Aethlon Medical, Inc. announced positive results from an in vitro binding study of its Hemopurifier in removing extracellular vesicles (EVs) from plasma. The translational study provides pre-clinical evidence to support Aethlon's planned phase 1 safety, feasibility and dose-finding clinical trials of the Hemopurifier in patients with solid tumors who have stable or progressive disease during anti-PD-1 monotherapy treatment, such as Keytruda or Opdivo.
