De-escalation Immunotherapy mAintenance Duration Trial for Stage IV Lung Cancer Patients With Disease Control After Chemo-immunotherapy Induction
Immunotherapeutic approaches recently have demonstrated clinical efficacy in several cancer types, including melanoma and NSCLC. As a matter of fact, first registration trials of immune-checkpoints inhibitors (ICI) in second-line settings (pembrolizumab as well as nivolumab or atezolizumab) had stated that ICI could be continued until disease progression or not tolerable toxicity, up to 5 years. This is only for the first-line registration studies that the arbitrary maximal duration of treatment of 2 years was set up by the Companies sponsoring such trials.
The aim is to study a de-escalation
