Depleted Donor Stem Cell Transplant in Children and Adults With Fanconi Anemia After Being Conditioned With a Regimen Containing Briquilimab

Sponsor: Porteus, Matthew, MD

View on ClinicalTrials.gov

Summary

The objective of this clinical trial is to develop a cell therapy for Fanconi Anemia which enables enhanced donor hematopoietic and immune reconstitution with decreased toxicity by transplanting depleted stem cells from a donor with and without using an experimental antibody treatment called JSP-191 as a part of conditioning. This experimental treatment will hopefully cause fewer side effects than chemotherapy (the current standard of care method). Participants will be administered the conditioning regimen, are assessed until they receive the depleted stem cell infusion, and will be followed for up to 2 years after the cell infusion.

Official title: TCRαβ+ T-cell/CD19+ B-cell Depleted Hematopoietic Grafts and a Reduced Intensity Preparative Conditioning Regimen Containing JSP191 (Briquilimab) to Achieve Engraftment and Blood Reconstitution in Patients With Fanconi Anemia
