An AE could be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of study treatment, was also an AE. The number of participants who experienced at least one AE was presented for the first course pembrolizumab treatment per protocol.","groups":[{"description":"Participants received pembrolizumab, 10 mg/kg, intravenously (IV) once every 2 weeks, and continued to receive study drug until disease progression, death, withdrawal of consent, Investigator decision, or end of study (up to 2 years).
