Clinical Trial Summary

This is phase I/II protocol to evaluate the safety and efficacy of WAS gene transfer into hematopoietic stem/progenitor cells for the treatment of Wiskott Aldrich Syndrome.


Description:

Wiskott-Aldrich Syndrome (WAS) is an X-linked primary immunodeficiency caused by mutations in the WAS gene which encodes the WAS protein (WASP), a cytoskeletal regulator which is expressed exclusively in hematopoietic cells.

Secondary Reduced autoimmunity phenomena and eczema Reduction in laboratory markers (number and titer of antibody when available) and/or clinical manifestations of autoimmunity, as evaluated by organ-specific and systemic autoantibodies, imaging and clinical follow-up, compared to clinical history. Reduction in eczema as evaluated by clinical score 3 years
Secondary Improved quality of life Improved quality of life, measured after the first year of treatment by reduced hospitalization, reduced requirement of drugs, school attendance, social activities. 3 year
Secondary Multilineage engraftment of genetically corrected cells =0.04 VCN/cell on all the available peripheral blood and/or bone marrow cell subpopulations (BM subpopulations: GlyA+, CD15+, CD61+, CD3+, CD19+, CD56+; PB subpopulations: CD15+, CD19+, CD56+) 3 years
