The trial is looking for new and better ways to treat melanoma, an aggressive type of skin cancer. Having surgery to remove the melanoma will cure the majority of patients with early stage disease. However, a small percentage of these patients will go on to develop further disease, which may spread to other places in their body.

Currently, patients who have been cured of melanoma will have appointments in clinic to check that further disease has not developed or returned and some may also receive regular scans.

The trial team has developed a blood test that tells us whether cancer cells are still present or is becoming active after a patient has been 'cured' of melanoma, even if a scan looks normal. The test looks for pieces of DNA in the blood that are known to have come from the cancer, which we call 'circulating tumour DNA', or ctDNA. Patients who have ctDNA in their blood have an extremely high chance of the cancer returning.

By using the blood test that we have developed we think that we can identify patients earlier than normal. We think that some of the treatments that are used when melanoma cancer has spread may benefit patients at this earlier stage.

We want to see if these patients with ctDNA in their blood, who have a higher risk of their cancer returning or spreading, and receive treatment early have a better response to their cancer compared to those patients who receive treatment when their cancer has returned and it can be seen on a scan. This could mean we would be able to offer patients earlier treatment in the future using just a blood test rather than a scan, while also providing reassurance to those patients that do not have ctDNA in their blood that they do not need treatment and their cancer is not returning.

Complete resection (including SNLB) must have been performed within 12 weeks prior to registration
Disease-free status documented both clinically and radiologically within 4 weeks prior to registration
Mutation confirmed in at least one of the following BRAF (p.V600E/p.V600K/p.V600R) /NRAS (p.Q61R/p.Q61K, p.Q61L/p.G12D), which can be tracked in ctDNA with exact point mutation known
ECOG performance status 0/1
Adequate organ function and screening laboratory values must meet the following criteria: WBC 2.0x109/L, Absolute neutrophil count (ANC) 1.5x109/L, Platelets 100 x109/L, Haemoglobin 90 g/L, Creatinine 1.5x ULN or creatinine clearance >30mL/minute using Cockcroft-Gault, AST 1.5 x ULN, ALT 1.5 x ULN, Bilirubin 1.5 x ULN unless the patient has familial hyperbilirubinaemia
LDH 1.5x ULN as per local institution parameters
Patients who are pregnant or breastfeeding will be eligible to join the trial. However, if they are allocated to Arm B, women of childbearing potential (WOCBP) must agree to have a serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) and must be withdrawn if pregnant or breastfeeding. WOCBP and males who are sexually active with WOCBP must also agree to follow instructions for method(s) of contraception for the duration of treatment plus 5 months for WOCBP or plus 7 months for males who are sexually active with WOCBP (if randomised to Arm B or while receiving any systemic treatment and to follow local guidance if given on Arm A). See Appendix A for further information

Exclusion Criteria

If previously received prior immunotherapy, chemotherapy, cancer directed vaccine therapy or BRAF/MEK targeted therapy for cancer
Patients with active, known or suspected autoimmune disease. Patients with type 1 diabetes mellitus, rheumatoid arthritis not requiring disease modifying drugs, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger will be permitted to enrol
Current other malignancy or history of another malignancy within the last 3 years. Patients who have been disease-free for 3 years, (i.e. patients with second malignancies that have been definitively treated at least 3 years ago) or patients with a history of completely resected non-melanoma skin cancer are eligible
Any serious or unstable pre-existing medical conditions (aside from malignancy exceptions specified above), psychiatric disorders, or other conditions that could interfere with the patient's safety, obtaining informed consent, or compliance with study procedures
Patients with a condition requiring ongoing/long-term (>3 months) systemic treatment with either corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications. Inhaled or topical steroids and adrenal replacement steroid doses 10 mg daily prednisolone equivalent are permitted in the absence of active autoimmune disease
Patients with interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity
History of allergies or adverse drug reaction to any of the study drug components or to any monoclonal antibody
Known Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection
Prisoners or patients who are involuntarily incarcerated
