1. Overview of the Number of Participants With at Least One Treatment-Emergent Adverse Event, Severity Determined According to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.0 (NCI-CTCAE v4.0)

   Treatment-emergent adverse events (TEAEs) were adverse events (AEs) that started or worsened in severity on or after the first administration of study drug, up to and including 28 days after the last dose. The investigator graded all AEs for severity per NCI-CTCAE v4.0; if not listed, the AE was assessed as follows: Grade 1 = mild; Grade 2 = moderate; Grade 3 = severe; Grade 4 = life-threatening/disabling; Grade 5 = death. The investigator determined whether an AE was related to study drug and independently assessed severity and seriousness of each AE. TEAEs to monitor included anaphylaxis and hypersensitivity, cardiac dysfunction, diarrhoea Grade ≥3, pregnancy-related AEs, interstitial lung disease, infusion-/administration-related reactions, mucositis, (febrile) neutropenia, rash/skin reactions, and suspected transmission of infectious agent. TEAEs of special interest included LVEF decreased, liver enzymes increased, and suspected transmission of infectious agent by the study drug.

   Measured: From Baseline until 28 days after, or 7 months after (only for serious AEs related to study drug), the last dose of study treatment. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.

2. Number of Participants Who Died Over the Course of the Study by Reported Cause of Death (Adverse Events Leading to Death by System Organ Class and Preferred Term)

   All adverse events leading to death, regardless of whether they were classified as treatment emergent, are listed by system organ class (SOC) and preferred term (PT) according to the Medical Dictionary for Regulatory Activities, version 22.1 (MedDRA version 22.1); PTs that are part of a given SOC are listed in the rows directly below each SOC within the results table. Admin. = administration; Mediast. = mediastinal

   Measured: The median (full range) duration of follow-up was 68.73 (0.03-87.29) months.

3. Number of Participants Who Died Within 6 Months of Starting Study Treatment by Reported Cause of Death (Adverse Events Leading to Death by System Organ Class and Preferred Term)

   All adverse events leading to death, regardless of whether they were classified as treatment emergent, are listed by system organ class (SOC) and preferred term (PT) according to the Medical Dictionary for Regulatory Activities, version 22.1 (MedDRA version 22.1); PTs that are part of a given SOC are listed in the rows directly below each SOC within the results table.

The investigator determined whether an AE was related to study drug and independently assessed severity and seriousness of each AE. MedDRA version 22.1 was used to code AEs by system organ class (SOC) and preferred term (PT); PTs that are part of a given SOC are listed in the rows directly below each SOC within the results table. If a participant experienced the same AE at more than one severity grade, only the most severe grade was presented.

   Measured: From Baseline until 28 days after, or 7 months after (only for serious AEs related to study drug), the last dose of study treatment. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.

Some laboratory parameters are bi-dimensional (i.e. can be graded in both the low and high direction). These parameters were split and presented in both directions. Baseline was defined as the last non-missing measurement taken prior to the first dose of study treatment (including unscheduled assessments). Values from all visits, including unscheduled visits, were included in the derivation of the worst post-baseline grade. Not every abnormal laboratory value qualified as an adverse event, only if it met any of the following criteria: was clinically significant (per investigator); was accompanied by clinical symptoms; resulted in a change in study treatment; or resulted in a medical intervention or a change in concomitant therapy.

    Measured: Predose at each treatment cycle (1 cycle is 3 weeks) from Baseline until 28 days after the last dose of study treatment. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.

Baseline was defined as the last non-missing measurement taken prior to the first dose of study treatment (including unscheduled assessments). Values from all visits, including unscheduled visits, were included in the derivation of the worst post-baseline grade. Not every abnormal laboratory value qualified as an adverse event, only if it met any of the following criteria: was clinically significant (per investigator); was accompanied by clinical symptoms; resulted in a change in study treatment; or resulted in a medical intervention or a change in concomitant therapy.

    Measured: Predose at each treatment cycle (1 cycle is 3 weeks) from Baseline until 28 days after the last dose of study treatment. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.
