    L.01.X.E.05   Sorafenib

    Pharmacodynamics:FROMorafenib is a multi-kinase inhibitor. Reduces the proliferation of tumor cells in vitro.

    Shown, that sorafenib suppresses numerous intracellular kinases (c-CRAF, BRAF and mutant BRAF) and kinases located on the cell surface (KIT, FLT- 3, RET, VEGFR-1, VEGFR-2, VEGFR-3 and PDGFR- AT). It is believed that some of these kinases are involved in the signaling systems of the tumor cell, in the processes of angiogenesis and apoptosis. Sorafenib Suppress tumor growth in hepatocellular carcinoma, renal cell carcinoma, The metabolism of sorafenib is carried out, differentiated thyroid cancer in humans.

    Pharmacokinetics:

    After taking sorafenib tablets, its average relative bioavailability is 38-49%. The half-life of sorafenib is approximately 25-48 hours. The administration of repeated doses of sorafenib for 7 days resulted in a 2.5-7-fold increase in accumulation compared with single dose administration.

    The equilibrium concentrations of sorafenib in plasma are reached within 7 days, the ratio of the maximum / minimum concentration of less than 2. The pharmacokinetics of sorafenib in an equilibrium state at a dose of 400 mg 2 times daily ingestion studied in patients with thyroid cancer, hepatocellular carcinoma and renal cell carcinoma. The highest exposure was noted in patients with thyroid cancer, although the exposure variability was high for all types of tumors. The clinical significance of a larger area under the concentration-time curve (AUC) in patients with thyroid cancer is not established.

    Suction and distribution

    The maximum concentrations (Сmа) of sorafenib in plasma are reached approximately in 3 hours after intake.When taken with food with a moderate fat content The bioavailability of sorafenib approximately corresponds to bioavailability when administered on an empty stomach. When taken with a high-fat diet, bioavailability is reduced by approximately 29% compared with fasting.

    When administering oral doses exceeding 400 mg twice a day, the average Cmax and the area under the curve "concentration-time" (AUC) increase disproportionately. The connection with proteins is 99.5%.

    Metabolism and excretion

    Sorafenib metabolism is mainly carried out in the liver by oxidation mediated by isoenzyme CYP3A4, as well as by glucuronation, mediated UGT1A9.

    Sorafenib conjugates can be cleaved in the gastrointestinal tract due to the activity of bacterial glucuronidase, which allows reabsorption of unconjugated drug means. Simultaneous use of neomycin affects this process, reducing the average bioavailability of sorafenib up to 54%.

    When an equilibrium state is reached on sorafenib accounts for approximately 70-85%. 8 metabolites were identified without hepatocellular carcinoma with the lungs (class A according to the Child-Pugh classification) or with medium-heavy (class B according to the Child-Pugh classification) has a disability in vitro activity similar to that of sorafenib, and is approximately 9-16%.

    After oral administration of a dose of 100 mg of sorafenib in the form of a solution within 14 days, 96% of the prescribed dose is withdrawn, 77% is excreted through the intestines, 19 % - kidneys in the form of glucuronides. Unchanged sorafenib, in the amount of 51% of the prescribed dose, is determined in the stool.

    Pharmacokinetics in special populations

    An analysis of demographic data suggests that dose adjustment of the drug, depending on age or sex, is not required.

    Children

    Data on the pharmacokinetics of the drug in children are absent.

    Renal insufficiency

    The pharmacokinetics of sorafenib were studied after a single dose of 400 mg in patients with normal renal function and in patients who did not need dialysis with a mild (creatinine clearance 50-80 ml / min), moderate (QC 30 to <50 ml / min ) and severe (QC <30 ml / min) decrease in renal function. The effect of decreased renal function on the pharmacokinetics of sorafenib was not detected. For patients with mild, moderate or severe degree of renal failure, not requiring hemodialysis, there is no need to reduce the dosage.

    Liver failure

    Sorafenib is excreted mainly by the liver. In patients with hepatocellular carcinoma with a lung (Class A Child-Pugh classification) or moderate (class B Child-Pugh classification) degree of hepatic insufficiency, the pharmacokinetic parameters of sorafenib were the same as in patients with normal hepatic function. The pharmacokinetics of sorafenib in patients without hepatic cell carcinoma with a lung (class A Child-Pugh classification) or moderate (class B Child-Pugh classification) degree of hepatic insufficiency was similar to the pharmacokinetics of sorafenib in healthy individuals. In patients with severe hepatic insufficiency (class C according to the Child-Pugh classification), the pharmacokinetics of sorafenib have not been studied.

    Indications:

    Metastatic renal cell carcinoma.

