NCT02637323

Brief Summary

The objectives of this study were to characterize the local extent and duration of exposure of TA from FX006 and TCA IR, characterize the systemic PK of FX006 and TCA IR, and assess the safety and general tolerability of a single 5 mL IA injection of 32 mg FX006 relative to 40 mg of TCA IR in patients with OA of the knee.

Outcome Measures

Primary Outcomes (1)

  • Synovial Fluid Drug Concentrations (pg/mL) by Time Point Pooled Across FX006 Cohorts and TCA IR in Synovial Fluid

    All baseline (pre-treatment) values and all post-baseline values recorded as below LLOQ (\<50 pg/mL) were set to zero. Geometric mean summary statistics were computed on adjusted concentration values. One (1) was added to each concentration value observed. BLQ values for the computation of geometric mean are included in the summary with a value of 1 (0+1).

    Up to 20 Weeks

Secondary Outcomes (1)

  • Plasma Drug Concentrations (pg/mL) by Time Pooled Across FX006 Cohorts and TCA IR 40 mg Cohort

    Up to 20 Weeks

Other Outcomes (1)

  • Plasma Pharmacokinetic Parameters for FX006 and TCA IR

    Up to 20 Weeks

Study Arms (2)

FX006 32 mg

EXPERIMENTAL

Drug: FX006 32 mg

TCA IR 40 mg

ACTIVE COMPARATOR

Commercially available triamcinolone acetonide, single 1 mL intra-articular (IA) injection Immediate-release formulation

Drug: TCA IR 40

Interventions

Also known as: Zilretta
FX006 32 mg

Single 1 mL IA injection

Also known as: Kenalog®-40 Injection, Triamcinolone Acetonide Crystalline Suspension (TAcs)

Limitations and Caveats

Subsequent to completion of clinical studies extensive testing was performed to assess the actual FX006 dose delivered. It was determined that the FX006 delivered dose to the patient from an FX006 40 mg vial is 32 mg.
