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.

Aim To examine the relationship between preterm birth and socioeconomic factors, past history, cervical length, cervical interleukin-8, bacterial vaginosis, underlying diseases, use of medication, employment status, sex of the fetus and multiple pregnancy. Methods In a multicenter, prospective, observational study, 1810 Japanese women registering their future delivery were enrolled at 8+0 to 12+6 weeks of gestation. Data on cervical length and delivery were obtained from 1365 pregnant women. Multivariate logistic regression analysis was performed. Results Short cervical length, steroid use, multiple pregnancy and male fetus were risk factors for preterm birth before 34 weeks of gestation. Multiple pregnancy, low educational level, short cervical length and part-timer were risk factors for preterm birth before 37 weeks of gestation. Conclusion Multiple pregnancy and cervical shortening at 20-24 weeks of gestation was a stronger risk factor for preterm birth. Any pregnant woman being part-time employee or low educational level, having a male fetus and requiring steroid treatment should be watched for the development of preterm birth. [ABSTRACT FROM AUTHOR]
