Clinical Trial Summary

This is an open, Phase I / II clinical trial to evaluate the safety and efficacy of a hematopoietic gene therapy procedure with an orphan drug consisting of a lentiviral vector carrying the FANCA gene for patients with Fanconi Anemia of Subtype A .

CD34 + cells derived from bone marrow and / or mobilized peripheral blood (fresh and / or cryopreserved) from patients with Fanconi subtype A (FA-A), will be transduced ex vivo with a lentiviral vector carrying the gene FANCA (orphan drug) . After transduction the cells will be inoculated in patients in order to restore their hematopoiesis with genetically corrected stem cells.

Description:

The main objective of this open-label Phase I / II clinical trial is to evaluate the safety and therapeutic efficacy of a hematopoietic gene therapy procedure with an orphan drug consisting of a lentiviral vector carrying the FANCA gene for patients with Fanconi's Anemia Subtype A.

The drug to be administered to the patients consists of the cellular product resulting from the transduction of autologous CD34 + cells with the therapeutic lentiviral vector PGK-FANCA.Wpre *.

The dose of cells to infuse in the patients will be that obtained from the transduction process of between 3x10^5 and 4x10^6 CD34 + cells / kg of patient body weight.

The cells will be infused intravenously in a single dose, after complete the transduction process.

Follow-up period: 3 years after infusion of transduced cells. However, patients will be monitored outside the clinical trial over a 10-year period.

Follow-up of the grafted transduced cells will be performed on peripheral blood and bone marrow samples.

Eligibility

Inclusion Criteria:

• Patients diagnosed with Fanconi Anemia complementation group A (FA-A)
