About

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.

Full 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).

Enrollment: 38 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• 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
• 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.
• 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.
• 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.
