• Female participants: women not of child-bearing potential due to surgical sterilization (at least 6 weeks post surgical bilateral oophorectomy with or without hysterectomy or tubal ligation) confirmed by medical history, or menopause
• Body weight greater than 40 kilograms (kg) and less than 120 kilograms (kg) with a body mass index (BMI) between 19-35 kilograms per square meter (kg/m^2) inclusive
• Participant with osteoarthritic knee based on disease diagnostic criteria as presented in the Inclusion Disease Criteria, below
• Blood pressure and pulse rate in supine and standing positions, within normal reference ranges for the population and investigator clinical research unit (CRU), or results with acceptable deviations that are judged to be not clinically significant by the investigator
• Have clinical laboratory test results within normal reference range for the population or investigator clinical research unit (CRU), or results with acceptable deviations that are judged to be not clinically significant by the investigator
• Have venous access sufficient to allow for blood sampling
• Have agreed to maintain the same activity level throughout the course of the study

Inclusion Disease Criteria:

• Have a unilateral or bilateral osteoarthritis (OA) of the knee diagnosed according to the American College of Rheumatology (ACR) criteria. The clinical diagnosis of osteoarthritis (OA) will be confirmed by the American College of Rheumatology (ACR) clinical and radiographic criteria for classification of idiopathic osteoarthritis (OA) of the knee based upon the following criteria:

• Knee pain for at least 14 days per month for the 3 months before screening

• Have a Kellgren and Lawrence grade of I, II, III or IV
• Have a mean score of at least 4 (moderate) and less than or equal to 8 (moderate-severe) on the 24-hour average pain score (0-10) (question 1) in the participant e-diary from screening to randomization for the knee joint during walking
• Discontinued use of all analgesic medications (including over-the-counter [OTC] analgesics/Non-Steroidal Anti-Inflammatory Drug [NSAID]) at least 2 weeks prior to randomization (participants are allowed limited use of analgesic medications)

• Have intercurrent illness or clinically significant adverse events
• Have increased risk of seizures as evidenced by a history of seizures, stroke, surgery to the cerebral cortex, or head trauma with loss of consciousness
• Have an alanine aminotransaminase (ALT) greater than 2.5 times Upper Limit of Normal (ULN) at Screening, based on reference ranges of the local laboratory. Moderate or greater hepatic impairment
• Have prior renal transplant, current renal dialysis or severe renal insufficiency, or serum creatinine laboratory value greater than 1.5 times Upper Limit of Normal, based on the reference ranges of the local laboratory
