The goal of this clinical trial is to find out if a new medicine can help people who have long-lasting back pain caused by damaged spinal discs. The study will also check if the medicine is safe to use.
The main questions this study aims to answer are:
Is the medicine safe, and what amount works best? Can it reduce long-term back pain?
Researchers will test a medicine called CBT005, which contains a healing protein, by injecting it into the spinal discs. They will watch closely to see how people respond to the treatment.
Participants will:
Receive one study injection into the spinal disc Visit the clinic in person during the first 12 months for checkups Receive phone calls at 24 and 36 months to see how they are doing Still be able to get other pain treatments in the future, including surgery, if needed
