Summary

The purpose of this study is to compare the efficacy of celecoxib versus placebo in delaying the onset of pain and improving walking function in subjects with knee Osteoarthritis

Clinical Details

Official title: A Double-Blind, Placebo-Controlled, Randomized, Crossover Pilot Study of the Efficacy of Celecoxib 200 mg QD in Relieving Pain and Walking Dysfunction in Osteoarthritis of the Knee.

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Supportive Care

Primary outcome: The primary endpoint is the time to onset of moderate and severe pain. The mean change in time to onset of moderate and sever pain between the first and second walks will be compared using paired t-tests.

Secondary outcome: Secondary endpoints are the distance to onset of moderate to sever pain the the percent responders in each group. Thirty subjects will be studied in this randomized, placebo-controlled, double-blind crossover study.

Detailed description: We have developed a walking model that safely and reproducibly induces pain in subjects with knee OA in a manner that permits the comparison of the effect of different therapies on pain control. In a previous study, we demonstrated that a self-paced 20 minute walk followed by a one-hour rest and a second coordinator-paced 20-minute walk was well tolerated and generated moderate to severe pain in all participants within the time frame of the walk. We will now use this model, but with a crossover design to test the efficacy of celecoxib compared to placebo for the control of knee pain and improvement of walking function.

Eligibility

Minimum age: 45 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- If female and of childbearing potential, must be using adequate contraception since

last menses and will use adequate contraception during the study,

- Diagnosed as having OA of the knee

- Functional Capacity Classification of I-II (FCC)

- If on active analgesic or anti-inflammatory pain medication, must have VAS pain

score>=30mm in signal knee related to walking on a flat surface within the previous 48 hours. Subjects who are not taking any pain medication must have a VAS pain score>=40mm in the signal knee

- At baseline visit, must have a history of pain in the signal knee>=40mm when walking

on the flat within the previous 48 hours.

- In the Investigator's opinion, the patient requires and is eligible for therapy with

an anti-inflammatory analgesic.

- If on an NSAID or analgesic, patient must have completed a washout period prior to

baseline assessments that is a minium of five half lives.

- The patient has provided written informed consent before undergoing any study

procedures. Exclusion Criteria:

- Diagnosed as having inflammatory arthritis or acute trauma at the index joint.

- Another painful condition that would interfere with his/her ability to walk or to

make reasonable assessments of their pain.

- Received an injection of corticosteroid into the signal knee within 3 months; or with

a hyaluronan produce in the signal knee within the previous 6 months.

- Requires the use of a cane or other assistive device to complete the walk.

- Known cardiovascular disease which has been symptomatic in the past 12 months

- History of blood clots or is at any increased risk for blood clotting.

- Asthma or any breathing condition which would preclude walking briskly for 20

consecutive minutes or 40 minutes total.

- Has taken any NSAIDs, COX-2 inhibitors, or any analgesic, with the exception of the

rescue acetaminophen, within two days prior to Visit 2

- Active malignancies or any type or a malignancy that has recurred within 5 years

before enrollment.

- Diagnosed as having or has been treated for esophageal, gastric, pyloric channel,

duodenal ulceration within 90 days

- Active GI disease, a chronic or acute renal or hepatic disorder, or a significant

coagulation defect.

- Any chronic illness or laboratory abnormalities considered to be clinically

significant.

- Received any investigational medication within 30 days

- Known hypersensitivity to celecoxib, NSAIDs, to sulfonamides

- Use of the following drugs:

1. NSAIDs or COX-2 specific inhibitors 2. Analgesics except rescue medication within 24 hours of a study visit 3. Anticoagulants 4. Lithium 5. Glucosamine or chondroitin sulfate are excluded unless on stable dose for at least 3 months
