Because if you do a little bit of DD on the company's history and its main ingredient used (crofelemer, already approved and used on humans -HIV- and dogs -cancer-, for the preventive treatment of diarrhea with no side effects for long term use), you would assume there's little chance for the study not being successful. But, of course, this is not 100% certain, so i recommend doing your own DD.
