Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective is to investigate the change in erythropoietin (EPO) levels after 2 weeks of treatment with dapagliflozin in comparison to treatment with placebo;Secondary Objective: to evaluate the change in physical fitness as assessed by spiroergometry and lactate threshold • to evaluate the impact of hydrochlorothiazide (HCT) on EPO levels • to measure the change in reticulocyte concentration, hematocrit and red blood cells • to measure the change in hypoxia-inducible factor (HIF) regulated hepcidin concentrations • to measure the change in iron status • to measure the change in catecholamine and steroid hormone concentrations Other objective(s) • to monitor glucose control • to monitor the safety and tolerability of the treatments as determined by the occurrence of adverse events and changes in vital signs and laboratory parameters • to evaluate the change in blood EPO levels between baseline and end of treatment (EoT);Primary end point(s): Change in blood EPO levels between baseline and after 2 weeks of treatment;Timepoint(s) of evaluation of this end point: Change in blood EPO levels between baseline and after 2 weeks of treatment

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Change in physical fitness between baseline and EoT as assessed by spiroergometry (VO2max, heart rate and lactate threshold) • Change in reticulocyte concentration, hematocrit and red blood cells between baseline and after 2 and 4 weeks of treatment • Change in hepcidin between baseline and after 2 and 4 weeks of treatment • Change in iron status between baseline and after 2 and 4 weeks of treatment as measured by Fe, ferritin, transferrin • Change in catecholamine (adrenalin, noradrenalin, and metabolites metanephrine and normetanephrine) and steroid hormone concentrations between baseline and after 2 and 4 weeks of treatment ;Secondary end point(s): Change in physical fitness between baseline and EoT as assessed by spiroergometry (VO2max, heart rate and lactate threshold) • Change in reticulocyte concentration, hematocrit and red blood cells between baseline and after 2 and 4 weeks of treatment • Change in hepcidin between baseline and after 2 and 4 weeks of treatment • Change in iron status between baseline and after 2 and 4 weeks of treatment as measured by Fe, ferritin, transferrin • Change in catecholamine (adrenalin, noradrenalin, and metabolites metanephrine and normetanephrine) and steroid hormone concentrations between baseline and after 2 and 4 weeks of treatment Other variable(s) • Fasting blood glucose (FBC) and HbA1c • Parameters derived from Flash Glucose Monitoring between screening and baseline (V1 to V2) and between V3 and EoT (V3 to V4) • Adverse events, vital signs (pulse, blood pressure), safety laboratory parameters • Change in blood EPO levels between baseline and EoT
