Primäre Endpunkte (Datenquelle: WHO)

Main Objective: Efficacy:evaluate crenezumab 60 mg/kg compared with placebo when admin. by IV infusion q4w over 100 wks as measured(final outcome assessment at Wk 105,4 wks after the final dose)Change from baseline on CDR-sum of boxes
Safety:evaluate the safety of crenezumab compared with placebo in patients with prodromal to mild AD on the basis of the follow. endpoints
•Nature,frequency,severity and timing of adverse events and serious adverse events
•Physical and neurologic examinations,vital signs,blood tests,ECGs,Columbia Suicide Severity Rating Scale,Non-serious adverse events of special interest, specific. pneumonia
•Adverse events,as assessed by magnetic resonance imaging:amyloid related imaging abnormalities edema/effusion,amyloid related imaging abnormalities hemosiderin deposition
•The immunogenic potential of crenezumab through measurement of antibodies directed against crenezumab and other components of the drug product,assessment of their relationship with other outcome measures
;Secondary Objective: Efficacy: secondary efficacy objective for this study is to evaluate the benefits of crenezumab versus placebo administered to patients by IV infusion over 100 weeks through assessment of the following endpoints
•Cognition, as measured by the ADAS-Cog (subscale) 13 (ADAS Cog 13)
•Effect on severity of dementia, assessed using the CDR-Global Score (CDR GS)
•Effect on cognition, assessed using the MMSE, ADAS-COG12
•Effect on function, assessed using the ADCS-ADL instrumental subscale (ADCS iADL) and ADCS-ADL total score
•Effect on behavioral and neuropsychological symptoms of AD, assessed using the Neuropsychiatric Inventory Questionnaire (NPI-Q)
•Effect of crenezumab on health-related quality of life (QoL), assessed using the Quality of Life-Alzheimer’s Disease scale, caregiver burden, assessed using the Zarit Caregiver Interview for Alzheimer’s Disease scale and on health outcomes in patient and caregiver as measured by EQ-5D


;Primary end point(s): To evaluate crenezumab 60 mg/kg compared with placebo when administered by IV infusion q4w over 100 weeks as measured by the following primary endpoint (final outcome assessment at Week 105, 4 weeks after the final dose): Global outcomes, as assessed by the CDR SB
