Clinical Trial Summary

This randomized two-arm intervention trial administers 8 weekly cognitive behavioral therapy (CBT) sessions and 4 bi-weekly active whole-body hyperthermia (active WBH) sessions or 4 bi-weekly sham WBH sessions to adults aged 18 years or older with major depressive disorder (MDD).

Description:

Major Depressive Disorder afflicts more than 300 million people worldwide and is the leading cause of life years lost to disability. Current treatments have important limitations in efficacy and, in the case of medication, substantial side-effects. There is thus a compelling need for additional effective, well-tolerated treatments. One such potential treatment is whole-body hyperthermia (WBH). The investigators hypothesize that active WBH may be particularly effective in combination with cognitive behavioral therapy (CBT), an established treatment for depression. This randomized two-arm trial will pilot and optimize procedures for randomizing participants to receive CBT (8 weekly sessions) and 4 bi-weekly whole-body hyperthermia (active WBH) or 4 bi-weekly sham WBH sessions. This work holds important promise to improve treatment of depression and advance understanding of the role of integrated mind-body therapies for mood disorders.

Eligibility

Exclusion Criteria:

• >30% reduction in BDI-II score between Screen #1 and Screen #2 (conducted ~1 week after Screen #1)
• Suicide attempt in the past 12 months defined using the SAMHSA suicidality question during the clinician-administered interview or active suicidal ideation as indexed by a score of 3 on the BDI-II suicidality item during the clinician-administered interview
• Any of the following medical conditions: cardiovascular disease (other than controlled hypertension), seizure disorder, history of cerebrovascular accident (CVA) or other serious neurological condition (e.g. Parkinson's disease, multiple sclerosis, or dementia), current neoplasia, any active enclosed infection (e.g. dental abscess, joint infection), hemophilia or other cause for excessive bleeding (e.g. platelet disorder), or other medical condition that in the opinion of investigators may increase the risk of WBH
• Comorbid psychiatric conditions or history of comorbid psychiatric conditions that might better explain depressive symptoms, including schizophrenia, schizoaffective disorder, Bipolar Disorder I, Obsessive Compulsive Disorder, Anorexia Nervosa, Bulimia Nervosa, Alcohol Dependence, or Drug Dependence
• Known hypersensitivity to hyperthermia and/or infrared exposure
• Inability to fit into the sauna device
• Breast implants
• Pregnancy, active lactation or intention to become pregnant during the study period
• Use of any medication that might impact thermoregulatory capacity, including:

Diuretics, barbiturates, beta-blockers, antipsychotic agents, anti-cholinergic agents or chronic use of antihistamines, aspirin (other than low-dose ASA for prophylactic purposes), medication prescribed for the treatment of depression (antidepressant medication [ADM]) including but not limited to: selective serotonin reuptake inhibitors [SSRIs], Serotonin and norepinephrine reuptake inhibitors [SNRIs], Monoamine oxidase inhibitors [MAOIs], Tricyclics [TCAs], and atypical antipsychotic and antidepressant medications (participants must have been free of these medications for at least 4 weeks), antibiotics (past 14 days), pain medication (opioids) due to procedure, e.g., dental procedure (past 14 days), Emergency contraception pill (past 14 days) any other medication that in the judgment of the PI would increase risk of study participation or introduce excessive variance into physiological or behavioral responses to WBH recent use (multiple consecutive doses) of: non-steroidal anti-inflammatory drugs (NSAIDs), systemic corticosteroids, cytokine antagonists

• Regular use of any nicotine products, including cigarettes, vapes, chewing tobacco, or other forms of nicotine (if use is not regular, must be willing to refrain for 24 hours before and 24 hours after WBH session)
• Unwilling to refrain from using marijuana products and alcohol for the 24 hours before and 24 hours after WBH session
• Unwilling to refrain from heavy exercise on the day of WBH sessions
• Unwilling to refrain from engaging with sauna, hot yoga, cold plunges, cryotherapy, and hot tub/jacuzzi outside of study (prospective participant must not have engaged with any of these activities for 30 days prior to their baseline study visit).
• Has begun new psychotherapy treatment in the prior 6 weeks

Intervention

Behavioral:
• Cognitive Behavioral Therapy (CBT)
Cognitive Behavioral Therapy (CBT) is a behavioral (psychotherapeutic) intervention for major depressive disorder (MDD). A highly trained masters' or PhD-level clinician will administer 8 weekly CBT sessions (~50 minutes each), following the standard cognitive behavioral therapy for depression protocol.

Device:
• Active Whole-Body Hyperthermia (Active WBH)
Active whole-body hyperthermia (active WBH) will be administered by trained research assistants. Preparation for the active WBH session, the active WBH session, and cool down will last 3.5 hours, with heating lasting approximately 90-100 minutes (and no longer than 140 minutes). The treatment will take place in an infrared sauna dome, and the active heating phase will last until the participants has achieved a core (rectal) temperature of 38.5 C.
• Sham Whole-Body Hyperthermia (Sham WBH)
Sham whole-body hyperthermia (sham WBH) will be administered by trained research assistants. Preparation for the sham WBH session, the sham WBH session, and cool down will last 3.5 hours, with heating lasting approximately 90-100 minutes (and no longer than 140 minutes). The treatment will take place in an infrared sauna dome, and the sham WBH session will minimally impact core body temperature.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Sudden gains in antidepressant responses	Sudden gain in BDI-II scores, defined as >25% reduction in depression symptoms in between between two adjacent sauna sessions, account for more than 50% of total depression symptom improvement	2-3 weeks
Primary	Net Promoter Score	Study acceptability will be indexed by participant-reported net-promoter scores. This is a response to a single question: "How likely would you be to recommend [participation in a study or treatment like this] to a friend or family member with depression?" Net promoter scores range from 0 (would not recommend) to 10 (would definitely recommend).	12 weeks
Secondary	Change in Beck Depression Inventory-II (BDI-II)	Change in BDI-II from baseline assessment to final assessment. Scores range from 0 to 63 and items are summed to create a total score; higher scores indicate greater depression symptoms.	Baseline and 12 weeks
Secondary	Change in Patient-Reported Outcomes Measurement Information Systems (PROMIS) 8a Depression	Change in PROMIS8a Depression from baseline to final assessment. T scores are computed; higher scores indicate greater depression symptoms.	Baseline and 12 weeks
Secondary	Change in Hamilton Depression Rating Scale 6-item (HAMD-6) Self-Report	Change in HAMD-6 from baseline to final assessment. Scores range from 0 to 22, and items are summed to create a total score; higher scores indicate greater depression symptoms.	Baseline and 12 weeks
Secondary	Change in Patient-Reported Outcomes Measurement Information Systems (PROMIS) 4a Anxiety	Change in PROMIS4a Anxiety from baseline to final assessment. T scores are computed; higher scores indicate greater depression symptoms.	Baseline and 12 weeks
