Brief Summary:
The purpose of this study is to compare the safety and preliminary efficacy of intradiscal injections of two doses of IDCT (Discogenic Cells + Sodium Hyaluronate vehicle) and one sham control in subjects with chronic low back pain due to Degenerative Disc Disease (DDD) at one lumbar level from L3 to S1.

Condition or disease Intervention/treatment Phase
Degenerative Disc Disease Biological: IDCT Procedure: Sham Phase 1 Phase 2

Detailed Description:

This is a Phase I/II, randomized, double-blind, sham-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 one sham control group.

6 study visits will be completed by all subjects; screening, day 1 (injection day), week 4, week 12, week 26 and week 52. The subject will be assessed for safety and efficacy utilizing VAS, ODI and JOABPEQ questionnaires alongside radiographic evaluations. The study will have a 6 month follow-up and a 6 month extension period (total 1 year).

Primary Outcome Measures :
  1. Safety as measured by number of Adverse Events [ Time Frame: 1 year ]
    To evaluate the safety and tolerability of a single injection of IDCT in subjects with single-level, symptomatic early to moderate lumbar intervertebral disc degeneration as measured by the incidence of AEs and SAEs observed from Day 1 to week 52

  2. Efficacy (Pain): Visual Analogue Scale (VAS) [ Time Frame: 6 months ]
    Evaluate the effect of IDCT on pain as measured by a 0-100mm Visual Analogue Scale (VAS). 0: no pain, 100: worst pain imaginable

Secondary Outcome Measures :
  1. Disability [ Time Frame: 1 year ]
    Evaluate the effect of IDCT on disability as measured by the Oswestry Disability Index (ODI). Score of 0%: no disability, score of 100%: severely disabled

  2. Efficacy (Pain): JOABPEQ [ Time Frame: 1 year ]
    Evaluate the effect of IDCT on pain as measured by JOABPEQ. The range of the score for each domain is from 0 to 100, with higher scores indicating a better condition.

Other Outcome Measures:
  1. Radiographic Assessments [ Time Frame: 1 year ]
    To evaluate morphologic changes of treated intervertebral discs using MRI & X-Ray assessments.
