SCLX Scilex Holding Company

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 and, following the formation of its proposed joint venture with IPMC Company, in neurodegenerative and cardiometabolic disease, today announced that it has entered into an amendment (the “Amendment”) to its existing license agreement with Romeg Therapeutics, LLC (“Romeg”), entered into in June 2022, for ex-US rights to Gloperba®. Romeg had previously granted Scilex an exclusive license to commercialize Gloperba® only in the U.S.   

Gloperba® is taken orally like cough syrup. The dosage of 0.6mg per 5ml (teaspoon) can fill that important void in treatment where patients may have difficulty swallowing pills. It can also provide more adjustable dosing, titration and dose-reduction options in specific populations, especially for gout patients with renal or hepatic impairment and reduce side effects with the goal to improve patient convenience and disease management.

According to Nature Reviews Rheumatology, gout is a common chronic crystal deposition disorder that affects between <1% and 6.8% of the population, depending on the population studied.   Both prevalence and incidence of gout seem to be rising across the globe.   Management of gout continues to be poor, with fewer than one-half of patients receiving definitive ‘curative’ urate-lowering therapy.   Adherence to urate-lowering therapy is often poor and rates of non-persistence are high.   Obesity and comorbidities are important risk factors for gout and are important drivers of its rising prevalence and incidence (https://www.nature.com/articles/s41584-020-0441-1).

Scilex’s commercial products include: (i) ZTlido® (lidocaine topical system) 1.8%, a prescription lidocaine topical product approved by the U.S. Food and Drug Administration (the “FDA”) for the relief of neuropathic pain associated with postherpetic neuralgia, which is a form of post-shingles nerve pain; (ii) ELYXYB®, a potential 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; and (iii) Gloperba®, the first and only liquid oral version of the anti-gout medicine colchicine indicated for the prophylaxis of painful gout flares in adults.

In addition, Scilex has three product candidates: (i) SP-102 (10 mg, dexamethasone sodium phosphate viscous gel) (“SEMDEXA” or “SP-102”), a novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica, for which Scilex has completed a Phase 3 study and was granted Fast Track status from the FDA in 2017; (ii) SP-103 (lidocaine topical system) 5.4%, (“SP-103”), a next-generation, triple-strength formulation of ZTlido, for the treatment of acute pain and for which Scilex has recently completed a Phase 2 trial in acute low back pain. SP-103 has been granted Fast Track status from the FDA in low back pain; and (iii) SP-104 (4.5 mg, low-dose naltrexone hydrochloride delayed-release capsules) (“SP-104”), a novel low-dose delayed-release naltrexone hydrochloride being developed for the treatment of fibromyalgia, for which Phase 1 trials were completed in the second quarter of 2022.
