Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change From Baseline in Negative Emotional Bias in the Facial Expression Recognition Task (FERT) | Days 7 and 14 of each Treatment Period (Two 14-day periods) | Faces with six different basic emotions (happiness, fear, anger, disgust, sadness, surprise) are briefly displayed on a screen and participants are required to indicate the expression of the face via a button-press. Cohort A only. |
| Primary | Change From Baseline in Cognitive Fluctuations | Screening, Days 1 and 14 of each Treatment Period (Two 14-day periods) | Dementia Cognitive Fluctuation Scale (DCFS). Number of participants with improvement relative to screening. Cohort B only. |
| Secondary | Change From Baseline in CANTAB Cognitive Assessments | Days 1, 7, 14 of each Treatment Period (Two 14-day periods) | The CANTAB cognitive assessments consists of a series of interrelated computerized tests of memory, attention, and executive function, administered via a touch sensitive screen. This includes the immediate and delayed Verbal Recognition Memory (VRM) recall and recognition tests that measure the ability to encode and subsequently retrieve verbal information. |
| Secondary | Digital Wearable Device (BioStamp) - Sleeping Heart Rate | Screening, Days 1-14 of each Treatment Period (Two 14-day periods) | A wireless device that measures physical activity and sleep while at home. |
| Secondary | Digital Wearable Device (BioStamp) - Sleeping Heart Rate Variability (HRV) | Screening, Days 1-14 of each Treatment Period (Two 14-day periods) | A wireless device that measures physical activity and sleep while at home. |
| Secondary | Digital Wearable Device (BioStamp) - Sleeping Heart Rate Variability (HRV) - Root Mean Square of Successive Differences (RMSSD) | Screening, Days 1-14 of each Treatment Period (Two 14-day periods) | A wireless device that measures physical activity and sleep while at home. |

|---|---|---|---|---|---|
| PRIMARY | Change From Baseline in Negative Emotional Bias in the Facial Expression Recognition Task (FERT) | Days 7 and 14 of each Treatment Period (Two 14-day periods) | Full Analysis Set (FAS) - The FAS included all randomized study subjects who had taken at least one dose of blinded study drug in this crossover study. In accordance with the protocol this outcome measure was only applicable for Cohort A.~Data are presented by treatment for each patient population analyzed. | Percent change | LEAST_SQUARES_MEAN |

| SECONDARY | Digital Wearable Device (BioStamp) - Sleeping Heart Rate | Screening, Days 1-14 of each Treatment Period (Two 14-day periods) | Per protocol, the BioStamp wearable device was used in a substudy that included only the clinical sites based in Australia and New Zealand. There were a total of 18 subjects in this substudy. However, only 9 subjects provided a dataset that could be analyzed for treatment effect (ie. that included baseline data and end of study period data). Data are presented by treatment for each patient population. | beats per minute | LEAST_SQUARES_MEAN |
