Chemotherapy with docetaxel has remained a cornerstone of second-line treatment for more than 15 years, but it is associated with an unfavorable safety profile. Recently, the results of 2 randomized phase III trials assessing nivolumab in lung cancer, Check-Mate-017 and Check- Mate-057, have deeply changed our current clinical practice and open the debate for further improvements in the clinical care of lung cancer. This paper explores the recent findings about nivolumab in the second-line setting and discusses future directions for nivolumab and other immune Oncology drugs.

ANTI-PD1 ROLE IN TREATMENT OF CUTANEOUS MELANOMA: The treatment of metastatic melanoma dramatically changed over the last years. Two therapeutic revolutions emerged in parallel, targeted anti-BRAF and anti-MEK therapies, for patients BRAFV600 mutated and immunotherapy with immune checkpoint blockers using anti-CTLA-4 then anti-PD1 monoclonal antibodies. Indeed, melanoma immunotherapy was a golden objective for many years but in spite of important efforts using cytokines (interferon, interleukin) and different vaccine approaches no objective improvement of patients 'prognosis was obtained. ⋯ Two molecules, pembrolizumab and nivolumab were recently approved in monotherapy, for metastatic melanoma. Several questions remain unresolved: the respective indications of anti-PD1 and targeted therapies in first line therapy in patients with BRAF mutant melanoma, the benefit of combining immunotherapy with radiotherapy or with targeted therapies, the optimal treatment duration, and the benefit of the anti-PD1 in the adjuvant setting. The combination of ipilimumab and nivolumab, recently approved by the FDA but not yet in Europ, shows an improvement of the objective response rates (50-57%) and progression free survival compared with nivolumab but is associated with an higer incidence of serious adverse events (more than 50%).
