About this study

Official title: Neoadjuvant Therapy Study Guided by Drug Screening in Vitro Patient-derived Tumor-like Cell Clusters for HER2 Positive Early Breast Cancer Patients

Neoadjuvant treatment is an important treatment for early breast cancer patients. Patients with her2 enriched subtype who achieved pCR after neoadjuvant treatment would have longer survival. The neoadjuvant treatment for her2 positive patients include chemotherapy and targeted therapy. Although the pCR rate was high to 60% after use of trastuzumab and pertuzumab, but the adverse reaction of combined chemotherapy could not be negligible. Some studies have attempted chemotherapy-free treatment for her2 positive patients during neoadjuvant therapy. But, which patient could be exempted from chemotherapy and which drug could be omitted are still unknow before treatment. Drug sensitivity screening in vitro was a promising method for choosing chemotherapy. But there was no method could select effective drugs accurately for breast cancer patients until now.

Previously, investigators developed a patient-derived tumor-like cell clusters in vitro culture technology. Feasibility for guiding clinical treatment by drug sensitivity screening based on this technology have been explored by preliminary exploration with a well corresponding. And the results have been published. This study will explore whether drug screening in vitro patient-derived tumor-like cell clusters from breast cancer tissue could be a metheod for omitting chemotherapy for her2 positive participants.

Read the detailed description

Neoadjuvant chemotherapy for breast cancer could make unresectable breast cancer be resectable and improve breast conservation rate. Patients with her2 enriched subtype who achieved pCR after neoadjuvant treatment would have longer survival. The neoadjuvant treatment for her2 positive patients include chemotherapy and targeted therapy. Although the pCR rate was high to 60% after use of trastuzumab and pertuzumab, but the adverse reaction of combined chemotherapy could not be negligible. Based on the application of dual targeted drugs, some studies have attempted chemotherapy-free treatment for her2 positive patients during neoadjuvant therapy. But, which patient could be exempted from chemotherapy and which drug could be omitted are still unknow before treatment. Drug sensitivity screening in vitro was a promising method for choosing chemotherapy. But there was no method could select effective drugs accurately for breast cancer participants until now.

Previously, investigators developed a patient-derived tumor-like cell clusters(PTC) in vitro culture technology. It is a cell cluster including tumor cells, mesenchymal cells and lymphocytes, which simulates the tumor microenvironment in vitro. In the preliminary exploration, investigators included 35 early breast cancer participants, the corresponding between in vitro drug sensitivity screening based on this technology and clinical treatment results was well. The results have been published.

This study will focus on her2 positive early breast cancer participants. 46 participants will be included. All of them will received in vitro drug sensitivity screenning upon PTC before neoadjuvant therapy. All participants will received trastuzumab and pertuzumab. The choice of chemotherapy drugs is determined based on the PTC drug sensitivity results. If single-agent chemotherapy is effective in vitro, this drug will be the chemotherapy regimen for the corresponding participants. This study expects that the pCR rate could achieve 60% in the case of chemotherapy downgrading after in vitro drug sensitivity screening.

What is being measured

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

  1. pathological complete response(pCR)

    ypT0/is, ypN0

    Measured: up to 12 weeks

Secondary outcomes (3)
  1. event-free survival (EFS)

    The time from random assignment to disease progression, including local progression before surgery; disease recurrence-local, regional, distant, ipsilateral noninvasive, or contralateral (invasive or noninvasive)-or death from any cause

    Measured: 5 years

  2. invasive disease-free survival(IDFS)

    The time from surgery to the first documented occurrence of an event defined as ipsilateral invasive local recurrence, ipsilateral locoregional invasive recurrence, distant recurrence, contralateral invasive breast cancer, or death from any cause

    Measured: 5 years

  3. objective response rate

    complete response and partial response

    Measured: up to 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing neoadjuvant chemotherapy upon in vitro PTC drug sensitivity screenning in people with HER2-positive Early Breast Cancer, run by Peking University People's 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 4 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 1 Apr 2021. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

This study is still under way. Results are not available in the source record yet.

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

Contact Chaobin Wang (+86 010 88324010, hzwcb1990@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pathological complete response(pCR) (time frame: up to 12 weeks). 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 1 Apr 2021.
