• Health condition(s) or Problem(s) studied: advanced non-small-cell lung cancer
• Date of first enrollment: 01/07/2019
• Target sample size: 172
• Study type: Interventional

Intervention(s)

Arm A (Standard arm): Continue the treatment including anti-PD-1 or anti-PD-L1 inihibitor treated before enrollment.

Outcome(s)

• Primary Outcome: overall survival
• Secondary Outcome: progression-free survival, time to failure of strategy, adverse events, serious adverse events, response rate of patients who restarted anti-PD-1 or anti-PD-L1 inhibitors (calculated for those allocated to arm B), and progression-free survival of patients who restarted anti-PD-1 or anti-PD-L1 inhibitors (calculated for those allocated to arm B)
