A Phase 1 interventional study of Azacitidine and Laboratory Biomarker Analysis in Acute Myeloid Leukemia With t(9;11)(p22.3;q23.3); MLLT3-KMT2A, Fibroblast Growth Factor Basic Form Measurement and FLT3 Internal Tandem Duplication, sponsored by Northwestern University. Active, not recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-10-21.

The purpose of this study is to find the appropriate dose of the study drug nintedanib when combined with azacitidine and the associated side effects of the combination in older adults with AML characterized by HOX gene overexpression who are not interested in or not considered fit for standard intensive chemotherapy. The use of the study drug nintedanib in this study is investigational. Investigational means that this medication has not yet been approved by the FDA to treat this type of cancer. Azacitidine received FDA Approval in 2004 for myelodysplastic syndrome (a blood cancer related to AML) and has a National Comprehensive Cancer Network (NCCN) guideline recommendation for treatment of older adults who are not candidates for or decline intensive remission induction therapy. We expect participation to continue in this study based on each participant's response to the drug, and ability to tolerate treatment. Participants may continue to receive study treatments for 6 cycles (one cycle is 28 days long). If the 6 cycles of treatment is completed, participants may be moved on to a maintenance phase of treatment. Treatment will continue until the participant's leukemia gets worse, or they experience serious side effects, have a break in treatment for more than 56 days or the study doctor feels it is best for study treatments to stop.
PRIMARY OBJECTIVES:
I. To identify maximum tolerated dose (MTD) of nintedanib for combination treatment of nintedanib and azacytidine (5-azacitidine) in the treatment of newly diagnosed and relapsed/refractory acute myeloid leukemia with HOX overexpression and who are ineligible for intensive chemotherapy.
SECONDARY OBJECTIVES:
I. Adverse events (AEs) including dose limiting toxicities (DLTs) will be assessed according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 4.03.
II. To determine median overall survival. III. To determine complete remission (CR) rate.
EXPLORATORY OBJECTIVES:
I. To determine composite CR rate (CR + complete remission with incomplete platelet recovery [CRp] + complete remission with incomplete hematological recovery [Cri]).
II. To determine duration of confirmed response. III. To determine event free survival. IV. To determine leukemia free survival. V. To establish correlation between response and pre-treatment Fgf2 levels and change in Fgf-2 levels during treatment.
OUTLINE: This is a dose-escalation study of azacitidine.
Participants receive nintedanib orally (PO) twice daily (BID) on days 1-28 and azacitidine intravenously (IV) or subcutaneously (SC) on days 1-7. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 courses, participants may discontinue treatment, receive nintedanib every 4-8 weeks, or receive nintedanib and azacitidine every 4-8 weeks.
After completion of study treatment, participants are followed up at every 3 months for 12 months and then every 6 months for up to 24 months.

ESCLATION COHORT: Patients must have a diagnosis of newly diagnosed and/ or relapsed/refractory AML with any of the following:
Note: Relapsed or refractory AML is defined as either:
EXPANSION COHORT: Patients must have a diagnosis of newly diagnosed AML with any of the following:
Females of child-bearing potential (FOCBP) and males must agree to use medically acceptable method of contraception (e.g. a method which results in a low failure rate of less than 1% per year when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices or vasectomized partner for participating females, latex condoms for participating males, sexual abstinence) prior to study entry, for the duration of study participation, and for 3 months following completion of therapy; should a female patient become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; if the female partner of a male participant becomes pregnant he should inform the treating physician and the female partner should contact her treating physician immediately
NOTE: A FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
Exclusion Criteria:
Patients who have received chemo-, hormone-, radio or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 14 days prior to start of treatment or those who have not recovered from adverse events attributed to the agent to grade 1 or baseline
Exceptions for prior treatments are:
Leukapheresis for leukocytosis (no wash out period required; it can be continued during the study)
Patients who have received any other investigational product within14 days of treatment are not eligible for this study; a wash out period ? 14 days or 5 half- lives (whichever is greater) is required from investigational treatment, prior to start of study treatment; please Note:
Patients who have significant cardiovascular diseases are not eligible; these are:
Patients who have an uncontrolled intercurrent illness including, but not limited to any of the following, are not eligible:
Participants receive nintedanib PO BID on days 1-28 and azacitidine IV or SC on days 1-7. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 courses, participants may discontinue treatment, receive nintedanib every 4-8 weeks, or receive nintedanib and azacitidine every 4-8 weeks.
