SAN DIEGO, June 05, 2019 (GLOBE NEWSWIRE) -- Scilex Holding Company (Scilex), a majority-owned subsidiary of Sorrento Therapeutics, Inc. (Nasdaq: SRNE), announces the completion of post-merger integration.

Following the merger with Semnur Pharmaceuticals, Inc. in March 2019, and the contribution of Scilex Pharmaceuticals Inc. equity to Scilex Holding Company, Scilex rapidly proceeded to implement key changes necessary to ensure the long-term success of the newly formed company.

  • Right-sized corporate management team. New senior executive team benefits from significant drug commercialization experience. New focus on operational excellence in support of commercial launch of ZTlido® (lidocaine topical system) 1.8%.
  • Realigned sales territories to maximize growth in high potential areas. Reduced overall sales related expenses by over 20% without any expected negative impact to field operation performance and enabled better targeting of addressable markets. Gross sales in the past three months have shown strong and sustained month-over-month growth, increasing from approximately $1 million in March, to $2.4 million in April and $3.3 million in May, respectively.
  • Reprioritized drug development pipeline. 1) SP-102 phase 3 clinical trial remains on track to be completed by first half of 2020. 2) The 5.4% (3X strength) lidocaine topical system is being evaluated for a lower back pain indication in an upcoming phase 2 trial expected to start in the second half of 2019.

Jaisim Shah, Chief Executive Officer and President of Scilex, commented, “We are very pleased with the rapid progress made to reorient the company to ensure focus on key areas post-merger. We now have in place the full senior executive team complemented by an outstanding team of field sales reps and managed care access managers, who are deeply knowledgeable reimbursement experts. Leading Global venture capital firms including Canaan Partners, Frazier Healthcare Partners, and Vivo Capital, are shareholders in Scilex along with Sorrento and Japan’s Itochu Corporation, a $100 billion Fortune Global 20 company. With the ongoing opioid crisis in our nation, Scilex has been in active dialogues with local, state and federal agencies on best strategies and methods to treat a continuum of chronic and acute pain conditions using non-addictive non-opioid therapies. Scilex can take full advantage of the opportunities created in this paradigm shift.”

About ZTlido® (lidocaine topical system) 1.8%

Indication ZTLIDO is indicated for relief of pain associated with post-herpetic neuralgia (PHN).

Important Safety Information

Contraindications ZTLIDO is contraindicated in patients with a known history of sensitivity to local anesthetics of the amide type, or to any other component of the product.

Warnings and Precautions Accidental exposure can occur even after a ZTLIDO patch has been used. Small children or pets could suffer serious adverse effects from chewing or ingesting a new or used ZTLIDO patch.  Store and dispose of patches properly and keep out of reach of children and pets.

Excessive dosing or overexposure to lidocaine can occur. Longer duration of application, application of more than the recommended number of patches, smaller patients, or impaired elimination may all contribute to increased blood concentration levels of lidocaine.  If lidocaine overdose is suspected, check drug blood concentration. Management of overdose includes close monitoring, supportive care, and symptomatic treatment.

Cases of methemoglobinemia have been reported with local anesthetic use, although patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, or concurrent exposure to oxidizing agents or their metabolites are more susceptible to developing clinical manifestations of the condition.  Signs and symptoms include cyanotic skin discoloration and/or abnormal coloration of the blood and may occur immediately or may be delayed after exposure.  Methemoglobin levels may continue to rise leading to more serious central nervous system and cardiovascular adverse effects.  Discontinue ZTLIDO and any other oxidizing agents.  Depending on severity of the symptoms, patients may respond to supportive care or may require treatment with methylene blue, exchange transfusion, or hyperbaric oxygen.

Application site reactions can occur during or immediately after treatment with ZTLIDO. This may include development of blisters, bruising, burning sensation, depigmentation, dermatitis, discoloration, edema, erythema, exfoliation, irritation, papules, petechia, pruritus, vesicles, or may be the locus of abnormal sensation. These reactions are generally mild and transient, resolving spontaneously within a few minutes to hours. Inform patients of these potential reactions and that severe skin irritation may occur with ZTLIDO if applied for a longer period than instructed.

Hypersensitivity cross-reactions may be possible for patients allergic to PABA derivatives.  Manage hypersensitivity reactions by conventional means.

Eye exposure with ZTLIDO should be avoided. If eye contact occurs, immediately wash out the eye with water or saline and protect the eye (such as, eye glasses/eye wear) until sensation returns.

Adverse Reactions Side effects of ZTLIDO include application site reactions such as, irritation, erythema, and pruritus. These are not all of the adverse reactions that may occur.  Please see Full Prescribing Information for more information.

Use in Specific Populations Use of ZTLIDO during lactation should be used with caution as lidocaine is excreted into breast milk.  The limited human data with lidocaine in pregnant woman is not sufficient to inform drug-associated risk for major birth defects and miscarriage.
