Testing JNJ-89402638 for advanced colorectal cancer

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify the recommended phase 2 doses of JNJ-89402638 and evaluate its safety in patients with unresectable metastatic colorectal cancer. Participants must have a confirmed diagnosis of colorectal adenocarcinoma that has progressed after at least two prior treatments. The study will assess the drug's effects on measurable disease using established response criteria. The research is designed to provide insights into the dosing and safety profile of this new treatment option.

Who can join: the full rules

Inclusion Criteria:

* For Part 1 (dose escalation), Part 2 (Arm A \[JNJ-89402638 monotherapy\]): Have histologically or cytologically confirmed diagnosis of colorectal adenocarcinoma (CRC) progressing after 2 or more prior lines of standard therapy in the metastatic/unresectable setting; For Part 2 Arm B (JNJ-89402638 + bevacizumab or biosimilar): Have histologically or cytologically confirmed diagnosis of CRC progressing after 2 or more prior lines of standard therapy in the metastatic/unresectable setting; For Part 2 Arm C (JNJ-89402638 + FOLFOX/bevacizumab or biosimilar): Have histologically or cytologically confirmed diagnosis of microsatellite stable (MSS) or proficient mismatch repair (pMMR) CRC progressing after 1 or more prior lines of standard therapy in the metastatic/unresectable setting. Participants must have previously received a fluoropyrimidine and irinotecan doublet (such as FOLFIRI); For Part 2 Arm D (JNJ-89402638 + FOLFIRI/bevacizumab or biosimilar): Have histologically or cytologically confirmed diagnosis of MSS or pMMR CRC progressing after 1 prior line of standard therapy in the metastatic/unresectable setting. Must not have received irinotecan previously for metastatic disease; For Part 2 Arm E (JNJ-89402638 monotherapy in mGAC): Have histologically or cytologically confirmed diagnosis of gastric adenocarcinoma or gastroesophageal junction adenocarcinoma progressing after 1 or more prior lines of standard therapy in the metastatic/unresectable setting
* Have evaluable or measurable disease per response evaluation criteria in solid tumors (RECIST) version 1.1

  1. Part 1: Must have either measurable or evaluable disease
  2. Part 2: Must have at least 1 measurable lesion
* Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
* Have an estimated or measured glomerular filtration rate (GFR) greater than or equal to (\>=) 30 milliliter per minute (mL/min) based on modification of diet in renal disease (MDRD) 4-variable formula

Exclusion Criteria:

* Active (new or progressive) brain metastases, leptomeningeal disease, or untreated spinal cord compression
* Toxicity from prior anticancer therapy that has not resolved to Grade less than or equal to (\<=)1 (except alopecia, vitiligo, Grade \<= 2 peripheral neuropathy, or endocrinopathies that are stable on hormone replacement). For Part 2 Arm C: Grade 2 or higher peripheral neuropathy is considered exclusionary
* Has a prior or concurrent second malignancy (other than the disease under study) unless natural history or treatment is unlikely to interfere with any study endpoints of safety or the efficacy of the study treatment
* Received glucocorticoids (doses \>10 mg/day prednisone or equivalent) within 7 days prior to the first dose of study drug
* Received or plans to receive any live, attenuated vaccine within 4 weeks before the first dose of study treatment or within 4 weeks after the last dose of study treatment
