A treatment-emergent adverse events (TEAE) was defined as AEs with an onset date on or after the date of first dose and within 28 days after the date of the last dose.
Any AE that occurred beyond this timeframe and was assessed by the investigator as possibly related to study drug was considered treatment-emergent.
The intensity and severity of AEs was assessed by the investigator according to the Common Terminology Criteria for Adverse Event (CTCAE) Version 4.0.
For any AEs not listed in the CTCAE grading system, the intensities of these events was assessed by the Investigator using the 5-point scale: Grade 1 = Mild, Grade 2 = Moderate; Grade 3 = Severe, Grade 4 = Life threatening, Grade 5 = Death.
An SAE is any AE occurring that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, and constitutes an important medical event.
