A Phase 1, First-in-human Study of JNJ-87801493 in Combination With CD3 T-Cell Engagers in Participants With Relapsed/Refractory B-cell Non-Hodgkin Lymphoid Malignancies (NHLs)
The purpose of this study is to characterize safety and to determine the recommended phase 2 regimen (RP2R) for JNJ-87801493 in combination with T-cell engagers (TCEs) \[Part A: Dose Escalation\] and to further assess the safety of JNJ-87801493 at the RP2R in combination with TCEs \[Part B: Dose Expansion\].
• Histologic documentation of B-cell NHL. All participants in part 1 must have relapsed or refractory disease with no other approved therapies available that would be more appropriate in the investigator's judgment. In Part 2, participants with diffuse large B-cell lymphoma (DLBCL) or other high-grade B cell lymphoma and participants with transformed lymphoma from low-grade B cell malignancies who relapsed or failed to respond to only one prior systemic treatment regimen can be included
• Part 1 participants must have evaluable or measurable disease and Part 2 participants must have measurable disease; all as defined by the Lugano criteria for non-Hodgkin lymphoid malignancies (NHL) and the international workshop on Waldenstrom's Macroglobulinemia (IWWM-6) for WM
• Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
• Hematologic laboratory parameters must meet the required criterias and the values must be without a transfusion or growth factors for at least 7 days prior to the first dose of study drug
• Participants of childbearing potential must have a negative highly sensitive serum pregnancy test (beta (β)-human chorionic gonadotropin) at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study.
