13. History of other disease, metabolic dysfunction, physical examination finding, or
clinical laboratory finding that based on the investigator's judgement provides a
reasonable suspicion of a disease or condition that contraindicates the use of an
investigational drug or that might affect the interpretation of the trial results or
render the patient at high risk for treatment complications
14. Previous malignant disease (other than the tumor disease for this trial) within the
last 5 years (except adequately treated non-melanoma skin cancers, carcinoma in situ

16. Active autoimmune disease that might deteriorate when receiving an immunostimulatory
agent:
1. Subjects with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease
not requiring immunosuppressive treatment are eligible
2. Administration of steroids through a route known to result in a minimal systemic
exposure (topical, intranasal, intro-ocular, or inhalation) are acceptable
17. History of uncontrolled intercurrent illness including but not limited to uncontrolled
diabetes (e.g., hemoglobin A1c ≥ 8%)
18. Known prior hypersensitivity to investigational product or any component in its
formulations or any other drug scheduled or likely to be given during the trial,
including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE
v5.0 Grade ≥ 3)
19. Persisting toxicity related to prior therapy (NCI CTCAE v5.0 Grade > 1); however,
alopecia, sensory neuropathy Grade ≤ 2, or other Grade ≤ 2 AEs not constituting a
safety risk based on investigator's judgment are acceptable
20. Other severe acute or chronic medical conditions including immune colitis,
inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric
conditions including recent (within the past year) or active suicidal ideation or
behavior, or laboratory abnormalities that may increase the Risk associated with trial
participation or trial treatment administration or may interfere with the
interpretation of trial results and, in the judgment of the investigator, would make
the patient inappropriate for entry into this trial
21. Active infection requiring systemic therapy
22. Known history of human immunodeficiency virus (HIV) or known acquired immunodeficiency
syndrome or multi-drug resistant gram-negative bacteria
23. Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive
HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive)
24. Women of childbearing potential

detachment, uveitis Prior and concomitant medication
26. Treatment in any other clinical trial within 30 days or within 5 half lives of any
prior treatment, before screening

interfere with the trial or current drug or substance abuse

1. Corticosteroids (except steroids up to equivalent of dexamethasone 4 mg daily
dose)
2. Immunosuppressive agents
3. Antibiotics
4. Bevacizumab or any other anti-angiogenic treatment
5. Any other anti-cancer therapy or concurrent anticancer treatment, for example,
cytoreductive therapy, radiotherapy [with the exception of palliative short
course, limited field (ie, ≤ 10 fractions and ≤ 30% bone marrow involvement or
per institutional standard) radiotherapy, which may be administered during the
study. However dosing must be suspended at least 14 days prior to the start of
radiotherapy and must not be resumed until at least 14 days after the last
radiotherapy fraction], immune therapy, or cytokine therapy, except for
erythropoietin
6. Administration of live vaccines (other than VXM01) within 30 days prior to study
treatment Other
29. Vaccination within 4 weeks of the first dose of avelumab and while on trials is
prohibited except for administration of inactivated vaccines (other than VXM01)
30. Inability to understand the protocol requirements, instructions and trial-related
restrictions, the nature, scope, and possible consequences of the trial
31. Unlikely to comply with the protocol requirements, instructions and trial-related
restrictions; e.g., uncooperative attitude, inability to return for follow-up visits,
and improbability of completing the trial
