I think there are large gaps between test completion and full readout because Anavex is both conducting clinical trials and wide-ranging, groundbreaking scientific research.

Anavex is the first to seriously explore the Sigma 1 receptor and its effect on CNS disease at large. This is a much more ambitious undertaking than just going through one monoclonal antibody after another, like Edison searching for the best light bulb filament. It goes quicker if you take the time to get it right the first time. And the payoff, as Missling has suggested over the years, will be worth the wait.

Here is the list of outcomes that have to analyzed, some of which will require a lot of lab time before analysis.

Primary Outcome Measures :
ADAS-Cog (Alzheimer Disease Assessment Scale-Cognition) [ Time Frame: 48 weeks ]
Reduction in cognitive decline assessed from baseline over 48 weeks with ANAVEX2-73 compared to placebo using the Alzheimer Disease Assessment Scale-Cognition (ADAS-Cog)

ADCS-ADL (Activities of Daily Living) [ Time Frame: 48 weeks ]
Reduction in decline of the ability to perform daily activities assessed from baseline over 48 weeks with ANAVEX2-73 compared to placebo using the Activities of Daily Living Scale (ADCS-ADL)


Secondary Outcome Measures :
CDR-SB (Clinical Dementia Rating Scale Sum of Boxes) [ Time Frame: 48 weeks ]
Reduction in cognitive decline assessed from baseline over 48 weeks with ANAVEX2-73 compared with placebo using the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB)

Number of participants with treatment-related adverse events as assessed by CTCAE v4.03 [ Time Frame: 48 weeks ]
Assess the safety and tolerability of ANAVEX2-73 compared to placebo


Other Outcome Measures:
Number of participants with change of brain volume assessed by MRI [ Time Frame: 48 weeks ]
To evaluate the effect of ANAVEX2-73 on structural and Arterial Spin Labeling (ASL) MRI scan assessments characteristic for AD pathophysiology compared to placebo over a 48-week treatment duration

Blood assessment [ Time Frame: 48 weeks ]
Blood assessment from baseline and compared to placebo at +48 weeks: Abeta40, Abeta42, T-tau, NFL, YKL-40, BACE1 concentration

CSF assessment [ Time Frame: 48 weeks ]
Changes in CSF parameters (Abeta40, Abeta42, T-tau, P-tau, NFL, YKL-40, neurogranin, BACE1 concentration) characteristic for AD pathophysiology from baseline and compared to placebo at

+48 weekstreatment differences within subgroups will be performed


Number of participants with pre-specified genetic variants [ Time Frame: 48 weeks ]
AD relevant pre-specified genetic variants will be assessed. Statistical testing of treatment differences within subgroups will be performed

RSCAQ sleep score [ Time Frame: Weeks 0, 4, 12, 24, 36, and 48 ]
To evaluate whether ANAVEX2-73 improves sleep continuity as assessed on a serial basis (weeks 0, 4, 12, 24, 36, and 48) with a questionnaire that assess reported sleep continuity (RSCAQ)
