    RO7122290 will be administered using a QW (Part I) or Q3W (Part I or Part II) schedule in combination with 100 mg cibisatamab Q3W with obinutuzumab pre-treatment. The maximum dose of RO7122290 to be explored in combination with cibisatamab with obinutuzumab pre-treatment in this study is 500 mg for the QW dosing interval (Part I) or 1500 mg for the Q3W dosing interval (Part I or Part II).

  • CibisatamabDrug

    Cibisatamab will be administered to participants at a fixed dose of 100 mg Q3W (100 mg on Day 1 of each 21-day cycle).

  • ObinutuzumabDrug

    Obinutuzumab will be administered (IV) as pre-treatment on Day - 8/- 7 (split dose) or

    • 8 (single dose) prior to C1D1 of cibisatamab and as re-treatment every 6 months if the participant is still receiving cibisatamab

What is being measured

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

  1. Part I: Occurrence of dose-limiting toxicities

    The DLT observation period is defined as a period of 21 days after the first administration of RO7122290 combined with cibisatamab. Additional days (maximum 3 days per dosing) are allowed in case of treatment delays for non-safety reasons.

    Participants are evaluable for DLT assessment, if they have received one dose of cibisatamab and at least two doses of RO7122290 during the DLT period.

    Measured: Baseline up to 21 days

  2. Percentage of Participants with Adverse Events

    Incidence, nature, and severity of adverse events (AEs) graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5 with the exception of cytokine release syndrome (CRS), which is graded according to the ASTCT grading scale for CRS (with individual signs and symptoms of CRS graded separately using the CTCAE v5.0 grading scale)

  37. Objective response rate (ORR) defined as complete response (CR) + partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    Objective response rate (ORR) is determined as the rate of participants with an objective tumor response of CR or PR. ORR will be derived for RECIST Version 1.1 and will be based on Investigators' assessment.

    Measured: Baseline up to 28 months

  38. Disease control rate (DCR); defined as response rate (RR) + stable disease (SD) according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    Disease control rate (DCR) is determined as the rate of participants with an objective tumor response of CR, PR or SD. DCR will be derived for RECIST Version 1.1 and will be based on Investigators' assessment.

    Measured: Baseline up to 28 months

  39. Duration of response (DoR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    DoR will be calculated for participants who have a best overall response of CR or PR and will be defined as the time from first occurrence of a documented OR until the time of documented disease progression or death (death within 30 days from last study treatment) from any cause, whichever occurs first. Censoring

    Measured: Baseline up to 28 months

  40. Progression-free survival (PFS) according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

For participants who do not have documented progressive disease or death (within 30 days from last study treatment) during the study, PFS will be censored at the day of the last tumor assessment. Participants without any post-baseline assessments or with all post-baseline assessments having unknown result/response but known to be alive at the clinical cut off for the analysis will be censored at the date of study treatment initiation plus one day.

    Measured: Baseline up to 28 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing RO7122290, Cibisatamab and Obinutuzumab in people with Metastatic Colorectal Cancer, run by Hoffmann-La Roche at 13 sites in 5 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 12 inclusion and 40 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: finished, as of the sponsor's last update on 14 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Spain, South Korea, United Kingdom, Denmark, Netherlands. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part I: Occurrence of dose-limiting toxicities (time frame: Baseline up to 21 days). 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?

On the ClinicalTrials.gov record for NCT04826003, which also lists 1 linked publication.

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 14 Jul 2025.
