Vaginitis

April 1, 2002

Results were reported from a phase II randomized, placebo-controlled trial evaluating CTV-05, a strain of human Lactobacillus, for treatment of bacterial vaginosis. The drug was tested in over 400 female subjects as an adjunct to standard metronidazole therapy. Treatment with CTV-05 resulted in vaginal colonization by lactobacillus crispatus in 62% of subjects at 30 days, compared to only 2% of placebo subjects. However, clinical cure rates at 30 days, the primary endpoint of the trial, were not significantly improved with CTV-05 treatment. Satisfactory cure rates were reported in approximately 50% of subjects in both groups. Clinical cure at 30 days was observed in 70% of colonized subjects who received the active drug, compared to 47% who were non-colonized and received placebo, showing that while CVT-05 does not significantly improve cure rates, it does significantly increase colonization rates. CVT-05 is being developed by The Medicines Company.