    Hepatic-cell carcinoma.

    Locally distributed or metastatic differentiated thyroid cancer, resistant to radioactive iodine.

    Contraindications:

    Hypersensitivity to sorafenib or to any other component of the drug.

    Pregnancy and lactation.

    Children's age (efficacy and safety of use not established).

    Carefully:
    With skin diseases, with arterial hypertension, with increased bleeding or bleeding history, with unstable angina pectoris, myocardial infarction, with therapy with irinotecan.
    Pregnancy and lactation:

    Pregnancy

    Women should avoid pregnancy during the treatment with Nexavar. Women with preserved reproductive capacity should be informed of the potential risk of Nexavar for the fetus, which includes teratogenicity, problems with fetal survival and embryotoxicity. During and for at least 2 weeks after therapy with Nexavar, reliable methods of contraception should be used.

    Studies of the drug Nexavar in pregnant women were not conducted. In animal studies, the reproductive toxicity of sorafenib is shown, including the ability of this substance to cause malformations. In experiments on rats, it was shown that sorafenib and its metabolites penetrate the placenta. It is assumed that sorafenib inhibits angiogenesis in the fetus.

    Breastfeeding period It is not known whether sorafenib with human milk. In animals, there is a separation with milk of sorafenib and / or its metabolites. Since many medicines are excreted in breast milk and the effect of sorafenib on young children has not been studied, women should stop breastfeeding during the Nexavar treatment period.

    Dosing and Administration:

    The recommended daily dose Nexavar is 800 mg (4 tablets of 200 mg each). The daily dose is given in two divided doses (2 tablets twice a day) or in between meals, or along with food containing a low or moderate amount of fat. The tablets are swallowed with a glass of water. Treatment continues as long as the clinical efficacy of the drug persists or until its unacceptable toxic effects occur. The development of possible unwanted drug reactions may require a temporary discontinuation and / or a reduction in the dose preparation Nexavar.

    Dose reduction in patients with metastatic renal cell carcinoma and hepatocellular carcinoma

    If necessary, the dose Nexavar can be reduced to 400 mg once a day or up to 400 mg every other day.

    Individual groups of patients

    Children

    Safety and effectiveness of the appointment Nexavar in children is not established. Correction of dose, depending on the age of the patient (over 65 years of age), sex or body weight is not required.

    Decreased liver function

    Patients with impaired hepatic function classes A and B according to the Child-I do not need a dose adjustment. Treatment with Nexavar patients with a decrease in the liver function of class C according to the Child-Pugh classification has not been studied.

    Decrease kidney function

    Patients with light, medium-heavy and severe degree of renal failure (without hemodialysis) no dose reduction is required preparation Nexavar. Using Nexavar in the treatment of patients on hemodialysis, has not been studied.

    Patients with a risk of renal dysfunction should monitor the water-electrolyte balance.

    In clinical studies in patients palmar-plantar erythrodysesthesia, diarrhea, alopecia, weight loss, fever, hypocalcaemia, keratoacanthoma / squamous cell carcinoma of the skin were significantly more frequent than in patients with renal cell carcinoma and hepatocellular carcinoma.

    Overdose:In case of an overdose, it is possible to intensify the above undesirable phenomena, especially diarrhea and skin reactions.
    Treatment is symptomatic. The antidote to sorafenib is unknown.
    Interaction:

    Inductors CYP3A4: drugs that induce activity CYP3A4 (eg, rifampicin, phenytoin, carbamazepine, phenobarbital, dexamethasone and preparations containing St. John's wort extract) can increase the metabolism of sorafenib and, thus, reduce its concentration in the body.

    Continuous simultaneous administration of sorafenib together with rifampicin resulted in a decrease AUC (area under the concentration-time curve) of sorafenib in an average of 37%.

    Inhibitors of CYP3A4: clinical pharmacokinetic interactions sorafenib with cytochrome inhibitors CYP3A4 unlikely.

    Substrates CYP2C9: simultaneous administration of sorafenib and warfarin did not lead to a change in mean values prothrombin time and international normalized relationship (INR) compared with placebo. However, a regular determination of MNO is recommended for all patients receiving concomitant therapy with warfarin and sorafenib.

