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).

Conditions
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
EXPERIMENTALParticipants will receive JNJ-79635322. The dose will be escalated sequentially until the recommended phase 2 dose (RP2D) regimen(s) have been identified.
Part 2: Dose Expansion
EXPERIMENTALParticipants will receive JNJ-79635322 at the RP2D regimen(s) determined in Part 1.
Interventions
JNJ-79635322 will be administered as SC injection.

- Must have an Eastern Cooperative Oncology Group (ECOG) status of 0 or 1
- Have measurable disease at screening as defined by at least 1 of the following: a) Serum M-protein level greater than or equal to (\>=) 0.5 grams per deciliter (g/dL); or b) Urine M-protein level \>=200 milligrams (mg)/24 hours; or c) Light chain multiple myeloma: Serum immunoglobulin (Ig) free light chain (FLC) \>=10 milligrams per deciliter (mg/dL) and abnormal serum Ig kappa lambda FLC ratio; d) For participants without measurable disease in the serum, urine, or involved FLC, presence of 1 or more focus of extramedullary disease (EMD) which meets the following criteria: extramedullary plasmacytoma not contiguous with a bone lesion, at least 1 lesion \>=2 centimeter \[cm\] (at its greatest dimension) diameter on whole body Positron Emission Tomography and Computed Tomography (PET-CT) Scans (or whole body magnetic resonance imaging \[MRI\] approved by sponsor), and not previously radiated (Part 2C participants are not required to have measurable disease)
- For participants with previously treated AL amyloidosis:
- Initial histopathological diagnosis of amyloidosis
