What this trial studies

This early phase I trial investigates the effects of topical and oral minoxidil on hair loss caused by endocrine therapy in women with stage I-IV breast cancer. The study aims to evaluate the safety and tolerability of low-dose oral minoxidil and to gather preliminary data on its effectiveness compared to topical minoxidil. Participants will be randomized into two groups: one applying minoxidil foam topically and the other receiving it orally, both for up to 12 months. The trial focuses on improving quality of life by addressing the distressing side effect of hair loss during cancer treatment.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with a diagnosis of breast cancer stages I-IV who are currently on endocrine therapy and experiencing hair loss.

Not a fit: Patients who are pregnant, nursing, or have a history of certain types of alopecia or prior use of minoxidil may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide an effective treatment option for hair loss in breast cancer patients undergoing endocrine therapy, potentially improving their quality of life.

How similar studies have performed: While the use of minoxidil for hair loss is established, this specific application in breast cancer patients undergoing endocrine therapy is novel and has not been extensively tested.
