Inclusion Criteria
The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- Subject has been taking an NSAID at least 15 of the past 30 days for index knee pain

- Grades 2 or 3 OA as defined by the Kellgren and Lawrence Grading System of the medial tibiofemoral joint (joint space narrowing in the medial compartment > lateral compartment as assessed by x-ray) using the Altman Atlas of OA7. This must be documented with a report from an x-ray of the study joint taken either at screening or within 1 year prior to screening

Exclusion Criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details


- Subject has a documented history of an allergic reaction (hives, rash, etc.) or a
clinically significant intolerance to celecoxib, sulfonamides, aspirin, or opioids
including oxycodone


- Significant pain outside the index knee, including significant hip or back pain that
can not be distinguished from OA pain or that interferes with ability to walk.
(Patients with bilateral knee OA will be allowed into the study. The index knee should
be defined as the more painful knee


- Predominantly patellofemoral knee osteoarthritis in the index knee as assessed by
clinical examination


- Subject who are unable to discontinue all formulations of prior analgesics other than
acetaminophen during the Washout Period of the study, or who are anticipated to be
unable to discontinue rescue medication for 24 hours prior to the respective visits.
(Low dose aspirin may be taken for cardiac prophylaxis


- Excessive signal knee joint laxity indicative of functional ligamentous deficiency

Brief Title  ICMJE Measuring Gait And Self-Reported Pain In Patients With Osteoarthritis Of The Knee Using Placebo/Oxycodone/Celecoxib.
Official Title  ICMJE Measures Of Gait And Self-Reported Pain In Patients With Osteoarthritis Of The Knee: A Randomized, Single-Blind Washout, Double-Blind Treatment, Double Dummy Cross-Over Pilot Trial Using Placebo, Oxycodone And Celecoxib (A9011030)
Brief Summary The Purpose of this trial is to evaluate the use of a cross-over trial design in an osteoarthritis population. We will determine the inter- and intra-subject variability in osteoarthritis (OA) endpoints and evaluate if efficacy can be detected by measuring OA endpoints following treatment with 2 different types of analgesics in a crossover study of this design.
Detailed Description Methodology study to evaluate the use of a cross over design and gait analysis. The study was terminated by mutual consent with the study site at a meeting on the 1 April 2009, because of slow recruitment due to a high screen fail rate. The study was not stopped for safety reasons.
