Brief Summary:
This is a research study to find out if Qutenza 8 capsaicin topical system is safe and effective when treating subjects with lower back pain LBP that is caused by damage at or near the nerves root in the lower back leg lumbosacral radiculopathy which is pain that can move all the way down the back of the leg The pain may also start outside of the spinal cord in the peripheral nerves and may also be felt all the way down the back of the leg neuropathic LBP Qutenza 8 capsaicin the study drug is currently FDA approved to treat nerve pain after a shingles outbreak in addition to a type of nerve pain in the feet associated with diabetes In this study a maximum of four patches per visit sized 14cm x 20 cm will be used to deliver the Qutenza 8 capsaicin to the participants skin
If a subject meets the qualifications for this study in addition to their standard of care for their LBP they can expect to have a total of 5 visits in a 12 month period Each visit will require subjects to fill out several surveys and receive treatment patches for their LBP your doctor will decide if participants will need to be retreated at each visit based on your symptoms The study visits are estimated to take 90 minutes upwards to 120 minutes

Detailed Description:
Chronic lower back pain LBP and lumbosacral radiculopathy are common disabling and costly conditions The lifetime prevalence of LBP is estimated to be greater than 70 in industrialized countries with a 1-year prevalence of 15-45 and LBP is the most common cause of years lived with disability worldwide Chronic LBP defined as LBP lasting less than 3 months is a complex and heterogeneous condition with nociceptive and neuropathic components
The goals of treatment of chronic LBP and lumbosacral radiculopathy are to reduce pain maintain function and prevent future exacerbation Guidelines advocate for a multimodal approach to the management of these conditions combining pharmacological therapies for symptomatic relief with nonpharmacological approaches such as physical rehabilitation Choice of treatment is individualized according to the nature and severity of symptoms the presence of comorbid conditions potential for adverse effects and drug interactions and cost At this time there are no specific recommendations for treatment of the neuropathic components of chronic LBP and neuropathic pain medications for painful radiculopathy have limited response rates Furthermore current pharmacologic approaches for the treatment of neuropathic pain are associated with a risk of significant adverse effects which can have a serious impact on patients quality of life As such there is a pressing need for safe and effective therapeutic options in treating neuropathic LBP and painful lumbosacral radiculopathy
Capsaicin is the main compound in chili peppers and acts mechanistically as a selective agonist of the transient receptor potential vanilloid 1 TRPV1 channel which is highly expressed on nociceptors High concentrations of capsaicin have been effectively utilized for the treatment of neuropathic pain Additionally whereas many pharmacologic and interventional pain relief options for chronic LBP and radiculopathy cause weight gain capsaicin has been widely studied for its weight loss potential
Emerging evidence suggests the use of topical capsaicin may be a safe and efficacious treatment for chronic LBP and radiculopathy With regards to LBP a 2010 double-blind multi-center randomized clinical trial on the use of 005 topical capsaicin cream for the treatment of chronic LBP demonstrated a significantly higher number of patients experiencing at least 50 pain sum score improvement at 3 weeks compared to placebo A 2016 open-label study of 90 patients with lumbosacral neuropathic pain who received treatment with a topical 8 capsaicin patch found statistically significant reductions in pain at 2 8 and 12 weeks follow-up With regards to lumbosacral radiculopathy a 2017 randomized controlled trial of 50 participants with chronic lumbosacral radiculopathy treated with a topical 8 capsaicin patch found at least a 30 improvement of pain in 714 and 391 of patients with 3 months to 2 years duration of pain and greater than 2 years duration of pain respectively A prospective study investigating the use of a single 8 capsaicin patch in patients with a variety of neuropathic pain conditions including radiculopathy noted that the proportions of patients achieving a 30 and 50 decrease in pain at 12 weeks were 43 and 24 respectively Additionally a small retrospective analysis of patients with painful radiculopathy found that the capsaicin 8 patch provided rapid and sustained pain relief with a significant reduction in prescribed concomitant pain medications In brief the current literature is limited by small sample sizes and short follow up periods but does suggest topical capsaicin is a rational choice for the treatment of neuropathic lumbosacral pain
The neuropathic components in chronic LBP and lumbosacral radiculopathy may be under-recognized and therefore undertreated Most clinical trials of drug treatments for neuropathic pain have examined patients with Postherpetic neuralgia or painful diabetic peripheral neuropathy and the extent to which results of these studies can be extrapolated to other neuropathic conditions is unknown Use of the Qutenza 8 capsaicin topical patch for the treatment of chronic LBP and lumbosacral radiculopathy holds great promise to improve the pain and function of patients suffering with these common and debilitating conditions which in turn has the potential for tremendous economic impact
