Study Endpoints

Primary Endpoints

Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs) and serious adverse events (SAEs) Following single ascending doses (SAD)
Baseline up to Day 35

An adverse event (AE) was any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or other important medical events. An AE was considered as treatment emergent if the event started during the effective duration of treatment. All events that started on or after the first dosing day up to the last dose plus the lag time were considered as TEAEs.

Number of Participants with Clinically significant Laboratory Abnormalities Following SAD
Baseline up to Day 35

Number of participants with any laboratory test abnormalities meeting pre-defined criteria was reported in this outcome measure.

Number of Participants with Change from Baseline in Electrocardiogram (ECG) Findings Following SAD
Baseline up to Day 35

Twelve lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR interval, QT interval, corrected QT (QTc) intervals and QRS complex. Clinically significant findings were determined by the investigator.

Number of Participants with Clinically Significant Change from Baseline in Vital Signs Following SAD
Baseline up to Day 35

Vital signs included blood pressure, pulse rate, respiratory rate, oxygen saturation and oral temperature. Clinically significant findings were determined by the investigator.

Number of Participants with Clinically Significant Change from Baseline in Cardiac Telemetry Findings Following SAD
Day 1

Cardiac telemetry was collected in Part 1 SAD cohorts only. Number of participants with any cardiac telemetry abnormalities were reported in this outcome measure.

Number of Participants With Treatment Emergent Treatment-Related AEs and SAEs Following multiple ascending doses (MAD)
Baseline up to Day 50

An adverse event (AE) was any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or other important medical events. An AE was considered as treatment emergent if the event started during the effective duration of treatment. All events that started on or after the first dosing day up to the last dose plus the lag time were considered as TEAEs.

Number of Participants with Clinically significant Laboratory Abnormalities Following MAD
Baseline up to Day 50

Number of participants with any laboratory test abnormalities meeting pre-defined criteria was reported in this outcome measure.

Number of Participants with Change from Baseline in Electrocardiogram (ECG) Findings Following MAD
Baseline up to Day 50

Twelve lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR interval, QT interval, corrected QT (QTc) intervals and QRS complex. Clinically significant findings were determined by the investigator.

Number of Participants With Treatment Emergent Treatment-Related AEs and SAEs in participants with atopic dermatitis (AD)
Baseline up to Day 80

An adverse event (AE) was any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or other important medical events. An AE was considered as treatment emergent if the event started during the effective duration of treatment. All events that started on or after the first dosing day up to the last dose plus the lag time were considered as TEAEs.

Number of Participants with Clinically significant Laboratory Abnormalities in participants with AD
Baseline up to Day 80

Number of participants with any laboratory test abnormalities meeting pre-defined criteria was reported in this outcome measure.

Number of Participants with Clinically Significant Change from Baseline in Vital Signs in participants with AD
Baseline up to Day 78

Vital signs included blood pressure, pulse rate, respiratory rate, oxygen saturation and oral temperature. Clinically significant findings were determined by the investigator.
