San Diego, CA – February 10, 2014 Sorrento Therapeutics, Inc. (NASDAQ: SRNE; Sorrento), a late-stage clinical oncology company developing new treatments for cancer and associated pain, announced today the Company has obtained exclusive rights to Cynviloq™ (marketed as Genexol-PM® in South Korea and other countries) in Australia, Canada and Mexico from Samyang Biopharmaceuticals (“Samyang”), a South Korean corporation. Sorrento already has exclusive rights from Samyang for Cynviloq in the U.S. and the 27 countries of the European Union.

“We have made significant progress carving out the clinical and regulatory path for the Cynviloq program, and we continue to build on the global commercial opportunity for this product,” said Henry Ji, Ph.D., President and Chief Executive Officer of Sorrento. “With these expanded rights, Sorrento now covers the vast majority of its targeted Cynviloq markets”.

About Cynviloq™
Cynviloq (IG-001; a paclitaxel-loaded micellar diblock copolymer) is a next-generation branded paclitaxel formulation for the potential treatment of metastatic breast cancer, non-small cell lung cancer, pancreatic cancer, and other solid tumors. In July 2013, the FDA Division of Oncology Products 1 agreed that the data available are supportive for a 505(b)(2) pathway, using Abraxane® and Taxol® as the Reference Listed Drugs, to pursue approval. Sorrento anticipates initiating a single Bioequivalence trial required for registration, in the first quarter of 2014.
