- Abstract
Aim: Single-arm, open-label, phase 3 study to evaluate the efficacy and safety of ferric derisomaltose (FDI) for iron deficiency anemia (IDA) in Japanese women with postpartum hemorrhage (PPH)., Methods: Postpartum women aged 20-39 years with serum ferritin <25.0 ng/ml, hemoglobin (Hb) <10.0 g/dl, and blood loss ≥500 ml within 24 h post-delivery were eligible to receive high-dose intravenous FDI. The primary endpoint was the maximum change in Hb concentration by Week 8. Key secondary endpoints included change in iron parameters and percentage of patients with a total Edinburgh Postnatal Depression Score (EPDS) ≥9. Safety assessments included treatment-emergent adverse events (TEAEs) and iron concentrations in maternal milk., Results: All (n = 21 [100.0%]) patients received the predetermined total iron dose by Day 8. Hb concentrations increased rapidly and significantly (p < 0.001) following FDI. Serum ferritin levels also increased rapidly and were maintained near or above the upper limit of normal reference value (250 ng/ml). Following FDI, two (9.5%) patients had a total EPDS score of ≥9. TEAEs occurred in 23 of 42 (54.8%) patients and neonates overall, including 18 of 21 (85.7%) patients and 5 of 21 (23.8%) neonates. TEAEs were mild in all adult patients and four neonates, and moderate in one neonate. Iron concentrations in maternal milk remained within normal reference values. Appropriate patient selection and patient-adjusted dosage selection facilitated safe and effective administration of high-dose (≥1000 mg) FDI., Conclusions: Rapid and sustained improvements in Hb and iron stores occurred following FDI for IDA with PPH, with no new safety signals identified., Clinical Trial Identifier: JapicCTI-194888., (© 2023 The Authors.
