Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Alzheimer's Disease Assessment Scale-Cognitive Subscale 11 Item (ADAS-Cog11) Total Score After 12 Weeks of Treatment [On day 1 (visit 2, baseline) and day 85 (end of trial)]

    The ADAS-Cog11 is an 11-item cognitive subscale that objectively measures memory, language, orientation and praxis with a total score range of 0 to 70, with lower scores indicating less severe impairment. A negative change indicates an improvement from baseline. Multiple comparison procedures and modelling (MCPmod) in combination with mixed model repeated measures (MMRM) is used for primary analysis of the primary endpoint. MMRM included fixed, categorical covariates of treatment, visit, baseline Mini Mental State Examination MMSE (>=20, <20) and treatment-by-visit interaction, as well as the continuous fixed covariates of baseline and baseline-by-visit interaction. Patient was considered as random effect. The unstructured covariance structure was used to model the within patient measurements. The same MMRM model used in the primary analysis is used for the secondary analysis of the primary endpoint.

Secondary Outcome Measures

  1. Change From Baseline in the Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) Score After 12 Weeks of Treatment [On day 1 (visit 2, baseline) and day 85 (end of trial)]

    Change from baseline in the ADCS-ADL score after 12 weeks of treatment is presented. The ADCS-ADL is a rating scale used to assess basic and instrumental activities of daily living. In the full version of the scale, 23 items are rated by the investigator using information supplied by the caregiver. Each item has a score range varying from 0-3 to 0-5. The sum score could range from 0 to 78, with higher scores indicating less severe impairment. A positive change indicates an improvement from baseline. Abbreviation: MMSE = Mini Mental State Examination

  2. Clinician's Interview-Based Impression of Change (CIBIC+) Score After 12 Weeks of Treatment [On day 1 (visit 2, baseline) and day 85 (end of trial)]

    Clinician's Interview-Based Impression of Change (CIBIC+) score is based on semi-structured interview covering domains of function and cognition. It additionally requires the assessment of psychiatric signs and symptoms. The patient and their caregiver are interviewed and questioned by the clinician. Change rate is based on an unanchored 7-point scale (with 0 being not assessed, 1-3 being very much improved to minimally improved, 4 being no change, and 5-7 being minimally worse to very much worse). For the ANCOVA model, the baseline value for CIBIC+ is represented by CIBIS which is clinician's interview-based impression of severity score (scores range from 0-7, with 0 being not assessed, 1 being normal, and 7 being most extremely ill) in order to adjust for potential baseline heterogeneity. Abbreviation: MMSE = Mini Mental State Examination

Participant Flow

Recruitment Details This is a multi-centre, double-blind, parallel-group, randomised controlled study to investigate efficacy and safety of orally administered BI 425809 during a 12-week treatment period compared to placebo in patients with cognitive impairment due to Alzheimer's Disease.
Pre-assignment Detail Subjects were screened prior to participation and attended a specialist site which ensured that they strictly met all inclusion/exclusion criteria. Subjects were not to be allocated to a treatment group if any of the criteria were violated. One subject was randomized by error via Interactive Response Technology (IRT) but never took a drug.

2. Secondary Outcome
Title Change From Baseline in the Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) Score After 12 Weeks of Treatment
Description Change from baseline in the ADCS-ADL score after 12 weeks of treatment is presented. The ADCS-ADL is a rating scale used to assess basic and instrumental activities of daily living. In the full version of the scale, 23 items are rated by the investigator using information supplied by the caregiver. Each item has a score range varying from 0-3 to 0-5. The sum score could range from 0 to 78, with higher scores indicating less severe impairment. A positive change indicates an improvement from baseline. Abbreviation: MMSE = Mini Mental State Examination
Time Frame On day 1 (visit 2, baseline) and day 85 (end of trial)

Outcome Measure Data

Analysis Population Description
Full analysis set (FAS): all randomised patients who were treated with at least one dose of trial medication and had a baseline and at least one corresponding post-baseline on-treatment efficacy assessment for any efficacy endpoint. FAS was used for efficacy analyses.

3. Secondary Outcome
Title Clinician's Interview-Based Impression of Change (CIBIC+) Score After 12 Weeks of Treatment
Description Clinician's Interview-Based Impression of Change (CIBIC+) score is based on semi-structured interview covering domains of function and cognition. It additionally requires the assessment of psychiatric signs and symptoms. The patient and their caregiver are interviewed and questioned by the clinician. Change rate is based on an unanchored 7-point scale (with 0 being not assessed, 1-3 being very much improved to minimally improved, 4 being no change, and 5-7 being minimally worse to very much worse). For the ANCOVA model, the baseline value for CIBIC+ is represented by CIBIS which is clinician's interview-based impression of severity score (scores range from 0-7, with 0 being not assessed, 1 being normal, and 7 being most extremely ill) in order to adjust for potential baseline heterogeneity. Abbreviation: MMSE = Mini Mental State Examination
Time Frame On day 1 (visit 2, baseline) and day 85 (end of trial)
