What participants receive

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression free survival(PFS)
PFS was defined as the time from the start of treatment to either the first documented disease progression or death from any cause
Measured: 3 years
Secondary outcomes (2)
Objective response rate (ORR)
ORR was defined as the proportion of patients with a complete response or a partial response
Measured: 2years
Overall survival(OS)
OS was defined as the time from the start of treatment to death from any cause
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer, run by Beijing 302 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 9 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: status not confirmed, as of the sponsor's last update on 28 Apr 2023. 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.
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 Jinmei Zhou (01066947250, jinzhu2714@sina.com), 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: 3 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 28 Apr 2023.
