- Scilex today announced that the U.S. Patent and Trademark Office has allowed numerous claims from U.S. patent application no. 17/562,229 and will issue a new patent containing those claims related to the treatment of acute pain (the “Patent”), to Scilex in late 2024, further strengthening the Company’s intellectual property position and coverage for its acute migraine treatment drug product, ELYXYB®, a liquid, micro-encapsulation formulation of celecoxib.
- ELYXYBTM is a first-line treatment and the only FDA-approved, ready-to-use oral solution for the acute treatment of migraine, with or without aura, in adults.1 The U.S. oral migraine drug market size is estimated to be $1.8 billion in 2022.2
- ELYXYB®, a rapid onset and ready to use formulation of Celecoxib, delivers a first line non-opioid therapeutic alternative to habit-forming opioids and acetaminophen, the leading cause of acute liver failure in the U.S.3
- DelveInsight estimates there were approximately 100 million cases of acute pain in the U.S. and that the total acute pain market in the U.S. was approximately $3 billion in 2021.4
- There is strong evidence for the use of non-steroidal anti-inflammatory drugs (NSAIDs) as a first-line treatment for migraine. ELYXYB® (celecoxib oral solution) is in the same class of agents, is fast acting, and has the potential to have the lowest gastrointestinal (GI) side effects of all NSAIDs.5
PALO ALTO, Calif., Aug. 21, 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 that the U.S. Patent and Trademark Office has allowed numerous claims from U.S. patent application no. 17/562,229 and will issue a new patent containing those claims related to the treatment of acute pain (the “Patent”), to Scilex in late 2024, further strengthening the Company’s intellectual property position and coverage for its acute migraine treatment drug product, ELYXYB®, a liquid, micro-encapsulation formulation of celecoxib. The Patent, titled “Methods of Treating Pain,” covers methods of treating acute pain.
Clinicians in a recent market research study expressed their desire for fast and safe alternatives for two large pools of acute migraine patients – those who have an insufficient response to triptan therapy and those who have contraindications to triptan use. ELYXYB®’s product profile mapped with a high degree of certainty to these stated unmet needs. In clinical studies, patients treated with ELYXYB® demonstrated pain relief in as little as 15 minutes, and significant pain relief compared to placebo within 45 minutes in approximately 50% of patients.6,7
“We are very excited about the potential of ELYXYB® since launching the product in the U.S. in April 2023. This is a highly complementary commercial asset that allows us to provide physicians with another tool in their pain management armamentarium to treat migraines earlier in the patient’s journey. These new patents will provide the ability to file application in the future for acute pain,” said Jaisim Shah, Chief Executive Officer and President of Scilex.
