About this study

Official title: A Single-arm, Single-center Phase II Clinical Study of Recombinant Humanized Anti-HER2 Monoclonal Antibody-AS269 Conjugate (ARX788) in the Treatment of Unresectable and/or Metastatic Breast Cancer With Low Expression of HER2

A Phase 2 Study of ARX788 in unresectable and/or metastatic breast cancer with low expression of HER2.

Read the detailed description

A single arm, phase 2 study of ARX788 in unresectable and/or metastatic breast cancer with low expression of HER2. Subjects should received ≥2 lines of systemic chemotherapy regimens for recurrent or metastatic disease, and for HR positive subjects, also need to have received ≥2-line endocrine therapy ± targeted therapy (including neoadjuvant/adjuvant therapy). HER2 low expression is defined as HER2 IHC 1+ or HER2 IHC 2+ and FISH negative. The ARX788 will be administered every 3 weeks (Q3W) intravenous (IV) infusion.

What is being measured

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

  1. Objective remission rate (ORR)

    ORR is defined as the percentage of subjects who have achieved complete response and partial response according RECIST 1.1

    Measured: 2 years

Secondary outcomes (4)
  1. Progression-free survival (PFS)

    PFS is defined as the time between date of first dose of study therapy and date of progression or death, whichever occurs first, will be computed for response evaluable subjects. Subjects will be censored at time of subsequent therapy

    Measured: 2 years

  2. Overall survival (OS)

    Overall survival (OS) is defined as the time from first dose of study therapy to the date of death (any cause). Subjects who are alive will be censored at the last known time that the subject was alive

    Measured: 2 years

  3. Disease control rate (DCR)

    Disease control rate (DCR) is defined as cases where objective remission (assessed as complete remission or partial remission according to RECIST 1.1 standard) or stable disease during the study

    Measured: 2 years

  4. Duration of relief (DOR)

    DOR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ARX788 in people with Breast Cancer With Low Expression of HER2, run by Fudan University 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 11 inclusion and 21 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 25 Apr 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?

Results are not available in the source record.

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

Contact Ting Li (+8618121299346, cinderellaliting@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective remission rate (ORR) (time frame: 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 25 Apr 2022.
