Commenting on NantKwest’s clinical progress, Patrick Soon-Shiong, MD, Chairman and CEO remarked, "The complex biology of cancer requires a similarly complex war against cancer that will require combination immunotherapy. We believe NantKwest’s novel, off-the-shelf natural killer cell therapy represents a critical backbone that enables the up regulation of both the innate immune system and the adaptive immune system to begin to successfully fight the war against cancer."

Dr. Soon-Shiong continued, "I am also pleased to announce that with the proceeds from our IPO, the company has rapidly expanded its manufacturing capabilities and with the infrastructure now in place, we are now ready to translate these programs into human clinical studies over the next 6-12 months and look forward to sharing more details on these individual clinical trials over the next few months."
