Could a daily pill help kids with rare blood disorder?

NCT ID NCT05175105

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a drug called mitapivat in children aged 1 to 18 with pyruvate kinase deficiency, a rare genetic condition that causes red blood cells to break down too quickly, leading to anemia. The trial compares mitapivat to a placebo to see if it can raise hemoglobin levels without the need for regular blood transfusions. About 30 children will take part, and those who finish the initial 20-week study can continue on mitapivat for up to 5 more years.

What this could mean

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

Active substance

mitapivat

What this could lead to

If it works, this could provide a daily pill to control anemia in children with pyruvate kinase deficiency, reducing symptoms and improving quality of life.

What could go wrong

This is a small, early-phase trial with only 30 children. The drug may not improve hemoglobin levels significantly, and long-term safety is still being studied.
