SAN DIEGO, June 6, 2013 /PRNewswire/ -- Sorrento Therapeutics, Inc. (OTCBB: SRNE) today announced that it has been awarded the 2013 Frost & Sullivan Global Investment Opportunity Award in Oncology.

In the citation for the 2013 Global Investment Opportunity Award in Oncology, Frost & Sullivan highlights Sorrento's diverse G-MAB® library technology, the experienced management team, and its ability to select and rapidly develop promising drug candidates, such as the late-stage oncolytic product candidate Cynviloq™—a next-generation branded paclitaxel formulation to be exclusively marketed and distributed by IGDRASOL, Inc. in the U.S. and 27 EU countries, if approved—and fully human anti-PD-L1 and anti-PD-1 monoclonal antibodies (mAbs) in oncology. Sorrento has the right to acquire IGDRASOL pursuant to a previously announced option agreement, entered into in March 2013. Taken together, these unique characteristics make "Sorrento Therapeutics the rightful recipient of the 2013 Frost & Sullivan Global Investment Opportunity Award" as the award report concludes.

"We are honored that the distinguished and independent global analyst firm Frost & Sullivan has recognized our achievements as well as our potential, and emphasizes the value our technologies and expertise have created," said Henry Ji, Ph.D., Sorrento's president and CEO. "We believe this award validates our corporate strategy. We are rapidly moving forward to develop our lead product candidates, including Cynviloq™ and our fully human antibody drug candidates targeting PD-L1 and PD-1, which we believe are very promising and exciting targets in the fast-growing market of immunomodulatory cancer therapy."
