About this trial

This phase III trial compares the effect of vaginal fractional CO2 laser therapy to placebo for the treatment of vaginal dryness in breast cancer survivors with symptoms of genitourinary syndrome of menopause (GSM). Placebo therapy is an inactive treatment that is designed to mimic as closely as possible the active treatment being studied in a clinical trial. In this trial, patients will not be told whether they will be in the laser treatment group or the placebo group until 6-weeks after the third treatment visit (patient-blinded). At that point, patients who received placebo can elect to receive laser treatment similar to the other group. GSM is group of symptoms that affect the female genital and urinary systems and results from the lack of estrogen. Vaginal dryness can be commonly experienced with normal aging, with menopause, or come about from medications used to treat breast cancer such as chemotherapy or endocrine therapies like tamoxifen or aromatase inhibitors. Vaginal fractional CO2 laser therapy may help reduce vaginal dryness. compared to placebo.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Women with a history of breast cancer who have not had exposure to chemotherapy, targeted therapy, immunotherapy and/or radiation) within 3 months prior to registration.

Breast cancer survivors not currently on therapy are eligible

Patients may be receiving ongoing endocrine therapy These patients must be receiving adjuvant endocrine therapy prior to registration and intend to continue the same endocrine therapy for the 4 months while they are receiving protocol treatment, unless a clinically necessary change is indicated at the discretion of the patient's medical oncologist.

Patients on targeted therapy such as CD4/6 inhibitors are not eligible. Patients receiving concurrent chemotherapy and immunotherapy are not eligible.

Disqualifiers

Trial outcomes

Primary outcomes

1

Changes in patient reported vaginal dryness severity

Will use an 11-point (0-10 scale) numerical analog scale to assess patient reported severity of vaginal dryness. Higher scores represent worse symptoms (0: None - 10: Worst possible). The vaginal dryness scores at each time point will be summarized separately by treatment arm using the mean (standard deviation) and median (range). The score changes from baseline to the 18-week time point (T4) will be compared using two-sample t-test or Wilcoxon rank-sum test as appropriate.

Time frame
Up to 18 weeks

Secondary outcomes

1

Changes in vaginal discomfort during sexual activity (for sexually active subset of study population only)

Assessed using the Vaginal discomfort domain of Patient Reported Outcomes Measurement Information System (PROMIS) Sexual Function version (V) 2.0 Brief Profile - Female (only the sexually active women will be evaluable for this, which is estimated to be approximately 50% of the population). Higher scores represent more discomfort (1: None - 5: A lot). Change in the vaginal discomfort domain of the PROMIS Sexual Function v. 2.0 Brief Profile-Female from baseline to each post-therapy-initiation time point will be summarized by treatment arm and will be compared as described for the primary endpoint.

Time frame
Baseline up to 24 months after completion of treatment
2

Change in quality of life

Evaluated using 11-point (0-10) numerical analog scale. Higher scores represent better quality of life (0: As bad as it can be - 10: As good as it can be). Change in patient reported quality of life from baseline to each post-therapy initiation time point will be summarized and compared as described for the primary endpoint.

Time frame
Baseline up to 24 months after completion of treatment
3

Incidence of adverse events associated with vaginal fractional CO2 laser therapy

Incidences of toxicities in the fractional CO2 laser therapy arm will be summarized by type. Common toxicities that occur in both arms will be summarized and compared between arms using the Chi-square test or Fisher's exact test, as appropriate.

Time frame
Up to 24 months after completion of treatment
