Experimental MDS combo trial halted early – what we know

NCT ID NCT04878432

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

Summary

This phase 2 study tested adding sabatolimab, an experimental immunotherapy, to standard chemotherapy drugs (azacitidine, decitabine, or oral decitabine) in 39 adults with intermediate to very high risk myelodysplastic syndrome (MDS). The main goal was to check safety, and the trial also looked at how many patients achieved complete remission within 12 months. The study was terminated early, so the full picture is limited, but the data collected helps understand the combination's safety and potential effectiveness.

What this could mean

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

Active substance

sabatolimab (MBG453) plus a hypomethylating agent (azacitidine, decitabine, or oral decitabine/cedazuridine)

What this could lead to

If successful, this combination could offer a new treatment option for people with higher-risk myelodysplastic syndrome (MDS) by improving remission rates.

What could go wrong

The trial was terminated early with only 39 participants, so results are limited. It is unclear if sabatolimab adds meaningful benefit over standard therapy, and side effects are possible.
