Primary
| Measure | Time frame |
|---|---|
| Safety of TD-1439 by assessing the number and severity of adverse events, including changes in vital signs, physical examination, laboratory safety tests, and ECGs | From Day 1 through end of study (Day 10) |
Secondary
| Measure | Time frame |
|---|---|
| PK of TD-1439 in plasma after multiple doses - time to peak plasma concentration (Tmax) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - time to last measurable concentration (Tlast) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - area under the plasma concentration vs. time curve from time zero to the last quantifiable concentration (AUC0-t) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - area under the plasma concentration vs. time curve from time zero to 24 hours postdose (AUC0-24) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - CL/F (oral plasma clearance) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - Vz/F (apparent volume of distribution during the terminal phase) | Day 1 through Day 10 |
| PK of TD-1439 in plasma after multiple doses - t1/2 (half-life) | Day 1 through Day 10 |
| Pharmacokinetics (PK) of TD-1439 in plasma after multiple doses - peak plasma concentration (Cmax) | Day 1 through Day 10 |
| PK of TD-1439 in urine after multiple doses - Fe (fraction of oral dose excreted in urine) | Day 1 through Day 10 |
| PK of TD-1439 in urine after multiple doses - Clr (renal clearance) | Day 1 through Day 10 |
| Pharmacodynamic assessments for plasma atrial natriuretic peptide (ANP) concentrations | The day before dosing (Day -1) to 3 days after last dose (Day 4) |
| Pharmacodynamic assessments for urine atrial natriuretic peptide (ANP) concentrations | The day before dosing (Day -1) to 3 days after last dose (Day 4) |
| Pharmacodynamic assessments for plasma cyclic guanosine monophosphate (cGMP) concentrations | The day before dosing (Day -1) to 3 days after last dose (Day 4) |
| Pharmacodynamic assessments for urine cyclic guanosine monophosphate (cGMP) concentrations | The day before dosing (Day -1) to 3 days after last dose (Day 4) |
| PK of TD-1439 in urine after multiple doses - Ae (amount excreted in urine) | Day 1 through Day 10 |
