- Incidence and severity of adverse events that are related to treatment with IONIS TMPRSS6-Lrx [ Time Frame: Up to 148 Days ]The safety and tolerability of single and multiple doses of IONIS TMPRSS6-Lrx will be assessed by determining the incidence, severity, and dose relationship of adverse events that are related to treatment with IONIS TMPRSS6-Lrx
- Pharmacokinetics after single and multiple doses of IONIS TMPRSS6-Lrx (maximum observed drug concentration or Cmax) [ Time Frame: Up to 148 Days ]The plasma pharmacokinetics (maximum observed drug concentration or Cmax) of Ionis TMPRSS6-Lrx will be assessed following single and multiple dose SC administration
- Pharmacokinetics after single and multiple doses of IONIS TMPRSS6-Lrx (time taken to reach maximal concentration or Tmax) [ Time Frame: Up to 148 Days ]The plasma pharmacokinetics (time taken to reach maximal concentration or Tmax) of Ionis TMPRSS6-Lrx will be assessed following single and multiple dose SC administration
- Pharmacokinetics after single and multiple doses of IONIS TMPRSS6-Lrx (Plasma terminal elimination half-life (t1/2λz) [ Time Frame: Up to 148 Days ]The plasma pharmacokinetics (Plasma terminal elimination half-life (t1/2λz) of Ionis TMPRSS6-Lrx will be assessed following single and multiple dose SC administration
- Pharmacokinetics after single and multiple doses of IONIS TMPRSS6-Lrx (Partial areas under the plasma concentration-time curve from zero time (predose) to selected times (t) after the subcutaneous administration (AUCt) [ Time Frame: Up to 148 Days ]The plasma pharmacokinetics (Partial areas under the plasma concentration-time curve from zero time (predose) to selected times (t) after the subcutaneous administration (AUCt) of Ionis TMPRSS6-Lrx will be assessed following single and multiple dose SC administration
- Pharmacokinetics after single and multiple doses of IONIS TMPRSS6-Lrx (Percentage of the administered dose excreted in urine (% Dose Excreted) [ Time Frame: Up to 148 Days ]The plasma pharmacokinetics (Percentage of the administered dose excreted in urine (% Dose Excreted) of Ionis TMPRSS6-Lrx will be assessed following single and multiple dose SC administration
- Pharmacodynamics after single and multiple doses of IONIS TMPRSS6-Lrx (Changes in transferrin saturation) [ Time Frame: Up to 148 Days ]Effects of IONIS TMPRSS6-Lrx on changes (absolute and percent) in transferrin saturation compared to baseline
- Pharmacodynamics after single and multiple doses of IONIS TMPRSS6-Lrx (Changes in serum iron) [ Time Frame: Up to 148 Days ]Effects of IONIS TMPRSS6-Lrx on changes (absolute and percent) in serum iron compared to baseline
- Pharmacodynamics after single and multiple doses of IONIS TMPRSS6-Lrx (Changes in hepcidin levels) [ Time Frame: Up to 148 Days ]Effects of IONIS TMPRSS6-Lrx on changes (absolute and percent) in hepcidin levels compared to baseline
