Clinical Trial Summary

Open-label extension study of voxelotor for participants with Sickle Cell Disease who have participated in voxelotor clinical trials.


Clinical Trial Description

Open-label extension (OLE) study of voxelotor for participants with Sickle Cell Disease who have participated in voxelotor clinical trials. Up to approximately 600 participants with sickle cell disease (SCD), will be enrolled at approximately 70 clinical sites globally. All participants will receive voxelotor once daily, administered orally as tablets, dispersible tablets, or powder for oral suspension formulation. The objective of this OLE is to assess the safety of, and SCD-related complications of, long-term treatment with voxelotor, in participants who have completed treatment in a Global Blood Therapeutics (GBT)-sponsored voxelotor clinical study. ;
