I think it's worth a try.
/entyviohcp.com/efficacy-crohns-disease/Not the strongest results with Crohn's, but there aren't tons of options. What else are you considering? I've heard of some people trying Stelara as well... Xeljanz might be possible. I tried entyvio and had no success. It's not considered a rescue medication, so you have to be patient and give it a few months before you know whether it's working. I knew it wasn't working because I went from feeling well to a full on flare up while taking it - over the course of months.
