NCT ID NCT07319845

First seen Jun 25, 2026 · Last updated Jul 17, 2026 · Updated 3 times

Summary

This study tests a drug called TAK-226 (Elritercept) in 27 Japanese adults with lower-risk myelodysplastic syndromes (MDS) who need regular blood transfusions. The goal is to see if the drug can help them go without transfusions for at least 8 weeks. Participants will receive injections every few weeks and be followed for up to 6 years to check for side effects and long-term benefits.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
TAK-226 (also called Elritercept or KER-050), given as a shot under the skin
What this could lead to
If it works, this could help people with lower-risk MDS need fewer blood transfusions, improving their quality of life.
What could go wrong
This is an early phase 2 study with only 27 people, so results may not apply to everyone. It is not yet known if TAK-226 is safe or effective long-term.
