Study Aim

This phase 2 study aims to evaluate the effectiveness of Tebapivat in treating anemia in individuals with lower-risk myelodysplastic syndromes, by observing the proportion of participants who experience an increase in hemoglobin levels and those who achieve transfusion independence.

Actual date on which the first participant was enrolled.

This study focuses on a treatment called tebapivat for individuals with lower-risk myelodysplastic syndromes (LR-MDS), a condition that causes anemia. The main goal is to prove that tebapivat works effectively in managing this condition in the first part of the study (Phase 2a), and then to evaluate its ability to help patients become less dependent on blood transfusions in the second part (Phase 2b). This research is important as it aims to provide a new treatment option that could potentially improve the quality of life for those living with LR-MDS. During the study, participants will receive tebapivat as part of their treatment. The effectiveness of this treatment will be measured in several ways. In Phase 2a, the study will look at the proportion of participants who show an improvement in their hemoglobin levels, a key indicator of anemia. It will also assess the number of participants who become transfusion-independent for at least 8 consecutive weeks. In Phase 2b, the primary focus will be on the proportion of participants who achieve transfusion independence for at least 8 weeks.
