"PharmaFrontiers Corp. announced today that the protocol for its Phase IIb clinical trial of Tovaxin(TM), a novel T cell therapeutic vaccine for Multiple Sclerosis (MS), has been accepted by the U.S. Food and Drug Administration's (FDA) Center for Biologics Evaluation and Research (CBER). PharmaFrontiers is very excited to receive a 'green light' from the FDA for our Phase IIb clinical trial. Our earlier open-label Phase I/II clinical trials not only gave us the safety and tolerability data we sought, but we also observed a trend towards a reduction in annualized relapse rate (ARR) in excess of 90%, the lowering of the myelin-peptide reactive T cells (MRTCs) in patients blood and the improvement in patients' clinical measures," said David B. McWilliams, chief executive officer of PharmaFrontiers."MORE: "Phar"
