Technical Field

The invention belongs to the field of medicines, and relates to application of a human Epidermal Growth Factor Receptor Inhibitor (EGFRI) and a chemotherapeutic drug in preparation of a drug for preventing or treating non-small cell lung cancer (NSCLC).

Background

Worldwide, lung cancer has become the leading cause of cancer death, both morbidity and mortality are on the rise, with about 180 new lung cancer cases worldwide in 2012, and 210 thousands of lung cancer diagnosis cases worldwide by 2018. In China, from the aspect of morbidity, the statistical data of the Chinese cancer center shows that lung cancer is the first to occur nationwide, the lung cancer occurs about 78.1 ten thousand every year, and the lung cancer accounts for 20.55 percent of the weight of various types of cancers; from the aspect of mortality, lung cancer, liver cancer, stomach cancer and esophageal cancer are the main causes of death of tumors. Despite the recent generations of cytotoxic drugs and targeted therapies that have been introduced over the last 20 years, patients with advanced lung cancer, particularly those who do not have known driver mutations or develop resistance after treatment with EGFR inhibitors, have poor treatment options and prognosis of survival, and advanced or metastatic lung cancer remains a fatal disease with an unmet medical need.

Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers, with about 75% of NSCLC patients found in the middle-to late stage with a very low 5-year survival rate. There is still a great clinical need to select an appropriate systemic treatment for patients with advanced or metastatic NSCLC. NSCLC can be further classified as squamous cell carcinoma and non-squamous cell carcinoma. Non-squamous cell carcinomas include adenocarcinomas, large cell carcinomas and other subtypes of cell carcinoma. Non-squamous cell carcinoma patients are further classified according to the presence or absence of the driver mutant gene (EGFR mutation, ROS1 mutation, or ALK gene rearrangement).

Egfr (epidemal Growth Factor receptor) is a member of the erbB receptor family of transmembrane protein tyrosine kinases. EGFR can form homodimers on cell membranes by binding to its ligand, e.g., Epidermal Growth Factor (EGF), or heterodimers with other receptors in the family, such as erbB2, erbB3, or erbB 4. The formation of these dimers can lead to phosphorylation of key tyrosine residues in EGFR cells, thereby activating multiple downstream signaling pathways in the cells. These intracellular signaling pathways play important roles in cell proliferation, survival, and resistance to apoptosis. Dysregulation of the EGFR signaling pathway, including increased expression of ligands and receptors, EGFR gene amplification and mutation, can promote cellular transformation to malignancy, and play an important role in proliferation, invasion, metastasis and angiogenesis of tumor cells. Overexpression of EGFR has been reported in a number of human malignancies, including bladder, brain, head and neck, pancreatic, lung, breast, ovarian, colon, prostate, and kidney cancers. In many cases, overexpression of EGFR is associated with poor prognosis in patients.

At present, four main basic treatment methods for lung cancer are available, namely surgery, radiotherapy, chemotherapy and targeted treatment. The optimal treatment means is different for different stages of lung cancer with different pathological types. With the gradual and deep understanding of disease biology, pathogenesis and the functions of proto-oncogene mutation in the process of generating and developing tumors, the targeted EGFR inhibitor represented by Gefitinib brings unprecedented survival benefit to non-small cell lung cancer patients containing EGFR mutation. The method has the advantages of remarkably improving the objective response rate, the disease-free development survival time, the toxic and side effects of the medicine and the like compared with the prior chemotherapy. However, both first-generation EGFR inhibitors, represented by Gefitnib, second-generation EGFR inhibitors, represented by Afatinib, and third-generation EGFR inhibitors, represented by osimertinib (AZD9291), develop drug resistance in non-small cell lung cancer patients after long-term clinical use. Currently, there is no good clinical treatment for the above patients who develop resistance. Therefore, the improvement of the clinical curative effect of the existing treatment scheme or the delay of the clinical drug resistance of the EGFR inhibitor is particularly important for improving the survival period and the prognosis of the non-small cell lung cancer patients.

Example 1 evaluation of the Experimental therapeutic Effect of Almonertib in combination with chemotherapeutic drugs (Pemetrexed and cisplatin) on human Lung cancer PC-9 nude mouse transplantable tumors

1. Experimental Material

Almonertinib was prepared according to the method disclosed in WO2016054987 using a pH4.18 acetate buffer for pharmaceutical formulations.

Pemetrexed and cisplatin, supplied by Jiangsu Haisen pharmaceutical industry group, Inc.

PC-9 cells (containing an EGFR Del19 deletion) were purchased from Biotech, Inc., Ginie, Guangzhou. 150cm2Culturing in adherent culture bottle under the conditions of RPMI1640 medium supplemented with 10% fetal calf serum and 1% streptomycin/penicillin at 37 deg.C and 5% CO2Air incubator. Carrying out 1-2 passages in one week, when the cells are in exponential growth phase, carrying out pancreatin digestion, collecting the cells, counting and inoculating.

Nude mice, female; at 6-8 weeks, 80 inoculates, 54 practical uses, and the unit is Shanghai Sphere-BiKai laboratory animals Co., Ltd

2. Experimental methods

Will be 5X 106Injecting human lung cancer cell PC-9 into the subcutaneous part of the right upper back of the nude mouse until the tumor grows to the average volume of 150-3Thereafter, the animals were grouped according to tumor volume (D0). Gavage (p.o) mice, 1 time daily (QD), or intraperitoneal injection (i.p), 1 time weekly (QW); the administration volume is 10 mL/kg; solvent group administration phaseThe same volume of "solvent" (pH 4.18 acetate buffer); the specific dosage and administration schedule are shown in table 1 and table 2. Tumor volume was measured, mouse body weight was weighed and data was recorded.

The experimental index is to examine the influence of the drug on the tumor growth, and the specific index is T/C% or tumor inhibition rate TGI (%).

The tumor diameter is measured by a vernier caliper, and the tumor volume (V) is calculated by the formula:

V=1/2×a×b2wherein a and b represent length and width, respectively.

T/C(%)=(T-T0)/(C-C0) X 100 wherein: t, C is the tumor volume at the end of the experiment, T0、C0Tumor volume at the beginning of the experiment.

Tumor inhibition rate (TGI) (%) 100-T/C (%).

When tumors regress, tumor inhibition rate (TGI) (%) 100- (T-T)0)/T0×100

If the tumor is reduced from the initial volume, i.e. T<T0Or C<C0When, it is defined as partial tumor regression (PR); if the tumor completely disappears, it is defined as complete tumor regression (CR).

The experiment is finished, the experimental end point is reached, or the tumor volume reaches 2000mm3,CO2The sacrifice was anesthetized.

The experimental data were analyzed and plotted using GraphPad Prism 6.0. Two groups of tumor volumes were compared using a two-tailed T-test. Three or more groups were compared using one-way ANOVArepeated measures, and if there were significant differences in F-values, multiple comparisons should be made using Dunnett's after ANOVA analysis. P <0.05 was defined as statistically significant.
