(Modic 1) or vertebral body endplate bone oedema and fat (Modic 1 and 2) at a single
lumbar level.

- Average LBP NRS score at screening and at Day 1 pre-randomisation = 4 on chronic pain
medication and = 6 if not on chronic pain medication; it should be higher than the leg
pain NRS score

Maximum age
70 Years
Sex

Can healthy volunteers participate?
No
Key exclusion criteria
- Any vertebra with Modic 2 only lesions which:

1. in the opinion of the investigator, after deep palpation of the vertebral spine,
is contributing to the low back pain and/or

2. are present within 2 vertebrae from the target lumbar disc.

- The target lumbar disc has lost more than half its original anticipated height at the
centre or it is < 5mm in height over the central 15 mm portion

- A clear alternative cause for back pain

- Gross facet joint degeneration or cases where the investigator believes the primary
pain generator to be the facet joints

- Interventional back procedure in the 6 months prior to screening or major surgery in
the 12 weeks prior to screening

- History of alcohol abuse or drugs of abuse in the past 2 years

- Any other significant illness

- Previously been treated with antimicrobial agents for their low back pain or
previously received any antimicrobial intradiscal injection.
