Description
Cross Reference to Related Applications
This application claims priority to chinese patent application No. 201911086889.9 filed on 8/11/2019 and chinese patent application No. 202010321669.6 filed on 22/4/2020, both of which are hereby incorporated by reference in their entirety.
The invention belongs to the field of medicine. More specifically, the invention relates to an FGFR inhibitor or a pharmaceutically acceptable salt thereof for treating FGFR-related tumors, a pharmaceutical composition comprising the same, a method for treating FGFR-related tumors by using a medicament containing the same and application thereof in preparing a medicament for treating FGFR-related tumors.
Fibroblast Growth Factor Receptors (FGFR) are receptors for Fibroblast Growth Factor (FGF) signaling, and a family thereof is composed of four members (FGFR 1-4). FGF plays an important role in many physiological regulatory processes, such as cell proliferation, cell differentiation, cell migration, and angiogenesis, through FGFR. Many studies show that FGF signaling pathway abnormalities (high expression, gene amplification, gene mutation, chromosome recombination, etc.) are directly associated with many pathological processes such as tumor cell proliferation, migration, invasion, and angiogenesis, and FGFR shows overexpression or overactivation in various tumors such as non-small cell lung cancer, breast cancer, gastric cancer, bladder cancer, urothelial cancer, endometrial cancer, liver cancer, prostate cancer, cervical cancer, colon cancer, esophageal cancer, myeloma, and the like. For example, FGFR2 fusion mutations were found to occur in about 10-20% of intrahepatic cholangiocarcinoma patients; the change of the FGFR3 gene has stronger correlation with low-grade pathological and low-grade clinical cancers in bladder cancer, and more than 70 percent of low-grade pathological non-invasive urothelial papillomas contain FGFR3 mutation; and the high expression of FGFR1, FGFR2 and FGFR3 is found in gastric cancer tissues and gastric cancer cells. Therefore, FGFR becomes an important therapeutic target and attracts extensive research and development interest.
Depending on the mechanism of action, inhibitors targeting the kinase domain within the FGFR membrane can be classified into ATP competitive inhibitors, non-ATP competitive reversible inhibitors and irreversible inhibitors, wherein the inhibitory activity of the non-ATP competitive reversible inhibitors and irreversible inhibitors on kinases is not affected by high ATP concentrations in cells and in vivo. In recent years, some FGFR-targeted drugs for treating the above tumor diseases have entered clinical trials, and Balversa (Erdafitinib) becomes the first worldwide FGFR reversible inhibitor targeting drug approved by FDA for metastatic urothelial cancer. In addition, other FGFR1-4 inhibitors (e.g., BGJ-398, Debio-1347, TAS-120, etc.) are in different clinical stage trials for solid tumors such as urothelial cell carcinoma and liver cancer. The structural formula of the medicine is as follows:
however, researches show that the reversible inhibitor of pan FGFR (pan-FGFR), such as BGJ-398, is difficult to avoid generating drug resistance after being used for 4-6 months, so that the curative effect is reduced, and the irreversible inhibitor, such as TAS-120, is still effective for patients after being resistant to BGJ-398, thereby showing the unique advantages of the irreversible inhibitor. However, no FGFR1-4 irreversible inhibitor has been approved for marketing at home and abroad so far.
Primary liver cancer (liver cancer for short) is a common malignant tumor, is the cause of cancer death of the 4 th cause worldwide, and poses serious threat to human life health. Liver cancer mainly includes hepatocellular carcinoma (HCC), Intrahepatic Cholangiocellular Carcinoma (ICC), and mixed hepatocellular carcinoma (c-CC). Liver cancer has no obvious clinical symptoms in early stage, is found to be in middle and late stages frequently, and has the advantages of high malignancy degree, high recurrence rate, poor treatment effect and poor prognosis. The clinical treatment means for liver cancer mainly include surgical treatment, Transcatheter Arterial Chemoembolization (TACE), radiotherapy and chemotherapy. However, the residual liver tissue of post-operative patients still presents a risk of cancer, with a 5-year risk of recurrence of more than 70%. Sorafenib (Sorafenib) is the only currently approved molecular targeted drug for treating advanced liver cancer, but it is still poorly effective in liver cancer patients with liver function Child-Pugh graded as grade B.
