Chronic Low Back Pain – Clinical trials

Persica has developed a new therapy to treat patients suffering from CLBP due to low-grade bacterial infection in the discs of the spine. These patients are experiencing a debilitating, long lasting condition that significantly affects their quality of life and for which existing treatments including exercise, physiotherapy and even invasive procedures are largely ineffective.

Specifically, Persica’s novel antibiotic treatment is targeted at CLBP patients that have easily identifiable changes to their spine as seen on MRI scans, termed Modic 1 and mixed Modic 1-2 changes/bone oedema (swelling). These changes have been shown to be present in approximately 6% of the general public and 20% of the CLBP population [1].

The treatment, based on the groundbreaking clinical research led by Albert and Manniche which demonstrated the link between CLBP and bacterial infection [2], is a minimally invasive injection of antibiotic formulation directly to the site of infection. The direct delivery method, low dose and short course of treatment offers means of minimising side-effects of prolonged oral antibiotic therapy and ensures that the treatment does not exacerbate the growing problem of antibiotic resistance.

CLBP is the world’s leading cause of disability and the associated costs to society, including treatment, time off work and disability pensions, are estimated to be £12-15 billion per annum in the UK and approximately $100 billion per annum in the USA. Similar findings have been reported in most advanced countries [3,4,5,6].
