NCT03520634 : PD-L1 PET Imaging in Melanoma Patients
AgesMin: 18 Years Max: N/A
Inclusion Criteria:

1. Subjects must sign informed consent prior to inclusion in this trial.

2. Subjects must be =18 years of age and competent to give informed consent.

3. Subjects must be diagnosed with histologically confirmed stage IV melanoma.

4. At least one radiologic new lesion in the brain by MRI, which should be measurable by
RANO-BM criteria (longest diameter = 10 mm and perpendicular diameter = 5 mm). Lesions
with prior local treatment (i.e., SRT or surgical resection) can be considered
measurable if there has been demonstrated progression since the time of local
treatment. Leptomeningeal involvement is allowed, but cannot be used as target lesion.

5. At least one easy accessible metastatic melanoma lesion of which a biopsy can be

6. Subjects must be treatment-naive to nivolumab. (also as adjuvant treatment)

7. Subjects must score at least 1 or higher on the Eastern Cooperative Oncology Group
(ECOG) Performance Status.(21)

8. Subjects must have adequate organ function as defined by the following laboratory
values (determined within 28 days prior to randomization/registration):

- White blood cells (WBC) = 2000 /µL

- Absolute neutrophil count (ANC) = 1500 /µL

- Platelets = 100 x103 /µL

- Hemoglobin = 9 g/dL or = 5.6 mmol/L

- Serum creatinine = 1.5 times upper limit of normal (ULN) or creatinine clearance
> 40 ml/min (using the Cockcroft-Gault formula)

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) = 3 times ULN

- Bilirubin = 1.5 times ULN (Except patients with the Gilbert Syndrome, for whom a
maximum of = 3.0 mg/dL is acceptable)

9. Women of childbearing potential (WOCBP) should have a negative urine or serum
pregnancy test within 7 days prior to receiving the first administration of nivolumab.
Women with non-childbearing potential may be included if they are either surgically
sterile or have been postmenopausal for = 1 year.

10. WOCBP and men who are sexually active with WOCBP must agree to use appropriate
method(s) of contraception. (see section 5.2)

Exclusion Criteria:

1. Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2 antibody, or any other
antibody or drug specifically targeting T-cell costimulation or immune checkpoint
pathways, except anti-CTLA4 antibody.

2. Subjects who have not recovered to Common Terminology Criteria for Adverse Events
(CTCAE) v4.0 Grade 1 or better from the adverse events due to previous cancer therapy.

3. Evidence for an active, known or suspected autoimmune disease. Subjects diagnosed with
vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune
condition only requiring hormone replacement, psoriasis not requiring systemic
treatment, or conditions not expected to recur in the absence of an external trigger
are permitted to enroll.

4. Treatment with corticosteroids in an increasing dosage in the 7 days prior to the
first administration of nivolumab. (A stable or decreasing dosage of = 4 mg
dexamethasone or equivalent is allowed. In addition, inhaled or topical steroids and
adrenal replacement doses are permitted in the absence of active autoimmune disease.)

5. Previous malignancies (except non-melanoma skin cancers, in situ bladder cancer,
gastric or colon cancers, cervical cancers/dysplasia or breast carcinoma in situ)
unless a complete remission was achieved at least 1 years prior to study entry and no
additional therapy is required or anticipated to be required during the study period.

6. A severe hypersensitivity reaction to prior treatment with a monoclonal antibody, or
known hypersensitivity to study drugs components.

7. A positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus
ribonucleic acid (HCV antibody) indicating acute or chronic infection.

8. Known history of testing positive for human immunodeficiency virus (HIV) or known
acquired immunodeficiency syndrome (AIDS).

9. Any serious or uncontrolled medical disorder or active infection that, in the opinion
of the investigator, may increase the risk associated with study participation, study
drug administration, or would impair the ability of the patients to receive protocol

10. A known psychiatric or substance abuse disorder that could interfere with cancer

11. Women of childbearing potential with a positive serum or urine pregnancy test (minimum
sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of

12. Breastfeeding women.

13. Inability to comply with other requirements of the protocol.
