Efficacy evidence

Tumour cell xenotransplants in mice: inhibition of tumour cell growth in vivo

“Panitumumab was also shown to inhibit cell growth in vitro and in vivo (xenotransplants in mice) in the same cell line.”

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: rationale for EGFR inhibition well established; specific EGFR binding and signalling inhibition shown

“The rationale for EGFR inhibition in metastatic colorectal cancer is well established. The applicant has shown that panitumumab specifically binds to epidermal growth factor receptors and inhibits signalling through this receptor.”
