An Open-Label Pilot Intervention Trial to Prevent Diabetes in Prediabetic Adult Survivors of Childhood Cancer
NCT04742751 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04742751
The ClinicalTrials.gov registry entry for NCT04742751 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 96 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is St. Jude Children's Research Hospital, which has 441 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with PreDiabetes appearing as the primary indexed condition, and to 2 interventions — of which Metformin is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04742751 reports 1 study location spanning 1 distinct geographic area — top geographies include Tennessee. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
