Dual blockade of EGFR and VEGFR pathways: Results from a pilot study evaluating apatinib plus gefitinib as a first-line treatment for advanced EGFR-mutant non-small cell lung cancer.

ABSTRACT:

Background

Dual blockade of both EGFR and VEGFR pathways in EGFR-mutant NSCLC have shown enhanced antitumor efficacy versus EGFR-TKIs alone. Apatinib is an orally effective VEGFR-2 tyrosine kinase inhibitor (TKI). This pilot study aims to evaluate the tolerability, pharmacokinetic profile, and antitumor activity of apatinib plus gefitinib as a therapy for EGFR-mutant advanced NSCLC.

Methods

Advanced non-squamous NSCLC participants harbored with the EGFR 19 deletion or the 21 L858R point mutation were included. There were two cohorts: Cohort A: apatinib 500 mg + gefitinib 250 mg. Cohort B: apatinib 250 mg + gefitinib 250 mg. The primary endpoint was safety profile. Other endpoints consisted of PK analysis, objective response rate (ORR), and progression-free survival (PFS).
