Inclusion criteria
Males and females between 40 and 80 years of age, inclusive, in general good health
Ambulatory (single assistive devices such as canes allowed if needed less than 50% of the time, subjects requiring a walker are excluded)
Established diagnosis of primary femorotibial OA in the target knee by standard American College of Rheumatology (ACR) criteria for at least 6 months (clinical AND radiographic criteria); if bilateral knee OA is present, the target knee is defined as the knee with greater pain at screening based on the subject's evaluation and the Investigator's clinical judgment
Radiographic disease Stage 2 or 3 in the target knee according to the Kellgren-Lawrence grading of knee OA as assessed by independent central readers
Screening pain visual analog scale (VAS) score of 30-80 mm (on a scale of 0-100 mm) for the target knee while on symptomatic oral treatment at screening (if the subject requires oral treatment)
Total WOMAC score of 72-192 (out of 240) for the target knee while on symptomatic oral treatment at screening (if the subject requires oral treatment)
Willingness to omit the following for 24 hours prior to all Study Visits, excluding the Screening Visit:
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 Day 1 visit must occur while enrollment into the study is open
Exclusion criteria
Women who are pregnant or lactating
Women of childbearing potential (i.e., who are not surgically sterile or postmenopausal as defined by no menstrual periods for 12 consecutive months and no other biological or physiological cause for amenorrhea can be identified); males who are sexually active and have a partner who is capable of becoming pregnant, neither of which have had surgery to become sterilized, who are not using an effective method of birth control (e.g., surgically-implanted hormonal therapy, intrauterine devices or oral birth control with barrier method)
Body mass index (BMI) >40
Partial or complete joint replacement in the target knee
Previous exposure to SM04690
Major surgery (e.g., interventional arthroscopy) in the target knee within 52 weeks prior to any study injection
Any planned or elective surgery during the study period
Significant and clinically evident misalignment of the target 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 cancer or basal or squamous cell skin cancer are eligible. Subjects with other malignancies are eligible if they have been continuously disease free for at least 5 years prior to any study injection
Clinically significant abnormal Screening Visit hematology values, blood chemistry values, HbA1c, 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 pain assessment of the target knee, including, but not limited to, inflammatory rheumatic conditions such as rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, diabetic neuropathy, pseudogout, gout, and fibromyalgia
Other conditions that, in the opinion of the Investigator, could affect pain assessment of the target knee, including, but not limited to, symptomatic hip osteoarthritis and symptomatic degenerative disc disease
Any diagnosed psychiatric condition that includes, but is not limited to, a history of mania, bipolar disorder, psychotic disorder, schizophrenia, 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 within 12 weeks prior to any study injection; the last date of participation in the trial, not the last date of receipt of investigational product, must be at least 12 weeks prior to Study Visit Day 1
Treatment of the target knee with systemic or intra-articular corticosteroids (e.g., methylprednisolone) within 8 weeks prior to Study Visit Day 1
Viscosupplementation (e.g., hyaluronic acid) in the target knee within 24 weeks prior to Study Visit Day 1
Effusion of the target knee clinically requiring aspiration within 12 weeks prior to Study Visit Day 1
Use of electrotherapy, acupuncture, and/or chiropractic treatments for knee OA within 4 weeks prior to Study Visit Day 1
Any known active infections, including 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)
Subjects taking prescription medications for OA who have not maintained a stable therapeutic regimen for a minimum of 12 weeks prior to Study Visit Day 1
Subjects requiring the chronic use (i.e., regular and consistent use for ≥ 12 weeks) of the medications listed below within 12 weeks prior to Study Visit Day 1:
Any chronic condition that has not been well controlled or subjects with a chronic condition who have not maintained a stable therapeutic regimen of a prescription therapy for a minimum of 12 weeks prior to Study Visit Day 1. In addition, the following subjects will be excluded:
Subjects who have a current or pending disability claim, workers' compensation, or litigation(s) that may compromise response to treatment
Subjects who are immediate family members (spouse, parent, child, or sibling; biological or legally adopted) of personnel directly affiliated with the study at the investigative site, or are directly affiliated with the study at the investigative site
Subjects employed by Samumed, LLC, or any of its affiliates or development partners (that is, an employee, temporary contract worker, or designee) responsible for the conduct of the study
