About this study
Official title: Continuous or Intermittent Pyrotinib for HER2-positive Advanced Breast Cancer: a Prospective, Randomized, Controlled, Multicentre Clinical Trial
This is a prospective, randomised, controlled, multicentre study to evaluate the efficacy and safety of continuous versus intermittent pyrotinib therapy in patients with human epidermal growth factor receptor (HER2)-positive advanced breast cancer.
- Conditions
- Advanced Breast Cancer
- Being tested
- Pyrotinib
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PyrotinibDrug
anti-HER2 tyrosine kinase inhibitor
| Study group | Role | What they receive |
|---|---|---|
| Intermittent pyrotinib | Experimental | Intermittent use of pyrotinib, 14 days on and 7 days of, every 21 days Receives: Drug: Pyrotinib |
| Continuous pyroitnib | Active comparator | oral pyrotinib qd Receives: Drug: Pyrotinib |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall response rate (ORR)
ORR is the percentage of subjects with complete remission (CR) or partial remission (PR) as the best response during the period from the beginning of the treatment to the progression of the disease or the completion of therapy (CR+PR)/Analysis of the total number of people. Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) was used to assess the objective tumor response.
Measured: From the date of starting pyrotinib to the date of confirmed CR or PR (up to approximately 1 years)
Secondary outcomes (2)
Progression-Free Survival (PFS)
PFS is defined as the time from the date of starting maintenance therapy to the date of disease progression or death from any cause, whichever occurs first.
Measured: From the date of starting pyrotinib to the date of first documentation of disease progression or death from any cause (up to approximately 1 year)
Adverse events
Adverse events during maintenance therapy will be assessed according to the NCI CTCAE v5.0.
Measured: From the date of starting pyrotinib to the end of the treatment (up to approximately 1 year)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Pyrotinib in people with Advanced Breast Cancer, run by Wenjin Yin 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 7 inclusion and 2 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 18 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 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 Wenjin Yin, M.D. (86(21)68385569, yinwenjin@renji.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall response rate (ORR) (time frame: From the date of starting pyrotinib to the date of confirmed CR or PR (up to approximately 1 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 18 Nov 2025.
