Patient-Reported and Radiographic Outcomes in Evaluating Lorecivivint (SM04690) for the Treatment of Knee Osteoarthritis

Completed · Phase 3 · Has a placebo group

Conditions studied: Knee Osteoarthritis

In brief

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

• Diagnosis of femorotibial OA in the target knee by standard American College of Rheumatology (ACR) criteria at the Screening Visit (clinical AND radiographic criteria); OA of the knee is not to be secondary to any rheumatologic conditions (e.g., rheumatoid arthritis)
• mJSW by radiograph between 1.5 and 4 mm, inclusive, in the target knee within 12 weeks of the Screening Visit as assessed by independent central readers
• Radiographic disease Stage 2 or 3 in the target knee within 12 weeks of the Screening Visit according to the Kellgren-Lawrence (KL) grading of knee OA as assessed by independent central readers
• Pain compatible with OA of the knee(s) for at least 26 weeks prior to the Screening Visit
• Primary source of pain throughout the body is due to OA in the target knee
• Body mass index (BMI) ≤ 40 kg/m2 at the Screening Visit
• Widespread Pain Index (WPI) score of ≤ 4 and a Symptom Severity Question 2 (SSQ2) score of ≤ 2 at the Screening Visit and Day 1
• Pain NRS scores recorded for the target knee on at least 4 out of the 7 days immediately preceding Day 1
• Pain NRS scores recorded for the nontarget knee on at least 4 out of the 7 days immediately preceding Day 1
• Daily OA knee pain diary average NRS intensity score ≥ 4 and ≤ 8 in the target knee on the 11-point (0-10) NRS scale for the 7 days immediately preceding Day 1
• Daily OA knee pain diary average NRS intensity score < 4 in the nontarget knee on the 11-point (0-10) NRS scale for the 7 days immediately preceding Day 1
• WOMAC Pain of 20-40 (out of 50) for the target knee at baseline regardless of if the subject is on symptomatic oral treatment (baseline questionnaire completed during the screening period prior to randomization)
• WOMAC Function of 68-136 (out of 170) for the target knee at baseline regardless of if the subject is on symptomatic oral treatment (baseline questionnaire completed during the screening period prior to randomization)
• Willingness to use an electronic diary daily in the evening for the screening period and 56-week study duration
• Negative drug test for amphetamine, buprenorphine, cocaine, methadone, opiates, phencyclidine (PCP), propoxyphene, barbiturates, benzodiazepine, methaqualone, and tricyclic antidepressants, unless any of these drugs are allowed per protocol and prescribed by a physician to treat a specific condition
• Subjects with depression or anxiety must be clinically stable for at least 12 weeks prior to the Screening Visit and, if on treatment for depression or anxiety, be on at least 12 weeks of stable therapy
• Full understanding of the requirements of the study and willingness to comply with all study visits and assessments
• Subjects must have read and understood the informed consent form (ICF), and must have signed and dated it prior to any study-related procedure being performed

You may not qualify if…

• Pregnant women, breastfeeding woman, and women who are not post-menopausal (defined as 12 months with no menses without an alternative medical cause) or permanently surgically sterile (includes hysterectomy, bilateral salpingectomy, and bilateral oophorectomy), who have a positive or indeterminate pregnancy test result at the Screening Visit or Day 1
• Women who are not post-menopausal or permanently surgically sterile who are sexually active, and who are not willing to use birth control during the study period
• Men who are sexually active and of reproductive potential, who have partners who are capable of becoming pregnant, and who are not willing to use birth control during the study period
• Significant malalignment of anatomical axis (medial angle formed by the femur and tibia) of the target knee (varus > 10°, valgus > 10°) by radiograph within 12 weeks of the Screening Visit as assessed by independent central readers
• Partial or complete joint replacement in either knee
• Currently requires use of a lower extremity prosthesis, and/or a structural knee brace (i.e., a knee brace that contains hardware)
• Any surgery (e.g., arthroscopy) in either knee within 26 weeks prior to Day 1
• 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
• Effusion of the target knee clinically requiring aspiration within 12 weeks prior to Day 1
• Use of electrotherapy, acupuncture, physical therapy, therapeutic ultrasound, and/or chiropractic treatments for knee OA within 4 weeks prior to Day 1
• Any bone fracture(s) within 26 weeks prior to the Screening Visit
• Previous treatment with SM04690
• Subjects who have previously failed screening on this protocol and fail to meet rescreening criteria
• Participation in a clinical research trial that included the receipt of an investigational product (IP) or any experimental therapeutic procedure within 26 weeks prior to the Screening Visit, or planned participation in any such trial
• Treatment with systemic (oral, intramuscular, or intravenous) glucocorticoids ≥10 mg prednisone or the equivalent per day within 4 weeks prior to Day 1, or subjects on <10 mg prednisone or the equivalent per day who have not maintained a stable regimen for at least 2 weeks prior to Day 1 in the opinion of the Investigator

• 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
• Clinically significant abnormal screening hematology values, blood chemistry values, or urinalysis values as determined by the Investigator
• Any condition, that, in the opinion of the Investigator, constitutes a risk or contraindication for participation in the study or that could interfere with the study objectives, conduct, or evaluation
• Other conditions that, in the opinion of the Investigator, could affect study endpoint assessments of either knee, including, but not limited to, peripheral neuropathy (e.g., diabetic neuropathy), symptomatic hip osteoarthritis, symptomatic degenerative disc disease, and patellofemoral syndrome
