-
Use of hematopoietic colony-stimulating growth factors (eg, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), macrophage colony-stimulating factor (M-CSF)) ≤ 3 weeks prior to start of Tebentafusp. An erythroid-stimulating agent is allowed as long as it was initiated at least 3 weeks prior to the first dose of study treatment and the patient is not red blood cell (RBC) transfusion dependent. For more information on the timing and use of hematopoietic colony-stimulating growth factors during study.

Group Intervention Description Tebentafusp in combination with Radioembolization Group Tebentafusp Participants in this group will first be administered Yttrium 90 Trans-Arterial Radioembolization (Y90 TARE) therapy, followed by a 14 to 28 day recovery period. Participants will then be administered Tebentafusp once weekly during every 28-day cycle. Participants may receive up to 24 months or 24 cycles of Tebentafusp therapy. Total participation is about 3 years. Tebentafusp in combination with Radioembolization Group TheraSphere™ Yttrium-90 Trans-Arterial Radioembolization Participants in this group will first be administered Yttrium 90 Trans-Arterial Radioembolization (Y90 TARE) therapy, followed by a 14 to 28 day recovery period. Participants will then be administered Tebentafusp once weekly during every 28-day cycle. Participants may receive up to 24 months or 24 cycles of Tebentafusp therapy. Total participation is about 3 years.
- Primary Outcome Measures
Name Time Method Progression Free Survival (PFS) Up to 24 months Progression-free survival (PFS) will be defined as the elapsed time in months from the first date of study treatment until documented disease progression, per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or death from any cause, whichever is earlier. For participants who remain alive without progression, follow-up time will be censored at the date of last disease assessment.
Number of Participants Experiencing Treatment-Related Adverse Events Up to 24 months The number of participants experiencing treatment-related adverse events (AEs) and serious adverse events (SAEs) in participants receiving protocol therapy will be assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5, per physician discretion.
- Secondary Outcome Measures
Name Time Method Disease control rate (DCR) measured by proportion of patients Up to 24 months Disease control rate (DCR) is the proportion of patients whose best response per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria is complete response (CR), partial response (PR), or stable disease (SD) confirmed with new assessments by CT or MRI imaging prior to starting new anticancer therapies. Response recorded after non-protocol anticancer therapy will not be counted.
Overall response rate (ORR) Up to 2 years Overall response rate (ORR) is the proportion of patients whose best overall response per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria is complete response (CR) or partial response (PR). Response recorded after non-protocol anticancer therapy will not be counted.
Duration of response (DOR) Up to 24 months The duration of overall response (DOR) is measured from the time in months measurement criteria are met for complete response (CR) or partial response (PR) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started). For participants without progression, follow-up time will be censored at the date of last disease assessment (as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1).
Overall survival (OS) Up to 3 years Overall survival (OS) is defined as the elapsed time in years from date of first study treatment until death from any cause. Participants without documented death will be censored at the last date known to be alive.
