Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients with non-acute promyelocytic leukemia AML who are experiencing their first or second relapse and are eligible for both low intensity and high dose chemotherapy.

Probably not a fit

Patients who have specific contraindications to either treatment option or those for whom a superior treatment is already available may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, randomized, open-label clinical trial evaluates the effectiveness of high intensity reinduction chemotherapy versus low intensity therapies in patients with relapsed or refractory acute myeloid leukemia (AML). The study aims to provide a pragmatic comparison of these treatment approaches, leveraging recent findings that suggest low-intensity therapies may be comparable to traditional chemotherapy. It is designed to accommodate the variability in patient responses and treatment availability across different regions. The trial is funded by the European Commission and involves multiple participating hospitals.

Why it matters

Potential benefit: If successful, this study could provide a less intensive treatment option for patients with relapsed or refractory AML, potentially improving their quality of life.

How similar studies have gone: Other studies have shown promise in comparing low-intensity therapies with standard chemotherapy, but this specific approach is relatively novel.

* Participation in another clinical trial with any investigational agents within 14 days or 5 drug half-lives (whatever comes first) prior to randomization
* Active infections or other clinical conditions that in the opinion of the investigator make the patient ineligible to receive study treatment.
