Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the PD of DSP-2230 using the GFR measured by iohexol plasma clearance. The primary PD endpoint is the glomerular filtration rate (GFR) measured by iohexol clearance on days -1 (baseline) and on day 1 (after a single dose of DSP2230 or placebo) and day 13 (after multiple dosing of DSP-2230 or placebo). | — |
Secondary
| Measure | Time frame |
|---|---|
| Pharmacodynamic endpoints: The secondary PD endpoints comprise the following: 1. Renal plasma flow measured by para-amino hippurate (PAH) clearance 2. Urinary and plasma creatinine levels 3. Symmetrical dimethyl arginine (SDMA) 4. Cystatin-C Pharmacokinetic endpoints: The plasma concentration time profile and PK parameters of DSP-2230 will be determined from plasma samples collected on Day 1 (single dose) and Day 14 (multiple doses). Safety endpoints: Safety and tolerability will be assessed using the following endpoints: 1. Adverse events (AEs) and serious AEs (SAEs) 2. Vital signs 3. Electrocardiogram (ECG) and ECG time intervals 4. Clinical chemistry and haematology 5. Urinalysis including biomarkers of renal function The secondary PD endpoint is the renal plasma flow measured by PAH clearance and the tubular secretion of creatinine on days -1 (baseline) and on day 1 (after a single dose of DSP-2230 or placebo) and day 13 (after multiple dosing of DSP-2230 or placebo). In addition, safety endpoints AEs, vital signs, ECG and ECG time intervals, clinical chemistry including serum creatinine, haematology and urinalysis including biomarkers of renal function, will be measured after single and 13 days multiple dosing of DSP-2230 or placebo. | — |
