TMS vs ECT for Depression

Lexington, Kentucky
Electroconvulsive therapy (ECT) is one of the most efficacious treatments available for treatment-resistant depression (TRD). Although a maintenance ECT protocol exists, multiple barriers limit its use for long-term use. These barriers include procedure tolerability, cognitive side effects, financial burden, and unreliable social support to accompany patients for these treatments. On the other hand, a different modality of noninvasive neuromodulation called transcranial magnetic stimulation (TMS) can be performed in the outpatient setting and does not need anesthesia. The likelihood of cognitive adverse effects with TMS is much lower than with ECT. Our clinical question encompasses piloting a maintenance TMS regimen to maintain remission in treatment-resistant major depressive disorder. This will be a patient-preference clinical trial, with patients offered the choice to initiate maintenance TMS versus maintenance ECT after their index ECT sessions for treatment-resistant depression. There will be no randomization or placebo involved in this study.

The goal of this clinical trial is to learn if Transcranial Magnetic Stimulation (TMS) to part of the brain called the ventromedial prefrontal cortex (VMPFC) can treat a symptom called rumination in adults with major depression that has not responded to at least one medication trial. The main question it aims to answer are: Does TMS to the VMPFC change brain activity on functional magnetic resonance imaging (fMRI) during a negative self-referential processing task in adults with depression? Does TMS to the VMPFC affect rumination in adults with depression? Researchers will compare brain scans and rumination scores before, during, and immediately after TMS. Participants will: Undergo three functional MRI scans Undergo a course of 20 TMS treatments Respond to clinical questionnaires and complete a computer behavioral task

This trial is testing whether inhaling nitrous oxide gas, along with regular treatment, can quickly reduce suicidal thoughts in patients who are in immediate danger. The gas works by affecting brain chemicals to improve mood rapidly. Researchers hope it will be a safe and effective way to help these patients with minimal side effects. Nitrous oxide has been used for over a century in various medical fields for pain relief and sedation, and recent studies suggest it may be effective for depression that hasn't improved with other treatments.

The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.

Major Depressive Disorder (MDD) is a very common illness that is usually treated with antidepressant medication. Depression can be caused by many things such as childhood experiences, genetics, and changes in the way the body and brain function. For those with depression where medication and psychotherapy have limited benefit, repetitive transcranial magnetic stimulation (rTMS) is an effective treatment. rTMS is a treatment that involves stimulating certain areas of the brain with magnetic field pulses. Over time, the magnetic field pulses can gradually change the activity level of the stimulated brain region. This can be helpful in treating some kinds of psychiatric and neurological disorder, including MDD. It is not fully known how rTMS changes brain activity to improve symptoms of depression. However, certain brain areas responsible for behaviours impacted by depression are underactive in those with depression. One of those brain regions called the dorsolateral prefrontal cortex (DLPFC), and the investigators will target this region using rTMS. By increasing the activity of these regions, rTMS could potentially improve depression symptoms. For participants receiving rTMS, the investigators will be using the participant's brain scan to better understand brain activity of the brain region stimulated by rTMS before and after treatment. In this study, the investigators will be collecting detailed information about participants' psychiatric history and depression symptoms, as well as brain scans and saliva samples. The saliva samples will undergo proteomic (having to do with proteins) analyses to identify biological markers ("biomarkers": biological features (e.g.: gene, protein) that can be measured to indicate factors related to rTMS response. The investigators' goal is to use this information to help us understand whether improvement to rTMS depends on brain activity or proteomic factors localized to two specific behaviours impacted by depression: reward processing and working memory (the capacity to hold information temporarily, such as holding a person's address in mind while listening to instructions about how to get there).

The purpose of this trial is to determine if intermittent theta-burst stimulation (iTBS) can reduce the symptoms of depression in treatment-resistant bipolar disorder. To do this, some of the participants in this study will receive treatment with active iTBS stimulation, while others will receive sham iTBS stimulation. Participants will come for 30 days of either active iTBS or sham iTBS, with a 6-week follow-up period. Symptoms of depression (for determining treatment efficacy) and mania (for determining treatment safety) will be assessed using the 17-item Hamilton Rating Scale for Depression (HRSD-17) and the Young Mania Rating Scale (YMRS) every five treatments during the treatment course, and at 1 week and 6 week after treatment completion.

