A Phase 3 Randomized, Double-blind, Placebo-controlled Study of Pasritamig (JNJ-78278343), a T Cell Engaging Agent Targeting Human Kallikrein 2, With or Without JNJ-87189401, a PSMA-CD28 Costimulatory Agent, Plus Best Supportive Care Versus Best Supportive Care for Late-line Metastatic Castration-resistant Prostate Cancer
A Phase 3 Randomized, Double-blind, Placebo-controlled Study of Pasritamig (JNJ-78278343), a T Cell Engaging Agent Targeting Human Kallikrein 2, With or Without JNJ-87189401, a PSMA-CD28 Costimulatory Agent, Plus Best Supportive Care Versus Best Supportive Care for Late-line Metastatic Castration-resistant Prostate Cancer
The purpose of this study is to evaluate the overall survival (length of time from the start of study to date of death from any cause) for pasritamig (JNJ-78278343) in Part 1 in combination with best supportive care (BSC) and in Part 2 with JNJ-87189401+BSC as compared to placebo with BSC in participants with metastatic castration-resistant prostate cancer (mCRPC; a stage of cancer that has spread beyond the prostate gland and is no longer responding to hormone therapies).
Inclusion Criteria
Androgen-receptor pathway inhibitor (ARPI): Must have progressed on at least 1 ARPI and unlikely to benefit from retreatment with another ARPI
Taxanes: Required to have received at least 2 previous taxane-based regimens. If a participant has received only 1 taxane regimen, the participant is eligible if:
Radioligand therapy: Required to have been previously treated with at least 1 dose of Prostate-specific membrane antigen (PSMA)-targeted lutetium radioligand therapy (eg, lutetium Lu-177 vipivotide tetraxetan), unless one of the following applies:
Polyadenosine diphosphate-ribose polymerase inhibitors (PARPi): Required to have been previously treated with PARPi, if the participant has a known germline or somatic BRCA mutation and treatment is available
