VIDA- Vitamin-D Add-on Therapy in Asthma
This study will enroll individuals 18 years and older who have vitamin D insufficiency and asthma with persistent symptoms despite low-dose inhaled corticosteroid (ICS). Subjects on low-dose ICS will be randomized to add-on therapy with either placebo or high-dose vitamin D for a 28-week period. The purpose of this study is to find out if taking vitamin D in addition to an inhaled steroid will help prevent worsening asthma symptoms and asthma attacks.
You may be eligible to participate in this study if you:
- Have had physician-diagnosed asthma for at least past 12 months.
- Are a male or female, 18 years of age or older.
- Are on a stable asthma controller therapy (inhaled corticosteroid or leukotriene modifier only) dose for past 2 weeks.
- Are willing to practice birth control for duration of study (in addition to not currently being pregnant or breastfeeding for females)
