi-center, randomized, placebo controlled parallel-group study to Replicate Efficacy of Nebulized Fluticasone Propionate (FP) in Adult Subjects with Partly Controlled and Uncontrolled Asthma. Individual participation will be approximately 16 weeks, including 12 weeks of double-blind treatment.
The primary outcome measure is FEV1 (Forced Expiry Volume in 1 second) and the secondary outcome measure is Peak Expiratory Flow Rate (PEFR), Asthma Control Questionnaire (ACQ), Nighttime awakenings and rescue medication usage.
Inclusion Criteria:
1. A signed and dated written informed consent form prior to the conduct of any study procedures
