New drug cocktail aims to beat back aggressive leukemia in older adults
NCT ID NCT05260528
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests whether a newer chemotherapy drug called CPX-351 works better than standard chemo for adults aged 50 and older with a hard-to-treat form of acute myeloid leukemia (AML). About 248 people will be randomly assigned to receive either CPX-351 or standard chemo. The main goal is to see if CPX-351 leads to deeper remissions with less cancer left behind in the bone marrow.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CPX-351 (a combination of two chemotherapy drugs, daunorubicin and cytarabine, in a liposomal formulation)
- What this could lead to
- If CPX-351 works better than standard chemo, it could become a new first-line treatment for older adults with harder-to-treat AML, improving remission rates and reducing relapse.
- What could go wrong
- This is a phase 2 trial, so results are still early. CPX-351 may not prove superior to standard chemo, and both treatments have serious side effects like infection and organ damage.

Patient must have adequate organ function as indicated detailed with laboratory values in the section IV of the protocol 10. Female patient of childbearing potential with a negative serum pregnancy test (β-hCG) within 72 hours prior to receiving the first dose of CPX-351 or 7+3. Female patient who is not actively breastfeeding at the time of study entry. 11. Female patient is either post-menopausal, free from menses for \> 2 years, surgically sterilized or willing to use 2 adequate barrier methods of contraception to prevent pregnancy, or agrees to not become pregnant throughout the study, starting with study screening 12. Male patient agrees to use an adequate method of contraception for the duration of the study. Men should be advised not to father a child while receiving CPX-351 or 7+3 and for 3 months after the last dose of study treatment . 13. Patient is available for periodic blood sampling, study related assessments, and appropriate clinical management at the treating institution for the duration of the study. 14. Patient has the ability to understand and willingness to sign an informed consent form indicating the investigational nature of the study. 15. Patient registered to the French Social Security. Exclusion Criteria: 1. Prior history of documented MDS, MPN or MDS/MPN, tAML 2. Prior history of radiation therapy or chemotherapy for a solid tumor or lymphoma (exceptions to be considered: local radiotherapy for prostate cancer) 3. Patient has active and uncontrolled infection. 4. Patient has uncontrolled intercurrent illness or circumstances that could limit compliance with the study, including but not limited to the following: symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, pancreatitis, or psychiatric or social conditions that may interfere with patient compliance. 5.
