Whole Body Hyperthermia and Major Depression (MDD)
August 6, 2015 updated by: Charles (Chuck) Raison, University of Arizona
Major depressive disorder (MDD) is predicted to be the second leading cause of disability worldwide by the year 2020.
The economic burden of depression in the United States is significant: $83.1 billion in 2000 and increasing.
Much of this burden comes from the high rate of sub-optimal treatment outcomes associated with the disorder.
Indeed, only 50% of MDD patients recover in less than 12 weeks with adequate treatment, and up to 20% of patients will fail to adequately respond to all currently available interventions.
Moreover, current treatments come at the cost of significant central nervous system (CNS) side effects, further highlighting the need for more effective treatments with fewer side effects.
This study will compare temperature ranges from the investigators preliminary studies involving thermoafferent pathways resulting in antidepressant actions with lower temperature ranges not expected to activate these pathways as a control condition, with the goal to evaluate whether previous observations were related to the temperature range in question or can be achieved with other levels.

Detailed Description
We will conduct a placebo controlled clinical trial to determine if Whole Body Hyperthermia has antidepressant effects in medically healthy patients with moderate to severe MDD.
We plan to recruit a sample of 30 medically healthy individuals with MDD who will be randomized to examine whether WBH will demonstrate an antidepressant effect when compared to a control-WBH condition that will be comprised of very mild heating in the WBH machine (Heckel HT3000).
To determine acute and sustained effects of WBH on depression severity, the study will include basic clinical and psychiatric assessments 5 days before and after WBH and follow-up assessments at 2, 4, and 6 weeks following WBH.
Additionally, assessments will be conducted during the optional open treatment, 1 week following the open treatment, and at the 3 month follow up.
To assess whether WBH affects how individuals relate to other people in their environment, as well as how they spend their time in general and to assess social processes, the study will employ the Electronically Activated Recorder (EAR).
Participants will wear the EAR device during the day, while going about their lives over the weekend.
This weekend monitoring also includes an actigraphy assessment during which participants will wear an actigraphy device during their waking and sleeping hours.
In addition, blood will be obtained at multiple time points to assess plasma concentrations of biological predictors or response and mechanism of action for WBH.
This study challenges the existing paradigm by determining if peripheral afferent sensory pathways can be accessed to treat MDD and thus avoid problems of exposing all of the brain to non-selective drugs.

- Reasonable likelihood for non-compliance with the protocol for any other reason, in the opinion of the Investigator, prohibits enrollment of subject into the study.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: High intensity whole-body infrared heating
Subjects will be induced to levels of heat that increases core body temperature to approximately 37.5-38.5 °C using the Whole Body Hyperthermia system.
|
The Whole Body Hyperthermia system uses water-filtered infrared-A (wIRA) heat radiation.
The rise in the body's core temperature is correspondingly rapid and well-tolerated.
There are two phases of the thermal challenge, 1) Irradiation phase during which the patient lies recumbent with his/her head positioned outside the tent.
The wIRA irradiators are arranged above the exposed upper part of the body; and 2) Heat retention phase during which the patient lies in the chamber with the walls of the tent positioned to retain heat.

Sham Comparator: Low intensity whole-body infrared heating
Subjects will be induced to levels of heat that causes only a minor increase in body temperature using Whole Body Hyperthermia system.

Core body temperature monitoring
Time Frame: 3 days (over the weekend) at baseline, week 1 and week 4.

Body temperature will be measured with a Vitalsense unit (Minimitter Respironics, Bend OR).
The Vitalsense system includes easy to swallow telemetric capsules about the size of a multivitamin (dimensions 23 cm x 8.7 mm) made of medical grade plastic (biocompatible polycarbonate).
After ingestion, pills normally pass between 1 to 5 days (mean 2 ± 1.5 days) and then are discarded.
A second pill will be ingested if the pill passes during the study visit.
Pill temperature sensors transmit data to a small, battery operated, lightweight, user-worn device that may be worn on a belt or placed in a pocket (Dimensions 120 x 90 x 25 mm; weight 200 grams).
The devise can collect up to 10 channels for 240 h without battery replacement or download.
