This is a Phase I, first-in-human, randomized, double-blind, vehicle and placebo-controlled, parallel-group, multi-center study in subjects with single-level, symptomatic lumbar intervertebral disc degeneration (\>6 months) and unresponsive to conservative therapy for at least 3 months. The study will compare single intradiscal injections of high and low dose IDCT with two control groups (saline, Sodium Hyaluronate).
8 study visits will be completed by all subjects; screening, day 1 (injection day), week 4, week 12, week 26, week 52, week 72 and week 104. The subject will be assessed for safety and efficacy utilizing VAS and ODI questionnaires alongside radiographic evaluations. The study will have a 1 year follow-up and a 1 year extension period (total 2 years).
