* Participants with a mean of the 24-hour average pain severity scores (round off to a whole number) of 4 or higher, as calculated from the patient diary for 7 days immediately before Visit 2

Exclusion Criteria:

* Participants who have undergone renal transplant or who are currently on renal dialysis.
* Participants who have a history requiring pharmacotherapy within the past year or current history of psychiatric disease, such as mania, bipolar disorder, depression, anxiety disorder, or eating disorder.
