The objective of this study is to assess the therapeutic efficacy of a hematopoietic cell-based gene therapy for patients with Fanconi anemia, subtype A (FA-A).
Hematopoietic stem cells from mobilized peripheral blood of patients with FA-A will be transduced ex vivo (outside the body) with a lentiviral vector carrying the FANCA gene. After transduction, the corrected stem cells will be infused intravenously back to the patient with the goal of preventing bone marrow failure.
|Condition or disease||Intervention/treatment||Phase|
|Fanconi Anemia Complementation Group A||Biological: RP-L102||Phase 2|
This is a pediatric open-label Phase II clinical trial to assess the efficacy of a hematopoietic gene therapy consisting of autologous CD34+ enriched cells transduced with a lentiviral vector carrying the FANCA gene in subjects with FA-A.
Enriched CD34+ hematopoietic stem cells will be transduced ex vivo with the therapeutic lentiviral vector and infused via intravenous infusion following transduction without any prior conditioning.

RP-L102 is CD34+ enriched cells from subjects with Fanconi anemia subtype A transduced ex vivo with a lentiviral vector carrying the FANCA gene

- Phenotypic correction of bone marrow colony forming units after infusion of RP-L102 [ Time Frame: 3 years ]During months 12-36 post-infusion, the survival of bone marrow colony forming units to 10nM mitomycin C (MMC) increases to over or equal to 10% with respect to values determined at baseline (pretreatment evaluation).
- Phenotypic correction of T-lymphocytes in peripheral blood after infusion of RP-L102 [ Time Frame: 3 years ]Assessment of the percentage of peripheral blood T-cells with diepoxybutane (DEB)-induced chromosomal aberrations
- Engraftment of gene-corrected hematopoietic cells after infusion of RP-L102 [ Time Frame: 3 years ]The level of gene marking of the FANCA-lentiviral vector (LV) provirus in total peripheral blood cells is at least 0.1 vector copy number (VCN) in peripheral blood cells during months 12-36 post-infusion
- Prevention or rescue of bone marrow failure after infusion of RP-L102 [ Time Frame: 3 years ]Assessment of the need for treatment of bone marrow failure 6-36 months post-infusion.
