What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment.
Neuropsychological Test Battery (NTB) response, defined as change from baseline in total z-score after 12 weeks of treatment. The NTB Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean at baseline. Negative numbers indicate values lower than baseline and positive numbers indicate values higher than baseline. Change from baseline will be calculated as the post-baseline composite z-score minus the pre-treatment z-score, such that a positive change indicates an improvement from baseline
Measured: Baseline and 12 weeks
Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment From Two Twin Trials, Present 1289.5 (NCT02240693) and 1289.7 (NCT02337907)

Secondary outcomes (3)
Change From Baseline in ADCS-MCI-ADL (Alzheimer's Disease Cooperative Study/Activities of Daily Living for Patients With Mild Cognitive Impairment) Total Score After 12-week Treatment
Alzheimer's Disease Cooperative Study/Activities of Daily Living (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 can range from 0 to 78. Higher scores indicate better function.
Least Squares Mean is actually an adjusted mean change from baseline.
Measured: Baseline and 12 weeks
Change From Baseline in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) Total Score After 12-week Treatment
The CDR-SB is obtained through semi-structured interviews of patients and informants, and cognitive functioning was rated in 6 domains of functioning: memory, orientation, judgment and problem solving, community affairs, home and hobbies and personal care.
Each domain was rated on a 5-point scale of functioning as follows: 0-no impairment; 0.5-questionable impairment; 1-mild impairment; 2-moderate impairment and 3-severe impairment. Only personal care was scored on a 4-point scale without a 0.5 rating available. The higher the score, the greater the severity of dementia. Least Squares Mean is actually an adjusted mean change from baseline.
Measured: Baseline and 12 weeks
Change From Baseline in Alzheimer's Disease Assessment Scale-cognitive Subscale (ADAS-cog11) Total Score After 12-week Treatment
Alzheimer's Disease Assessment Scale-cognitive subscale (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. The greater the dysfunction, the greater the score. Least Squares Mean is actually an adjusted mean change from baseline.
Measured: Baseline and 12 weeks

Primary outcome
Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment.
Time frame: Baseline and 12 weeks
Neuropsychological Test Battery (NTB) response, defined as change from baseline in total z-score after 12 weeks of treatment. The NTB Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean at baseline. Negative numbers indicate values lower than baseline and positive numbers indicate values higher than baseline. Change from baseline will be calculated as the post-baseline composite z-score minus the pre-treatment z-score, such that a positive change indicates an improvement from baseline

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing BI 409306 in people with Alzheimer Disease, run by Boehringer Ingelheim at 52 sites in 12 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 52 sites in Poland, United States, Canada, Germany, Spain and 7 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment. (time frame: Baseline and 12 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02240693, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2018.
