Study Summary

This trial is for people with severe aplastic anemia, myelodysplastic syndrome, or paroxysmal nocturnal hemoglobinuria who want to receive a stem cell transplant using peripheral blood stem cells from a family member.

Who is the study for?
This trial is for people aged 4-55 with severe aplastic anemia, myelodysplastic syndrome (MDS), or paroxysmal nocturnal hemoglobinuria (PNH) who haven't responded to standard treatments. They need a family member donor aged 4-75. Participants must understand the study and consent; minors will need guardian consent. Exclusions include certain heart, liver, kidney issues, active infections not responding to treatment, HIV positive individuals, pregnant women or those not using birth control.Check my eligibility
What is being tested?
The trial tests if peripheral blood stem cells from a relative plus chemotherapy can treat SAA, MDS and PNH effectively and safely. Patients undergo extensive testing before receiving chemo and radiation followed by the stem cell transplant in hospital for about a month with follow-up visits over five years.See study design
What are the potential side effects?
Potential side effects may include reactions to the stem cell infusion such as fever or pain, complications from chemotherapy like nausea or hair loss, increased risk of infections due to weakened immune system post-transplantation and possible organ inflammation.
