Summary

Naltrexone is a drug which blocks some effects of chemicals called beta-endorphins that are made in the body. Beta-endorphins can be made in response to stress, injury, and also pleasurable activities. In previous studies, it has been shown that levels of beta-endorphins in the blood go up during radiation therapy, and that this increase is linked to fatigue. This suggests that naltrexone may help to reduce fatigue in people who are getting radiation therapy In this research study, the investigators are looking to see whether naltrexone works better than a placebo in reducing fatigue during radiation therapy.

Detailed description

This trial has two phases (a monitoring and an intervention phase). Monitoring Phase: Prior to starting radiotherapy for non-metastatic breast cancer, participants will be approached and consented for the monitoring phase of the study, which involves longitudinal monitoring of fatigue in order to establish whether a patient develops fatigue after starting radiation. The level of pre-radiotherapy fatigue will be obtained during the final two weeks before radiotherapy is started. All participants will undergo weekly monitoring of fatigue via a brief self-report questionnaire. The monitoring period will continue up until one month after the conclusion of radiotherapy. Those whose fatigue symptoms increase above the pre-specified threshold at any point during the monitoring period will be approached about enrollment into the intervention phase of the study. Intervention Phase: This is a randomized, double-blind, parallel-arm 5-week clinical trial which will be used to determine the effect of naltrexone on fatigue emerging during radiation therapy for non-metastatic breast cancer.
