Amondys 45
casimersen · DMD exon 45 (PMO)Conducted; negative (Ames, CHO chromosomal aberration, mouse micronucleus)
Rytelo: genotox, carcinogenicity and repro: done or skipped?
imetelstat · Telomerase (oligo)
Genotoxicity
Conducted; negative (Ames, in vitro micronucleus, in vivo mouse micronucleus)
“In genetic toxicity studies, imetelstat was not mutagenic in the in vitro bacterial reverse mutation assay.”
Carcinogenicity
Not conducted pre-approval; mouse and rat carcinogenicity studies required as PMRs
“To address the carcinogenicity risk assessment of imetelstat, there will be separate Post Marketing Requirements (PMRs) for carcinogenicity assessments in the mouse and rat species.”
Reproductive & developmental
EFD in mice and rabbits: post-implantation loss/resorptions; no fertility or PPND studies
“Increased rates of post-implantation loss and early resorptions that resulted in a decreased number of viable fetuses and litter size per animal, and decreased uterine weight were observed at”
Safety pharmacology
Stand-alone telemetered monkey CV/CNS/respiratory study plus ECG in 9-month monkey study; no effects
“There were no test article-related changes observed in the cardiovascular, central nervous or respiratory systems.”
