Safety Study of Sertindole Versus Risperidone Under Normal Conditions of Use (SCoP)

Sertindole Versus Risperidone Safety Outcome Study: a Randomised, Partially-blinded, Parallel-group, Active-controlled, Post-marketing Study

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.

Study Overview

• Status: Completed
• Conditions: Schizophrenia
• Intervention / Treatment: Drug: Sertindole; Drug: Risperidone

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Sertindole; Normally in the range of 4 to 20 mg/day	Drug: Sertindole; 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; Other Names: Serdolect
Active Comparator: Risperidone; Normally in the range of 2 to 8 mg/day	Drug: Risperidone; 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; Other Names: Risperdal

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With All-cause Mortality	The analysis was based on all deaths from the Whole Randomised Treatment (WRT)+30 days period and the Only Randomised Treatment (ORT) period, respectively	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 Outcome: Number of Participants With Cardiac Events, Including Arrhythmias, Requiring Hospitalisation	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	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

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cause-specific Mortality: Number of Participants With Cardiac Deaths - ISC	The analysis was based on all deaths from the WRT+30 days period using the classification performed by the ISC. The ISC reviewed and classified those adverse events which resulted in death or hospitalisation or were possible suicide attempts and this review was blinded to exposure. The definition of cardiac death was intentionally wide; sudden or unexplained deaths were assumed to be cardiac if there was no non-cardiac explanation. To ensure consistent evaluation and classification, the ISC decided a priori to classify all instances of self harm as possible suicide.	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
Cause-specific Mortality: Number of Participants With Completed Suicides - ISC	The analysis was based on all deaths from the WRT+30 days period using the classification performed by the ISC. The ISC reviewed and classified those adverse events which resulted in death or hospitalisation or were possible suicide attempts and this review was blinded to exposure. The definition of cardiac death was intentionally wide; sudden or unexplained deaths were assumed to be cardiac if there was no non-cardiac explanation. To ensure consistent evaluation and classification, the ISC decided a priori to classify all instances of self harm as possible suicide.	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
Cause-specific Mortality: Number of Participants With Other Than Cardiac Deaths and Completed Suicides - ISC	The analysis was based on all deaths from the WRT+30 days period using the classification performed by the ISC. The ISC reviewed and classified those adverse events which resulted in death or hospitalisation or were possible suicide attempts and this review was blinded to exposure. The definition of cardiac death was intentionally wide; sudden or unexplained deaths were assumed to be cardiac if there was no non-cardiac explanation. To ensure consistent evaluation and classification, the ISC decided a priori to classify all instances of self harm as possible suicide.	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
Cause-specific Mortality: Number of Participants With Cardiac Deaths - MedDRA	The analysis was based on all deaths from the WRT+30 days period using the classification based upon the Medical Dictionary for Regulatory Activities (MedDRA) terminology, that is, as reported by the investigator	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
Cause-specific Mortality: Number of Participants With Completed Suicides - MedDRA	The analysis was based on all deaths from the WRT+30 days period using the classification based upon MedDRA terminology, that is, as reported by the investigator	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
Cause-specific Mortality: Number of Participants With Other Than Cardiac Deaths and Completed Suicides - MedDRA	The analysis was based on all deaths from the WRT+30 days period using the classification based upon MedDRA terminology, that is, as reported by the investigator	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
Number of Participants With Suicide Attempts (Fatal and Non-fatal) - ISC	The analysis was based on all suicides and suicide attempts from the WRT+30 days period using the classification performed by the ISC. The ISC reviewed and classified those adverse events which resulted in death or hospitalisation or were possible suicide attempts and this review was blinded to exposure. The definition of cardiac death was intentionally wide; sudden or unexplained deaths were assumed to be cardiac if there was no non-cardiac explanation. To ensure consistent evaluation and classification, the ISC decided a priori to classify all instances of self harm as possible suicide.	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
Number of Participants With Suicide Attempts (Fatal and Non-fatal) - MedDRA	The analysis was based on all suicides and suicide attempts from the WRT+30 days period using the classification based upon MedDRA terminology, that is, as reported by the investigator	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
Number of Participants With Hospitalisations, Excluding Hospitalisations Related to the Primary Psychiatric Disease	The analysis was based on time from start of study drug to first hospitalisation during the WRT+30 days period	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
Number of Participants With Discontinuation of Treatment for Any Reason Other Than Study Closure	The analysis was based on time from start of study drug until stop of study drug for any reason other than sponsor closure of the study	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
