Brief Summary:
This is a multi-center, randomized, double-blind, parallel group, placebo controlled trial to evaluate the contribution of Triamcinolone Hexacetonide (TH) to pain relief, both in terms of magnitude and duration, when used within a single injection of Cingal® compared to a single injection of TH in subjects with OA of the knee.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: Cingal Drug: Cingal
A chemically cross-linked sodium hyaluronate supplied as a 4-mL unit dose with a nominal 18 mg of triamcinolone hexacetonide (TH)

Active Comparator: Triamcinolone Hexacetonide (TH) - Lederlon Drug: Triamcinolone Hexacetonide - Lederlon

Placebo Comparator: Placebo Drug: Placebo
0.9% Saline

Primary Outcome Measures :
  1. Change in baseline WOMAC (Western Ontario and McMaster Universities Arthritis Index) pain score [ Time Frame: 26 Weeks ]
    The change from Baseline in knee pain as measured by the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) Pain Score (Range 0 mm No Pain to 100 mm Worst Pain) at 26 weeks post treatment comparing the Cingal® arm to the TH arm, the Cingal arm to the Placebo arm, and the TH arm to the Placebo arm.

  4. 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:

    • 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
  8. Subject is willing to maintain a stable dose of oral glucosamine and/or chondroitin sulfate products throughout the study, if taken prior to signing ICF.
  9. Subject is able to understand and comply with the requirements of the study and voluntarily provides consent.

Baseline Inclusion Criteria 24 Subject has a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain-sub-score ≥ 50 mm and ≤ 90 mm in the affected knee and ≤ 30 mm in the contralateral knee on a 100 mm Visual Analog Scale (VAS) scale.

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.
  2. Subject had an arthroscopy of either knee within 3 months of signing the ICF.
  3. Subject had an open surgical procedure of either knee or hip or any surgery of the spine within 12 months of signing ICF. Subject plans to have knee, hip or spine surgery within the study period.
  4. Subject has intra-articular trauma to the Index knee. Subject has concurrent multi-system or multi-limb trauma.
  5. Subject has evidence or medical history of the following diseases in the Index knee: septic arthritis; inflammatory joint disease; history of Reiter's syndrome; gout; chondrocalcinosis associated with recurrent episodes of acute synovitis of the knee consistent with pseudogout; osteochondritis dissecans, Paget disease of the bone; ochronosis; acromegaly; hemochromatosis; primary osteochondromatosis; known history of Wilson disease; heritable disorders or collagen gene mutations.
  6. Subject has a history of cartilage repair surgery in the Index knee within 3 years of signing the ICF.
  7. Subject has a history of Anterior cruciate ligament (ACL) repair, reconstruction or injury in the Index knee within 3 years of signing the ICF.

  23. Subject previously treated with Cingal for knee osteoarthritis.

Baseline Exclusion Criteria 25. Subject has a decrease of ≥ 20 mm in the WOMAC pain-sub-score (average of 5 pain scales) from Screening to Baseline in the Index knee on a 100 mm Visual Analog Scale (VAS) scale.

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).

28. Subject has range of motion of less than 100° flexion in either knee.
