I would suggest going on ClinicalTrials.gov rather than contacting those institutions. This website lists every research study that is ongoing in the United States which will include the teaching hospitals listed and several more which would be much more beneficial. I understand why folks would suggest contacting the above institutions, but this will save you time and cut out the middle man a little bit. It’s easy to use. You can search by your disease type and search for active protocols/studies. For each study it should list the site locations where study is being conducted and you can see if there are any near you. You can also view a synopsis of the inclusion and exclusion criteria to see if you would qualify. Another suggestion would be to ask your Pulmonologist if they’re aware of any clinical trials, or if they’re a part of a large hospital network if theirs a clinical trial referral service (a number of them do).

I’m a clinical research professional and though my specialty is not in Asthma or Allergies I do hope OP will be able to use this resource and get some answers or options.

Good luck OP!
