Description
Summary
This clinical trial is a Phase 2 study that will evaluate the safety and clinical activity of etavopivat in patients with thalassemia or sickle cell disease and test how well etavopivat works to lower the number of red blood cell transfusions required and increase hemoglobin.
Official Title
A Phase 2 Open-Label Study to Evaluate Safety and Clinical Activity of Etavopivat in Patients With Thalassemia or Sickle Cell Disease
Details
Etavopivat is a potent, selective, orally bioavailable, small-molecule activator of pyruvate kinase red blood cell (PKR) being developed by Forma Therapeutics, Inc and is intended for use as a treatment for patients with sickle cell disease (SCD) or other inherited hemoglobinopathies or refractory anemias. This study is a multicenter, Phase 2, open-label, multiple-cohort study examining the safety and efficacy of etavopivat for the treatment of patients, age 12 to 65 years, with SCD or thalassemia. Three treatment cohorts based on the patients hemoglobinopathy (SCD or thalassemia) and transfusion requirements will be evaluated.

Eligibility
You can join if…
Open to people ages 12-65
- Provision of consent
- Female patients of childbearing potential must use acceptable methods of contraception, male patients are willing to use barrier methods of contraception
Cohort A (Sickle Cell Disease Transfusion Cohort)
- Confirmed diagnosis of sickle cell disease
- Chronically red blood cell transfused (sample or exchange [manual or via electrophoresis]) for primary stroke prevention or due to previous stroke. Chronic red blood cell transfusion is defined as: ≥ 6 red blood cell units in the previous 24 weeks before the first dose of study treatment and no transfusion-free period for > 35 days during that period
- At least 24 months of chronic monthly red blood cell transfusions for secondary stroke prevention/treatment of primary stroke (initial completed overt clinical stroke with documented infarction on brain computed tomography [CT] or magnetic resonance imaging [MRI])
- Prior to screening OR at least 12 months of chronic RBC transfusions for primary stroke prevention (abnormal TCD) prior to screening
- Documented adequate monthly transfusions with average HbS ≤ 45% (the upper limit of the established academic community standard) for the previous 12 weeks of red blood cell transfusions before the first dose of study treatment
Cohort B (Thalassemia Transfusion Cohort)
- Documented diagnosis of β-thalassemia, Hemoglobin E/ β-thalassemia or Hemoglobin H (α-thalassemia), or other thalassemia variant
- Chronically transfused, defined as: ≥ 6 red blood cell units in the previous 24 weeks before the first dose of study treatment and no transfusion-free period for > 35 days during that period
Cohort C (Thalassemia Non-transfused Cohort)
- Documented diagnosis of β-thalassemia, Hemoglobin E/ β-thalassemia or Hemoglobin H (α-thalassemia), or other thalassemia variant
- Hemoglobin ≤ 10 g/dL
