Dose Limiting Toxicity (DLT) Events Primary · 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))

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

Objective Response Rate (ORR) Secondary · 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)

Percentage of evaluable patients with a confirmed Investigator-assessed response of CR (complete response) or PR (partial response). Confirmed response is defined as at least one visit response of CR or PR confirmed by a follow-up scan at least 4 weeks later showing CR or PR.

Duration of Response (DoR) Secondary · 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)

Time from the date of first documented response (which is subsequently confirmed) until the first date of documented progression (PD) or death in the absence of PD (ie, date of PFS event or censoring - date of first response + 1). If a patient does not progress following a response, then their DoR will be censored at the last evaluable disease assessment date

Adverse events — posted to ClinicalTrials.gov

Time frame: From the time of signature of informed consent up to 90 days after the last dose of study treatment. If an event starts post this period noted and is considered to be due to a late-onset toxicity to study drug, then it should be reported as an AE/SAE. Maximum duration of approximately 54 months.. Reporting threshold: 5%. Adverse-event reports describe events observed during the trial — not all are caused by the drug.
