Press Release


SAN DIEGO, November 14th, 2017 /GlobalNewswire/ — Sorrento Therapeutics, Inc. (NASDAQ: SRNE) (“Sorrento”), announced today that Scilex Pharmaceuticals Inc. (“Scilex”), a majority-owned subsidiary of Sorrento, filed the European Marketing Authorization Application (MAA) for its lead product candidate, ZTlido™ (lidocaine medicated plaster 1.8%), through a hybrid regulatory pathway with the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (UK).

ZTlido™ was specifically designed to efficiently deliver lidocaine and have superior adhesion as compared to the US and EU reference products, Lidoderm®/ Versatis® respectively, in recognition that adhesion is critical to the safety, efficacy and quality of a patch or medicated plaster pharmaceutical product.  This is especially the case for patch or medicated plaster systems such as ZTlido™, where the drug is contained in the adhesive and must be in contact with the skin to deliver the drug.

The UK will be the reference member state, or lead review agency, with corresponding filings in multiple other countries including Germany, France, Spain, Italy and Ireland.

The review time for the MAA is 210 days with clock stops for information requests from agencies. Scilex expects to have a decision in the 4th quarter of 2018.

The company is currently evaluating commercial options and partnerships for the EU, with a potential commercial launch date for Europe in 2019.

Scilex currently has a new drug application under review with the FDA in the US for ZTlido™.
