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

Study Purpose

A randomized, double-blind, placebo-controlled, multi-center, phase 3 study to determine the safety and efficacy 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.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03203330
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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 KL 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 dosing for subjects who do not enroll in the Long Term Safety study.
