Brief Summary:
In the pilot (Part A) of this study, multiple doses of CA-008 (vocacapsaicin) were evaluated for safety, tolerability, and PK. Doses were then selected for the expanded part (Part B) of the study, where CA-008 was compared to placebo. Patients had serial assessments of safety, PK, and drug effect.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Pain Intensity Scores [ Time Frame: 0 to Day 15 post dose ]
    Mean area under the curve (AUC) of the Numeric Rating Scale (NRS) weighted sum of pain intensity scores (at rest) from 0-10 where 0 is no pain and 10 is the worst pain imaginable for CA-008 compared to placebo. AUC is calculated using the standard trapezoidal rule from serial measures of NRS taken every 4 hours from 0-96 hours following surgery and twice daily from 96h to Day 15


Secondary Outcome Measures :
  1. Total Opioid Consumption [ Time Frame: 0 to Day 15 post dose ]
    CA-008 versus placebo comparison, total opioid consumption in oral morphine equivalents
