Aethlon Medical Treats Second Patient In Australian Hemopurifier Trial For Solid Tumors Unresponsive To Anti-PD-1 Therapy At Royal North Shore Hospital/University Of Sydney

Second Patient in first cohort enrolled and treated at the Royal North Shore Hospital/University of Sydney

Aethlon Advances Hemopurifier® Study in Solid Tumors Not Responding to Anti-PD-1 Antibodies

SAN DIEGO, June 18, 2025 /PRNewswire/ -- Aethlon Medical, Inc. (NASDAQ:AEMD), a medical therapeutic company focused on developing products to treat cancer and life-threatening infectious diseases, today announced a significant milestone: the treatment of the second patient with the Hemopurifier in its Australian safety, feasibility and dose-finding clinical trial of the Hemopurifier. This trial is designed for patients with solid tumors who have stable or progressive disease during anti-PD-1 monotherapy treatment, such as Keytruda® (pembrolizumab) or Opdivo® (nivolumab) (AEMD-2022-06 Hemopurifier Study). The patient was treated with the Hemopurifier June 11, 2025 by Genesis Care and Royal North Shore Hospital/University of Sydney. Professor Stephen Clarke, Medical Oncologist, is the Principal Investigator for the study and the Hemopurifier session was supervised by Dr. Emma O'Lone.

Ongoing progress has been made in our Australian Oncology trial of the Hemopurifier in participants with solid tumors not responding to anti-PD-1 agents. We have now completed Hemopurifier treatments in 2 participants in the first cohort. Our first participant completed the Hemopurifier treatment at Royal Adelaide Hospital on January 29, 2025. Participant # 2 was treated with the Hemopurifier at Royal North Shore/University of Sydney on June 2, 2025. Both participants completed the 4-hour Hemopurifier treatment without device deficiencies or immediate complications. As of June 10, 2025, both patients have completed the pre-specified 7-day safety follow-up period that will be presented to an independent Data Safety Monitoring Board (DSMB) following the treatment of a third patient in the cohort.

The DSMB will review safety data on this first cohort and provide a recommendation to Aethlon Medical Senior Leadership about advancing to the second treatment cohort where 3 participants will receive 2 Hemopurifier treatments during a one-week period. We would expect data on extracellular removal by the Hemopurifier and effects on anti-tumor T cell activity on participants in the first cohort in approximately three months following enrollment of the third patient.
