Pharmacological properties

Pharmacodynamics

Uric acid is the end product of purine metabolism in the human body, formed as a result of a cascade of reactions hypoxanthine → xanthine → uric acid.

Febuxostat, the active substance of Adenuric, a derivative of 2-arylthiazole, is a potent selective non-purine inhibitor of xanthine oxidase (the in vitro inhibition constant of this enzyme is less than 1 nM). Xanthine oxidase catalyzes two stages of purine metabolism: the oxidation of hypoxanthine to xanthine, and then xanthine to uric acid.

The decrease in serum uric acid levels in the blood occurs due to the selective suppression of xanthine oxidase (oxidized and reduced forms) by febuxostat. In therapeutic concentrations, the active substance does not inhibit enzymes such as OPRT (orotate phosphoribosyltransferase), PNP (purine nucleoside phosphorylase), HGFRT (hypoxanthine guanine phosphoribosyltransferase), guanine deaminase, or orotidine boxyl monophosphate dextrose

The safety profile and clinical efficacy of febuxostat in the treatment of gout

The safety and efficacy of febuxostat has been documented in three pivotal phase III clinical trials (FACT, APEX, and CONFIRMS) in 4101 patients with gout and hyperuricemia. According to the results of these studies, Adenuric was more effective in lowering uric acid and maintaining serum uric acid levels when compared with allopurinol.

The 28-week APEX study included 1,072 patients. Patients received once a day: febuxostat in doses of 80, 120 or 240 mg; allopurinol at a dose of 300 mg (with an initial plasma creatinine level of ≤ 1.5 mg / dl) and at a dose of 100 mg (with an initial creatinine content of> 1.5 mg / dl and ≤ 2.0 mg / dl). Due to the use of febuxostat at doses of 120 mg and 80 mg once a day for 28 weeks, the number of patients whose serum uric acid content did not exceed 6 mg / dL (357 μmol / L) during the last 3 months was 65 and 48% accordingly, when using allopurinol - 22%.

760 patients participated in the double-blind, randomized 52-week FACT trial. When taking febuxostat 1 time per day at doses of 120 mg and 80 mg during the entire study period, the proportion of persons whose serum uric acid level did not exceed 6 mg / dL (357 μmol / L) during the last 3 months was 62 and 53%, respectively, and when using allopurinol once a day at a dose of 300 mg - 21%. The use of febuxostat provided a rapid decrease in blood plasma uric acid levels over a long period of time. A decrease in serum uric acid in the blood of less than 6 mg / dL (357 μmol / L) was recorded already in the second week of use (FACT study), this level of concentration was maintained throughout therapy with febuxostat.

In conducting a randomized controlled 26-week study CONFIRMS, 2269 patients were involved, at least 65% had mild to moderate renal impairment, with creatinine clearance (CC) of 30–89 ml / min. Due to the use of febuxostat once a day at a dose of 80 mg and 40 mg, the number of patients whose plasma level of uric acid was less than 6 mg / dL at the last visit to the doctor was 67 and 45%, respectively, for allopurinol at a daily dose of 300 mg and 200 mg - 42%.

The open-label, multicenter, randomized, extended safety study EXCEL compared with allopurinol included 1,086 individuals who completed the FACT or APEX study. The target serum uric acid level (less than 6.0 mg / dL), which was achieved against the background of previous administration of febuxostat, did not change over time - in 91 and 93% of patients initially receiving febuxostat at doses of 80 mg and 120 mg, uric acid concentration was less than 6 mg / dL at 36 months of treatment. According to the results of a three-year follow-up, a decrease in the incidence of gout attacks was recorded at 16-24 and 30-36 months, while more than 96% of patients did not need to treat gout attacks. In 46 and 38% of patients receiving the drug constantly 1 time per day, respectively,at a dose of 80 mg and 120 mg by the last visit, there was a complete disappearance of the initially palpable tophi.

A five-year, open-label, multicenter, extended safety study FOCUS (phase II) enrolled 116 patients initially treated with febuxostat 80 mg once daily for 4 weeks. No dose adjustments were required to maintain serum uric acid levels below 6 mg / dL in 62% of patients, and dose adjustments were required to achieve target levels in 38% of patients. At the last visit, the proportion of patients with a serum uric acid concentration of less than 6 mg / dL was more than 80% for each dose of febuxostat studied.

In a prospective analysis in the CONFIRMS study, febuxostat was found to be significantly more effective in reducing serum uric acid to less than 6 mg / dL compared to allopurinol 300 mg and 200 mg in patients with gout and mild to moderate renal failure. …

The safety profile and clinical efficacy of febuxostat in the treatment of tumor disintegration syndrome (TSS)

In a randomized, double-blind, phase III trial (FLORENCE), the safety and efficacy of febuxostat prophylaxis and therapy for FRO was studied. In the study, febuxostat showed a more intense and rapid decrease in serum uric acid levels compared to allopurinol, with no negative effect on renal function. The study involved 346 patients with hematological malignancies, who underwent cytostatic therapy, and who had a medium / high degree of threat of FRO. Evaluation of the effectiveness of Adenuric in maintaining the level of uric acid in the blood serum and the assessment of its effect on renal function was carried out against the background of taking once a day at a dose of 120 mg or using allopurinol at a daily dose of 200-600 mg. Patients participating in the study were required to receive allopurinol therapy or were not able to receive treatment with rasburicase.

