Method for noninvasive whole-body stimulation with spinning oscillating magnetic fields and its safety in mice

We recently reported shrinkage of untreatable recurrent glioblastoma (GBM) in an end-stage patient using noninvasive brain stimulation with a spinning oscillating magnetic field (sOMF)-generating device called the Oncomagnetic device. Our in vitro experiments demonstrated selective cancer cell death while sparing normal cells by sOMF-induced increase in intracellular reactive oxygen species (ROS) levels due to magnetic perturbation of mitochondrial electron transport. Here, we describe the results of an in vivo study assessing the toxicity of chronic sOMF stimulation in mice using a newly constructed apparatus comprised of the sOMF-generating active components of the Oncomagnetic device. We chronically stimulated 10 normal 60-day old female C57BL/6 mice in their housing cages for 2 h 3 times a day, as in the patient treatment protocol, over 4 months. We also studied the effects of 2-h acute sOMF stimulation. Our observations and those of blinded independent veterinary staff observers, indicated no significant adverse effects of chronic or acute sOMF stimulation on the health, behavior, electrocardiographic and electroencephalographic activities, hematologic profile, and brain and other tissue and organ morphology of treated mice compared to age-matched untreated control mice. These findings suggest that short- and long-term therapies with the Oncomagnetic device are safe and well tolerated.
