Objective. To determine whether a single dose of Clindesse™ vaginal cream is comparable in efficacy and safety to Cleocinmml®
vaginal cream administered once daily for 7 days in the treatment of bacterial vaginosis.Study design. This multicenter, randomized, single-blind, parallel-group study enrolled 540 patients with BV infections. Treatment consisted of either a single intravaginal dose of Clindesse™ or 7 daily doses of Cleocin® . Efficacy and safety were assessed 21–30 days after the start of treatment. The efficacy endpoints were Investigator Cure, Clinical Cure (a composite of all 4 Amsel's criteria and Investigator Cure), Nugent Cure (Nugent score <4), and Therapeutic Cure (a composite of Clinical Cure and Nugent Cure). Resolution of individual Amsel's criteria was also evaluated. Treatment-emergent adverse events were monitored throughout the study.Results. There were no significant differences in cure rates between the Clindesse™ and Cleocin® treatment groups in Investigator Cure (P = 0.702), Clinical Cure (P =0.945), Nugent Cure (P = 0.788), or Therapeutic Cure (P = 0.572). Results were also similar for 3 of 4 and 2 of 4 Amsel's criteria and for each individual Amsel's criterion (all P-values >0.200). Ninety-five percent confidence intervals for each endpoint were consistent with equivalence between the 2 products. There was no significant difference between the treatment groups in the incidence of treatment-emergent adverse events (P = 0.386).Conclusions. A single dose of Clindesse™ vaginal cream is equivalent in safety and efficacy to a 7-dose regimen of Cleocin® vaginal cream in the treatment of bacterial vaginosis. This represents a significant advance in the treatment of bacterial vaginosis.
