Brief Summary
The purpose of this research project is to test the effectiveness of nivolumab versus nivolumab together with ipilimumab for the treatment of melanoma brain metastases. Patients are eligible to join this study if they are aged 18 years or above and have been diagnosed with melanoma with brain metastases.

Secondary Outcomes (11)
Extracranial response rate
Approximately 3 years
Overall response rate
Approximately 3 years
Progression free survival in intracranial disease

Up to 10 years
- +6 more secondary outcomes
Study Arms (3)
Cohort 1 Nivolumab Monotherapy
ACTIVE COMPARATORNivolumab 3mg/kg every 2 weeks, until disease progression, withdrawn consent, unacceptable toxicity or death. After 52 weeks, nivolumab dosing can change to 480mg every 4 weeks
Cohort 2 Nivolumab Monotherapy
ACTIVE COMPARATORNivolumab 3mg/kg every 2 weeks, until disease progression, withdrawn consent, unacceptable toxicity or death. After 52 weeks, nivolumab dosing can change to 480mg every 4 weeks
Cohort 3 Nivolumab and Ipilimumab
ACTIVE COMPARATORNivolumab 1mg/kg every 3 weeks x four doses and ipilimumab 3mg/kg every 3 weeks x four doses. After 12 weeks, nivolumab 3mg/kg alone every 2 weeks until disease progression, withdrawn consent, unacceptable toxicity or death. After 52 weeks, nivolumab dosing can change to 480mg every 4 weeks
Interventions
Nivolumab is a fully human monoclonal antibody directed against the negative immunoregulatory human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1/PCD-1) with immunopotentiation activity.
Ipilimumab is a recombinant, human monoclonal antibody that binds to the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activation. Ipilimumab binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation. The mechanism of action of ipilimumab's effect in patients with melanoma is indirect, possibly through T-cell mediated anti-tumour immune responses.
Eligibility Criteria
You may qualify if:
- ≥18 years of age.
- Written informed consent
- AJCC Stage IV (any T, any N, M1c) histologically confirmed melanoma or unknown primary melanoma. Patients must have at least 1 radiological definitive brain metastasis that is ≥ 5mm and ≤40mm measurable per RECIST version 1.1 guidelines.
- In patients with prior BRAF inhibitor treatment, intracranial disease progression must be demonstrated (RECIST \>20% or new measurable brain metastases) compared with nadir of intracranial response during BRAF inhibitor treatment, and confirmed with a second MRI brain scan at any time from the beginning of the drug washout period (dabrafenib=5 days, trametinib=14 days).
- No prior localised treatment for brain metastases (eg. surgery or radiotherapy).
- Neurologically asymptomatic from brain metastases.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2, and life expectancy \> 30 days.
- Able to undergo MRI with Gadolinium contrast agent.
- Adequate haematological, hepatic and renal organ function.
- Women of childbearing potential: negative serum pregnancy test and effective contraception from 14 days prior to study treatment until 23 weeks after the last dose.
- Men with female partner of childbearing potential to use effective contraception from 14 days prior to study treatment until 31 weeks after the last dose.
You may not qualify if:
- Any melanoma brain metastasis \>40mm.
- Ocular melanoma.
- Prior treatment with an anti-PD-1 or anti-PD-L1 , anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways.
- Patients with active, known or suspected autoimmune disease. Patients with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
- Current systemic treatment with corticosteroids, except prednisone at nonimmunosuppressive doses of ≤ 10 mg/day (or equivalent). Past treatment for non-neurological symptoms allowed, if ceased 2 weeks prior to starting study treatment. Inhaled or intranasal corticosteroids (with minimal systemic absorption) may be continued if patient on a stable dose. Non-absorbed intraarticular steroid injections will be permitted.
- Any investigational drug or other systemic drug therapy for melanoma within 28 days or 5 half-lives from baseline.
- Known to be HIV positive, or a positive test for hepatitis B and C .
- Another malignancy or concurrent malignancy unless disease-free for 3 years.
- Serious or unstable pre-existing medical conditions or other conditions that could interfere with the patient's safety, consent, or compliance.
- Pregnant or breastfeeding females.
- Administration of any form of live vaccination (such as influenza vaccine) within 30 days of starting trial and anticipated use during the trial. Administration of any other vaccine is cautionary within 30 days of starting the trial and during the trial.
- Cohort 2 - per Cohorts 1 \& 3, except patients must have at least one of the following:
- Failed prior local therapy for brain metastases (including surgery, stereotactic radiotherapy or whole brain radiotherapy) where disease has progressed per RECIST (\>20% increase in SOD or new measurable brain metastases),
- and/or;
- Have current neurological symptoms related to brain metastases. IF they have received prior local therapy for brain metastases, the disease must have progressed per RECIST (\>20% increase in SOD or new measurable brain metastases),
- +2 more criteria
