Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with newly diagnosed AML (ages 18-70) or with CLL/SLL (ages 65 and over) who have no measurable disease left after treatment. It compares standard and reduced treatment.

Age
AML: 18-70 years. CLL: 65 years and over.
Sex
All genders can join.
Disease stage
AML: newly diagnosed, intermediate risk (ELN 2022), in remission after 1-2 cycles of chemotherapy. CLL/SLL: first treatment, with a fixed-duration regimen.
Earlier treatment
AML: intensive induction chemotherapy, 1-2 cycles. CLL: first-line fixed-duration treatment only; people with relapsed or refractory CLL cannot join.
Biomarker or test result
AML: no measurable residual disease (MRD-negative, below 0.1%) in bone marrow. CLL: undetectable MRD in blood at two checks, below 10-4 and below 10-5.

Main reasons for not taking part

  • AML with favorable or adverse ELN 2022 risk
  • Acute promyelocytic leukemia, or earlier MDS, MPN or CML
  • AML with known BCR-ABL1 or high-risk FLT3-ITD
  • CLL with del(17p) and/or mutated TP53
  • Relapsed or refractory CLL, or an unusual cell type that cannot be tested for MRD

About the trial

What the trial wants to find out

● MRD registry, Arm A (AML): To determine the frequency of MRD negative complete remission (CR), CR with incomplete hematologic recovery (CRi) and CR with partial hematologic recovery (CRh) in the registered cohort of AML patients with ELN intermediate risk who have been treated with standard induction chemotherapy for 1-2 cycles.

Read full original descriptionShow less

● MRD registry, Arm B (CLL): To determine the frequency of undetectable MRD (uMRD) in treatment-naive CLL patients who have been treated with fixed duration treatments for 7 or 9 cycles, depending on the treatment regimen.

● RESOLVE trial, Arm A (AML): To evaluate non-inferiority of non-alloHCT consolidation (group 2) compared to alloHCT consolidation (group 1) with regard to overall survival (OS) in intermediate-risk AML patients who tested MRD-negative after 1-2 cycles of induction chemotherapy.

● RESOLVE trial, Arm B (CLL): To demonstrate a lower average overall adverse event burden score based on physician assessment during the first 6 months after randomization in patients with CLL achieving uMRD who stopped treatment at the time of randomization (treatment group 4) compared to those completing fixed-duration treatment as per standard of care (treatment group 3).
