103 active trials for Chronic Low Back Pain

Comparison of Continuous and Burst High Frequency Spinal Cord Stimulation Paradigms

Spinal cord stimulation (SCS) delivered at 10kHz frequency (HF10 Therapy) has demonstrated superiority to traditional SCS for leg and back pain. Intermittent dosing (ID) refers to the cycling of stimulation, in which there is a designated time period of stimulation being active (ON) and inactive (OFF). Previous studies have demonstrated the safe and effective use of intermittent dosing. However, there still remains a paucity of clinical data on the use of intermittent dosing and which doses (i.e. on/off cycle time periods) are most effective. Furthermore, no previous studies have utilized HF10 therapy when evaluating intermittent dosing. Patients with chronic back and/or leg pain who have undergone permanent spinal cord stimulator implantation delivered by the Nevro Omnia Neurostimulation System and who are reporting decreased efficacy of continuous HF10 therapy will be randomized into one of two treatments: 1) Intermittent Dosing therapy at 30 seconds ON, 90 seconds OFF 2)Intermittent Dosing therapy at 30 seconds ON, 360 seconds OFF. After randomization, each consented subject will present to clinic at which time will first be seen by a team of investigators, sub-investigators, and/or study staff. After evaluation and collection of baseline data, a clinical specialist for the Nevro Omnia Neurostimulation system will program the subject's SCS system according to the treatment group to which they have been randomized, under direct physician supervision Patient's will be seen and evaluated prior to randomization, and thereafter at 2, 4 and 6 weeks. At the 6-week time period, patients will be crossed over to the other study arm and thereafter evaluated at 2, 4 and 6 weeks. As our primary endpoint, we hypothesize that ID HF10 therapy will provide non-inferior pain relief as measured by VAS scores when compared to continuous HF10 therapy. Other endpoints include: charging frequency, EQ-5D scores of wellbeing; PROMIS score for physical function, pain interference, sleep disturbance, and emotional distress; chronic pain acceptance questionnaire 8 (CPAQ-8), patient satisfaction scores, and patient global impression of change

Strategies to Assist With Management of Pain

Chronic low back pain (CLBP) has no known effective treatment. While often treated with long-term opioid therapy, opioids do not work well for many patients and can cause serious side effects, including addiction, poorer mental health, and overdose death. Even when paired with a standard-of-care cognitive behavioral therapy (CBT), results are limited. Patients, families and clinicians are very interested in using alternative treatments for CLBP, especially complementary and integrative treatments such as mindfulness meditation (MM). MM helps train the mind to bring non-judgmental and accepting attention to present-moment experiences such as pain. MM offers an active and safe self-care approach to chronic pain that contrasts with the passive and potentially harmful nature of opioid treatment, and may prove more effective than CBT in helping improve health and well-being, and reduce reliance on opioids in adults with opioid-treated CLBP. Although this hypothesis is supported by early research, including a pilot study by the Principal Investigator, evidence on MM's effectiveness in this population is inconclusive, presenting a critical knowledge gap. With input from patients, family members, and clinicians, the Investigators have designed a study to address this gap and propose a clinical trial that will compare the effectiveness of MM to standard-of-care CBT in opioid-treated CLBP. Based on the existing research, it is hypothesized that MM training will lead to a larger reduction in pain intensity, increase in physical function, improvement in quality of life, and decrease in daily opioid dose, as compared to CBT training, with benefits of MM especially notable in adults with worse mood, anxiety or unhealthy opioid-use behaviors who often experience more severe symptoms of CLBP and less improvement in response to existing therapies. To test these hypotheses, 766 adults with opioid-treated CLBP will be randomly assigned into one of two 8-week treatment groups: MM (383 participants) that will receive the MM training or CBT (383 participants) that will receive the CBT training. Due to the COVID-19 pandemic-related restrictions, the study protocol was modified in October 2020 so that the study can be completed virtually. The effectiveness of MM versus CBT will be assessed over a 12-month period with patient-reported measures, recommended by experts and endorsed by our stakeholder partners, including patients with opioid-treated CLBP, their families and clinicians.
