Clobetasol propionate, Fractionated CO2-laser
Brief summary
This is a randomized placebo-controlled trial design to determine whether combining FxCO2-laser with the traditional therapy of clobetasol propionate 0.05% ointment (combined treatment) as compared to FxCO2-laser and placebo ointment (FxCO2-laser only) will improve treatment response in women undergoing FxCO2-laser for vulvar lichen sclerosus. Primary objective: To evaluate if women with LS who undergo FxCO2 laser therapy and concomitant TCS (clobetasol group) have higher treatment success (defined as a MCID of a ≥16 point improvement in Skindex-29 questionnaire) than those who undergo FxCO2 laser and placebo ointment (placebo group). * Hypothesis: A higher proportion of women randomized to clobetasol will achieve treatment success as compared to those randomized to placebo. * Approach: The proportion of women in each cohort who obtain a ≥16 point improvement in Skindex-29 validated questionnaire score from baseline to final visit will be compared. Secondary objectives: To compare change in pre- and post-treatment scores on validated questionnaires measuring vulvovaginal symptoms, sexual function, lower urinary tract function, and genital self-image between the clobetasol group compared to the placebo group. * Hypothesis: Women randomized to clobetasol will demonstrate an equal or greater improvement on validated quality of life questionnaires measuring vulvovaginal symptoms, sexual function, lower urinary tract function, and genital self-image as compared to women randomized to placebo. * Approach: Change scores will be calculated to determine change per participant over the treatment period and mean change scores will be compared between cohorts.
Interventions
All women will be undergoing FxCO2-laser therapy as this treatment is a criterion for enrollment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment success | About 5 months (baseline to final visit) | Minimally clinically important difference of a ≥16 point improvement in Skindex-29 validated questionnaire score. Skindex-29 responses are transformed to a linear scale from 0 (no effect) to 100 (effect experienced all the time), and are reported as three scale scores, corresponding to three domains (symptoms, emotions, and functioning). A reduction in Skindex-29 score of 16 points or more has been shown to indicate what is considered a clinically meaningful improvement. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Treatment response - sexual function | About 5 months (baseline to final visit) | Treatment response - sexual function will be measured by pre- and post-treatment scores on the Female Sexual Function Index, a validated questionnaire to assess sexual function. |
| Treatment response - genital self image | About 5 months (baseline to final visit) | Treatment response - genital self image will be measured by pre- and post-treatment scores on the Female Genital Self Image Scale, a validated survey with scores ranging from 7-28 with higher scores indicate a more positive genital self-image. |
| Treatment response - vulvovaginal symptoms | About 5 months (baseline to final visit) | Treatment response - vulvovaginal symptoms will be measured by pre- and post-treatment scores on the vulvovaginal Symptoms Questionnaire, a 21-item survey measuring vulvovaginal symptoms in postmenopausal women. |
| Participant-perceived improvement | Final study visit at 4-6 weeks after third Fractionated CO2 laser treatment - one time question | Patient Global Impression of Improvement (PGI-I): a one single item question that will ask participants to rate their improvement after undergoing treatment on a 7-point Likert scale ranging from very much worse to very much better. |
| Participant-perceived treatment satisfaction | Final study visit at 4-6 weeks after third Fractionated CO2 laser treatment - one time question | Level of satisfaction with treatment: a one single item question that will ask participants to rate their level of satisfaction with treatment on a 5-point Likert scale from very dissatisfied to very satisfied. |
| Treatment response - lower urinary tract function | About 5 months (baseline to final visit) | Treatment response - lower urinary tract function will be measured by pre- and post-treatment scores on the LURN SI-10, a 10-item questionnaire with scores ranging from 0 to 38 (higher scores = worse symptoms/bother). |
