About this study

Official title: Docetaxel Plus Atezolizumab Plus Herceptin SC and Pertuzumab (TAHP) for Patients With HER2-positive Early Breast Cancer and Subsequent Atezolizumab Plus Herceptin SC and Pertuzumab (AHP) Adjuvant tHerapy After Surgery

This study was phase IB-II clinical trial that designed to evaluate the efficacy and safety of docetaxel + atezolizumab + Herceptin sc plus pertuzumab(TAHP) plus adjuvant therapy of atezolizumab + trastuzumab + pertuzumab(AHP) after surgery in female patients with HER2-positive early breast cancer.

Adjuvant AHP (atezolizumab + Herceptin SC + pertuzumab) will be continued for remaining 1 year.

For non-p CR patients, they are going to treat with 4 cycles of AC rather than Taxane only before AHP adjuvant therapy.

What is being measured

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

  1. Pathologic CR(pCR) rate of neo-adjuvant chemotherapy

    pCR rate of neoadjuvant chemotherapy with the patients with HER2+ EBC

    Measured: Pathologic Clinical response is perforemed after end of cycle 6 (each cycle is 21days).

Secondary outcomes (1)
  1. Event free survival(EFS)

    Event free survival of the patient with pCR vs. non-pCR

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TAHP and AHP and TAHP plus AC and AHP in people with HER2-positive Breast Cancer, run by Samsung Medical Center at 1 site in South Korea.

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 13 inclusion and 22 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 21 Mar 2019. 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 South Korea. 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?

Results are not available in the source record.

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

Contact Yeon-hee Park, MD,PhD (2-3410-3459 ext. 82, yeonh.park@samsung.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathologic CR(pCR) rate of neo-adjuvant chemotherapy (time frame: Pathologic Clinical response is perforemed after end of cycle 6 (each cycle is 21days).). 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 NCT03881878, which also lists 1 linked publication.

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 21 Mar 2019.