    Substrates of specific isoenzymes from the cytochrome P450 group: simultaneous administration of midazolam, dextromethorphan and omeprazole, which are substrates of cytochromes CYP3A4, CYP2D6 and CYP2C19 respectively, and a 4-week course of sorafenib did not lead to a change in the level of exposure of these drugs. These observations indicate that sorafenib neither inhibits nor induces isoenzymes from the cytochrome P450 group. As a result of the simultaneous use of sorafenib and paclitaxel, there was an increase and not a decrease in the exposure of 6-OH-paclitaxel, the active metabolite of paclitaxel, which is formed by CYP2C8. These data indicate that sorafenib in vivo may not be an inhibitor CYP2C8. Simultaneous use of sorafenib and cyclophosphamide resulted in a slight decrease in the exposure of cyclophosphamide,However, there was no decrease in systemic exposure of 4-OH-cyclophosphamide, which is an active metabolite of cyclophosphamide, which is formed mainly by CYP2B6. These data indicate that sorafenib in vivo may not be an inhibitor CYP2B6.

    Combination with other antitumor drugs:

    sorafenib does not have a clinically significant effect on the pharmacokinetics gemcitabine, cisplatin, carboplatin, oxaliplatin and cyclophosphamide.

    Paclitaxel / carboplatin

    The simultaneous use of paclitaxel (225 mg / m2) and carboplatin (AUC = 6) together with sorafenib (<400 mg twice daily), with 3-day intervals in the administration of sorafenib before and after administration of paclitaxel and carboplatin, had no significant effect on the pharmacokinetics of paclitaxel. The simultaneous use of paclitaxel (225 mg / m2 every 3 weeks) and carboplatin (AUC = 6) with sorafenib (400 mg twice a day without interruption in the use of sorafenib) resulted in an increase in sorafenib exposure by 47%, paclitaxel by 29 % and 6-OH of the paclitaxel derivative by 50%. The pharmacokinetics of carboplatin remained unchanged.

    These data show that there is no need to adjust the dosage when applying paclitaxel and carboplatin together with sorafenib with 3-day intervals in the administration of sorafenib. The clinical significance of an increase in the exposure of sorafenib and paclitaxel is not known with simultaneous application with sorafenib without interruption in its use.

    Capecitabine

    Simultaneous use of capecitabine (750-1050 mg / m2 2 times a day from the 1st to the 14th day every 21st day) and sorafenib (200 or 400 mg twice a day without interruptions in admission) did not lead to significant changes in the exposure of sorafenib, but exposure capecitabine increased by 15-50%, and exposure to fluorouracil (a metabolite of capecitabine) increased by 0-52%.

    The clinical significance of this small or moderate increase in the exposure of capecitabine and fluorouracil remains unknown with the simultaneous administration of sorafenib.

    Doxorubicin / irinotecan

    The simultaneous administration of sorafenib and doxorubicin results in an increase AUC doxorubicin by 21%. With the simultaneous administration of sorafenib and irinotecan, the active metabolite of which SN-38 further metabolized with participation UGT1A1, there was an increase AUC SN-38 by 67-120% and the increase AUC irinotecan by 26-42%. It remains unknown clinical significance of observational data.

    Docetaxel

    Simultaneous use of docetaxel (75 or 100 mg / m2 once every 21 days) and sorafenib (200 or 400 mg twice daily from day 2 to day 19 during the 21-day cycle) with 3-day intervals before and after docetaxel administration is accompanied by an increase AUC and C max docetaxel, respectively, at 36-80 % and 16-32%. At simultaneous appointment of sorafenib and docetaxel Care should be taken.

    Neomycin

    Simultaneous use of neomycin, non-systemic antibacterial drug for eradication of the gastrointestinal The influence of the flora enterohepatic circulation sorafenib followed by a decrease exposure of sorafenib. In healthy volunteers who received neomycin at for 5 days, the average bioavailability sorafenib decreased to 54%. The clinical significance of these data is not is known. Influence of other antibiotics on the pharmacokinetics of sorafenib have not been studied, It is assumed that this influence will be be determined by the ability of antibiotics reduce the activity of glucuronidase.

    Combination with proton pump inhibitors

    Omeprazole

    The simultaneous use of omeprazole is not has an effect on the pharmacokinetics sorafenib. Dose adjustment Sorafenib is not required.

    Special instructions:

    Treatment with Nexavar should be conducted under the supervision of a specialist with experience in the use of antitumor drugs.

    During therapy with Nexavar it is necessary to periodically monitor the parameters of peripheral blood (including the leukocyte formula and platelets). The most frequent adverse reactions during admission Nexavar there were skin reactions in the limbs (palmar-plantar erythrodysesthesia) and rash. In most cases, they were 1 th and 2 nd severity and manifested mainly during the first six weeks of treatment with Nexavar. To treat skin toxic reactions, local drugs with symptomatic effect can be used. If necessary, temporarily stop treatment and / or change the dose Nexavar or, in severe or repeated cases of skin reactions, therapy with Nexavar cancel.

