E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Part A: The primary objective of the trial is to assess the clinical activity of Avelumab as determined by the objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) in subjects with metastatic MCC after failing first-line chemotherapy. Part B: The primary objective is to evaluate the clinical activity of avelumab as first-line treatment for metastatic or distally recurrent MCC as determined by the durable response rate (DRR) according to RECIST 1.1 by an IERC. |
|
E.2.2 | Secondary objectives of the trial |
Part A: Secondary objectives are as follows: • To assess the duration of response according to RECIST 1.1 • To assess the progression-free survival time (PFS) according to RECIST 1.1 • To assess the safety profile of avelumab in subjects with MCC • To assess the overall survival (OS) time Part B: Secondary objectives are as follows: •To assess the OS time •To assess ORR according to RECIST 1.1 •To assess the duration of response according to RECIST 1.1 •To assess the PFS according to RECIST 1.1 •To assess the safety profile of avelumab in subjects with MCC |

E.4 | Principal exclusion criteria |
1.Participation in another interventional clinical trial within the past 30 days (participation in observational studies is permitted) 2. Concurrent treatment with a nonpermitted drug 3. Prior therapy with any antibody/drug targeting T-cell coregulatory proteins (immune checkpoints) such as anti-PD-1, anti-PD-L1, or anticytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody; for Part B, the Investigator must consult with the Medical Monitor and consider other co regulatory targets such as 4-1BB 4. Concurrent anticancer treatment (for example, cytoreductive therapy, radiotherapy [with the exception of palliative bone-directed radiotherapy, or radiotherapy administered on non-target superficial lesions], immune therapy, or cytokine therapy except for erythropoietin). Radiotherapy administered to superficial lesions is not allowed if such lesions are considered target lesions in the efficacy evaluation or may influence the efficacy evaluation of the investigational agent 5.

Concurrent systemic therapy with steroids or other immunosuppressive agents, or use of any investigational drug within 28 days before the start of trial treatment. Short-term administration of systemic steroids (that is, for allergic reactions or the management of irAEs) is allowed while on study. Note: Subjects receiving bisphosphonate or denosumab are eligible. Also, subjects requiring hormone replacement with corticosteroids for adrenal insufficiency are eligible if the steroids are administered only for the purpose of hormonal replacement and at doses ≤ 10 mg or equivalent prednisone per day. 7. Subjects with active central nervous system (CNS) metastases are excluded. Subjects with a history of treated CNS metastases (by surgery or radiation therapy) are not eligible unless they have fully recovered from treatment, demonstrated no progression for at least 2 months, and do not require continued steroid therapy 8. Previous malignant disease (other than MCC) within the last 5 years with the exception of basal or squamous cell carcinoma of the skin or cervical carcinoma in situ 9. Prior organ transplantation, including allogeneic stem-cell transplantation 10. For Part A, Known history of testing positive for HIV or known acquired immunodeficiency syndrome (AIDS) or any positive test for hepatitis B virus or hepatitis C virus indicating acute or chronic infection. For Part B, known history of testing positive for HIV or known AIDS in consultation with the Medical Monitor or HBV or HCV infection at screening (positive HBV surface antigen or HCV RNA if anti- HCV antibody screening test positive) 11. Active or history of any autoimmune disease (except for subjects with vitiligo) or immunodeficiencies that required treatment with systemic immunosuppressive drugs 12. Known severe hypersensitivity reactions to monoclonal antibodies (Grade ≥ 3 NCI-CTCAE v 4.0), any history of anaphylaxis, or uncontrolled asthma (that is, 3 or more features of partly controlled asthma) 13. Persisting toxicity related to prior therapy Grade > 1 NCI-CTCAE v 4.0; however, sensory neuropathy Grade ≤ 2 is acceptable 14. Pregnancy or lactation 15. Known alcohol or drug abuse 16. Clinically significant (that is, active) cardiovascular disease: cerebral vascular accident / stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (New York Heart Association Classification Class ≥ II), or serious cardiac arrhythmia requiring medication 17. All other significant diseases (for example, inflammatory bowel disease), which, in the opinion of the Investigator, might impair the subject’s tolerance of trial treatment 18. Any psychiatric condition that would prohibit the understanding or rendering of informed consent 19. Legal incapacity or limited legal capacity 20. Nononcology vaccine therapies for prevention of infectious disease (for example, seasonal flu vaccine, human papilloma virus vaccine) within 4 weeks of trial drug administration. Vaccination while on trial is also prohibited except for administration of inactivated vaccines (for example, inactivated seasonal influenza vaccine)
