About this study

Official title: A Single-arm, Open-label, Multicenter, Phase II Study of AK104, a PD-1/CTLA-4 Bispecific Antibody, in Subjects With Locally Advanced Unresectable or Metastatic Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Solid Tumors

It is a single-arm, open-label, multicenter, phase II study to evaluate the safety, efficacy, pharmacokinetics (PK) and immunogenicity of AK104 as a single agent in subjects with previously-treated locally advanced unresectable or metastatic MSI-H or dMMR solid tumors.

What is being measured

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

  1. Objective response rate (ORR)

    ORR is defined as the proportion of subjects with confirmed CR or PR, based on RECIST v1.1.

    Measured: Up to 2 years

Secondary outcomes (7)
  1. Disease control rate (DCR)

    DCR is defined as the proportion of subjects with confirmed CR, PR, or SD, based on RECIST v1.1

    Measured: Up to 2 years

  2. Duration of response (DoR)

    DoR is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

    Measured: Up to 2 years

  3. Progression-free survival (PFS)

    PFS is defined as the time from the start of treatment with AK104 until the first documentation of disease progression or death due to any cause, whichever occurs first.

    Measured: Up to 2 years

  4. Overall survival (OS)

    OS is defined as the time from the start of treatment with AK104 until death due to any cause.

    Measured: Up to 2 years

  5. Adverse events (AEs)

    Incidences of treatment-emergent adverse events (TEAEs) , treatment-related adverse events (TRAEs) as assessed by CTCAE v5.0

    Measured: From first dose of AK104 through to 90 days after last dose of AK104

  6. Observed pharmacokinetics (PK) exposure of AK104

    The endpoints for assessment of PK of AK104 include serum concentrations of AK104 at different timepoints after AK104 administration.

    Measured: From first dose of AK104 through to 90 days after last dose of AK104

  7. Number of subjects who develop detectable anti-drug antibodies (ADAs)

    The immunogenicity of AK104 will be assessed by summarizing the number of subjects who develop detectable ADAs.

    Measured: From first dose of AK104 through to 90 days after last dose of AK104

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AK104 in people with MSI-H/dMMR Solid Tumor, run by Akeso at 1 site in China.

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 10 inclusion and 18 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: stopped early, as of the sponsor's last update on 19 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in 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?

The study was stopped early (reason given: Due to difficuty of erollment and consideration of clinical guideline,The sponsor decided to stop study.). Results are not available in the source record.

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 rate (ORR) (time frame: Up to 2 years). 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 19 Oct 2022.
