Combination of 177Lu-lilotomab satetraxetan with rituximab synergistically improves in-vivo therapeutic efficacy in a rituximab-resistant non-Hodgkin lymphoma (NHL) mode
Conclusions: Combination of 177Lu-lilotomab satetraxetan and rituximab synergistically decreased tumor growth compared with either treatment alone and had an additive effect with respect to survival. A clinical phase 1b study for relapsed follicular lymphoma where 177Lu-lilotomab satetraxetan is given in combination with rituximab (the Archer-1 study) is currently underway to investigate the safety and preliminary efficacy of the combination of 177Lu-lilotomab satetraxetan and rituximab. The data for the current preclinical study suggests that 177Lu-lilotomab satetraxetan could potentially reverse rituximab resistance.
