Scientific title
DANTE: A randomised phase III trial to evaluate the Duration of ANti-PD1 monoclonal antibody Treatment in patients with metastatic mElanoma
Acronym
DANTE
Study hypothesis
This trial aims to determine whether anti-PD1 monotherapy to treat advanced melanoma can be stopped after 1 year, rather than the current standard practice (i.e. continuing to treat until disease progression/unacceptable toxicity, or for at least 2 years), and achieve and maintain as good an outcome (in terms of the cancer coming back).
The hypothesis is that continuing treatment beyond 1 year is unnecessary, as there is no biological evidence that justifies continuous therapy; many responses occur in the first year and can continue even after treatment is stopped. Also, continuing treatment exposes patients to an increased risk of developing immune-related toxicities and is a considerable burden to patients and the National Health Service.

Condition
Metastatic melanoma
Intervention
Population: Patients with advanced (unresectable stage III or IV) melanoma who are due to start (or are within 12 months of starting) anti-PD1 monotherapy as their 1st line treatment
Consenting patients will be registered with the CTRU within the first 12 months of starting anti-PD1 monotherapy. The registration phase is not considered part of this clinical trial. Patients will receive anti-PD1 monotherapy and undergo monitoring and scans as per standard of care. When they are approaching 12 months of treatment, patients who have not progressed and remain on treatment will be approached for formal eligibility assessment and be consented for randomisation into the trial.
Baseline (pre-randomisation) assessments:
1. CT scan at 12 months post start of treatment (standard practice)
2. Quality of life and health economics questionnaire completion
Intervention: Stop anti-PD1 therapy at randomisation (12 months after starting therapy)
Comparator (control): Continue anti-PD1 therapy until disease progression or unacceptable toxicity (or a minimum of 2 years in the absence of progression/unacceptable toxicity)
Follow-up assessments
1. Every 3 months for the first 12 months post randomisation, then every 6 months in years 2 to 4 post-randomisation. A CT and/or MRI scan will be performed at each timepoint (standard practice)
2. Patients will complete quality of life and health economic questionnaires every 3 months until 18 months post-randomisation

Primary outcome measure
Progression-free survival is measured according to RECIST v1.1 at 12 months post-randomisation, using the pre-randomisation (12 month post-start of treatment) scan as the baseline
Secondary outcome measures
1. Quality of life is measured using the participant self-reported EORTC QLQ-C30, QLQ-MEL38 and the EQ-5D-5L questionnaires at baseline (pre-randomisation), 3, 6, 9, 12, 15 and 18 months post-randomisation (key secondary outcome)
2. Overall survival is calculated from the date of randomisation to the date of death from any cause, or the date last known to be alive for patients who are not known to have died
3. Objective response rate is measured according to RECIST v1.1 at 12 months post-randomisation of the final participant, using the pre-randomisation (12 month post-start of treatment) scan as the baseline
4. Best tumour response rate is measured according to RECIST v1.1 at 12 months post-randomisation of the final participant, using the pre-randomisation (12 month post-start of treatment) scan as the baseline
5. Duration of response is measured according to RECIST v1.1 at 12 months post-randomisation of the final participant, using the pre-randomisation (12 month post-start of treatment) scan as the baseline
6. Safety and toxicity is measured according to CTCAE v5.0 at 12 months and 4 years post-randomisation of the final participant
7. Cost-effectiveness is measured using the incremental cost effectiveness ratio (ICER) and compared against the NICE threshold of £20,000 per QALY. This will be done both within trial (using data collected to 18 months post-randomisation) and across patient lifetime using a Markov model (at 4 years post-randomisation of the final participant

Participant exclusion criteria
Exclusion criteria for RANDOMISATION
1. Severe comorbidities, including severe autoimmune disease or pneumonitis
2. Active infection requiring systemic therapy
3. Known history of HIV, hepatitis B or C
4. Other malignancy within past 5 years, excluding adequately treated Stage 1 or Stage 2 basal/squamous cell carcinoma of the skin, carcinoma in situ of the cervix or breast, or other in situ cancers
5. Pregnant, breast-feeding or patients with reproductive potential (female and male) unwilling to use adequate contraception while receiving anti-PD1 therapy and for 6 months after the last dose. Women of reproductive potential are defined as: following menarche and until becoming post-menopausal, unless permanently sterile. Men of reproductive potential are defined as: post-pubescent and not sterile by vasectomy or bilateral orchidectomy.
6. Prior systemic treatment for advanced melanoma, including ipilimumab and combination ipilimumab and nivolumab, other than BRAF and MEK inhibitors and the current treatment for advanced melanoma. Prior adjuvant or neo-adjuvant therapy is allowed as long as it was completed at least 12 months prior to starting anti-PD1 therapy
7. Treated brain metastases with MRI evidence of progression and/or requirement for high doses of systemic corticosteroids that could result in immunosuppression (> 10 mg/day prednisolone equivalents)
8. Untreated brain metastases that are symptomatic and/or require local intervention (surgery, radiosurgery, corticosteroid therapy) or other systemic therapy
