This clinical trial (ChiCTR1800019185) is designed to be an open‐label, prospective, single‐center, single arm exploratory research study. The study will recruit non‐small cell lung cancer patients (NSCLC) with slow progression after first‐line treatment with EGFR‐TKI drugs. Slow progression will be confirmed by the presence of serum carcinoembryonic antigen or imaging evaluation. The primary aim is to assess progression‐free survival after EGFR‐TKIs treatment combined with apatinib 250 mg once daily. The secondary objectives are to evaluate objective efficacy, disease control rates, quality of life, overall survival, and safety. From September 2018 to September 2020, under specific entry and discharge standards, we plan to enroll 38 eligible patients until the end of the study. We hope that our study will help to explore a new way of combining the small molecular inhibitors of antiangiogenesis with EGFR‐TKIs to overcome acquired drug resistance.
