Tislelizumab in Participants With Relapsed or Refractory Classical Hodgkin Lymphoma (TIRHOL)

September 17, 2025 updated by: BeiGene

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.

Description

Key Inclusion Criteria:

  1. Participants had a histologically confirmed diagnosis of relapsed or refractory classical Hodgkin lymphoma (cHL).

    1. Were not considered candidates for autologous or allogeneic HSCT.
    2. Had received at least one prior systemic therapy regimen for cHL.
  3. Participants had measurable disease, defined as at least one positron emission tomography (PET)-positive, 2-\[18F] fluoro-2-deoxy-D-glucose (FDG)-avid nodal lesion greater than 1.5 centimeters (cm) in longest diameter, or at least one FDG-avid extranodal lesion (hepatic nodule) greater than 1.0 cm in longest diameter.
  4. Participants had an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1, indicating full activity or restricted activity but capable of self-care.

Key Exclusion Criteria:

  1. Participants had nodular lymphocyte-predominant Hodgkin lymphoma or gray zone lymphoma.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
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.
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Complete Response Rate (CRR)
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.
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.
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.
Duration of Response (DOR)
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.
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.
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.
Time to Response (TTR)
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.
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.
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.
Number of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Time Frame: From the date of the first dose of tislelizumab through 90 days after the last dose (maximum duration of tislelizumab exposure was 168 weeks)

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

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

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.
