The effect of ferric citrate on heart failure

JRCT ID: jRCTs041220137

Registered date:08/02/2023

Basic Information

• Recruitment status: Complete
• Health condition(s) or Problem(s) studied: Heart failure
• Date of first enrollment: 24/10/2023
• Target sample size: 162
• Study type: Interventional

Intervention(s)

Intervention group: ferric citrate 250mg 2 tablets orally every day for 16 weeks
Control group: No treatment. If hemoglobin is less than 10g/dL, oral iron supplementation other than ferric citrate. Iron supplementation will be stopped when hemoglobin levels reach 10.5g/L

Outcome(s)

• Primary Outcome: % predicted peak VO2 measured by cardiopulmonary exercise testing
• Secondary Outcome: KCCQ score, left ventricular ejection fraction, BNP, ferritin, transferrin saturation, Hb, MCV, MCH, MCHC, RDW, hepcidin, BUN, creatinine, proteinuria
