About the Study

What is the Study Goal?  

This study is looking at an investigational medicine called Pociredir to see if it is safe and if it works as expected to help people with sickle cell disease.  

What are the Study Details?  

Eligible participants will take one pill by mouth daily for 12 weeks. The study duration is up to 4 months, including a follow-up visit with the doctor or study team about 4 weeks after completing treatment.

How does Pociredir work? 

Hemoglobin is the protein in red blood cells that helps them carry oxygen. There are different types of hemoglobin including fetal hemoglobin and adult hemoglobin.  

Adult hemoglobin is abnormal in people with sickle cell disease, which causes red blood cells to become sickle-shaped and break down easily. However, fetal hemoglobin does not cause sickling and is better at carrying oxygen in those with sickle cell disease.  

Making more fetal hemoglobin can improve symptoms and can make sickle cell disease less severe. Pociredir may help increase fetal hemoglobin levels made in red blood cells.
