Brief summary: Lung cancer is the second most common malignancy and mortality rate in the world. In the United States and Europe, approximately 10% to 15% of NSCLC patients have epidermal growth factor receptor (EGFR)-sensitive mutations, with higher mutation rates of 30% to 40% in Asia, and objective response rates (ORRs) of 76% to 80% with EGFR Tyrosine Kinase Inhibitor (TKI)-targeted therapy. However, resistance mechanisms such as EGFR, MET, PIK3CA and BRAF gene alterations occur with the development of resistance to EGFR-TKI therapy; Median Progression Free Survival (mPFS) for only 2.8-3.2 months; The median overall survival (mOS) is only 7.5-10.6 months. Due to the variety of mechanisms of resistance to EGFR-TKIs and the limited efficacy of chemotherapy, it is necessary to provide salvage treatment for advanced non-small cell lung cancer that is positive for EGFR-sensitive mutations and has failed EGFR TKIs.

Anlotinib is a novel multi-target tyrosine kinase inhibitor (TKI) used to inhibit tumor angiogenesis and proliferative signaling. The main targets of anlotinib include tyrosine kinase vascular endothelial growth factor receptor 1-3 (VEGFr1-3), fibroblast growth factor receptor 1-4 (Fibroblast Growth Factor Receptor 1-4), platelet-β derived growth factor receptor α and β, and stem cell factor receptor. Anlotinib is rapidly absorbed through the intestine, has high bioavailability, a half-life of 5 days, and is convenient for oral administration, which is conducive to improving patient dependence. IN MAY 2018, THE CHINA FOOD AND DRUG ADMINISTRATION APPROVED ANLOTINIB FOR MARKETING, ENTERED THE MEDICAL INSURANCE CATALOG IN OCTOBER OF THE SAME YEAR, AND WAS RECOMMENDED BY THE CHINESE SOCIETY OF CLINICAL ONCOLOGY (CSCO) FOR THE THIRD-LINE TREATMENT OF LUNG CANCER IN 2019.

Penpulimab is a humanized immunoglobulin G1 monoclonal antibody (IgG1), which is a class 1 new drug jointly developed by Zhongshan Akeso Biopharmaceutical Co., Ltd. and Chia Tai Tianqing Pharmaceutical Group Co., Ltd., which can specifically bind to PD-1 molecules on the surface of T lymphocytes, thereby blocking the PD-1/PD-L1 pathway that leads to tumor immune tolerance, and reactivating the anti-tumor activity of T lymphocytes to achieve the purpose of treating tumors. A number of preclinical in vitro trials have verified the effect of PEAMPLIMAB in blocking PD-1 pathway, and the results of preclinical pharmacodynamics, animal pharmacokinetics and toxicology have shown that PEAMPLIMAB has good stability, reduced host cell protein residues, and can effectively bind to antigens, and eliminate Fc-mediated effector function, with higher safety.

AK105-201 is a multicenter, double-blind, randomized controlled, phase III clinical trial evaluating the efficacy and safety of pianpulimab combined with carboplatin + paclitaxel in the first-line treatment of locally advanced or metastatic squamous non-small cell lung cancer, the primary endpoint of the study was PFS, and the secondary endpoint was OS, and the results showed that the mPFS group of pianpulimab and the control group were 7.6m and 4.2m, respectively, and the HR was 0.44, reducing the risk of disease progression by 56%. In the 2022 CSCO guidelines for the diagnosis and treatment of non-small cell lung cancer, peamplimab combined with platinum-containing chemotherapy is recommended as the first-line treatment for stage IV driver-free squamous cell carcinoma Grade II. In advanced patients with EGFR TKIs resistance, pemetrexed chemotherapy has a good efficacy, with a median PFS of 2.83 months and a response rate of 22%. The AK105-203 study is a multicenter phase II clinical study led by Professors Jiao Shun and Bai Li of the Chinese PLA General Hospital of the People's Liberation Army of Anlotinib combined with péamplimab in the first-line treatment of hepatocellular carcinoma, with a median follow-up of 23 months and mPFS of 8.8 months.

Therefore, based on the results of the current study on immunosuppressants and antiangiogenic drugs for the treatment of NSCLC, and the current research status in patients with advanced NSCLC who are positive for EGFR-sensitive mutations and have failed EGFR TKIs, we expect to conduct an exploratory clinical study of PD-1 antibody (péamplimab) combined with anlotinib in patients with advanced NSCLC who are positive for EGFR-sensitive mutations and have failed EGFR TKIs, with the aim of evaluating the safety of this combination, It was further investigated whether this combination could further improve the survival benefit of patients with advanced NSCLC.

Detailed description: Non-small cell lung cancer is the most common type of lung cancer, accounting for 80%-85% of all lung cancers, and about 57% of patients with advanced NSCLC have distant metastases at the time of diagnosis, although chemotherapy, targeted therapy and anti-angiogenic drugs have become the cornerstone of the treatment of advanced NSCLC, but the emergence of immune checkpoint inhibitors in recent years has changed the treatment model of NSCLC. Immune checkpoint inhibitors enhance the body's antitumor activity by inhibiting the immune escape mechanism of tumors, and prolong the survival time of NSCLC patients. According to statistics, the 5-year survival rate of NSCLC patients who join immunotherapy and undergo multi-line therapy can reach 16%.

Previous studies have confirmed that anti-angiogenic drugs and immunotherapy have the effect of improving tumor microenvironment, basic translational and clinical studies have shown that immune checkpoint inhibitors and anti-angiogenic drugs have a synergistic effect, anti-angiogenic drugs can exert immunosuppressive effects by preventing immune invasion of tumors through tissue remodeling and fibrosis, and patients can benefit from PD-1/PD-L1 inhibitors combined with anti-angiogenic therapy.

In the CheckMate 057 and KEYNOTE-001 studies, the ORRs of patients with advanced NSCLC treated with anti-PD-1 monotherapy were 19% (mPFS 2.3 months) and 19.4% (mFS 3.7 months), respectively. The results of Wangpl et al. demonstrated that anti-PD-1 combined with anlotinib in the treatment of advanced NSCLC had an ORR of 28.4%, a DCR of 86.6%, and an mPFS of 6.9 months (95% CI, 5.5-8.3 months), confirming that the combination therapy of anlotinib and anti-PD-1 drugs has a good efficacy and can be used as a second- or third-line treatment in previously treated patients with advanced NSCLC, indicating VEGF-VEGFR2 and PD-1-/ The dual inhibition of the PD-L1 pathway has clinical applicability.
