What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Time Frame: From first dose of study intervention (Day 1) to telephone Follow Up (28-35 days after lase dose of study intervention) (approximately up to 20 weeks)
An adverse event (AE) was any untoward medical occurrence in a patient or clinical study subject, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious AE (SAE) was defined as any untoward medical occurrence that, at any dose: resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect; or other serious situations such as important medical events. TEAEs were events between first dose of study drug and up to follow-up visit that were absent before treatment or that worsened after treatment. AEs presented below were TEAEs. The investigator was required to use clinical judgment to assess the potential relationship between investigational product and each AE, to define an treatment-related AE.
From first dose of study intervention (Day 1) to telephone Follow Up (28-35 days after lase dose of study intervention) (approximately up to 20 weeks)
Number of Participants With Clinical Laboratory Abnormalities (Without Regard to Baseline [BL] Abnormality)
Time Frame: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
Safety laboratory assessments included clinical chemistry, hematology, urinalysis, and other tests. Abnormality was determined at the investigator's discretion.
From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
Number of Participants With Change From BL in Vital Signs Data Meeting the Pre-defined Categorical Summarization Criteria
Time Frame: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
Abnormality in change from BL in vital signs included: standing diastolic blood pressure (BP) increase and decrease from BL of >=20mmHg, standing systolic BP increase and decrease from BL of >=30mmHg, supine diastolic BP increase and decrease from BL of >=20mmHg, supine systolic BP increase and decrease from BL of >=30mmHg.
From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
Number of Participants With Change From BL in Electrocardiogram (ECG) Data Meeting the Pre-defined Categorical Summarization Criteria
Time Frame: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
ECG assessments inlcuded PR, QT, QTcF intervals and QRS complex. ECG abnormalities in change from BL included: PR interval BL >200msec and max >=25% increase from BL, or BL <=200msec and max >=50% increase from BL, QRS interval percent change from BL >=50%, QTcF change from BL >=30 and <=60msec, or change from BL >60msec.
From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
Number of Participants With Clinically-significant Change From BL in Neurological Examination Findings
Time Frame: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
The neurological exam consisted of assessment of higher cortical function, the cranial nerves, motor function, deep tendon reflexes, sensory exam, and coordination and gait, to the extent needed to assess the participant for any potential changes in neurological status, as determined by the investigator (or designee).
From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)
