Further study details as provided by Pfizer:

Primary Outcome Measures:
  • To evaluate the efficacy of celecoxib in subjects with Early or Advanced oral premalignant lesion (OPL)
  • by both clinical response (reduction in size of all lesions,
  • prevention of growth in the index lesion and of any new lesions)
  • and histological response (change in histological grade).
  • To evaluate the safety of chronic multiple dosing of celecoxib in this patient population.

Secondary Outcome Measures:
  • To evaluate the treatment effects in modulating the expression of genomic and proliferative markers after 12 weeks of treatment with study drug, followed by 12 weeks off study drug.

Estimated Enrollment: 42
Study Start Date: November 2000
