OncoMatch/Clinical Trials/NCT06663319
A Study of JNJ-89402638 for Metastatic Colorectal and Gastric Cancers
Is NCT06663319 recruiting? Yes, currently enrolling (May 2026). This Phase 1 trial studies multiple treatments including JNJ-89402638 and Bevacizumab for colorectal neoplasms.
Treatment: JNJ-89402638 · Bevacizumab · FOLFOX · FOLFIRI — The purpose of this study is to determine the putative recommended phase 2 dose(s) (RP2Ds) of JNJ-89402638 and to determine the safety of JNJ-89402638 at the RP2D(s) in participants with metastatic colorectal cancer (mCRC) and metastatic gastric cancer (mGAC) and to determine the safety and tolerability of JNJ-89402638 in combination with bevacizumab or biosimilar with or without chemotherapy in participants with mCRC.
