Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The number of patients with adverse events	Number of patients with adverse events by system organ class and preferred term	From time of Informed consent to 30 days post last dose (approximately 1 year).
Primary	The number of patients with serious adverse events	Number of patients with serious adverse events by system organ class and preferred term	From time of Informed consent to 30 days post last dose (approximately 1 year)
Primary	The number of patients with dose-limiting toxicity (DLT), as defined in the protocol.	A DLT is defined as any toxicity that occurs from the first dose of study treatment up to and including the planned end of Cycle 1 (the DLT assessment period) that is assessed as unrelated to the disease or disease-related processes under investigation and which includes pre-defined haematological and non-haematological toxicities.	From first dose of study treatment until the end of Cycle 1 (approximately 21 days).
Primary	The number of patients with changes from baseline laboratory findings, ECGs and vital signs	Description of laboratory findings and vital signs variables over time including change from baseline.	From time of informed consent to 30 days post last dose (approximately 1 year)
Secondary	Objective Response Rate (ORR)	The percentage of patients with a confirmed investigator assessed complete or partial response according to response criteria in solid tumours (RECIST 1.1).	From first dose of AZD8205 to progressive disease or death in the absence of disease progression ( approx. 2 years )
Secondary	Duration of response (DoR)	The time from the date of first response until date of disease progression or death in the absence of disease progression.	From the first documented response to confirmed progressive disease or death ( approx. 2 years )
Secondary	Progression free Survival (PFS)	The time from first dose until RECIST 1.1 defined disease progression or cessation of study treatment.	From first dose of AZD8205 to progressive disease or death in the absence of disease progression ( approx. 2 years )
Secondary	Disease Control Rate at 12 weeks (DCR-12)	Percentage of patients with confirmed CR or PR or having SD maintained for >= 11 weeks from first dose.	Measured from first dose until progression. For each patient, this is expected to be at 12 weeks
Secondary	Overall Survival (OS)	The time from the date of the first dose of study treatment until death due to any cause.	From first dose of AZD8205 to death ( approx. 2 years )
