What this Trial Is About

Researchers are evaluating the safety and effectiveness of a treatment called Intradiscal Cell Therapy (IDCT) for adults with mild to moderate, symptomatic lumbar degenerative disc disease affecting a single disc level between L3 and S1. This Phase III study compares IDCT to a sham procedure in a randomized, double-blinded, controlled trial involving about 162 participants. The study includes a 52-week primary period followed by another 52-week follow-up, totaling 104 weeks. Participants will be randomly assigned in a 2:1 ratio to receive either a single injection of IDCT containing 9 million cells per mL into the target disc or a sham needle insertion without active treatment. The injection is given as a 1 mL dose directly into the affected disc. Screening includes MRI and X-ray imaging to confirm eligibility and the location of disc degeneration. Randomization occurs 7 to 14 days before treatment. Throughout the study, participants will undergo assessments including pain measurement using the Visual Analogue Scale and disability evaluation with the Oswestry Disability Index at multiple time points up to two years. Researchers will also monitor adverse events and other health outcomes, including quality of life, disc volume changes, medication use, and treatment failure rates. The study involves informed consent, regular visits, and imaging to ensure safety and collect data.
