An AE is any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death, initial or prolonged inpatient hospitalization, life-threatening experience (immediate risk of dying), persistent or significant disability or incapacity, congenital anomaly. Treatment-emergent are AEs that are absent before treatment or that worsened relative to pretreatment state. Pre-defined AESI for this study are outlined in study protocol.

Clinically significant laboratory abnormalities are those that meet the Common Terminology Criteria for Adverse Events (CTCAE) definition.

Clinically significant vital sign abnormalities include pulse rate \<40, \>100 or \>120 bpm; systolic blood pressure increase from baseline ≥30 or decrease ≤30 mmHg; diastolic blood pressure increase from baseline ≥20 or decrease ≤20 mmHg.

Clinically significant ECG abnormalities include mild (\>450-480 millisecond \[msec\]), moderate (\>480-500 msec or 30-60 msec increase from baseline), and severe (\>500 msec or \>60 msec increase from baseline) QTc prolongation.

FVC is the volume of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. DLCO is a measure of gas exchange diffusion capacity.

C-SSRS assesses whether participant experienced following: completed suicide (1), suicide attempt (2) (response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (3)("Yes" on "preparatory acts or behavior"), suicidal ideation (4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent), any suicidal behavior or ideation, self-injurious behavior (7)("Yes" on "Has subject engaged in non-suicidal self-injurious behavior").
