Many thanks! I think you might actually be the first person to post the results of this study of naltrexone. This is the recently completed phase 2 study conducted at Penn State, not the pilot study published in 2007. This has some good hard data since they did biopsies before and after. A 45% remission rate is very respectable, given that it is accompanied by endoscopic improvement. This is just an abstract, so I will be eager to see the results in detail when the study is fully published. By the way, for those following the studies of this medication, the phase 2 trial in children is also complete, but I haven't seen any abstract of the results yet.
