What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Adverse Events (AEs)

    An adverse event (AE) was defined as any untoward medical occurrence in a participant who was administered a pharmaceutical product (including investigational drug) during the course of a clinical investigation. An AE could therefore be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease that was temporally associated with the use of the investigational product, regardless of whether it was considered to be related to the investigational product or not.

    Measured: Up to approximately 16 months

  2. Number of Participants With Clinically Significant Changes in Vital Signs

    Number of participants with clinically significant abnormalities in vital signs such as systolic and diastolic blood pressure, heart rate, body temperature were evaluated.

    Measured: Up to approximately 16 months

  3. Number of Participants With Clinically Significant Changes in Electrocardiogram (ECG) Findings

    Measured: Up to approximately 16 months

  4. Number of Participants With Clinically Significant Changes in Clinical Laboratory Results

    Number of participants with clinically significant abnormalities in clinical laboratory parameters such as serum chemistry, hematology, coagulation, viral serology, urinalysis were evaluated.

    Measured: Up to approximately 16 months

  5. Number of Participants With Injection Site Reactions (ISRs)

    Injection site reactions (ISRs) referred to any localized sign or symptom, including pain, erythema, swelling and pruritus and were graded as follows: Grade 1: mild, Grade 2: moderate; Grade 3: severe. Adverse events related to ISRs were reported.

    Measured: Up to approximately 16 months
