About this trial
This early phase I trial studies the possible benefits and/or side effects of topical or oral minoxidil in treating endocrine therapy-induced hair loss (alopecia) in patients with stage I-IV breast cancer. Endocrine therapy-induced alopecia (EIA) is a distressing side effect that leads to reduced quality of life and early cessation of therapy in women undergoing treatment for breast cancer. Patients on endocrine therapy commonly report hair loss or thinning. Minoxidil is a drug that may promote hair growth and reduce hair loss. Oral minoxidil may increase hair density in women with EIA, and work the same as topical minoxidil in treating EIA in patients with breast cancer.

Trial outcomes
Primary outcomes
Proportion of days assigned medication was taken/applied
For the oral minoxidil group, the proportion of pills taken will be reported with a 95% confidence interval. For the topical minoxidil group, the proportions of days medication was applied will be reported with a 95% confidence interval.
Secondary outcomes
Occurrence of at least one adverse event (AE) of grade 1 or higher
Adverse events will be summarized using National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 with reporting of the number and percentage of patients affected. The total number of participants with AEs of any grade, and the total number of participants with grade 3 or higher AEs will be compared between randomized groups using Fisher's exact test.
Change in hair density
At least mild-to-moderate improvement in hair density from baseline to 3 months as determined by a board-certified dermatologist from photographs. Will construct two-sided 95% confidence intervals for improvements from baseline and differences between randomized groups. Response will be dichotomized as no improvement versus moderate-to-significant improvement.
Change in hair density
At least mild-to-moderate improvement in hair density from baseline to 6 months as determined by a board-certified dermatologist from photographs. Will construct two-sided 95% confidence intervals for improvements from baseline and differences between randomized groups. Response will be dichotomized as no improvement versus moderate-to-significant improvement.
Change in hair density
At least mild-to-moderate improvement in hair density from baseline to 12 months as determined by a board-certified dermatologist from photographs. Will construct two-sided 95% confidence intervals for improvements from baseline and differences between randomized groups. Response will be dichotomized as no improvement versus moderate-to-significant improvement.
