Voxelotor, sold under the brand name Oxbryta, is a medication used to treat sickle cell disease.[1] Evidence shows that it improves hemoglobin levels; however, overall benefits are unclear as of 2021.[1] It is taken by mouth.[1]

Common side effects include headache, abdominal pain, rash, fever, and tiredness.[1] Severe side effects may include allergic reactions.[1] Use in pregnancy is of unclear safety.[2] It is believed to work by improving the ability of abnormal hemoglobin to carry oxygen.[3]

Voxelotor was approved for medical use in the United States in 2019.[1] In Europe it was granted orphan designation in 2016.[3] In the United States it costs about 10,100 USD per month as of 2021.[4]

History

Voxelotor was granted accelerated approval by the U.S. Food and Drug Administration (FDA) in 2019,[7] and further clinical trials are required to verify and describe its clinical benefit.[6][8] The FDA granted the application for voxelotor fast track designation and orphan drug designation.[6][9] FDA considers it to be a first-in-class medication.[10] The approval of voxelotor was based on the results of a clinical trial with 274 participants with sickle cell disease.[6] The FDA granted the approval to Global Blood Therapeutics.[6][7]

In Europe it was granted orphan designation in 2016.[3] Developed by Global Blood Therapeutics, voxelotor is the first hemoglobin oxygen-affinity modulator.[11]
