General information about the trial
|
|||
Main objective of the trial |
The main purpose of this study was to evaluate bintrafusp alfa monotherapy in subjects with triple negative breast cancer (TNBC) who express high levels of HMGA2 as determined by a centralized reverse transcriptase-polymerase chain reaction (RT-PCR) test.
|
||
Protection of trial subjects |
Subject protection was ensured by following high medical and ethical standards in accordance with the principles laid down in the Declaration of Helsinki, and that are consistent with Good Clinical Practice and applicable regulations.

Number of Subjects With Treatment-Emergent Adverse Events (TEAEs), Treatment-Related AEs, and Adverse Events of Special Interest (AESIs) | ||||||||||||
End point description |
An AE was defined as any untoward medical occurrence in a subject administered a pharmaceutical product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether considered related to the medicinal product or protocol-specified procedure. Serious AE was defined AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial/prolonged inpatient hospitalization; congenital anomaly/birth defect. TEAE was defined as events with onset date or worsening during the on-treatment period. TEAEs included serious TEAEs and non-serious TEAEs. The AESIs considered in this study are infusion-related reactions including immediate hypersensitivity, immune-related adverse events, skin adverse events, bleeding events and anemia.
