Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent Change From Baseline in Body Weight at Week 12	The efficacy analyses were performed using the Final Analysis Set which is defined as all randomized subjects who received one dose of study drug and had at least 1 primary efficacy assessment after administration of study drug	Baseline and 12 weeks
Secondary	Percentage of Subjects With =10% Weight Gain at Week 12	Percentage of weight gain is analyzed based on the subject's assessment status (=10% vs <10%) at Week 12 using a logistic regression model including treatment group, diagnosis (schizophrenia/schizophreniform disorder vs bipolar I disorder), region (US vs non-US), and baseline BMI (<25 vs =25) as factors and baseline weight as covariate.	Baseline and 12 weeks
Secondary	Percentage of Subjects With =7% Weight Gain at Week 12		Baseline and 12 weeks
Secondary	Number of Participants Experiencing of Adverse Events (AEs)		Up to 16 weeks
Secondary	Change From Baseline in Waist Circumference at Week 12		Baseline and Week 12
Secondary	Change From Baseline in Clinical Global Impression-Severity (CGI-S) Score Within the ALKS 3831 Group at Week 12	Clinical Global Impression-Severity (CGI-S) Score is a 3-item, clinician-rated scale used to assess global illness severity, overall improvement from the start of treatment, and therapeutic response. It is a 7-point scale that requires the clinician to assess how mentally ill the patient is at a specific point in time. Based on the scale, patients are categorized as follows: "1: normal, not at all ill"; "2: borderline mentally ill"; "3: mildly ill"; "4: moderately ill"; "5: markedly ill"; "6: severely ill"; and "7: among the most extremely ill patients."
