Study groups in NCT06382142
Study groupRoleWhat they receive
BL-B01D1ExperimentalParticipants receive BL-B01D1 as intravenous infusion for the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.
Receives: Drug: BL-B01D1
Eribulin or Vinorelbine or Gemcitabine or CapecitabineExperimentalParticipants receive Eribulin or Vinorelbine or Gemcitabine or Capecitabine in the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.
Receives: Drug: Eribulin; Drug: Vinorelbine; Drug: Gemcitabine; Drug: Capecitabine

What is being measured

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

  1. Progression-free survival (PFS)

    Progression-free survival (PFS) as assessed by BIRC is defined as the time between the date subjects are randomized and the first observation of disease progression (based on BICR's image-based assessment) or death.

    Measured: Up to approximately 24 months

  2. Overall survival (OS)

    Overall survival (OS) is defined as the time between the subject's randomization date and subject's death.

    Measured: Up to approximately 24 months

Secondary outcomes (5)

  1. Objective Response Rate (ORR)

    Objective response rate (ORR) is defined as the number of CR and PR in the treatment and control groups divided by the number of that group in the full analysis set (FAS).

    Measured: Up to approximately 24 months

  2. Disease Control Rate (DCR)

    Disease Control Rate (DCR) : Percentage of all randomized subjects who rated the best overall response (BOR) as complete response (CR), partial response (PR), and disease stabilization (SD) according to RECIST 1.1 criteria.

    Measured: Up to approximately 24 months

  3. Duration of Response (DOR)

    Duration of Response (DOR) : defined as the period from the date when tumor response is first recorded to the date when objective tumor progression is first recorded or the date of death.

    Measured: Up to approximately 24 months

  4. Treatment Emergent Adverse Event (TEAE)

    TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of BL-B01D1. The type, frequency and severity of TEAE will be evaluated during the treatment of BL-B01D1.

    Measured: Up to approximately 24 months

  5. Anti-drug antibody (ADA)

    Frequency of anti-BL-B01D1 antibody (ADA) will be investigated.

    Measured: Up to approximately 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing BL-B01D1, Eribulin and Vinorelbine in people with Triple-Negative Breast Cancer, run by Sichuan Baili Pharmaceutical Co., Ltd. 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 17 inclusion and 28 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: under way, not looking for participants, as of the sponsor's last update on 23 Jul 2026. 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 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival (PFS) (time frame: Up to approximately 24 months). 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 NCT06382142.

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 23 Jul 2026.
