What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AK104Drug

    Also called Cadonilimab

    AK104 15mg/kg intravenously(IV) every 3 weeks (Q3W), until progressive disease, unacceptable toxicity, completion of 2 years treatment or withdrawal of consent.

  • AK104+ Paclitaxel+Cisplatin or CarboplatinDrug

    AK104 (10 mg/kg) + paclitaxel (175 mg/m2)+ cisplatin (50 mg/m2) or carboplatin (AUC 4-5) , IV, Q3W, for up to 6 cycles, followed by maintenance therapy of AK104 10 mg/kg Q3W until disease progression, intolerable toxicity, withdrawal of consent, or completion of 2 years treatment.

What is being measured

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

  1. Objective response rate (ORR) assessed by investigator.

    The ORR is defined as the proportion of subjects with confirmed CR or confirmed PR per RECIST v1.1

    Measured: Up to approximately 1 years

Secondary outcomes (8)
  1. Progression-free survival (PFS) Assessed by investigator

    The time from the first administration to the first documented progressive disease (PD) or death due to any cause, whichever occurs first

    Measured: Up to approximately 2 years

  2. Duration of Response (DOR) Assessed by investigator

    Measured from the date of partial or complete response to therapy until the disease progression per RECIST v1.1 criteria

    Measured: Up to approximately 2 years

  3. Disease control rate (DCR) Assessed by investigator

    The proportion of subjects with CR, PR, or SD (subjects achieving SD will be included in the DCR if they maintain SD for ≥6 weeks) based on RECIST

    Measured: Up to approximately 1 years

  4. Time to Response (TTR) Assessed by investigator

    The time from the first administration to the date of documented CR or PR

    Measured: Up to approximately 1 years

  5. Overall survival (OS)

    The time from the first administration to death due to any cause

    Measured: Up to approximately 2 years

  6. Adverse Events (AEs)

    Characterization of incidence, severity and abnormal clinically significant manifestation or laboratory findings.

    Measured: Up to approximately 2 years

  7. serum concentrations of AK104

    assessment of PK include serum concentrations of AK104 at different timepoints after study drug administration

    Measured: Up to approximately 2 years

  8. Antidrug antibodies (ADA) of AK104

    Proportion of subjects who develop detectable anti-drug antibodies (ADAs)

    Measured: Up to approximately 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AK104 and AK104+ Paclitaxel+Cisplatin or Carboplatin in people with Vulvar Cancer, run by Akeso at 6 sites 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 3 inclusion and 4 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 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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: Sponsor decision). 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) assessed by investigator. (time frame: Up to approximately 1 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 28 Sep 2026.
