Forward-looking statements in this presentation include, among other things, statements about: the success and timing of our clinical trials, including our pivotal clinical program for I.V. CR845 in acute pain; our plans for future clinical
development of I.V. CR845 for uremic pruritus; our plans to develop and commercialize I.V. CR845 and our other product candidates, including Oral CR845; the size of the potential markets for pain management, including the postoperative and chronic
pain market and the uremic pruritus market; the trial design for future clinical trials, including the proposed Phase 2b oral clinical trial for CR845 and projected clinical milestones for I.V. CR845 and Oral CR845. These statements involve
known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements.

Uremic Pruritus POC Phase 2 Trial
Design Primary Objectives To evaluate the PK profile of repeated doses of CR845 in hemodialysis patients over a one-week treatment period Part A To evaluate the efficacy of CR845 compared to placebo in reducing the intensity of itch over a 2-week
treatment period (1 dose selected based on Part A, 3 times/week post-dialysis) in hemodialysis patients with uremic pruritus Part B
