SU-DHL-8 non-Hodgkin lymphoma xenograft in SCID mice (in vivo proof of concept)
“A xenograft model with a Non-Hodgkin Lymphoma (NHL) cell line in severe combined immunodeficient (SCID) mice (SU DHL-8 tumours; study IMP23018) was used to provide in vivo POC for isatuximab.”
Human CD38-expressing tumour xenograft in SCID mice considered the most relevant efficacy model
“From the pharmacokinetic point of view, the SCID mice with a xenograft consisting of cells from a CD38 expressing cancer cell line was the most relevant species for non-clinical efficacy testing.”
EMA: xenograft gives evidence of anti-CD38 anti-tumour effect despite limitations (NHL not MM line, not systemic, lacks T/B cells)
“Notwithstanding the limitations of the model: whether the use of an NHL cell line is representative for the proposed indication (MM), the model not fully simulating a systemic tumour, the extent of mediated cytotoxicity as this model lacks T and B cells, this study provides evidence for the anti-tumour effect of isatuximab towards CD38.”
