Clinical Trial Summary

This is an extension of EM 1000-1 wherein subjects who participated in the original study have been given the opportunity to participate in a 4-month extension of TEMT. Seven of the eight subjects in the original EM 1000-1 agreed to participate in this study extension. The time between completion of the initial study's 2-month treatment period and the beginning of this extension study's 4-month treatment period will range from 4 months to 13 months (due to staggered start of treatment in the initial study). This extension study's primary objective is to determine the effects of a follow-up treatment period of 4-months on performance of Alzheimer's Disease (AD) subjects in the same comprehensive array of cognitive tasks they performed in the initial 2-month treatment study. Baseline cognitive performance will be compared to performance at both 2-months into treatment and at the end of the 4-month treatment period. Secondary objectives include analysis of blood and CSF for AD markers and evaluation of safety throughout the treatment period.

Description:

The present study is an Open-Label within-patient (single arm) extension study of our Open-Label initial study (EM1000-1) whereby seven of the eight Alzheimer's subjects participating in the initial study agreed to participate. The present study is intended to continue evaluation of the safety and efficacy of Transcranial Electromagnetic Treatment (TEMT) in patients with mild-to-moderate Alzheimer's Disease who had previously participated in the initial Open-Label study. The study duration for each subject is approximately 4 1/2 months, which involves a total of four clinical visits: pre-baseline, baseline, 2-months into treatment, and at treatment completion (4-month into treatment).

This extension study will utilize the same MemorEM 1000 head devices (designated as NSR) as in the initial 2-month treatment study, but will involve daily treatment for a longer four month period. Only one 1-hour treatment will be administered per day rather than the two 1-hour treatments per day administered in the initial 2-month study because: 1) the extension study involves a longer period of treatment, and 2) preliminary results from the initial 2-month study show a strong carry-over effect of treatment on cognitive performance after the 2-month treatment period had been completed (14 days after end of treatment).

Cognitive safety/efficacy will be evaluated using the same battery of cognitive tasks as in the initial study. These include ADAS-cog (primary outcome), and secondary cognitive outcomes of Rey AVLT, MMSE, ADCS-ADL, Digit span, Trails A & B, and clock draw tasks. Additional secondary outcomes involve analysis of blood and CSF (collected at baseline, 2-months and/or 4-months into treatment) for various beta-amyloid and tau protein species. As another secondary outcome, safety of TEMT will be monitored by regular Adverse Events Assessment, physiologic monitoring, and patient daily diaries maintained by the caregiver.

Expected Results: The investigators expect that 4-months of once-daily TEMT will not present any significant sides effects or safety issues to the seven subjects who were initially provided the same treatment twice-daily for 2-months. The investigators further expect that cognitive measures will be stable and/or improve by the end of the the treatment period. In addition, changes in blood/CSF levels of various beta-amyloid and tau species are anticipated that reflect the mechanisms of TEMT action.

• History of Epileptic Seizures or Epilepsy

• Patients with major depression (not controlled with medication), bipolar disorder or psychotic disorders or any other neurological or psychiatric condition (whether now or in the past). The investigator will obtain this information from available patient medical records, history provided by the patient and caregiver, interview, and neurological exam.

• Patients with vitamin B12 deficiency, abnormal thyroid function, or personal history of either any clinically defined medical disorder or any clinically defined neurological/psychiatric disorder (other than AD), including (but not limited to):, stroke, brain lesions, , cerebrovascular condition, other neurodegenerative disease, significant head trauma (loss of consciousness greater than half an hour, or related anterograde amnesia), multiple sclerosis; or personal history of previous neurosurgery or brain radiation

• Patients with any signs or symptoms of increased intracranial pressure, as determined in a neurological exam.

• Patients with demonstrated brain micro-hemorrhages (more than 5) at screening

• Patients with a score of 4 or higher on the Hachinski Test

• Patients with CDR Global Score of 0, 0.5, or 3

• Patients with hypertension that is unresponsive to anti-hypertensive medications

• Patients with a history of migraine headaches occurring more than once a month

• Patients with a history of cancer within last 3 years (basal cell and squamous cell carcinomas will be considered on a case by case basis by investigator)

• Patients chronically taking anticoagulants or anti-platelets (at discretion of PI)

• Cardiac pacemakers

• Implanted medication pumps

• Intracardiac lines

• Significant heart disease

Intervention

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 emitters in the head cap worn by the subject. The device provides global treatment to forebrain. For each of the 120 days of in-home treatment, a single 1-hour treatment will be administered by the subject's caregiver, who will position the device on the patient's head and monitor treatment.
