      Introduction

      There is renewed interest in the efficacy of 2nd line treatments (2LT) with anti-angiogenics (AA), now that immunotherapy plus chemotherapy (CT) is one of the standard options in 1st line treatment of advanced non-small cell lung cancer (NSCLC). Antibodies (mAb) against VEGF, VEGFR2, or AA tyrosine kinase inhibitors (TKI) have inconsistently shown benefit in combination with CT or erlotinib (E). We performed an individual patient data (IPD) meta-analysis to validate efficacy of these combinations as 2LT.

      Methods

      Randomized trials of AA plus standard 2LT (CT or TKI) compared to 2LT alone that ended accrual before 2015 were identified from publication databases, abstract proceedings and trial registers. Fixed-effect models were used to compute pooled hazard ratios (HRs) for overall survival (OS, primary endpoint), progression-free survival (PFS) and subgroup analyses. Peto method was used to estimate survival benefit.

      Results

      IPD were available for 15 out of 17 eligible trials (only via remote access for 9 trials). Out of 8,502 patients (pts) enrolled, 35% were female and 64% had adenocarcinoma. At 3 years, 10.5% were alive. Addition of AA significantly prolonged OS (HR=0.93 [95% confidence interval (CI): 0.89-0.98], p=0.005) and PFS (0.80 [0.77-0.84], p<0.0001) compared with 2LT alone. Absolute 1-year OS and PFS benefit for AA were +1.9% [95% CI: -0.3%;+4.1%] and +3.6% [+2.0%;+5.2%] respectively. According to the 3 types of combinations (mAb AA + CT, TKI AA + CT, AA + E), there was no significant interaction for OS. Interaction was significant for PFS (p=0.004): HR=0.78 [0.72-0.85], 0.86 [0.80-0.91] and 0.70 [0.63-0.77] respectively. There was a significant reduction of AA benefit on OS when age increased: 0.86 [0.75-0.99], 0.89 [0.81-0.97], 0.94 [0.87-1.02] and 1.04 [0.93-1.17] for pts <50, 50-59, 60-69 and ≥70 respectively (interaction p=0.009). Effect of AA was independent of sex (p=0.98) and performance status (0, ≥1; p=0.78) and ethnicity (Asian, non-Asian, p=0.38). Subgroup results were similar for PFS.

      Conclusion

      In the 2LT of advanced NSCLC, adding AA modestly but significantly prolongs OS and PFS. This appears independent of type of AA drugs, but the observed benefit may be higher in younger pts.
