Results from the Phase I / II Tovaxin trial are to be presented at the ACTRIMS / ECTRIMS conference at the end of September / early October 2005. Tim who is participating in the trial has posted his experience on this site - and has seen good results. Unlike the ABCRs this treatment does appear to improve EDSS ratings which, to me, is more important than relapse rates (although Tim has not experienced a relapse since starting on the trial in late 2003).
I contacted the company about participation in the phase IIb / III trial but was told that there were no plans at present for trials in the UK. Trials will be taking place in the US (maybe Canada?).
