August 11, 2026 updated by: Biosplice Therapeutics, Inc.

A Phase 3, Multicenter, Randomized, Double Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of a Single Injection of Lorecivivint 0.07 mg in Subjects With Moderate to Severe Osteoarthritis Pain of the Knee

This phase 3 study was a multicenter, randomized, double-blind, placebo-controlled study of lorecivivint injected intra-articularly (IA) into the target (most painful) knee joint of moderately to severely symptomatic osteoarthritis (OA) subjects at a single dose of 0.07 mg lorecivivint per 2 mL injection. This study utilized standard outcomes to evaluate the safety and efficacy of lorecivivint.

Detailed Description

SM04690-OA-21 was a phase 3, 16-week multicenter, randomized, double-blind, placebo-controlled, parallel group study investigating the safety, tolerability and efficacy of LOR 0.07 mg (compared with PBO) injected into the target knee joint of moderately to severely symptomatic knee OA subjects.

Patient-reported outcomes included Pain Numeric Rating Scale (NRS) [0-10], Western Ontario and McMaster Universities Arthritis Index (WOMAC), and Patient Global Assessment (PGA) of knee osteoarthritis.

The primary efficacy endpoint was change from baseline in target knee Pain NRS at Week 12. Secondary endpoints included change at Week 12 in WOMAC Function and PGA.

  • Intra-articular (IA) injection into the target knee with a therapeutic aim including, but not limited to hyaluronic acid, platelet-rich plasma (PRP), and stem cell therapies within 26 weeks prior to Day 1; or IA glucocorticoids within 12 weeks prior to Day 1 allowed
  • Previous treatment with lorecivivint (SM04690)
  • Participation in a clinical research trial that included the receipt of an investigational product or any experimental therapeutic procedure within 26 weeks prior to the Screening Visit, or planned participation in any such trial
  • Subjects requiring the use of opioids > 1x per week within 12 weeks prior to Day 1
  • History of malignancy within the last 5 years; not including subjects with prior history of adequately treated in situ cervical cancer or basal or squamous cell skin cancer

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline OA Pain in the Target Knee as Assessed by Weekly Average of Daily Pain Numeric Rating Scale (NRS) at Week 12
Time Frame: Baseline to Week 12

Evaluate change from baseline OA pain in the target knee as assessed by weekly average of daily pain NRS at Week 12.

The pain NRS is an 11-point scale [0-10] for subject self-reporting of average knee pain in the last 24 hours; 0 indicates no pain, and 10 indicates pain as bad as you can imagine.
Baseline to Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline OA Function as Assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscore (WOMAC Function) at Week 12
Time Frame: Baseline and Week 12

Evaluate change from baseline OA function as assessed by WOMAC Function at Week 12. The WOMAC is a widely-used, proprietary outcome measurement tool used to evaluate the condition of subjects with OA of the knee and hip, including pain (5 questions), stiffness (2 questions) and physical functioning (17 questions) of the joints. Each question is measured on an 11-point NRS scale [0-10], where 0 indicates no pain / no stiffness / no difficulty, and 10 indicates extreme pain / extreme stiffness / extreme difficulty.

For analysis, WOMAC Function scores were scaled to 0 to 100, where 0 represents "No Functional Difficulty" and 100 represents "Extreme Functional Difficulty".
Baseline and Week 12
Change From Baseline OA Disease Activity as Assessed by Patient Global Assessment at Week 12
Time Frame: Baseline and Week 12
Evaluate change from baseline OA disease activity as assessed by Patient Global Assessment at Week 12. The Patient Global Assessment is an 11-point NRS [0-10] for subject self-reporting of how they feel their target knee is impacting them. For analysis, PGA scores were scaled to 0 to 100, where 0 represents "Very Good" and 100 represents "Very Bad".
Baseline and Week 12
