This research study is for participants that have been diagnosed with intractable Obsessive -compulsive disorder (OCD). OCD is a persistent and oftentimes disabling disorder marked by unwanted and distressing thoughts (obsessions) and irresistible repetitive behaviors. OCD affects 2-3% of the US population, and is responsible for substantial functional impairment and increased risk of early death. The only established first-line treatments for OCD are cognitive-behavioral therapy (CBT) with exposure and response prevention and certain medications. About 30-40% of patients fail to respond and few experience complete symptom resolution. Up to 25% of patients have difficulty tolerating CBT and the risk of relapse after therapies remains large. For the most severe cases, neurosurgery (surgery in the brain), has long been the option of last resort. In this study the investigators want develop an adaptive Deep Brain Stimulation (aDBS) system to use in subjects with intractable (hard to control) OCD. Deep brain stimulation (DBS) remains investigational for OCD patients and is not considered standard therapy. DBS involves the surgical implantation of leads and electrodes into specific areas of the brain, which are thought to influence the disease. A pack implanted in the chest, called the neurotransmitter, keeps the electrical current coursing to the brain through a wire that connects the neurotransmitter and electrodes. It is believed DBS may restore balance to dysfunctional brain circuitry implicated in OCD. The goal of this study is to enhance current approaches to DBS targeting in the brain and to use a novel approach to find a better and more reliable system for OCD treatment. This current research protocol will focus on the completion of Phase II which will implant the RC+S system with ECoG paddles in 5 subjects.

This trial is testing a new treatment called Mindfulness-Based Cognitive Therapy (MBCT) for people with Obsessive-Compulsive Disorder (OCD) who haven't fully benefited from standard treatments. MBCT helps patients become more aware of their thoughts and feelings without reacting to them, which can reduce OCD symptoms. If successful, this approach could be used widely in clinical settings to help more people with OCD. Mindfulness-Based Cognitive Therapy (MBCT) has been shown to be effective in various mental disorders and is now being explored as a complementary treatment for OCD, particularly for those who do not fully benefit from standard treatments.

Cognitive behavioural therapy (CBT), incorporating exposure/response prevention (ERP) and cognitive therapy, is considered the gold-standard first-line treatment for obsessive-compulsive disorder (OCD). Because CBT is a psychological treatment that aims to change patterns of thinking and behaving, it may be that improvement in cognitive functioning before treatment starts could lead CBT to be even more effective. One area of research that has shown potential benefit for OCD sufferers is rTMS. rTMS is a non-invasive procedure that uses pulses of energy to stimulate regions of the brain. Brief treatment with rTMS has shown to improve attention, memory, and other aspects of cognitive functioning that may facilitate learning in CBT. The proposed study aims to provide a pilot test of the clinical effectiveness of adding brief rTMS prior to completing CBT for OCD. If rTMS can demonstrate enhancement of cognitive functioning, which in turn, can improve treatment response to CBT, then the findings could easily be translated into routine clinical care.

Psilocybin for OCD

Toronto, Ontario
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, feasibility, and clinical effects of psilocybin administration in those with OCD. Ten participants with treatment-resistant OCD will receive two doses of 25mg of psilocybin under supportive conditions, two weeks apart. The investigators hypothesize that two sessions of psilocybin 25mg administered under supportive conditions to participants with treatment-resistant OCD will lead to significant reductions in OCD symptoms.

Thought-Action-Fusion (TAF) is a cognitive bias that posits (1) having unwanted thoughts is morally equivalent to acting upon the thoughts (TAF-Moral; e.g., "Thinking about harming a child is as immoral as actually harming a child") and (2) having unwanted thoughts will increase the likelihood of the thoughts happening in real life (TAF-Likelihood; e.g., "My mother will get into a car accident, because I thought about it"). Given its central role in the development and maintenance of OCD, TAF has emerged as a potential treatment target for obsessive-compulsive disorder (OCD). Previous research has demonstrated that TAF is indeed a malleable construct. This study aims to examine the effects of a multi-session, personalized cognitive bias modification (CBM) for thought-action-fusion (TAF) on improving obsessive-compulsive (OC) symptoms in a college sample.

Psilocybin for Depression

New Haven, Connecticut
The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significant symptom reduction and functional improvement from baseline symptom measurements (Visit 3) to 1-week (Visit 7), 4-weeks (Visit 8), and 6-weeks (Visit 9) post dosing. The investigators will recruit individuals with mood, anxiety, trauma, addictive, or related symptomatology, and who have functional impairment associated with these symptoms. A DSM-5 diagnosis is not required (nor is it an exclusion). The investigators will allow for comorbidity and only exclude based on psychological and physiological safety considerations. Critically, this approach will allow us to assess the tolerability of our interventions in individuals who would typically be excluded from efficacy studies due to various comorbid DSM-5 conditions. The investigators will employ an open-label study where participants will be given one dose of oral psilocybin 25mg. The investigators will also have follow-up visits at 1, 4, and 6 weeks and an optional long-term follow-up at 3, 6, and 12 months.

Frequently Asked Questions

How much do Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder clinical trials ?

Most recently, we added Deep Brain Stimulation for Obsessive-Compulsive Disorder, Deep Brain Stimulation for Obsessive-Compulsive Disorder and Virtual Reality for OCD to the Power online platform.
