Male subjects (including those who have had a vasectomy) who engage in activity in which conception is possible must use barrier contraception (male latex condom or non-latex condom NOT made out of natural [animal] membrane [for example, polyurethane]) while receiving the IMP and for at least 28 days after taking the last dose of IMP Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 50 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 1
