About this study
Official title: An Open-label, Prospective Study of Tumor Response Time of Palbociclib in Combination With AI in Real-world First-line Treatment of Postmenopausal Chinese Patients With ER (+) HER2 (-) Metastatic Breast Cancer
The international treatment guidelines now include recommendations for the use of CDK 4/6 inhibitors in combination with hormone agents for the treatment of postmenopausal women with hormone-receptor-positive/HER2-negative ABC as the first-line standard therapy in endocrine sensitive patients.
Nevertheless, it is generally thought that chemotherapy is associated with greater and earlier tumor response, especially in case of high burden of disease. In a retrospective analysis of real-world clinical practice (2002-2012) from US, only 60% of patients initiated ET as the first treatment following metastatic diagnosis . In the real-life world of China, a large number of HR+/HER2- ABC patients with non-visceral crisis also received chemotherapy in first-line treatment, even though the ORR is similar compared with CDK4/6 inhibitors with endocrine therapy. Zhejiang Cancer Hospital retrospective analysis of 5 cases of advanced breast cancer first-line use of Ibance + ET, they were evaluated within 50 days (from 27days to 50days).
Based on the early response time observed in real-world data mentioned above, it is proposed a prospective study to further observe the tumor reduction rate in real-world, including to identify the time of patient symptom improvement according to the quality of life scale.
Read the detailed description
According to the early assessment(4 weeks) , this prospective study comprehensively investigate TTR of Palbociclib+ET in the first line treatment for HR+/HER2- MBC patients in China real-world study.
Furthermore, evaluate the Early Tumor Shrinkage(ETS) of Palbociclib + ET, and assess Treatment Free Interval (TFI) with TTR and ETS；TFI was analyzed at the following time points: ≤24, >24, ≤36, > 36, ≤48, >48 months.
Accroding to the follow-up of QoL questionnaire, understand the clinical symptoms improvements time.
Meanwhile, cooperation with radiology department, establish a model for predicting early response by observing the imaging and clinical pathological characteristics of patients with ETS.

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The international treatment guidelines now include recommendations for the use of CDK 4/6 inhibitors in combination with hormone agents for the treatment of postmenopausal women with hormone-receptor-positive/HER2-negative ABC as the first-line standard therapy in endocrine sensitive patients.
Nevertheless, it is generally thought that chemotherapy is associated with greater and earlier tumor response, especially in case of high burden of disease. In a retrospective analysis of real-world clinical practice (2002-2012) from US, only 60% of patients initiated ET as the first treatment following metastatic diagnosis . In the real-life world of China, a large number of HR+/HER2- ABC patients with non-visceral crisis also received chemotherapy in first-line treatment, even though the ORR is similar compared with CDK4/6 inhibitors with endocrine therapy. Zhejiang Cancer Hospital retrospective analysis of 5 cases of advanced breast cancer first-line use of Ibance + ET, they were evaluated within 50 days (from 27days to 50days).
Based on the early response time observed in real-world data mentioned above, it is proposed a prospective study to further observe the tumor reduction rate in real-world, including to identify the time of patient symptom improvement according to the quality of life scale.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Palbociclib and AI in people with Breast Neoplasms, run by Zhejiang Cancer 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 8 inclusion and 9 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 15 Jul 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 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Wen-Ming Cao, Ph.D., M.D. (8613858064001, caowm@zjcc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Early Tumor Shrinkage (ETS) (time frame: 4 weeks, 8weeks). The study lists 2 primary outcomes in all. 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 NCT04858997, which also lists 9 linked publications.
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 15 Jul 2021.
