Background and study aims
We are looking for new and better ways to manage melanoma, an aggressive type of skin cancer. 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 bodies. At present, following surgery, patients with early-stage melanoma can either choose to have close monitoring with regular scans and skin checks or they can have a year of drug treatment. This study is testing whether we can follow patients with regular blood tests looking for DNA that comes from the cancer (ctDNA) and only treat those patients that become ctDNA positive, indicating cancer is still present. Critically, this test can identify early melanoma relapse when it is not visible on imaging. Thus, we can reduce the amount of unnecessary drug treatment and potential side effects for patients by using ctDNA testing. Patients will remain in the study for at least 5 years and will be seen in hospital clinics.
This is a feasibility study, which means that the researchers are looking at whether a large-scale study could be possible by first of all working with a smaller number of participants. They want to know if they can recruit enough patients in 12 months and analyse blood tests promptly. If it is feasible, they will then be looking to expand DETECTION-2 into a much larger Phase III study which will involve a larger number of participants to compare treatments.

Who can participate?
Patients over 16 years of age with resected stage IIB/IIC/IIIA, BRAF/NRAS/TERT promoter mutated cutaneous melanoma

What does the study involve?
Patients will be required to consent to the trial and have the correct mutation. They will then be randomly put into either a group to receive drug treatment as they would usually do in standard of care or to not receive drug treatment but instead have regular blood tests to monitor their ctDNA. The visit schedule for those receiving drug treatment will depend on the drug given. Those on ctDNA blood testing would be seen every 3 months in the first 3 years and every 6 months in years 4 and 5 to have a check-up and their blood taken for ctDNA. All patients will continue with routine standard-of-care scans (CT but maybe MRI or PET depending on local hospital policy). These would occur every 3 months in year 1, every 6 months in years 2 and 3, and then annually in years 4 and 5. If patients relapse during the trial or have a positive ctDNA test result they would be offered additional treatment according to local standard of care policies.

What are the possible benefits and risks of participating?
It is hoped that the treatment strategy will help patients but this cannot be guaranteed. Patients receiving standard-of-care drug treatment may benefit from this. They may also have potentially harmful side effects. Patients receiving ctDNA monitoring may benefit from not receiving drug treatment at that point and the potential harmful side effects as they will only receive drug treatment when the ctDNA test suggests they have a higher risk of relapse. There is a small chance that the cancer might not be picked up early by the blood test but the treatments we give in melanoma work very well even at this time. Patients receiving drug treatment will have more visits at the start of the study than those on ctDNA monitoring. The information from this study may help improve the future treatments for patients with stage IIB/IIC/IIIA melanoma.

Where is the study run from?
The study is being run by the Southampton Clinical Trials Unit at the University of Southampton, in collaboration with The Christie NHS Foundation Trust (sponsor) and the University of Manchester (UK)

Study acronymDETECTION-2
Study objectivesSurgery 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 bodies. At present, following surgery, patients with early-stage melanoma can either choose to have close monitoring with regular scans and skin checks or they can have a year of drug treatment. This study is testing whether we can follow patients with regular ctDNA (circulating tumour DNA found in the blood) tests and only treat those patients that become ctDNA positive indicating disease activation. Thus reduce the amount of unnecessary drug treatment and potential side effects for patients by using ctDNA testing. This test can identify early melanoma relapse when it is not visible on imaging.

Health condition(s) or problem(s) studiedSkin cancer
InterventionPre-screening:
Potentially eligible patients will provide consent for their tumour sample (already obtained for diagnosis) to be sent to the Manchester Centre for Genomic Medicine to undergo mutational analysis. Patients whose tumour has a confirmed mutation (called BRAF, NRAS or TERT) will be eligible to proceed. Depending on the sites local patient pathways, patients can consent to the pre-screening first and the main study at a later date, or consent to the main study immediately.

Screening:
If not already done, patients will provide consent for the main study and undergo screening assessments including a physical examination, review of medical history, and a CT scan (which may have already been done). If all eligibility criteria are met, the patient may be randomised.

