Description
This research study is being done to see if the investigational product being studied is well-tolerated. We hope to understand the safety of the product, and to see if it improves the health of patients with sickle cell disease.

Sickle cell disease is an inherited disorder. Red blood cells become sickle shaped (shaped like a crescent) and rigid. This leads to a variety of serious complications throughout the body. It is possible to replace the abnormal red blood cells in sickle cell patients with normal red blood cells. This is done by a bone marrow transplant from a matched donor.

The investigational product to be tested in the present study is known by its code name BIVV003. BIVV003 is made from stem cells that will be collected from your own blood. Stem cells are the primitive cells that make all your blood cells. The stem cells contain the genetic code for making hemoglobin. A portion of that code decides which kind of hemoglobin is made: adult, which is the sickle hemoglobin in your case, or fetal (baby hemoglobin). Bioverativ Therapeutics Inc. has found a way to change this code to make more of the fetal hemoglobin and less of the sickle hemoglobin.
