Primary Outcome Measures :
  1. disease control rate (DCR) after 16 weeks of avelumab treatment [ Time Frame: 16 weeks ]
    The primary endpoint is the disease control rate (DCR) after 16 weeks of avelumab treatment. DCR is defined as the percentage of subjects with a confirmed reduction in tumor size compared to baseline (complete response (CR) and partial response (PR)) as well as fulfilling the criteria for stable disease (SD) according RECIST1.1.

Secondary Outcome Measures :
  1. disease control rate (DCR) on other assessments [ Time Frame: 8, 24, 36, 48, 60 weeks ]
    Disease control rate (DCR) on other assessments. DCR is the proportion of patients with complete response, partial response and stable disease according to RECIST1.1.

  2. Objective response rate (ORR) on every assessment [ Time Frame: 8, 16, 24, 36, 48, 60 weeks ]
    Objective response rate (ORR) on every assessment. ORR is the proportion of patients with complete response (CR) or partial response (PR) according to RECIST1.1.

  3. Best overall response (BOR) [ Time Frame: 8, 16, 24, 36, 48, 60 weeks ]
    Best overall response (BOR). BOR is recorded from the start of the treatment until disease progression/recurrence according to RECIST1.1.

  4. Duration of disease control [ Time Frame: up to 1 year ]
    Duration of disease control: Duration of disease control is defined as the time from the first disease control (CR, PR, SD) to progression of disease (PD) according to RECIST1.1.

  5. Time to response (TTR) [ Time Frame: up to 1 year ]
    Time to response (TTR): TTR is the time from the first dose of trial medication to the first documentation of either complete response (CR) or partial response (PR) according to RECIST1.1.

  6. Median Progression-free survival time (PFS) [ Time Frame: up to 2 years ]
    Median Progression-free survival time (PFS). The time from first dose of trial medication to first documentation of objective tumor progression (PD) or to death due to any cause, whichever occurs first.

  7. Overall survival (OS) and survival rate after 1 and 2 years [ Time Frame: up to 2 years ]
    Overall survival (OS) and survival rate after 1 and 2 years: Overall survival is defined as the time from first dose of trial medication to date of death due to any cause. Survival rate is defined as rate of subjects surviving for at least 1 year or 2 years after first application of trial medication.

  8. Quality of life (QoL) [ Time Frame: 0, 8, 16, 24, 36, 48, 52, 60 weeks ]
    Quality of life (QoL) assessed by the EORTC QLQ-C30 questionnaire on Screening/Baseline, during Treatment on every assessment, on End of Treatment and on Safety FU visit

  9. Incidence of adverse events (AEs) [ Time Frame: 60 weeks ]
    Reporting of number and frequency of adverse Events (AEs) during treatment with avelumab and until Safety Follow

Other Outcome Measures:
  1. assessment of serum levels in Chromatogranin A (CgA) [ Time Frame: 0, 8, 16, 24, 36, 48, 60 weeks ]
    assessment of serum levels in Chromatogranin A (CgA) measured at time of tumor assessments

  2. assessment of serum levels in Neuron specific enolase (NSE) [ Time Frame: 0, 8, 16, 24, 36, 48, 60 weeks ]
    assessment of serum levels in and Neuron specific enolase (NSE) measured at time of tumor assessments

  3. Tumor growth rate (TGR) [ Time Frame: 0, 8, 16, 24, 36, 48, 60 weeks ]
    Tumor growth rate (TGR): TGR is the percentage change in tumor volume over one month

  4. Tumor response according to irRECIST [ Time Frame: 8, 16, 24, 36, 48, 60 weeks ]
    Tumor response according to irRECIST
