Study summary

This clinical trial identifies the needs and preferences of rural stage I-III postmenopausal breast and endometrial cancer survivors and evaluates the impact of an adaptive, online program, mobile (m)Health + ecological momentary assessment (EMA) intervention, on lifestyle modification and their weight loss efforts. Obesity, a condition marked by an abnormally high, unhealthy amount of body fat, is associated with lower physical and psychological well-being, higher risk of recurrence, and higher cancer-specific and all-cause mortality (number of deaths). Lifestyle factors, such as low physical activity and unhealthy diet, are the main contributors to obesity that are modifiable. Lifestyle weight loss programs focusing on modifiable factors can improve cancer-specific survival and many aspects of health, but access to these programs can be challenging in rural settings. A remote lifestyle program, adapted to individual goals and needs, may help promote healthy behaviors, improve cancer outcomes, and reduce disease burden in stage I-III postmenopausal breast and endometrial cancer survivors.

Read the detailed description

PRIMARY OBJECTIVES:

I. To determine the feasibility of an mHealth + EMA intervention in addition to the web-based lifestyle program with remote outcome assessments among rural breast and endometrial cancer survivors. (Aim 1) Ia. To identify rural cancer survivors' perspectives and unique needs/challenges of participating in a web-based lifestyle program via focus groups pre- and post-intervention (n=20); (Aim 1a) Ib. To determine the feasibility of mHealth + EMA among early non-responders (week 5-26); (Aim 1b) Ic. To determine the feasibility of remote outcome assessments. (Aim 1c) II. To determine the preliminary efficacy of the additional mHealth + EMA intervention for early non-responders from the web-based lifestyle program (within-person change from week 5-26). (Aim 2)

EXPLORATORY OBJECTIVE:

I. To explore the differences in metabolomic, inflammatory, behavioral, and psychosocial factors between early responders and early non-responders at baseline, month 1 and month 6.

OUTLINE:

PHASE I (WEEKS 1-4): Patients complete self-paced web-based lifestyle program modules over 45-90 minutes weekly for 4 weeks. Patients adhere to a personalized diet meeting American Institute of Cancer Research (AICR) guidelines and receive access to online resources, including AICR resources, online cooking class videos, healthy eating recipes and tips. Patients participate in moderate-intensity aerobic physical activity over 10-30 minutes on 5 days weekly and resistance training over 30 minutes on 2-3 times weekly.

PHASE II (WEEKS 5-26): Patients are assigned to 1 of 2 groups based on Phase I progress.

GROUP I (EARLY RESPONDER): Patients continue web-based program modules, exercise program and diet recommendations as in Phase I. Patients also attend virtual group sessions over 45-50 minutes weekly for weeks 5-26.

GROUP II (EARLY NON-RESPONDER): Patients continue web-based program modules, exercise program and diet recommendations as in Phase I. Patients also set goals for behavioral changes weekly and receive just-in-time adaptive interventions (JITAI) tailored resource components via mHealth + EMA during weeks 5-26. Patients wear a physical activity tracker daily and receive access to the Fitbit application (App).

Patients may also participate in a focus group over 30-45 minutes on study. Additionally, patients undergo urine and blood sample collection throughout the study.

After completion of study intervention, patients may follow up in 6 months.

Inclusion criteria

  • (BMI) ≥ 25kg/m\^2
  • Age: 40-69 years
  • 1-5 years post-diagnosis of stage I-III breast cancer or stage I-III endometrial cancer
  • No known evidence of recurrence (local or distant) or second, primary cancer
  • No prior history of new other since their breast or endometrial cancer diagnosis (other than non-melanoma skin cancer)
  • Not currently participating in any weight loss programs, no personal trainer, and not meeting the physical activity guidelines

Exclusion criteria

Exclusion Criteria:

  • Severe medical conditions, such as unstable cardiovascular disease or digestive disorders, that would preclude physical activity and dietary intervention
  • Lack of physician clearance if determined necessary by the Physical Activity Readiness Questionnaire (PAR-Q+)
  • Acute physical limitations for unsupervised exercises at home
  • Unable to give
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Preferences, needs and satisfaction (Aim 1a)

    Focus groups will be audio recorded through online videoconference (e.g. Teams) and transcribed using NVivo. Content analysis will be conducted to identify patterns, themes, and perspectives from participants using NVivo coding or similar software. When possible, the frequency, intensity, and context of certain perspectives will be described. Similarly, thematic analysis will be conducted using NVivo to identify themes (e.g., likes/dislikes, motivations, expectations) and mapped to potential intervention components.

    Time frame: At pre- and post-intervention, assessed up to week 26

  2. Percentage of early non-responders who complete the mobile Health + ecological momentary assessment intervention (Aim 1b)

    Will report the frequency, proportion, and 95% confidence intervals (CIs) of early non-responders who completed the intervention.

    Time frame: Up to week 26

  3. Percentage of all participants who complete all assessments (Aim 1c)

    Will report the frequency, proportion, and 95% CIs of all participants who completed outcome assessments.

    Time frame: Up to week 26

  4. Changes in weight (Aim 2)

    Linear mixed models will be used to account for repeated measures, with random effects for the individual. The linear mixed models will use all available data under a missing-at-random assumption and will assess potential attrition bias by comparing baseline/week 4 characteristics of completers versus non-completers, with sensitivity analyses is missingness appears outcome-related. Will report the preliminary effect size as within-person changes on weight (from week 4 to week 26).

    Time frame: At baseline (T0), at week 4 (T1), and at week 26 (T2)

  5. Changes in muscle mass (Aim 2)

    Will estimate the preliminary effect size using linear mixed models.

    Time frame: At baseline (T0), at week 4 (T1), and at week 26 (T2)

  6. Changes in metabolic profiles (Aim 2)

    Will estimate the preliminary effect size using linear mixed models.

    Time frame: At baseline (T0), at week 4 (T1), and at week 26 (T2)

  7. Changes in inflammatory markers (Aim 2)

    Will estimate the preliminary effect size using linear mixed models.

    Time frame: At baseline (T0), at week 4 (T1), and at week 26 (T2)

  8. Changes in behaviors (Aim 2)

    Will estimate the preliminary effect size using linear mixed models.

    Time frame: At baseline (T0), at week 4 (T1), and at week 26 (T2)