    In patients who received treatment drug Nexavar, an increase in the incidence of hypertension was documented. Arterial gIpertension was usually mild or moderate, was observed at the beginning of treatment and was treatable with standard antihypertensive preparations. During treatment drug Nexavar should be monitored regularly arterial pressure and, if necessary, adjust its increase in antihypertensive therapy.

    In cases of severe or persistent development arterial hypertension or with the appearance of hypertensive crises, despite the conduct of adequate antihypertensive therapy, consideration should be given to discontinuing Nexavar treatment.

    The drug Nexavar can lead to increased risk of bleeding. Severe bleeding occurs rarely. When any bleeding that requires medical intervention occurs, it is recommended to consider discontinuation of treatment with Nexavar.

    Given the potential risk bleeding, in patients with differentiated thyroid cancer before prescribing Nexavar, local treatment of tumor tracheal infiltrates should be performed,bronchi and esophagus.

    With co-administration of warfarin and Nexavar in some patients rare episodes of bleeding or increased Normalized Relationship (INR). With co-administration of warfarin and Nexavar a regular determination of prothrombin time, INR, clinical signs bleeding.

    In the case of surgical interventions, temporary discontinuation of therapy is recommended with Nexavar from the standpoint of precaution. Clinical observations regarding resumption of admission Nexavar after surgical interventions, very few. Therefore, the decision to resume therapy with the drug

    Nexavar after surgical interventions should be based on a clinical assessment of the adequacy of wound healing.

    If you experience ischemia and / or myocardial infarction, you should temporarily or permanently discontinue therapy with Nexavar. It has been established that the use of Nexavar leads to lengthening of the interval QT / QTc, which may increase the risk of developing ventricular arrhythmias. It should be applied Nexavar with caution in the following patients with a current lengthening interval QTc or with the risk of developing this condition: with a congenital syndrome of an elongated interval QT; receiving anthracycline therapy at a high total dose; taking certain antiarrhythmic drugs or other drugs leading to lengthening of the interval QT; as well as in patients with electrolyte disorders, including hypokalemia, hypocalcemia, or hypomagnesemia. When Nexavar is used in such patients, periodic electrocardiographic monitoring should be performed and the concentration of electrolytes (magnesium, potassium, calcium) should be measured.

    Perforation of the gastrointestinal tract is infrequent and described in less than 1% of patients who received Nexavar. In some cases, these events were not associated with tumors in the abdominal cavity. In case of perforation of the gastrointestinal tract, treatment with Nexavar should be discontinued. There are no data on the treatment with Nexavar with patients with severe hepatic impairment (Child-Pugh class C). Because the sorafenib is excreted mainly by the liver, in patients with severe impairment of liver function, the effect of the drug may be increased.

    When using Nexavar in patients with differentiated thyroid cancer, it is recommended to monitor the concentration of calcium in the blood. In clinical studies in patients with differentiated thyroid cancer, especially those with a history of hypoparathyroidism, there have been more frequent and severe manifestations of hypocalcemia than in patients with renal cell and hepatocellular carcinoma.

    In some patients with differentiated thyroid cancer treated with Nexavar in clinical studies, the thyroid-stimulating hormone concentration exceeded 0.5 mU / L. When using Nexavar, these patients should monitor the concentration of thyroid-stimulating hormone. With caution appoint Nexavar together with drugs that metabolized / withdrawn predominantly with the participation of UGT1A1 (eg, irinotecan).

    Simultaneous use of docetaxel (75 or 100 mg / m2) and Nexavar (200 or 400 mg twice daily) with 3-day intervals before and after docetaxel administration is accompanied by an increase AUC docetaxel by 36-80%. With simultaneous appointment Nexavar and docetaxel should be used with caution.

    The simultaneous use of neomycin may lead to a decrease in the bioavailability of sorafenib.

    In two randomized, placebo-controlled studies, comparing safety and efficacy of the first line of two-component chemotherapy on platinumcarboplatin / paclitaxel and separately gemcitabine / cisplatin) in combination with sorafenib or without it in patients with advanced non-small cell lung cancer (NSCLC), data on overall survival improvement could not be obtained. The safety data, in general, corresponded to the previously described results. However, in both studies in the group of patients with squamous cell lung cancer who received a two-component platinum-based chemotherapy in combination with sorafenib, there was a higher mortality rate compared to the group of patients receiving only two-component platinum-based chemotherapy (paclitaxel / carboplatin: Risk ratio 1.81, 95% confidence interval 1.19-2.74 gemcitabine / cisplatin: risk ratio 1.22, 95% confidence interval 0.82-1.80). The determining reasons for this phenomenon were not revealed.
