Pharmacological properties
Pharmacodynamics
Nilotinib is a protein tyrosine kinase inhibitor, anticancer drug. The mechanism of its action is due to the ability to suppress the tyrosine kinase activity of the Bcr-Abl oncoprotein of cell lines and leukemia cells primarily positive on the Philadelphia chromosome (Ph +).
The pronounced inhibitory effect on the Bcr-Abl wild-type oncoprotein is explained by the high affinity for the binding sites with adenosine triphosphate (ATP). The drug is also active against imatinib-resistant 32 and 33 mutant forms of Bcr-Abl tyrosine kinase, except for the T315I mutation.
In patients with chronic myeloid leukemia (CML), nilotinib induces apoptosis in cell lines and Ph-positive leukemia cells, and selectively inhibits proliferation.
Tasigna has little or no effect on other known protein kinases (including kinase of proteins of the Src family), with the exception of kinases possessing receptors for platelet growth factors (PDGRF), DDR receptors, as well as Kit and ephrin receptors - they are inhibited at concentrations of nilotinib within the therapeutic doses (for oral administration) recommended for the treatment of CML.
In the chronic phase of Ph + CML, therapy with the drug at a dose of 400 mg 2 times a day with ineffectiveness or intolerance to previous therapy (including imatinib) allows a greater cytogenetic response to be achieved (52% of cases). At the same time, the response is achieved quickly (on average, within 2.8 months) and with continued therapy (for 2 years) persists in 77% of patients. The overall survival rate of patients after 24 months of treatment with nilotinib is 87%.
In the phase of acceleration of Ph + CML, therapy with the drug at a dose of 400 mg 2 times a day with the ineffectiveness of previous therapy (including imatinib) or the development of resistance to it, the hematological response is achieved in 55% of cases. In this case, the response is achieved quickly (within 1 month) and with continued therapy (for 2 years) persists in 49% of patients. A greater cytogenetic response is achieved in 32% of patients and, with continued treatment, persists in 66% of cases.
Pharmacokinetics
After oral administration of Tasigna, about 30% of the drug is absorbed. The maximum concentration (C max) is reached within about 3 hours. In healthy volunteers who took the drug with food, there was an increase in C max and AUC (area under the concentration-time curve) by 112 and 82%, respectively, compared with individuals who received capsules on an empty stomach.
In the case of taking Tasigna 30 minutes and 2 hours after meals, an increase in the bioavailability of nilotinib is observed, respectively, by 29 and 15%. In patients undergoing partial or total gastrectomy, the absorption of the drug (relative bioavailability) decreases by about 22 and 48%, respectively.
The bioavailability of the drug dissolved in applesauce does not change when compared with taking whole capsules.
The concentration ratio of nilotinib in blood and plasma is 0.71. In vitro, about 98% of the dose is bound to plasma proteins.
In the equilibrium state, the systemic exposure of the drug was dose-dependent. However, in the case of taking a daily dose of more than 400 mg, the dose dependence of the increase in exposure is less pronounced.
The daily equilibrium concentration (C ss) in plasma is 35% higher when taking a dose of 400 mg twice a day than when taking a dose of 800 mg once a day. AUC after a dose of 400 mg 2 times a day is approximately 13.4% higher than after a dose of 300 mg 2 times a day. Against the background of therapy lasting 12 months, when using the drug at a dose of 400 mg 2 times a day, compared with a dose of 300 mg 2 times a day, an increase in C min (minimum concentration) and C max was noted, respectively, by 15.7 and 14.8% … With an increase in a single dose from 400 mg to 600 mg (with a two-time dose per day), a significant increase in C ss was not observed.
C ss is reached by the 8th day of taking Tasigna. Plasma exposure of nilotinib in the period between the use of the first dose and the achievement of C ss when taking the drug once a day increases by about 2 times, when taken twice a day - 3.8 times.
In the blood plasma, nilotinib circulates mainly unchanged. In studies in healthy volunteers, the active substance was metabolized mainly by oxidation and hydroxylation with the formation of metabolites with insignificant pharmacological activity.
In healthy volunteers, after taking a single dose of the drug, more than 90% was excreted within 7 days, mainly with feces. At the same time, 69% was excreted unchanged.
The half-life (T ½) after repeated administration of Tasigna is approximately 17 hours.
In case of liver dysfunction, no significant changes in the pharmacokinetic characteristics of nilotinib were observed. Compared with individuals without liver dysfunction, in patients with mild, moderate and severe functional liver dysfunctions with a single dose of the drug, a decrease in the AUC of nilotinib was noted by 35, 35 and 19%, respectively. C max in equilibrium increased by 29, 18 and 22%, respectively.
Individual differences in pharmacokinetic parameters among the general population were moderate to significant.
