Number of Participants Experiencing Adverse Events (AEs) On Study

An adverse event was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the treatment, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the treatment, was also considered an adverse experience.

Time frame: From the time of the run-in period prior to the first dose of study drug through the end of the poststudy period (up to 3 weeks)

Population: All Participants as Treated (APaT) Population; All participants who received at least one dose of the investigational drug.
