What is being measured

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

  1. Objective response rates (ORR)

    ORR is the proportion of subjects with complete response(CR) or partial response(PR) , based on RECIST v1.1

    Measured: Up to approximately 2 years

  2. Number of participants with adverse events (AEs)

    An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.

    Measured: Up to approximately 2 years

Secondary outcomes (6)
  1. Disease control rate (DCR)

    Disease control rate (DCR) is defined as the proportion of subjects with CR, PR, or stable disease(SD) based on RECIST V1.1

    Measured: Up to approximately 2 years

  2. Duration of response (DOR)

    DOR is defined for participants who had an objective response as the time from the first occurrence of a documented confirmed response (CR or PR) to the date of disease progression per RECIST v1.1 or death from any cause,whichever occurred first

    Measured: Up to approximately 2 years

  3. Time to response (TTR)

    TTR is defined for participants who had an objective response as the time from the start of treatment to the first occurrence of a documented unconfirmed response (CR or PR) .

    Measured: Up to approximately 2 years

  4. Progression-free survival (PFS)

    PFS is defined as the time from the start of treatment till the first documentation of disease progression (per RECIST v1.1 criteria) assessed by the investigator or death due to any cause (whichever occurs first).

    Measured: Up to approximately 2 years

  5. Progression-free survival 2 (PFS2)

    PFS 2 is defined as the time from the start of treatment till the second documentation of disease progression (per RECIST v1.1 criteria) assessed by the investigator or death due to any cause (whichever occurs first).

    Measured: Up to approximately 2 years

  6. Overall survival (OS)

    Overall survival is defined as the time from the start of treatment until death due to any cause.

    Measured: Up to approximately 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AK112, AK117 and Oxaliplatin in people with Metastatic Colorectal Cancer, run by Akeso at 4 sites in 2 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 8 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: under way, not looking for participants, as of the sponsor's last update on 14 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, China. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Objective response rates (ORR) (time frame: Up to approximately 2 years). 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 14 Oct 2025.
