RESUMEN
Dual inhibition of vascular endothelial growth factor and epidermal growth factor receptor (EGFR) signaling pathways offers the prospect of improving the effectiveness of EFGR-targeted therapy. In this phase 3 study (ClinicalTrial.gov: NCT04028778), 315 patients with treatment-naïve, EGFR-mutated, advanced non-small cell lung cancer (NSCLC) were randomized (1:1) to receive anlotinib or placebo plus gefitinib once daily on days 1-14 per a 3-week cycle. At the prespecified final analysis of progression-free survival (PFS), a significant improvement in PFS was observed for the anlotinib arm over the placebo arm (hazards ratio [HR] = 0.64, 95% CI, 0.48-0.80, P = 0.003). Particularly, patients with brain metastasis and those harboring EGFR amplification or high tumor mutation load gained significant more benefits in PFS from gefitinib plus anlotinib. The incidence of grade 3 or higher treatment-emergent adverse events was 49.7% of the patients receiving gefitinib plus anlotinib versus 31.0% of the patients receiving gefitinib plus placebo. Anlotinib plus gefitinib significantly improves PFS in patients with treatment-naïve, EGFR-mutated, advanced NSCLC, with a manageable safety profile.

BACKGROUND: : Phase II-III trials in patients with untreated and previously treated locally advanced or non-small cell lung cancer (NSCLC) suggested that Endostar was able to enhance the effect of platinum-based chemotherapy (NP regimen) with tolerable adverse effects. METHODS: Four hundred and eighty six patients were randomized into two arms: study arm A: NP plus Endostar (n = 322; vinorelbine, cisplatin, Endostar), and study arm B: NP plus placebo (n = 164; vinorelbine, cisplatin, 0.9% sodium chloride). Patients were treated every third week for two to six cycles. RESULTS: : Overall response rates were 35.4% in arm A and 19.5% in arm B (P = 0.0003). The median time to progression was 6.3 months for arm A and 3.6 months for B, respectively (P < 0.001). The clinical benefit rates were 73.3% in arm A and 64.0% in arm B (P = 0.035). Grade 3/4 neutropenia, anemia, and nausea/vomiting were 28.5%, 3.4%, and 8.0%, respectively, in Arm A compared with 28.2%, 3.0%, and 6.6%, respectively, in Arm B (P > 0.05). There were two treatment related deaths in arm A and one in arm B (P > 0.05). The median overall survival was longer in arm A than in arm B (P < 0.0001). CONCLUSION: : Long-term follow-up revealed that the addition of Endostar to an NP regimen can result in a significant clinical and survival benefit in advanced NSCLC patients, compared with NP alone.
