NCT05379153

Brief Summary

This phase III trial tests whether vaginal fractional CO2 laser therapy works in treating vaginal dryness in breast cancer survivors. 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.

Outcome Measures

Primary Outcomes (1)

  • Changes in patient reported vaginal dryness severity

    Will use an 11-point (0-10) 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.

    Up to 18 weeks

Secondary Outcomes (3)

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

    Baseline up to 24 months after completion of treatment

  • Change in quality of life

    Baseline up to 24 months after completion of treatment

  • Incidence of adverse events associated with vaginal fractional CO2 laser therapy

    Up to 24 months after completion of treatment

Study Arms (2)

Arm I (vaginal fractional CO2 laser therapy)

EXPERIMENTAL

Patients undergo vaginal fractional CO2 laser therapy over 20-30 minutes every 6 weeks for 3 treatments in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women with a history of breast cancer treated with curative intent who have completed primary therapy (consisting of surgery with or without chemotherapy, targeted therapy, immunotherapy and/or radiation) \>= 12 months prior to registration. Concurrent trastuzumab /pertuzumab is permissible
  • May be receiving ongoing adjuvant endocrine therapy (with an AI or tamoxifen +/- ovarian function suppression). Patients are not required to receive these treatments to be eligible. Participants receiving adjuvant endocrine therapy prior to registration must 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 aromatase inhibitor (AI) therapy, tamoxifen with or without ovarian function suppression therapy must have been on their current endocrine therapy regimen for at least 6 months prior to registration
  • Patient-reported vaginal dryness with or without dyspareunia of at least moderate severity on average, defined as \>= 4 on a 0-10-point scale that has been bothersome for \>= 3 months and for which the patient wants to undergo the study procedure
  • No evidence of metastatic breast cancer. Scans to assess for metastatic disease are not required for eligibility
  • No prior gynecologic cancer, vaginal intra-epithelial neoplasia, pelvic radiation or pelvic reconstructive surgery utilizing mesh. Patients with cervical intraepithelial neoplasia are eligible
  • No history of scleroderma, lupus, systemic sclerosis, mixed connective tissue disorder, undifferentiated connective tissue disorder or collagen vascular disease, dermatomyositis, polymyositis, lichen sclerosis or vulvar vestibulitis
  • No pelvic surgery that involved a vaginal incision within 6 months of registration. Patients who received laparoscopic BSO (Bilateral salpingooophorectomy) are eligible
  • No systemic estrogen or progesterone, vaginal estrogen, vaginal prasterone, ospemifene, and/or androgen therapy within 6 weeks prior to registration
  • No other suspected contraindications for undergoing laser therapy
  • No prior vaginal laser therapy at any time. Patients who would have completed any type of vaginal laser resurfacing procedure at any time prior to the start of study treatment are not eligible
  • No known concurrent invasive carcinoma/malignancy. Patients with carcinoma in situ are eligible. Patients with a prior malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible if not currently receiving treatment
  • Postmenopausal based on at least one of the following criteria at the time of registration:
  • Women 50 or older with no spontaneous regular menses \> 12 months
  • On ovarian suppression (i.e., gonadotrophin releasing hormone \[GNRH\] agonist/antagonist) for at least 6 months or greater, with plans to continue such treatment for at least 18 weeks
  • Bilateral oophorectomy
  • +5 more criteria
