Must have
Adequate organ function defined as: Left ventricular ejection fraction > 40% or shortening fraction ≥ 25%. Creatinine clearance (CrCl) or glomerular filtration rate (GFR) ≥ 50 ml/ min/1.73m2. Forced vital capacity (FVC) ≥ 50% of predicted value; or pulse oximetry ≥ 92% on room air if patient is unable to perform pulmonary function testing.

Alanine aminotransferase (ALT) or Aspartate aminotransferase (AST) ≤ 5 times the upper limit of normal for age. Females and males of childbearing potential must agree to practice 2 effective methods of contraception at the same time or agree to abstinence until after the last dose of chemotherapy has been administered
Does not have a suitable HLA-matched sibling donor (MSD) or volunteer 10/10 HLA-matched unrelated donor (MUD) available in the necessary time for progenitor cell donation.

Study Summary

This trial is for patients with Severe Aplastic Anemia who will receive a haploidentical transplantation (from a family member that is not fully matched). The primary objective is to assess the rate of engraftment at 30 days and overall survival (OS) and event free survival (EFS) at 1 year.

Who is the study for?
This trial is for patients under 21 with Severe Aplastic Anemia who have failed at least one immunosuppressive therapy, lack a fully matched donor, and have good organ function. Donors must be family members partially matching the patient (≥3 of 6 HLA types), willing to donate stem cells, and HIV negative. Pregnant or breastfeeding women can't participate.Check my eligibility
What is being tested?
The study tests haploidentical hematopoietic cell transplantation (HCT) in SAA patients using chemotherapy, radiation, transplanted cells from half-matched family donors, and additional white blood cell infusions. It aims to assess engraftment success at 30 days post-transplantation and survival rates after one year.See study design
What are the potential side effects?
Possible side effects include reactions to medication like Anti-Thymocyte Globulin or Cyclophosphamide such as fever or chills; organ inflammation due to G-CSF; low blood counts from Fludarabine; immune complications like graft-versus-host disease; infection risks due to weakened immunity.

Experimental Treatment
Group I: Haploidentical HCTExperimental Treatment9 Interventions
To assess the safety and efficacy of haploidentical donor transplantation for patients with severe aplastic anemia who lack an available HLA-matched donor. The goal of this study is to develop a novel, reduced-toxicity, post-transplant pharmacologic immunosuppression (GVHD prophylaxis)- free, highly tolerogenic haploidentical transplant regimen that is associated with few post- transplant complications or late toxicities and is available promptly to all patients, irrespective of matched donor availability. Cells for infusion are prepared using the CliniMACS System.
