MDMA for Schizophrenia

Los Angeles, California
Impaired social motivation, or "asociality," is a negative symptom of schizophrenia (SCZ) and a cause of significant functional impairment in the illness. Whereas many symptoms of schizophrenia can be treated with antipsychotic medications, deficits in social motivation persist, leading to significant social disability in patients. There is currently no effective treatment for this symptom of the illness. One promising and unexplored avenue to enhance social motivation in schizophrenia is ± 3,4-methylenedioxymethamphetamine (MDMA). MDMA is a psychostimulant that shares some pharmacological properties with amphetamines, but in addition, has pronounced pro-social effects, increasing the motivation to engage socially. In healthy volunteers, it produces feelings of empathy and closeness with others and increases attention to positive social cues, perhaps partly through its effects on the social bonding hormone, oxytocin. MDMA has shown promise in other psychiatric conditions such as PTSD. Thus, MDMA could offer a unique therapeutic benefit in patients with SCZ who suffer from impaired social motivation. The investigators plan to take the first step in testing MDMA as a treatment for these social deficits by testing the tolerability of the drug in patients with SCZ. This will be an open-label, ascending-dose, within-subject trial in which participants will receive 40mg, 80mg, or 120mg of MDMA. The doses will be administered in ascending order, but doses will be stopped if subjects experience moderate or greater psychotic symptoms at 24 hours. This trial will assess the tolerability of the drug in this population and guide in the selection of a maximum well-tolerated dose for future studies. The primary tolerability measure will be clinician-rated psychotic symptoms (disorganized speech, delusions, hallucinations) collected at 24 hours after MDMA administration. The results of this project will lay the foundation for further investigations of MDMA and other psychoactive compounds as a treatment for debilitating and difficult-to-treat social deficits in schizophrenia. Future studies will examine interactions between the effects of psychoactive compounds and nonpharmacologic psychosocial interventions targeting social symptoms.

Low social motivation is a significant symptom of schizophrenia and is a major cause of disability and suffering for many patients struggling with the illness. Social motivation refers to the drive to participate in or abstain from social activities. Many patients with schizophrenia evidence both decreased drive to seek positive social input (approach motivation) and heightened drive to avoid negative social input (avoidance motivation) compared to individuals without the illness. Despite the enormous burden of these deficits on patients, there are no medications that effectively treat impaired social motivation. Buprenorphine is an unusual drug that is used to treat opioid use disorder at higher doses and more recently, to treat depression and suicidality at lower doses. It is a unique opioid medication that has a compound action that gives it the potential to improve social motivation both by boosting approach motivation and by reducing avoidance motivation. The effects of low doses of buprenorphine have previously. been studied in healthy volunteers, showing that the drug enhances social motivation. These results in nonclinical volunteers suggest that buprenorphine may be a promising treatment for deficits in social motivation seen in some patients with schizophrenia. However, no previous studies have investigated the effects of buprenorphine on social motivation in this population. Here the effects of a low dose of buprenorphine (0.15mg) on social motivation in patients with schizophrenia (N=40) will be assessed. In this double-blind, cross-over, placebo-controlled study, participants will attend a 2-hour preparatory session and two 6-hour laboratory sessions, at which they will receive either placebo or buprenorphine. During expected peak drug effect they will complete validated tasks assessing social motivation. It is expected that buprenorphine will increase approach motivation and decrease avoidance motivation as measured by an attention bias task. The results of this study will lay the foundation for the clinical use of buprenorphine as the first medication to treat social deficits in schizophrenia.

The purpose of this study is to utilize the radioactive positron emission tomography (PET) tracer \[11C\]UCB-J to test the neural synaptic pruning hypothesis of schizophrenia. This imaging method allows for the quantification of synaptic density in the living human brain and has the unprecedented ability to directly examine the synaptic pathology underlying neuropsychiatric disease. The neural synaptic pruning hypothesis posits that a key pathogenic process of schizophrenia is the over-exuberant elimination of neural synapses during development. The confirmation of reduced synaptic density in schizophrenia as evidenced by \[11C\]UCB-J has the potential to lead to a number of ground-breaking clinical innovations, such as laboratory-based diagnostics and prognostics, and novel, disease-modifying treatments.

Why Other Patients Applied

"I've tried many medications that didn't work that well. I really really want to be better and function in society... a different kind of treatment could help."

