Clinical Trial Summary

The goal of this clinical research study is to learn how Actos (pioglitazone) may affect oral premalignant lesions (OPLs) and/or the risk of mouth cancer. The safety of this drug will also be studied.


Description:

PRIMARY OBJECTIVES:

I. To determine the clinical and histologic response of oral premalignant lesions to 24 weeks of therapy with pioglitazone, 45 mg qd, defined as 50% or greater reduction in the sum of all measured products of perpendicular dimensions of target lesions, or improvement in the degree of dysplasia or hyperplasia.

SECONDARY OBJECTIVES:

I. To determine the degree of change of putative biomarkers of pioglitazone efficacy including (but not restricted to) and in order of priority, tissue levels of:

- PPAR gamma,

- cyclin D1 and p21 as indirect measures of pharmacological effect

- TUNEL for apoptosis and Ki-67 for proliferation

- transglutaminase and involucrin as markers of squamous differentiation

- 15-PGDH, loss of heterozygosity (LOH). II. To determine the degree of change of C-reactive protein (CRP) in plasma. III. To assess tobacco and alcohol use among trial participants and to examine the relationship of tobacco and alcohol use to treatment response.

IV. To assess the safety of this agent in this population.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive pioglitazone hydrochloride orally (PO) once daily (QD) for 24 weeks.

ARM II: Patients receive placebo PO QD for 24 weeks.

After completion of study treatment, patients are followed up for 2 weeks.

- If a participant has had a biopsy of the target OPL lesion(s) within 6 weeks prior to the screening visit and archival tissue is available and the participant agrees to have archival tissue used for histologic confirmation and biomarker analysis, then NO additional biopsies (of the OPL) need to be performed at the screening visit; the pre-screening biopsy must undergo centralized pathology review before the second stage of registration can be performed; if archival tissue is not available, a waiting period of 6 weeks from the time of the last biopsy must be observed before re-biopsy for study purposes

- If a participant has not had a biopsy of the suspected OPL at the time of the screening visit, then a biopsy of the lesion must be performed during the screening visit; the screening biopsy must undergo centralized pathology review before the second stage of registration can be performed

- Dorsal, lateral or ventral tongue

- Floor of mouth

- An ADVANCED premalignant lesion defined as the presence of at least one of the following:

- Participants using the drugs listed below may not be randomized unless they are willing to stop the medications (and possibly change to alternative non-excluded medications to treat the same conditions) no less than 3 days prior to starting pioglitazone or placebo on this study; the use of the following drugs or drug classes is prohibited during pioglitazone/placebo treatment: participants taking inhibitors of CYP2C8 (gemfibrozil, ketoconazole, quercetin, trimethoprim), enzyme inducers of CYP2C8 (cortisol, dexamethasone, phenobarbital, rifampin), and CYP3A4 substrate

Exclusion Criteria:

- The participant has active cancer or carcinoma in situ of the head and neck

- The participant has a contraindication to biopsy

- The participant has presence of congestive heart failure (New York Heart Association (NYHA) class II-IV), uncontrolled hypertension (systolic > 150 or diastolic > 100), or unstable angina

- The participant has any history of congestive heart failure or history of myocardial infarction within the past 6 months

- The participant exhibits clinical evidence of active liver disease or history of chronic liver disease

- The participant has > CTCAE grade 1 edema

- The participant has known diabetes and is on insulin or oral agents; the participant is receiving medical therapy for dysregulated blood sugar

- The participant who currently receives an enzyme inhibitor of CYP2C8 (gemfibrozil, ketoconazole, quercetin, trimethoprim), or enzyme inducer of CYP2C8 (cortisol, dexamethasone, phenobarbital, rifampin), or CYP3A4 substrate will not be eligible for randomization after assessing eligibility in stage two unless he/she will not be eligible for randomization after assessing eligibility in stage two unless he/she is willing to stop these drugs and possibly replace them with alternative therapies

- The participant currently receives pregabalin or thioridazine

- The participant has experienced jaundice with Rezulin (troglitazone)

- The participant has a history of colorectal cancer, familial adenomatous polyposis (FAP) or hereditary non-polyposis colorectal cancer (HNPCC)

- The participant has a history of bladder cancer or in situ bladder cancer

- The participant has a history of invasive cancer within the past 18 months (excluding non-melanoma skin cancer and in situ cervical cancer); participants (excluding those with a history of colorectal cancer, FAP, HNPCC, bladder cancer or in situ bladder cancer) who received curative treatment and have shown no evidence of recurrence for 18 months will be eligible
