Adaptive tDCS for Treatment-Resistant MDD

Stopped early · Phase 1

Conditions studied: Depressive Disorder, Treatment-Resistant

In brief

This pilot study aims to investigate the potential role of transcranial direct current stimulation (tDCS) in the treatment of treatment-resistant major depressive disorder (MDD). tDCS is a noninvasive brain stimulation technique which has been utilized for the treatment of major depression in several studies, both as a primary and adjunctive treatment. The treatment will be administered under the supervision of a physician with experience in administering the treatment and monitoring for complications. This will be a prospective "adaptive tDCS stimulation" open label research study. Participants will receive 20 minute sessions of up to 4 milliamps (mA) transcutaneous electrical stimulation sessions over 4 to 6 weeks. Building on the theory that greater current "dose" may be a significant factor in determining efficacy, this study aims to determine whether higher tDCS current doses lead to greater improvements in depressive symptoms in this population of patients with treatment-resistant major depressive disorder.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Adults age 18 to 65
• History of major depressive disorder with current depressive symptoms, as defined by DSM-IV criteria
• Baseline score of Hamilton Depression Rating Scale 17-item (HDRS-17) score of 17 or higher
• Failure of at least 3 prior lifetime antidepressant trials
• Good command of the English language

You may not qualify if…

• Lifetime history of the following, defined by DSM-IV criteria per study physician:
• Moderate or severe substance use disorder in the past 6 months with the exception of nicotine use disorder
• Dementia or major neurocognitive disorder
• Schizophrenia spectrum disorders
• Autism spectrum disorder
• Depression which has failed to respond to ECT, with treatment failure as determined by evaluating physician
• Failure of greater than 6 antidepressant trials in the current depressive episode
• Current evidence of the following, defined by present symptomology as per study physician:
• Active psychotic symptoms
• Bipolar disorder with a current manic, hypomanic, or mixed episode as defined by DSM-IV criteria
• Depression secondary to a general medical illness
• Dysphoria better explained by a personality disorder
• Dysphoria associated with a primary anxiety disorder or PTSD
• Active suicidal intention (inability to contract for safety)
• Any change in psychotropic medication within 30 days of the initiation of tDCS
• History of neurological disorders (e.g., epilepsy) and/or off any treatment medication for a neurological disorder for minimum 3 years (36 months)
• Any open wounds (e.g., blisters, burns including sun burns, cuts or irritation) under or near the scalp regions where electrodes are placed
• Metal implants (e.g., Deep Brain Stimulator, Vagus Nerve Stimulator)
• Any skin disorders (e.g., eczema, severe rashes, sensitive skin, any communicable skin disorder or treatment for a communicable skin disorder in the past 12 months) or other skin defects which compromise the integrity of the skin at or near stimulation locations (where electrodes are placed)
• Any history of head injury resulting in unconsciousness for more than 5 minutes (e.g., head trauma, brain surgery)
• Metallic face or scalp tattoos
• Any chronic headaches or migraines (occurring for consecutive days and are longer than an hour)
• If a participant has a change in the rate or severity of head pressure, headache, or migraine in the past two weeks, they will also be excluded as per study clinician as we are not aiming to assess the treatment of headache with tDCS
• Any personal history of seizures.
• Currently pregnant or lactating, as determined in part from urine pregnancy test at Screening/Baseline appointment and medical history.