FF
Schizophrenia PatientAge: 36

"I’ve been diagnosed with Schizoaffective Disorder for over 5 years now and not found much relief in medication. One I’ve tried helped a bit but the side affects were overwhelming. Hoping I can gain some relief from this disorder and help advance research as well!"

MX
Schizophrenia PatientAge: 44

"I'm willing to try anything to help improve and manage my schizophrenia in any way. I do my best each day to keep the hallucinations at bay. I no longer hear voices but I don't want them to come back either. Most medicine I've tried hasn't help very much."

ZC
Schizophrenia PatientAge: 39

"I would like to get a medication that has fewer side effects than the ones I've used. Many antipsychotics just make me numb or flat and I can't really think. Also I like the idea of helping in research to find better medications for schizephrenia."

VT
Schizophrenia PatientAge: 60

"I've tried lots of drugs and I still have symptoms. I'm not sure of my reality because the things I see and hear are still active. Maybe this will help one way or the other. I would be glad to help others in the future by testing a medication as well."

Over 60% of Veterans with serious mental illness have a service-connected disability that impairs their ability to work, go to school, and/or have successful personal lives. Although traditional treatments tend to focus on symptom remission, Veterans prioritize a range of treatment goals, including personal empowerment and gaining personally meaningful skills. Increasing Veteran-clinician collaboration can help effectively align care with each Veteran's goals and support an empowering therapeutic experience. This project will evaluate the effectiveness of a group-based intervention intended to increase Veterans' comfort, confidence, knowledge, and skills to collaborate with their treatment teams. Findings from this study will contribute important knowledge about this intervention's effectiveness and how to enhance its effectiveness, especially for Veterans from minoritized groups. If the decision-making intervention is effective, it would help Veterans with serious mental illness, and might also help Veterans with other chronic health conditions, like PTSD and chronic pain.

This study addresses the critical need for innovative therapeutic interventions in Veterans with serious mental illnesses (SMI) receiving care in VA Psychosocial Rehabilitation and Recovery Centers (PRRCs). The vast majority of individuals with SMI suffer from cognitive impairments, leading to chronic functional disability, and impaired outcomes, causing a significant strain on support networks and the VA healthcare system. This study aims to introduce an innovative mental health therapy, Targeted Cognitive Training (TCT), to Veterans struggling with serious mental illnesses (SMI). TCT works to improve basic sensory information processing and, ultimately, clinical, cognitive, and psychosocial functioning. By using EEG biomarkers to identify Veterans with SMI receiving care within VA Psychosocial Rehabilitation and Recovery Centers who are most likely to benefit from this treatment, and by understanding how best to implement this therapy, the investigators hope to enhance care and improve life quality for Veterans with SMI.

TMS for Schizophrenia

San Francisco, California
This randomized controlled trial in healthy controls (HC) and patients with schizophrenia (SZ) aims to examine 1) the underlying cognitive and neural cause of self-agency deficits in SZ; 2) the responsiveness to a novel navigated repetitive transcranial magnetic stimulation (nrTMS) target in the medial/superior prefrontal cortex (mPFC); and 3) how modulation of mPFC activity impacts the larger self-agency network to mediate changes in self-agency judgments. Our overall hypothesis is that increased mPFC excitability by active high-frequency nrTMS in HC and SZ will induce behavioral improvements in self-agency and neural changes in the larger self-agency network that will generalize to improvements in overall cognition, symptoms and daily functioning, and will likely lead to the development of new effective neuromodulation therapies in patients with schizophrenia.

Frequently Asked Questions

How much do Schizophrenia clinical trials in California 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 Schizophrenia clinical trials in California 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 Schizophrenia trials in California 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 in California for Schizophrenia 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 in California 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 Schizophrenia medical study in California?

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 Schizophrenia clinical trials in California?

Most recently, we added Collaborative Decision Skills Training for Serious Mental Illness, NBI-1117568 for Schizophrenia and Xanomeline + Trospium for Schizophrenia to the Power online platform.

Why is schizophrenia more common now?

Most studies show the yearly number of new schizophrenia cases hasn’t skyrocketed; it only feels more common because doctors now catch milder cases and people with the illness live longer, so more are counted at any one time. Modern lifestyle changes—growing up in crowded cities, high-potency cannabis use, migration stress, older parenthood, and ongoing poverty—do add modest risk for certain groups, nudging overall figures upward. Recognising these drivers guides prevention efforts like early screening, substance-use education, urban social support, and good prenatal care.

