Metformin for the Prevention of Oral Cancer in Patients With Oral Leukoplakia or Erythroplakia
NCT05237960 · View on ClinicalTrials.gov ↗
Study Summary
This phase IIb trial tests whether metformin works in preventing oral cancer in patients with oral leukoplakia (white patches) or erythroplakia (red patches). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount of glucose (sugar) in the blood. It decreases the amount of glucose patients absorb from food and the amount of glucose made by the liver. Metformin also increases the body's response to insulin, a natural substance that controls the amount of glucose in the blood. This trial may help researchers determine if metformin can stop changes in the mouth that are related to pre-cancer growths in the mouth.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05237960
The ClinicalTrials.gov registry entry for NCT05237960 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 34 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Arizona, which has 379 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 Oral Leukoplakia appearing as the primary indexed condition, and to 4 interventions — of which Biospecimen Collection 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: NCT05237960 reports 10 study locations spanning 10 distinct geographic areas — top geographies include Arizona, California, Florida. 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.
