An Open-Label Pilot Intervention Trial to Prevent Diabetes in Prediabetic Adult Survivors of Childhood Cancer

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a first-in survivor, single-arm pilot study with the goal of establishing evidence of feasibility and safety of a combined pharmacologic (metformin) and lifestyle intervention (using an existing digital platform) to prevent diabetes in prediabetic adult survivors of childhood cancer. Primary Objective The primary aim of this proposal is to establish the feasibility and safety of a 24-week combined metformin + intensive lifestyle intervention among adult survivors with prediabetes (including a 12-week lifestyle alone run-in followed by 12-week combined intervention among survivors remaining prediabetic). Primary endpoints of this trial will be adherence to 1) daily metformin administration and 2) completion of required core-curriculum of the lifestyle change intervention. Safety will be assessed using the Global Rating of Side Effects Burden Secondary Objectives The secondary aim is to assess preliminary evidence for efficacy of the combined metformin + intensive lifestyle intervention on glycemic control and insulin resistance. Glycemic control will be measured by fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) and insulin resistance measured by the homeostatic model assessment (HOMA-IR) and IGF- binding protein 1 (IGF-BP1; a measure of insulin sensitivity strongly correlated with euglycemic insulin clamp testing). Exploratory Objectives To assess preliminary evidence for efficacy of the combined metformin + intensive lifestyle intervention on weight, other anthropometric measures, blood pressure and lipid profile, physical activity (self-reported and as measured by accelerometer), frailty measures, and health-related quality of life (HRQOL). We will also assess diabetes development at future SJLIFE visits. To assess measures of participation in the lifestyle change program as well as barriers to participation and medication adherence.

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.

Ages Eligible for Study:18 Years to 44 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT
Inclusion CriteriaExclusion Criteria
  1. * Investigators will recruit to enroll 55 survivors who are at least 18 but \<45 years of age who participate in the St. Jude Lifetime Cohort Study (SJLIFE) and have been identified to have prediabetes defined as hemoglobin A1c (HbA1c)
  2. * Participant in SJLIFE
  3. * ≥18 and \<45 years of age
  4. * Prediabetic: fasting plasma glucose 105-125 mg/dL, hemoglobin A1c 5.7- 6.4% (either or both criteria may be present) According to institutional and NIH policy, the study will accession research participants regardless of sex and ethnic background. Institutional experience confirms broad representation in this regard.
  1. * Absence of treatment related diabetes risk. Survivors will be excluded if their cancer treatment required observation only, surgery alone not involving the abdomen or brain, radiation alone not involving the chest (pancreatic risk), abdomen or brain (e.g. retinoblastoma treated with enucleation alone, melanoma of an extremity treated with excision alone, neuroblastoma in an infant requiring observation only)
  2. * Diabetes at baseline assessment: FPG ≥126 mg/dL, HbA1c ≥6.5% or previous diagnosis by a physician (except gestational diabetes that resolved post-partum)
  3. * BMI \<19 kg/m2
  4. * Current metformin use (including for any period ≥30 days in the past 1yr)
  5. * Known allergy to metformin
  6. * Current use of other oral glucose lowering medications, non-insulin injectable diabetes medications or insulin (Appendix)
  7. * Current participation in a lifestyle change program
  8. * Chronic kidney disease ≥ stage IIIb (eGFR \< 45 mL/min)
  9. * Severe cardiovascular disease or recent intervention (NYHA class ≥2 or heart failure hospitalization in the past 6mo, Aortic stenosis, Heart block including LBBB or 3rd degree AV block, SBP \>180 or DBP \>105 mmHg, myocardial infarction or coronary revascularization in the past 1 month)
  10. * Severe hepatic dysfunction: cirrhosis or AST/ALT \>3 times upper limit of normal
  11. * Pulmonary disease with dependence on oxygen or daily use of bronchodilators
  12. * Weight loss \>10% in the past 6 months
  13. * Bariatric surgery in the past 2 years
  14. * Pregnant, within 3 months post-partum, nursing, or planning to become pregnant
  15. * Anemia: hematocrit \<36% in males or \<33% in females
  16. * Ongoing alcohol or substance abuse using criteria from the AUDIT and DAST questionnaires (Appendix)
  17. * Diagnosis of schizophrenia or other psychotic disorder
  18. * Vision impairment limiting ability to interface with the digital program
  19. * Unable to swallow medication
  20. * Non-English speaking
  21. * Cognitive impairment defined by IQ \<80
  22. * Current active cancer or undergoing treatment for active cancer
