Phase III clinical trial - Appareil pulmonaire
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.
