Обзор

A Randomized, Double-Blind, Placebo-Controlled, Phase 2 Study to Determine the Efficacy, Safety, and Dosing of TG-C in Adult Subjects with Symptomatic Early Hip Osteoarthritis. TG-C will be administered to the target hip by a single ultrasound (or fluoroscopy)-guided, intra-articular injection with image capture showing correct injection of study drug into the femoroacetabular joint. Patients will be followed for 12 months for safety and efficacy.

Подробное описание

This protocol is designed to assess the safety and efficacy of TG-C in treating symptoms of osteoarthritis of the hip and determining disease modifying effects of TG-C. TG-C will be compared to normal saline as a control. 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 12 months for both safety and efficacy.

• Биопрепарат TG-C
  2 mL injection of non-transduced human chondrocytes and irradiated transduced human GP2-293 cells expressing TGF-B1.
