- the block was taken by conventional small inoculation method, 1 piece/mouse (about 6mm 3 ). After 6-7 days, the tumor was grown and touched in time (about 20mm 3 ). The animals were randomly divided into 4 groups, each group 6-9 Only, weigh the weight and label.
- the 4 groups were the control group, the positive drug (erlotinib hydrochloride, 200 mg/kg, synthesized in this laboratory), the control group, the high- and low-dose group of Ektinib hydrochloride I (200, 50 mg/kg).
- the experimental group was intragastrically administered once a day. The number of doses depends on the tumor growth.
- the rats were housed at room temperature 20-22 ° C, relative humidity 40-60%, and shielded system with clean layer flow rejection.
- Tumor inhibition rate [1 - mean tumor weight (T) of the administration group / mean tumor weight of the control group (C)] 100%
- the inventors of the present invention also conducted pharmacological toxicology experiments on Beagle dogs, mice, and rats using Ektinib hydrochloride Form I, which showed that: Ektinib hydrochloride has low oral toxicity and no common anti-tumor chemotherapy drugs. Myelosuppressive toxicity, its liver toxicity is reversible during recovery. Safety pharmacological test results showed that ectinib hydrochloride had no effect on respiration, blood pressure and circulatory function, autonomic activity and central nervous system. No results were found in the special toxicity test for teratogenicity, mutagenicity and reproductive toxicity.
- the inventors of the present invention also conducted non-clinical pharmacokinetic studies on Becgle dogs and rats using Ekentine hydrochloride Form I, which showed that: Ecetinib hydrochloride is well absorbed by oral administration, and the absolute bioavailability is Different animal strains reach 27%-62%.
- the drug has a short peak time in the body, mainly excreted in the feces, and a small part is excreted in the urine.
- Ecetinib hydrochloride is widely distributed in various tissues and low in brain tissue, indicating that the drug does not easily pass the blood-brain barrier. There was no significant induction of rat liver P450 enzyme, and no inhibition of drug-metabolizing enzyme by ectinib hydrochloride was found.
- Tablets prepared by using ectinib hydrochloride Form I have completed 10 dose groups of 25 mg, 50 mg, 100 mg, 150 mg, 225 mg, 325 mg, 425 mg, 575 mg and 1025 mg in clinical phase I clinical subjects.
- a safety study of a single administration showed that a dose of 25 mg to 1025 mg was safe.
- Non-small lung cancer (NSCLC) has completed clinical trials in 104 cases.
- the administration method employed is a tablet prepared by oral administration of ectatinib hydrochloride Form I on a fasting basis.
- the results of the evaluation of body efficacy are shown in Table 1. The following terms are precisely explained as: PR: partial relief, CR: complete remission, SD: stable disease, PD: disease progression, ORR: objective response rate, DCR: disease control rate.
- PR partial relief
- CR complete remission
- SD stable disease
- PD disease progression
- ORR objective response rate
- DCR disease control rate.
- Test 7 Rat pharmacokinetic test of different crystalline forms of ectinib hydrochloride and free base
- Ektorinib free base
- Sodium carboxymethylcellulose a pharmaceutical excipient.
- Wistar rats half male and half female, each weighing 150-220 g.
- Rat test Suspension is administered intragastrically. Each group of Wistar rats was fasted for 12 hours before administration and was given free access to water. Administered with a dose equivalent to 35 mg 'kg - 1 of ectinib hydrochloride (administered in a volume of 10 ml.kg- 1 ), 1.0 min, 2.0 min before and 30 min after dosing , 3.0 minutes, 6.0 minutes, 10.0 minutes, 24.0 minutes, in the posterior venous plexus (or tail vein), take 0.5- 1. Oml, place in heparinized tubes, centrifuge, and draw the upper plasma, - 20 ° C to be tested .
- the sample was analyzed by high performance liquid chromatography.
- the chromatographic conditions were: octadecylsilane bonded silica as the stationary phase; 0.02 mol/L sodium dihydrogen phosphate solution - acetonitrile (40: 60, with sodium hydroxide)
- the test solution was adjusted to a pH of 5.0) as a mobile phase with a detection wavelength of 334 nm.
- the area under the curve when the drug is obtained is as follows: Area under the curve of the drug (0-t) Area under the curve of the drug (0-infinity) Crystal form I 91.80 93.73
