Intravenous iron for bleeding symptoms in iron-deficient people with inherited bleeding disorders

Official title: Impact of IV Iron on Bleeding Symptoms in Iron Deficient Patients With Inherited Bleeding Disorders: a Single-arm Prospective Observational Study

Run by University of Pittsburgh · NCT07083583 · Data updated 2026-11-12

This single-center study will try IV iron infusions to see if they reduce bleeding symptoms and improve quality of life for people over 15 with inherited bleeding disorders and low iron (ferritin <50 ng/mL).

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people over 15 with a diagnosed inherited bleeding disorder, ferritin under 50 ng/mL, not taking antiplatelet or anticoagulant drugs, willing to have blood drawn and to return for a 3-month follow-up after IV iron.

Probably not a fit

Patients with a history of thrombosis, platelet count below 100,000/μL, or those using antiplatelet or anticoagulant medications are excluded and are unlikely to gain benefit from this protocol.

What this trial studies

This is a prospective, single-arm, single-center observational protocol enrolling patients older than 15 with inherited bleeding disorders and ferritin <50 ng/mL who are receiving standard-of-care IV iron at the Hemophilia Center of Western Pennsylvania. Participants complete baseline bleeding assessments, platelet/hematology labs, and quality-of-life questionnaires, receive an IV iron replacement per routine care, and return about three months later for repeat bloodwork and surveys. The study tracks changes in bleeding frequency, laboratory markers including platelet function and ferritin/hemoglobin, and patient-reported outcomes. All interventions are standard clinical care and the design is intended to observe whether correcting iron deficiency correlates with changed platelet function or bleeding symptoms.

Why it matters

Potential benefit: If successful, IV iron replacement could reduce bleeding symptoms and improve quality of life in iron-deficient patients with inherited bleeding disorders.

How similar studies have gone: Preclinical mouse studies and limited human data in women with iron-deficiency anemia suggest iron affects platelet function, but using IV iron to alter bleeding in inherited bleeding disorders is relatively novel and under-studied.
