Clinical Trial Summary

The purpose of this study was to evaluate the safety, efficacy and pharmacokinetics of FX006 in patients with osteoarthritis of the knee.

Description:

Study FX006-2011-001 was a multi-center, randomized, double-blind, active comparator, parallel-group, single-dose study designed to assess the magnitude and duration of pain relief of three doses (10, 40, and 60 mg) of FX006, an extended-release formulation of TCA, relative to commercially-available TCA IR.

The general tolerability of a single injection of FX006 also was assessed.

Secondary objectives included exploration of the effect of FX006 on functional improvement, responder status, time to onset of pain relief, global impressions of change, and consumption of analgesic medications and evaluation of the PK profile of single injection of the three dose levels of FX006.

The study was planned to be conducted in up to 224 male and female patients ≥40 years of age with OA of the knee enrolled at 22 study centers in the US, Australia, and Canada.

Primary	Change From Baseline to Week 10 in Weekly Mean of the Average Daily (24-hour) Pain Intensity Score for FX006 60 mg vs TCA IR 40 mg	The pain intensity score is measured using an 11-point numeric rating scale (NRS), where 0 indicates "no pain" and 10 indicates "pain as bad as you can imagine."	10 weeks
Primary	Change From Baseline to Week 12 in Weekly Mean of the Average Daily (24-hour) Pain Intensity Score for FX006 60 mg vs TCA IR 40 mg	The pain intensity score is measured using an 11-point numeric rating scale (NRS), where 0 indicates "no pain" and 10 indicates "pain as bad as you can imagine."	12 weeks
Secondary	Change From Baseline to Each of Weeks 8, 10, and 12 in Weekly Mean of the Average Daily (24-hour) Pain Intensity Score for FX006 10mg and 40 mg vs TCA IR 40 mg	The pain intensity score is measured using an 11-point numeric rating scale (NRS), where 0 indicates "no pain" and 10 indicates "pain as bad as you can imagine."	Weeks 8, 10 and 12
Secondary	Change From Baseline to Each of Weeks 1, 2, 3, 4, 5, 6, 7, 9, and 11 in Weekly Mean of the Average Daily (24-hour) Pain Intensity Score.	The pain intensity score is measured using an 11-point numeric rating scale (NRS), where 0 indicates "no pain" and 10 indicates "pain as bad as you can imagine."	Weeks 1-7 and Week 9 and 11
Secondary	WOMAC A (Pain Subscale) Change From Baseline at Week 8	The Western Ontario and McMaster Universities (WOMAC®) Osteoarthritis Index is a questionnaire that measures pain, stiffness, and function both independently and collectively, using a Likert 3.1, 5-point scale. The Likert Scale uses the following descriptors for all items: none, mild moderate, severe, and extreme, corresponding to an ordinal scale of 0-4. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.	8 weeks
