You may not be if

• Patients using non-steroidal anti-inflammatory agent must be on a consistent regimen, dose, and medication for at least 8 weeks prior to enrollment
• Part A only: Ambulatory persons with osteoarthritis (OA) of the knee and baseline pain with a mean of ≥ 4 and ≤ 9 points on the 24-hour mean pain score (on the 11-point Numeric Rating Scale) for at least five of the seven days during the screening period.
• Part B only: Ambulatory persons with painful osteoarthritis (OA) of the knee for at least six months.
• Part B only: Patients with OA must have Kellgren-Lawrence scores 1 through 4 in the target knee
• Part B only: Patients must have a baseline pain ≥6 on the WOMAC Index pain subscale as derived from the KOOS.
• Any condition, including laboratory findings 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 or prevent the Patient from fully participating in all aspects of the study
• Patients with clinically significant co-existing conditions of the cardiovascular, renal, gastrointestinal, respiratory, nervous, metabolic, or hematologic/ immune systems
• Patients with a history of diabetes mellitus according to the American Diabetes Association criteria or patients previously diagnosed by a qualified physician as having diabetes (American Diabetes Association Standards of Medical Care in Diabetes 2016)
• Patients with a history of cardiac rhythm disturbances, abnormal ECG intervals, or use of medications known to impact ECG intervals
• Patients who have undergone diagnostic arthroscopy of the Target Knee in the previous six months
• Patients who have undergone arthroscopic surgery in the last two years prior to the screening visit (including microfracture and menisectomy) on the Target Knee.
• Patients anticipated to have arthroscopic surgery on either knee at any time during the study period
• History of previous total or partial knee arthroplasty in either knee
• Part A only: Patients with an effusion at the screening visit which, in the opinion of the investigator following examination and discussions with the Patient, requires drainage for symptom relief
• Patients who have received intra-articular treatment with steroids or hyaluronic acid derivatives within the last 16 weeks prior to screening
• Patients who use, or have used in the 8 weeks prior to screening, opioid analgesics (with exception of mild opioid analgesics)
• Patients who have had regenerative joint procedures on any joint including, but not limited to, platelet-rich plasma injections, mesenchymal stem cell transplantation, autologous chondrocyte transplantation, or mosaicplasty
