A Randomized, Open‐Label, Single‐Dose, Parallel‐Group Bioequivalence Study of Ferric Carboxymaltose Injection Under Fasting Conditions in Chinese Adult Subjects With Iron Deficiency Anemia

Year: 2025

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: ABSTRACT The objectives of this study were to compare the pharmacokinetics and safety profiles of the test (T) preparation (Ferric carboxymaltose injection, BrightGene Bio‐Medical Technology Co. Ltd.) and reference (R) preparation (Ferinject, Vifor France) after intravenous injection in Chinese adult subjects with iron deficiency anemia (IDA) under fasting conditions. Conducted as a single‐center, randomized, open‐label, parallel‐group trial, the study enrolled 96 IDA patients who were randomly allocated (1:1) to receive a 500 mg intravenous dose of either the T or R preparation. Post‐dose blood samples for pharmacokinetic analysis were collected at multiple time points, while any adverse events were documented. The pharmacokinetic results showed comparable serum concentration‐time curves between the two groups. The 90% confidence intervals for the geometric mean ratios of Cmax, AUC0−t, and AUC0−∞ of total serum iron and Cmax, AUC0−t of serum transferrin‐bound iron were within the predefined bioequivalence criterion of 80%–125%, indicating bioequivalence between the T and R preparations under fasting conditions. There were no significant differences in the safety profile between the two groups. This study confirmed the bioequivalence of the T and R preparations under fasting conditions, along with good safety.
