Trial Parameters
Brief Summary
The purpose of this study is to identify the recommended phase 2 regimen(s) RP2R(s) of JNJ-78278343 and combination agent in Part 1 (dose escalation) and to determine safety at the putative RP2R(s) of JNJ-78278343 with the combination agent in Part 2 (dose expansion).
