Treatment is delivered via infusion where our active ingredient is administered directly into the bloodstream through an intravenous (IV) line. Unlike oral medications, infusion therapy ensures fast absorption, precise dosing, and continuous delivery of drugs, making it ideal for biological therapies like NK cell-derived extracellular vesicles (NKEVs). This method is widely available at hospitals, outpatient clinics, and community infusion centers, providing a convenient and effective treatment option for patients. NKEV infusion is naturally biocompatibility with reduced risk of immune rejection, and a promising next-generation immunotherapy for difficult-to-treat cancers.
