What is the purpose of this trial?

This trial tests a new long-acting injectable form of lumateperone, a medication for treating schizophrenia and schizoaffective disorder. Researchers aim to determine the safety of this new version and how the body processes it. Different groups will receive various versions of the treatment to identify the best option. This trial may suit individuals who have been stable with schizophrenia or schizoaffective disorder for at least three months without severe symptoms. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new form of medication.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Is there any evidence suggesting that lumateperone long-acting injectable is likely to be safe for humans?

Research has shown that lumateperone is generally safe for humans. In past studies, participants using lumateperone long-acting injectable (LAI) forms reported few side effects, with many experiencing no major issues.

The FDA has already approved lumateperone for treating schizophrenia, indicating its general safety. Although this trial is in the early stages, FDA approval suggests it has undergone safety testing in similar treatments. However, new formulations can produce different effects.

Prospective trial participants should know that early-stage trials primarily focus on safety and treatment tolerance. Researchers closely monitor participants for any potential issues. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Lumateperone is unique because it offers a long-acting injectable option for treating schizophrenia, which could mean fewer doses and improved patient compliance compared to daily oral medications. Unlike traditional antipsychotics that primarily target dopamine receptors, lumateperone works through a novel mechanism by modulating serotonin and glutamate pathways as well, potentially offering a broader therapeutic effect. Researchers are excited because this could lead to better management of symptoms with fewer side effects, addressing significant unmet needs in schizophrenia treatment.

What evidence suggests that lumateperone long-acting injectable could be an effective treatment for schizophrenia?

Research has shown that lumateperone, the investigational treatment in this trial, effectively treats symptoms of schizophrenia. It alleviates positive symptoms like hallucinations and negative symptoms like social withdrawal. Studies also indicate it improves thinking and memory problems. Long-term evidence found that lumateperone reduced the risk of relapse by 63% in adults with schizophrenia compared to those not taking it, suggesting it may help prevent symptoms from returning. Overall, lumateperone is considered effective for managing various aspects of schizophrenia. Participants in this trial will receive different formulations of lumateperone to further evaluate its effectiveness. ^{2 3 5 6 7}

Published Research Related to This Trial

In a study of 301 outpatients with stable schizophrenia, lumateperone was found to be well tolerated, with only 45.5% experiencing treatment-emergent adverse events, most of which were mild or moderate, and a very low incidence of extrapyramidal symptoms (1.0%).

Patients switching to lumateperone showed significant improvements in metabolic parameters, such as reduced cholesterol and body weight, while maintaining stable schizophrenia symptoms, indicating its safety and efficacy compared to previous antipsychotic treatments.

In a study involving 10 patients with schizophrenia, lumateperone (ITI-007) demonstrated a mean dopamine D2 receptor occupancy of 39% after a 60 mg dose, which is lower than most traditional antipsychotics, potentially leading to fewer side effects.

Lumateperone was well-tolerated with no significant adverse effects, such as motor disturbances or increased prolactin levels, suggesting it may offer a safer treatment alternative for schizophrenia.

Lumateperone for the Treatment of Adults With Schizophrenia: a Systematic Review. Jawad, MY., Alnefeesi, Y., Ceban, F., et al.[2022]

Lumateperone (Caplyta®) is a newly approved medication for schizophrenia that works by blocking serotonin 2A receptors and has a unique mechanism involving partial agonism at presynaptic dopamine receptors and modulation of glutamate receptors, which may help address symptoms of the disorder.

Clinical trials (Phase II and III) suggest that Lumateperone's novel mechanism could offer benefits in treating schizophrenia, although it shares similarities with existing second- and third-generation antipsychotics.
