The Effect of Intra-articular Bilateral Knee Injections of Zilretta on Performance Measures in Adults With Knee OA

Knee Osteoarthritis Clinical Trial

Official title:
The Effect of Intra-articular Bilateral Knee Injections of Zilretta on Osteoarthritis Research Society International (OARSI) Recommended Physical Performance Measures in Adults With Knee Osteoarthritis

Clinical Trial Summary

This study will be an open-label trial to determine the functional effects of bilateral IA injections of Zilretta into knee joints of 70 subjects with bilateral KL grade 2-4 symptomatic knee osteoarthritis (OA). Measurement and evaluation of outcomes at baseline, 6, 12 and 24 weeks will allow assessment of short and long-term effects, consistent with Osteoarthritis Research Society International (OARSI) and Outcome Measures in Rheumatology (OMERACT) recommendations.

Clinical Trial Description

The primary aim of the proposed study is to demonstrate the effect of IA injection of Zilretta on physical performance measures in adults with bilateral knee OA. The primary study endpoint will be the change in OARSI recommended physical performance tests (30-second chair standing test, 40m fast-paced walking test, stair ascent) 12 weeks after treatment. The secondary outcome will be the change in Knee Injury and Osteoarthritis Outcome Score (KOOS-PS) patient-reported physical function short form. The tertiary outcomes will be the change in KOOS-Quality of life subscale (QoL) and Numerical Rating Scale (NRS) for pain. All outcomes will be assessed at 6- and 24-week follow-up as well to define the course and trajectory of effects. Specific Aim 1: To determine the extent to which intra-articular (IA) injection of Zilretta in patients with bilateral knee OA improves physical performance (OARSI recommended physical performance measures). Primary Hypothesis 1: Bilateral knee intra-articular injection of Zilretta results in improved physical performance detectable at 6 weeks, 12 weeks (primary), and 24 weeks. Specific Aim 2: To determine the extent to which IA injection of Zilretta in patients with bilateral knee OA improves physical function (KOOS-PF). Hypothesis 2: Bilateral knee IA injection of Zilretta results in improved patient-reported physical function (KOOS-PS) at 6 weeks,12 weeks (primary), and 24 weeks. Specific Aim 3: To determine the extent to which bilateral knee IA injection of Zilretta in patients with bilateral knee OA improves quality of life (KOOS-QoL). Hypothesis 3: Intra-articular (IA) bilateral knee injection of Zilretta in patients with bilateral knee osteoarthritis results in improved quality of life (KOOS-QoL) detectable at 6 weeks, 12 weeks (primary), and 24 weeks. ;
