What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
