      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.

      Transcranial Magnetic Stimulation for Depression

      Indianapolis, Indiana
      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

      Minocycline for Treatment-Resistant Depression

      Toronto, Ontario
      Major depressive disorder (MDD) is a leading cause of disability worldwide. Up to 50% of patients experience treatment resistant depression (TRD), which accounts for a vast majority of disease burden. Current medications for TRD have limited efficacy and can be associated with intolerable side effects. Therefore, there is a need for finding new treatment targets. Accumulating evidence suggests some patients with MDD including those with TRD, display brain inflammation. Thus, patients with TRD may benefit from medications that can reduce this inflammation. Minocycline is an antibiotic which can cross the blood-brain barrier and has effects on several systems implicated in depression. The principal investigator led the first pilot study of minocycline as an add-on treatment in TRD demonstrating that it led to a significant reduction in depressive symptoms compared to placebo and these findings require replication in a larger sample to confirm the efficacy and tolerability of this treatment approach. This study is a 12 week, double-blind, placebo-controlled trial of minocycline as add-on treatment for patients suffering from a major depressive episode who have failed to respond to antidepressant treatment, confirmed by the Structured Clinical Interview for DSM-5 (SCID-5) and the Antidepressant Treatment History Form (ATHF) at screening. After screening and randomization to the two parallel arms of the trial, 50 patients will receive minocycline added to treatment as usual (TAU) and 50 patients will receive placebo added to TAU. Clinical assessment will include the Hamilton Depression Rating Scale (HRSD-17), Clinical Global Impression scale (CGI), World Health Organization Quality of Life Short Form (WHOQOL-BREF), and Generalized Anxiety Disorder scale (GAD-7), administered at each study visit (baseline, week 2, 6, and 12). Side effects checklists will be undertaken at each visit. Minocycline will be started at 100 mg once daily and will be increased to 100 mg twice daily at two weeks. Secondary outcomes include inflammatory biomarkers measured at baseline, weeks 6 and 12. This trial will provide further evidence of minocycline's efficacy and acceptability as a treatment option for patients with TRD and provide insights into its mechanism of action.

      Psilocybin-Assisted Psychotherapy for Depression

      Toronto, Ontario
      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.

      rTMS for Major Depressive Disorder

      Toronto, Ontario
      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).

      Theta-Burst Stimulation for Bipolar Disorder

      Toronto, Ontario
      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.

      Ketamine + Virtual Reality for Depression

      Toronto, Ontario
      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".

      Psilocybin for Depression

      Toronto, Ontario
      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.

      Treatment-Resistant Depression PatientAge: 54

      "I tried Prozac, Lamictal, TMS, a psychotherapy, and mindfulness meditation. These treatments provided limited relief. I hope for a new treatment that will be more effective. Looking for something that lasts long-term so that I can get my life back."

      HY
      Depression PatientAge: 63

      "I've tried 8 or 9 different combinations of antidepressants (SSRI, SNRI, etc) + antipsychotics, mood stabilizers, anxiolytics... I’ve been through on- and off-label treatments, I've had at least 4 serious side effcts in the 10 years I've been on antidepressants. I've done PGx testing for genetic markers, too. My experience finding appropriate treatment has been lonely, exhausting. I'd love to participate in something that helps others like me."

      HZ
      Treatment-Resistant Depression PatientAge: 31

      "I’ve tried so many drugs and treatments for depression it won’t go away or if it does it just comes back. I want to help others who may have this awful condition while also helping myself. If something new works for me, maybe it'll work for other people too."

      WK
      Depression PatientAge: 56

      "I'm taking a medication for anxiety and it's not helping/working. I want to try and find something that would help with my anxiety. My research brought me to clinical trials."

      Psilocybin for Depression in Autism

      Toronto, Ontario
      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)

      Deep TMS for Depression

      Toronto, Ontario
      The goal of this clinical trial is to test whether an accelerated deep Transcranial Magnetic Stimulation (dTMS) protocol can reduce depressive symptoms in older adults (ages 60-85) with Major Depressive Disorder (MDD) who have not tolerated or responded to antidepressant medications. The study will evaluate whether accelerated dTMS administered over 5 consecutive days is safe and well-tolerated in this population, and whether it produces greater reductions in depressive symptoms compared to placebo stimulation.

      Transcranial Magnetic Stimulation for Depression

      Toronto, Ontario
      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.

      Psilocybin for Bipolar Depression

      Toronto, Ontario
      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.

      HNK for Treatment-Resistant Depression

      Bethesda, Maryland
      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. ...

      Theta Burst Stimulation for Depression

      Toronto, Ontario
      The purpose of this trial is to compare the treatment efficacy (improvement in depressive symptoms) of accelerated TBS protocol (where participants receive multiple TBS treatments daily) to conventional TBS protocol (where participants receive a single TBS treatment daily) in late life depression. In addition, the study also aims to determine if specific patterns of stimulation are more or less effective. To do this, all participants will receive active treatments, but some of the participants in this study will receive accelerated TBS and some will receive once daily TBS.

      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 Psilocybin for Depression, NRX-101 + TMS for Treatment Resistant Depression and Nitrous Oxide for Depression to the Power online platform.

      What do the "Power Preferred" and "SuperSite" badges mean?

      We recognize research clinics with these awards when they are especially responsive to patients who apply through the Power online platform. SuperSite clinics are research sites recognized for a high standard of rapid and thorough follow-up with patient applicants. Meanwhile, Power Preferred clinics are the top 20 across the entire Power platform, recognized for their absolute top patient experience.

      Which clinics have received Power Preferred and SuperSite awards recruiting for Treatment Resistant Depression trials?

      The Treatment Resistant Depression clinics currently recognized as Power Preferred are: Adams Clinical in Watertown, Massachusetts The Treatment Resistant Depression clinics currently recognized as SuperSites are: Preferred Research Partners, Fayetteville in Fayetteville, Arkansas
