Detailed Description:

This will be a randomized, double-blind, placebo-controlled, parallel-group study in which patients with knee OA will be randomized to either CF101 1 mg or matching placebo tablets every 12 hours and followed for 12 weeks on treatment. For patients with bilateral knee involvement, only 1 knee will be selected for evaluation, namely, the most severely involved knee that meets study criteria (the "index knee"). Screening examinations will occur within 1 month prior to dosing. Washout of non-specific non-steroidal anti-inflammatory drugs (nsNSAIDs) and cyclo-oxygenase-2 (COX-2) inhibitors will occur prior to dosing, and must be followed by requalification before dosing. Disease activity will be assessed using changes from baseline in Patient's Global Assessment (PGA) and Investigator's Global Assessment (IGA) scores, and the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index and subscales for pain, physical function, stiffness, according to the Outcome Measures in Rheumatology Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) criteria. Assessments will take place at Screening, Baseline (Week 0), and at Weeks 2, 4, 8, 12, and 14.

  • Negative screening serum pregnancy test for female patients of childbearing potential
  • Females of childbearing potential must utilize, throughout the course of the trial, 2 methods of contraception deemed adequate by the Investigator (for example, oral contraceptive pills plus a barrier method)
  • All aspects of the protocol explained and written informed consent obtained

Exclusion Criteria:

  • Predominant patellofemoral disease
  • Concomitant local or systemic inflammatory arthropathy which could confound evaluation of the knee
  • Ipsilateral hip or extremity disease which could confound evaluation of the knee

  • Use of chondroitin sulfate and/or glucosamine, or diacerin, within 2 weeks prior to the screening visit
  • Concomitant requirement for NSAID, coxib medication, or opioid analgesics (acetaminophen is allowed)
  • Use of systemic corticosteroids >10 mg/d of prednisone, or equivalent
  • Presence or history of uncontrolled arterial hypertension or symptomatic hypotension
  • Significant cardiac arrhythmia or conduction block, congestive heart failure, or any other evidence of clinically significant heart disease; other clinically significant findings on screening electrocardiogram (ECG)
  • Hemoglobin level <10.0 gm/dL at the screening visit
  • White blood cell count <3000/mm3 at the screening visit
  • Platelet count <125,000/mm3 at the screening visit
