A Phase I/II , Multicenter, Open Label Clinical Study Evaluating the Safety, Pharmacokinetics, and Efficacy of the Combination of the Menin Inhibitor BN104 for the Treatment of Patients With Acute Myeloid Leukemia

The Phase I/II trial is to learn the safety, pharmacokinetics, and preliminary efficacy of BN104 taken twice daily combined with Intensive Chemotherapy or Venetoclax/Azacitidine in patients with acute myeloblastic leukemia.

Inclusion: Have been fully informed about the study and have voluntarily signed the ICF; Patients with newly diagnosed primary AML according to the 2022 World Health Organization (WHO) criteria (Groups A and B) or patients with relapsed/refractory AML who have been previously treated with menin inhibitor monotherapy (Group C) and have an intermediate or poor prognosis according to the 2022 ELN Risk Stratification, as well as a defined combination of NPM1 mutation or NUP98 rearrangement or KMT2A rearrangement; Peripheral blood leukocyte count ≤ 25 x 109/L (limited to patients enrolled in groups B and C, where hydroxyurea is allowed to control peripheral blood leukocyte count); Aged 18 years or older; ECOG (GroupA and B:0,1,2; GroupC:0,1,2,3); For patients in group B, unfit for intensive chemotherapy is defined as:≥75 years of age or;Age ≥18 years and age <75 years with any of the following co-morbidities;ECOG score of 2 or 3;Cardiac history: congestive heart failure requiring treatment, or ejection fraction ≤50%, or chronic stable angina;DLCO ≤ 65% or FEV1 ≤ 65%;Creatinine clearance ≥30 ml/min and <45 ml/min;Liver injury total bilirubin > 1.5 x ULN but ≤ 3 x ULN; For patients in group C, previous failed treatment with menin inhibitors is required; adequate hepatic, renal, and cardiac function, as defined:Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x upper limit of normal range (ULN);Total bilirubin ≤ 1.5 x ULN* and in patients with Gilbert disease, total bilirubin ≤ 3 x ULN;Creatinine clearance ≥ 45 ml/min* as estimated by the Cockcroft-Gault formula (if <45 ml/min, enrollment is allowed if creatinine ≤ 130 µmol/L); Left ventricular ejection fraction ≥ 45%*; Note: In Phase II studies, ALT or AST may be relaxed to ≤5 x ULN if the investigator assesses that the elevated ALT or AST is due to leukemia invasion of the liver;For patients <75 years of age enrolled in Group B, total bilirubin ≤ 3 × ULN, creatinine clearance ≥ 30 ml/min, or left ventricular ejection fraction < 50% are allowed; for patients with D-dimer test result > 5×ULN in the screening period, relevant tests (e.g. review of coagulation function after a certain time interval, ultrasound of deep veins of the lower limbs, etc.) are required to exclude deep vein thrombosis, hypercoagulable state of blood and disseminated intravascular coagulation before enrollment; expected survival of more than 12 weeks as judged by the investigator; Be willing to attend study visits as required by the study protocol; female patients of childbearing potential or male patients whose female partners are of childbearing potential must agree to use an effective method of contraception, such as a double-barrier method of contraception, condoms, oral or injectable contraceptives, and intrauterine devices (IUDs), for the duration of the study and within 30 days of the last study dose. Postmenopausal women (>45 years of age and menopause of more than 1 year) and surgically sterilized women are exempt from this condition.

Exclusion: for patients in Group C, prior anti-leukemia therapy, including chemotherapy, radiotherapy, hormonal therapy, targeted therapy, or immunotherapy, administered less than 2 weeks or 5 half-lives (whichever is shorter) prior to the start of study treatment; for patients who have undergone autologous hematopoietic stem cell transplantation or CAR-T therapy within 60 days prior to the start of study treatment, or have not recovered from toxicity associated with ASCT or CAR-T therapy Exclusion will be required for those who have had an allogeneic HSCT within 100 days prior to the start of study treatment, or if the patient still has a combination of active acute and chronic graft-versus-host disease, or if the patient still requires immunosuppressive therapy; pre-existing treatment with targeted menin (for Group A and B patients); patients who have had a chest CT within 1 month prior to screening and suggestive of pulmonary nodules need to undergo T-SPOT (T-cell spotting test for tuberculosis infection) during the screening period, and those with positive results need to be excluded (no additional tests are required if no chest CT has been performed within 1 month prior to screening); uncontrolled active infection:Patients with non-serious infectious complications (e.g., oral Candida infection or uncomplicated urinary tract infection, etc.) for which oral/topical anti-infective therapy is being applied may be enrolled;Patients with severe infections requiring hospitalization or intravenous antibiotic therapy within 14 days prior to enrollment, patients with no evidence of infection, and patients receiving prophylactic anti-infective, antifungal, or antiviral therapy for prolonged neutropenia may be enrolled;Patients treated with intravenous antibiotics or hospitalized for febrile neutropenia, but no evidence of infectious etiology is found, and patients with a normal temperature for more than 72 hours without antipyretic medication may be enrolled; a known history of clinically significant liver disease, including viral or other hepatitis or cirrhosis:Positive hepatitis B surface antigen (HBsAg) serology requires a negative hepatitis B virus (HBV) DNA test for enrollment; For patients with hepatitis C virus (HCV) antibody serology positive, a negative HCV RNA test result is required for enrollment; known human immunodeficiency virus (HIV) infection; the patient has suffered from other malignant tumors within the past 5 years, except for radically treated basal cell carcinoma of the skin, carcinoma in situ of the breast or carcinoma in situ of the cervix; patients with known dysphagia, short bowel syndrome, gastroparesis, or other conditions that limit oral drug intake or gastrointestinal absorption; patients with a history of severe allergy to menin inhibitors or hypersensitivity to any component of BN104; meet any of the following cardiac-related criteria:Hereditary long QT interval syndrome or QTcF > 450 msec;Various clinically significant cardiovascular diseases, including acute myocardial infarction, unstable angina pectoris, coronary artery bypass grafting within 6 months prior to enrollment, congestive heart failure graded by the New York Heart Association (NYHA) as grade 2 or higher (inclusive); have received prior anti-leukemia therapy (for patients in Groups A and B), except for the following: use of hydroxyurea or leukocyte monocloning for control of white blood cell count, or treatment with all-trans retinoic acid due to initial suspicion of acute promyelocytic leukemia, or use of nondemethylating medications for the treatment of MDS; any other disease, metabolic abnormality, physical examination abnormality, or clinically significant laboratory test abnormality that, in the judgment of the investigator, gives reason to suspect that the patient has a disease or condition that is inappropriate for the use of the study medication, or that will interfere with the interpretation of the results of the study, or that places the patient at high risk; have active central nervous system (CNS) leukemia; pregnant (positive screening pregnancy test) or lactating females; pre-existing non-hematologic toxicities that have not returned to grade 0 or 1 (except alopecia areata); inadequate patient compliance with participation in this clinical study as judged by the investigator.
