IGDRASOL to present updates on Cynviloq at AACR annual meeting

Apr 1 2013

Sorrento Therapeutics, Inc. ("STI"; SRNE) and IGDRASOL announced today that IGDRASOL will be presenting updates of its development of Cynviloq™ (IG-001) at the annual meeting of the American Association for Cancer Research (AACR) in Washington, DC (April 6^th to 10^th).  IGDRASOL is a privately-held company for which STI was granted an irrevocable option right to acquire.  The two companies' combined pipeline features an oncology franchise of potential products with Phase 2 data for multiple solid tumor indications as well as two synergistic drug discovery and development platforms, namely the G-MAB® human antibody library and MABiT™, a proprietary technology to generate antibody formulated drug conjugates (AfDC).

Cynviloq™ (or IG-001) is a next-generation, branded, micellar diblock copolymeric paclitaxel formulation currently approved and marketed in several countries as Genexol-PM®. Cynviloq™ has completed Phase 1 or 2 trials in MBC, NSCLC, pancreatic cancer, ovarian cancer and bladder cancer in the U.S. and/or non-U.S. IGDRASOL is preparing for an "End of Phase 2" meeting with the U.S. Food & Drug Administration (FDA) targeted for the first half of 2013 regarding Cynviloq™.  As an injectable nanoparticle formulation of paclitaxel, Cynviloq™ is potentially eligible for approval via FDA's 505(b)(2) bioequivalence regulatory pathway versus albumin-bound paclitaxel (nab-paclitaxel; Abraxane®) in its currently approved MBC and NSCLC indications. Abraxane® sales exceeded $400 million in MBC in fiscal 2012.
