What is being measured

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

  1. Progression-free survival(PFS)

    PFS is defined as the time from enrollment to the first imaging disease progression or death (whichever occurs first). Assessed according to RECIST v1.1 by investigator.

    Measured: Up to 3 years

Secondary outcomes (3)
  1. Objective response rate (ORR)

    ORR is defined as the proportion of patients with complete response(CR) and partial response(PR) assessed by the investigator in accordance with the RECIST 1.1 criteria.

    Measured: Up to 3 years

  2. Overall survival (OS)

    OS is defined as the time between enrollment and the patient's death due to any OS is defined as the time between enrollment and the patient's death due to any cause

    Measured: Up to 5 years

  3. Incidence of Treatment-Emergent Adverse Events

    Includes the Treatment-Emergent adverse event profile and rates according to the Common Terminology Criteria for Adverse Events version 5.0.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adebrelimab and dalpiciclib in people with Breast Cancer, run by Tongji 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 13 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: looking for participants now, as of the sponsor's last update on 15 Apr 2024. 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 Xiong huihua (027-83663405, xionghuihua@hotmail.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: Up to 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 15 Apr 2024.
