Scilex Announces the Availability of ZTlido™

SAN DIEGO, Oct. 01, 2018 (GLOBE NEWSWIRE) — Scilex Pharmaceuticals Inc. (Scilex), a subsidiary of Sorrento Therapeutics, Inc. (NASDAQ: SRNE) (Sorrento), announced that ZTlido™ (lidocaine topical system) 1.8% (ZTLIDO) is now commercially available.  ZTLIDO will be shipped to wholesalers and is anticipated to be available by prescription at retail pharmacies across the U.S. by the end of this week, thus commencing a full U.S. launch.

“Today marks a significant organizational milestone as Scilex transitions to a commercial entity with the launch of ZTLIDO,” said George Ng, President, Business, of Scilex.  “We are pleased to introduce a non-opioid, first line alternative and option for patients with post-herpetic neuralgia, and with the recent $140 million, non-dilutive raise and commercial infrastructure we have built, we believe we have the resources and tools to support the launch and commercialization of ZTLIDO.”

Scilex has entered into an agreement with Syneos Health (formerly, Inventiv Health) to support the launch and commercialization of ZTLIDO in the U.S.  ZTLIDO is supported by an experienced, field sales team of over a hundred sales representatives, as well as Medical Science Liaison (MSL), market access and trade teams.

ZTLIDO is a topical product that uses an advanced adhesion technology providing more efficient lidocaine delivery than Lidoderm® over a full 12 hours. Post-herpetic neuralgia (PHN), also referred to as post-shingles pain, is a frequent complication of shingles, a condition caused by the herpes zoster (HZ) virus which afflicts an estimated 1 million people each year in the US.

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.

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 (eg, 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 women are not sufficient to inform drug-associated risk for major birth defects and miscarriage.
