Hi,
basing on the info you provided, the advise one can give you depends on an answer to the question: should the information for the trial be structured in any way or it might be a free text.
In the last case the BLOB (CLOB) column would help you. There you can hold any unstructured information└
The requirement to have information structured, makes your life much more complicated. There are different approaches you can use, each depends on the business task you have (how the information should be structured). If you are in this case, pls provide more information to give you some valueable advise

regards
  Evgen
