Results from Part A of the Hemoglobin Oxygen Affinity Modulation to Inhibit HbS Polymerization (HOPE) Trial (GBT440-031), a Placebo-Controlled Randomized Study Evaluating Voxelotor (GBT440) in Adults and Adolescents with Sickle Cell Disease
Conclusions: Data from Part A of the HOPE study demonstrate that treatment with voxelotor resulted in a dose-dependent increase in Hb with a large proportion of patients achieving Hb >1 g/dL improvement from baseline compared with placebo at 12 weeks. In addition, there was a dose-dependent decrease in hemolysis markers. Voxelotor was generally well tolerated at both doses. Hemolytic anemia of SCD has severe and life-threatening consequences and presents an unmet medical need. Voxelotor has potential to ameliorate complications of anemia associated with SCD.DisclosuresVichinsky: bluebird bio: Membership on an entity's Board of Directors or advisory committees; Protagonist: Research Funding; Global Blood Therapeutics: Consultancy, Honoraria, Membership on an entity's Board of Directors or advisory committees, Research Funding.
