Study Description

Brief Summary:

In this phase II advanced melanoma study, all patients will receive treatment with nivolumab/ipilimumab plus cabozantinib for a 12 week induction period followed by nivolumab plus cabozantinib maintanence to complete up to 2 years of therapy unless disease progression, dose limiting toxicity, provider/patient decision or patient withdrawal of consent occurs. The primary endpoint is the one year PFS rate. Patients will have staging scans at baseline and every 12 weeks during the first 2 years on study. Safety evaluations including labs, EKG and history and physical will occur at each visit. Baseline tumor sample is required and on treatment biopsy will be optional of superficial tumor in the skin, subcutaneous tissue or lymph node that is palpable.

Condition or disease	Intervention/treatment	Phase
Melanoma	Drug: Nivolumab; Drug: Ipilimumab; Drug: Cabozantinib	Phase 2

Detailed Description:

Subjects will receive nivolumab, ipilimumab and cabozantinib until either disease progression, the occurrence of unacceptable drug-related toxicity or for other reason(s) for subject withdrawal. Treatment will continue for up to 2 years unless there is disease progression, drug intolerance or other reason for discontinuation discussed with the principal investigator (PI). Patients with ongoing complete or partial response may discontinue therapy after 1 year on treatment at the discretion of the treating investigator.

Outcome Measures

Primary Outcome Measures :

1. The progression free survival (PFS) for nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 1 year ]
   The PFS rate for nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma using imRECIST.

Secondary Outcome Measures :

1. The response rate of nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 1 year ]
   The ORR by imRECIST of nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma.
2. The overall survival (OS) of patients with unresectable advanced melanoma treated with nivolumab/ipilimumab plus cabozantinib. [ Time Frame: 3 years ]
   The median and 3 year OS rate of patients with unresectable advanced melanoma treated with nivolumab/ipilimumab plus cabozantinib.
3. The incidence of treatment-emergent adverse events of nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 2 years ]
   The rate of all grade and grade 3-5 adverse events and the rate of discontinuation of study drug(s) due to adverse events.

Other Outcome Measures:

1. Associations between baseline tumor mutational burden (TMB), angiogenesis pathways, and immunophenotyping with clinical activity of nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 3 years ]
   Measured in terms of ORR, PFS, and OS.
2. Associations between baseline mutations in genes regulating anti-tumor immunity with tumor immunophenotype and clinical activity of nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 3 years ]
   Measured in terms of ORR, PFS, and OS.
3. On treatment biopsy for evidence of increased immune infiltration, vascularization, and MHC expression to nivolumab/ipilimumab plus cabozantinib in patients with unresectable advanced melanoma. [ Time Frame: 1 year ]
   Measured by the change in immune cell populations, CD31 vascularization, and MHC class I expression by multiplex immunofluorescense (IF) between baseline and on treatment tumor specimens.

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All

2. Age > 18 and ECOG Performance Status of 0 or 1.
3. Measurable disease by RECIST 1.1 and a tumor site amenable for on treatment biopsy.
4. Baseline tumor specimen available.
5. Recovery to baseline or ≤ Grade 1 CTCAE v4 from toxicities related to any prior treatments, unless AE(s) are clinically nonsignificant and/or stable on supportive therapy.

Eligible subjects must be neurologically asymptomatic and without corticosteroid requirement.

   Allowed anticoagulants are the following:

   1. Low-dose aspirin for cardioprotection (per local applicable guidelines) is permitted.
   2. Low-dose low molecular weight heparins (LMWH) are permitted.
   3. Anticoagulation with therapeutic doses of LMWH is allowed in subjects without known brain metastases who are on a stable dose of LMWH for at least 6 weeks before first dose of study treatment, and who have had no clinically significant hemorrhagic complications from the anticoagulation regimen or the tumor.
8. The subject has prothrombin time (PT)/INR or partial thromboplastin time (PTT) test ≥ 1.3 x the laboratory ULN within 7 days before the first dose of study treatment.
9. The subject has uncontrolled, significant intercurrent or recent illness.
10. Major surgery (eg, GI surgery, removal or biopsy of brain metastasis) within 8 weeks before first dose of study treatment.

14. Previously identified allergy or hypersensitivity to components of the study treatment formulations.
15. Diagnosis of another malignancy within 2 years before first dose of study treatment, except for superficial skin cancers, or localized, low grade tumors deemed cured and not treated with systemic therapy.
16. Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids, and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
