What was measured

An AE was defined as any untoward medical occurrence in a participant administered a study treatment which did not necessarily have to have a causal relationship with this treatment. 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.

Analysis population: The population consisted of all participants who received ≥1 dose of study treatment.

Groups in this outcome

Cohort A: Triple Negative Breast Cancer

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). Participants who stopped study treatment without progression (e.g. completed 2 years) may have been eligible for up to 1 year of retreatment upon subsequently experiencing disease progression.

Cohort B: Head & Neck Cancer

Participants received pembrolizumab, 10 mg/kg, 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). Participants who stopped study treatment without progression (e.g. completed 2 years) may have been eligible for up to 1 year of retreatment upon subsequently experiencing disease progression.

Cohort C: Urothelial Cancer

Participants received pembrolizumab, 10 mg/kg, 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). Participants who stopped study treatment without progression (e.g. completed 2 years) may have been eligible for up to 1 year of retreatment upon subsequently experiencing disease progression.

Cohort D: Gastric Cancer

Participants received pembrolizumab, 10 mg/kg, 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). Participants who stopped study treatment without progression (e.g. completed 2 years) may have been eligible for up to 1 year of retreatment upon subsequently experiencing disease progression.

Cohort B2: Head & Neck Cancer Expansion

Participants received pembrolizumab, 200 mg, IV once every 3 weeks, and continued to receive study drug until disease progression, death, withdrawal of consent, Investigator decision, or end of study (up to 2 years). Participants who stopped study treatment without progression (e.g. completed 2 years) may have been eligible for up to 1 year of retreatment upon subsequently experiencing disease progression.
