Arms	Assigned Interventions
A: Placebo Comparator placebo	Other: placebo
B: Active Comparator celecoxib 200 mg qd p.o.	Drug: celecoxib
C: Experimental TDS-943 40 mg bid topically	Drug: TDS-943 (topical diclofenac sodium 4% spray)

Detailed Description:

This is a multicenter, outpatient, multiple-dose, placebo- and active controlled, double-blind, double-dummy parallel group, randomized (stratified by unilateral vs. bilateral knee OA) trial. The trial will enroll subjects who have been diagnosed with OA of the knee (confirmed by weight-bearing x-ray) and whose condition is in flare at baseline. Subjects who qualify to enter the study will be randomized to topical TDS-943 40 mg bid, oral celecoxib 200 mg qd, or placebo in a 3:2:2 ratio.
