Brief summary

This is a single arm open-label design study looking at Nivolumab plus Ipilimumab in patients with Advanced Neuroendocrine Tumors. Patients will be dosed Nivolumab 240mg IV over 60 minutes every 2 weeks (Q2W) and Ipilimumab 1mg/kg IV over 30 minutes every 6 weeks (Q6W). One cycle will include 3 doses of Nivolumab and 1 dose of Ipilimumab. The objective of this study is to evaluate the objective response rate of combination Nivolumab and Ipilimumab in advanced, well-differentiated neuroendocrine tumors. Durability of response, and progression free survival (PFS) will also be described.

Detailed description

Subjects with progressive, non-functional advanced or metastatic thoracic, GI or pancreatic well-differentiated neuroendocrine tumors (NET) have few treatment options. The only FDA approved treatment regimen offers little response potential. In currently unpublished data with inhibitory immune checkpoint agents, patients with NET have shown promising clinical benefit. This therapy offers a novel approach to potentially provide long term benefit, but must be further explored. The safety profile of nivolumab plus ipilimumab is characterized by immune-related toxicities, such as diarrhea, rash, pneumonitis, liver toxicity, and endocrinopathies (Nivolumab, Ipilimumab Investigator's Brochures). The frequencies and intensities of these events in the combination are variable and depend on the specific doses and schedule used. In the dosing schedules selected, these events were mostly low grade and manageable with the use of corticosteroids. Nivolumab and ipilimumab combination therapy has shown improved efficacy over either agent alone in melanoma. Rationale for Single Arm Design This study will use a single arm open-label design. The objective of this study is to evaluate the objective response rate of combination nivolumab and ipilimumab in advanced, well-differentiated neuroendocrine tumors. Durability of response, and PFS will also be described.

Inclusion criteria

* Subjects with histologically confirmed advanced, progressive, well-differentiated nonfunctional NET of the pancreas, lung or gastrointestinal (GI) tract per the 8th International Association for the Study of Lung Cancer classification (IASLC) or the American Joint Committee on Cancer (AJCC) Staging Handbook, 7th edition. Progression must be documented over the prior 12 months. * Measurable disease by CT or MRI per RECIST 1.1 criteria (Appendix 3); radiographic tumor assessment performed within 28 days before treatment. Target lesions may be located in a previously irradiated field if there is documented (radiographic) disease progression in that site after the completion of radiation therapy. * Prior therapy, including everolimus, octreotide, surgery, chemoradiation, is all permitted after being properly noted. This prior therapy must have been completed at least 28 days prior to study enrollment. * Patients with lung NETs must have progressed after at least 1 line of therapy. Patients with GI NETs must have had at least 2 lines of prior therapy. * Subjects are to have tumor tissue sample available at central lab for programmed cell death ligand 1 (PD-L1) immunohistochemistry (IHC) testing during the screening period. Subjects can initiate therapy before the result of IHC testing. * (Stage 2 only) Subjects must be willing to undergo 2 sets of core needle biopsies (pre-treatment and at 6-8 weeks on therapy) if there are lesions amenable to biopsy. Subjects without a lesion amendable to biopsy will still be permitted to enroll provided they have an archival tumor sample for PD-L1 IHC testing. An optional core biopsy will be requested at progression. * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 (see Appendix 1) * Prior palliative radiotherapy to non-central nervous system (CNS) lesions must have been completed at least 2 weeks prior to treatment. Subjects with symptomatic tumor lesions at baseline that may require palliative radiotherapy within 4 weeks of first treatment are strongly encouraged to receive palliative radiotherapy prior to treatment. * Patients must have normal organ and marrow function as defined below: * \- white blood cell (WBC) ≥1,500/microliters (mcL) * \- absolute neutrophil count ≥1,000/mcL * \- hemoglobin ≥ 8.0 g/dL * \- platelets ≥75,000/mcL * \- total bilirubin ≤ 1.5 x institutional ULN (patients with Gilbert's syndrome may have serum bilirubin ≤ 3 x ULN) * \- aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 3 × institutional ULN (≤ 5 x ULN in the presence of liver metastases) \- creatinine * ≤ 1.5 × institutional ULN or creatinine clearance (CrCl) ≥ 40 mL/min (if using the Cockcroft-Gault formula below): * Female: * CrCl = (140 - age in years) x weight in kg x 0.85 o 72 x serum creatinine in mg/dL * Male: * CrCl = (140 - age in years) x weight in kg x 1.00 \- 72 x serum creatinine in mg/dL * Age ≥18 years of age * Patients must have recovered from adverse events due to prior treatment to ≤ grade 1, except for alopecia and sensory neuropathy ≤ grade 2. * Patients must be able to understand and the willingness to sign a written informed consent document. *

Exclusion criteria

* Subjects with poorly differentiated or small cell carcinoma histology * Subjects with disease that is amenable to surgical resection. * Subjects with history of or active symptoms of carcinoid or hormonal syndromes are permitted if symptoms are controlled with a somatostatin analog. * Hepatic intra-arterial embolization or peptide receptor radionuclide therapy (PRRT) within 4-8 weeks; cryoablation, radiofrequency ablation or trans-arterial chemoembolization of hepatic metastases within ≤ 4 weeks of study enrollment * Subjects with symptomatic untreated CNS metastases are excluded. * Subjects are eligible if CNS metastases are asymptomatic or adequately treated and subjects are neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 2 weeks prior to first treatment. * In addition, subjects must be either off corticosteroids, or on a stable or decreasing dose of \<10 mg daily prednisone (or equivalent) for at least 2 weeks prior to first treatment. * Subjects with carcinomatous meningitis * Subjects must have recovered from the effects of major surgery or significant traumatic injury at least 14 days before first treatment. * Pregnant or breast-feeding women * Women of child-bearing potential, who are biologically able to conceive, and not employing two forms of highly effective contraception. Highly effective contraception must be used throughout the trial and up to 8 weeks after the last dose of study drug (e.g. male condom with spermicidal; diaphragm with spermicide; intra-uterine device). Women of child-bearing potential, defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months), must have a negative serum pregnancy test ≤ 14 days prior to starting study drug. * Subjects with an active, known or suspected autoimmune disease. Subjects with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll. * Other active malignancy requiring concurrent intervention. * Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of first treatment.

Objective Response Rate (ORR) of Neuroendocrine Tumor (NET) of the Lung, Pancreas, and Gastrointestinal (GI) Tract

The number of subjects who have at least one scan with an Objective Response (OR) of confirmed complete response (CR) or partial response (PR), per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions as assessed by CT scan: Objective Response (OR), a response of CR or PR from baseline to PD, palliative local therapy, or subsequent anticancer therapy; Complete Response (CR), the disappearance of all target lesions and any pathological lymph nodes (target or non-target) with reduction in short axis to \<10 mm; Partial Response (PR), \>= 30% decrease in the sum of the longest diameters of target lesions, compared to baseline sum diameters

Time frame: up to 24 months

Population: One patient passed away during cycle 1 of therapy, from unrelated issue (colitis, not related to study drug) prior to first RECIST scans, thus was not assessable for ORR, DCR or DOR.
