Study Endpoints

Primary Endpoints

Incidence and Severity of Dose Limiting Toxicities (DLTs)
up to 12 weeks

A DLT is defined as any grade 4+ non-hematologic event lasting greater than 3 days (despite appropriate medical management) considered possibly related to study treatment (HEPZATO KIT™ or Opdualag™) within 12 weeks of Cycle 1 Day 1.

Incidence of Treatment-Emergent Adverse Events
up to 2 years
Incidence of Serious Treatment-Emergent Adverse Events
up to 2 years
Number of Participants that Discontinue Treatment due to Adverse Events
up to 2 years
Overall Response Rate (ORR)
After treatment plus follow up for 2 years (up to 4 years)

The objective response rate is the proportion of all participants with confirmed Partial Response (PR) or Complete Response (CR) according to RECIST 1.1, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment).

Secondary Endpoints

ORR in Hepatic and Non-Hepatic Lesions
After treatment plus follow up for 2 years (up to 4 years)
Disease Control Rate (DCR)
After treatment plus follow up for 2 years (up to 4 years)
