About this study

Official title: A Pilot Multi-Center International Double-Blind Placebo Controlled Randomized Study of Sulindac, a Pan-Cox Inhibitor, in Oral Premalignant Lesions

The purpose of this study is to see if a drug called sulindac can prevent the development of changes in the mouth that are related to oral pre-cancer growths (oral epithelial dysplasia) or oral cancer. Sulindac is an anti-inflammatory drug that has already been tested in people with arthritis (inflammation of a joint).

This study is being done by Memorial Sloan-Kettering Cancer Center in New York, Amrita Institute of Medical Sciences and Research Center in Cochin, India, and Regional Cancer Centre (RCC) in Trivandrum, India.

Read the detailed description

Oral precancerous lesions (OPL) represent a valuable model for clinical trials for tobacco related cancers. However, due to the relatively low prevalence of this condition in the United States, subject accrual to such trials is slow. Conversely, in India, the prevalence of oral leukoplakia is among the highest in the world. Indeed oral cancer, caused by exposure to tobacco smoke, alcohol and betel nut quid, is the leading cause of cancer deaths in India.

To date, there are no effective treatments documented in randomized controlled clinical trials to prevent malignant transformation of leukoplakia. However, evidence that non-steroidal anti-inflammatory drugs (NSAIDs) prevent experimental and animal head and neck cancer, and colon and breast cancer in humans lends support to the promise of NSAIDs in the chemoprevention of oral cancer.

The purpose of this protocol is to pilot a multi-center chemoprevention trial of sulindac, a pan-cyclooxygenase (COX) inhibitor, for oral leukoplakia through an international collaboration between Memorial Sloan-Kettering Cancer Center (MSKCC), New York, Regional Cancer Centre (RCC) in Trivandrum, India and the Amrita Institute of Medical Sciences (AIMS), Kerala, India. Specifically, we will conduct a 66 subject, 2-arm, double-blind, placebo-controlled randomized study of sulindac 150 mg bid to test the clinical efficacy, safety and molecular effects of sulindac against OPL and OPL tissue. Oral leukoplakia subjects will be enrolled from both RCC, AIMS and MSKCC, however, we expect that most subjects will be recruited from AIMS due to the substantially higher prevalence of this condition among the Indian compared to the US population.

MSKCC will be the coordinating center for this trial, and will thus be responsible for all aspects of clinical trial design and management. Our study team, in collaboration with the Office of Clinical Research and the Office of the Physician-in-Chief, has spent a considerable amount of time and effort in developing a comprehensive data and safety monitoring (DSM) plan.

  2. To Evaluate the Correlation Between Baseline COX-2 Expression or DNA Ploidy With Clinical Response or Biomarker Modulation

    Measured: baseline and after 24 weeks

  3. To Evaluate the Safety of Chronic Dosing of Sulindac in This Subject Population

Where is the study taking place?

The record lists 3 sites in India, United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

- To Evaluate the Efficacy of Sulindac in Subjects With Early or Advanced Oral Premalignant Lesion (OPL) by Both Clinical Response (Reduction in Size of All Lesions) and Histological Response (Change in Histological Grade). (time frame: after 24 weeks of study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
