New hope for breast cancer patients with low platelets from T-DM1

NCT ID NCT07257809

First seen Jan 05, 2026 · Last updated Jun 23, 2026 · Updated 22 times

Summary

This study tests whether the drug Hetrombopag can safely raise platelet counts in breast cancer patients who developed low platelets (thrombocytopenia) after T-DM1 treatment. About 56 participants will take Hetrombopag tablets daily for two weeks per cycle. The goal is to see if this helps maintain platelet levels so patients can continue their cancer therapy without delays.

What this could mean

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

Active substance

Hetrombopag Olamine Tablets

What this could lead to

If it works, this could help breast cancer patients avoid delays or dose reductions in their T-DM1 therapy by preventing low platelet counts.

What could go wrong

This is a small, early-phase study with only 56 participants and no comparison group, so results may not apply broadly. The drug may not effectively raise platelets or could cause side effects.
