About this study

Official title: An Open-label, Single-arm, Multicenter, Phase II Clinical Study of Disitamab Vedotin Plus Cadonilimab as Therapy in Patients With HER2 Mutant Advanced or Metastatic Bile Duct Adenocarcinoma

It is a single arm, open-label, phase II cinical trial to evaluate the efficacy and safety of Disitamab Vedotin Plus Cadonilimab in second-line treatment of patients with Advanced or Metastatic Bile Duct Adenocarcinoma

Read the detailed description

Biliary tract cancer is a group of highly heterogeneous and aggressive epithelial cancers, accounting for about 3% of all digestive system tumors. It is highly aggressive, and most of them are found in advanced stages, with extremely poor prognosis and a 5-year survival rate of less than 5%. The overexpression rate of HER2 in biliary tract tumors is about 26.5%, and the amplification rate is about 30.1%. In addition, HER2 mutations in biliary tract malignant tumors also include HER2 mutations. In addition, HER2 mutations in biliary malignant tumors also include HER2 mutations. Currently, anti-HER2 strategies have become a new hotspot for exploration in BTC. It is a single arm, open-label, phase II cinical trial conducted in China and plans to recruit 28 patients with HER2 Mutant Advanced or Metastatic Bile Duct Adenocarcinoma who have progressed through first-line treatment. The purpose of this study is to evaluate the efficacy and safety of second-line treatment with Disitamab Vedotin Plus Cadonilimab

What is being measured

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

  1. Objective response rate(ORR)

    The number of cases in which tumor size is reduced to PR or CR / the total number of evaluable cases (%)

    Measured: 12 months

Secondary outcomes (4)

  1. Overall survival (OS)

    The time interval between the start date of study drug and the date of death (any cause)

    Measured: [Time Frame: up to 36 months]

  2. Progression-free survival (PFS)

    Refers to the date from the date of admission to the date of the first progression of disease or death of any cause, using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

    Measured: [Time Frame: up to 12 months]

  3. Disease control rate (DCR)

    Percentage of confirmed cases including complete remission (CR), partial remission (PR) and disease stability (SD) among patients with evaluable efficacy

    Measured: [Time Frame: up to 12 months]

  4. Incidence of Treatment-Emergent 3/4 Adverse Events

    Number and percentage of participants with Adverse Events (any Grade and Grade 3/4)

    Measured: [Time Frame: up to 12 months after enrollment or study close]

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Disitamab Vedotin Plus Cadonilimab in people with Bile Duct Adenocarcinoma Non-Resectable and HER2 Gene Mutation, run by Zhejiang Cancer Hospital 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 19 inclusion and 25 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: status not confirmed, as of the sponsor's last update on 26 Apr 2024. 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?

Results are not available in the source record.

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

Contact Jieer Ying, M.D. (13858195803, jieerying@aliyun.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective response rate(ORR) (time frame: 12 months). 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 NCT06383533.

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 26 Apr 2024.
