new UC med

My GI told me about a new med that is suppose to be approved in July.  I guess it is a 5ASA drug but more targeted to release half way through your colon.  So those of us who have left-sided colitis will benefit most from this.  He says that it is more targeted and I will get to take much less of the drug than the present 9 colazal I am taking now.  Sounds good to me, but does anyone know about this.  I can't remember the name of it?  and I wanted to look into it before my next scope so we can discuss it.

I haven't heard anything about a new 5-ASA. I know there are late-stage studies going on with a new combination drug that includes prednisone and a 4-ASA, Colazal I believe.