Indications for use
- newly diagnosed Ph + CML in the chronic phase;
- Ph + CML in the chronic phase and in the acceleration phase in case of intolerance to previous therapy (including imatinib) or resistance to it.
Contraindications
Absolute:
- hereditary galactose intolerance, impaired absorption of glucose / galactose, lactase deficiency;
- age up to 18 years;
- period of pregnancy and lactation;
- concomitant use of powerful inhibitors of the isoenzyme CYP3F4 (drugs and food, including grapefruit juice);
- joint administration of drugs that lengthen the QT interval, especially with concomitant hypokalemia or hypomagnesemia;
- hypersensitivity to drug components.
Relative (Tasigna capsules are used with caution, after assessing the benefits and risks):
- pancreatitis (including a history);
- liver dysfunction;
- the presence of risk factors for prolongation of the QT interval (congenital prolongation of the QT interval, severe or drug-induced uncontrolled heart disease, including clinically significant bradycardia, unstable angina pectoris, chronic heart failure, myocardial infarction).
Tasigna, application instruction: method and dosage
Tasigna should be taken orally, between meals - not earlier than two hours after a meal and not later than one hour before the next meal. The capsules are swallowed whole with plenty of water. Patients who have difficulty swallowing are allowed to open the capsules immediately before taking and mix the contents with 1 teaspoon (no more) of applesauce.
The recommended dose is 400 mg (2 capsules of Tasigna 200 mg) 2 times a day.
If you miss the next appointment, you do not need to take a double dose, you should adhere to the standard treatment regimen.
Drug therapy is carried out as long as the clinical effect persists.
Before prescribing the drug, hypokalemia / hypomagnesemia, increased uric acid concentration and clinically significant dehydration (if any) should be corrected. Before taking Tasigna, after 7 days and periodically during treatment, an electrocardiogram (ECG) control is indicated. Also, during therapy, it is necessary to monitor the level of magnesium and potassium in the blood serum, especially in patients at risk of developing metabolic disorders.
Dose adjustment for neutropenia and thrombocytopenia
With Ph + CML in the chronic phase, in the case of a decrease in the absolute number of neutrophils <1 × 10 9 / L and / or the number of platelets <50 × 10 9 / L, Tasigna should be canceled and clinical blood tests should be performed. If within 2 weeks the number of neutrophils increases> 1 × 10 9 / L and / or platelets> 50 × 10 9 / L, the treatment is resumed at the dose used before the interruption of therapy. If cytopenia persists, a dose reduction to 400 mg once a day may be required.
With Ph + CML in the acceleration phase, in the case of a decrease in the absolute number of neutrophils <0.5 × 10 9 / L and / or the number of platelets <10 × 10 9 / L, Tasigna should be canceled and clinical blood tests should be performed. If within 2 weeks the number of neutrophils increases> 1 × 10 5 / l and / or platelets> 20 × 10 9 / l, treatment is resumed at the dose used before the interruption of therapy. If cytopenia persists, a dose reduction to 400 mg once a day may be required.
Dose adjustments for non-hematological side effects
If moderate or severe non-hematological reactions appear, Tasigna is canceled.
Treatment can be resumed after the disappearance of unwanted disorders, but at a dose of 400 mg 1 time per day. In the future, it is possible to increase the frequency of administration up to 2 times a day, 400 mg.
If the upper limit of the norm (UHN) of lipase activity in the blood is 2 times, the concentration of bilirubin is 3 times, or hepatic transaminases is 5 times, the dose of Tasigna should be reduced to 400 mg once a day or the drug should be temporarily interrupted.

Overdose
There are isolated reports of overdose cases. The patients took an unspecified number of capsules together with other drugs and alcohol. Symptoms such as vomiting, drowsiness, and neutropenia were noted. Signs of toxic liver damage and ECG changes were not observed.
In case of taking an excessive dose of Tasigna, careful monitoring of the patient's condition is required. Treatment is symptomatic.
special instructions
Treatment with Tasigna can only be performed by medical specialists with appropriate experience in the treatment of CML. Liver function (bilirubin and transaminase levels) should be monitored monthly.
Against the background of anticancer therapy, anemia, thrombocytopenia and neutropenia may develop (especially in patients with CML in the acceleration phase), therefore, a clinical blood test should be performed regularly: in the first two months - every 2 weeks, then - once a month or in case of clinical need … The resulting myelosuppression is usually manageable and reversible. To normalize the number of platelets and neutrophils, a reduction in the dose of Tasigna or a temporary discontinuation of the drug is often sufficient.
In case of an increase in the plasma activity of lipase, accompanied by abdominal symptoms, you should temporarily stop taking the drug and conduct an additional examination to exclude pancreatitis.
The bioavailability of nilotinib may be reduced in patients who have undergone gastrectomy, so treatment should be carried out under close medical supervision.
