Brief Summary:
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 62 months; 60 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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 246 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description: During the long-term follow-up phase (12 - 60 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.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: 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 - 60 months), only subjects will be blinded to the study treatment resulting in single-blind design following 12-month follow-up time point.
Primary Purpose: Treatment
Official Title: A Two-Phase, Multicenter, Randomized Study Comparing Autologous Protein Solution With Hyaluronic Acid Intra Articular Injections in Patients With Knee Osteoarthritis
Actual Study Start Date : July 14, 2017
Estimated Primary Completion Date : September 30, 2019
Estimated Study Completion Date : September 30, 2023

Arm Intervention/treatment
Active Comparator: 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.
Intra-articular injection
Other Name: Autologous Protein Solution

Active Comparator: Synvisc-One
Synvisc-One is only intended for intra-articular use by a physician to treat pain associated with osteoarthritis of the knee
Device: Synvisc-One
Intra-articular injection
Other Name: hylan G-F 20
