Outcome Measures
Primary Outcome Measures
- Parts A, B and C: Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [Part A: Up to 54 days; Part B: Up to 53 days; Part C: Up to 71 days (SAD); Up to 85 days (MAD)]
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death; in the view of the investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect or is a medically important event.
- Parts A, B and C: Number of Participants With Clinically Significant Change From Baseline in Clinical Laboratory Parameters, Vital Signs, and 12-Lead Electrocardiogram (ECG) [Part A: Baseline up to 54 days; Part B: Baseline up to 53 days; Part C: Baseline up to 71 days (SAD), Baseline up to 85 days (MAD)]
- Parts A, B and C: Number of Participants With Change in Columbia Suicide Severity Rating Scale (C-SSRS) Score [Part A: Up to 54 days; Part B: Up to 53 days; Part C: Up to 71 days (SAD); Up to 85 days (MAD)]
C-SSRS is used to assess the suicidality of participants during the study. The assessment includes "yes" or "no" responses for 5 questions each, related to suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings are provided for severity of ideation, from 1 to 5, with 5 being the most severe.
- Part C: Percent O-GlcNAcase-Positron Emission Tomography (OGA PET) Target Engagement/Occupancy (TO) as a Function of Dose and Time [Up to Day 4 (SAD); Up to Day 17 (MAD)]
Secondary Outcome Measures
- Parts A and B: Area Under the Concentration-Time Curve From Time Zero to Time of the Last Measurable Concentration (AUClast) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Area Under the Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC∞) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Area Under the Plasma Concentration-Time Curve Within a Dosing Interval (AUCtau) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Maximum Observed Concentration (Cmax) for BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Trough Concentration (Ctrough) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Time to Maximum Observed Concentration (Tmax) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Terminal Elimination Half-Life (t½) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
t1/2 is the time measured for the plasma concentration to decrease by one half. The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Apparent Total Body Clearance (CL/F) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. If the bioavailability (F) of a dose is assumed to be 100% or equivalently, that clearance is the apparent clearance (CL/F) when the ratio of clearance to bioavailability is assumed to be constant. The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Apparent Volume of Distribution During the Terminal Elimination Phase (Vz/F) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
Volume of distribution is defined as the apparent volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed. The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Accumulation Ratio (AR) of BIIB113 [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Amount of BIIB113 Excreted in Urine (Aeu) [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
- Parts A and B: Percentage of BIIB113 Excreted in Urine (%fe) [Part A: Pre-dose and at multiple timepoints post-dose on Days 1 to 4; Part B: Pre-dose and at multiple timepoints post-dose on Days 1 to 15]
The parameter will be assessed under fed conditions for Part A Cohort 3.
