   • Kellgren-Lawrence (K-L) grade 2 or 3 radiographic evidence at the screening visit as determined by a local radiologist or rheumatologist. If a radiograph is not available, one must be taken and the diagnostic criteria must be confirmed before randomization.

3. Subjects whose OA pain of the index knee is not adequately treated prior to the screening visit:

   • Subjects must have a self-reported average pain intensity rating of moderate or severe on a verbal rating scale (ie, none, mild, moderate, and severe) over the 7 days prior to the screening visit
4. The subjects must have "average pain over the last 24 hours" scores ≥ 4 and ≤ 9 on an 11-point numerical rating scale (NRS) for the index knee on ≥ 3 consecutive days during the pain assessment period and come in for randomization within 96 hours after the latest qualifying pain score entry
5. Subjects who are willing and able to stop taking any/all analgesic medications, including over-the-counter pain medications, opioids, marijuana, and topical analgesics for OA pain for the duration of the study, with the exception of study-specific rescue medication.
