Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessment of the antitumor activity of MEDI5752 (independently for eah cohort)	Antitumor activity will be assessed in terms of objective response rate within 24 weeks based on RECIST v1.1, independently for each cohort, and based on centralized radiological review.; Objective response under treatment is defined as patients with confirmed complete response or confirmed partial response, as per RECIST v1.1, observed during treatment with the investigational product.; Objective response rate is defined as the proportion of patients alive with objective response based on RECIST v1.1.; Objective response is recorded from study treatment initiation until the end of treatment.	an expected average of 6 months
Secondary	24-weeks clinical benefit rate (CBR) independently for each cohort	CBR is defined as the proportion of patients with clinical benefit at 6 months. Clinical benefit is defined as confirmed complete response, confirmed partial response or stable disease more than 24 weeks, defined as per RECIST v1.1.	24 weeks
Secondary	Best overall response (BoR) independently for each cohort	BoR is defined as the best response recorded from the start of the study treatment until the end of treatment taking into account any requirement for confirmation. The best overall response is determined once all the data for the participant is known (RECIST v1.1).	Throughout the treatment period, an expected average of 6 months
Secondary	Duration of response (DoR) independently for each cohort	DoR is defined as the time from documentation of tumor response (complete response/partial response whichever is first recorded) to disease progression, according to RECIST v1.1. DoR will be assessed in responder (confirmed CR / PR) patients only.	Throughout the treatment period, an expected average of 6 months
Secondary	1-year progression-free survival (PFS), independently for each cohort	PFS is defined as the time from study treatment initiation to the first occurrence of disease progression or death (of any cause), whichever occurs first	1 year
Secondary	2-year progression-free survival (PFS), independently for each cohort	PFS is defined as the time from study treatment initiation to the first occurrence of disease progression or death (of any cause), whichever occurs first	2 year
Secondary	1-year overall survival (OS), independently for each cohort	OS is defined as the time from study treatment initiation to death (of any cause)	1 year
Secondary	2-year overall survival (OS), independently for each cohort	OS is defined as the time from study treatment initiation to death (of any cause)	2 year
Secondary	Safety profile, independently for each cohort: Common Terminology Criteria for Adverse Events version 5	Number of participants with toxicity graded using the Common Terminology Criteria for Adverse Events version 5	Throughout the treatment period, an expected average of 6 months
Secondary	24-weeks clinical benefit rate (iCBR) independently for each cohort as per iRECIST	iCBR is defined as the rate of patients with iCR, iPR or immune stable disease (iSD)	24 weeks
Secondary	Duration of response (iDoR) independently for each cohort as per iRECIST	iDoR is defined as the time from the date of the first response iCR/iPR (whichever is first recorded) to the date of PD (iUPD confirmed as iCPD) as per iRECIST. iDOR is defined for subjects with iCR or iPR. If a patient has iPR (#1) followed by a iUPD (#1) which is not confirmed, then a iPR (#2) followed by a iUPD (#2) which is confirmed at the next assessment, then the iDOR is calculated from iPR1 until iUPD2	Throughout the treatment period, an expected average of 6 months
Secondary	1-year progression-free survival (iPFS), independently for each cohort as per iRECIST	o iPFS is defined as the time from study treatment initiation to the first occurrence of disease progression as per iRECIST or death (of any cause), whichever occurs first. The event date to be used for calculation of progression-free survival (iPFS) should be the first date at which progression criteria are met (ie, the date of iUPD) provided that iCPD is confirmed at the next assessment. If iUPD occurs, but is disregarded because of later iSD, iPR, or iCR, that iUPD date should not be used as the progression event date. If progression is not confirmed and there is no subsequent iSD, iPR, or iCR, then the iUPD date should still be used in the following scenarios: if the patient stops protocol treatment because they were not judged to be clinically stable, or no further response assessments are done (because of patient refusal, protocol noncompliance, or patient death); the next timepoint responses are all iUPD, and iCPD never occurs	1 year
Secondary	2-year progression-free survival (iPFS), independently for each cohort as per iRECIST	o iPFS is defined as the time from study treatment initiation to the first occurrence of disease progression as per iRECIST or death (of any cause), whichever occurs first. The event date to be used for calculation of progression-free survival (iPFS) should be the first date at which progression criteria are met (ie, the date of iUPD) provided that iCPD is confirmed at the next assessment. If iUPD occurs, but is disregarded because of later iSD, iPR, or iCR, that iUPD date should not be used as the progression event date. If progression is not confirmed and there is no subsequent iSD, iPR, or iCR, then the iUPD date should still be used in the following scenarios: if the patient stops protocol treatment because they were not judged to be clinically stable, or no further response assessments are done (because of patient refusal, protocol noncompliance, or patient death); the next timepoint responses are all iUPD, and iCPD never occurs	2 year
Secondary	iORR independently for each cohort	iORR is defined as the rate of patients with immune complete or partial responses (iCR, iPR) as per iRECIST. iCR and iPR can be assigned after iUPD (immune unconfirmed progressive disease) has been documented as per iRECIST (Seymour et al)	Throughout the treatment period, an expected average of 6 months
