Can a modified enzyme starve Hard-to-Treat blood cancers?
NCT ID NCT02732184
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This phase 1 trial is testing an investigational drug called AEB1102 in adults with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) that has returned or stopped responding to standard treatments. AEB1102 is a modified human enzyme that breaks down arginine, an amino acid that cancer cells may depend on to grow. The study aims to find the highest safe dose and to see how the drug affects blood amino acid levels and whether it has any anti-tumor effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AEB1102 (Co-ArgI-PEG), a modified human enzyme designed to break down arginine, an amino acid that cancer cells may need to grow.
- What this could lead to
- If AEB1102 proves safe and shows anti-cancer activity, it could become a new treatment option for patients with hard-to-treat AML or MDS who have run out of standard options.
- What could go wrong
- This is an early, small phase 1 trial focused on safety and dosing, so it is not yet known if AEB1102 will effectively fight the cancer. Possible side effects are still being evaluated.
