About this study

Schizophrenia (SZ) affects approximately 4.5 million people across the European Union (EU) and is associated with annual healthcare and societal costs of 29 billion Euros. The impact on the daily life of patients is huge, ranging from frequent relapses and hospitalisations, the inability to maintain a job or continue scholing, to a low quality of life, impaired cognitive functioning, suicidal ideation and an increase morbidity rate, next to the large burden for carers 1. When diagnosed with schizophrenia or related disorder, patients are commonly prescribed antipsychotics. One-third of the schizophrenia patients are regarded treatment-resistant (TR), meaning that at least two antipsychotic trials have failed. Typically, clozapine is prescribed for TR patients, which is effective for approximately 40% of patients. Clozapine is among the most effective treatments, with the lowest all-cause mortality. Although it is among the most effective antipsychotics, it is generally not used earlier in the illness course due to a small risk of severe neutropenia/agranulocytosis, which is why patients treated with clozapine are intensely monitored. However, this small risk outweighs the burden of not receiving an effective treatment. Since clozapine is among the most effective treatments, this leads to the research question whether earlier initiation of third-line treatment ('early intensified' pharmacological treatment; EIPT) would be more beneficial than the current second-line treatment…
