About this trial

This is a Phase IIa oral cavity leukoplakia study of pioglitazone 15mg and metformin 500mg BID for 12 weeks. The primary objective is to determine the clinical and histologic changes of leukoplakia from baseline following a 12 week course of twice daily pioglitazone-metformin. Outcomes are defined as are a reduction of the leukoplakia grade in \> 50% of treated participants and a partial or complete clinical response defined as 50% or greater reduction in the sum of measured targeted lesions. In addition, participants who show clinical and histologic improvement should correlate with a significant reduction of Ki-67 proliferative indices in lesions of these participants as compared to baseline.

Eligibility criteria

Qualifiers

Biopsy proven hyperplasia in high risk anatomic areas (floor of mouth, mobile tongue, oropharynx). Hyperplasia or dysplasia of any grade in any erythroplakia lesion. Mild, moderate or severe dysplasia within the lesion at any site of the oral cavity or oropharynx.

Must have objective evidence of oral leukoplakia that is measurable in 2 dimensions per RECIST. The lesion(s) may be clinically characterized by leukoplakia, erythroplakia, erythro/leukoplakia. Lesions may be located in the oral cavity or oropharynx. However, the index lesion must be located in an anatomic site accessible by punch biopsy and be a minimum of 4mm x 8 mm to permit a 4mm punch biopsy.

Age 18 years or older at the time of consent.

Evidence of adequate organ function within 14 days prior to Day 1

Disqualifiers

Participant is taking another investigational agent (not approved by the FDA for any indication).

A history of allergic reactions attributed to compounds of similar chemical or biologic composition to ACTOplus Met, pioglitazone or metformin.
