En studie av JNJ-87189401 Plus JNJ-78278343 för avancerad prostatacancer

2 november 2026 uppdaterad av: Janssen Research & Development, LLC

En fas 1-studie av JNJ-87189401 (PSMA-CD28 bispecifik antikropp) kombinerad med JNJ-78278343 (KLK2-CD3 bispecifik antikropp) för avancerad prostatacancer

The purpose of Parts 1, 2A, and 2B of the study is to determine the recommended regimen for Phase 2 (RP2Rs) of combination of JNJ-87189401 with JNJ-78278343 and the purpose of Part 2C of this study is to determine how safe the RP2R(s) of the combination of JNJ-87189401 and JNJ-78278343 is, with or without apalutamide. Part 3 of this study evaluates the safety of the triplet combination of JNJ-87189401 and JNJ-78278343 with standard of care (SOC) lutetium Lu-177 vipivotide tetraxetan. Part 4 of this study further evaluates the safety of the triplet combination of JNJ-87189401 and JNJ-78278343 with JNJ-101556143 in participants with advanced prostate cancer.

Tidsram: Up to 4 years 8 months

An AE is any untoward medical occurrence in a participant participating in a clinical study 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 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome events, which will be graded by American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. 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.