Depression is a common condition, with serious negative effects on the health and quality of life of those affected. While there are currently various medications which attempt to treat depression, they often take a long time to begin to work and do not work at all for many people. There is therefore a need for new treatments which work quickly and effectively. One such medication is called ketamine. Studies have shown that ketamine can treat symptoms of depression quickly. This quick action sets ketamine apart from many antidepressants that take weeks to show noticeable effects. One way that it may do this is by creating a transient sense or feeling of being separated from reality, such as seeing or hearing things that are not really there. Another way to create these same feelings is with virtual reality (VR), where a person can feel as though they are entering a 3-dimensional virtual computer-generated world by wearing a special headset or goggles with a computer inside. In this study, all participants will receive standard ketamine treatments for depression. Half of the participants will also use a VR headset while receiving the ketamine treatments to see if ketamine and VR acting together provide a better treatment for symptoms of depression than ketamine alone. This is a small pilot trial. The main purpose of this trial is to learn if it is possible to run a larger clinical trial comparing "ketamine and VR" with "ketamine alone", for adults with treatment-resistant depression. The researchers will study this by seeing how many participants take part in the study within 1-2 years, and how many complete the study treatments and tests. The researchers will also compare the two study groups to see if "ketamine and VR" provide a better treatment for symptoms of depression than "ketamine alone".

Limit: 5000 characters. Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of certain medications such as risperidone. The purpose of this study is to use an established SV2A radiotracer produced at our Centre to determine the feasibility of integrating PET imaging in to psilocybin trials. The preliminary imaging data will assess whether psilocybin's antidepressant effects are related to changes in synaptic density in adults with TRD, and whether any changes in synaptic density are associated with psilocybin's actions on the 5-HT2AR.

We propose a first-of-its-kind open-label clinical trial to investigate the feasibility, tolerability, and safety of administering psilocybin in autistic adults with treatment-resistant depression (TRD). In this study, 20 participants (intellectually able and fluent-speech adults) with autism and co-occurring TRD will receive around 20 hours of manualized psychotherapy that has previously been used with psilocybin (Agin-Liebes et al., 2020). They will also receive psilocybin at 2 different time points, firstly a safety dose of 10mg, followed by a treatment dose of 25mg. This study design is in accordance with previous studies investigating the use of psilocybin with psilocybin-assisted therapy (PAT) to treat TRD (Carhart-Harris et al., 2016, 2018)

This study aims to explore how repetitive transcranial magnetic stimulation (rTMS), a treatment for depression, affects brain function. Depression disrupts the brain's complex network or regions that regulate cognition, emotion, and behavior. rTMS targets these disruptions to restore network function. To measure these effects, researchers will use dry quantitative EEG (qEEG), a new technology that records brain electrical activity quickly (15 minutes compared to 1 hour for traditional EEG) without the need for gel or lengthy electrode setups. This study will evaluate a novel qEEG activity developed by iMediSync (Republic of South Korea) in patients treated with neuromodulation for depression before, during, and up to 12 months after treatment to see if changes in brain activity to identify patterns associated with symptomatic improvement and relapse risk. Findings could help personalize depression treatments by predicting patient outcomes and optimizing care.

This study is an open-label, single-arm, proof-of-concept study, wherein treatment resistant bipolar depression (TRBD) participants will receive one 25 mg dose of oral psilocybin accompanied by preparatory, monitoring, and integration psychotherapy sessions (psilocybin-assisted psychotherapy, or PAP). Using fMRI (functional magnetic resonance imaging), the findings of this study will provide data on the neurobiological mechanism of psilocybin in TRBD. The primary objective is to understand the dynamic role of amygdala activity by evaluating the neurobiological effects of a single psychedelic dose (25 mg) of oral psilocybin in individuals with a moderate to severe major depressive episode and a primary diagnosis of Bipolar II Disorder, with 2 or more failed treatment trials (i.e., treatment resistant bipolar depression \[TRBD\]). Neurobiological effects will be determined by evaluating the association between post-treatment right amygdala activity during the facial affect task (determined by fMRI one day after the psilocybin dose) and antidepressant effects (determined by changes in the Montgomery-Åsberg Depression Rating Scale \[MADRS\] scores over time, during the one-week period post-psilocybin dose). This is a single-arm, open-label clinical trial wherein all participants will receive the same study intervention. Hypothesis: Increased right amygdala activity on fMRI with emotional stimuli one day after psilocybin treatment will be associated with greater antidepressant effects in the one-week period post-treatment in individuals with TRBD.

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...