Randomisation:
Participants will be randomised at a ratio of 1:1 to either Arm A (standard of care adjuvant treatment) or Arm B (treatment based on regular monitoring of circulating tumour DNA [ctDNA]).

Arm A:
Participants will discuss their standard of care adjuvant treatment options with their doctor and proceed with 1 year of treatment, followed by 4 more years of follow-up. Visit frequency during the treatment phase will depend upon the treatment given. After treatment, patients will continue to be followed up as per the protocol schedule (designed to match standard of care). CT scans will be completed as per the protocol, designed to match standard of care. Any standard of care assessments before, during and after treatment will continue (e.g. blood tests, pregnancy tests, ECGs) and symptom-led physical exams and disease assessments will be completed at each visit. If the cancer returns, patients will proceed with standard-of-care treatment.

Arm B:
Participants will have a baseline blood sample collected for ctDNA analysis at the National Biomarker Centre in Manchester, and again at each visit, as per the protocol schedule (which matches Arm A) for a total of 5 years. Sites are expected to send ctDNA samples on the day of collection and ctDNA test results will be returned to the site within 10 working days of sample collection. CT scans will be completed as per the protocol, designed to match standard of care. Any standard-of-care assessments will continue (e.g. blood tests, pregnancy tests, ECGs) and symptom-led physical exams and disease assessments will be completed at each visit.

ctDNA test outcomes:
1. Negative ctDNA result (ctDNA not detected) - participant continues with ctDNA monitoring
2. Positive ctDNA result (ctDNA detected) - participant will discuss standard of care treatment options and proceed with treatment
3. Uninformative ctDNA result - occasionally a test may need to be re-done due to strict quality assurance processes at the NBC laboratory.
If there is a local relapse of the cancer (with negative ctDNA result), the participant will undergo surgery to remove the cancer and may continue with ctDNA monitoring. If there is distant relapse, the participant will cease ctDNA monitoring and proceed with standard of care treatment as per their discussions with their doctor.
- Visit schedule for both Arm A & B

The visit schedule has been designed to best match standard of care follow-up for this patient group.
Year 1: 3-monthly visits (months 3, 6, 9 and 12) - (Arm A patients will also have treatment visits as per standard care. The number of visits will depend on the treatment)
Year 2: 3-monthly visits (months 15, 18, 21 and 24)
Year 3: 3-monthly visits (months 27, 30, 33 and 36)
Year 4: 6-monthly visits (months 42 and 48)
Year 5: 6-monthly visits (months 54 and 60)

CT scans:
CT scan frequency is designed to match standard of care as best as possible. Scans will be 3-monthly until 12 months, then 6-monthly until 36 months, then annually until 60 months. Brain scans (CT or MRI) will be completed 6-monthly until 36 months, then annually until 60 months.

Data collection:
To minimise the burden on sites, data collection will occur via an annual minimal eCRF that will collect details of cancer treatments, adverse events, relapse event data, CT scan details, concomitant medications and ECOG score (the worst score recorded over the previous 12 months). In addition, for Arm B participants, the research team will need to enter the date of collection, date of receipt of result, and test result for each ctDNA blood test.
Intervention typeOther
Primary outcome measure1. Recruitment rate assessed by a randomised patient count following a recruitment period of 12 months (aim is for ≥50 patients randomised)
2. The proportion of ctDNA results returned to site ≤10 working days from the sample being taken (aim is for this proportion to be 95% or above)
Secondary outcome measures1. Relapse-free survival (RFS) defined as time from randomisation to radiological or clinical (confirmed histologically) relapse or death from any cause
2. Distant metastatic-free survival (DMFS) defined as time from randomisation to radiological distant metastatic relapse or death from any cause
3. Overall survival (OS) defined as the time from randomisation to death from any cause
4. Time from randomisation in Arm B to detection of ctDNA for those patients who had a ctDNA positive result
5. The number of patients in Arm B with undetectable ctDNA (according to the DETECTION-2 assay) but with clinical/radiological relapse and site of relapse (local or distant in addition to organ site) over the course of the trial
