Study Endpoints
Primary Endpoints
Part 1 and Part 2: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
Up to 100 days after the last dose of study drug or until the start of a subsequent anticancer therapy, whichever comes first (that is up to 2.3 years)

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.

Part 1: Number of Participants with Dose-Limiting Toxicity (DLTs)
Up to 28 days

Number of participants with dose-limiting toxicity will be assessed. The DLTs are based on drug-related adverse events and defined as any of the following events: infusion-related reactions, non-hematologic toxicity of Grade 3 or higher, or hematologic toxicity.

Part 1: Severity of DLT as Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE)
Up to 28 days

The DLT evaluation period is defined as the first 28 days after a participant's first infusion (Day 1). Severity criteria is based on Grade 1, 2, 3, 4 and 5, will be assessed by the investigator as per below grades. Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening consequences; Grade 5: Death related to adverse event.

Part 2: Overall Response Rate (ORR)
Approximately 2.3 years

ORR is defined as the percentage of participants who have complete response (CR) and incomplete blood count recovery (CRi) (AML) or CR and partial response (PR) (MDS) as per modified International Working Group response (IWGR) criteria.

Secondary Endpoints
Part 1 and Part 2: Serum Concentrations of JNJ-67571244
Approximately 2.3 years
Part 1 and 2: Systemic Cytokine Concentrations
Approximately 2.3 years
Number of Participants with Depletion of CD33-Expressing Cells
Approximately 2.3 years

Part 1: Dose EscalationEXPERIMENTALParticipants will receive JNJ-67571244. The dose levels will be escalated sequentially based on the decisions of the Study Evaluation Team (SET) until the recommended Phase 2 Dose (RP2D) has been identified.
Part 2: Dose ExpansionEXPERIMENTALParticipants in 2 expansion cohorts of acute myeloid leukemia (AML) or either high-risk myelodysplastic syndromes (MDS) or very high-risk MDS will receive JNJ-67571244 at the RP2D determined in Part 1.
