General Information



Disease Group:	Cancer Prevention Head And Neck	Supported By:	N/A

Phase of Study:	Phase II	Return Visit:	Participants will visit the clinic at Baseline, Week 6 and Week 12.

Treatment Agents:	Rosiglitazone	Home Care:	One Avandia 8 mg tablet by mouth once daily for 12 weeks. Medication may be taken at any time of the day.

Treatment Loc:	Independent Multicenter Arrangements

Estimated Length of Stay in Houston:	N/A


Description/ Intervention:	The goal of this clinical research study is to learn if rosiglitazone (Avandia™) can help to control leukoplakia and erythroplakia and help to prevent them from becoming oral cancer. The safety of this drug will also be studied.

Study Objectives / Outcomes

Primary Objective:

•

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

Secondary Objectives:

• 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.

• As DNA ploidy is the leading molecular predictor of progression to cancer, 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.

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

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

Enrollment Eligibility

If you do not meet the enrollment eligibility, there may be other treatment options for you. Please Contact the Referral Office for more information.

Inclusion Criteria:

1) 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 wks. 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.

2) (Cont') * Patients will be registered using a two-stage registration process. The first stage of registration will be completed on the day of informed consent. The second stage of registration will be completed once the biopsy has been histologically confirmed to contain dysplasia.

3) The subject is >/= 18 years of age. Because no dosing or adverse event data are currently available on the use of rosiglitazone in participants <18 years of age, children are excluded from this study but will be eligible for future pediatric trials, if applicable.

4) The subject's life expectancy is > 12 weeks and Karnofsky performance score is 70-100%.

5) The subject meets the following laboratory eligibility criteria during a time not to exceed 4 weeks prior to going on study: Hemoglobin and hematocrit levels above the lower limit of normal. White blood cells >/= 3,000/mL, Platelets >/= 125,000/mL, 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

6) 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.

7) 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.

8) The subject is willing and able to fully participate for the duration of the study.

9) If applicable, the subject has been counseled on smoking cessation

10) The effects of Avandia on the developing human fetus @ the recommended therapeutic dose are unk. For this reason,& b/c Avandia has been associated w/ fetal death & growth retardation in rats & rabbits & 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 & 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 & will be removed from the trial.

11) Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

1) The subject has active cancer or carcinoma in situ of the head and neck

2) The subject has a contraindication to biopsy

3) The subject is of New York Heart Association (NYHA) Class I to IV heart failure, as well as, any patients with known heart failure.

4) The subject has a history of myocardial infarction, angina, or coronary artery disease within the past 6 months, or active cardiac disease.

5) The subject exhibits clinical evidence of active liver disease, history of chronic liver disease or edema.

6) The subject is a diabetic not on treatment or hyperglycemic (has a random blood glucose level >200 mg/dl). 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.

7) The subject is currently receiving medical therapy for dysregulated blood sugar.

8) The subject has experienced jaundice with Rezulin� (troglitazone)

9) The subject has known hypersensitivity to Rosiglitazone, Avandia, or any of its components

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

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

12) The subject has had chemotherapy, immunotherapy, hormonal therapy (other than HRT for menopause), or radiation therapy within 18 months of the Baseline visit.

13) The subject will need concurrent chemotherapy, radiotherapy, hormonal (other than HRT for menopause), or immunotherapy during the time of study.

14) The subject has received any investigational medication within 30 days of the Baseline visit or is scheduled to receive an investigational drug during the course of the study.
