Naltrexone RCT for Treatment-Emergent Fatigue in Patients Receiving Radiation Therapy for Breast Cancer

November 12, 2021 updated by: Fremonta Meyer, MD, Dana-Farber Cancer Institute

Naltrexone Randomized Controlled Trial for Treatment-Emergent Fatigue in Patients Receiving Radiation Therapy for Breast Cancer

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria

Eligibility Criteria for Monitoring Phase

  • Age ≥ 18
  • Diagnosis of: invasive breast cancer (stage I-III), ductal carcinoma in situ, lobular carcinoma in situ, lobular carcinoma
  • Plan to receive radiation therapy

Eligibility Criteria for Randomization Phase

  • Participants may have had prior breast surgery and/or chemotherapy.

  • Age ≥18 years.

    --Because no dosing or adverse event data are currently available on the use of naltrexone in cancer patients <18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.

  • Participants must have acceptable pre-treatment laboratory values as defined below:

    • total bilirubin within normal institutional limits
    • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
    • creatinine within normal institutional limits OR
    • creatinine clearance ≥60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
    • If child-bearing potential, willingness to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent document
  • Receiving radiation therapy of any type at DFCI, BWH, or MGH (including but not limited to partial breast irradiation, two-field, three-field, and four-field plans)
  • FACIT-F subscale score >=10 pre-radiation therapy and decrease in FACIT-F of 10 points or more as compared to pre-radiotherapy baseline

Exclusion Criteria:

Exclusion Criteria for Monitoring Phase

  • Suicidal ideation, as determined via PHQ-9
  • Non-English speaking

Exclusion Criteria for Randomization Phase

  • Participants with major depressive disorder and/or suicidal ideation as determined by PHQ-9.
  • Participants who are receiving any other investigational agents that might interact with study medication or influence the measurement of study outcomes.
  • Participants with known metastatic disease should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to naltrexone.
  • Participants who have used opioid-containing medications (including cough/cold medications containing codeine and/or antidiarrheals containing loperamide) in the past 2 weeks, or who are expected to require opioid-containing medications within the duration of the treatment period.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Pregnant women are excluded from this study because naltrexone is category C agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with naltrexone, breastfeeding should be discontinued if the mother is treated with naltrexone.
  • Participants using other contraindicated medications (thioridazine, yohimbine)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in FACIT-fatigue Subscale Score From Randomization to End of Study
Time Frame: Evaluated at baseline, weekly monitoring visits from start of radiation therapy and meets fatigue eligibility threshold
Functional Assessment of Chronic Illness Therapy-Fatigue Subscale (FACIT-fatigue subscale): This 13-item self-report scale measuring fatigue and functional impairment as a result of fatigue has been validated in cancer patients (Cella et al. Cancer 2002;94:528-38) The scale is reverse-scored and the range is 0 (maximum fatigue) - 52 (minimum fatigue). According to ICD10 criteria, a score <= 34 indicates significant cancer related fatigue. A change of 10 points has been shown to constitute a clinically meaningful difference on this subscale.
Evaluated at baseline, weekly monitoring visits from start of radiation therapy and meets fatigue eligibility threshold
