FHD-286 With Low-Dose Weekly Decitabine/Venetoclax in Patients With Acute Myeloid Leukemia
This is a Phase 1, uncontrolled, single-arm, open-label, nonrandomized, dose escalation, study of Decitabine (DAC)+Venetoclax (VEN)+FHD-286 in participants with newly diagnosed Acute Myeloid Leukemia (AML) classified as adverse risk per the 2022 European Leukemia Net (ELN) criteria or AML that has progressed after one prior line of therapy.
• Newly diagnosed adverse risk AML, including Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML), per the 2022 ELN criteria, with a histopathologic diagnosis confirmed by hematopathology review OR AML that has progressed after 1 prior line of therapy with ≥5% blasts
• Aged ≥75 years, or aged 18-74 years and either refuse to receive intensive induction chemotherapy or are not a candidate for intensive induction chemotherapy due to one or more of the following comorbidities:
∙ Eastern Cooperative Oncology Group performance status (ECOG PS) of 2 or 3
‣ Cardiac history of congestive heart failure requiring treatment, ejection fraction ≤50%, or chronic stable angina pectoris
‣ Diffusing capacity of the lung for carbon monoxide ≤65% or forced expiratory volume in 1 second ≤65%
‣ Creatinine clearance ≥30 mL/min to \<45 mL/min
‣ Moderate hepatic impairment with total bilirubin \>1.5 to ≤3.0×upper limit of normal (ULN)
‣ Any other comorbidity that the investigator judges to be incompatible with intensive chemotherapy
• Bone marrow blasts ≥10%
• Have not received a hypomethylating agent (HMA) or VEN for their disease under study
• No other disease-directed therapy, except hydroxyurea or cytarabine, and including experimental or investigational drug therapy, for at least 14 days before study entry
• ECOG PS:
∙ New diagnosed AML:
⁃ 75 years: ≤2
• 18 years to \<75 years: ≤3
‣ AML that has progressed after 1 prior line of therapy (Any age):
⁃ 3 if R/R AML
• Life expectancy ≥3 months
• Adequate end organ function, defined as:
∙ Adequate hepatic function, including:
⁃ Serum total bilirubin ≤3.0×ULN, unless considered due to advanced hematologic malignancy involvement or documented Gilbert syndrome with direct bilirubin ≤1.5×ULN
• Aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase ≤3.0×ULN, unless considered due to advanced hematologic malignancy involvement
‣ Prothrombin time ≤1.5×ULN or international normalized ratio ≤1.4
‣ Activated partial thromboplastin time ≤1.5×ULN Note: Individuals who have been receiving a stable dose of anticoagulation therapy without bleeding episodes for ≥12 weeks may be considered for the study
‣ No known portal vein thrombosis
‣ Glomerular filtration rate (GFR) ≥30 mL/min (based on a contemporary, widely accepted, and clinically applicable equation that estimates GFR or a measure of GFR)
• Adequate cardiovascular, respiratory, and immune system function as evidenced by the below criterion and in the opinion of the investigator:
• a. Left ventricular ejection fraction (LVEF) of ≥40% by echocardiogram (ECHO)
⁃ White blood cell count ≤20×10\^9/L (treatment with hydroxyurea or cytarabine ≤1 g/m2 to achieve this count is allowed before the start of study treatment and for up to 28 days after the start of study treatment)
⁃ Agree to abide by dietary and other considerations required during the study
⁃ Ability to understand and willingness to sign a written informed consent form and complete study-related procedures