TEST for Major Depression

Bethesda, Maryland
Background: People with TRD are often helped by electroconvulsive therapy (ECT). But ECT can affect memory and thinking. Researchers want to study a treatment called TEST that uses less electricity. Objective: To study the safety and feasibility of TEST and assess its antidepressant effects. Eligibility: Adults aged 25-64 with major depression that has not been relieved by current treatments. Design: Participants will be admitted to the NIH Clinical Center for 5-18 weeks over 2-3 treatment phases. Their medications may be adjusted. Participants will be interviewed about their depression, side effects, and other treatments they are receiving. They will complete questionnaires. They will give blood and urine samples. Their brain waves and heart rhythm will be recorded. They will take tests of memory, attention, mental functioning, and thinking. Participants will have magnetic resonance imaging (MRI) scans of the head and brain. They will lie on a table that slides in and out of the scanner. Pictures of brain chemicals will also be taken. They may complete tasks during the MRI. Participants will receive TEST and/or sham treatments. They may receive optional ECT. An intravenous catheter will be placed in an arm vein to receive general anesthesia. Two electrodes will be placed on the front of their head. An electric current will be passed from the ECT machine through the electrodes. For sham treatments, they will not receive the electric current. Their breathing, heart rate, brain function, blood pressure, and body movements will be measured. Participants will have 7 follow-up visits over 6 months. Visits can be done via telehealth. Participation will last for up to 42 weeks.

Approximately four thousand Canadians die by suicide every year, and suicide is the second leading cause of death in youth and young adults (15-34 years). Most people with depression experience thoughts of suicide and many will also plan and/or attempt suicide at some time in their life. There is an urgent need for new scalable treatments that can effectively reduce suicidality in people with depression. Cognitive behavioural therapy (CBT) reduces suicidal thoughts and behaviours, and can be delivered through the internet (i-CBT) making it more accessible and scalable. However, i-CBT has not been shown to rapidly reduce suicidal thoughts and behaviours (suicidality), such as within 24 hours. IV ketamine on the other hand has been shown to rapidly reduce thoughts of suicide, but not suicidal behaviours. Therefore, combining i-CBT with IV ketamine may be more effective reducing suicidality than i-CBT treatment with a control treatment. The investigators propose a 13-week, multi-site, study that looks at how combining i-CBT and IV ketamine treatment will affect suicidality in individuals with depression who have recently experienced suicidal thoughts and/or behaviours, but have not responded to previous treatment. All 110 participants will receive a weekly session of i-CBT for 13 weeks, but half will be randomly assigned to also receive six IV ketamine treatments or six IV midazolam treatments (control treatment) over the first initial 30 days. The investigators will measure changes in suicidal thoughts and behaviours before drug treatment and at the primary endpoint (i.e.,day 30), and after 3 months (i.e. Day 91) of the starting treatment.

The CogniTReaD study is a pilot clinical trial that will compare the effects of active accelerated bilateral sequential theta burst stimulation (absTBS) and sham or inactive treatment. The goal is to see if absTBS can help older adults with treatment-resistant depression (TRD) by looking at dual-task cost and mood, as well as other cognitive functions, anxiety levels, quality of life, and physical performance, while also checking for any treatment side effects. The study will recruit participants who will receive different study treatments in a specific order. The study will be double-blinded, meaning neither the participants nor the researchers will know who is receiving which treatment. The study will include people who are 50 years old or older and diagnosed with treatment-resistant depression with at least a moderate severity of depression. This study seeks to discover if absTBS can modify a dementia risk marker (i.e., dual-task cost and depression) in older patients with TRD, and to determine the effect size for larger investigations in the future.

Our hypothesis is that targeted propofol infusion in treatment-resistant depressed patients will induce slow wave activity during sedation and augment subsequent sleep slow wave activity. We will recruit 15 participants for this open label single arm Phase I trial. All participants will undergo two propofol infusions 2-6 days apart, with each infusion maximizing expression of EEG slow waves. To minimize bias, there will be no specific gender or ethnic background consideration for enrollment. This will be a single site investigation at Washington University Medical Center.

Frequently Asked Questions

How much do Treatment Resistant Depression clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Treatment Resistant Depression clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Treatment Resistant Depression trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Treatment Resistant Depression is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Treatment Resistant Depression medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Treatment Resistant Depression clinical trials ?

Most recently, we added Nitrous Oxide for Acute Suicidality, rTMS for Depression and TMS vs ECT for Depression to the Power online platform.
