Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 424 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-07-31

Brief Summary

The primary purpose of this study is to determine if duloxetine 60 mg once daily (QD) reduces pain severity in patients with osteoarthritis (OA) knee pain compared with placebo.

Conditions

Osteoarthritis Knee Pain

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

DLX30-PLA

Per the protocol, patients randomized to the duloxetine group were to receive duloxetine for the entire 13-week acute treatment period. Patients were to start at a 30 mg daily (QD) dose of duloxetine for 1 week, then increase to 60 mg QD of duloxetine for the following 12 weeks. However, due to a study drug labeling error, patients randomized to this group received 30 mg of duloxetine for the initial 1-week, but received placebo instead of receiving 60 mg QD of duloxetine for the next 12 weeks. The resulting unintended, mixed treatment group was labeled as DLX30-PLA throughout this document. Per protocol, the last week of the study (week 14) was intended to be a 1-week taper period. Patients in this treatment group were to receive 30 mg QD of duloxetine during that week, and that did occur per protocol.

Per the protocol, patients randomized to the placebo group were to receive placebo for the entire 13-week acute treatment period. Patients were to start on placebo for the first week, then continue on placebo for the following 12 weeks. However, due to a study drug labeling error, patients in this group received placebo for the initial 1-week, but received 60 mg QD of duloxetine instead of receiving placebo for the next 12 weeks. The resulting unintended, mixed treatment group was labeled as PLA-DLX60 throughout this document. Per protocol, the last week of the study (week 14) was intended to be a 1-week taper period. Patients in this treatment group were to receive placebo that week, and that did occur per protocol.
