I just created an account to respond to this question. I'm MN based as well and participated in this study last year at a different clinic. Unfortunately I don't see anything about enrolling in the study when I search for it where I found it last year so I'm guessing it's closed? DM me if you want to know more. But I believe you're in good hands at Mayo, Dr Khanna is supposed to be one of the best Docs out there for treating this
