Official title: A Study to Assess the Efficacy and Safety of Inetetamab Combined With Anti-PD-1 Monoclonal Antibody and Albumin-Bound Paclitaxel for HER2+ Metastatic Breast Cancer

This is a multi-center, prospective, interventional, single-arm clinical trial. In the study, patients with her2-positive recurrent or metastatic breast cancer who were initially treated were included. The purpose of this study is to evaluate the efficacy and safety of Inetetamab combined with anti-PD-1 monoclonal antibody and albumin-bound paclitaxel for HER2+ Metastatic Breast Cancer.

This is a multi-center, prospective, interventional, single-arm clinical trial. In the study, patients with her2-positive recurrent or metastatic breast cancer who were initially treated were included. The purpose of this study is to evaluate the efficacy and safety of Inetetamab combined with anti-PD-1 monoclonal antibody and albumin-bound paclitaxel for HER2+ Metastatic Breast Cancer.To explore a new concept of anti-HER2 monoclonal antibody combined with immunotherapy in the treatment of recurrent or metastatic breast cancer. The primary end point is progression free survival (PFS). The secondary end points are objective response rate (ORR), Clinical Benefit Rate (CBR) and safety assessment.

What is being measured

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

  1. Progression free survival (PFS)

    PFS is defined as the time from the date of the first dose until first evidence of disease progression or death based on investigator assessment using RECIST 1.1 and irRECIST.

    Measured: Assessed up to approximately 24 months

Secondary outcomes (3)
  1. Objective response rate (ORR)

    ORR is defined as the percentage of participants who have a complete response (CR) or partial response (PR) based on CT/MRI, investigator assessment using RECIST 1.1 and irRECIST.

    Measured: Assessed up to approximately 24 months

  2. Clinical benefit rate (CBR)

    CBR is defined as the percentage of evaluable participants with best objective response of confirmed complete response or partial response per RECIST 1.1 and irRECIST, or prolonged stable disease (≥ 6 months).

    Measured: Assessed up to approximately 24 months

  3. Safety assessment (AEs and SAEs)

    Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Measured: From the time of inform consent form signature until 30 days after end of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Inetetamab, Toripalimab and Albumin-Bound Paclitaxel in people with Breast Cancer, run by Chinese Academy of Medical Sciences 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 17 inclusion and 13 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 23 Mar 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 Binghe Xu, MD (010-67781331, xubinghe@medail.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression free survival (PFS) (time frame: Assessed up to approximately 24 months). 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 Mar 2022.
