About this study

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.

  30. Phase 2: Patient Global Impression of Change (PGIC) Score at Days 28, 56, 78, 100

    Time frame: Days 28, 56, 78, 100

    PGIC was a single item to assess the participant's perception in change of their overall health status using a 7-point verbal rating scale ranging from 1(a lot better now) to 7 (a lot verse now), where 1: a lot better now; 2: moderately better now; 3: a little better now; 4: neither better nor worse; 5: a little worse now; 6: moderately worse now; 7: a lot worse now. Higher score indicated worse health status.

  31. Phase 2 (US Population): Change From Baseline in EORTC QLQ-MY20 at Days 7, 28, 56, 78, 100, 128, 156, 184, 212, 240, 268, 296, 324, 352 and 380

    Time frame: Baseline, Days 7, 28, 56, 78, 100, 128, 156, 184, 212, 240, 268, 296, 324, 352 and 380

    EORTC QLQ-MY20 scale comprised of 20 questions that addressed four myeloma-specific HRQoL domains: disease symptoms (includes bone aches or pain, back pain, hip pain, arm or shoulder pain, chest pain, and pain increasing with activity), side effects of treatment (includes drowsiness, thirst, feeling ill, dry mouth, hair loss, upset by hair loss, tingling hands or feet, restlessness/agitation, acid indigestion/heartburn, and burning or sore eyes), future perspective (includes worry about death and health in the future, and thinking about illness) and body image. The scale was administered to assess 4 single items: feel restless or agitated, thinking about your illness, worried about dying, worried about health in the future. Scores were averaged and scales were transformed on a 0 to 100 scale. A high score for side effects of treatment represented a high level of symptomatology or problems, whereas a high score for future perspective represented better outcomes.

    Time frame: Baseline, Days 7, 28, 56, 78, 100, 128, 156, 184, 212, 240, 268, 296 and 324
