About this study

Official title: Study Comparing the Efficacy and Safety of Epirubicin Combined With Cyclophosphamide Followed by Docetaxel (EC-T) Verses Paclitaxel Combined With Carboplatin (PCb) in the Adjuvant Chemotherapy of Non-triple Negative Breast Cancer

This study is a randomized, single center, phase III clinical trial comparing the efficacy and safety of four cycles of epirubicin combined with cyclophosphamide followed by four cycles of docetaxel (EC*4-T*4) verses 6 cycles of weekly paclitaxel combined with carboplatin (PCb*6) in the adjuvant chemotherapy of non-triple negative breast cancer patients. The study is divided in to 2 branches: PANSY-1 and PANSY-2. PANSY-1 is a study of hormone receptor (HR)-positive/human epidermal growth factor receptor-2 (HER2)-negative patients with ≥4 positive lymph node, while PANSY-2 is a study of HER2-positive patients with ≥1 positive lymph node.

Read the detailed description

PANSY-1 will be comparing the efficacy and safety of four cycles of epirubicin combined with cyclophosphamide followed by four cycles of docetaxel (EC-T) verses six cycles of paclitaxel combined with carboplatin (PCb).

PANSY-2 will be comparing the efficacy and safety of four cycles of epirubicin combined with cyclophosphamide followed by four cycles of docetaxel with trastuzumab (EC-TH) verses six cycles of paclitaxel combined with carboplatin and trastuzumab (PCbH); both followed by 1 year adjuvant trastuzumab.

After pertuzumab became legally available in China, participants of PANSY-2 may choose to receive trastuzumab and pertuzumab dual targeted therapy, thus comparing the efficacy and safety of four cycles of epirubicin combined with cyclophosphamide followed by four cycles of docetaxel with trastuzumab and pertuzumab (EC-THP) verses six cycles of paclitaxel combined with carboplatin, trastuzumab and pertuzumab (PCbHP); both followed by 1 year adjuvant trastuzumab and pertuzumab.

With the inclusion of pertuzumab in China's medical insurance in January 2020, study protocols were revised to include dual targeted therapy for HER2-positive participants.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Paclitaxel, Carboplatin and Epirubicin in people with Breast Cancer, 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 15 inclusion and 15 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: under way, not looking for participants, as of the sponsor's last update on 26 Nov 2025. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

disease free survival (time frame: 5 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 26 Nov 2025.
