Design outcomes
Primary
| Measure | Time frame |
|---|---|
| mean difference in blood pressure rise between the treatment cycle with and the treatment cycle without salt restriction. | — |
Secondary
| Measure | Time frame |
|---|---|
| effects of salt restriction on rise in endothelin-1, proteinuria as marker for nephropathy and pharmacokinetics of sunitinib and regorafenib; if an effect on blood pressure is shown, further analyses of effects on renal transporter proteins will be performed to explain the mechanism of salt sensitivity. | — |
