Official title
A Multi-center, Randomized, Double-blind, Placebo-controlled Trial of Topical Ketotifen Fumarate 0.25% Cream for Females With Secondary Vestibulodynia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a Phase 2, multi-center, randomized, double-blind, placebo-controlled trial evaluating the safety and efficacy of topical ketotifen fumarate 0.25% cream in adult women with secondary provoked vestibulodynia (PVD). Secondary PVD is a chronic vulvar pain condition characterized by burning or sharp pain with vaginal penetration (e.g., intercourse, tampon use) and touch of the vulvar vestibule, often following recurrent infections or topical irritant exposures. Preclinical studies suggest that ketotifen, a mast-cell stabilizer and histamine H1 antagonist, may reduce neuroinflammation and abnormal nerve growth in the vulvar vestibule, offering a mechanism-based, non-surgical treatment option. Approximately 54 women aged 18 years and older who meet ISSVD/ISSWSH/IPPS criteria for secondary PVD without vulvovaginal atrophy will be enrolled. After a 1-week screening period, all participants will complete a 2-week single-blind placebo run-in; those with a strong placebo response or intolerance to vehicle cream will not be randomized. Eligible participants will then be randomized 1:1 to receive ketotifen fumarate 0.25% cream or matching placebo cream applied twice daily to the vulvar vestibule for 12 weeks. The primary outcome is change from baseline to Week 15 in pain intensity with the baseline dilator maximum tested size (DMTS), measured on an 11-point numeric rating scale. Secondary outcomes include changes in Vulvodynia Experience Questionnaire (VEQ) scores, vestibular pain thresholds measured by Wagner algometry, and participant-reported meaningful benefit at the end of treatment. Safety assessments will include adverse events, application-site reactions, physical examinations, vital signs, and pregnancy testing. This study will provide the first controlled clinical data on topical ketotifen for secondary PVD and inform the feasibility of larger registration trials.
