Experimental combo aims to outsmart tough leukemia
NCT ID NCT05627232
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests two different drug combinations for people whose acute myeloid leukemia (AML) has returned or not responded to prior treatment. In Part 1, participants receive tazemetostat plus a standard chemotherapy called CPX-351. In Part 2, they get palbociclib before CPX-351. The study enrolls 24 adults and focuses on finding safe doses and watching for side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tazemetostat and CPX-351 (liposomal daunorubicin-cytarabine) in Part 1; palbociclib followed by CPX-351 in Part 2
- What this could lead to
- If successful, this could point toward a new combination treatment for acute myeloid leukemia that has come back or not responded to standard therapy.
- What could go wrong
- This is a very early (Phase 1) trial with only 24 participants, so the main goal is safety, not proof of effectiveness. The combinations may cause serious side effects or fail to improve outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Provide signed and dated informed consent form * Willing to comply with all study procedures and be available for the duration of the study * Male or female \>= 18 years of age * Histologically confirmed acute myeloid leukemia (non-M3) relapsed from or refractory to at least 1 prior line of therapy. Bone marrow aspirate and biopsy within 28 days of screening is acceptable. If no prior bone marrow biopsy is available, bone marrow biopsy must be performed during screening unless: \* If the subject has \>= 20% myeloblasts present in the peripheral blood, a bone marrow biopsy is not necessary to meet this criterion * Treatment with a prior investigational agent is acceptable so long as it has not been administered within 2 weeks of enrollment and any prior adverse effects have resolved to grade 1 or less with the exception of alopecia * Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less * Life expectancy of at least 4 weeks * Must be able to consume oral medication * Subjects must have recovered from the toxic effect of any prior therapy to =\< grade 1 (except alopecia) * Creatine clearance (CrCL) \>= 45 * Total bilirubin \< 2 x upper limit of normal (ULN) * Female subjects of childbearing age must have a negative pregnancy test Exclusion Criteria: * Subjects with acute promyelocytic leukemia * Subjects receiving any active chemotherapy agents (except hydroxyurea). Intrathecal methotrexate and cytarabine are permissible * Subjects whose participation would result in a total cumulative dose of daunorubicin greater than 550 mg/m\^2 or greater than 450 mg/m\^2 if they previously received mediastinal radiation * Subjects with evidence of active central nervous system (CNS) leukemia involvement. Lumbar puncture is not required for enrollment in the absence of neurologic symptoms * Subjects must not be receiving growth factors (except erythropoietin) * Subjects with currently active second malignancy with the exception of nonmelanoma skin cancer, carcinoma in situ of the cervix, resected prostate cancer with Gleason score =\< 6 * Subjects with unstable cardiac disease or uncontrolled arrhythmia * Subjects with other severe concurrent disease which, in the judgement of the investigator, would make the patient inappropriate to receive high-intensity therapy * Subjects who are pregnant or breastfeeding * Subjects with known allergic reactions to components of the study product(s) * Anything that would place the individual at increased risk or preclude the individual's full compliance with or completion of the study
