RESUMO
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.

OBJECTIVES: NS-87/CPX-351 is a dual-drug liposomal encapsulation of cytarabine and daunorubicin. NS-87/CPX-351 exerts antileukemic action by maintaining a synergistic molar ratio of cytarabine to daunorubicin of 5:1 within the liposome while in circulation. Patients with high-risk acute myeloid leukemia (AML), which includes therapy-related AML and AML with myelodysplasia-related changes (AML-MRC), have poorer outcomes than those with other AML. METHODOLOGY: This open-label phase 1/2 (P1/2) study was conducted in 47 Japanese patients aged 60-75 years with newly diagnosed high-risk AML to evaluate the pharmacokinetics, safety, and efficacy of NS-87/CPX-351. RESULTS: In the 6 patients enrolled in the P1 portion, no dose-limiting toxicities (DLTs) were reported, and 100 units/m2 during the induction cycle was found to be acceptable. Cytarabine and daunorubicin had a long half-life in the terminal phase (32.8 and 28.7 h, respectively). In the 35 patients enrolled in the P2 portion, composite complete remission (CRc; defined as complete remission [CR] or CR with incomplete hematologic recovery [CRi]) was achieved in 60.0% (90% CI: 44.7-74.0) of the patients. Adverse events due to NS-87/CPX-351 were well tolerated. OUTCOMES: NS-87/CPX-351 can be considered as a frontline treatment option for Japanese patients with high-risk AML.
