Nano-Pulse Stimulation Treatment Inhibits Pan02 Murine Pancreatic Tumor Growth and Induces a Long-Term Adaptive Immune Response with Abscopal Effects When Combined with Immune-Enhancing Agents.

Pancreatic cancer is associated with a poor prognosis and immunotherapy alone has not demonstrated sufficient efficacy in the treatment of nonresectable tumors. Nano-Pulse Stimulation™ therapy (NPS™) applies nanosecond electric pulses that lead to regulated cell death, exposing tumor antigen to the immune system. To establish a primary Pan02 tumor, mice were intradermally injected with Pan02 cells into the right flank.

Nano-pulse stimulation™ therapy (NPS™) is superior to cryoablation in clearing murine melanoma tumors.

Background: Nano-Pulse Stimulation™ Therapy (NPS™) is a new, bioelectric modality that applies ultrashort pulses of electric energy to trigger regulated cell death in treated tissues. Instead of initiating necrosis by heating or freezing, NPS therapy permeabilizes intracellular organelles to activate the cell's own self-destruct pathway of programmed or regulated cell death. Unlike cryotherapies that can both damage structural tissues and diffuse into the periphery beyond the margins of the lesion, NPS only affects cells within the treated zone leaving surrounding tissue and acellular components unaffected.
