All patients were able to stop red blood cell transfusions by 90 days post-treatment, and hemolysis markers trended toward normalization in 25 patients. Dr. Keel indicated no relevant conflicts of interest. Gene transfer achieved by transplantation of the patient's own stem cells that have been genetically-modified with a corrected gene offers a potential alternative curative therapy. “VAMP4 has no known association with the development of AML nor with processes such as cellular proliferation or genome stability,” Gregory said. This site is strictly a news and information website about the disease. Bluebird bio told investors it wants to allow insurers to pay for its LentiGlobin treatment for transfusion-dependent beta-thalassemia over a period of as many as five years. The idea behind sickle cell gene therapy is that a person would receive some sort of gene that would allow their red blood cells to function normally. Theoretically, this would allow the disease to be cured. This would take several steps. First, the affected person would have some of their own stem cells removed.
