New drug may boost recovery in kids with rare bone marrow failure
NCT ID NCT06430788
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving emapalumab early can help children with newly diagnosed severe aplastic anemia recover their blood cell counts within 6 weeks. About 35 children will receive the drug before standard treatments. The goal is to see if this approach improves treatment planning and outcomes.
