What is being measured

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

  1. Phase 1a: Number of Participants Experiencing Adverse Events (AEs)

    Number of participants with treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), including dose limiting toxicities (DLTs), AEs meeting protocol-defined adverse event of clinical interest (AECI) criteria, laboratory values, and electrocardiogram results.

    Measured: Up to approximately 24 months

  2. Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-C0979 Monotherapy

    MTD or MAD, defined as the highest dose for which the estimated toxicity rate is closest to the target toxicity rate of 28%, or the highest dose administered, respectively.

    Measured: Up to approximately 10 months

  3. Phase 1a: Recommended Dose(s) for Expansion (RDFE[s])

    The potential RDFE(s) of BG-C0979 will be determined based on the totality of data including the MTD or MAD, long-term tolerability, pharmacokinetics (PK), preliminary antitumor activity, and any other relevant data, as available.

    Measured: Up to approximately 10 months

  4. Phase 1b: Recommended Phase 2 Dose (RP2D)

    RP2D of BG-C0979 alone and in combination with tislelizumab will be determined based on safety, PK, preliminary antitumor activity, and other relevant data, as available.

    Measured: Up to approximately 24 months

  5. Phase 1b: Overall Response Rate (ORR)

    ORR as determined from tumor assessment by the investigator using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. For castration-resistant prostate cancer (CRPC), ORR will be assessed by RECIST v1.1 criteria for soft tissue and Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria for bone lesions. ORR is defined as the percentage of participants with best overall response of a complete response (CR) or partial response (PR).

    Measured: Up to approximately 24 months

Secondary outcomes (12)
  1. Phase 1a: ORR

    ORR as determined from tumor assessment by the investigator using RECIST v1.1. For CRPC, ORR will be assessed by RECIST v1.1 criteria for soft tissue and PCWG3 criteria for bone lesions. ORR is defined as the percentage of participants with best overall response of a complete response (CR) or partial response (PR).

    Measured: Up to approximately 24 months

  2. Phase 1a and 1b: Duration of Response (DOR)

    DOR as determined from tumor assessment by the investigator using RECIST v1.1. For CRPC, DOR will be assessed by RECIST v1.1 criteria for soft tissue and PCWG3 criteria for bone lesions. DOR is defined as the time from the first determination of an objective response until the first documentation of disease progression or death due to any cause, whichever occurs first.

    Measured: Up to approximately 24 months

  3. Phase 1a and 1b: Disease Control Rate (DCR)

    DCR as determined from tumor assessment by the investigator using RECIST v1.1. For CRPC, DCR will be assessed by RECIST v1.1 criteria for soft tissue and PCWG3 criteria for bone lesions. DCR is defined as the percentage of participants with best overall response of a CR, PR, or stable disease.

    Measured: Up to approximately 24 months

    Measured: Up to approximately 3 months

  5. Phase 1a: Area Under the Concentration-Time Curve (AUC) for BG-C0979

    Measured: Up to approximately 3 months

  6. Phase 1a: Maximum Observed Concentration (Cmax) of BG-C0979

    Measured: Up to approximately 3 months

  7. Phase 1a: Time to Maximum Concentration (Tmax) of BG-C0979

    Measured: Up to approximately 3 months

  8. Phase 1b: Number of Participants Experiencing Adverse Events (AEs)

    Number of participants with TEAEs and SAEs, including AECIs, laboratory values, and electrocardiogram results.

    Measured: Up to approximately 24 months

  9. Phase 1b: Progression-Free Survival

    PFS is defined as the time from the date of the first administration of study drug(s) to the date of the first documentation of disease progression or death due to any cause, whichever occurs first.

    Measured: Up to approximately 24 months

  10. Phase 1b: Radiographic Progression-Free Survival (rPFS) for Participants with CRPC

    rPFS is defined as the time from the date of the first administration of study drug(s) to the date of the first objective evidence of radiographic disease progression or death due to any cause, whichever occurs first.

    Measured: Up to approximately 24 months

  11. Prostate-Specific Antigen (PSA) Response for Participants with CRPC

    PSA response is defined as a ≥50% decrease in PSA level from baseline to the lowest post-baseline PSA result, confirmed by a second consecutive PSA assessment at least 3 weeks later.

    Measured: Up to approximately 24 months

  12. Phase 1b: Plasma Concentration of BG-C0979, Alone and in Combination with Tislelizumab

    Measured: Up to approximately 3 months

Individual data sharing
Yes: BeOne shares data on completed studies responsibly and provides qualified scientific and medical researchers access to data and supporting documentation for clinical trials in dossiers for medicines and indications after submission and approval in the United States, China, and Europe. Clinical trials supporting subsequent local approvals, new indications, or combination products are eligible for sharing once corresponding regulatory approvals are achieved. BeOne shares data only when permitted by applicable data privacy and security laws and regulations, when it is feasible to do so without compromising the privacy of study participants, and other considerations. Qualified researchers with appropriate competencies who are engaged in novel scientific research may submit a request for participant-level data with a research proposal for BeOne review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.

A Phase 1 study testing BG-C0979 and Tislelizumab in people with Advanced Solid Tumor, run by BeOne Medicines at 18 sites in 4 countries.

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 6 inclusion and 3 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 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in China, United States, Australia, Spain. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Study Director (8778285568, clinicaltrials@beonemed.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1a: Number of Participants Experiencing Adverse Events (AEs) (time frame: Up to approximately 24 months). The study lists 5 primary outcomes in all. 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 28 Sep 2026.
