Study Summary

This phase IIa trial studies how well metformin hydrochloride works in preventing oral cancer in patients with an oral premalignant lesion (oral leukoplakia or erythroplakia). Oral premalignant lesions look like red or whitish plaques or lesions in the mouth that do not rub off and can be associated with a higher risk of cancer. Metformin hydrochloride may help prevent oral cancer from forming in patients with an oral premalignant lesion.

Primary Outcome

Number of participants with complete and partial clinical response to metformin intervention. Criteria for complete and partial clinical response are: Complete Response (CR): Disappearance of all evidence of lesion(s). Partial Response (PR): Greater than or equal to 50% reduction in the sum of the products of diameters of lesion(s) measurable at baseline. Non-measurable lesion(s) may not increase greater than or equal to 25% in size and no new lesion may appear.
