There is currently no effective therapeutic to stabilize or reverse the cognitive impairment of Alzheimer's Disease (AD) and related dementias. Clinical trials with drugs have been unsuccessful because the wrong therapeutic target/species were selected, because drugs have great difficulty traversing the blood-brain barrier and getting into neurons, and/or because drugs largely have only a single mechanism of action. Since ever-increasing experimental evidence indicates that the toxic forms of both beta-amyloid and tau are the soluble "oligomeric" species of these two proteins, therapeutics to disaggregate these oligomers within neurons represent perhaps the best chance for attaining cognitive benefit in AD patients.
Pre-clinical studies performed by the Sponsor and his collaborators have demonstrated that AD transgenic mice treated daily with electromagnetic waves in the radiofrequency (RF) range are protected from cognitive impairment or show a reversal of pre-existing cognitive impairment. These cognitive benefits appear to be due primarily to two complimentary mechanisms: 1) disaggregation of toxic protein oligomers within neurons, and 2) mitochondrial enhancement to increase energy metabolism. Moreover, no deleterious effects of treatment over many months have been observed in these pre-clinical studies.
In order to provide similar treatment to mild/moderate Alzheimer's patients clinically, NeuroEM Therapeutics has developed a unique head device that provides electromagnetic (RF) treatment to the entire human forebrain at levels similar to those that provided cognitive benefits in pre-clinical studies. Using the MemorEM 1000 head device in the present Phase I trial, AD patients receive twice daily 1-hour treatments in-home, as administered by their caregiver. The device allows for the patient to have complete mobility for moving throughout their home.
A comprehensive array of markers will be analyzed both during and following the 2-month treatment period, with baseline (pre-treatment) values serving as controls. Cognitive safety and efficacy will be evaluated using a variety of cognitive assessments including ADAS-cog (Primary), and secondary cognitive measures including ADCS-ADL, Rey AVLT, Trails A & B, Digit span, and clock draw tasks. Treatment effects on brain energy metabolism will be determine by FDG-PET scans, while treatment effects on brain functional connectivity will be determined through both resting state MRI and Diffusion Tensor Imaging. Also being assessed are the effects of treatment on various beta-amyloid and tau protein species (e.g., monomers, oligomers) in both blood and CSF. Safety of the treatment will be monitored by regular Adverse Events Assessment, physiologic monitoring, and patient daily diaries maintained by the caregiver.
Expected Results: The investigators expect that 2-months of daily electromagnetic (RF) treatment will not present any significant side effects or safety issues. The investigators further expect that cognitive measures will be stable and/or improve by the end of treatment. In addition, the investigators anticipate that brain functional connectivity may be improved and that enhanced brain metabolism (FDG-PET) will occur. Changes in blood/CSF levels of various beta-amyloid and tau species are also anticipated.

Experimental: TEMT Treatment
Patients in this arm will receive Transcranial Electromagnetic Treatment (TEMT) twice daily for a two-month treatment period utilizing the MemorEM 1000 head device.
Device: MemorEM 1000
The MemorEM 1000 device is self-contained and has been designed for in-home daily electromagnetic treatment in the radiofrequency range, allowing for complete mobility and comfort in performing daily activities during treatment. The device has a custom control panel that is powered by a rechargeable battery. This control panel/battery box is worn on the upper arm and wired to specialized antennas in the head cap worn by the subject. The device provides global RF treatment to the entire forebrain, including deep brain areas. For each of the 60 days of in-home treatment, two one-hour treatment will be given (early morning and late afternoon). Each treatment will be administered by the patient's caregiver, who will position the device on the patient's head and monitor treatment.
