Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to evaluate the safety and tolerability of TG-C in subjects with chronic discogenic lumbar back pain due to degenerative disc disease. Participants will be administered a single intradiscal injection or subcutaneous injection for sham and followed up with in-clinic visits and telephone calls for 24 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A Phase I, Double-blind, Randomized, Sham-controlled, Dose-response, Study Evaluating the Safety and Tolerability of TG-C in Subjects with Chronic Discogenic Lumbar Back Pain due to Degenerative Disc Disease at 6 and 12 Months, male or female subjects with chronic discogenic lumbar back pain due to degenerative disc disease at one level. TG-C is to be administered by a single intradiscal injection to the damaged disc via fluoroscopic guidance. Sham will be a normal saline subcutaneous injection. Subjects will be followed for 24 months with in-clinic visits and telephone calls after study drug administration.
