The first screening if you will was a basic questionnaire that my doctor gave to me to fill out. Since my doctor is apart of the study, I didn't have to submit any paper work as he confirmed everything and I did a hearing test at his office which confirmed that I had hearing loss.
The questions ranged from, did you have tinnitus for the last two weeks, to has the pitch changed etc. Various questions in regards to how loud it may be, what sort of a sound it seems like, if it is one noise or multiple noises. I assume dependent on your answers you can be removed from the trial before it begins.
The actual first evaluation where I went to the office was more or less basic review of these questions but this time I had to answer them again and in a bit more detail. Describing the noises I hear, etc. Basic blood work, Hearing test, and a doctor screening to rule out any issues. I assume to rule out any other medical issues you may or may not have that could cause the results to vary. They also go over that you are not allowed to take any herbal, supplements or medicines that are recommended for tinnitus. Lipoflavinoids (I know they dont work) but you cannot take them, as well as some other medicines I have to check the list but if you are in the screening they will give you a card)
Last they give you an electronic diary in which you fill out questions each night. You must answer it each might (I almost forgot to enter last night actually). It is to monitor to check I suppose your progress throughout the 100 days.
I will update once I get my first injection on Monday.
