The drug was relatively well tolerated. It seems to be 2-3 times more effective than the CRABs. I read speculation that one would or could continue the weekly CRAB infusion and that Antegren would be administered every four week via IV.
Here are the stats from Phase II data:
Although data from the pivotal phase III trials are not yet widely available, phase II trial data from earlier studies in multiple sclerosis patients showed evidence of Antegren's efficacy. In comparison with placebo, patients treated with infusions of Antegren for six months had many fewer new enhancing lesions on MRI (85% to 95% reduction) and fewer clinical relapses (45% to 75% reduction).
