Myelodysplastic Syndromes study: Elritercept
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 study aims to learn how safe elritercept is and how well adults with anemia from low‑risk MDS tolerate different doses. It also looks at the drug’s effect on anemia and the production of healthy red blood cells.
- Who it's for
- Adults who have anemia and very low, low, or intermediate‑risk myelodysplastic syndromes.
- What's involved
- Participants will receive elritercept at a dose assigned by the study and will have regular clinic visits and blood tests to check safety and anemia levels.
- 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.
