- •Criterion numbering modified per Amendment 1 3.
- •De novo or secondary AML;
- •Criterion modified per Amendment 1 4.
- •Previously untreated AML (except: emergency leukapheresis, hydroxyurea, and /or 1 dose of cytarabine [eg, 1-2g/m^2] during the screening phase to control hyperleukocytosis. Theses treatments mst be discontinued ≥ 24 hours prior to start of study drug). Empiric all trans retinoic acid (ATRA) treatment for presumed acute promyelocytic leukemia (APL) is permited but APL mus be ruled out and ATRA mus be discontinued ≥ 24 hours prior to the start of the study drug;

- •Criterion numbering modified per Amendment 1 6.
- •ECOG Performance Status score of 0, 1 or
- •Criterion numbering modified per Amendment 1 7.
- •The following clinical laboratory values at screening: ● Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) <3 times ULN; for participants with leukemic infiltration of the liver (documented by biopsy or imaging), AST and ALT <5 times ULN is permitted ● Total bilirubin ≤ 3 times ULN unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin or in case of liver infiltration by AML (documented by biopsy or imaging) serum total bilirubin <5 times ULN ● Creatinine Clearance >30 mL/min (by MDRD formula)
- •Criterion numbering modified per Amendment 1 8.
- •A woman must be either: ● Not of childbearing potential: postmenopausal (>45 years of age with amenorrhea for at least 12 months); ● Of childbearing potential and practicing a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for participants participating in the clinical study while receiving study tratment and for at least 3 months after the last dose of study treatment. A woman of childbearing potential must have a negative highly-sensitive serum (β-human chorionic gonadotropin [β-hCG]) or urine pregnancy test at screening. A woman fo childbearing potential must agree to not donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study treatment and for 3 months after the last dose of study treatment. Note: If the childbearing potential changes after start of the study (eg, woman who is not heterosexually active becomes active, premenarchal woman experiences menarche) a woman must begin a highly effective method of birth control, as described above.
- •Criterion modified per Amendment 1 9.
- •A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control eg, either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository for at least 3 months after last study treatment. ● Must agree to not donate sperm during the study treatment and for 3 months after the last dose of study treatment. ● Not plan to father a chld during the study treatment and for 3 months after the last dose os study treatment.
排除标准
- •Criterion modified per Amendment 1 1.
- •Acute promyelocytic leukemia
- •Known allergies, hypersensitivity, or intolerance to cusatuzumab or azacitidine or its excipients (ie, mannitol, an excipient of azacitidine).
- •Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (eg, compromise the well-being) or physical limitations that could prevent, limit, or confound the protocol-specified assessments.
- •Criterion modified per Amendment 1 12.
- •Major surgery, (eg, requiring general anesthesia) within 4 weeks prior to initiation of the study.
- •Women who are breastfeeding.
- •Received a live, attenuated vaccine within 4 weeks prior to initiation of study treatment. NOTE: Investigators should ensure that all study enrollment (inclusion/exclusion) criteria have been met at screening and prior to the first dose of study intervention. If a participant's clinical status changes (including any available laboratory results or receipt of additional medical records) after screening but before the first dose of study intervention is given such that he or she no longer meets all eligibility criteria, then the participant should be excluded from participation in the study.
- •Leukemic involvement or clinical symptoms of leukemic involvement of the central nervous system.
- •Criterion modified per Amendment 1 3.
- •Use of immune suppressive agents for the past 4 weeks before the first administration of cusatuzumab on Cycle 1 Day
- •For regular use of systemic corticosteroids, participants may only be included if free of systemic corticosteroids for a minimum of 5 days before the first administration of cusatuzumab. Treatment of adrenal insufficiency with physiologic replacement doses of corticosteroids are allowed.
- •Prior treatment with a hypomethylating agent for treatment of AML or MDS
- •Criterion modified per Amendment 1 5.
- •Active malignancies (ie, progressing or requiring treatment in the last 24 months) other than the disease being treated under study. The only allowed exceptions are: ● Non-melanoma skin cancer treated within the last 24 months that is considered completely cured ● Adequately treated breast lobular carcinoma in situ and breast ductal carcinoma in situ ● Adequately treated cervical carcinoma in situ without evidence of disease ● History of localized breast cancer and receiving antihormonal agents, or history of localized prostate cancer (N0M0) and receiving androgen deprivation therapy ● Malignancy that is considered cured with minimal risk of recurrence
- •Criterion modified per Amendment 1 6.
- •Any active systemic infection

- •Criterion modified per Amendment 1 8.
- •Active hepatitis B or C infection or other clinically active liver disease Seropositive for hepatitis B: defined by a positive test for hepatitis B surface antigen [HBsAg]. Participants with resolved infection (ie, participants who are HBsAg negative with antibodies to total hepatitis B core antigen [anti-HBc] with or without the presence of hepatitis B surface antibody [anti-HBs]) must be screened using real-time polymerase chain reaction (RT-PCR) measurement of hepatitis B virus (HBV) DNA levels. Those who are RT-PCR positive will be excluded. Participants with serologic findings suggestive of HBV vaccination (antiHBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by RT-PCR. Known Hepatitis C infection or positive serologic testing for Hepatitis C (anti-HCV antibody)
- •New York Heart Association Class IV heart failure or ongoing unstable angina
