Leqvio: how long were the pivotal tox studies?

inclisiran · PCSK9 (siRNA)
Longest pivotal study
40 weeks
“Inclisiran was also well-tolerated in repeat dose studies up to 29-weeks of duration in rats and 40-weeks of duration in monkeys.”

Pivotal GLP studies
Rat 29-week and monkey 40-week SC Q4W (13-week recovery); plus 4- and 15-week studies and 13-week monkey statin combination
“Toxicological characterization of inclisiran was performed in studies of 29 weeks in rats and 40 weeks in NHPs at doses up to 8 times (≤ 250 mg/kg Q4W) and 19 times (300 mg/kg Q4W) the MRHD (based on BSA), respectively.”

Route in tox
Subcutaneous, weekly to every 4 weeks (more frequent than clinical Q6M)
“It is important to note that animals were dosed more frequently in toxicology studies (QD to Q4W) than in clinical studies (Q3M or Q6M).”
