Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 231 participants

Brief Summary

This is a multi-center, randomized, double-blind, parallel group, placebo controlled trial to compare the safety and effectiveness of a single injection of Cingal® to a single injection of Triamcinolone Hexacetonide (TH) to achieve pain relief and other symptoms of osteoarthritis of the knee.

Detailed Description

To determine the contribution of Triamcinolone Hexacetonide (TH) when combined with sodium hyaluronate for pain relief, both in terms of magnitude and duration, when used as single injection, as compared to a single injection of TH alone in subjects diagnosed with osteoarthritis of the knee.

A saline placebo is included within the trial to set the expectation of a return to Baseline pain for the subjects.

Subject has had at least two signs and at least two symptoms of OA disease (based on the European League Against Rheumatism (EULAR) recommendations for diagnosing knee OA) in the Index knee for at least 6 months despite conservative treatment (weight reduction, physical therapy, pain medications, etc.). The EULAR signs and symptoms are as follows:

• Signs: crepitus, restricted movement and bony enlargement
• Symptoms: persistent knee pain, limited morning stiffness and reduced function

5. Subject must be willing to abstain from other IA treatments of the knee for the duration of the study.

6. Subject is willing to discontinue all analgesics including nonsteroidal anti-inflammatory drugs (NSAIDs), except acetaminophen before the treatment injection and through the completion of the study. NSAIDs should be discontinued through the Screening period.

7. Subject is willing to use only acetaminophen (up to a maximum of 3.0 grams per day) for the treatment of joint pain for the duration of the study. At least forty-eight hours prior to the Baseline Visit and each follow-up visit, the Subject is willing to discontinue use of acetaminophen

9. Subject is able to understand and comply with the requirements of the study and voluntarily provides consent.

Exclusion Criteria

1. Subject received an IA injection of Hyaluronic Acid (HA) and/or steroid in either knee within 6 months of signing the ICF. A Subject will be excluded if they are planning to receive an HA or steroid injection (other than the study injection) in either knee during the course of this study.

19. Subject has any contraindication to the receipt of a corticosteroid.

20. Subject is receiving or in litigation for worker's compensation.

23. Subject previously treated with Cingal for knee osteoarthritis.

26. Subject has a synovial fluid aspirate volume > 10 mL in the Index knee. 27. Subject has a contraindication to continue with the study treatment injection based on the visual appearance of the synovial fluid aspirate unless the fluid is examined microscopically prior to injection with no clinically significant findings (e.g. bacteria, crystals or blood).
