New treatment option for Myelodysplastic Syndromes
Official title A Study of Elritercept to Treat Anemia in Adults With Very Low, Low, or Intermediate Risk Myelodysplastic Syndromes (MDS)
ClinicalTrials.gov ID: NCT04419649
What this study is testing
What is Elritercept?
Elritercept is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for myelodysplastic syndromes.
Also referred to as KER-050, TAK-226.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The main aim of this study is to learn how safe elritercept is and how well adults with anemia associated with lower-risk MDS tolerate treatment with different doses of elritercept. Other aims are to learn how safe elritercept is by looking at how many participants have MDS that worsens during the study and learn about the effects of elritercept on anemia linked to MDS.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
