Aethlon Medical's Hemopurifier® shows Changes in Extracellular Vesicles, Extracellular MicroRNAs, and T Cell Numbers in Australian Oncology Clinical Trial

Core Insights - Aethlon Medical, Inc. is conducting an ongoing oncology clinical trial in Australia to evaluate the safety, feasibility, and dose-finding of its Hemopurifier device in cancer patients unresponsive to anti-PD-1 therapy [1][2] Summary by Categories Clinical Trial Observations - Preliminary results from the first patient cohort indicate encouraging changes in extracellular vesicles (EVs), microRNAs, and lymphocyte counts after a single Hemopurifier treatment [2][3] - In the initial three patients, two showed decreases in large EVs, which are implicated in cancer metastasis and immune evasion [7] - All three participants exhibited decreases in large EVs carrying PD-L1, which is associated with resistance to anti-PD-1 therapies [7] - Seven out of ten microRNAs examined showed decreases in two of the three participants following treatment, indicating potential effects on cancer growth and metastasis [7] - Improvements in laboratory ratios related to immunotherapy responses were observed in at least two participants after treatment [7] Device Information - The Aethlon Hemopurifier® is designed to remove enveloped viruses and tumor-derived EVs from circulation, potentially aiding in cancer treatment [9] - The device operates extracorporeally and utilizes a combination of plasma separation, size exclusion, and affinity binding [9] - It holds a U.S. Food and Drug Breakthrough Device Designation for treating advanced or metastatic cancer and life-threatening viruses [10] Limitations and Future Directions - The small sample size limits the ability to draw definitive conclusions about the efficacy and dose response of the Hemopurifier [3][8] - Further data from subsequent cohorts will be necessary to determine the reproducibility of the observed changes and the potential for dose-dependent effects [3] - The current observations are part of an early feasibility study and should not be interpreted as evidence of clinical benefit or safety beyond the study parameters [8]
