The principal investigator of the ORIENT-31 Study, Prof. Shun Lu from the Oncology Department of Shanghai Chest Hospital, stated, “Different from the western population, about half of the Chinese patients with NSCLC have EGFR mutations. EGFR-TKI targeted therapy is the first line treatment choice in NSCLC patients with EGFR sensitive mutation. However, almost all patients will eventually develop TKI-resistance and progression of disease and there are no good treatment options for EGFR-TKI failed NSCLC population[iii]. The ORIENT-31 study is globally the first prospective, randomized and double-blind Phase 3 study that demonstrated that PD-1 inhibitor ± bevacizumab combined with chemotherapy can significantly prolong PFS in EGFR-mutant non-squamous NSCLC population who have failed EGFR-TKI treatment. In addition, compared with standard platinum-based chemotherapy, sintilimab and bevacizumab combined with chemotherapy improved the ORR and DOR, showing survival benefit trend as well as improvement in quality of life. The approval of this indication brings a new treatment option for EGFR-mutated non-squamous NSCLC patients who have failed EGFR-TKI treatment, benefiting more Chinese patients.”
