I have a few suggestions...Lialda, Asacol HD, LDN, Apriso, Pentasa, Medical Marijuana, The SCD diet, Cimzia ( if it is not a problem with PML for you) Slippery elm, Bee propolis, Cyclosporin, Prograf or 6MP. If you could buy some time, the new drug vedolizumab will be coming out soon. Liquid diet can be helpful for some people.
Hope something I listed can help you!
Hugs!
