The groups of patients in each treatment arm are as follows:
Treatment Arm I (Bispecific Antibodies (BsAb)):
is for children, adolescents and young people with relapsed/refractory B-NHL in first relapse (only one prior line of therapy) or subsequent relapse (more than one prior line of therapy), including those achieving insufficient response (partial response (PR), Stable disease (SD), or progressive disease (PD)) to ADC therapy with standard chemotherapy to progress to transplantation or those without available CAR T-cells.
Treatment arm II (Antibody-Drug Conjugates (ADC) with standard chemotherapy):
is for children, adolescents and young people with relapsed/refractory B-NHL in first relapse (only one prior line of therapy) or subsequent (more than one prior line of therapy) relapse, including those achieving insufficient response to BsAb therapy to progress to transplantation or those without available CAR T-cells.
Treatment arm III (Chimeric Antigen Receptor (CAR) T-cells):
is for children, adolescents and young people with relapsed/refractory B-NHL who have had insufficient response (PR, SD, PD) to prior therapy to progress to transplantation and have CAR T-cell product available.
