Summary
Study start date: January 1, 1988
Actual date on which the first participant was enrolled.This protocol was developed in order to obtain bone marrow stem cells for ex vivo transduction with retroviruses containing the human glucocerebrosidase gene. We continue to enter a small number of patients to this protocol each year. Studies with the bone marrow hematopoietic progenitor cells have enabled us to identify the most effective retroviral construct currently available in order to carry out gene therapy trials in patients with Gaucher's disease. The data revealed that a comparatively simple retroviral construct containing human glucocerebrosidase cDNA driven by the MoLV promoter is highly effective. We have obtained approval and initiated a Phase I safety and gene marking investigation in patients with Type I Gaucher's Disease.

Criteria
Normal and patient volunteers. Individuals with platelet counts less than 40,000/ul, PT greater than 15 seconds, or PTT greater than 40 seconds will not undergo bone marrow aspiration. Individuals with hematologic disorders other than Gaucher Disease, Fabry Disease, or mild iron deficiency will not undergo bone marrow aspiration. HIV positive individuals will be excluded from participating.
