Study Endpoints

Primary Endpoints

Safety as assessed by number of participants experiencing adverse events
48 months

Number of participants experiencing adverse events grade three or higher, as defined by Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0). Severity is a measure of intensity (eg, grade of a specific AE, mild \[Grade 1\], moderate \[Grade 2\], severe \[Grade 3\], or life-threatening \[Grade 4\]), whereas seriousness is classified by the criteria based on the regulatory definitions. Seriousness serves as the guide for defining regulatory reporting obligations from the Investigator Sponsor to applicable regulatory authorities as described in CTCAE version 5.0.

Secondary Endpoints

Response and progression will be evaluated in this trial using the international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee (v1.1).

ArmTypeDescription
Tislelizumab in conjunction with radiation therapyEXPERIMENTALParticipants will receive local therapy including TACE+ RT or Ablation (tumors with incomplete ablation) + RT or RT alone (for patients not eligible for TACE or Ablation) and will be screened for eligibility prior to enrollment. Once eligibility has been confirmed, Tislelizumab will be started before radiation therapy and will continue after radiation therapy. Participants who do not receive Tislelizumab for a total of two cycles will be replaced and interpreted for only toxicity analysis.

Interventions

NameTypeDescription
TislelizumabDRUGTislelizumab (also known as BGB A317) is a humanized, immunoglobulin G4 (IgG4)-variant monoclonal antibody against programmed cell death protein-1 (PD-1) under clinical development for the treatment of several human malignancies. Tislelizumab consolidation therapy after radiation therapy can capitalize on the immunomodulatory effect of radiotherapy and improve tumor responses and patient outcomes.
