Long-acting Beta Agonist Step Down Study - Full Text View

Purpose

This study is a 56-week, multi-center, blinded, randomized, double-masked parallel group comparative effectiveness study of approaches to stepping down therapy for patients with well-controlled asthma treated with combination ICS and LABA.

Primary Outcome Measures:

Treatment Failure [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
Rate of treatment failures assessed by decline in peak flow or FEV1, increased need for beta agonists, requirement for non-scheduled medical care for asthma symptoms, or prednisone taper.

Secondary Outcome Measures:

Pulmonary Function [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
Pulmonary function measures: 1)morning peak expiratory flow rate (from the patients' daily diary cards) and 2)pre-BD FEV1 and bronchodilator response
Rate of episodes of poor asthma control [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
Rate of episodes of poor asthma control (EPAC) defined by unscheduled medical care, hospitalization, use of oral corticosteroids and/or increased use of rescue medications and/or decrease of 30% or more in morning PEFR

Detailed Description:

Current asthma guidelines recommend stepping down therapy once asthma is controlled for at least 3 months. For patients treated with inhaled corticosteroids (ICS) alone, a dose reduction of 25-50% to a minimal dose that controls disease is recommended. The optimal approach to reducing treatment in patients with asthma treated with combination inhaled corticosteroids and long-acting beta agonists (ICS/LABA) is not clear. The American Lung Association Asthma Clinical Research Center (ALAACRC) is a network of 18 asthma research centers with the goal of performing clinical trials directly relevant to clinical practice. The question of the optimal way to de-escalate therapy in patients with asthma that is well controlled on fixed dose combination ICS/LABA is a key question for practitioners caring for patients with moderate to severe persistent asthma. We propose a 56 week multi-center, prospective, randomized, three-arm parallel group comparative effectiveness study comparing three approaches to care of patients with asthma well-controlled for three months on combination ICS/LABA: reduction of ICS dose and maintenance of LABA, initial discontinuation of LABA with continuation of ICS, and continuation of stable dose ICS/LABA. Our primary goal is to perform a pragmatic study that resembles clinical practice and determine the optimal treatment strategy that results in the lowest rate of treatment failure over 48 weeks of follow-up. Additional exploratory analyses include assessing risk factors for step-down failure, and to assess the duration of time that asthma control is maintained when therapy is de-escalated.

Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

age 12-80 years
physician diagnosed asthma that is well-controlled on moderate dose ICS/LABA based on an Asthma Control Test (ACT) score more than or equal to 20, and the absence of unscheduled visits or use of rescue prednisone for 4 weeks prior to enrollment
pre-bronchodilator FEV1 more than or equal to 70% predicted

Exclusion Criteria:

chronic oral steroid therapy
hospitalization or urgent care visit within 4 weeks of the screening visit

high risk of near fatal or fatal asthma
history of known premature birth less than 33 weeks or any significant level of respiratory care including prolonged oxygen administration or mechanical ventilation during the neonatal period
unstable cardiac disease (decompensated CHF, unstable angina, recent MI, atrial fibrillation, supraventricular or ventricular tachycardia, congenital heart disease, or severe uncontrolled hypertension)
other major chronic illnesses which in the judgment of the study physician would interfere with participation in the study e.g. including but not limited to uncontrolled diabetes, uncontrolled HIV infection or other immune system disorder
