Call for Horses with Heaves


    If your horse has been diagnosed with recurrent airway obstruction RAO or summer pasture obstructive pulmonary disease (SPAOPD) and you would like to participate in the two-phase, FDA-regulated, placebo controlled double-blind study of an investigational drug, please see contact information below to get requirements and discuss possible inclusion in this study.


    Participation is free as are all diagnostic tests and evaluations required for the study.  The study investigator will come to your location during Phase 1, so no travel is required.  If you participate in Phase 2, some travel with your horse may be required. More details about the study can be found at
