About Conkwest

Conkwest is an innovative immuno-oncology company that is developing and commercializing a portfolio of highly potent and selective cellular therapies for the treatment of cancers and serious viral infections. Conkwest's products are based on its proprietary cancer-killing cell line, Neukoplast – the only known cell line that can be commercialized as a direct, scalable, off-the-shelf, cancer-killing product. Neukoplast recognizes, binds and directly kills cells expressing stress ligands such as LFA-3, Heparin Sulfate, ICAM-1 and other stress induced proteins commonly found on cancers and virally infected cells. It has demonstrated broad anti-cancer activity both in vitro and in human clinical trials while sparing patients from the serious adverse reactions often seen with CAR-T based therapies. Cancer patients have been treated in phase I clinical trials at RUSH University, University Frankfurt am Main/Germany, Princess Margaret Hospital and University of Pittsburgh Cancer Institute. Preparations for the first U.S. phase II trial in Merkel Cell Carcinoma are currently underway. Conkwest's universal antibody-targeted CD16-Neukoplast, a re-engineered product which expresses both the high-affinity version of FcgammaR3 (CD16) and ER-IL2 to efficiently bind and amplify the potency of broad spectrum therapeutic monoclonal antibodies such as Rituxan®, Herceptin® and Erbitux®, is presently in the preclinical stage of development. Conkwest also commercializes Neukopanel®, an Neukoplast based bioassay panel for the screening and qualification of therapeutic monoclonal antibody products, with revenue bearing licenses to many well-known large pharma and biotechnology companies.

About Sorrento Therapeutics, Inc.

Sorrento is an oncology company developing new treatments for cancer and associated pain. Sorrento's most advanced asset Cynviloq™, the next-generation nanoparticle paclitaxel, commenced its registrational trial in March 2014 and is being developed under the abbreviated 505(b)(2) regulatory pathway. Sorrento is also developing RTX, a non-opiate TRPV1 agonist currently in a Phase 1/2 study at the NIH to treat terminal cancer patients suffering from intractable pain. The company has made significant advances in developing human monoclonal antibodies, complemented by a comprehensive and fully integrated antibody drug conjugates (ADC) platform that includes proprietary conjugation chemistries, linkers and toxic payloads. Sorrento's strategy is to enable a multi-pronged approach to combating cancer with small molecules, mono- and bi-specific therapeutic antibodies, ADCs and CAR.taNK™ cells.

The company recently signed a definitive agreement with NantWorks to form a global joint venture – "The Immunotherapy Antibody JV" company- to focus on next generation cancer and autoimmune diseases immunotherapies. Sorrento also entered into a definitive agreement with Conkwest, Inc., a privately-held immuno-oncology company developing proprietary Neukoplast®, a Natural Killer (NK) cell-line based therapy, to jointly develop next generation CAR.taNK immunotherapies for the treatment of cancer. The CAR.taNK technology platform combines Conkwest's proprietary Neukoplast cell line with Sorrento's proprietary G-MAB® fully human antibody technology and CAR designs to further enhance the potency and targeting of Neukoplast. Under the terms of the agreement, Sorrento and Conkwest will establish an exclusive global strategic collaboration focused on accelerating the development of CAR.taNK cell lines for the treatment of hematological malignancies as well as solid tumors. Both companies will jointly own and share development costs and revenues from any developed CAR.taNK cell line products.
