Outcomes

Primary Outcome Measures

Phase 1b: Number of Participants with Adverse Events

An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Phase 1b: Number of Participants with Adverse Events by Severity

An assessment of severity grade will be made according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), with the exception of cytokine release syndrome (CRS), and immune effector cell-associated neurotoxicity syndrome (ICANS). CRS and ICANS should be evaluated according to the American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading.

Phase 2: Overall Response Rate (ORR)

The ORR is defined as the proportion of participants who achieve partial response (PR) or better according to International Myeloma Working Group (IMWG) criteria as assessed by the Independent Review Committee (IRC).

Secondary Outcome Measures

Phase 2: Number of Participants with Adverse Events

Levels of B-Cell Maturation Antigen (BCMA) Expressing Cells and Soluble BCMA

Levels of expression of BCMA-expressing plasma cells in the bone marrow as well as the level of soluble BCMA in blood will be reported.

Systemic Cytokine Concentrations

Serum cytokine concentrations (Interleukin [IL]-6, IL-15, IL-10, and Interferon [IFN-g]) will be measured for biomarker assessment.

Levels of CAR-T Cells

CAR-T cells markers including, but not limited to, CD4+, CD8+, CD25+, central memory, effector memory cells will be reported. An evaluation of cell populations may be performed by flow cytometry or cytometry by time of flight (CyTOF) or both and correlated with response.

Level of JNJ-68284528 T Cell Expansion (proliferation), and Persistence

Levels of JNJ-68284528 T cell expansion (proliferation), and persistence via monitoring CAR-T positive cell counts and CAR transgene level will be reported.

Number of Participants with Anti-JNJ-68284528 Antibodies

Number of participants exhibiting anti-drug antibodies for JNJ-68284528 will be reported.

Very Good Partial Response (VGPR) or Better Rate

The VGPR or better rate (stringent complete responses [sCR]+ complete response [CR]+VGPR), defined as the percentage of participants achieving VGPR or better response according to IMWG criteria during or after the study treatment. IMWG criteria for VGPR: Serum and urine M-component detectable by immunofixation but not on electrophoresis, or greater than equal to (>=) 90 percent (%) reduction in serum M-protein plus urine M-protein less than (<) 100 milligram (mg)/24 hours, CR: Negative immunofixation on the serum and urine, disappearance of any soft tissue plasmacytomas and <5% plasma cells (PCs) in bone marrow. sCR: CR plus normal free light chain (FLC) ratio, and absence of clonal PCs by immunohistochemistry (IHC), immunofluorescencea or 2- to 4 color flow cytometry.

Percentage of Participants who Achieve Clinical Benefit Rate

Clinical benefit rate is the CR + VGPR + PR + minimal response [MR] based on IMWG defined response criteria.

Duration of Response (DOR)

DOR will be calculated among responders (with a PR or better response) from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the IMWG criteria.

Progression-free Survival (PFS)

PFS defined as time from date of initial infusion of JNJ-68284528 to date of first documented disease progression, or death due to any cause, whichever occurs first. IMWG criteria for PD: Increase of 25% from lowest response value in anyone of following: Serum M-component (absolute increase must be >=0.5 gram per deciliter (g/dL), Urine M-component (absolute increase must be >=200 mg/24 hours), Participants without measurable serum and urine M-protein levels: difference between involved and uninvolved FLC levels (absolute increase must be >10 milligrams per deciliter (mg/dL), participants without measurable serum and urine M-protein levels and without measurable disease by FLC levels, bone marrow PC% (absolute percentage must be >=10%), definite development of new bone lesions or soft tissue plasmacytomas or increase in size of bone lesions or tissue plasmacytomas.

Overall Survival (OS)

OS is measured from the date of the initial infusion of JNJ-68284528 to the date of the participant's death.

Percentage of Participants With Negative Minimal Residual Disease (MRD)

MRD negative rate is defined as the proportion of participants who achieve MRD negative status by the respective time point. MRD negativity will be evaluated as a potential surrogate for PFS and OS in multiple myeloma treatment.

Time to Response (TTR)

TTR is defined as the time between date of the initial infusion of JNJ-68284528 and the first efficacy evaluation that the participant has met all criteria for PR or better.

Change from Baseline in Health-related Quality of Life (HRQoL) as Measured by EORTC QLQ-C30

HRQoL will be assessed by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30) items. Subscale and single item scores are reported on a 0-100 scale with higher scores representing better global health status, better functioning, and worst symptoms.

Change from Baseline in HRQoL as Measured by EORTC QLQ-MY20

HRQoL will be assessed by the EORTC QLQ-Multiple Myeloma ((MY20) module items. Subscale and single item scores are reported on a 0-100 scale with higher scores representing better global health status, better functioning, and worst symptoms.

Change from Baseline in Participant-reported Health Status Measured by EQ-5D-5L

Participant-reported health status measured by the EuroQol Group 5-dimension, 5-level (EQ-5D-5L) questionnaire. A total utility score is reported based on the health status, ranging from 0 to 1, where higher values indicate better health utility. The visual analog scale ranges from 0 to 100 where higher values indicate better overall health status.

Change from Baseline in Global Health Status Using PGIC Scale

Global health status as measured by the Patient Global Impression of Change (PGIC) scale in overall health. The PGIC is a single verbal rating scale ranging from 1 = a lot better now to 7 = a lot worse now.

Change from Baseline in Pain Measured by PGIS Scale

Participant reported pain measured by Patient Global Impression of Severity (PGIS) Scale. The PGIS is a single item to assess pain severity. The 5-point verbal rating scale ranged from 1 (none) to 5 (very severe).

5. Study Description

Brief Summary

The purpose of the study is to characterize safety of JNJ-68284528 and establish the recommended Phase 2 dose (RP2D) (Phase 1b) and to evaluate the efficacy of JNJ-68284528 (Phase 2).

Detailed Description

This study will evaluate the safety and efficacy of JNJ-68284528. The study will include two phases. In Phase1b the study will enroll adults with multiple myeloma with interval assessments for potential dose escalation or de-escalation in subsequent participants. The dose selected at the completion of phase 1b will be used in Phase 2. Following consent, enrolled participants will undergo an apheresis procedure to collect cells for manufacture of investigational drug product (JNJ-68284528). Following manufacture of the drug product, participants will undergo lymphodepletion prior to infusion of JNJ-68284528. Participants will be followed for at least 2 years after study drug infusion, with long-term 15 year follow-up on a separate study. The study will evaluate safety, biomarkers, pharmacokinetic/pharmacodynamic evaluations and efficacy.
