Brief Summary:
This phase I trial studies the side effects and best dose of bexarotene in preventing breast cancer in patients at high risk for breast cancer.

Condition or disease Intervention/treatment Phase
Atypical Ductal Breast Hyperplasia Atypical Lobular Breast Hyperplasia Ductal Breast Carcinoma In Situ Invasive Breast Carcinoma Lobular Breast Carcinoma In Situ Drug: Bexarotene Other: Laboratory Biomarker Analysis Other: Questionnaire Administration Phase 1

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the recommended phase II dose of topical bexarotene 1% (weight by weight [w/w]) gel for evaluation in healthy women. (Dose Escalation Group) II. Conduct an intervention of topical 1% bexarotene gel to an unaffected breast of healthy women at high risk for breast cancer for 4 weeks at the maximum tolerated dose (MTD) as determined during the dose escalation group phase to assess bexarotene concentration in the breast tissue. (Dose Expansion Group)

SECONDARY OBJECTIVES:

I. To detect bexarotene concentration in the serum at baseline and at 4 weeks of treatment.

II. To detect bexarotene concentration in the breast tissue at 4 weeks of treatment in the dose escalation group.

III. To investigate the effects of topical bexarotene on serum biomarkers. IV. To investigate the biologic effects of topical bexarotene 1% gel in the breast tissue, we will determine the change from baseline in i) lipid biomarkers (total cholesterol, triglycerides, low density lipoprotein [LDL], high density lipoprotein [HDL]), ii) thyroid function biomarkers (thyroid stimulating hormone [TSH], T4, T3), iii) calcium.

TERTIARY OBJECTIVES:

I. To examine changes in gene expression associated with retinoid action. (Dose Expansion Group)

OUTLINE: This is a dose-escalation study.

Group 1 will apply 10mg bexarotene topically to one breast every other day (QOD) for 4 weeks; Group 2 will apply 10mg bexarotene topically to one breast every other day (QOD) for 1 week and then daily for 3 weeks after confirmation that toxicity is at an acceptable range; Group 3 will apply 10mg bexarotene topically to one breast every other day (QOD) for 1 week, then daily for 1 week, and then 20mg daily for 2 weeks after confirmation that toxicity is at an acceptable range.

After completion of study treatment, patients are followed up at 30 days.

Primary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: Up to 30 days after completion of study drug ]
    Will be assessed by Common Terminology Criteria for Adverse Events criteria.


Secondary Outcome Measures :
  1. Changes in markers of systemic toxicity [ Time Frame: Baseline up to 28 days ]
    Serum biomarkers to be tested will be total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, thyroid-stimulating hormone, T4, T3, and calcium. Will be summarized using mean, standard deviation and median (range) for continuous variables at each time point. Wilcoxon rank-sum test may be used to examine the difference of continuous variables between participants' characteristics groups. Will be plotted as functions of time (baseline, week 1, week 2, and week 4). Linear mixed effect model will be applied to model the biomarker change over time for all participants. Appropriate transformation and regression model will be used to ensure the model fit.

  2. Bexarotene concentration [ Time Frame: Up to 30 days after completion of study drug ]
    Will be determined using liquid chromatography-mass spectrometry (MS)/MS. Will be summarized using mean, standard deviation and median (range) for continuous variables at each time point. Wilcoxon rank-sum test may be used to examine the difference of continuous variables between participants' characteristics groups. Will be plotted as functions of time (baseline, week 1, week 2, and week 4). Linear mixed effect model will be applied to model the biomarker change over time for all participants. Appropriate transformation and regression model will be used to ensure the model fit. Will be calculated along with a 95% confidence interval.

  3. Tissue markers [ Time Frame: Up to 28 days ]
    One of the four cores collected from the core biopsies from baseline (in dose expansion cohort only) and post treatment (all dose expansion cohort participants and optional for dose escalation group) will be formalin-fixed and paraffin embedded (FFPE) for histological analysis. One of the four cores collected from the core biopsies from baseline and post treatment will be placed in RNALater and utilized for gene expression of ribonucleic acid (RNA) biomarkers. Gene expression will be performed.
