  • Research summary

    Acute leukemias are characterized by uncontrolled proliferation of immature white blood cells (WBCs) in bone marrow (soft, fatty tissue inside of bone cavities), peripheral blood and/or other sites in the body. Acute myeloid leukemia (AML) & Myelodysplastic neoplasms (MDS) are cancers in which abnormal myeloid cells, called blasts, grow uncontrollably, instead of developing into cells that fight infections & help healing.

    JNJ-89853413 (CD33xVδ2) is a bispecific antibody* that binds CD33 protein on AML & MDS blast cells & the Vδ2 chain on Vγ9Vδ2 T-cells. The goal of binding these two cells together is that the T-cells will selectively kill cancer cells.
    *Type of protein that binds to other proteins & fights off an infection.

    In this study, researchers want to determine the safety & tolerability of JNJ-89853413 & to identify safe doses in participants with relapsed or refractory (R/R) AML or R/R higher-risk types of MDS.

    Participants aged 18 years or older or those who are at least the age of majority diagnosed with R/R AML or R/R higher-risk types of MDS.

    Study will be conducted in 2 parts:
    Part 1 (Dose Escalation): In part 1, participants will get JNJ-89853413 with increasing doses. The goal of increasing dose is to study safety of each dose & to establish a safe dose for further evaluation in part 2.
    Part 2 (Cohort Expansion): Participants will get treatment at the recommended dose & schedule of JNJ-89853413 established from part 1.
    Study will consist of a screening period followed by a treatment period. During treatment period, participants will be treated with JNJ-89853413 until worsening of AML/MDS, serious side effects, or withdrawal from study. After discontinuation of treatment, participants will be followed to monitor their health.

    Safety assessments include blood tests, vital sign measurements, & physical exams. Blood samples will be taken at multiple timepoints to understand how the body responds to treatment.
