Design outcomes

Primary

MeasureTime frameDescription
Incidence and severity of adverse events that are related to treatment with DonidalorsenUp to 176 daysThe safety and tolerability of multiple doses of Donidalorsen will be assessed by determining the incidence, severity, and dose relationship of adverse events that are related to treatment with Donidalorsen.
Peak plasma Concentration (Cmax) of DonidalorsenUp to 176 daysMaximum Donidalorsen plasma concentration, Cmax (ug/mL) will be assessed following SC administration
Time to peak plasma Concentration (Tmax) of DonidalorsenUp to 176 daysTime to peak Donidalorsen plasma concentration, Tmax (hours) will be assessed following SC administration
Effects of Donidalorsen on plasma PKK concentrationUp to 176 daysEffects of Donidalorsen on plasma PKK concentration after multiple doses of Donidalorsen compared to baseline
