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 two controls (saline, Sodium Hyaluronate vehicle) 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 Drug: Saline Solution Drug: Sodium Hyaluronate Phase 1 Phase 2

Detailed Description:

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).

Primary Outcome Measures :
  1. Safety as measured by number of Adverse Events [ Time Frame: 2 Years ]
    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 grade 2 or greater AEs and SAEs observed from Day 1 to week 104

  2. Efficacy (Pain) [ Time Frame: 1 Year ]
    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: 2 Years ]
    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

Other Outcome Measures:
  1. Exploratory [ Time Frame: 2 Years ]
    Imaging parameters will be evaluated via radiological evaluations

Inclusion Criteria: The subject must have:

  1. Diagnosis of early to moderate degenerative disc disease (DDD), Modified Pfirrmann Grade 3-7.
  2. Chronic low‑back pain for at least 6 months prior to screening; unresponsive to at least 3 months of conservative care.

  8. Subjects who test positive for communicable disease, have significant systemic disease, or are prone to infection.
  9. Patients who are deemed unsuitable for clinical study participation by the investigator.
