Zoledronic Acid Treatment in Patients With Congenital Dyserythropoietic Anemia
Sponsor: Institute of Hematology & Blood Diseases Hospital, China
Summary
Background: Congenital Dyserythropoietic Anemia (CDA) is a group of rare hereditary blood disorders characterized by ineffective erythropoiesis, leading to chronic anemia and organ damage. Current treatment options are very limited, mainly relying on regular blood transfusions, which can cause severe complications over time. Our laboratory research and animal models suggest that Zoledronic acid, a medication commonly used for bone health, may improve ineffective erythropoiesis. Purpose: The purpose of this exploratory study is to evaluate the efficacy and safety of Zoledronic acid in adult patients with CDA who do not have other effective treatment options. The primary goal is to see if this treatment can increase hemoglobin levels and reduce the need for blood transfusions. Study Design: This is a prospective, single-center, single-arm study. Participants will receive an initial intravenous dose (4 mg) of Zoledronic acid. After a 4-week observation period to ensure safety, participants will receive additional doses every 4 weeks for a total of 4 doses. Researchers will monitor hemoglobin levels, transfusion frequency, spleen size, and overall quality of life over a period of 12 to 24 weeks.

Interventions
zoledronic acid
Zoledronic acid will be administered at a dose of 4 mg via a standardized intravenous (IV) infusion lasting no less than 15 minutes. To ensure safety, the initial dose is followed by a 4-week rigorous observation period. If the treatment is well-tolerated without significant adverse events, subsequent doses will be given every 28 days for a total of 4 cycles. Patients will be closely monitored for serum calcium levels and renal function (eGFR) throughout the intervention period to mitigate potential risks associated with bisphosphonate therapy.
