What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part 1 and Part 2: Number of Participants with Adverse Events (AEs) by Severity

    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 of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) will be graded per American Society for Transplantation and Cellular Therapy (ASTCT) consensus.

    Measured: From Baseline up to approximately 24 months

  2. Part 1: Number of Participants with Dose-Limiting Toxicity (DLT)

    The DLTs are specific adverse events including high grade hematologic or non-hematologic toxicities.

    Measured: From Baseline up to 28 days

Secondary outcomes (10)
  1. Part 1 and Part 2: Serum Concentration for JNJ-89402638

  4. Part 1 and Part 2: Time to Reach Maximum Observed Serum Concentration (Tmax) of JNJ-89402638

    Tmax of JNJ-89402638 will be reported.

    Measured: Up to approximately 24 months

  5. Part 1 and Part 2: Area Under the Serum Concentration-time Curve (AUC) of JNJ-89402638

    AUC of JNJ-89402638 will be reported.

    Measured: Up to approximately 24 months

  6. Part 1 and Part 2: Number of Participants with Presence of Anti-JNJ-89402638 Antibodies

    Participants with anti-JNJ-89402638 antibodies will be reported.

    Measured: Up to approximately 24 months

  7. Part 1 and Part 2: Overall Response (OR)

    Overall response is best response of complete response (CR) or partial response (PR), assessed according to response evaluation criteria in solid tumors (RECIST) version 1.1.

    Measured: Up to approximately 24 months

  8. Part 1 and Part 2: Complete Response (CR)

    Complete response is defined as a best response of CR assessed according to RECIST version 1.1.

    Measured: Up to approximately 24 months

  9. Part 1 and Part 2: Time to Response (TTR)

    TTR is defined for participants who achieved an OR from the time of the first dose of study treatment to the first response of PR or better as assessed according to RECIST version 1.1.

    Measured: Up to approximately 24 months

  10. Part 1 and Part 2: Duration of Response (DOR)

    DOR is defined for participants who achieved an OR in the time between the date of initial documentation of first response of PR or better to the date of first documented evidence of progressive disease or death due to any cause, whichever occurs first, as assessed according to RECIST version 1.1

    Measured: Up to approximately 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing JNJ-89402638, Bevacizumab and FOLFOX in people with Colorectal Neoplasms and Gastrointestinal Neoplasms, run by Janssen Research & Development, LLC at 12 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, Spain, South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Study Contact (844-434-4210, Participate-In-This-Study1@its.jnj.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1 and Part 2: Number of Participants with Adverse Events (AEs) by Severity (time frame: From Baseline up to approximately 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
