Official title

Phase II Study of Naltrexone for the Treatment of Hormone-Refractory, Metastatic Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

RATIONALE: Estrogen can cause the growth of breast cancer cells. Naltrexone may fight breast cancer by blocking the use of estrogen by the tumor cells. Naltrexone may also stop the growth of breast cancer by impairing blood flow to the tumor. PURPOSE: This phase II trial is studying how well naltrexone works in treating women with metastatic breast cancer that is no longer responsive to previous hormone therapy.
