iMETX (Individualized Metabolic RX): a Pilot Study

February 14, 2020 updated by: Kathy Miller, Indiana University

iMETX (Individualized Metabolic RX): a Pilot Study of an Environmental Intervention to Increase Energy Expenditure Among Breast Cancer Survivors

The purpose of this study is to test the mechanics and feasibility of delivering an individualized intervention to increase physical activity in breast cancer survivors.

In this study, researchers will test an intervention that uses a commonly worn activity monitor (i.e., global positioning system [GPS] enabled running watch) to see if they can "prescribe" specific ways to increase physical activity that are individually tailored to each participant. The goal is to help participants increase their daily physical activity without having to join a gym or other traditional fitness program. Researchers want to see if they can make specific recommendations (using an application that can be added to a cell phone, tablet and/or computer) on ways participants can slowly increase their activity based upon where they live and work and in a way that is tailored individually to them. For example, participants may be given a route to walk on their lunch break, or new place to park to allow for a longer walk to their job. The goal is to meet participants where they are in their current level of fitness, and to help them think of new and creative ways of increasing activity without the frustration of soreness or risk of injury. As they move more, the recommendations will increase with them.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Objectives The investigators hypothesize that developing an individualized and dynamic exercise intervention (iMETX) that accounts for factors of the built environment will be feasible for breast cancer patients following primary treatment. This pilot study will assess the feasibility and provide preliminary estimates of effectiveness of the environmental intervention for increasing the energy expenditure and energetic capacity of breast cancer patients. The investigators will also explore patient feedback with this intervention and changes in levels of fatigue and quality of life. Experience and data from this initial pilot study will be used to refine the intervention and design subsequent studies to test its effectiveness.

Primary objective Evaluate the feasibility of an individualized, dynamic, environmental physical activity intervention for early stage breast cancer patients following primary treatment.

Secondary objectives

  1. Determine a preliminary estimate of effect size of the environmental intervention on energetic capacity (power envelope) as measured by Power Protocol-B
  2. Determine a preliminary estimate of effect size of the environmental intervention on average daily EE as measured by a wearable hybrid GPS/accelerometer physical activity monitor
  3. Determine the effect of the environment intervention on the physical parameters of BMI and lean body mass
  4. Determine the effect of the environmental intervention on patient reported fatigue and quality of life
  5. Determine the persistence of changes in average daily EE after the intervention is complete (i.e., when individual movement tasks are no longer suggested).
  6. Obtain formal and informal patient feedback throughout and after the intervention to assess satisfaction and perceptions of feasibility
  7. Assess safety

Exploratory objectives Blood samples will be collected prior to and following the intervention and banked for future correlative studies, including the following: inflammatory cytokines (high sensitivity C reactive protein and interleukin 6), adipokines (adiponectin and leptin), sex hormones (estradiol, estrone, testosterone, and sex hormone binding globulin), and telomere length. In addition the invstigators will explore correlations of built and social environment characteristics and psychosocial characteristics with pre-intervention and changes in energy expenditure.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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.
Experimental: iMETX intervention
Individualized exercise recommendation
Behavioral: iMETX intervention

Pre-intervention the participants will wear the running watch for 3 weeks so that researchers can collect data about their daily routines regarding where and how much energy they expend.

During the intervention participants will wear the running watch for 12 weeks. Every 1-3 days the participants will be given an individualized recommendation for how to increase their activity via the iMETX application. Participants will be able to provide feedback to the researchers throughout intervention period regarding what works and does not in terms of the recommendations for increasing activity.

Post-intervention the participants will wear the running watch for 12 weeks so that researchers can collect data in order to determine whether physical activity changes made during the intervention are sustained.
