Outcome Measures
Primary Outcomes (1)
Dose Limiting Toxicity (DLT) Events
The occurrence of a severe adverse event (meeting pre-specified criteria) that is at least possibly related to durvalumab and/or the novel oncology therapy in 6 DLT-evaluable patients
From the time of first dose until completion of the first cycle (28 days for Arms 2-5, 21 days for Arms 6-7 (no safety run-in for Arms 1 and 8))
Secondary Outcomes (6)
Objective Response Rate (ORR)
Tumor assessments: every 8 wks (Arms 1-5) or every 6 wks (Arms 6-8) until wk 48, then every 12 wks from first IP dose until radiologic progression, death, withdrawal of consent, or study completion; up to max 54 mos (observed longest duration in Arm 1)
Progression-free Survival (PFS)
Tumor assessments: every 8 wks (Arms 1-5) or every 6 wks (Arms 6-8) until wk 48, then every 12 wks from first IP dose until radiologic progression, death, withdrawal of consent, or study completion; up to max 54 mos (observed longest duration in Arm 1)
Duration of Response (DoR)
Tumor assessments: every 8 wks (Arms 1-5) or every 6 wks (Arms 6-8) until wk 48, then every 12 wks from first IP dose until radiologic progression, death, withdrawal of consent, or study completion; up to max 54 mos (observed longest duration in Arm 1)
Overall Survival (Count)
From date of first dose until date of death due to any cause; up to the maximum of 54 months (observed longest duration in Arm 1)
Overall Survival (Duration)
From date of first dose of IP until date of death due to any cause; up to the maximum of 54 months (observed longest duration in Arm 1)
