Overview
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).

- •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

- •Measurable disease at screening defined by at least 1 of the following: serum involved free light chain (iFLC) \>=50 mg/L or difference between involved and uninvolved free light chains (dFLC) \>=50 mg/L, or serum m-protein \>= 0.5 g/dL
- •One or more organs impacted by systemic AL amyloidosis
Exclusion Criteria
- •For participants with relapsed or refractory multiple myeloma:
- •Central Nervous System (CNS) involvement or clinical signs of meningeal involvement of multiple myeloma. If either is suspected, brain magnetic resonance imaging (MRI) and lumbar cytology are required
- •Active plasma cell leukemia, Waldenstrom's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes), or primary light chain amyloidosis
- •Received a cumulative dose of corticosteroids equivalent to greater than (\>) 140 mg of prednisone within the 14-day period before the start of study treatment administration

- •Live, attenuated vaccine within 4 weeks before the first dose of study treatment
- •Non-hematologic toxicity from prior anticancer therapy that has not resolved to baseline levels or to Grade less than or equal to (\<=) 1 (except alopecia, tissue post-RT fibrosis \[any grade\] or peripheral neuropathy to Grade \<=3)
- •The following medical conditions: pulmonary compromise requiring supplemental oxygen use to maintain adequate oxygenation, human immunodeficiency (HIV) infection, active hepatitis B or C infection, stroke or seizure within 6 months prior to first dose of study treatment, autoimmune disease, serious active viral or bacterial infection, uncontrolled systemic fungal infection, cardiac conditions (myocardial infarction \<=6 months prior to enrollment, New York Heart Association stage III or IV congestive heart failure, et cetera)
- •Part 2C: have progressive disease or refractory disease per IMWG after CAR-T administration
Arms & Interventions
Part 1: Dose Escalation
Participants will receive JNJ-79635322. The dose will be escalated sequentially until the recommended phase 2 dose (RP2D) regimen(s) have been identified.
Intervention: JNJ-79635322
Part 2: Dose Expansion
Participants will receive JNJ-79635322 at the RP2D regimen(s) determined in Part 1.
Intervention: JNJ-79635322
Outcomes
Primary Outcomes
Part 2: Number of Participants with Abnormalities in Laboratory Values
Time Frame: Up to 2 Years 5 months
Number of participants with abnormalities in laboratory values (hematology and chemistry) will be reported.
Parts 1 and 2: Number of Participants with Adverse Events (AEs) by Severity
Time Frame: Up to 2 years 5 months
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.
Part 1: Number of Participants with Dose-limiting Toxicity (DLT)
Time Frame: Up to 2 years 5 months
DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.
