BioSante Bio-E-Gel Phase III data
BioSante plans an NDA submission for its transdermal estradiol gel Bio-E-Gel "as soon as possible" following positive results from a Phase III trial in menopausal women. The 12-week, 484-patient study looked at three dose levels. Beginning at week five, highly significant decreases in the number (p<0.001) and severity (p<0.01) of hot flashes compared to placebo were observed with the lowest study dose.