Urothelial cancer (UCC) is a common malignant tumor worldwide and is one of the most common clinical malignant tumors in urology surgery in China, and 90-95% of urothelial cancer is bladder cancer. The initial diagnosis of urothelial cell carcinoma is mostly non-muscle layer infiltrative, but the urothelial cell carcinoma has high recurrence rate; and with the increase of the number of relapses, the malignancy of the tumor is improved and transformed into a muscle-layer-infiltrating tumor. Patients with metastatic urothelial cancer with FGFR gene changes have poor prognosis and low response rate to treatment, and the patients have far-unmet significant clinical requirements. For decades, the standard of treatment for urothelial cancer has been Cisplatin (cissplatin) -based chemotherapy regimens. The second-line chemotherapeutic drugs Vinflunine (Vinflunine) or taxanes (taxanes) have slightly improved efficacy, with historical Objective Remission Rates (ORR) of only about 10% and an overall median survival (OS) of 7-9 months. Advanced or metastatic urothelial cancer also has an overall response rate of only 15% to 20% to the recently approved PD-1/PD-L1 checkpoint inhibitor, with a median OS of about 10 months, and thus many patients do not benefit.
Gastric cancer (gastric cancer) is also one of the common malignant tumors in the world, has relatively poor prognosis and seriously threatens human health. Due to the lack of a mature early screening system, atypical and low-rate detection of early gastric cancer symptoms, most patients are diagnosed with advanced stages. The current therapeutic measures for gastric cancer mainly include surgical treatment, systemic application of chemical drugs, radiotherapy and molecular targeted drug therapy. The targeted therapy is the drug therapy aiming at the specific target of the tumor, but because of strong heterogeneity of the gastric cancer and the like, the clinical research on the targeted therapy of the gastric cancer is less successful and has more failures.
Cholangiocarcinoma (CCA) is an epithelial malignancy with distinct cholangiocellular differentiation characteristics, with an increased incidence of nearly 20% over the past 10 years, accounting for approximately 3% of digestive tract tumors and 10-15% of hepatobiliary malignancies. Biliary tract cancers can be classified, depending on the anatomical location, as intrahepatic and extrahepatic cholangiocarcinoma (eCCA), which is further classified as supraportal cholangiocarcinoma (pCCA) and distal cholangiocarcinoma (dCCA). Radical surgery is the only cure, but there is no characteristic clinical manifestation in the early stage of the disease, about 2/3 patients lose the chance of surgery at the time of initial diagnosis, and 5-year survival rate is about 10%. Even after surgical resection, the 1-year recurrence rate of cholangiocarcinoma is still as high as 50%. For unresectable local progression stage metastatic biliary tumors (including intrahepatic and extrahepatic bile duct cancer, gallbladder cancer (ampulla ampullate), etc.), the standard first-line chemotherapy regimen (gemcitabine in combination with cisplatin) only resulted in median survival of 11.7 months with very poor prognosis. However, the FGFR inhibitor has shown a prospect in the clinical test of the bile duct cancer, for example, the FGFR inhibitor BGJ-398 obtains excellent phase II test results in advanced bile duct cancer with FGFR gene fusion, mutation and amplification, and the objective remission rate and the disease control rate reach 18.8% and 83.3% in FGFR gene fusion patients.
Intrahepatic cholangiocarcinoma refers to malignant tumor of biliary duct epithelium at two or more levels in liver, also called intrahepatic cholangiocarcinoma, belongs to one of primary liver cancer (accounting for 10% -15%), and can also belong to one of bile duct cancer (accounting for about 10%) according to the occurrence part. The intrahepatic bile duct cancer has high malignancy degree, extremely strong invasion and lymph node metastasis characteristics, difficult early diagnosis and poor patient prognosis, the overall survival rate of 5 years is lower than 10 percent, and the median survival time after surgical resection is 36 months. The only current method for curing intrahepatic bile duct cancer is early detection and surgical resection, but the recurrence rate after resection is high. Patients with locally advanced unresectable and recurrent metastases are even deficient in effective measures that significantly improve prognosis. Intrahepatic bile duct cancer is insensitive to traditional chemotherapy, radiotherapy and recent tumor immunotherapy, and no standard treatment method is available for bile duct cancer patients who fail to receive first-line gemcitabine chemotherapy. The literature reports that patients receiving second-line chemotherapy with various regimens of 5-fluorouracil (5-FU) and irinotecan, 5-FU and oxaliplatin, 5-FU and cisplatin, 5-FU or capecitabine and sunitinib have median progression-free survival (PFS) and Overall Survival (OS) of 3.2 and 6.7 months, respectively, with no significant difference in PFS or OS between the regimens. The molecular mechanism research of intrahepatic bile duct cancer has been reported more. A comprehensive genome analysis of 260 cholangiocarcinoma patients by Nakamura et al revealed that 40% of cases exhibited an alteration in the FGFR gene, with FGFR2 exhibiting high expression in intrahepatic cholangiocarcinoma. It is also found by using a second-generation sequencing technology that 13% -50% of patients with intrahepatic bile duct cancer carry FGFR2 gene fusion, wherein 13.6% of patients containing FGFR2-BICC1 and FGFR2-AHCYL1 gene fusion. These findings provide new opportunities for the treatment of intrahepatic bile duct cancer.
