Study to Determine the Efficacy and Safety of TG-C in Subjects With Kellgren/Lawrence Grade 2 or 3 OA of the Knee

Degenerative Osteoarthritis Clinical Trial

Official title:
A Randomized, Double-Blind, Placebo-Controlled, Multi-Center, Phase 3 Study to Determine the Efficacy and Safety of TG-C in Subjects With Kellgren and Lawrence Grade 2 or 3 Osteoarthritis of the Knee

Clinical Trial Summary

A randomized, double-blind, placebo-controlled, multi-center, phase 3 study to determine the efficacy and safety of TG-C in subjects with Kellgren and Lawrence Grade 2 or 3 Osteoarthritis of the Knee, Osteoarthritis Research Society International (OARSI) medial joint space narrowing (JSN) Grade 1 or 2 of the knee joint. TG-C is to be administered by a single intra-articular injection to the damaged joint area via ultrasound guidance. Patients will be followed for 24 months for safety and efficacy.

Clinical Trial Description

This protocol is designed to assess the safety and efficacy of TG-C in treating symptoms of osteoarthritis of the knee and determining disease modifying effects of TG-C. This study is intended for the treatment of patients with K&L Grade 2 and 3 osteoarthritis and OARSI JSN Grade 1 and 2. Assessments will be made on both the symptomatic effects of pain (VAS), function (WOMAC), and Quality of Life (SF-12) as well as the physical effects (JSW, MRI evaluations of whole knee joint organ tissues and structure) and biochemical biomarkers. This is a placebo-controlled study, TG-C will be compared to normal saline as a control. Additionally, this protocol is designed to evaluate the safety of TG-C. Safety will be evaluated by observation of the injection site for irritation or other effects, the incidence and severity of adverse events, and changes in physical examination findings, radiographic criteria, and laboratory tests. Patients will be followed for 24 months for both safety and efficacy with annual cancer surveillance questionnaires through 15 years post dose for subjects who do not enroll in the Long Term Safety study. ;
