Pharmaceutical composition and use thereof Technical Field
The present invention relates to a pharmaceutical composition comprising a therapeutically effective amount of furmonertinib or a pharmaceutically acceptable salt thereof and optionally a pharmaceutically acceptable carrier. The present invention also relates to use of furmonertinib or a pharmaceutically acceptable salt thereof, and the pharmaceutical composition in manufacture of a medicament for treating and/or preventing a disease mediated by PACC mutation (one subgroup of EGFR mutations, mutation on the interior surface of the ATP-binding pocket or C-terminal end of theαC-helix, which also referred as P-loop andαC-helix compressing mutation) . The present invention also provides a method of treating and/or preventing a disease mediated by PACC mutation, comprising administering to a patient a therapeutically effective amount of furmonertinib or a pharmaceutically acceptable salt thereof.
Background Technology
Worldwide, lung cancer has always been a malignant tumor with the highest morbidity and mortality and serious harm to human health and life, and 1.76 million people died of lung cancer in 2018 all over the world. Non-small cell lung cancer (NSCLC) comprises approximately 80-85%of all lung cancers. Epidermal Growth Factor Receptor (EGFR) is a multifunctional glycoprotein widely distributed on the cell membrane of various tissues of the human body. The EGFR mutation is the most widely studied target in NSCLC.
Among EGFR mutations, common mutations include sensitive mutations (such as exon 19 deletion and exon 21 point mutation (L858R) , comprising 85%-90%of all EGFR mutations) , drug resistant mutations (such as exon 20 T790M mutation, exon 20 C797S mutation) , etc. By using hierarchical clustering of in vitro selectivity over WT EGFR and mutational mapping of EGFR mutations, Robichaux etc. observed four distinct  subgroups of EGFR mutations: classical-like mutations that were distant from the ATP-binding pocket, T790M-like mutations in the hydrophobic core, insertions in the loop at the C-terminal end of theαC-helix in exon 20, and mutations on the interior surface of the ATP-binding pocket or C-terminal end of theαC-helix, which were predicted to be P-loop andαC-helix compressing (PACC) . PACC mutations include mutations spanning exons 18-21 including G719X, L747X, S768I, L792X, E709X, L718X, G724S, V769X and T854I, etc (Nature, volume 597, pages 732–737 (2021) ) .
Over the years, a large number of targeted drugs have been developed for EGFR mutation in NSCLC, such as the first generation of reversible tyrosinase inhibitor (TKI) Gefitinib and Erlotinib for EGFR sensitive mutation, the second generation of irreversible covalent binding inhibitor Afatinib, and the third generation of inhibitor Osimertinib for drug resistant mutation EGFR T790M, which have very good clinical effects.
However, no drug targeting EGFR PACC mutations has been approved in worldwide, so there is still a need to continue developing an effective, stable and safe small molecule drug as EGFR PACC mutation inhibitor.
N- {2- { [2- (dimethylamino) ethyl] (methyl) amino} -6- (2, 2, 2-trifluoroethoxy) -5- { [4- (1-methyl-1H-indol-3-yl) pyrimidin-2-yl] amino} pyridin-3-yl} acrylamide (also referred to as "furmonertinib" ) represented by the following formula (I) is described in patent CN105315259B, and the mesilate of the compound represented by the following formula (I) (also referred to as "furmonertinib mesilate" ) is described in patent CN107163026B, and furmonertinib mesilate has been commercialized as a third-generation EGFR-TKI inhibitor, and is mainly used for treating a disease mediated by EGFR-sensitive mutation and T790M drug-resistant mutation. The phase I rising study of furmonertinib mesilate demonstrates that when furmonertinib mesilate is orally taken once per day at a dosage level of20 mg-240 mg, the tolerance and the safety are good, adverse events of subjects are mild or moderate, dose-limiting toxicity does not occur, and dose-related toxic reaction does not occur; and in addition, the phase IIb clinical trial has demonstrated that the oral  administration of 80 mg daily dose of furmonertinib mesilate shows a relatively good anti-tumor effect on patients with the EGFR T790M positive advanced non-small cell lung cancer, who has progressive disease after receiving prior systematic anti-tumor therapy, and can alleviate or stabilize the disease progression.

This study was used for evaluate the anti-tumor efficacy of furmonertinib mesilate in the female (B-NDG) immune deficiency mice bearing tumors of Ba/F3 EGFR-G724S engineered cells.
Experimental animals: B-NDG mice, female, 6-8 weeks, and weighing 18-20g.
Animal modeling and random grouping: Ba/F3 EGFR-G724S cells were cultivated, cells were collected, and re-suspended and counted in serum-free medium, the re-suspended cells with the addition of a matrigel at 1: 1 were subcutaneous inoculated at 1×106 cells/0.1mL in B-NDG mice. When the average tumor volume was about 80-120 mm3, the animals were randomly grouped into four experiment groups according to the tumor size. Each group contained 12 mice. The grouping day was defined as Day 0, i.e., D0.
The experimental scheme: B-NDG mice were subcutaneously inoculated with Ba/F3 EGFR-G724S cells to establish a cell-line-derived xenograft model. The experiment was divided into 15 mg/kg group of furmonertinib mesilate, 30 mg/kg group of furmonertinib mesilate, 50 mg/kg group of furmonertinib mesilate and vehicle group, wherein each group contained 12 animals, orally administered with the administration volume of 10uL/g, and the vehicle group was administered with the same amount of vehicle, the administration was carried out once per day and lasted for two weeks. During the whole experiment, the body weight and the tumor sizes of the mice were measured twice each week, and whether or not the presence of toxic reactions was observed.
Tumor Volume (TV) was calculated by: TV=0.5*a*b2, where a was  the long diameter of the tumor and b was the short diameter of the tumor.
The curves for the tumor volume change of four experimental groups were shown in Figure 1, and the curves for the body weight change of four experimental groups were shown in Figure 2.
In summary, furmonertinib mesilate 15 mg/kg produced moderate anti-tumor activity; furmonertinib mesilate 30 mg/kg and furmonertinib mesilate 50 mg/kg produced extremely significant anti-tumor activity, and the three furmonertinib mesilate groups had little effect on the body weight of mice, and showed good safety.
