A Study Of The Effect Of CE-224535 On Knee OA (Osteoarthritis) Pain

December 3, 2018 updated by: Pfizer

A 2 Week, Randomized, Double Blind, Placebo And Positive Controlled, Parallel Group, Multicenter Study Of CE-224,535 In Subjects With Osteoarthritic Pain Of The Knee

CE-224535 is a new medication being developed as an analgesic and anti-inflammatory agent for the treatment of the signs and symptoms of osteoarthritis (OA). The purpose of this study is to evaluate the analgesic and anti inflammatory efficacy and safety of CE 224,535 versus placebo and naproxen treatment in patients with OA knee pain.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Time Frame: Day 1-14
Day 1-14

Secondary Outcome Measures

Secondary Outcome Measures
