Scilex Holding Company, a Sorrento Company, Announces That the FDA Has Granted Fast Track Designation for SP-103 (Lidocaine Topical System) 5.4%, Next Generation Triple Strength Formulation of ZTlido®, for the Treatment of Acute Low Back Pain (LBP)
SP-103 receives Fast Track Designation, which makes it eligible for some or all of the following:
More frequent meetings or written communication with the FDA to discuss the SP-103 development plan and ensure collection of appropriate data needed to support drug approval.
Eligibility for Accelerated Approval or Priority Review, if relevant criteria are met.
Rolling Review, which means that Scilex can submit completed sections of its New Drug Application (NDA) for review by the FDA, rather than waiting until every section of the NDA is completed before the entire application can be reviewed.
Despite an overall lack of evidence to support their efficacy, opioids continue to be prescribed to treat acute LBP when patients seek medical evaluation.
According to the CDC in 2020, LBP was the most common type of pain reported by patients, with 25% of U.S. adults reporting LBP in the prior 3 months.1
LBP is estimated to have a total potential global market opportunity of approximately $10.0 billion by 2026.2
PALO ALTO, Calif., Aug. 30, 2022 (GLOBE NEWSWIRE) -- Scilex Holding Company (“Scilex”), a commercial biopharmaceutical company focused on developing and commercializing non-opioid therapies for patients with acute and chronic pain, today announced that FDA has granted fast track designation for its investigational drug and device product candidate, SP-103. Scilex is a nearly 100% (or over 99.9%) majority-owned subsidiary of Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”).
Scilex is developing SP-103 to be a non-opioid triple-strength, non-aqueous lidocaine topical system for the treatment of acute LBP. If approved, SP-103 could become the first FDA-approved lidocaine topical product for the treatment of acute LBP. Acute LBP can range in intensity from a dull, constant ache to a sudden, sharp sensation that leaves the person incapacitated. According to the CDC in 2020, LBP was the most common type of pain reported by patients, with 25% of U.S. adults reporting LBP in the prior 3 months1. LBP is estimated to have a total potential global market opportunity of approximately $10.0 billion by 2026.2
“We are pleased that the FDA has granted Fast Track Designation for SP-103,” said Dr. Dmitri Lissin, Chief Medical Officer of Scilex. “The FDA's decision to place SP-103 in a category that may enable expedited development and review is an important milestone for Scilex.”
There are currently no approved pharmaceutical treatments specifically indicated for the treatment of acute LBP. The market Scilex intends to address with SP-103, if approved, includes etiologies that are currently treated with non-procedural or non-surgical interventions, and where available treatments provide inadequate pain relief or result in unacceptable adverse effects. These treatments may include NSAIDs, antidepressants and opioids, as well as off-label use of lidocaine patches.
“We are very pleased that the FDA has granted Fast Track designation for the non-opioid SP-103 program, the next generation triple strength formulation of ZTlido®,” said Jaisim Shah, President and Chief Executive Officer of Scilex. There are currently very limited approved treatment options for acute low back pain, a serious condition the prevalence of which continues to rise, leaving this affected group with very limited safe and effective treatment options to date. Receiving this designation underscores the potential of the ZTlido® platform and the need for a new therapy like SP-103 that may improve outcomes for those with this serious debilitating condition.”
The safe and effective treatment of acute LBP represents high unmet needs and creates a large market opportunity. LBP is one of the costliest musculoskeletal conditions in industrialized countries. Experts have estimated that approximately 80% of Americans will experience LBP during their lifetime. The annual prevalence of LBP is 15% to 45% with a point prevalence of approximately 30% in the United States. Sixty percent of those who suffer from acute LBP recover in six weeks and up to 80-90% recover within 12 weeks. However, the recovery of the remaining patients with LBP is less certain. LBP accounts for 19% of all workers’ compensation claims in the United States.3 Americans spent at least $135 billion in 2016 on treating low back and neck pain, which was the highest expenditure among 154 conditions studied by the Department of the Institute for Health Metrics and Evaluation at the University of Washington.4
Scilex’s triple-strength SP-103 is an investigational, non-aqueous lidocaine topical system undergoing clinical development in acute LBP conditions. SP-103 builds on the learnings from Scilex’s FDA-approved product, ZTlido® (topical lidocaine system) 1.8%, because both products share the same adhesive drug delivery formulation and manufacturing technology. Scilex believes that, if approved, SP-103 could become the first FDA-approved lidocaine topical product for acute LBP indications. All current uses of topical lidocaine products for acute LBP are off-label. SP-103 has three times the drug load of ZTlido® (108 mg versus 36 mg) in the same adhesive system to potentially deliver a three-fold level of the drug within a targeted area, but retaining the convenience of a single topical system. Additionally, SP-103 is designed to deliver a localized dose of lidocaine that is three times greater than any lidocaine topical product that Scilex is aware of either on the market or in development. Scilex believes that, if approved, SP-103 may be able to address the limitations of prescription lidocaine patches in treating acute LBP by delivering a higher dose of lidocaine to the application site. As part of the lifecycle management, Scilex will also target localized musculoskeletal pain, acute and chronic pain conditions, and post-operation pain management, to focus on developing and commercializing non-opioid therapies for patients with acute and chronic pain. Scilex expects to complete its current Phase 2 trial of SP-103, randomized, double-blind, placebo controlled, parallel group, multicenter study to evaluate the safety and efficacy in subjects with acute lower back pain (LBP) in 10 U.S. sites, in Q1-2023. The outcome should enable planning of subsequent Phase 3 trial(s).

Under Section 561A(f)(2) of the United States Federal Food, Drug, and Cosmetic Act, Scilex is required to make our expanded access policy for SP-103 (lidocaine topical system) 5.4% publicly available by September 10, 2022 (within 15 days of the signature date of the FDA Fast Track letter).
Scilex Holding Company and Vickers Vantage Corp. I (Nasdaq: VCKA) (“Vickers”), a special purpose acquisition company sponsored by Vickers Venture Fund VI Pte Ltd and Vickers Venture Fund VI (Plan) Pte Ltd, have entered into a definitive business combination agreement ("BCA") on March 17, 2022. Upon the closing of the transaction, the combined company (the “Combined Company”) will be renamed Scilex Holding Company, and its common stock and warrants to purchase common stock are expected to be listed on Nasdaq under the ticker symbol “SCLX” and “SCLXW”, respectively. The boards of directors of each of Vickers, Scilex and Sorrento have unanimously approved the proposed transaction. The closing of the transaction, which is expected to occur in the third quarter or early fourth quarter of 2022, is subject to the approval of Vickers’s and Scilex’s shareholders and the satisfaction or waiver of certain other customary closing conditions.
