Clinical Trial Summary

This study is being conducted to evaluate the efficacy and safety of ASA compared to placebo in the management of osteoarthritis (OA) symptoms of the knee.

Description:

This is a prospective, multicenter, randomized, double-blind, placebo-controlled Phase 3 study of ASA in patients with OA of the knee. Initially, 474 subjects are planned for inclusion in this study using a group sequential design with an interim analyses and a final analysis. Patients will be randomly assigned in a 1:1 ratio to receive a single intra-articular (IA) injection of 2 mL of ASA (plus 2 mL of normal saline) or 4 mL of normal saline on Day 1.

They will have serial assessments of knee pain, function, and symptoms scores, as well as safety assessments for up to 52 weeks after administration of the study drug.

• Knee effusion requiring aspiration of the index or contralateral knee within 3 months prior to screening.

• Contralateral knee pain above limits defined in the protocol

• Current therapy with any immunosuppressive therapy or medical conditions likely to require systemic steroids during the study.

• Any active or systemic infection including infection of the index knee joint or breakdown or disease of the index knee skin/soft tissues.

• Clinically significant intercurrent illness, medical condition, non-knee pain, or medical history that would jeopardize patient safety, limit participation, or compromise interpretation of data derived from the patient

• Active alcohol or substance use disorder, or any other reason that would make it unlikely that the patient will comply with study procedures

• Females who are pregnant or lactating

• Participation in another clinical trial within the 30 days (or 5 half-lives of the investigational compound, whichever is longer) before screening.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The difference in change from baseline in WOMAC Pain scale at 6 months between ASA- and placebo-treated patients	The WOMAC is widely used in the evaluation of hip and knee OA. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: pain, stiffness, and physical function. The WOMAC measure has been used in clinical trials to evaluate the efficacy of surgical treatments, medicinal and biological products, devices, and physical therapies.	Baseline to Week 26
Secondary	The difference between changes from baseline for ASA- and placebo- treated patients in WOMAC Function at 6 months	The WOMAC is widely used in the evaluation of hip and knee OA. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: pain, stiffness, and physical function. The WOMAC measure has been used in clinical trials to evaluate the efficacy of surgical treatments, medicinal and biological products, devices, and physical therapies.	Baseline to Week 26
Secondary	The difference between changes from baseline for ASA- and placebo-treated patients in the OMERACT-OARSI responder rate at 6 months	The OMERACT-OARSI core domain set for clinical trials in hip and/or knee osteoarthritis responder criteria will be used to assess whether a patient is a responder or not.	Baseline to Week 26
Secondary	The difference between changes from baseline for ASA- and placebo-treated patients in WOMAC Pain at 3 months	The WOMAC is widely used in the evaluation of hip and knee OA. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: pain, stiffness, and physical function. The WOMAC measure has been used in clinical trials to evaluate the efficacy of surgical treatments, medicinal and biological products, devices, and physical therapies.	Baseline to Week 12
