Nivolumab +/- Ipilimumab in Patients With Advanced, Refractory Pulmonary or Gastroenteropancreatic Poorly Differentiated Neuroendocrine Tumors (NECs) (NIPINEC)

A GCO Trial Exploring the Efficacy and Safety of Nivolumab Monotherapy or Nivolumab Plus Ipilimumab in Pre-treated Patients With Advanced, Refractory Pulmonary or Gastroenteropancreatic Poorly Differentiated Neuroendocrine Tumors (NECs)

Neuroendocrine tumors of the lung include the small cell carcinoma (SCLC), and large cell neuroendocrine carcinoma (LCNEC) and represent 20% of lung cancer. One of the only studies reported to date is reporting on a progression-free survival (PFS) and overall survival (OS) of 5.2 months and 7.7 months, respectively.

Poorly differentiated gastroentero-pancreatic neuroendocrine carcinomas (GEP-NEC) represent a small sub-group of digestive NENs, according to the studies, 7 to 21% of patients. However, their prognosis is more negative, with the 5-year survival at less than 20%.

Many Phase III trials showed superiority in terms of efficacy and tolerance of nivolumab+/-ipilimumab versus standard chemotherapy in second-line treatment in metastatic solid tumors. Neuroendocrine tumors are considered as rare disease without therapeutic guidelines in this setting. The French academic oncology groups (IFCT, FFCD and GERCOR) have the opportunity to recruit a sufficient number of patients, in a reasonable period of time, to provide a proof-of-concept of the safety and efficacy of nivolumab+/-ipilimumab in this population.

Poorly differentiated neuroendocrine carcinoma (NEC): large and small cells for gastroenteropancreatic NEC (WHO 2010 classification) and only large cells for lung NEC (WHO 2015 classification), independently from PD-L1 expression status by tumor cells; mixed tumors with a prominent (>70%) NEC component are eligible

9. Patients must have recovered from all toxicities associated with prior treatment, to acceptable baseline status, or a National Cancer Institute Common Terminology Criteria for Adverse Events(NCI CTCAE v4.0) Grade of 0 or 1, except for toxicities not considered a safety risk, such as alopecia or vitiligo

13. Females of childbearing potential who are sexually active with a non-sterilized male partner must use a highly effective method of contraception for 28 days prior to the first dose of investigational product, and must agree to continue using such precautions for 6 months after the final dose of investigational product; cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. They must also refrain from egg cell donation for 6 months after the final dose of investigational product. Men receiving nivolumab and who are sexually active with women of childbearing potential will be instructed to adhere to contraception for a period of 31 weeks after the last dose of nivolumab.
14. Patient must be affiliated to or a beneficiary of social security insurance.

Exclusion Criteria:

1. Patients <18 years old

Patients with history of solid tumors, including adenocarcinoma, treated in a curative way with or without chemotherapy and without any evidence of disease >2 years before randomisation can be included as well.
