About this study

Official title: Gemcitabine and Oxaliplatin With or Without KN035 for Biliary Tract Cancer: a Randomised, Open-label, Parallel-group, Multicenter Phase III Study

This is a randomized, open-label, parallel-group multi-center study of Phase 3 study to assess the efficacy and safety of KN035 compared to standard of care (SOC) Gemcitabine-based chemotherapies in the treatment of participants with previously untreated locally advanced or metastatic biliary tract cancer.

The primary hypothesis of this study is that participants will have a longer overall Survival (OS) when treated with combined therapy than SOC.

Being tested
KN035 plus Gemcitabine & oxaliplatin, Gemcitabine & oxaliplatin
Medical subject headings
Biliary Tract Neoplasms

What is being measured

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

  1. Overall Survival (OS)

    was defined as the time from randomization to death due to any cause.

    Measured: Observed by 12 weeks after progressive disease or end of treatment

Secondary outcomes (5)
  1. Progression Free Survival (PFS)

    was defined as the time from randomization to documented disease progression per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) or death due to any cause, whichever occurred first and was based on blinded independent Review Committee (BIRC) review.

    Measured: Observed by 6 weeks

  2. Objective response rate (ORR)

    was defined as the percentage of participants in the analysis population who experienced a Complete Response or a Partial Response and was assessed using RECIST 1.1 based on BIRC evaluation.

    Measured: Observed by 6 weeks

  3. Disease control rate (DCR)

    was defined as the percentage of participants in the analysis population who experienced a Complete Response or a Partial Response or stable disease and was assessed using RECIST 1.1 based on BIRC evaluation

    Measured: Observed by 6 weeks

  4. Duration of Response (DOR)

    was defined as the time from the first met for complete response/partial response (whichever was first recorded) until the first date that recurrent or progressive disease was objectively documented (taking as reference for progressive disease the smallest measurements recorded on study)

    Measured: Observed by 6 weeks

  5. Time to progression (TTP)

    was defined as the time from randomization to the first date that progressive disease was objectively documented

    Measured: Observed by 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing KN035 plus Gemcitabine & oxaliplatin and Gemcitabine & oxaliplatin in people with Biliary Tract Neoplasms, run by 3D Medicines (Sichuan) Co., Ltd. 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 8 inclusion and 6 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 23 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 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Overall Survival (OS) (time frame: Observed by 12 weeks after progressive disease or end of treatment). 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 23 Sep 2026.
