Median OS Not Yet Reached and Lymphopenia Reversed in Recurrent GBM Patients Receiving ANKTIVA® Plus CAR-NK, Chemo-Free Therapy

“These Phase 2 data reflect outcomes in a second- and third-line glioblastoma population where immune collapse after standard therapy is common and options are limited. With 19 of 23 enrolled patients alive and median overall survival not yet reached, the survival profile warrants continued follow up,” said Patrick Soon Shiong, M.D., Founder, Executive Chairman and Global Chief Scientific and Medical Officer of ImmunityBio. “It has been extensively reported that patients with glioblastoma and lymphopenia have a significant decreased survival. Current standards of care, including radiation and chemotherapy (temozolomide), are potent drivers of lymphocyte depletion. The patients that entered this study all suffered profound lymphopenia, reflected by a baseline mean ALC of approximately 900, consistent with prior radiation and chemotherapy exposure. On treatment, we observed recovery and maintenance of lymphocyte counts without chemotherapy. Notably, within this broader clinical and compassionate use experience, we have also observed a near complete response with survival extending beyond twelve months from the time of documented disease progression, an outcome rarely seen in recurrent glioblastoma.”
