Official title
A Randomized, Double-Blind, Placebo-Controlled, Titration-to-Effect Study of Orally Administered CR845 in Patients With Osteoarthritis of the Hip or Knee
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study schedule consists of a Screening Period (up to 14 days), a blinded 4- week Titration-to-Effect Period with weekly visits, a blinded 4-week Maintenance Treatment Period at the optimal dose level determined for each patient, and a 1-week Follow-up Period. Eligible patients will be randomized to receive either CR845 or placebo in a 2:1 ratio. Every patient will be started on a 1-mg dose of CR845 or matching placebo. During the post-randomization Titration-to-Effect period, the dose of study drug may be increased to 2.5 mg or 5 mg in a double-blind fashion. Patients may know their dose is being changed but will not know whether they were randomization to active study drug or placebo. Approximately 330 patients will be enrolled in this study.
