Brief Summary:

A 14-week, randomized, placebo-controlled, double-masked clinical trial in 40 obese patients with poorly controlled asthma.

The intervention is Mitoquinol (MitoQ) versus placebo.

The primary aim of this pilot study is to determine if MitoQ improves airway reactivity in obese patients with asthma.

Condition or disease Intervention/treatment Phase
Asthma Obesity Drug: Mitoquinol Drug: Placebo oral tablet Phase 1

Detailed Description:

Study aim:

The objective of this proposal is to conduct a pilot clinical trial to determine if the mitochondrial-targeted anti-oxidant MitoQ improves airway reactivity in obese patients with poorly controlled asthma.

Type of Study:

A 14 weeks, prospective, two center (Duke and the University of Vermont), randomized, placebo-controlled, double-masked clinical trial.

Study Population:

40 patients with obesity and poorly controlled asthma.


MitoQ 40 mg per day versus placebo.

Primary Outcome Measures :
  1. change in airway reactivity [ Time Frame: Through study completion, 12 weeks ]
    airway reactivity to methacholine

Secondary Outcome Measures :
  1. Change in 8-isoprostanes. [ Time Frame: Through study completion, 12 weeks ]
    serum, sputum and nasal lavage 8-isoprostanes

  2. sputum cell counts. [ Time Frame: Through study completion, 12 weeks ]
    change induced sputum cell counts

  3. Asthma Control Test (ACT) [ Time Frame: Through study completion, 12 weeks ]
    To collect data on asthma symptoms measured by asthma control questionnaire determined by a score from 5-25 (the lower the score, the worse the asthma symptoms)

  4. Adherence [ Time Frame: Through study completion, 12 weeks ]
    pill counts

  5. Asthma quality of life questionnaire. [ Time Frame: Through study completion, 12 weeks ]
    The Marks Asthma Quality of Life Questionnaire (Marks AQLQ). Minimum score of 20, maximum score of 100. The greater the score, the more asthma is affecting quality of life. Minimum score is 5, maximum score is 35. The greater the score, the more severe the asthma symptoms.

  6. Asthma Symptom Utility Index [ Time Frame: Through study completion, 12 weeks ]
    The Asthma Symptom Utility Index (ASUI), a 2-week utility-weighted asthma symptom questionnaire. Used to collect data on frequency and severity of asthma symptoms.

  7. Lung function FEV1 [ Time Frame: Through study completion, 12 weeks ]

  8. Lung function, FVC [ Time Frame: Through study completion, 12 weeks ]

  9. change in lung impedance [ Time Frame: Through study completion, 12 weeks ]
    measured by forced oscillation

  10. Adverse effects [ Time Frame: Through study completion, 12 weeks ]
    assessed at each study visit