Currently, several FGFR inhibitors are currently in different stages of clinical study on bile duct cancer, such as BGJ-398 (reversible selective inhibitor), ARQ087(ATP competitive inhibitor), TAS-120 (irreversible pan FGFR inhibitor), etc., and the FGFR inhibitor used in bile duct cancer was first reported to be BGJ-398. Studies report that 3 patients with FGFR2 fusion positive intrahepatic bile duct cancer treated with BGJ-398 develop clinically acquired FGFR inhibitor resistance, and further studies found polyclonal secondary mutations in the kinase domain of FGFR2, which included the FGFR2V564F gene mutation in all of the 3 patients. TAS-120 is a highly selective irreversible pan FGFR inhibitor. The research shows that the TAS-120 has clinical curative effect on BGJ-398 resistant intrahepatic bile duct cancer patients, and can inhibit secondary mutation of various FGFR 2. However, no document discloses data on the cellular level inhibitory activity of TAS-120. At present, no targeted medicine for treating intrahepatic bile duct cancer is approved to be on the market.
WO2019034076a1 discloses FGFR inhibitors and their medical use, including compound a (example 2). The patent application discloses the evaluation result of the in vitro inhibitory activity of the compound A on FGFR wild type kinase, the evaluation result of the in vitro inhibitory activity of mutant type kinase and the evaluation result of pharmacokinetics in mice, but does not disclose that the compound A can be specifically used for treating diseases.

The above embodiments represent exemplary embodiments of the present invention, but the present invention is not limited to the above embodiments. In addition, the various features of the above embodiments of the invention may be combined with each other to form one or more new solutions, which also fall within the scope of the invention, as long as such new solutions are technically feasible.
[ advantageous effects of the invention ]
In order to prove that the compound A is an FGFR1-4 inhibitor which is effective on FGFR-related tumors, particularly digestive or urinary system tumors, the invention evaluates the in vitro kinase inhibition activity of the compound A on FGFR1-4 wild type and mutant type and the proliferation inhibition activity of exemplary digestive or urinary system tumors (including gastric cancer, liver cancer, bladder cancer and bile duct cancer) models related to FGFR, and further evaluates the inhibition effect of the compound A on the tumor growth aiming at a plurality of tumor xenograft models.
In vitro kinase activity test and cell test results show that the compound A has good in vitro kinase inhibition activity on both wild type and mutant type of FGFR 1-4; the compound has good inhibition effect on the proliferation of human gastric cancer cells (SNU-16) with FGFR2 gene amplification, human bladder cancer cells (RT112/84) with FGFR3 high expression and FGFR3-TACC3 fusion, human liver cancer cells (Hep3B) with FGFR4/FGF19 high expression, human bile duct cancer cells HuCCT1 with FGFR2 high expression and human intrahepatic bile duct cancer cells RBE; has obvious inhibiting effect on a human stomach cancer SNU-16 cell subcutaneous xenograft tumor model, a human bladder cancer RT112/84 cell subcutaneous xenograft tumor model and a human liver cancer LI-03-0332 subcutaneous xenograft model.
In addition, in order to examine the drug-forming properties of compound a, the present inventors measured the plasma stability of compound a in human and mouse plasma stability tests and compared it with a reference compound of close structure (example 8(S configuration) in WO2019034076a 1). Plasma stability results show that compound a has better stability in both mouse and human plasma.
Furthermore, it is known that irreversible inhibitors enhance affinity to a target through covalent bonding to a target protein, relative to reversible inhibitors, which is a fundamental reason why irreversible inhibitors exhibit high biological activity. However, if off-target, this affinity enhancement of irreversible inhibitors would also occur at off-target sites, and thus would also lead to enhanced toxic side effects [ see populus et al, small molecule covalent inhibitor research advances, pharmaceutics, 2014, 49 (2): 158-165]. Due to the worry that irreversible inhibitors can bring larger toxic and side effects, the invention detects the off-target effect of the compound A on a plurality of important non-target kinases, and the result shows that the off-target effect of the compound A is lower.
