NCT05652335

Brief Summary

The primary purpose of this study is to identify the recommended phase 2 dose (RP2D\[s\]) and schedule(s) to be safe for JNJ-79635322 in Part 1 (dose escalation), and to characterize the safety and tolerability of JNJ-79635322 at the RP2D(s) selected and in disease subgroups in Part 2 (dose expansion).

Outcome Measures

Primary Outcomes (3)

  • Part 1: Number of Participants with Dose-limiting Toxicity (DLT)

    DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.

    Up to 2 years 5 months

  • Parts 1 and 2: Number of Participants with Adverse Events (AEs) by Severity

    An adverse event is any untoward medical occurrence in a clinical study participant that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from grade 1 (mild) to grade 5 (death). Grade 1= mild, Grade 2= moderate, Grade 3= severe, Grade 4= life-threatening and Grade 5= death related to adverse event.

    Up to 2 years 5 months

  • Part 2: Number of Participants with Abnormalities in Laboratory Values

    Number of participants with abnormalities in laboratory values (hematology and chemistry) will be reported.

    Up to 2 Years 5 months

Secondary Outcomes (8)

  • Serum Concentration of JNJ-79635322

    Up to 2 Years 5 months

  • Number of Participants with Presence of Anti-Drug Antibodies to JNJ-79635322

    Up to 2 Years 5 months

  • Preliminary Anticancer Activity of JNJ-79635322 as Defined by International Myeloma Working Group (IMWG) 2016 Response Criteria

    Up to 2 Years 5 months

  • Time to Response (TTR) as Defined by IMWG 2016 Response Criteria

    Up to 2 Years 5 months

  • Duration of Response (DOR) as Defined by IMWG 2016 Response Criteria

    Up to 2 Years 5 months

  • +3 more secondary outcomes

Study Arms (2)

Part 1: Dose Escalation

EXPERIMENTAL

Participants will receive JNJ-79635322. The dose will be escalated sequentially until the recommended phase 2 dose (RP2D) regimen(s) have been identified.

Drug: JNJ-79635322

Part 2: Dose Expansion

EXPERIMENTAL

Participants will receive JNJ-79635322 at the RP2D regimen(s) determined in Part 1.

Drug: JNJ-79635322

Interventions

JNJ-79635322 will be administered as SC injection.
