Vafseo has a well-studied safety profile1

Vafseo was studied in ~2000 patients on dialysis with anemia due to CKD1,2

Vafseo was similar to an ESA in time to first occurrence of MACE1,*

Noninferiority of Vafseo to darbepoetin alfa was established because the upper-bound of the 95% CI for the MACE hazard ratio was less than the prespecified, noninferiority margin of 1.25.1

* MACE was defined as all-cause mortality, nonfatal myocardial infarction, and nonfatal stroke.1
Darbepoetin alfa was the control used in both clinical trials, and therefore noninferiority to other ESAs cannot be concluded.1
  CI=confidence interval; CKD=chronic kidney disease; ESA=erythropoiesis-stimulating agent; MACE=major adverse cardiovascular event.

  • Permanent treatment discontinuations due to an adverse reaction1
    • 4.9% of patients treated with Vafseo
    • 1.1% of patients treated with darbepoetin alfa
  • Gastrointestinal symptoms (nausea, vomiting, and diarrhea) resulted in permanent treatment discontinuation in 1.8% of patients treated with Vafseo1

||Grouped terms1:

  • Hypertension includes hypertensive crisis, pre-eclampsia, and hypertensive encephalopathy
  • Headache includes occipital neuralgia
  • Fatigue includes asthenia, lethargy, and malaise
  • Vomiting includes hematemesis
  • Gastrointestinal erosion includes duodenal ulcers and perforation, gastrointestinal ulcers and perforation, esophageal ulcers and perforation, and unspecified site or hematemesis, gastrointestinal hemorrhage, helicobacter duodenitis and gastritis, melaena, and gastric hemorrhage
  • Dizziness includes labyrinthitis, vertigo, vestibular neuronitis, and presyncope
  • Dyspnea includes orthopnea and respiratory distress

AV=arteriovenous; CKD=chronic kidney disease; GI=gastrointestinal; PY=person years.

Vafseo clinical trials examined other safety outcomes including thrombotic vascular events1