Still further, in order to evaluate the safety of compound a in vivo, the present invention conducted a safe pharmacological test and an acute toxicity test for dogs and mice. The result shows that the compound A has no obvious influence on each detection index and has good safety.
In conclusion, the inventor of the application finds that the compound A has the activity of selectively inhibiting FGFR1-4, has good inhibitory activity on both wild type FGFR1-4 and mutant FGFR1-4, can obviously inhibit the proliferation of digestive or urinary system tumor cells and a xenograft tumor model related to the abnormal expression of FGFR1-4, and has higher plasma stability and safety. Therefore, the compound A has the activity of inhibiting digestive or urinary system tumors related to the abnormal expression of FGFR, can be used for developing medicaments for treating digestive or urinary system tumor diseases, and has important clinical application value.

Electrocardiograms, heart rate and blood pressure were recorded continuously for all experimental animals from at least 2 hours before each administration to about 24 hours after administration. Electrocardiographic waveforms of about 30 seconds length were printed at 2 time points before dosing (at least 30 minutes apart) and 6 time points after dosing (0.5 hour, 1 hour, 2 hours, 4 hours, 12 hours, and 24 hours after dosing) for each dose. The results show that, under the test conditions, no change in cardiovascular index associated with the test article was observed in beagle dogs upon single oral gavage of test compound a at doses of 0.3, 0.6 and 2mg/kg within 24 hours after administration.
The SD rats were given test compound a by single oral gavage and their effect on respiratory function was evaluated. Each 20 rats in males and females are divided into 4 groups of 5 rats in each group, and a control formulation (vehicle: containing 0.5% (w/v) methylcellulose and 0.2% (w/v) aqueous Tween 80) or 0.5, 1.2 or 3mg/kg of test Compound A is administered orally. All animals were dosed in a volume of 5 mL/kg. Prior to dosing, respiratory data (tidal volume, respiratory rate, minute ventilation) was collected for approximately 15 minutes as a pre-group respiratory parameter baseline. The time points collected on the day of administration were data collected for approximately 15 consecutive minutes each before administration, 2 hours after administration, 8 hours after administration, and 24 hours after administration. The results show that 24 hours after a single oral administration, no effect of the test article on rat respiratory rate, tidal volume and minute ventilation was observed.
The results of the experiment are shown in Table 14.
Table 14: safety pharmacological test results
And (4) conclusion: the compound A has no influence on the central nervous system and respiratory system of SD rats and the cardiovascular system of beagle dogs, and the compound A is high in safety.
Example 11: acute toxicity test
1. Single-time gavage toxicity test in rats
The test method comprises the following steps: 40 rats were randomly divided into 4 groups of 10 rats each, each half of males and females, and administered compound A and a control solvent, respectively, in a single oral gavage, at a dose of 10, 40 or 400mg/kg, respectively, in an aqueous solution containing 0.5% (w/v) MC and 0.2% (w/v) Tween 80, to test the maximum tolerated dose of compound A. The administration volume was 10mL/kg and the observation period was 14 days.
And (3) test results: a slight increase in yellow abnormal stool and total bilirubin was observed only in the 400mg/kg dose group. No significant difference in test article-related death, clinical symptoms, macroscopic lesions, weight change, food intake and clinical tests (hematology, hemagglutination, serum biochemistry and urinalysis) is found in the male and female animals of other dose groups compared with the solvent control group. Thus, the Maximum Tolerated Dose (MTD) for a single administration under the conditions of this test was 400 mg/kg.
2. Single gavage toxicity test for dogs
The test method comprises the following steps: 8 beagle dogs, randomly divided into 4 groups of 2 dogs each, hermaphrodite halves, were given a single oral gavage of compound A at 15, 50 or 250mg/kg, respectively, and a control solvent in the form of an aqueous solution containing 0.5% (w/v) MC and 0.2% (w/v) Tween 80. The administration volume was 5 mL/kg. Animals were fasted overnight prior to dosing. The observation period was 14 days. The males and females were necropsied on day 21.
And (3) test results: a single gavage of 15, 50 or 250mg/kg compound a in beagle dogs did not produce test-related mortality, clinical symptoms, body weight, food intake, hematology, blood clotting, serum biochemistry, urinalysis parameters, macroscopic lesions, and histopathological adverse reactions. Therefore, the Maximum Tolerated Dose (MTD) of the male and female beagle dogs under the test conditions was considered to be 250 mg/kg.
And (4) conclusion: the compound A has higher tolerance dose in single-time gastric lavage administration toxicity test and good safety.
