About

The primary objective of this clinical trial is to evaluate the clinical efficacy and progression free survival of the triplet combination of ipilimumab + nivolumab + cabozantinib in patients with anti-PD-1/PD-L1 refractory metastatic cutaneous melanoma.

Full description

This is a phase II, single arm, single institution clinical trial. Eligible adults with anti-PD-1 refractory, unresectable/metastatic cutaneous melanoma will be treated with the triplet combination of ipilimumab 1 mg/kg + nivolumab 3 mg/kg every 3 weeks for 4 cycles in addition to cabozantinib 40 mg/day. For cycles 5+, treatment will consist of nivolumab 480 mg IV every 4 weeks in combination with cabozantinib 40 mg/day. The total duration of therapy will be 24 months or until either disease progression or the occurrence of unacceptable drug-related toxicity. Regular tumor assessments should be performed to determine if PD is present.

Prior therapy:
1. Must have been treated previously with an immune checkpoint inhibitor targeting PD-1 or PD-L1.
2. Disease progression following treatment with prior anti-PD-1/PD-L1 therapy must be confirmed at least 4 weeks after the first imaging showing disease progression to rule out pseudoprogression.
3. Prior therapy with BRAF/MEK inhibitors (before or after anti-PD-1(L1) therapy) is allowed but not required.
4. Patients who develop unresectable/metastatic disease while receiving or following completion of adjuvant systemic anti-PD-1/PD-L1 therapy are eligible.

1. At least 1 lesion of ≥1.0 cm in the longest diameter for a non-lymph node or >1.5 cm in the short-axis diameter for a lymph node metastasis that is serially measurable according to iRECIST using computed tomography/magnetic resonance imaging (CT/MRI).
