1. Histologically confirmed diagnosis of stage II (AJCCv8) melanoma arising from a
primary cutaneous site after surgery therapy. 2. Sentinel node biopsy (SNB) without detection of melanoma deposits. 3. Randomization not later than 12 weeks after SNB procedure. 4. Tumor tissue from primary tumor must be provided for biomarker analyses. In order to
be randomized, a subject must be classified by MelaGenix risk analysis.
5. Men and women at the age of 18 to 80 years. 6. Signed written, informed consent. 7. Patients must be willing and able to comply with scheduled visits, treatment schedule,
laboratory testing, and other requirements of the study. 8. Minimum life expectancy of five years excluding their melanoma diagnosis. 9. ECOG performance status of 0-1. 10. Screening laboratory values must meet the following criteria and should be obtained
within 14 days prior to randomization:
- - White blood cells (WBC) ≥ 2000/μL.
- - Platelets ≥ 100 x103/μL.
- - Serum creatinine ≤ 1.5xUL.
- - Creatinine clearance (CrCl) ≥ 40mL/min (using the Cockcroft-Gault formula)
- AST / ALT ≤ 3 x ULN.
- - Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who may have
total bilirubin < 3.0 mg/dL)
Negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent
units of HCG) for women of childbearing potential (WOCBP) within 72 hours prior to
Women will be considered to be of childbearing potential unless surgically sterilized
(hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), or being
post-menopausal for at least 24 months or being amenorrheic for > 12 months and
follicle-stimulating hormone (FSH) levels ≥ 40 IU/L.
12. WOCBP and male patients with partners of childbearing potential must agree to always
use a highly effective form of contraception according to CTFG during the course of
this study and for at least 5 months after last dose of study medication (in Arm A
1. History of primary uveal or mucosal melanoma. 2. No access to sufficient tumor tissue of primary tumor. 3. SNB procedure > 12 weeks before randomization. 4. Prior active malignancy within the previous 3 years except for locally curable cancers
that have been apparently cured, such as: basal or squamous cell skin cancer,
superficial bladder cancer or carcinoma in situ of the prostate, cervix, or breast.
Exception: Participants with a history of non-ulcerated cutaneous/acral primary
melanoma <1 mm in depth with no nodal involvement are allowed in this trial.
5. Prior or planned therapy with Interferon alpha, CTLA4 or PD-1 / PD L1 antibodies. 6. Use of any investigational or non-registered product (drug or vaccine) other than the
study treatment. 7. Administration of live vaccines within 4 weeks before start of study therapy. 8. Any immunosuppressive therapy given within the past 30 days. 9. Active psychiatric or addictive disorders that may compromise his/her ability to give
informed consent or to comply with the trial procedures. 10. Active immune deficiencies or significant autoimmune disease. 11. Serious cardiac, gastrointestinal, hepatic or pulmonary disease which would reduce
life expectancy to less than five years. 12. Serious intercurrent illness, requiring hospitalization. 13. Other serious illnesses, e.g., serious infections requiring antibiotics or bleeding
disorders. 14. The patient is known to be positive for Human Immunodeficiency Virus (HIV) or other
active chronic infections (HBV, HCV) or has another confirmed or suspected
immunosuppressive or immunodeficient condition. 15. Any serious or uncontrolled medical disorder that, in the opinion of the investigator,
may increase the risk associated with study participation or study drug
administration, impair the ability of the subject to receive protocol therapy, or
interfere with the interpretation of study results.
16. Hypersensitivity to the active substance or to any of the excipients. 17. Participation in another clinical study within the 30 days before registration. 18. For female patients: Pregnancy or breast-feeding. 19. For WOCBP and male patients with partners of childbearing potential: Refusal or
inability to use effective means of contraception. 20. Lack of availability for clinical follow-up assessments. 21. Legal incapacity or limited legal capacity
