Testing bleximenib for treating acute leukemia

Is this trial a fit for you?

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

What this trial studies

This study aims to evaluate the safety, tolerability, and efficacy of bleximenib in patients with acute leukemia. It consists of two phases: the first phase focuses on determining the recommended dose through dose escalation and expansion, while the second phase assesses the drug's effectiveness at this dose. Participants include adolescents and adults with relapsed or refractory acute leukemia who have specific genetic alterations. The study is designed to provide insights into a new treatment option for this challenging condition.

Inclusion Criteria:

Phase 1:

* Relapsed or refractory (R/R) acute leukemia and has exhausted, or is ineligible for, available therapeutic options
* Acute leukemia harboring histone-lysine N-methyltransferase 2A (KMT2A), nucleophosmin 1 gene (NPM1) or nucleoporin 98 gene or nucleoporin 214 gene (NUP98 or NUP214) alterations

Phase: 2

* Participants greater than 18 years are eligible
* Must have had an initial diagnosis of acute myeloid leukemia (AML) per the WHO 2022 classification criteria and have relapsed/refractory disease

* Pretreatment clinical laboratory values meeting the following criteria: (a) Hematology: white blood cell (WBC) count \<= 20\*10\^9/liter (L) and (b) renal function; For adult participants, estimated or measured glomerular filtration rate \>= 30 milliliter per minute (mL/min) per four variable MDRD equation. For pediatric participants an estimated or measured glomerular filtration rate \>=40 mL/min per the CKiD (Chronic Kidney Disease in Children) Schwartz formula
* Eastern Cooperative Oncology Group (ECOG) performance status grade of 0, 1 or 2. Pediatric participants only: Performance status \>=70 by Lansky scale (for participants \< 16 years of age) or \>=70 Karnofsky scale (for participants \>=16 years of age)
* A female of childbearing potential must have a negative highly sensitive serum beta-human chorionic gonadotropin at screening and within 48 hours prior to the first dose of study treatment
* Participant must agree to all protocol required contraception requirements and avoid sperm or egg donations or freezing for future reproductive use while on study and for 90 days (males) or 6 months (females) after the last dose of study treatment

Exclusion Criteria:

* Acute promyelocytic leukemia, diagnosis of Down syndrome associated leukemia or juvenile myelomonocytic leukemia according to World Health Organization (WHO) 2016 criteria
* Active central nervous system (CNS) disease
* Prior solid organ transplantation
* QTc according to Fridericia's formula (QTcF) for males \>= 450 millisecond (msec) or for females \>= 470 msec. Participants with a family history of Long QT syndrome are excluded
* Exclusion criteria related to stem cell transplant: a. Received prior treatment with allogenic bone marrow or stem cell transplant \<=3 months before the first dose of study treatment ; b. Has evidence of graft versus host disease; c. Received donor lymphocyte infusion \<=1 month before the first dose of study treatment; d. Requires immunosuppressant therapy (exception: daily doses \<=10 milligrams (mg) prednisone or equivalent are allowed for adrenal replacement)
* Prior cancer immunotherapy within 4 weeks prior to enrollment or blinatumomab within 2 weeks prior to enrollment. Additional prior cancer therapies must not be given within 4 weeks prior to enrollment or 5 half-lives of the agent (whichever is shorter)
