International Myeloma Working Group Criteria (IMWG)(3). Patients at initial diagnosis
must have had a serum M-protein greater than or equal to 3 g/dL and/or bone marrow
plasma cells greater than or equal to 10%, and at least one of the following:
- Anemia: Hemoglobin less than or equal to10 g/dL, or
- Renal failure: serum creatinine greater than or equal to 2.0 mg/dL, or
- Hypercalcemia: Calcium (Ca) greater than or equal to10.5 mg/dL, or

therapy
- Must have Relapsed or Relapsed and Refractory Multiple Myeloma. Patients must have
documented evidence of progressive disease (PD) as defined by the IMWG criteria on or
after their last regimen and must have achieved a minimal response (MR) or better to
at least one prior regimen. Definitions by the IMWG:
- Relapsed and refractory: disease that is nonresponsive while on salvage therapy
or progresses within 60 days of last therapy in patients who have achieved minor
response (MR) or better
- Relapsed: disease that progresses and requires the initiation of salvage therapy
but does not meet criteria for either primary refractory or relapsed and
refractory MM categories
- Patients must have been previously treated for MM and be refractory to, not a
candidate for (ineligible), or intolerant of available therapeutic regimens known to
provide clinical benefit including immunomodulatory (IMiD), proteasome inhibitor, and
anti-cluster of differentiation (CD)38 monoclonal antibody-based treatments.
- Documented measurable disease within the 4 weeks prior to registration defined by any
one of the following:

- Serum immunoglobulin free light chain >10 mg/dL AND abnormal kappa/lambda ratio
- A measurable lesion on PET/CT or MRI
- Be greater than or equal to 18 years of age on day of signing informed consent
Note: The estimated 2017 US incidence of MM of patients under the age of 20 is 0.0%;
therefore, children are excluded from enrollment in this study.

Chronic Kidney Disease Epidemiology Collaboration (CKD- EPI) formula may be used to
estimate CrCl/eGFR greater than or equal to 30 mL/min/1.73 m(2) for subject with
creatinine levels > 1.5 X ULN
- Serum total bilirubin less than or equal to 1.5 X ULN OR Direct bilirubin less than or
equal to ULN for patients with total bilirubin levels > 1.5 ULN (except if due to
myeloma)
- Aspartate aminotransferase (AST) serum glutamic-oxaloacetic transaminase (SGOT) and
alanine aminotransferase (ALT) serum glutamic pyruvic transaminase (SGPT) less than or
equal to 2.5 X ULN (except if due to myeloma)
- The effects of avelumab on the developing human fetus are unknown, however, given
the known role of Programmed Cell Death Ligand 1 (PD-1)/Programmed death-ligand 1
(PD-L1) in maintaining the maternal/fetal tolerance, avelumab can be expected to
have an adverse effect on pregnancy, including embryo-lethality. Women of
child-bearing potential (WOCBP) and men must agree to use highly effective
contraception (such as implants, injectables, combined oral contraceptives,
intrauterine device (IUDs), sexual abstinence or vasectomised partner) prior to
study entry and for the duration of study treatment, and for at least 30 days
after the last dose of avelumab. Should a woman become pregnant or suspect she is
pregnant while she or her partner is participating in this study, she should
inform her treating physician immediately.
NOTE: WOCBP is defined as any female who has experienced menarche and who has not undergone
successful surgical sterilization or who is not postmenopausal.
- Negative serum or urine pregnancy test at screening for WOCBP.
- Ability of patient to understand and the willingness to sign a written informed
consent document
EXCLUSION CRITERIA:
- Patients with clinically unstable lesions (e.g., impending cord compression) where a
delay in receiving radiation therapy (XRT) would be detrimental are not eligible
- Current or prior anti-cancer treatment prior to the first dose of avelumab as defined
below:
- Chemotherapy, targeted small molecule therapy, or other anti-cancer treatment not
otherwise specified below within 2 weeks
- Radiation therapy within 2 weeks
- Anti-cancer monoclonal antibody (mAb) treatment within 4 weeks
- Use of an investigational agent (e.g., biologic, drug, or other) within 4 weeks
- Allogeneic stem cell transplant
- No autoimmune disease, as follows:
- Active (acute or chronic) autoimmune disease that might deteriorate when
receiving an immuno-stimulatory agent. Patients with type I diabetes, vitiligo,
psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive
treatment may be eligible.
- History of serious autoimmune-related disorders including immune colitis,
inflammatory bowel disease, pneumonitis, or pulmonary fibrosis whether drug-
mediated or not.
- Current use of immunosuppressive medication, EXCEPT for the following:
- Intranasal, inhaled, topical steroids, or local steroid injection (e.g.,
intra-articular injection)
- Systemic corticosteroids at physiologic doses
- Steroids as premedication for hypersensitivity reactions (e.g., CT scan
premedication)
- Uncontrolled intercurrent illness including, but not limited to the following that may
limit interpretation of results or that could increase risk to the patient in the
judgment of the investigator:
- Patients with a positive hepatitis B core antibody [HBcAb] and negative surface
antigen (HBsAg) may be included if hepatitis B virus (HBV) deoxyribonucleic acid
(DNA) is undetectable
- Patients who are positive for hepatitis C virus (HCV) antibody must be negative
for HCV by polymerase chain reaction (PCR) to be eligible for study participation
- Known acquired immunodeficiency syndrome (AIDS). Controlled and stable human
immunodeficiency virus (HIV) positivity is allowed
- Prior organ transplantation including allogenic stem-cell transplantation
- Clinically significant cardiovascular disease: cerebral vascular accident/stroke
(< 6 months prior to enrollment), myocardial infarction (< 6 months prior to
enrollment), unstable angina, congestive heart failure (greater than or equal to
New York Heart Association Classification Class III), or serious cardiac
arrhythmia requiring medication. Mild arrhythmias, e.g. stable atrial
fibrillation, may be allowed at the discretion of the investigator
- Active infection requiring systemic therapy (minor infections may be allowed at
the discretion of the investigator)
- Known mental or physical illness that would interfere with cooperation with the
requirements of the trial or confound the results or interpretation of the
results of the trial and, in the opinion of the treating investigator, would make
the patient inappropriate for entry into the study.
- Persisting toxicity related to prior therapy (Grade > 1); however, alopecia, sensory
neuropathy Grade less than or equal to 2, or other Grade less than or equal to 2 not
constituting a safety risk based on investigator s judgment are acceptable.
- Vaccination with live vaccines within 4 weeks of the first dose of avelumab and while
on study is prohibited (inactivated vaccines may be administered).
- Pregnant or lactating females. Because there is an unknown but potential risk for
adverse events in nursing infants, on-study breastfeeding is not allowed.
- History of allergic reactions or hypersensitivity to avelumab or any component in its
formulations, including known severe hypersensitivity reactions to monoclonal
antibodies (Grade greater than or equal to 3) unless felt to be in the best interests
of the patient at the discretion of the investigator.
- Known additional malignancy that is symptomatic or requires active systemic treatment
(at the discretion of the principal investigator (PI), exceptions may be made if in
the best interest of the patient).
- 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 study
participation or study treatment administration or may interfere with the
interpretation of study results and, in the judgment of the investigator, would make
the patient inappropriate for entry into this study.
