Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a 24-week, randomized, parallel group comparative effectiveness study to evaluate the risk of stepping down therapy for patients with well-controlled asthma treated with combination Inhaled corticosteroids (ICS) and Leukotriene receptor antagonist（LTRA).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Asthma guidelines recommend stepping down therapy once asthma is controlled for at least 3 months. Leukotriene receptor antagonist（LTRA). For children with mild persistent asthma, ICS twice a day combined with LTRA can be used for treatment, but there is no consensus on how to reduce drugs in patients with asthma that is well controlled (reducing the dose of ICS or stopping montelukast). We propose a 24-week, randomized, parallel group comparative effectiveness study comparing three approaches in patients with asthma well-controlled for at least three months on combination ICS and LTRA: Halve the dose of ICS firstly and then stop ICS with montelukast only, stop montelukast firstly and then halve the dose of ICS, and halve the dose of ICS firstly and then stop montelukast. Our goal is to compare the rate of treatment failure and determine the optimal treatment strategy. Additional goals include assessing risk factors for step-down failure.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Stop Fluticasone propionate Inhaled Aerosol Firstly

Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day，and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day

Group Type ACTIVE_COMPARATOR

Fluticasone propionate inhaled aerosol

Intervention Type DRUG

The study consists of two stages and include three groups. Three groups include: Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day，and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day; Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day，and then stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug once a day; Stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug twice daily, and then Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day. The scheme of every group is divided into two stages. Only those whose asthma are well controlled at the end of the first phase will be allowed to proceed to the next phase.

Stop Montelukast Secondly

Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day，and then stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug once a day
