Background: Cisplatin-based chemoradiotherapy is the standard treatment for unresectable, locally advanced non-small-cell lung cancer (NSCLC). This trial evaluated two experimental regimens that combine chemotherapy with concurrent radiotherapy., Methods: Eligible patients with unresectable stage III NSCLC were randomised to either the SP arm (S-1 and cisplatin) or VP arm (vinorelbine and cisplatin), with early concurrent thoracic radiotherapy of 60 Gy, comprising 2 Gy per daily fraction. The primary endpoint was the overall survival rate at 2 years (2-year overall survival (OS)) (Study ID: UMIN000002420)., Results: From September 2009 to September 2012, 112 patients were enroled. Of the 108 eligible patients, the 2-year OS was 75.6% (80% confidence interval (CI), 67-82%) in the SP arm and 68.5% (80% CI: 60-76%) in the VP arm. The hazard ratio (HR) for death between the two arms was 0.85 (0.48-1.49). The median progression-free survival was 14.8 months for the SP arm and 12.3 months for the VP arm with an HR of 0.92 (0.58-1.44). There were four treatment-related deaths in the SP arm and five in the VP arm., Conclusions: The null hypotheses for 2-year OS were rejected in both arms. The West Japan Oncology Group will employ the SP arm as the investigational arm in a future phase III study.

Background: This phase Ib study evaluated afatinib plus vinorelbine in patients with advanced solid tumours overexpressing epidermal growth factor receptor (EGFR) and/or human EGFR 2 (HER2)., Methods: Maximum tolerated doses (MTDs) were determined for afatinib (20, 40 or 50 mg, once daily) combined with standard intravenous vinorelbine (part A; 25 mg m -2 per week) or oral vinorelbine (part B; 60 mg m -2 per week, increased to 80 mg m -2 per week at week 3). Secondary end points for expanded MTD cohorts included assessments of safety, pharmacokinetics, tumour response and progression-free survival (PFS)., Results: The afatinib MTD was 40 mg with intravenous (MTD A ) and oral (MTD B ) vinorelbine. The most frequent cycle 1 dose-limiting toxicities were febrile neutropenia and diarrhoea, consistent with individual safety profiles of vinorelbine and afatinib. Common treatment-related adverse events included: diarrhoea (92.7%), asthenia (76.4%), nausea (63.6%), neutropenia (56.4%) and vomiting (54.5%). No notable pharmacokinetic interactions were observed. Best overall tumour response was stable disease in part A (16 out of 28 patients), and partial response in part B (3 out of 27 patients). Median PFS was 14.6 and 15.9 weeks for patients treated at the MTD A and MTD B , including dose-escalation and expansion cohorts., Conclusions: Afatinib in combination with intravenous or oral vinorelbine demonstrated a manageable safety profile and antitumour activity at the MTD of 40 mg per day.
