What was measured

Participants reported responses to the BPI Worst Pain NRS. The BPI Worst Pain NRS ranged from 0 to 10, where 0 is "no pain" and 10 is "pain as bad as you can imagine." A responder was defined as a participant who: (i) experienced a decrease of at least 30% in the mean BPI Worst Pain NRS item and (ii) did not experience a 30% or greater increase in narcotic analgesic use.

Analysis population: The ITT Set consisted of participants who were randomized to a study treatment regimen.
