Rosiglitazone Maleate in Treating Patients With Oral Leukoplakia

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00369174
Recruitment Status : Completed
First Posted : August 29, 2006

Brief Summary:
This phase II trial is studying how well rosiglitazone works in preventing oral cancer in patients with oral leukoplakia. Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of rosiglitazone may keep cancer from forming in patients with oral leukoplakia

Condition or disease Intervention/treatment Phase
Oral Leukoplakia Drug: rosiglitazone maleate Other: laboratory biomarker analysis Phase 2

Detailed Description:


I. To determine the rate of clinical response of oral premalignant lesions (OPL) to 12 weeks of therapy with rosiglitazone (Avandia), 8 mg daily, defined as greater than or equal to 50% reduction in the measured product of perpendicular dimension of the target lesion, or improvement in the degree of dysplasia.


I. To determine the rate and degree of change of putative biomarkers of rosiglitazone efficacy including:

COX-2, cyclin D1, Ki-67, p21/waf1, PPAR gamma, K1 cytokeratin, involucrin, transglutaminase expressions, and TUNEL.

II. To estimate the correlation between DNA ploidy measurements in OPL with clinical response and or response of biomarkers to rosiglitazone therapy, and to estimate the efficacy of rosiglitazone therapy to normalize aberrant DNA ploidy in OPL.

III. To thoroughly assess smoking patterns among trial participants and to examine the relationship of smoking to treatment response.

IV. To assess the safety of this agent in short-term use in this population.

OUTLINE: This is a multicenter, open-label, nonrandomized study.

Patients receive oral rosiglitazone once daily. Treatment continues for 12 weeks in the absence of unacceptable toxicity.

After completion of study treatment, patients are followed at 1 week.

Primary Outcome Measures :
  1. Proportion of subjects who show complete or partial response in either clinical or histological outcomes [ Time Frame: 12 weeks ]
    Estimated together with 95% confidence interval. The confidence interval will be constructed using exact binomial confidence intervals (rather than the normal approximation).

Secondary Outcome Measures :
  1. Tissue expressions of COX-2, cyclin D1, Ki-67, p21/waf1, PPAR gamma, K1 cytokeratin, involucrin, and transglutaminase, and tissues levels of apoptosis (assessed using TUNEL) [ Time Frame: 12 weeks ]
    Summarized at each time point using summary statistics such as the mean, median, and range. The changes in levels of these biomarkers will also be explored with similar summary statistics and with graphical methods as well.

  2. Tissue DNA ploidy [ Time Frame: 12 weeks ]
  3. Smoking and alcohol use [ Time Frame: Up to 12 weeks ]
    Assessed descriptively. Fisher's exact test may be used to assess whether there is a significant association between smoking status and efficacy of rosiglitazone.

  4. Adverse events defined as any untoward medical occurrence in a study participant, graded using the NCI CTCAE version 3.0 [ Time Frame: Up to 12 weeks ]
    Descriptively summarized in tabular form.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males or females with a suspected or histologically confirmed index oral premalignant lesion (excluding carcinoma in situ), 12mm or greater in size that has not been biopsied in the past 6 weeks; each index lesion must be either a:

    • dysplastic measurable leukoplakia or erythroplakia in the oral cavity or accessible oropharynx, or
    • hyperplastic leukoplakia of high-risk sites, lateral and ventral tongue and floor of mouth
  • The subject's life expectancy is > 12 weeks and Karnofsky performance score is 70-100%
  • Hemoglobin and hematocrit levels above the lower limit of normal
  • White blood cells >= 3,000/uL
  • Platelets >= 125,000/uL
  • Total bilirubin =< 1.5 x ULN
  • AST (SGOT)/ALT (SGPT) =< 1.5 x ULN
  • BUN and serum creatinine =< 1.5 x ULN
  • LDH =< 1.5 x ULN
  • If the subject is female and of childbearing potential (women are considered not of childbearing potential if they are at least two years postmenopausal and/or surgically sterile), she:

    • has been using adequate contraception (abstinence, IUD, birth control pills, or spermicidal gel with diaphragm or condom) since her last menses and will use adequate contraception during the study, AND
    • is not lactating, AND
    • has a documented negative serum pregnancy test within 14 days prior to randomization
  • The subject has discontinued any other oral cancer chemopreventive therapy at least 12 weeks prior to the Baseline visit and all toxicities have been fully resolved; daily aspirin is permitted
  • The subject is willing and able to fully participate for the duration of the study
  • If applicable, the subject has been counseled on smoking cessation
  • The effects of rosiglitazone (Avandia) on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, and because rosiglitazone has been associated with fetal death and growth retardation in rats and rabbits and placental pathology in rats, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately and will be removed from the trial

  • The subject exhibits clinical evidence of active liver disease, history of chronic liver disease or edema
  • The subject currently receives insulin, sulfonylurea or metformin (doses of rosiglitazone greater than 4 mg daily in combination with these therapies are not currently indicated; because this protocol uses the maximum recommended dose of 8 mg daily, subjects on insulin, sulfonylurea or metformin will be ineligible for participation in this trial); the subject is currently receiving thiazolidinediones; the subject is a diabetic not on treatment or hyperglycemic (has a random blood glucose level > 200 mg/dl); the subject has diabetic macular edema
