Summary

This trial is testing a study drug (fostamatinib) in people who have cytopenia after a blood stem cell transplant to see if it helps keep blood cell levels stable.

Who is the study for?
Adults aged 18-75 with low blood cell counts after a stem cell transplant can join. They must use effective birth control, not have HIV/HBV/HCV, and be stable on current medications. Excluded are those with uncontrolled hypertension, recent biologic treatments, severe psychiatric issues, certain liver abnormalities, or other autoimmune causes of low blood cells.
What is being tested?
The trial is testing fostamatinib tablets taken twice daily for 12 weeks to treat cytopenia in post-stem cell transplant patients. Participants will undergo regular medical assessments including physical exams and various tests at NIH clinics or via telehealth.
What are the potential side effects?
Potential side effects of fostamatinib may include high blood pressure (hypertension), digestive disturbances like diarrhea or nausea, liver enzyme elevations indicating potential liver damage, and an increased risk of infections due to immune system effects.
