Study Endpoints

Primary Endpoints

Change from Baseline to Week 6 in the MADRS (Montgomery-Åsberg Depression Rating Scale) total score
Up to approximately Week 6

MADRS is a depression rating scale consisting of 10 items representing the core symptoms of depressive illness, each rated 0 (no symptom) to 6 (severe symptom). Total score ranges from 0 (no depression) to 60 (severely depressed).

Number of Participants with Adverse Events (AEs)
Up to approximately 10 weeks

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study

Change from Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score.
Up to approximately 6 weeks

Montgomery-Åsberg Depression Rating Scale (MADRS) The MADRS is a 10-item, clinician-rated scale that evaluates the participant's depressive symptomatology during the past week. Participants are to be rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. Each item will be scored on a 7-point scale with a score of 0 reflecting no symptoms and a score of 6 reflecting symptoms of maximum severity.

Number of Participants with Abnormal Change from Baseline in Vital Sign Measurements
Up to approximately 15 days

Number of participants with abnormal change from baseline in vital sign measurements like systolic and diastolic blood pressure will be assessed.

Change From Baseline in Electrocardiograms (ECGs)
Up to approximately 15 days

12-lead resting ECG will be recorded.

Number of Participants with Abnormal Change in Physical Examinations
Up to approximately 15 days

Number of participants with abnormal change in physical examinations in areas like cardiovascular, respiratory, gastrointestinal, and neurological systems will be assessed.

Number of Participants with Abnormal Change in Clinical Laboratory Test Results Like Hematology will be Assessed
Up to approximately 15 days

Number of participants with abnormal change in clinical laboratory test results like hematology will be assessed.

Maximum observed concentration (Cmax) of ABBV-1354
Up to approximately 15 days

Cmax of ABBV-1354 will be assessed.

Time to Cmax (peak time, Tmax) of ABBV-1354
Up to approximately 15 days

Max of ABBV-1354 will be assessed.

Terminal phase elimination half-life (t1/2) of ABBV-1354
Up to approximately 15 days

Terminal phase elimination half-life (t1/2) of ABBV-1354 will be assessed.

Area under the plasma concentration-time curve (AUC) from time 0 to the time of the last measurable concentration (AUCt) of ABBV-1354
Up to approximately 15 days

AUCt of ABBV-1354 will be assessed.

Area under the plasma concentration-time curve (AUC) from time 0 to infinite time (AUCinf) of ABBV-1354
Up to approximately 15 days

AUCinf of ABBV-1354 will be assessed.

Amount of ABBV-1354 excreted in the urine over the sampling period (Aeu)
Up to approximately 15 days

Amount of ABBV-1354 excreted in the urine over the sampling period (Aeu) will be assessed.

Percent of ABBV-1354 excreted in the urine
Up to approximately 15 days

Percent excreted = 100 × (Aeu/dose).

Amount of ABBV-1354 excreted in the feces over the sampling period (Aeu)
Up to approximately 15 days

Amount of ABBV-1354 excreted in the feces over the sampling period (Aeu) will be assessed.

Percent of ABBV-1354 radioactivity excreted in the feces
Up to approximately 15 days

Percent excreted = 100 × (Aeu/dose).

Secondary Endpoints

Change from Baseline to Week 6 in Clinician Global Impression of Severity - Bipolar Disorder (CGI-S-BP) score
Up to approximately Week 6
Change from Baseline in Clinical Global Impression (CGIS)
