Pacira Pharmaceuticals, Inc208 enrolled

Overview

This is an Open-label Study to Assess the Safety of Repeat Dose of FX006 Administered to Patients with Osteoarthritis (OA) of the Knee

This study is an open-label, repeat administration design of 32 mg FX006. The study will be conducted in male and female patients ≥ 40 years of age with symptomatic OA of the knee. Eligible patients will be offered participation to receive an initial intra-articular (IA) injection of FX006 administered to the index knee at Day 1. Patients who receive an initial injection of FX006 will return at Weeks 4 and 8 before being evaluated at 12, 16, 20 and 24 weeks for repeat administration. At the first evaluation where the patient has been determined to meet repeat administration eligibility criteria, the patient will be eligible to receive a second IA injection of FX006. Patients who are eligible to receive a second injection will be evaluated for a total of 52 weeks post initial injection at: Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48 and 52, regardless of the time at which they receive their second injection. In addition, X-rays will be completed at Screening and Week 52 or End of Study (EOS) for assessment of safety. Patients that do not benefit from the initial treatment as determined by evaluation at Week 12 will complete the study at the Week 12 follow-up visit. Patients who are not eligible for a second injection of FX006 after evaluation at Weeks 12, 16, 20, and 24 will complete the study at the Week 24 follow-up visit.

Outcomes

Primary Outcomes

Total Number of Treatment Emergent Adverse Events (TEAEs) in Patients With Symptomatic Osteoarthritis (OA) of the Knee Who Received Two Doses of 32 mg FX006

Analyses of adverse events (AE) were performed for events considered treatment-emergent (TE) in patients who received two doses of 32 mg FX006. TE was defined as any AE with onset after administration of the 1st dose of study drug or any event present at baseline but worsened in intensity through the study. Severity was graded by the PI using the Common Terminology Criteria for AEs Version 4.0. Grading went from Grade 1 (Mild) to Grade 5 (Death Related to AE).
