What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety of TD-0714 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 25) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics (PK) of TD-0714 in plasma after multiple doses - peak plasma concentration (Cmax) |  | Day 1 through Day 17 | 
| PK of TD-0714 in plasma after multiple doses - time to peak plasma concentration (Tmax) |  | Day 1 through Day 17 | 
| PK of TD-0714 in plasma after multiple doses - time to last measurable concentration (Tlast) |  | Day 1 through Day 17 | 
| PK of TD-0714 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 17 | 
| PK of TD-0714 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 17 | 
| PK of TD-0714 in plasma after multiple doses - CL/F (oral plasma clearance) |  | Day 1 through Day 17 | 
| PK of TD-0714 in plasma after multiple doses - Vz/F (apparent volume of distribution during the terminal phase) |  | Day 1 through Day 17 | 
| PK of TD-0714 in plasma after multiple doses - t1/2 (half-life) |  | Day 1 through Day 17 | 
| PK of TD-0714 in urine after multiple doses - Ae (amount excreted in urine) |  | Day 1 through Day 17 | 
| PK of TD-0714 in urine after multiple doses - Fe (fraction of oral dose excreted in urine) |  | Day 1 through Day 17 | 
| PK of TD-0714 in urine after multiple doses - Clr (renal clearance) |  | Day 1 through Day 17 | 
| Pharmacodynamic assessments for plasma atrial natriuretic peptide (ANP) concentrations |  | The day before dosing (Day -1) to 3 days after last dose (Day 17) | 
| Pharmacodynamic assessments for urine atrial natriuretic peptide (ANP) concentrations |  | The day before dosing (Day -1) to 3 days after last dose (Day 17) | 
| Pharmacodynamic assessments for plasma cyclic guanosine monophosphate (cGMP) concentrations |  | The day before dosing (Day -1) to 3 days after last dose (Day 17) | 
| Pharmacodynamic assessments for urine cyclic guanosine monophosphate (cGMP) concentrations |  | The day before dosing (Day -1) to 3 days after last dose (Day 17) |
