What participants receive

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

  • BL-B01D1Drug

    Also called iza-bren, izalontamab brengitecan, BMS-986507

    Administration by intravenous infusion for a cycle of 3 weeks.

Study groups in NCT06787664
Study groupRoleWhat they receive
BL-B01D1ExperimentalParticipants receive BL-B01D1 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: BL-B01D1

What is being measured

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

  1. Objective response rate (ORR)

    ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.

    Measured: Up to approximately 24 months

Secondary outcomes (8)

  1. Progression-free survival (PFS)

    The PFS is defined as the time from the participant's first dose of BL-B01D1 to the first date of either disease progression or death, whichever occurs first.

    Measured: Up to approximately 24 months

  2. Disease control rate (DCR)

    The DCR is defined as the percentage of participants who has a CR, PR, or Stable Disease (SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease [PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD]).

    Measured: Up to approximately 24 months

  3. Duration of response (DOR)

    The DOR for a responder is defined as the time from the participant's initial objective response to the first date of either disease progression or death, whichever occurs first.

    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. Cmax

    Maximum serum concentration (Cmax) of BL-B01D1 will be investigated.

    Measured: Up to approximately 24 months

  6. Tmax

    Time to maximum serum concentration (Tmax) of BL-B01D1 will be investigated.

    Measured: Up to approximately 24 months

  7. Ctrough

    Ctrough is defined as the lowest serum concentration of BL-B01D1 prior to the next dose will be administered.

    Measured: Up to approximately 24 months

  8. ADA (anti-drug antibody)

    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 2 study testing BL-B01D1 in people with Chordoma, 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 12 inclusion and 22 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 13 Apr 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 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?

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?

Objective response rate (ORR) (time frame: Up to approximately 24 months). 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 NCT06787664.

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 13 Apr 2026.
