Comparison of lorlatinib, alectinib and brigatinib in ALK inhibitor–naive/untreated ALK-positive advanced non-small-cell lung cancer: a systematic review and network meta-analysis

Because of lacking of head-to-head comparison among lorlatinib, alectinib and brigatinib for patients with ALK inhibitor–naive or untreated (ALK inhibitor-naive and chemotherapy-naive) ALK-positive advanced non-small-cell lung cancer (NSCLC), the optimal option for these patients still remains undefined. We searched published reports that described the activity and safety of those novel ALK inhibitors (lorlatinib, alectinib and brigatinib) for ALK inhibitor–naive or untreated (ALK inhibitor-naive and chemotherapy-naive) ALK-positive advanced NSCLC. Five randomized controlled trials were identified, covering 1111 subjects. In the network meta-analysis, lorlatinib seemed to prolong progression free survival than brigatinib (Hazard Ratio: 0.57, P = 0.03) and alectinib (Hazard ratio: 0.65, P = 0.05) for previously untreated patients with ALK-positive advanced NSCLC as assessed by the independent review committee. Meanwhile, lorlatinib significantly improved significant progression free sur..... READ ARTICLE

EP114-07 Efficacy and Safety of ALK Inhibitors in ALK-Rearranged Non-Small Cell Lung Cancer: A Systematic Review and Meta-Analysis

We conducted a systematic review and meta-analysis to assess the efficacy and safety of ALK inhibitors compared to chemotherapy (ALK vs. chemo) and 2nd generation ALK inhibitors compared to 1st generation ALK inhibitors (ALK 2G vs. ALK 1G).The electronic databases PubMed and EMBASE, were searched for relevant randomized trials. Pooled hazard ratios (HR) for overall survival (OS) and progression free survival (PFS), and pooled risk ratios for objective response rates (ORR) and grade 3 or higher toxicity were meta-analyzed using the generic inverse variance and the Mantel-Haenszel methods. To account for between-studies heterogeneity, random-effect models were used. Subgroup analyses compared PFS by gender, smoking status, brain metastases, race and age.This meta-analysis is the first, to our knowledge, to report an OS improvement with the use of ALK vs. chemo. A trend toward a better OS was also seen with ALK 2G vs. ALK 1G and this is likely because of crossover effects and limited OS f..... READ ARTICLE
