Scilex Holding Company Announces that ZTlido® Achieves a Major Milestone – Over One Million Patients Treated Since its Launch – and Two Additional Milestones Met

• Over one million patients are estimated to have been treated with ZTlido^® since its launch according to Symphony Health prescription data.
• ZTlido^® is now the number one prescribed non-opioid branded pain medication by pain specialists in the United States, based on Symphony Health prescription data gathered from January 2023 to November 2023.
• Patients report 89% satisfaction with ZTlido^®, in a 2023 patient survey conducted by Scilex (n=100, rating as “completely” or “mostly” satisfied with ZTlido^® treatment).

ZTlido has been strategically designed to address poor adhesion, a leading complaint associated with other currently marketed topical lidocaine products. In clinical studies, the technology behind ZTlido manufacturing provided significantly improved adhesion over Lidoderm^® (a branded, prescription 5% lidocaine patch product) and other generic lidocaine patches at 12 hours after application.  In a head-to-head study of 44 subjects, ZTlido demonstrated statistically significant adhesion at all-time points compared to other lidocaine patches.¹

“We are pleased to learn that an estimated over 1 million patients in the U.S. have been treated with ZTlido^® emphasizing one of the key paradigm shifts in patient care of increasing use of opioid sparing regimens. We strive to continue to support the market’s ongoing migration away from opioid agents in 2024 and lead the way in providing increasing non-opioid pain relief therapeutics with our upcoming third opioid sparing product launch, Gloperba^®”, said Jaisim Shah, Chief Executive Officer and President of Scilex.