What is the best injection for schizophrenia?

There isn’t one “best” injection for everyone with schizophrenia. Doctors usually choose among long-acting injectables such as paliperidone (monthly to every 6 months), aripiprazole (monthly or every 2–3 months) or risperidone (every 2 weeks to monthly) based on which oral version has helped you before, how often you can come for shots, and which side-effects you’re most sensitive to. Your psychiatrist will review these factors—plus cost, other health conditions and personal preference—to decide which LAI is the safest and most effective fit for you.

Who is most likely to recover from schizophrenia?

Research shows the best odds of meaningful recovery occur in people who get treatment quickly after their first symptoms, keep taking medication and using psychological/rehab supports, avoid alcohol or drugs, and have steady family or community support; women and those whose illness starts later in their 20s also tend to fare somewhat better, but these fixed factors matter less than the modifiable ones above. In short, while anyone with schizophrenia can improve, the combination of early intervention, sticking with care, healthy lifestyle, and strong social ties makes the biggest difference in who recovers.

Is schizophrenia inherited from mother or father?

Schizophrenia risk is passed down through many genes that you receive from both parents, and large studies do not show a consistent advantage of either the mother’s or the father’s side. Compared with the 1 % lifetime risk in the general population, the chance rises to about 10 % if one parent has schizophrenia and up to 40 % if both do; factors such as pregnancy complications, cannabis use, severe stress, or very advanced paternal age can add to that risk. Families with a history of the illness may benefit from genetic counselling and early mental-health check-ups during adolescence so any warning signs can be managed promptly.

How is schizophrenia viewed in China?

China does not have a single view of schizophrenia: in big cities many people now regard it as a treatable brain disorder, but in rural areas it may still be linked to spirit possession or seen as a source of family “shame,” so relatives often hide the illness and shoulder most care. High stigma persists because unusual behaviour is felt to threaten the family’s “face,” yet government programs such as the nationwide 686 follow-up system and the 2013 Mental-Health Law are expanding hospital care, community visits, and public education. Overall, attitudes are gradually shifting toward acceptance, but progress is uneven and support for both patients and their families remains a work in progress.

Are there any clinical trials being done for schizophrenia?

Yes—dozens of studies are actively recruiting worldwide, ranging from novel medicines like KarXT (muscarinic M1/M4 agonist), ulotaront (TAAR1 agonist), and roluperidone (aimed at negative symptoms) to long-acting weekly risperidone implants (TV-46000) and app-based cognitive programs. You can see real-time listings, eligibility criteria, and locations by typing “schizophrenia” into ClinicalTrials.gov or the EU Clinical Trials Register and then reviewing the options with your psychiatrist to weigh potential benefits, risks, and travel demands.

What is the biggest problem of schizophrenia?

Schizophrenia isn’t defined by one “biggest problem”; clinicians group its effects into positive symptoms (hallucinations/delusions), disorganization, negative symptoms (loss of drive, social withdrawal) and cognitive deficits. Studies show that after acute psychosis is controlled, the lasting obstacles to working, studying and maintaining relationships are usually the negative and cognitive symptoms, so effective care pairs antipsychotic medication with therapies and skills training that rebuild motivation, thinking and daily-living abilities.

Who has the highest rate of schizophrenia?

Worldwide, the single highest recorded rates occur in young adult Black Caribbean or Black African men who are migrants (or children of migrants) living in large urban areas; their chance of developing schizophrenia can be 4- to 9-times higher than that of white native-born residents. In general, men have a modestly higher risk than women (about 1.4 : 1), but factors such as minority or migrant status and growing up in a high-density city raise risk far more than sex alone.

What's the latest schizophrenia can develop?

Most people who develop schizophrenia do so between their late teens and early 30s, but experts recognise “late-onset” cases appearing at 40-60 and a rarer “very-late-onset schizophrenia-like psychosis” beginning after 60. Because psychosis this late in life is uncommon and can mimic problems such as dementia, stroke, or severe depression, anyone with new hallucinations or delusions at these ages should be evaluated promptly by a mental-health professional and a physician to sort out the cause and start the right treatment.
