Full Study Name

An Open-Label Study to Assess the Safety of Repeat Administration of FX006 to Patients With Osteoarthritis of the Knee (IRB no. 46557)


This study focuses on patients diagnosed with osteoarthritis (OA) of the knee. The purpose of the study is to examine the use of an investigational drug called FX006 on patients with symptomatic OA of the knee. OA produces pain in the knee (and other joints) that is typically worsened by activities such as long-distance walking or climbing stairs and is alleviated by rest. Researchers aim to determine the overall safety and tolerability of administering FX006 more than once. The drug is being developed to potentially treat patients with symptomatic OA of the knee.

FX006 is a new form of a steroid injection already available for this condition, triamcinolone acetonide (Kenalog-40). The active ingredient of FX006 is also triamcinolone acetonide, but FX006 is designed to relieve the pain for longer than the available treatment.
