Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Disease Response
A response is the number of participants whose tumor demonstrated a decrease in FDG uptake (SUV) by 50% or greater in at least one of the metastatic sites as measured by PET imaging at the end of 4 weeks of treatment compared to baseline.
Week 4
Secondary Outcomes (1)
Median Time to Event
From Baseline to 1 Year
Study Arms (1)
Naltrexone
EXPERIMENTALNaltrexone 50 mg will be taken orally once a day every day of a 28 day treatment course (cycle 1) and continue for another identical 28 day treatment (cycle 2) . PET scan will be performed after cycle 1 and cycle 2 complete.
Interventions
Naltrexone 50 mg will be orally taken once daily for 28 day (cycle 1), and continues once daily for another 28 days (cycle 2) without interval.
Patients will receive PET scan approximately one hour after being injected with 2-Deoxy-2-\[18F\]fluoro-D-Glucose (FDG). PET scans will be performed after the completion of cycle 1 and cycle 2 and during the 1 year follow-up.
Eligibility Criteria
You may qualify if:
- Metastatic, hormone-receptor positive breast cancer
- Disease that has progressed despite previous systemic hormonal therapy. Hormone therapy must be terminated at least 2 weeks prior to study enrollment.
- Prior chemotherapy, immunotherapy, or biological therapy is allowed if at least 3 weeks since last treatment. Patient must recover from the acute toxic effects of the treatment prior to study enrollment.
- Measurable disease as defined by solid tumor response (RECIST) criteria or non-measurable bone disease that is Positron-emission tomography (PET) avid
- Karnofsky performance status \>70%
- Female, age 18 years or older
- Adequate organ function within 14 days of study enrollment including the following:
- Adequate bone marrow reserve: absolute neutrophil (segmented and bands) count (ANC) ≥ 1.5 x 10\^9/L, platelets \>75 x 10\^9/L, and hemoglobin \> 8 g/dL
- Hepatic: bilirubin ≤ 2 times the upper limit of normal (× ULN), aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2 × ULN. (AST and ALT ≤ 5 × ULN is acceptable if liver has tumor involvement)
- Renal: creatinine ≤ 2 times the upper limit of normal
- Women of childbearing potential are required to use an effective method of contraception (ie, a hormonal contraceptive, intrauterine device, diaphragm with spermicide, condom with spermicide, or abstinence) during the study and for 3 months after the last dose of study drug.
- Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
You may not qualify if:
- Brain metastases unless stable for 1 month or more following radiation therapy.
- Pregnant or lactating women. PET-CT is not approved during pregnancy. A negative urine or serum pregnancy test is required for all females of child bearing potential within 7 days prior to study entry. Pregnancy testing is not required for post-menopausal or surgically sterilized women.
- Use of any short-acting or long-acting opioid medication (including morphine, meperidine, oxycodone, hydromorphone, hydrocodone, fentanyl, tramadol) within 10 days prior to study enrollment
- Pain uncontrolled with the use of non-narcotic drugs (acetaminophen or non-steroidal medications)
- History of sensitivity to naltrexone
- Acute hepatitis or liver failure
- Immunosuppressive therapy for patients with autoimmune diseases, organ transplant, or other indications
