Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR)	Objective Response Rate (ORR) defined as the percentage of patients having a confirmed CR or PR according to RECIST v1.1	up to 24 months
Secondary	Durable Response Rate (DRR)	Durable Response Rate (DRR), defined as the percentage of patients having a RECIST v1.1 response lasting = 6 months	up to 24 months
Secondary	Duration of Response (DoR)	Duration of Response (DoR), defined as the time from an initial objective response (CR or PR) according to RECIST v1.1 until disease progression or death due to any cause	up to 24 months
Secondary	Disease Control Rate (DCR)	Disease Control Rate (DCR), defined as the proportion of patients with either an objective response (CR, PR) or stable disease (SD) according to RECIST v1.1.	up to 24 months
Secondary	Durable Disease Control Rate (dDCR)	Durable Disease Control Rate (dDCR), defined as the percentage of patients having a RECIST v1.1 disease control lasting = 6 months	up to 24 months
Secondary	Best Overall response (BOR)	Best Overall response (BOR), defined as the best response (PD, SD, PR, CR) according to RECIST v1.1 over the course of a patient's participation in the study, assessed up to 2 years	up to 24 months
Secondary	Progression Free Survival (PFS)	Progression Free Survival (PFS), defined as the time from first dosing (Day +1) to the date of PD or death from any cause (whichever comes first)	up to 24 months
Secondary	PFS Rate	PFS Rate, defined as the percentage of patients without PD at 6 and 12 months after first administration of study drug	up to 24 months
Secondary	Overall Survival (OS)	Overall Survival (OS), defined as the time from the first administration of study medication until death due to any cause	up to 36 months
Secondary	OS Rate	OS Rate, defined as the percentage of patients alive at 6 and at 12 months after first administration of study drug	up to 12 months
Secondary	Safety and Tolerability	Safety and Tolerability of the study medication (determined by number, frequency, duration and severity of AEs using CTCAE v5.0, physical examination, laboratory tests, vital signs, and ECGs)	up to 24 months
Secondary	Health related Quality of Life (HrQoL)	The impact of treatment on the patient's QoLwill be assessed with the questionnaires "Functional Assessment of Cancer Therapy - Melanoma (FACT-M)" where QoL is assessed on a scale 0-240 (higher score means better status of health), with "EQ-5D-5L" which is a multi attribute utility instrument for measuring health-related QoL as EQ5D index with a score 0-1 (higher score means better status of health) and with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) with a score 0-100 per subscale (n=9 per item (n=6), higher score means better QoL.	up to 24 months
Secondary	Plasma concentration of domatinostat and avelumab	Single trough values of domatinostat and avelumab at pre-defined time points	up to 48 weeks
Secondary	Avelumab anti-drug antibodies (ADA)	Avelumab anti-drug antibodies (ADA)	up to 48 weeks
