Time Frame: Cohort 1: From time of first dose of MEDI4736 on Day 1 up to Day 28 of Cycle 1 and Cohort 2: From time of first dose of AZD5069 and MEDI4736 on Day 1 up to Day 28 of Cycle 1 or until a participant experiences a DLT, whichever occurs first.
|
DLT period was defined as first treatment cycle for Cohort 1, and first dose of AZD5069 and MEDI4736 to end of Cycle 1 or until a participant experienced a DLT, whichever occurs first for Cohort 2. A DLT was defined as any of below listed laboratory abnormalities or adverse events (AE) related to MEDI4736 collected during DLT period.
|
Cohort 1: From time of first dose of MEDI4736 on Day 1 up to Day 28 of Cycle 1 and Cohort 2: From time of first dose of AZD5069 and MEDI4736 on Day 1 up to Day 28 of Cycle 1 or until a participant experiences a DLT, whichever occurs first.
|
Number of Participants With AEs
Time Frame: From first dose of study treatment administration (Day 1) until 90 days after the last dose of IP or initiation of the first subsequent anticancer therapy (whichever occurred first), approximately 30 months.
|
An AE is the development of an undesirable medical condition or deterioration of a pre-existing medical condition following or during exposure to study treatment, whether or not considered causally related to study treatment.
An undesirable medical condition can be symptoms, signs or abnormal results of an investigation.
A serious AE (SAE) is an AE that fulfills one or more following criteria: death, life-threatening, in-patient hospitalization or prolongation of existing hospitalization, persistent or significant disability/incapacity or substantial disruption of ability to conduct normal life functions, congenital abnormality or birth defect, and an important medical event that may jeopardize participant or may require medical intervention to prevent one of outcomes listed above.
AEs leading to discontinuation of study treatment were those with action taken was 'Drug Permanently Discontinued' for any study treatment.
Only treatment emergent AEs were presented.
|
From first dose of study treatment administration (Day 1) until 90 days after the last dose of IP or initiation of the first subsequent anticancer therapy (whichever occurred first), approximately 30 months.
|
Objective Response Rate (ORR) in Cohort 2
Time Frame: RECIST assessments performed at baseline (within 28 days before start of study treatment), every 6 weeks +/-7 days for first 48 weeks, then every 12 weeks +/-7 days thereafter until confirmed objective disease progression. Up to approximately 30 months.
|
ORR is defined as the percentage of participants with a confirmed overall response of complete response (CR) or partial response (PR).
A confirmed response of CR/PR means that a response of CR/PR is recorded at 1 visit and confirmed by repeat imaging, preferably at the next regularly scheduled imaging visit and not less than 4 weeks after the visit when the response was first observed with no evidence of progression between the initial and CR/PR confirmation visit.
CR is defined as disappearance of all target lesions (TLs) since baseline.
Any pathological lymph nodes selected as TLs must have a reduction in short axis to <10 millimeters (mm).
PR is defined as at least a 30% decrease in the sum of diameters of TLs, taking as reference the baseline sum of diameters as long as criteria for PD were not met.
ORR was determined using Investigator assessments according to Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1).
|
RECIST assessments performed at baseline (within 28 days before start of study treatment), every 6 weeks +/-7 days for first 48 weeks, then every 12 weeks +/-7 days thereafter until confirmed objective disease progression. Up to approximately 30 months.
