About
The purpose of this study was to assess the magnitude and duration of pain relief of a single IA injection of 2 doses (16 and 32 mg) of FX006, an extended-release formulation of TCA, relative to normal saline (placebo control).
Full description
This was a double-blind, randomized, parallel group, dose-ranging, single-dose study. The study was conducted in male and female patients ≥40 years of age with OA of the knee.
Approximately 300 patients with OA of the knee were randomized, using a centralized randomization procedure, to 1 of 3 treatment groups (1:1:1) and treated with a single IA injection of:
16 mg FX006, 32 mg FX006, or normal saline (placebo).
Each patient was evaluated for a total of 24 weeks following a single IA injection. Following screening, safety and efficacy were evaluated at 7 out-patient visits (Days 1 [Baseline], Weeks 4, 8, 12, 16, 20, and 24).
The study was expected to enroll over approximately 6 to 7 months.
