A Study of Emapalumab for Pediatric Aplastic Anemia

This study is looking at whether a treatment called emapalumab can help children and young adults (ages 0-25) with severe aplastic anemia (sAA). Aplastic anemia is a rare condition where your body stops producing enough new blood cells. Emapalumab works by blocking a protein called interferon gamma (IFNγ). The study aims to see if using emapalumab early can improve how well standard treatments work. To join, you would need to have suspected newly diagnosed sAA with low blood counts (cytopenias) and a bone marrow that doesn't have enough blood-forming cells (hypocellular marrow). Researchers will measure the best response to treatment after 6 weeks. The study plans to enroll 35 participants, but its current status is unclear.

Eligibility criteria

Inclusion

Patients undergoing workup for suspected newly diagnosed sAA:
Patients with severe cytopenias and a hypocellular marrow concerning for sAA
Patients that meet the definition for suspected sAA (Camitta Criteria) as follows:
Patients that do not have evidence of leukemia or MDS
Patients \< 25 years of age at time of diagnosis
Able to tolerate emapalumab and IST (with standard institutional organ function criteria)

Exclusion

Uncontrolled infection at presentation.
Patients who have undergone previous treatment for sAA.
Patients with known inherited bone marrow failure
Patient who has completed a full workup for sAA including having results back from telomere testing, DEB and genetics (when applicable), as well as having an appropriate willing and available donor and would otherwise be admitted for HSCT within 2 weeks of enrolling on the trial
Patients with leukemia or MDS
Patient or parent or guardian unable to give informed consent or unable to comply with the treatment protocol including research tests.
  • Best Response6 weeks

    The primary objective of the study is to assess the efficacy of early upfront emapalumab on hematologic recovery within 6 weeks of starting therapy after a new diagnosis of Aplastic Anemia. Response will be determined by blood count.
