• Has a history of total or partial knee replacement, arthroplasty, or other knee surgery on the target knee.
• In the investigator's opinion, has had significant injury involving the target knee within the 6 months before Screening.
• Has skin lesions or wounds on or near the target knee at Screening or at Baseline (Day 1) that, in the investigator's opinion, would affect absorption of the medication.

• Has used gabapentin, pregabalin, antiepileptics, or specific antidepressants (i.e., tricyclics, serotonin norepinephrine reuptake inhibitors, or selective serotonin reuptake inhibitors) to treat pain in the 14 days before Screening. Other uses not related to the pain treatment may be permitted at the medical monitor's discretion provided they have been at a stable dose for at least 90 days.
• Has had intra articular (IA) injections of corticosteroids, hyaluronic acid, or viscosupplements (e.g., Synvisc®) to the target knee within the 12 weeks before Screening
• Has had IA or intravenous (IV) stem cell therapy in the 6 months prior to Screening
• Is receiving or is planning to receive concomitant nonpharmacologic treatments (e.g., physiotherapy, acupuncture) that in the investigator's opinion could confound efficacy assessments within 14 days of Day 1.
