About this study

Official title: A Phase 2, Multicenter, Open-Label Study of Tislelizumab (BGB-A317) in Patients With Relapsed or Refractory Classical Hodgkin Lymphoma

This was a Phase 2 trial evaluating the effectiveness and safety of tislelizumab in participants with relapsed or hard-to-treat classical Hodgkin lymphoma (cHL). Participants were grouped by prior treatments. The main outcome was to assess overall response rate (ORR) across both cohorts. Participants continued receiving the study treatment until their disease got worse, side effects became too severe, or they chose to stop for other reasons.

What is being measured

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

  1. Overall Response Rate (ORR)

    ORR was defined as the percentage of participants who achieved a best overall response of complete response (CR) or partial response (PR) by Positron Emission Tomography (PET) and Computed Tomography (CT) per the Lugano Classification and as determined by the investigator. CR was defined as the complete disappearance of all target lesions on PET-CT, with no new lesions detected. PR was defined as a significant reduction in metabolic activity or lesion size consistent with partial tumor shrinkage as per Lugano criteria.

    Measured: From first dose to primary analysis data cutoff (12 Dec 2022) or new anti-lymphoma therapy start, whichever came first. Median follow-up was 11.4 months.

Secondary outcomes (4)

  1. Complete Response Rate (CRR)

    CRR was defined as the percentage of participants who achieved a best overall response of complete response (CR) by PET-CT or CT per the Lugano Classification and determined by the investigator. CR was defined as the complete disappearance of all target lesions on PET-CT or CT, with no new lesions detected.

    Measured: From first dose to primary analysis data cutoff (12 Dec 2022) or new anti-lymphoma therapy start, whichever came first. Median follow-up was 11.4 months.

  2. Duration of Response (DOR)

    DOR was defined as the time from the date that response criteria (CR or PR) were first met to the date of objectively documented disease progression or death, whichever occurred first. Participants without an event were censored at the data cutoff or end of study, whichever occurred first. Participants who received new anti-lymphoma therapies, including Hematopoietic Stem Cell Transplantation (HSCT), before having an event were censored at the date of therapy initiation. Only participants with confirmed response were included in the analysis. Median DOR was estimated using the Kaplan-Meier method.

    Measured: From first dose to primary analysis data cutoff (12 Dec 2022) or new anti-lymphoma therapy start, whichever came first. Median follow-up was 11.4 months.

  3. Time to Response (TTR)

    TRR was defined as the time from the date of the first dose of tislelizumab to the date the response criteria were first met CR or PR per the Lugano Classification, and was analyzed only in participants who achieved an overall response; CR was defined as complete disappearance of disease, PR as ≥50% reduction in tumor burden, and Overall Response Rate (ORR) included participants with either CR or PR.

    Measured: From first dose to primary analysis data cutoff (12 Dec 2022) or new anti-lymphoma therapy start, whichever came first. Median follow-up was 11.4 months.

  4. Number of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    Adverse events (AEs) were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0. Treatment-emergent adverse events (TEAEs) were defined as any AE that began or worsened in severity after the first dose of study treatment and up to 90 days following the last dose, regardless of initiation of new anti-lymphoma therapy. The following safety data are reported:

    Number of participants with any TEAEs: Participants who experienced at least one TEAE of any grade.

    Number of participants with any Grade ≥3 TEAEs: Participants who experienced at least one TEAE that was Grade 3 or higher in severity.

    Number of participants with any SAEs: Participants who experienced at least one serious adverse event, regardless of relationship to study treatment, occurring up to 90 days after the last dose.

    Measured: From the date of the first dose of tislelizumab through 90 days after the last dose (maximum duration of tislelizumab exposure was 168 weeks)

Individual data sharing
Yes: BeiGene 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. BeiGene 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 BeiGene review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tislelizumab in people with Classical Hodgkin Lymphoma, run by BeiGene at 4 sites in 2 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 13 inclusion and 5 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: finished, as of the sponsor's last update on 24 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Australia. 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?

Yes. Results are posted in the registry (first posted 24 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Response Rate (ORR) (time frame: From first dose to primary analysis data cutoff (12 Dec 2022) or new anti-lymphoma therapy start, whichever came first. Median follow-up was 11.4 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 NCT04318080, which also lists 3 linked publications.

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 24 Sep 2025.
