Insights
The recent publication in Anesthesiology Journal regarding Scilex Holding Company's study on ZTlido® for chronic neck pain could represent a significant development in the non-opioid pain management market. The clinical benefit trend observed in the study, despite the limitations of early termination and sample size, suggests a potential for the product to address a substantial unmet need within the adult population suffering from neck pain. The topical medication market, projected to grow to $7.3 billion by 2031, indicates a lucrative opportunity for Scilex if ZTlido® or its triple-strength counterpart, SP-103, gains FDA approval.
From a research perspective, the study's insights into the patient population responsive to topical lidocaine and the safety profile of ZTlido® are crucial for designing future trials. The potential Phase 3 trial for SP-103 will be pivotal in determining the product's efficacy and market viability. Investors should monitor these developments closely, as positive trial outcomes could lead to significant market share in the pain management sector for Scilex.
The economic implications of Scilex's research into ZTlido® for neck pain are multifaceted. Given the high prevalence of neck pain and its impact on work absences, an effective treatment could lead to substantial cost savings in terms of reduced disability and healthcare expenses. The U.S. low back and neck pain market, estimated at $134.5 billion, underscores the economic burden of these conditions. A non-addictive, effective treatment could disrupt this market significantly.
Furthermore, the shift towards non-opioid treatments due to the opioid crisis enhances the potential market value of ZTlido®. Investors should consider the long-term cost-benefit ratio of such treatments and the potential for Scilex to capitalize on policy shifts favoring non-opioid therapies.
The data presented on ZTlido® suggests a competitive edge in the topical analgesic market, particularly if the triple-strength SP-103 formulation can demonstrate superior efficacy and skin penetration. Scilex's strategic positioning to become the first to market with an FDA-approved treatment for neck pain could create a strong foothold and drive investor interest. The company's focus on non-opioid pain management aligns with current industry trends towards safer pain management options.
However, investors should be cautious and consider the risks associated with the drug development process, regulatory hurdles and market acceptance. The potential for Scilex's growth hinges on successful Phase 3 trials and subsequent FDA approval. The implications for the stock market will likely be tied to these milestones and the company's ability to effectively commercialize the product.
- The lifetime prevalence of neck pain in the adult population is estimated to range from
14.2% to71% with a mean of48.5% .2 There are currently no approved medical treatments for neck pain in the U.S. - The study was a randomized, double-blind, placebo-controlled crossover trial performed at four U.S. military, Veterans Administration, academic, and private practice sites, in which 76 patients were randomized to receive either a placebo patch followed by ZTlido® for 4-week intervals or vice versa.
- Overall, separation between ZTlido® and placebo effects and variability observed in this patient population provided necessary estimates for planning a potential Phase 3 development trial of SP-103 (triple-strength formulation of ZTlido®) which contains 3-times higher concentration of lidocaine and has completed a Phase 2 trial in acute back pain.
PALO ALTO, Calif., Feb. 20, 2024 (GLOBE NEWSWIRE) -- Scilex Holding Company (Nasdaq: SCLX, “Scilex” or “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 publication in Anesthesiology Journal of results from an investigator-initiated research study using ZTlido® for the treatment of chronic neck pain.

Overall, separation between ZTlido® and placebo effects and variability observed in this patient population provided necessary estimates for planning a potential Phase 3 development trial of SP-103 (triple-strength formulation of ZTlido®), which contains 3-times higher concentration of lidocaine. Additionally, this study provided essential insight into selection of patient population responsive to topical lidocaine treatment. Application of ZTlido® was well-tolerated and safety profile consistent with other ZTlido® trials previously conducted by Scilex.
“Given the strong signal for clinically meaningful efficacy, our study results point to a potential necessity of further investigation of topical lidocaine treatment, especially in a formulation that contain higher dose and greater skin penetration than currently available alternatives, as it may provide greater clinical benefit to patients with chronic neck pain,” said Principal Investigator, Dr. Steven P. Cohen, Chief of Pain Medicine and Professor of Anesthesiology & Critical Care Medicine, Neurology, Physical Medicine & Rehabilitation, and Psychiatry & Behavioral Sciences at the Johns Hopkins School of Medicine, and Professor of Anesthesiology and Physical Medicine & Rehabilitation at Walter Reed National Military Medical Center, Uniformed Services University of the Health Sciences.
“This proof-of-principle study data using ZTlido® in addition to our recently published skin penetration data demonstrating passive diffusion of lidocaine from SP-103 into a muscle layer, provide support for our strategy to pursue chronic neck pain indication for our next generation topical lidocaine system, aiming to become the first therapy approved for such common medical condition with significant unmet need for safe and effective non-addictive treatment,” said Dmitri Lissin, M.D., Chief Medical Officer of Scilex.
