Overview
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.
Detailed Description
This is a Phase I, 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).

Eligibility Criteria
Inclusion Criteria
- •Diagnosis of early to moderate degenerative disc disease (DDD), Modified Pfirrmann Grade 3-
- •Chronic low-back pain for at least 6 months prior to screening; unresponsive to at least 3 months of conservative care.
- •Low-back pain of 40 to 90 mm on the VAS
- •ODI score of 30 to 90.
Exclusion Criteria
- •Symptomatic involvement of more than one lumbar disc.
- •Other persistent pain/nerve issues including, for example, radiculopathy, leg pain, Cauda Equine syndrome, etc.
- •Fracture of the spine, previous lumbar spine surgery or previous treatment of the target disc.

Outcomes
Primary Outcomes
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
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
Secondary Outcomes
- Disability(1 year)
- Efficacy (Pain): JOABPEQ(1 year)
