Sorrento is a clinical stage oncology company developing new treatments for cancer and associated pain. Sorrento announced that it recently entered into a definitive agreement with Dr. Patrick Soon-Shiong’s NantPharma to acquire the rights for Cynviloq™, which recently completed the TRIBECA™ study successfully, from Sorrento. The company is also developing resiniferatoxin (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.

In December 2014, Sorrento and NantWorks formed a global joint venture, now called Nantibody, to focus on immunotherapies for cancer. Also in December 2014, Sorrento and Conkwest, Inc., an immuno-oncology company developing proprietary Neukoplast®, a Natural Killer (NK) cell-line based therapy, entered into an agreement to jointly develop CAR.TNK™ (Chimeric Antigen Receptor Tumor-attacking Neukoplast) immunotherapies for the treatment of cancer and infectious diseases. In March 2015, Sorrento entered into a global collaboration with NantCell, a NantWorks company, to discover and develop immunotherapies against tumor neo-epitopes.
