title: A multi-center phase II study of nintedanib as second-line therapy for patients with advanced non-small-cell lung cancer in China.
abstract: OBJECTIVE
  This study examined the efficacy and safety of using nintedanib as single-regimen in 2(nd)-line chemotherapy for Chinese patients with advanced (beyond stage IIIB) non-small-cell lung cancer (NSCLC).
  
  
  METHODS
  Chinese patients were those with stage IIIB or IV NSCLC and had unsuccessful 1(st)-line platinum based chemotherapy. Patients received two oral intakes of 200 mg nintedanib everyday from day 1 to day 21, on every 4-week cycle. Primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS) and disease control rate.
  
  
  RESULTS
  There were 62 eligible patients enrolled in the study. Half of the patients were male (n = 31, 50.0%). The median age was 64.2 years with youngest age of 33 years and oldest age of 83 years. Median PFS was 3.9 months (95% CI, 2.7-6.4 months). Median OS was 6.7 months (95% CI, 4.8-10.1 months). No patients (0.0%) had complete response. Thirty-one patients (50.0%) had stable disease and 23 patients (37.1%) had partial response. The most common severe adverse events (AEs), graded as 3 or 4, were heart failure (n = 12, 19.4%), hypertension (n = 7, 11.8%) and diarrhea (n = 6, 9.8%).
  
  
  CONCLUSIONS
  NSCLC Patients in 2(nd)-line chemotherapy reached similar PFS, as compared with other FDA-approved second-line regimens. Also, the toxicity of nintedanib was well tolerated. Thus, nintedanib may be used as a standard regimen for 2(nd)-line chemotherapy for patients with advanced NSCLC.
