Ertugliflozin in Chronic Heart Failure

This study is looking at how two medications, ertugliflozin and metolazone, compare to a placebo (an inactive substance) in people with chronic heart failure. Researchers want to see how these treatments affect heart failure symptoms when added to your usual diuretic (water pill) therapy. You could be eligible if you have chronic heart failure, take a daily oral loop diuretic, have an eGFR (a measure of kidney function) of 20 mL/min/1.73 m2 or higher, and speak English. The study will measure changes in your body's fluid levels to understand how well these treatments work. The study is currently unclear on its recruitment status.

Study design
This is a randomized, placebo-controlled study involving about 60 participants. You would be randomly assigned to receive ertugliflozin, metolazone, or a placebo.
What's involved
You would receive treatment for six weeks. Researchers will measure changes in your plasma volume at 7 days and 6 weeks, and your natriuretic effect (how much salt your body gets rid of) at 1 day.
Compensation
Not stated in the trial record.
Follow-up
The study measures outcomes up to 6 weeks after starting treatment.

  • Change from baseline to day 7 of plasma volume by add-on to loop diuretic therapy7 days

    The primary outcome of the chronic effects of add-on placebo, thiazide-like diuretic, or SGLT2 inhibitor is to determine the change in plasma volume from baseline to day 7

  • Change from baseline to 6 weeks of plasma volume by add-on to loop diuretic therapy6 weeks

    The primary outcome of the chronic effects of add-on placebo, thiazide-like diuretic, or SGLT2 inhibitor is to determine the change in plasma volume from baseline to 6 weeks

  • Natriuretic effect of adjuvant to loop diuretic therapy1 day

    The natriuretic effect of each arm with loop diuretic therapy will be measured by the urine sodium output and FeNa.
