Sickle Cell Disease Clinical Trial
Official title:
An Adaptive, Randomized, Placebo-controlled, Double-blind, Multi-center Study of Oral Etavopivat, a Pyruvate Kinase Activator in Patients With Sickle Cell Disease (HIBISCUS)
This clinical trial is a Phase 2/3 study that will evaluate the efficacy and safety of etavopivat and test how well etavopivat works compared to placebo to improve the amount of hemoglobin in the blood and to reduce the number of vaso-occlusive crises (times when the blood vessels become blocked and cause pain).
Etavopivat is designed to activate PKR and thereby modulate RBC metabolism by impacting two critical pathways in RBCs. The etavopivat clinical development program will investigate whether decreasing 2,3-DPG may help oxygen bind to hemoglobin (i.e. increasing oxygen affinity), and thereby increase ATP and impact RBC function. This study is a randomized, placebo-controlled, double-blind, multicenter Phase 2/3 study of patients age 12 to 65 years (inclusive), with sickle cell disease. There are two planned interim analyses in this study design. Initially, patients will be randomized at 1:1:1 to one of two dose levels of etavopivat or placebo. At the first interim analysis, one of the two etavopivat dose levels will be selected for the Phase 3 portion of the study, in which patients will be randomized at 1:1 to the selected etavopivat dose or placebo. Efficacy on hemoglobin will be evaluated at the second interim analysis, and then will be tested along with evaluation of efficacy on vaso-occlusive crises at the final analysis. Following completion of 52 weeks of double-blind treatment, patients may enter a 52-week etavopivat open-label extension period. ;