Approximately 0.1–1% of patients with heart disease or a high risk of cardiovascular complications have reported sudden deaths in clinical trials. All patients had concomitant diseases or were simultaneously receiving therapy with other drugs. An additional risk factor may be impaired ventricular repolarization. According to post-marketing research data, the frequency of spontaneous reports of sudden death cases per year per patient was 0.02%.
Influence on the ability to drive vehicles and complex mechanisms
During the period of anticancer therapy, side effects (for example, visual impairment, dizziness) may develop, which can have a negative effect on the ability to concentrate and speed of reactions. In this regard, patients receiving Tasigna are advised to exercise caution when driving and engaging in potentially hazardous activities.
Application during pregnancy and lactation
Tasigna is contraindicated during pregnancy and lactation.
During the period of drug treatment, men and especially women should use reliable methods of contraception.
Pediatric use
Tasigna is not prescribed for children and adolescents under 18 years of age, since there is no experience in treating patients of this age group with the drug.
With impaired renal function
Nilotinib and its metabolites are not excreted by the kidneys, therefore, in patients with renal insufficiency, a decrease in the total clearance of Tasigna is not expected.
For violations of liver function
In hepatic impairment, no dosage adjustment is required, but Tasigna should be used with caution.
Use in the elderly
There is no need to adjust the drug therapy regimen for elderly patients.
Drug interactions
When nilotinib was combined with ketoconazole (a strong inhibitor of the CYP3A4 isoenzyme), a 3-fold increase in the bioavailability of nilotinib was observed in healthy volunteers. In this regard, it is recommended to avoid the simultaneous administration of strong inhibitors of the isoenzyme CYP3A4 (including ketoconazole, voriconazole, itraconazole, telithromycin, clarithromycin, ritonavir). If necessary, consider the possibility of conducting alternative therapy with drugs that do not inhibit or slightly inhibit the specified isoenzyme. If the use of these drugs is necessary, it is recommended to suspend treatment with Tasigna. If temporary withdrawal is not possible, possible prolongation of the QTcF interval should be carefully monitored.
During the period of treatment with nilotinib, the use of grapefruit juice and other food products that are known inhibitors of the isoenzyme CYP3A4 should be avoided.
Inducers of the CYP3A4 isoenzyme (including St. John's wort, phenobarbital, phenytoin, carbamazepine, rifampicin) can increase the metabolism of nilotinib and, as a result, reduce its plasma concentration. For example, rifampicin (applied for 12 days at 600 mg per day) reduces systemic exposure of nilotinib by 80%. It is recommended to consider the possibility of prescribing other drugs that have less inducing effect on the specified isoenzyme.
Drugs affecting the P-glycoprotein and / or the CYP3A4 isoenzyme are capable of influencing the absorption and increasing the concentration of nilotinib in the blood plasma. In clinical studies of the combined use of nilotinib and imatinib, an increase in the AUC of nilotinib by 18-40%, and the AUC of imatinib by 18-39% was noted.
Tasigna should not be used in conjunction with antiarrhythmic drugs (such as disopyramide, sotalol, quinidine, procainamide, amiodarone) and other drugs that cause prolongation of the QT interval (such as haloperidol, clarithromycin, halofantrine, bepridil, pimozide, moxifloxacin, methadone), chloroquin.
With a single dose of Tasigna with midazolam in healthy individuals, an increase in the concentration of the latter by 30% was noted, however, the degree of its metabolism to the main metabolite (1-hydroxyimidazolam) did not change.
The solubility of nilotinib depends on the pH level, so when it rises, the solubility of the drug decreases. In healthy volunteers with a pronounced increase in pH due to the intake of esomeprazole (for 5 days, 40 mg once a day), the decrease in the absorption of nilotinib was moderate (a decrease in C max and AUC by 27 and 34%, respectively). If necessary, Tasigna can be used in combination with proton pump inhibitors.
There were no drug interactions with the simultaneous use of hematopoietic stimulants (such as erythropoietins and granulocyte colony-stimulating factor), anagrelide, hydroxycarbamide.
In healthy volunteers, nilotinib had no clinically significant effect on the pharmacological properties of warfarin.
When Tasigna is taken with food, the absorption of the drug increases, as a result of which its plasma concentration increases.

Reviews about Tasigna
Reviews about Tasigna are few, which, most likely, is due to the specifics of its application. Doctors indicate that nilotinib is the drug of choice for the treatment of chronic myeloid leukemia, especially in the case of ineffectiveness of previous therapy with Glivec. Tasigna is effective even with prolonged use, but it is generally hard to tolerate. Various adverse reactions are mentioned, including nausea, lack of appetite, dizziness, headache, pain in joints and bones, swelling, etc.
