About this trial
The goal of this clinical trial is to investigate adaptive therapy in late-stage cutaneous melanoma. The main question it aims to answer are:
If the patient having breaks in their treatment allows the less resistant cells to continue to grow, this would result in a tumour with a lower proportion of resistant cells, making the tumour less resistant to the treatment, an increasing the time it takes for the disease to progress?
Participants will
* Receive their allocated treatment regimen until their cancer progresses, they or their doctor withdraw them from the study, or until the study ends, whichever happens first. * Attend fortnightly visits to hospital. * Complete EORTC QLQ-C30 and PRO-CTCAE questionnaires, prior to treatment, every 12 weeks and at the point of cancer progression, to assess quality of life.
Researchers will compare the adaptive therapy participant arm with a standard of care arm to answer the research question described above.

Treatments tested in this trial
Adaptive Therapy
DrugA blood test that measures the amount of tumour DNA circulating in the patient's blood (known as ctDNA) will be conducted every two weeks to check if the cancer cells are still present, and if they are becoming active. The result of this test will allow doctors to monitor the activity of the tumour and judge when to pause and resume encorafenib and binimetinib treatment. This intermittent treatment is called 'adaptive therapy'.
Standard of Care
DrugEncorafenib and binimetinib delivered to UK standard of care.
Treatment groups
Trial outcomes
Primary outcomes
To measure tumour response to re-introduction of encorafenib plus binimetinib following the first "drug off " period.
Specific measure: Maximal reduction in percentage ctDNA mutant BRAF copies/ml of plasma from baseline 2 TAB level upon restart of E+B following first drug off period.
Secondary outcomes
To measure the thresholds of percentage reduction in TAB level in ctDNA as a measure of response to stop drugs and the percentage increase in TAB as a decision to restart drugs.
Specific measure: ctDNA mutant BRAF copies/ml of plasma
To measure maximal response (complete response (CR)/partial response (PR)/stable disease (SD)/progressive disease (PD)) to therapy in Arm A vs. Arm B
Specific measure: Maximal radiological response (complete response (CR)/partial response (PR)/stable disease (SD)/progressive disease (PD)) using RECIST v1.1 criteria
To measure progression free survival (PFS) in Arm A vs. Arm B
Specific measure: Percentage of participants who have experienced disease progression or death. PFS defined as time from randomisation to radiological (RECIST v1.1 and in Arm B defined as radiological progression whilst on targeted therapy unless stopped due to toxicity/choice) progression
To measure time to clinical deterioration in Arm A vs. Arm B.
Specific measure:Time to clinical deterioration. Defined as either the point of radiological progression (defined as per RECIST v1.1) or in participants treated beyond radiological progression, at the time of clinically determined deterioration defined at the discretion of the treating clinician, specifically due to progression of the underlying cancer
