About this study

Official title: A Randomized, Open-Label, Multicenter Phase Ⅲ Clinical Trial to Evaluate the Efficacy and Safety of HB1801 Versus Docetaxel (Taxotere®) in Patients With Advanced Breast Cancer

This is a randomized, open-label, multicenter Phase Ⅲ clinical trial designed to evaluate the efficacy and safety of HB1801 versus Taxotere® in patients with HER2-negative advanced breast cancer.

Being tested
HB1801, Docetaxel (Taxotere®)

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HB1801Drug

    HB1801, 100 mg/m² in Cycle 1, 75 mg/m² starting from Cycle 2, once every 3 weeks (Q3W), intravenous infusion over 60 minutes.

  • Docetaxel (Taxotere®)Drug

What is being measured

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

  1. Progression-free Survival (PFS)

    PFS was defined as the time from the date of randomization to the date of progressive disease (as per RECIST v1.1) or death due to any cause.

    Measured: up to approximately 2 years after the first enrollment

Secondary outcomes (6)
  1. Objective Response Rate (ORR) assessed per RECIST v1.1

    ORR per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) assessed by investigator was defined as the percentage of participants with complete response (CR) or partial response (PR).

    Measured: up to approximately 2 years after the first enrollment

  2. Duration of Response (DOR)

    DOR by investigator assessment according to RECIST 1.1 in participants with CR or PR, defined as the time from the first documented CR/PR to PD or death.

    Measured: up to approximately 2 years after the first enrollment

  3. Disease Control Rate (DCR)

    DCR by investigator assessment according to RECIST 1.1, defined as the percentage of participants with CR, PR, or stable disease (SD) lasting at least 6 weeks.

    Measured: up to approximately 2 years after the first enrollment

  4. Overall Survival (OS)

    OS was defined as the time from the date of randomization until death due to any cause regardless of whether the participant withdrew from study therapy or received another subsequent anticancer therapy.

    Measured: up to approximately 2 years after the first enrollment

  5. The incidence and severity of adverse events (AE) and severe adverse events (SAE)

    Measured: up to approximately 2 years after the first enrollment

  6. Plasma concentration of docetaxel (free and total)

    Measured: After completion of infusion administration on Day 1 of Cycle 1

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing HB1801 and Docetaxel (Taxotere®) in people with HER2-Negative Advanced Breast Cancer, run by CSPC ZhongQi Pharmaceutical Technology Co., Ltd..

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 18 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: opening soon, as of the sponsor's last update on 4 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

Contact Clinical Trials Information Group Officer (86-0311-69085587, ctr-contact@cspc.cn), 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 approximately 2 years after the first enrollment). 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 4 Sep 2026.
