Study Endpoints
Primary Endpoints
Improvement in the Maximum Daily NRS-Pain Score at Day 84
Day 1 through Day 84

The numeric rating scale for pain (NRS-Pain) consists of an 11-point NRS ranging from 0 (no pain) to 10 (pain as bad as you can imagine). A rating of 1-3 is considered mild pain; 4-6, moderate pain; and 7-10, severe pain. Participants will be asked to report their maximum daily pain using the NRS-Pain. Participants will call into an interactive voice response e diary system (IVRS) and record the number that best reflects their maximum amount of pain experienced in the last 24 hours. Participants will be asked to call at the same time each day, preferably before bedtime. Longitudinal trends over the course of the treatment period will be modeled and used to estimate difference between means at baseline and Day 84 for each treatment group.

Secondary Endpoints
