Hi Debbiecartwright and thanks for your post/inquiry.
If you and your husband are interested in participating in clinical trials, I thought it might be helpful to you to review this article on that very topic which is published right here on COPD.net - https://copd.net/clinical/patient-voice-clinical-trial-development/.
I hope this provides you with a bit more insight for your concerns.
All the best,
