Inhaled Iloprost in Mild Asthma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01209533
Recruitment Status : Completed
First Posted : September 27, 2010

Brief Summary:
The purpose of the study is to determine if inhaled iloprost given four times daily can improve symptoms and lung function in adults with mild asthma.

Condition or disease Intervention/treatment Phase
Asthma Drug: Iloprost Early Phase 1

Detailed Description:
Animal studies have suggested that prostacyclin may downregulate allergic inflammation, thus providing the scientific basis for trials of inhaled prostacyclin agonists such as iloprost for the treatment of asthma. This study will examine the tolerability of four times daily iloprost on asthma symptoms and pulmonary function over a two week treatment period.

Study Type : Interventional  (Clinical Trial)

Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Inhaled Iloprost in Mild Asthma
