Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43851   clinical trials with a EudraCT protocol, of which   7283   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    to evaluate the efficacy of gantenerumab compared with placebo administered to patients by SC injection over 100 weeks as measured by the following co-primary endpoints (final outcome assessment 4 weeks after the final dose):
    • Cognition measured by the Alzheimer’s Disease Activity Scale−Cognitive (ADAS-Cog) (13-item)
    • Function assessed by the Alzheimer’s Disease Cooperative Study−Activities of Daily Living (ADCS-ADL)
    E.2.2Secondary objectives of the trial
    1. to evaluate the benefits of gantenerumab versus placebo administered to patients by SC injection over 100 weeks on slowing clinical decline and disease progression by assessing the following:
    • Time to clinically evident decline
    • Chance from baseline at Week 104 in CDR-SB
    • ADAS-Cog responder
    • Disease pathology biomarkers
    2. Additional secondary endpoints
    · Global: Effect on severity of dementia and global measures of cognition and function
    · Cognition: Effect on cognition
    · Behavioar: Effect on behavioral and neuropsychological symptoms of AD
    · Other AD symptoms and effects: Effect of gantenerumab on health-related QoL, patient-individualized goal achievement (sites in English- and French-speaking countries only), on caregiver emotional well-being, on the amount of assistance patients with dementia require in performing daily activities
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    WN28745-PET Substudy, version 1, dated 19-Nov-2013

    Title: PET IMAGING SUBSTUDY ASSOCIATED WITH: A PHASE III, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PARALLEL-GROUP, MULTICENTER, EFFICACY, AND SAFETY STUDY OF GANTENERUMAB IN PATIENTS WITH MILD ALZHEIMER’S DISEASE

    The primary objective of the WN28745-PET substudy is to assess changes in amyloid load over time using florbetapir in patients enrolled in Study WN28745 who are treated with gantenerumab (RO4909832) or placebo. This patient population has probable mild AD (based on NINCDS/ADRDA criteria) or probable major NCD due to AD of mild severity (based on the DSM-5 criteria)

    The secondary objective of this substudy is to assess the concordance between positivity or negativity on CSF Aβ1−42 testing at entry in Study WN28745 and amyloid PET visual read in the WN28745-PET substudy.

    WN28745-Cardiac PET Substudy, Version 1, dated dd.mm.yyyy
    Title: CARDIAC PET IMAGING SUBSTUDY ASSOCIATED WITH: A PHASE III, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PARALLEL-GROUP, MULTICENTER, EFFICACY AND SAFETY STUDY OF GANTENERUMAB IN PATIENTS WITH MILG ALZHEIMER'S DISEASE
    Objectives: The primary objective of this cardiac PET substudy is to assess changes in amyloid load in heart over time using florbetapir F18 in patients enrolled in the main study and the brain only PET substudy who are treated with gantenerumab (RO4909832) or placebo. This patient population has probable mild AD (based on NINCDS / ADRDA criteria) or probable major NCD due to AD of mild severity (based on the DSM-5 criteria).

    Currently, the Sponsor does not have any plans to provide gantenerumab to patients after conclusion of the study or any earlier patient withdrawal. The Sponsor will evaluate the appropriateness of continuing to provide gantenerumab to study patients based on emerging data, which may include an interim analysis of Study WN28745. If the data are medically and statistically significant, the Sponsor may amend the protocol to continue to provide the drug in an open-label extension study to patients.
