MRI Study to Evaluate the Safety and Efficacy of SM04690 for Knee Osteoarthritis

Stopped early · Phase 2

Conditions studied: Knee Osteoarthritis

In brief

The purpose of this study was to evaluate the safety and efficacy of lorecivivint (LOR) injected in the target knee joint of moderately to severely symptomatic osteoarthritis (OA) subjects. Efficacy was primarily evaluated via magnetic resonance imaging (MRI).

Who can join

Age: 40 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Ambulatory (single assistive devices such as canes allowed if needed less than 50% of the time, subjects requiring a walker are excluded)
• 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)
• 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
• Daily OA knee pain diary average Numeric Rating Scale (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
• Pain NRS scores recorded for the target knee on at least 4 out of the 7 days immediately preceding Day 1
• Daily OA knee pain diary average NRS intensity score <4 in the non-target knee on the 11-point (0-10) NRS scale for the 7 days immediately preceding Day 1
• Pain NRS scores recorded for the non-target knee on at least 4 out of the 7 days immediately preceding Day 1
• Baseline mJSW by radiograph between 2 and 4 mm, inclusive, in the target knee at the Screening Visit as assessed by independent central readers
• Total WOMAC score of 96-192 (out of 240) for the target knee at Day 1 regardless of if the subject is on symptomatic oral treatment
• Negative drug test for amphetamine, methamphetamine, buprenorphine, cocaine, methadone, opiates, phencyclidine (PCP), propoxyphene, barbiturates, benzodiazepine, methaqualone, and tricyclic antidepressants, except if any such drugs are clinically indicated and allowed by the protocol at the Screening Visit
• Subjects with depression or anxiety must be clinically stable for 12 weeks prior to the Screening Visit and, if on treatment for depression or anxiety, be on 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, and must have signed it prior to any study-related procedure being performed
• Subject's Screening Visit must occur while enrollment into the study is open

You may not qualify if…

• Women who are pregnant, lactating, or have a positive pregnancy test result at the Screening Visit
• Women of childbearing potential who are sexually active, and who are not willing to use an acceptable method of birth control during the study period
• Men of childbearing potential who are sexually active and have a partner who is capable of becoming pregnant, neither of whom are agreeable to using an acceptable method of birth control during the study period
• Body mass index (BMI) > 40
• Partial or complete joint replacement in either knee
• Currently requires: a) regular use (in the opinion of the Investigator) of ambulatory assistive devices (e.g., wheelchair, parallel bars, walker, canes, or crutches), or b) use of a lower extremity prosthesis, and/or a structural knee brace (i.e., a knee brace that contains hardware)
• Radiographic disease Stage 0, 1, or 4 in the target knee at the Screening Visit according to the Kellgren-Lawrence (KL) grading of knee OA as assessed by independent central readers
• Previous treatment with lorecivivint (SM04690)
• Subjects who have previously failed screening on this protocol and fail to meet re-screening criteria
• Any surgery (e.g., arthroscopy) in either knee within 26 weeks prior to the Screening Visit
• Any surgery scheduled during the study period. Non-surgical invasive procedures conducted for a diagnostic or therapeutic purpose scheduled during the study period are not prohibited
• Significant and clinically evident misalignment of either knee that would impact subject function, as determined by the Investigator
• History of malignancy within the last 5 years; however, subjects with prior history of in situ basal or squamous cell skin cancer are eligible if completely excised. Subjects with other malignancies are eligible if they have been continuously disease free for at least 5 years prior to the Screening Visit
• Clinically significant abnormal screening hematology values, blood chemistry values, or urinalysis values as determined by the Investigator
• Any condition, including laboratory findings not included in the Screening Visit laboratory tests and findings in the medical history or in the pre-study assessments, 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
• Comorbid conditions that could affect study endpoint assessments of the target knee, including, but not limited to, rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, gout or pseudogout, and fibromyalgia
• 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
• Any diagnosed psychiatric condition that includes, but is not limited to, a history of mania, bipolar disorder, psychotic disorder, schizophrenia, schizoaffective disorder, major depressive disorder, or generalized anxiety disorder
• Participation in a clinical research trial that included the receipt of an investigational product or any experimental therapeutic procedure, or an observational research trial related to osteoarthritis within 8 weeks prior to to the Screening Visit, or planned participation in any such trial; the last date of participation in the trial, not the last date of receipt of investigational product, must be at least 8 weeks prior to the Screening Visit
• Any intra-articular injection into the target knee with a therapeutic aim including, but not limited to, viscosupplementation (e.g., hyaluronic acid), platelet-rich plasma (PRP), and stem cell therapies within 24 weeks prior to the Screening Visit; treatment of the target knee with intra-articular glucocorticoids greater than 12 weeks prior to the Screening Visit is allowed
• Treatment with systemic glucocorticoids greater than 10 mg prednisone or the equivalent per day within 4 weeks prior to the Screening Visit
• Effusion of the target knee clinically requiring aspiration within 12 weeks prior to the Screening Visit
• Use of electrotherapy, acupuncture, and/or chiropractic treatments for knee OA within 4 weeks prior to the Screening Visit
• Any known active infections, including urinary tract infection, upper respiratory tract infection, sinusitis, suspicion of intra-articular infection, hepatitis B or hepatitis C infection, and/or infections that may compromise the immune system such as human immunodeficiency virus (HIV) at Day 1
• Current use, or use within 12 weeks prior to the Screening Visit, of centrally acting analgesics
