Emrelis: genotox, carcinogenicity and repro: done or skipped?

telisotuzumab vedotin · c-Met
Genotoxicity
Not conducted with ADC; MMAE aneugenic (positive rat micronucleus), Ames and mouse lymphoma negative
“Genetic toxicology studies were not conducted with telisotuzumab vedotin but were conducted with the MMAE payload.”
✓ VerifiedFDA multi-discipline review, p. 35Source ↗
Carcinogenicity
Not conducted (not warranted for advanced cancer)
“FDA agrees that carcinogenicity studies are not warranted to support this application.”
✓ VerifiedFDA multi-discipline review, p. 52Source ↗
Reproductive & developmental
Not conducted with ADC (ICH S9); MMAE rat EFD teratogenic; ovary/uterus and testis findings in repeat-dose
“Reproductive toxicology studies with telisotuzumab vedotin are not warranted to support this application because MMAE is genotoxic and affects actively dividing cells.”
✓ VerifiedFDA multi-discipline review, p. 52Source ↗
Safety pharmacology
Incorporated into GLP monkey repeat-dose studies (ECG, clinical signs); MMAE hERG IC50 >100 µM
“Stand-alone safety pharmacology studies were not conducted with telisotuzumab vedotin.”
✓ VerifiedFDA multi-discipline review, p. 40Source ↗
