Effects of Mediterranean Diet and Naltrexone/Bupropion Treatment in Obese Breast Cancer Patients

August 28, 2018 updated by: Ji-Won Lee, Gangnam Severance Hospital

Effects of Mediterranean Diet and Naltrexone/Bupropion Treatment on Body Weight and Metabolic Risk Factors in Obese Breast Cancer Patients After Breast Cancer Treatment

Obesity among breast cancer survivors is known to be associated with recurrence and other co-morbidities. However, there have been no studies on weight reduction program combining diet and anti-obesity drug for obese breast cancer survivors. The purpose of this randomized clinical trial is to examine the effects of Mediterranean Diet and naltrexone/bupropion treatment on inflammation and metabolic risk factors in overweight or obese breast cancer patients after breast cancer treatment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

20 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers
