Study to Evaluate the Safety and Preliminary Efficacy of IDCT, a Treatment for Symptomatic Lumbar Intervertebral Disc Degeneration
- Conditions
- Degenerative Disc Disease
- Interventions
- Registration Number
- NCT03347708
- Lead Sponsor
- DiscGenics, Inc.
- 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.
- 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).
Recruitment & Eligibility

- Sex
- All
- Target Recruitment
- 60
The subject must have:
- Diagnosis of early to moderate degenerative disc disease (DDD), Modified Pfirrmann Grade 3-7.
- 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 and ODI score of 30 to 90.
The subject is excluded if he/she has:
- 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.
- Evidence of dynamic instability on lumbar flexion-extension radiographs.
- Grade 2 or higher spondylolisthesis at the target disc, lumbar spondylitis or other undifferentiated spondyloarthropathy, or Type III Modic changes around the target disc.
- Clinical suspicion of a full thickness annular tear at the target disc or other abnormal disc morphology.
- Clinical suspicion of facet pain as primary pain generator.
- Subjects who test positive for communicable disease, have significant systemic disease, or are prone to infection.
- Patients who are deemed unsuitable for clinical study participation by the investigator.

Group Intervention Description High Dose IDCT IDCT Single intradiscal injection with High Dose IDCT (9M cells). Low Dose IDCT IDCT Single intradiscal injection with Low Dose IDCT (3M cells). Saline Saline Solution Single intradiscal injection with saline solution. Sodium Hyaluronate Vehicle Sodium Hyaluronate Single intradiscal injection with Sodium Hyaluronate Vehicle.
- Primary Outcome Measures
Name Time Method Efficacy (Pain) 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.
Safety as measured by number of Adverse Events 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
- Secondary Outcome Measures
Name Time Method Disability 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
