Description of intervention(s) / exposure
Treatment: Drugs - Azacitidine
Treatment: Drugs - Cusatuzumab

Experimental: Azacitidine 75 mg/m^2 and Cusatuzumab 10 mg/kg - Participants will receive azacitidine 75 milligram per meter square (mg/m\^2) subcutaneously (SC) or intravenously (IV) on Day 1 through Day 7 and cusatuzumab 10 milligram per kilogram (mg/kg) IV on Day 3 and Day 17 of each 28-day cycle in Part 1. Part 1 findings will be reviewed by a data review committee.

Experimental: Azacitidine 75 mg/m^2 and Cusatuzumab 20 mg/kg - Participants will receive azacitidine 75 mg/m\^2 SC or IV on Day 1 through Day 7 and cusatuzumab 20 mg/kg IV on Day 3 and Day 17 of each 28-day cycle in Part 1. Part 1 findings will be reviewed by a data review committee.


Treatment: Drugs: Azacitidine
Azacitidine SC or IV will be administered at a standard dose of 75 mg/m\^2 on days 1-7 of each cycle.

Treatment: Drugs: Cusatuzumab
Cusatuzumab IV will be administered as 10 mg/kg or 20 mg/kg on days 3 and 17 of each cycle.

Eligibility
Key inclusion criteria
* Acute myeloid leukemia (AML) according to World Health Organisation (WHO) 2016 criteria and fulfilling all of the following criteria that defines those who are "not candidates for intensive chemotherapy":

1. greater than or equal to (>=)75 years of age or
2. less than (<) 75 years of age with at least one of the following comorbidities: Eastern Cooperative Oncology Group (ECOG) Performance Status of 2; Severe cardiac comorbidity defined as congestive heart failure or ejection fraction less than or equal to (<=) 50 percent (%); Severe pulmonary comorbidity defined as documented pulmonary disease with lung diffusing capacity for carbon monoxide (DLCO) <=65% of expected, or forced expiratory volume in 1 second (FEV1) <=65% of expected or dyspnea at rest requiring oxygen; Moderate hepatic impairment defined according to NCI organ dysfunction classification criteria (total bilirubin >=1.5 up to 3 times upper limit of normal [ULN]); Creatinine clearance <45 milliliter per minute per 1.73 meter square (mL/ min/1.73 m^2); Comorbidity that, in the Investigator's opinion, makes the participant unsuitable for intensive chemotherapy and must be documented and approved by the Sponsor before randomization
* De novo or secondary AML
* Previously untreated AML (except: emergency leukapheresis, hydroxyurea, and/or 1 dose of cytarabine [example: 1-2 gram per meter square {g/m^2}] during the Screening Phase to control hyperleukocytosis. These treatments must be discontinued >=24 hours prior to start of study drug). Empiric all trans retinoic acid (ATRA) treatment for presumed acute promyelocytic leukemia (APL) is permitted but APL must be ruled out and ATRA must be discontinued >=24 hours prior to the start of study drug
* Not eligible for an allogeneic hematopoietic stem cell transplantation
* ECOG Performance Status score of 0, 1 or 2
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Acute promyelocytic leukemia
* Leukemic involvement or clinical symptoms of leukemic involvement of the central nervous system
* Use of immune suppressive agents for the past 4 weeks before the first administration of cusatuzumab on Cycle 1 Day 3. 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 myelodysplastic syndrome (MDS)
* Active malignancies (that is, progressing or requiring treatment in the last 24 months) other than the disease being treated under the study
* Any active systemic infection
* Known allergies, hypersensitivity, or intolerance to cusatuzumab or azacitidine or its excipients (that is, mannitol, an excipient of azacitidine)
