Elrexfio: animal efficacy model or human cells?
elranatamab · BCMA x CD3
Efficacy evidence
Multiple myeloma xenograft models (MM.1S, OPM2, MOLP8) with varying BCMA expression
“The anti-tumor activity of elranatamab was evaluated in MM xenograft models (with MM.1S, OPM2, and MOLP8 cell lines) that had varying levels of BCMA expression.”
Why that model
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
EMA: in vivo xenograft studies provide sufficient proof-of-concept for use in multiple myeloma
“These in vivo studies provide sufficient proof-of-concept for the use of elranatamab in treatment of Multiple Myeloma.”
