Trial of Roflumilast in Asthma Management (TRIM) (TRIM)

There are currently no treatments to specifically target asthma in obese adults. This pilot study is being conducted to investigate how effective roflumilast is in treating asthma in participants that have a higher BMI. Roflumilast can induce weight loss, which may lead to improved asthma control.

The primary objective of TRIM is to perform a pilot placebo-controlled trial of roflumilast for the treatment of poorly controlled obese asthmatics.

Study Overview

• Status: Completed
• Conditions: Obesity; Asthma
• Intervention / Treatment: Drug: Roflumilast 500 Mcg Oral Tablet; Drug: Placebo oral capsule

Detailed Description

TRIM is a 24 week, randomized, double-masked, placebo controlled trial that will enroll 38 participants.

This study will be take place in seven centers of the American Lung Association- Airways Clinical Research Centers (ALA-ACRC). The centers include: Northwestern University Feinberg School of Medicine, Mount Sinai Icahn School of Medicine, Duke University, University of Arizona, the University of Vermont, The University of Alabama Lung Health Center, and University of Illinois Breathe Chicago Center. Johns Hopkins University will be the Data Coordinating Center (DCC) for the trial.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Asthma Control Test Score	The Asthma Control Test was designed to help participants describe their asthma and how it affects how they feel and what they are able to do. They choose a response based on their asthma within the last 4 weeks. Participants select how many times per week they experience different asthma symptoms and how often they had to use a rescue inhaler or nebulizer. There are 5 questions with 5 responses; 1 meaning their asthma is not well controlled or they had symptoms more frequently, through 5 meaning they feel their asthma is well controlled or they do not experience any symptoms. The primary outcome is an unadjusted comparison of 24 week change in Asthma Control Test scores between the treatment groups.	Baseline and 24 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Weight	Weight change measured in kilograms (kg).	Baseline and 24 weeks
Change in Asthma Symptom Utility Index (ASUI)	A 10-item questionnaire, patient preference-based scale assessing frequency and severity of selected asthma-related symptoms and treatment side effects, for use in clinical trials and cost-effectiveness studies in asthma. Range is 0-1. Higher score is indicative of better health.	baseline and 24 weeks
Change in Gastrointestinal Symptom Rating Scale (GSRS)	It has 5 subscales (Reflux, Diarrhea, Constipation, Abdominal Pain, and Indigestion Syndrome). Subscale scores range from 1 to 7 and higher scores represent more discomfort and poor health.	Baseline and 24 weeks
Change in Generalized Anxiety Disease (GAD-7)	GAD-7 has 7 questions. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of 'not at all', 'several days', 'more than half the days', and 'nearly every day', respectively, and adding together the scores for the seven questions. The following cut-offs correlate with level of anxiety severity: Score 0-4: Minimal Anxiety Score 5-9: Mild Anxiety Score 10-14: Moderate Anxiety Score greater than 15: Severe Anxiety	baseline and 24 weeks
Change in Marks Asthma Quality of Life Questionnaire	20 items with 2 week recall. Self-administered questionnaire intended for use with adults. Respondents are asked to describe how troubling particular items have been over the past four weeks. Covers both physical and emotional impact. Range 1-4. lower score is indicative of better health	baseline and 24 weeks
Change in SF 36	The 36-Item Short Form Health Survey (SF-36) is a set of generic, coherent, and easily administered quality-of-life measures. Range 0-100. Higher score is indicative of better health.	baseline and 24 weeks
Change in PHQ9	The PHQ-9 (Patient Health Questionnaire-9) objectifies and assesses degree of depression severity via questionnaire. It has 9 questions. Range 0-27, lower score is indicate of better health.	baseline and 24 weeks
