Scilex Holding Company (Nasdaq: SCLX, “Scilex” or the “Company”) today announced the publication of results of the pivotal registration trial of SP-102 (SEMDEXA™) in PAIN, the official journal of the International Association for the Study of Pain, which features original research on the nature, mechanisms and treatment of pain.
- The Phase 3 study results are being published in PAIN® Journal, which is the leading journal devoted to pain medicine and research. PAIN is the official journal of the International Association for the Study of Pain, and features original research on the nature, mechanisms and treatment of pain.
- This Phase 3 study met primary and important key secondary endpoints, with SP-102 (SEMDEXA™) treatment, decreasing pain intensity for over a month in sciatica patients and resulting in statistically significant and clinically meaningful improvement in the disability index score while maintaining safety comparable to placebo.
- This Phase 3 topline data result was presented at the American Society of Interventional Pain (ASIPP) conference in Las Vegas in May 2022 in an oral presentation by Dr. Nebojsa Nick Knezevic, M.D., Ph.D., Professor of Anesthesiology and Surgery, College of Medicine, University of Illinois at Chicago, President of the Illinois Society of Interventional Pain Physicians, Director-at-Large of the North American Society of Neuromodulation, Vice-Chair for Research and Education, Advocate Illinois Masonic Medical Center, Department of Anesthesiology and Pain Management.
- This Phase 3 study represents a potential significant improvement in treatment of adult patients with lumbosacral radicular pain (sciatica), who struggle with the clinical consequences of no currently FDA approved therapies, suboptimal formulations of corticosteroids used off-label and/or excess pain and disability.
- SP-102 (SEMDEXA™) was granted Fast Track status from the FDA in 2017.
PALO ALTO, Calif., June 14, 2024 (GLOBE NEWSWIRE) -- Scilex Holding Company (Nasdaq: SCLX, “Scilex” or the “Company”), an innovative revenue-generating company focused on acquiring, developing and commercializing non-opioid pain management products for the treatment of acute and chronic pain, today announced the publication of results of the pivotal registration trial of SP-102 (SEMDEXA™) in PAIN, the official journal of the International Association for the Study of Pain, which features original research on the nature, mechanisms and treatment of pain.
SP-102 (SEMDEXA™) is a novel injectable corticosteroid gel formulation product in development for the treatment of lumbosacral radicular pain, which contains no preservatives, surfactants, solvents, or particulates.
The C.L.E.A.R. Trial (Corticosteroid Lumbosacral Epidural Analgesia for Radiculopathy) was designed to investigate safety and analgesic effects of a single and repeat transforaminal injections of SP-102 (SEMDEXA™) compared to placebo (saline injection). The trial enrolled 401 low back pain subjects with unilateral intervertebral lumbar disc herniation, resulting in radicular pain symptoms of moderate to severe leg pain. It is the largest known randomized well-controlled trial in sciatica using epidural steroid injections.
The trial met its primary and important key secondary endpoints with statistical significance, demonstrating clinically meaningful reduction of pain, improvement in disability and functional outcomes.
Safety analysis demonstrated a clean safety profile with no identified safety risks. There were no serious adverse events related to the drug or injection procedure, and no adverse events of special interest reported, such as hematoma and infection at the injection site, or paraplegia. By contrast, these events are associated with the off-label use of non-approved steroid preparations. The C.L.E.A.R trial also established safety of repeat injections, as patients who experienced moderate-to-severe radicular pain between 4 and 23 weeks following initial injection were allowed to receive an open-label additional SP-102 (SEMDEXA™) injection. The safety analysis was comparable between treatment groups through 4, 12 and 24 weeks of the study period.
“I am very glad to be involved in the C.L.E.A.R. trial, having first-hand experience with SP-102 (SEMDEXA™), pain management medication with extended local effect. Currently, we have to use steroid formulations developed for other uses, which are unapproved for epidural administration. If SP-102 (SEMDEXA™) is approved by the FDA, it would be the first corticosteroid ever approved for epidural injections, addressing safety issues with current formulations. This could be an important addition to treatment options for patients with lumbosacral radicular pain,” said Alan Miller, M.D., Principal Investigator from Coastal Clinical Research Specialists, Jacksonville, Florida, primary author of the publication.
