Study summary

The purpose of this study is to identify the dose(s) of IDEA-033 that will provide a meaningful effect for treating osteoarthritis of the knee.

Read the detailed description

The objective of this double-blind, placebo-controlled, randomized study is to evaluate the safety of and to identify the dose(s) of IDEA-033 that will provide a minimum clinically meaningful effect for treating the signs and symptoms of osteoarthritis of the knee. This study will also compare the safety profile of the three doses of IDEA-033 in treating the signs and symptoms associated with osteoarthritis for 12 weeks. The primary hypothesis is that at least one of the three doses of IDEA-033 is superior to placebo with respect to three primary efficacy endpoints of WOMAC Pain, WOMAC Physical Function, and Subject Global Assessment of Response to Therapy. A second hypothesis is that there is an increase in efficacy with increasing doses of IDEA-033.

Patients will receive one of five treatments for 12 weeks:Three doses of IDEA-033, or naproxen 1 g over-encapsulated tablet + placebo or placebo

What researchers measure

Primary outcomes

  1. Change from baseline at Week 12 on pain subscale and physical function subscale on the WOMAC Osteoarthritis Index. Subject global assessment of response to therapy (SGART) on a five-point Likert scale at Week 12.

Secondary outcomes

  1. Change from baseline at Weeks 2, 6, 9 for WOMAC pain and physical function scores and SGART. Mean change from baseline for the entire on-therapy period for WOMAC pain and physical function scores and SGART.
