PIONEERING GENE THERAPY CLINICAL PROGRAMS “During the kids’ entire childhood they had multiple
infections – ‘you name it they had it’ – and were admitted to the hospital several times due to these infections. Since treatment, the kids are back in day care and have scraped their knees – but unlike their experience before gene therapy,
this has not resulted in infections. This therapy “saved their lives” and without it don’t know whether or not the kids would be alive at present. The therapy gave hope and hope that it will be available for other kids with severe LAD-I.”
— FATHER OF THREE CHILDREN WITH SEVERE LAD-I “Due to the high unmet need, there is significant interest within the FA community from both patients and health care providers for an alternative low-toxicity therapy to address and, more
specifically, prevent BMF. Overall, the investigational gene therapy – administered with a preventative intent and requiring no cytotoxic conditioning therapy – represents a compelling potential option for FA patients, even though this
approach requires a more protracted time interval (i.e., 1-3 years) for recognition of phenotypic, genetic, and hematologic correction, relative to allogeneic HSCT.” — PRINCIPAL INVESTIGATOR OF ROCKET’S FA PROGRAM
