Abstract
Introduction: Chronic low back pain (CLBP) affects over half a billion people worldwide. Current pharmacologic treatments, comprising mainly non-steroidal anti-inflammatory drugs and opioids, offer limited efficacy and pose significant risks, warranting the development of tolerable, safe and effective alternatives.
Methods: This randomized controlled trial on adults with CLBP was designed to confirm the superior efficacy and gastrointestinal tolerability of VER-01, a novel, standardized full-spectrum extract from Cannabis sativa DKJ127 L., over opioids. Subjects were randomized (1:1) to receive VER-01 or a range of commercially available opioids. After a 3-week titration, subjects underwent 24 weeks of treatment, followed by 2 weeks of wash-out. The primary endpoint was the relative risk of constipation occurrence after 27 weeks treatment. Secondary endpoints included changes in pain and sleep scores, determined using an 11-point numeric rating scale (NRS), with key secondary endpoints defined for week 27.
Results: A total of 384 individuals were randomized to receive VER-01 (n = 192) or opioids (n = 192). Subjects receiving VER-01 were fourfold less likely to develop constipation than those receiving opioids (relative risk [RR] VER-01/opioids 0.25; 95% confidence interval [CI] 0.09-0.69; p = 0.007) and threefold less likely to use laxatives (RR 0.34; 95% CI 0.18-0.65; p < 0.001). Longitudinal analysis revealed that VER-01 was superior to opioids in terms of pain reduction over 6 months of treatment, although differences in secondary endpoints limited to week 27 alone were not significant. Throughout the 6 months of treatment, mean pain reduction was 2.50 NRS points with VER-01 versus 2.16 with opioids (mean difference [MD] 0.34; 95% CI 0.00-0.67; p = 0.048), and sleep improved by 2.52 points with VER-01 versus 2.07 with opioids (MD 0.45; 95% CI 0.11-0.79; p = 0.009). These benefits were particularly pronounced in participants with severe pain, with greater pain reduction (MD 0.58; 95% CI 0.01-1.15) and sleep improvement (MD 0.66, 95% CI 0.05-1.27) compared to opioids.
Conclusions: VER-01 demonstrated superiority over opioids in treating CLBP, both in terms of efficacy and gastrointestinal tolerability.
期刊介绍：
Pain and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of pain therapies and pain-related devices. Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, acute pain, cancer pain, chronic pain, headache and migraine, neuropathic pain, opioids, palliative care and pain ethics, peri- and post-operative pain as well as rheumatic pain and fibromyalgia.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports, trial protocols, short communications such as commentaries and editorials, and letters. The journal is read by a global audience and receives submissions from around the world. Pain and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
