Constant tumor growth over time was observed in untreated mice ofthe control group, resulting in three mice that reached the endpoint at Day 18.The tumor growth of mice treated with 5.0 MBq and 10 MBq161Tb-PSMA-617 was delayed, and hence the first mousefrom these groups had to be euthanized at Day 30 and Day 42 respectively. Here, FOLH1 is linked to neoplasm.
