Non Small Cell lung cancer (NSCLC) remains the first cause of death by cancer in the World. For the patients presenting a NSCLC stage IV, the median of survival is about 15 months today. The chemotherapy with platinum is the standard treatment for these patients but immunotherapy showed these efficacy in 1st line for patients PD-L1 positive. On the other hand, the duration of treatment by immunotherapy is not clear. Indeed, prolonged responses and long survivals have been described in patients having interrupted the treatment. In the melanoma, a treatment of 6 months of ipilimumab demonstrated its efficacy. The objective of the study is to demonstrate that a treatment of 6 months followed by an observation (stop and go) is not less effective than a treatment given until progression or toxicity. This strategy would allow to decrease the accumulated toxicities, to improve the quality of life of the patients and to decrease the costs.

Inclusion Criteria

Signed Written Informed Consent
Subjects must have signed and dated an IRB/IEC approved written informed
consent form in accordance with regulatory and institutional guidelines. This
must be obtained before the performance of any protocol related procedures
that are not part of normal subject care
Subjects must be willing and able to comply with scheduled visits, treatment
schedule, and laboratory testing
\. Histologically-proven NSCLC (squamous or non-squamous)
\. Stage IV (M1, including M1a pleural involvement) disease (8th
classification TNM, UICC 2015)
\. ECOG PS < 1
\. Weight loss< 10% in previous 3 months
\. No prior systemic anticancer therapy (including EGFR or ALK inhibitors)
given as primary therapy for advanced or metastatic disease
\. Age 18 years, <75 years
\. Life expectancy > 3 months
\. Measurable tumor disease by CT or MRI per RECIST 1.1 criteria
\. Available tumor samples for centralized PD-L1 immunohistochemistry
\. PD-L1 tumor content 1% and < 50% tumor cells as assessed locally by the
investigator center
\. Adequate biological functions
Creatinine Clearance 50 mL/min (Cockcroft or MDRD or CKD-epi); neutrophiles
mm3 ; platelets 100 000/mm3 ; Hemoglobin 9g/dL ; hepatic enzymes < 3x
ULN, total bilirubin 1,5 x ULN except for patients with proved, Gilbert
syndrome ( 5 x ULN) or patients with hepatic metastases ( 3,0 mg/dL)
\. Women of childbearing potential (WOCBP) and sexually active should use an
efficacious contraception method within the 28 days preceding the first dose
and during the 6 months following the last dose of treatment. Women must have
a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or
equivalent units of HCG) within 24 hours prior to the start of study drug
For Male subjects who are sexually active with WOCBP, an efficacious
contraception method should be used during the treatment and during the 7
months following the last dose
Investigators shall counsel WOCBP and male subjects who are sexually active
with WOCBP on the importance of pregnancy prevention and the implications of
an unexpected pregnancy. Investigators shall advise WOCBP and male subjects
who are sexually active with WOCBP on the use of highly effective methods of
contraception. Highly effective methods of contraception have a failure rate
of < 1% when used consistently and correctly. At a minimum, subjects must
agree to the use of two methods of contraception, with one method being highly
effective and the other method being either highly effective or less
\. Patient inclusion validated by a multidisciplinary meeting

Exclusion Criteria

Thoracic radiotherapy needed at initiation of tumor treatment, except bone palliative radiotherapy on a painful or compressive metastasis, respecting 4 weeks delay between the end of radiotherapy and the beginning of induction immunotherapy treatment
Symptomatic untreated brain metastasis (without previous whole brain radiotherapy or stereotactic ablative brain radiotherapy or without surgical resection). At least 4 weeks delay between the end of radiotherapy and the beginning of induction immunotherapy treatment should be respected.

Active inflammatory intestinal disease (diverticulosis, Crohn disease, Hemorrhagic recto-colitis, coeliac disease) or any serious chronic intestinal disease with uncontrolled diarrhea
Active uncontrolled infection including tuberculosis, known acute viral hepatitis B and C according to serological tests. Patients with serological sequelae of cured viral hepatitis are allowed to be included
HIV known infection
Living attenuated vaccine received within the 30 previous days
Previous treatment with anti-PD-1, anti-PD-L1 or Anti-CTLA4 antibody
Previous treatment with chemotherapy
