Libtayo: animal efficacy model or human cells?
cemiplimab · PD-1
Efficacy evidence
Syngeneic colorectal tumor xenografts in huPD-1 knock-in mice treated with cemiplimab
“The Applicant investigated the in vivo anti-tumor activity of REGN2810 in huPD-1 mice bearing syngeneic colorectal cancer xenografts”
Why that model
Cemiplimab does not bind mouse PD-1, so humanized PD-1 knock-in mice were required
“Since REGN2810 does not bind mouse PD-1, mice were genetically engineered to express a human/mouse PD-1 chimeric receptor (huPD-1 mice)”
Reviewer's view of the efficacy data
EMA: pharmacology, PK and toxicology studies adequate and acceptable
“In conclusion, the non-clinical studies (pharmacology, pharmacokinetics and toxicology), submitted for the marketing authorisation application for cemiplimab, were considered adequate and acceptable for the assessment of non-clinical aspects.”
