DLTs were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.0 (NCI CTCAE v4.0). Percentages have been rounded off to the first decimal point. | Day 1 of Cycle 1 to Day 1 of Cycle 2 (1 cycle = 28 days) in dose-escalation phase | |
| Primary | Percentage of Participants With Adverse Events (AEs) | An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. Percentages have been rounded off to the first decimal point. | From study start up to end of study (Up to a maximum of 69 months) | |
