Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-09-10
• Study Completion Date: 2021-09-10

Brief Summary

This phase II trial studies how well carbon dioxide fractional (CO2RE) laser works in treating participants with stage 0-III hormone receptor-positive breast cancer with vulvovaginal atrophy associated with dryness, inflammation or thinning of the epithelial lining of the vulva and vagina. CO2RE laser is a device that delivers controlled CO2 energy to the vaginal tissue and may help treat vaginal symptoms such as itching, burning, painful sexual intercourse, thickened or thin skin of the vulva, and stinging.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the reduction in Vulvovaginal Symptom Questionnaire (VSQ) score at 3-month follow up after CO2RE laser treatment.

SECONDARY OBJECTIVES:

I. To evaluate the reduction in VSQ score after CO2RE laser treatment 6-month follow-up and 12-month follow-up.

II. To evaluate Female Sexual Function Index (FSFI) score before and after treatment with CO2RE laser.

III. To evaluate Urogenital Distress Inventory (UDI) 6 score before and after treatment with CO2RE laser.

IV. To evaluate vaginal health index score and vaginal caliber before and after treatment with CO2RE laser.

V. To evaluate discomfort and pain during CO2RE laser treatment using the visual analog scale.

VI. To evaluate treatment satisfaction after CO2RE laser treatment using 5-point Likert scale.

VII. To evaluate adherence to aromatase inhibitor at 6 and 12 months after CO2RE laser treatment.

EXPLORATORY OBJECTIVES:

I. To assess the change in the vaginal cytology using vaginal maturation index at baseline and during follow-up.

II. To assess serum estradiol level at baseline and after CO2RE laser treatment.

OUTLINE:

Participants undergo carbon dioxide fractional laser therapy over 10-15 minutes on day 1. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up at 3, 6, and 12 months.

Eligibility Criteria

Inclusion Criteria

• Histological confirmation of adenocarcinoma of the breast stage 0-III
• Evidence of hormone sensitivity with estrogen receptor (ER) and/or progesterone receptor (PR) positive >= 1% of primary tumor tissue
• Currently or will be starting on aromatase inhibitor (letrozole, anastrozole, or exemestane)
• Willingness to self-report vaginal itching, dryness, or dyspareunia
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1 or 2
• Obtained =< 28 days prior to registration: Hemoglobin >= 8.0 g/dL
• Obtained =< 28 days prior to registration: Absolute neutrophil count (ANC) >= 1500/mm^3
• Obtained =< 28 days prior to registration: Platelet count >= 75,000/mm^3
• Obtained =< 28 days prior to registration: Total bilirubin =< 3.0 x upper limit of normal (ULN)
• Obtained =< 28 days prior to registration: Aspartate transaminase (AST) =< 3 x ULN
• Obtained =< 28 days prior to registration: Prothrombin time (PT)/international normalized ratio (INR)/activated partial thromboplastin time (aPTT) =< 2 x ULN OR if patient is receiving anticoagulant therapy and PT/INR or partial thromboplastin time (PTT) is within therapeutic range of intended use of coagulants
• Obtained =< 28 days prior to registration: Calculated creatinine clearance =< 3 x ULN
• Recent negative Papanicolaou (PAP) smear within 1 year. In patients who do not have recent PAP smear, PAP smear should be obtained as per standard of care during the screening process prior to enrollment
• Ability to complete questionnaire(s) by themselves or with assistance
• Provide written informed consent
• Willing to return to enrolling institution for follow-up (during the active monitoring phase of the study)

Exclusion Criteria

• Previous use of CO2 fractional within 1 year
• Receiving any form of hormone replacement therapy, including topical estrogens, testosterone, and dehydroepiandrosterone (DHEA) or selective estrogen receptor modulator (SERM), including tamoxifen and ospemifene
• History of or current dysplastic nevi in the area that will be treated
• Prolapse uterus > stage II according to the International Continence Society pelvic organ prolapse quantification (ICS-POP-Q) system
• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of the treatment
• Immunocompromised patients and patients known to be human immunodeficiency virus (HIV) positive and currently receiving antiretroviral therapy. NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Evidence of urinary tract infection (UTI) based on the urinalysis (UA) at the time of the screening. Patients with evidence of UTI can be enrolled after UTI is treated and repeated UA and/or urine culture shows no further evidence of ongoing infection
• Evidence of injuries, bleeding, or evidence suggestive of dysplasia in the external vaginal area or vaginal canal

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
