Eligibility
Inclusion criteria
Inclusion criteria: Open-label treatment period (initial 28 weeks): • The patient has completed Visit 7 (Completion Visit) in the lead-in double-blind, placebo controlled clinical studies 14861A or 14862A. Open-label treatment period with memantine (sub-study): Major inclusion criteria at Baseline III: * The patient has completed Visit 6 [(i.e., the open-label treatment period (initial 28-week period)]. * The patient has a MMSE score at Visit 6 not greater than 19 in accordance with the memantine label/summary of product characteristics (SmPC). * The patient, according to the judgement of the investigator, requires initiation of treatment with memantine as per locallabei/SmPC/treatment guidelines. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 265 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 1505
Exclusion criteria
Exclusion criteria: • The patient has a moderate or severe ongoing adverse event from the lead-in study considered a potential safety risk by the investigator. • The patient has experienced seizures before Completion Visit in the lead-in study. • The patient has evidence of clinically significant disease. • The patient's donepezil treatment is likely to be interrupted or discontinued during the study. • The patient is receiving therapy with another AChEI or memantine. Open-label treatment period with memantine (sub-study): Major exclusion criteria at Baseline III: * The patient exhibits an increase in MMSE score by 3 points or more at Visit 6 from Baseline II. * The patient has a moderate or severe on-going adverse event from the open-label treatment period (initial 28-week period) considered a potential safety risk by the investigator. * The patient has a previous history of testing positive for hepatitis B surface antigen (HBsAg), or hepatitis C virus / antibodies (anti-HCV) AND had abnormal ALT, AST or bilirubin during the open-label treatment period (initial 28-week period). * The patient has tested positive for hepatitis B surface antigen (HBsAg), or hepatitis C virus /antibodies (anti-HCV) for the frrst time within the last 6 months prior to the Visit 6 in the open-label treatment period (initial 28-week period). * The patient has one or more clinical laboratory test values outside the reference range, based on the latest available blood and urine sample results during the open-label treatment period (initial 28-week period), that are of potential risk to the patient's safety, or the patient has according to the latest available blood sample: - a serum creatinine value >1.5 times the upper limit of the reference range, or - a serum total bilirubin value >1.5 times the upper limit of the reference range, or - a serum alanine aminotransferase (AL T) or aspartate aminotransferase (AST) value >2 times the upper limit ofthe reference range.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Open-label treatment period (initial 28 weeks): To evaluate the long-term safety and tolerability of idalopirdine as adjunctive therapy to donepezil in patients with mild-moderate AD. Open-label treatment period with memantine (sub-study): To evaluate the safety and tolerability of concomitant treatment with idalopirdine, memantine and donepezil in patients with AD.;Secondary Objective: Open-label treatment period (initial 28 weeks): To evaluate the disease development during long-term treatment with idalopirdine as adjunctive therapy to donepezil. Open-label treatment period with memantine (sub-study): To evaluate the disease development during concomitant treatment with idalopirdine, memantine and donepezil in patients with AD.;Primary end point(s): • Safety: Number of adverse events • Tolerability: Number of withdrawals;Timepoint(s) of evaluation of this end point: Up to 28 weeks and a 4-week safety follow-up | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Change in cognition: Change in Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog) total score • Change in global impression: Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-CGIC) score • Change in functioning: Change in Alzheimer's Disease Cooperative Study - Activities of Daily Living Inventory (ADCS-ADL23) total score • Change in behavioural disturbance: Change in Neuropsychiatric Inventory (NPI) total score • Change in cognitive aspects of mental function: Change in Mini Mental State Examination (MMSE) • Risk of Suicidality Using C-SSRS Scores: Columbia Suicide Severity Rating Scale (C-SSRS);Timepoint(s) of evaluation of this end point: Baseline and Week 28 for all, except for Risk of Suicidality which is up to week 28. | — |
