Schizophrenia
Conditions
Brief summary
The purpose of the study is to determine whether there is an increased all-cause mortality in sertindole-treated patients in comparison to patients treated with a well-known antipsychotic (risperidone) when used under normal marketed conditions in the treatment of schizophrenia.
Detailed description
The Committee for Medicinal Products for Human Use (CHMP) requested a post-marketing study to ascertain that the favourable benefit-risk profile and low mortality rates seen in the clinical studies with sertindole would not be offset by higher mortality rates when sertindole was used under more normal conditions of use. It was recognised that, in a clinical trial setting, strict patient selection and monitoring could lead to higher compliance in patient management and thereby to a lower mortality rate. Study 99824 was therefore designed in collaboration with the CHMP as an open-label, randomised study with minimum study management that focused on mortality and general patient safety. The duration of the treatment period was not fixed. No efficacy measures were included.
Interventions
Sertindole was supplied as 4, 12, 16, and 20 mg tablets. The start and maintenance dosages as well as dose titration were set by the investigator, in accordance with the national Summary of Product Characteristics (SPC) for sertindole; in countries where sertindole was not marketed, the European Union (EU) SPC applied (all national and EU SPCs were essentially identical). Recommended dose range: 12 to 20 mg/day. The investigators were instructed to contact H. Lundbeck A/S if they deemed it necessary to increase the dose of sertindole to 24 mg/day, which was allowed in exceptional cases
Risperidone was supplied as 1, 2, 3, and 4 mg tablets. The start and maintenance dosages as well as dose titration were set by the investigator, in accordance with the national SPC for risperidone. Recommended dose range: 2 to 8 mg/day

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With All-cause Mortality | As study design allowed patients to continue study drug until the study was closed, many patients were followed for several years, with an overall median time period of approximately 14 months | The analysis was based on all deaths from the Whole Randomised Treatment (WRT)+30 days period and the Only Randomised Treatment (ORT) period, respectively |
| Second Primary Outcome: Number of Participants With Cardiac Events, Including Arrhythmias, Requiring Hospitalisation | As study design allowed patients to continue study drug until the study was closed, many patients were followed for several years, with an overall median time period of approximately 14 months | Second primary endpoint: a serious adverse event where the patient was hospitalised and for which the Independent Safety Committee (ISC) classified the event as a cardiac event with documented arrhythmia. The analysis of this outcome was not performed due to low number of events. The presented analysis is a replacement analysis using all cardiac events, including arrhythmias, that required hospitalisation |
