This is a clinical research trial with a medication that has not been used this way in humans before.  Furthermore, you may not get benefit from the clinical trial medication.

You should be aware that patients may be initially disappointed when they receive antibiotic treatment because they expect to get well quickly. It can take up to 12 months before your Chronic Low Back Pain is better. First the bacteria must be killed; it then takes some months for the tissues to heal and the muscles to regain their strength.  Reduction in pain may be only after this process.  When this happens, the patient may experience less back pain. This is why you will stay in the trial for a year to assess your progress.

When your pain slowly improves you can start gentle exercise and slowly progress within your pain limits.
