The Vulvar Vestibulitis Clinical Trial (VVCT) is a randomized, placebo-controlled, double-blinded clinical trial to study the clinical efficacy of four medical treatments for vulvar vestibulitis: 1) topical lidocaine, 2) oral desipramine, 3) combined lidocaine and desipramine, and 4) placebo cream and capsules. The duration of study drug will last 12 weeks with post-intervention follow-up at 6 and 12 months. We plan to enroll 128 subjects from the university-based clinical program at the University of Rochester (UR).Primary outcome variable will compare the reported pain of the "Tampon Test" (mean of Weeks -2, -1, and 0), prior to randomization to the reported pain of "Tampon Test" (mean of Weeks 10, 11, and 12). The dependent (primary outcome) variable will be defined as the percent change of mean "Tampon test" pain of Weeks (10, 11, and 12) from Weeks (-2, -1 and 0). The primary analysis of this 2X2 factorial design will involve fitting an Analysis of Covariance (ANCOVA) regression model to the percent change of mean "Tampon test" pain with the two treatment variables as the predictors while adjusting for the covariate age. We will test if the interaction between the two treatments in the ANCOVA model is significant at the .05 level. If the interaction effect is not significant, it will be dropped from the model and the conclusion will be drawn from the model with main effects only. If significant, the model with interactions will be adopted. SAS PROC GLM will be used in the analysis.
