Brief Summary:
The purpose of the study is to find out if taking vitamin D in addition to an asthma controller medication helps to prevent worsening of asthma symptoms and asthma attacks.

Condition or disease Intervention/treatment Phase
Asthma Drug: Vitamin D3 Drug: Ciclesonide Phase 3

Detailed Description:
This is a randomized, double-blind parallel group trial that will enroll individuals who have vitamin D insufficiency and asthma with persistent symptoms despite low-dose inhaled corticosteroid. Participants on low-dose inhaled corticosteroid will be randomized to add-on therapy with either placebo or high-dose vitamin D for a 28-week period. During the inhaled corticosteroid-stable phase, participants will remain on low-dose inhaled corticosteroid. During the inhaled corticosteroid-taper phase, participants will taper their inhaled corticosteroid by 50% at two time-points post-randomization. The investigators will determine if the addition of vitamin D reduces the likelihood of treatment failure when compared to placebo during both the inhaled corticosteroid-stable and inhaled corticosteroid-taper phases of the study. Given the high prevalence of both vitamin D insufficiency and asthma, this trial has high potential to impact daily asthma management.

Arm Intervention/treatment
Placebo Comparator: Ciclesonide + placebo Drug: Ciclesonide
Low dose inhaled corticosteroid (80 mcg/puff two puffs twice daily)
Other Name: Alvesco®

Experimental: Ciclesonide + Vitamin D Drug: Vitamin D3
vitamin D (100,000 IU loading dose followed by 4,000 IU/day)

Drug: Ciclesonide
Low dose inhaled corticosteroid (80 mcg/puff two puffs twice daily)
Other Name: Alvesco®

Primary Outcome Measures :
  1. Treatment Failure [ Time Frame: Twenty-eight week intervention period from randomization until end of trial. ]
    Treatment failure is a well-defined asthma outcome reflecting overall asthma control that has been used previously in multiple clinical trials. Treatment failure as defined in the current proposal and prior trials is consistent with the American Thoracic Society (ATS)/European Respiratory Society(ERS) definition of a moderate exacerbation - a deterioration in symptoms and/or lung function with increased rescue bronchodilator use that lasts 2 days or more. The percentages of participants experiencing a treatment failure are Kaplan-Meier estimates of failure rate.

Secondary Outcome Measures :
  1. Lung Function Change From Baseline [ Time Frame: Change is measured as value at 28 weeks minus baseline value. ]
    FEV1 (liters) and methacholine PC20 will be evaluated. Changes are measured as 28 weeks minus baseline.

  2. Exacerbations [ Time Frame: Overall exacerbation rate during 28-week trial ]
    Outcome defined as number of exacerbations per person-year.
