Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a two-phase multicenter, double-blind, randomized, prospective evaluation of intra-articular injection(s) comparing APS to intra-articular HA injection(s). The maximum study duration for each subject will be 50 months; 48 months from treatment to last follow-up, and two additional months if the maximum visit window is realized. A total of 246 patients will be enrolled. These patients will meet specific inclusion and exclusion criteria, but can be generally characterized as patients with painful unilateral knee OA who have been unable to achieve satisfactory pain relief with previous conservative OA treatment.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

During the long-term follow-up phase (12 - 48 months), subjects may also elect to cross over to the other treatment arm and receive additional injections of the other treatment as frequently as needed, provided they did not experience any significant clinical concerns after previous treatment administrations and are benefiting from it, as determined by the investigator. Subjects may only cross over from their originally assigned treatment group to the other treatment group one time during the study.

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
This is a double-blind study where subjects and evaluators are blinded to treatment up to 12-months. During the long-term follow-up phase (12 - 48 months), only subjects will be blinded to the study treatment resulting in single-blind design following 12-month follow-up time point.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

nSTRIDE APS

The nSTRIDE APS Kit is designed to be used for the safe and rapid preparation of APS from a small sample of blood at the patient's point of care. The APS is to be injected intra-articularly for the treatment of knee osteoarthritis and associated symptoms.
