---|---|
Experimental: Part 1: Dose Escalation
Participants 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.

Drug: JNJ-67571244
JNJ-67571244 will be administered. |
Experimental: Part 2: Dose Expansion
Participants 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.

- Part 1 and Part 2: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: 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) [ Time Frame: 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) [ Time Frame: 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) [ Time Frame: 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.
- Part 1 and Part 2: Serum Concentrations of JNJ-67571244 [ Time Frame: Approximately 2.3 years ]Serum samples will be analyzed to determine concentrations of JNJ-67571244 using a validated immunoassay method.
- Part 1 and 2: Systemic Cytokine Concentrations [ Time Frame: Approximately 2.3 years ]Serum cytokine (Interleukin [IL]-2, IL-6, IL-8, IL-10, and Interferon [IFN]-alpha, IFN-delta with same unit of measurement) concentrations will be measured for biomarker assessment.
- Number of Participants with Depletion of CD33-Expressing Cells [ Time Frame: Approximately 2.3 years ]Number of participants with depletion of CD33-expressing cells will be assessed.
- Part 1 and 2: Concentration of Markers of T-Cell Activation [ Time Frame: Up to 24 days ]Levels of T-cell activation marker CD25 will be reported as measured by flow cytometry and cytometry by time of flight (CyTOF). T-cell activation will also be assessed by measuring cytokine release.
- Part 1 and 2: Number of Participants with JNJ-67571244 Antibodies [ Time Frame: Week 1 (Day 1) up to post treatment Week 8 ]Anti-JNJ-67571244 antibodies will be evaluated in serum samples collected from all participants and the titer of confirmed positive samples will be reported.
- Part 1 and Part 2: Duration of response (DOR) [ Time Frame: Approximately 2.3 years ]DOR is calculated from date of initial documentation of a response (complete response (CR) and incomplete blood count recovery (CRi) (AML) or CR and partial response (PR) [MDS]) to the date of first documented evidence of relapse, defined in disease-specific response criteria, or death, whichever occurs first.
- Part 1 and Part 2: Time to response (TTR) [ Time Frame: Approximately 2.3 years ]TTR defined for the responders as the time from the date of first dose of study drug to the date of initial documentation of a response (CR and CRi [AML] or CR and PR [MDS]), as defined in the disease-specific response criteria.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
A diagnosis of:
a) Acute Myeloid Leukemia (AML) according to the World Health Organization 2008 criteria with relapsed or refractory disease and ineligible for or have exhausted standard therapeutic options b) high-risk or very high-risk Myelodysplastic Syndrome (MDS) according to International Prognostic Scoring System (IPSS-R) and relapsed or refractory after at least 1 course of hypomethylating therapy and ineligible for or have exhausted standard therapeutic options per investigator discretion should be included
- Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1
- Women of childbearing potential must have a negative pregnancy test at screening and prior to the first dose of study drug using a highly sensitive pregnancy test (either serum or urine beta human chorionic gonadotropin [beta-hCG])
-
Chemistry laboratory parameters within the following range during screening:
a) aspartate transaminase (AST) and alanine aminotransferase (ALT) less than or equal to (<=) 3* upper limit of normal (ULN), b) Total bilirubin <=1.5*ULN; participants with congenital bilirubinemia, such as Gilbert's syndrome, may enroll if conjugated bilirubin is within normal range, c) Creatinine clearance calculated or measured creatinine clearance greater than or equal to (>=) 30 milliliters per minute (mL/min)
-
Before the first dose of study drug:
- Women of childbearing potential and fertile men who are sexually active must agree to use a highly effective method of contraception (less than [<] 1 percent {%} year failure rate from the time of signing the informed consent form [ICF]) during the study and for 90 days after the last dose of study drug. Contraception must be consistent with local regulations regarding the use of birth control methods for participants participating in clinical trials. 1) Participant must agree to practice a highly effective method of contraception (failure rate of <1% per year when used consistently and correctly). Examples of highly effective contraceptives include: a) user-independent methods: implantable progestogen-only hormone contraception associated with inhibition of ovulation; intrauterine device; intrauterine hormone-releasing system; vasectomized partner; b) user-dependent methods: combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, and transdermal; progestogen-only hormone contraception associated with inhibition of ovulation: oral and injectable, c) In addition to the highly effective method of contraception, a man: 1) Who is sexually active with a woman of childbearing potential must agree to use a barrier method of contraception (for example, condom with spermicidal foam/gel/film/cream/suppository), 2) Who is sexually active with a woman who is pregnant must use a condom, c) Women and men must agree not to donate eggs (ova, oocytes) or sperm, respectively, during the study and for 90 days after the last dose of study drug
