Exclusion criteria

Exclusion criteria: Patients fulfilling at least one of the following criteria may not be included in the study: Disease-related criteria 1. Any condition that could possibly confound the patient’s assessment of index knee pain in judgment of the investigator (i.e., ipsilateral hip OA, gout, radicular low back pain and hip pain that is referred to the knee that could cause misclassification, pain in any other area of the lower extremities or back that is equal to or greater than the index knee pain) 2.

Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to assess the magnitude and duration of pain relief of a single intra-articular (IA) injection of FX006, an extended release formulation of triamcinolone acetonide (TCA), relative to normal saline (placebo control).;Secondary Objective: - To assess the effect of FX006 on the magnitude and duration of pain relief relative to triamcinolone acetonide injectable suspension, immediate release (commercially available) (TCA IR). - To assess the effect of FX006 on function, responder status, global impressions of change, stiffness, and consumption of analgesic medications relative to both controls. - To assess the safety and general tolerability of a single IA injection of FX006 relative to both controls.;Primary end point(s): Efficacy Average daily (24-h) pain intensity score on a 0 to 10 NRS scale with 0 indicating ‘no pain’ and 10 indicating ‘pain as bad as you can imagine’ (Dworkin et al¸ 2005; Cleeland and Ryan, 1994);Timepoint(s) of evaluation of this end point: The study will involve a Screening period (up to 21 days) and 7 out-patient visits (Days 1 [Baseline], Week 4, Week 8, Week 12, Week 16, Week 20 and Week 24). Each patient will be evaluated for a total of 24 weeks after treatment. Patients will be evaluated for efficacy and safety.

Secondary

MeasureTime frame
Secondary end point(s): Efficacy Worst daily pain intensity score on a 0 to 10 NRS scale with 0 indicating ‘no pain’ and 10 indicating ‘pain as bad as you can imagine’ (Dworkin et al¸ 2005) • WOMAC? Osteoarthritis Index (LK 3.1, 5-point scale): pain, stiffness and function domains independently and collectively (Bellamy et al, 1988). • PGIC: 7-point scale (Farrar et al, 2001; Guy, 1976; Dworkin et al, 2005) (Appendix 3). • CGIC: 7-point scale (Guy, 1976) (Appendix 3). • KOOS Quality of Life (QOL) Subscale (http://www.koos.nu/) • SF-12 (1 week recall version) (http://www.sf-36.org/tools/sf12.shtml) • Responder status as defined by: o Proportion of patients experiencing either >50%, >30% or >20% decrease (improvement) in pain from baseline in weekly mean of the average daily (24-hr) pain intensity scores (substantial, at least moderate and minimum clinically important difference, respectively, as defined by Dworkin et al, 2008) o Outcome Measures in Rheumatology (OMERACT) - Osteoarthritis Research Society International (OARSI) criteria (Pham, 2004) • Time of onset of pain relief (based on average daily pain intensity scores) • Consumption of rescue medication Safety • AEs • Physical examinations • Index knee examinations • Index knee X-rays • Vital signs • ECGs • Clinical laboratory evaluations;Timepoint(s) of evaluation of this end point: The study will involve a Screening period (up to 21 days) and 7 out-patient visits (Days 1 [Baseline], Week 4, Week 8, Week 12, Week 16, Week 20 and Week 24). Each patient will be evaluated for a total of 24 weeks after treatment. Patients will be evaluated for efficacy and safety.