The study found that the mean area under the concentration-time curve (AUC) over 8 days was significantly lower with Adenuric than with allopurinol. 24 hours after starting the course of treatment with febuxostat and in all further measurements, there was a significantly lower mean serum uric acid level compared with the allopurinol group. There were no statistically significant differences in the effect of febuxostat and allopurinol on plasma creatinine in the blood. Also, statistically significant differences in the incidence of FRO with the use of febuxostat and allopurinol were not recorded either by clinical criteria or by laboratory diagnostic criteria.

Pharmacokinetics

The population analysis of the pharmacokinetics / pharmacodynamics of Adenuric contains data obtained in a study involving 211 patients with hyperuricemia and gout who used the drug once a day in a dose range of 40–240 mg. The recorded values of the pharmacokinetic parameters of febuxostat corresponded to those in healthy volunteers, which allows the data of studies conducted with the participation of healthy volunteers to be considered representative of the population of patients with gout.

After oral administration, febuxostat is intensively and almost completely (not less than 84% of the administered dose) absorbed from the gastrointestinal tract (GIT). With repeated use of a dose of Adenuric 80 mg or with a single dose of 120 mg in combination with food rich in fats, its maximum plasma concentration (C _max) decreased by 49 and 38%, and AUC - by 18 and 16%, respectively. However, these reactions did not affect the decrease in serum uric acid levels in the blood (against the background of repeated use of febuxostat at a dose of 80 mg) and the clinical efficacy of the drug. Adenuric can thus be used regardless of the time of the meal.

After oral administration, C _max is observed after 1–1.5 hours and is 2.8–3.2 μg / ml with a single dose of Adenuric 80 mg, and 5–5.3 μg / ml at a dose of 120 mg. The absolute bioavailability of the active substance in tablet form has not been studied. In the case of a course of oral administration of the drug in the dose range of 10–240 mg once a day, cumulation was not observed.

With a single / multiple oral administration of Adenuric in healthy volunteers with increasing doses in the range from 10 to 120 mg C _max and AUC funds increase linearly, and in the dose range from 120 to 300 mg, an increase in AUC is observed to a greater extent than proportionate to the dose.

The apparent volume of distribution (V _d) at steady state after 10–300 mg of febuxostat can vary from 29 to 75 liters. The drug binds to plasma proteins (mostly albumin) by 99.2%. In this case, the degree of binding does not change in the case of increasing the dose from 80 to 120 mg. The connection of active metabolites with plasma proteins is 82–91%.

The metabolic transformation of febuxostat is carried out by conjugation with the participation of uridine diphosphate glucuronyl transferase (UDPGT) and oxidation under the action of enzymes of the cytochrome P _{450 system} (CYP). Four pharmacologically active hydroxyl metabolites of febuxostat have been identified, three of which are detected in human plasma. In the process of in vitro studies on liver microsomes, it was demonstrated that oxidized metabolites are formed mainly under the influence of isoenzymes CYP2C9, CYP2C8, CYP1A2 or CYP1A1, while febuxostat glucuronide is formed mainly due to the action of isoenzymes UGT1A9, UGT1A1 and UGT1A8.

The active substance and its metabolites are excreted from the body through the intestines and kidneys. After taking at a dose of 80 mg of ¹⁴ C- labeled febuxostat, approximately 49% is eliminated by the kidneys: in the form of acylglucuronide - 30%, in unchanged form - on average 3%, in the form of oxidized metabolites and their conjugates - 13%, in the form of other metabolites - 3 %. About 45% of febuxostat is excreted through the intestines: in the form of acylglucuronide - 1%, unchanged febuxostat - 12%, oxidized metabolites and their conjugates - 25% and other metabolites - 7%. The apparent half-life (T _1/2) of febuxostat can be 5–8 hours.

With the course use of febuxostat, its AUC and C _max in women were, respectively, 12 and 24% higher than in men. At the same time, the AUC and C _max values corrected for the patient's body weight were similar for both groups, as a result of which there is no need to change the dose of the agent depending on gender.

Indications for use

• chronic hyperuricemia in conditions leading to the deposition of urate crystals, including in the presence of tophus and / or gouty arthritis, including data in the anamnesis (treatment);
• hyperuricemia in adult patients receiving cytostatic therapy of hemoblastosis, with the threat of developing FRO from moderate to high - only for a dosage of 120 mg (prevention and treatment).

Contraindications

Absolute:

• malabsorption syndrome of glucose and galactose, lactase deficiency, hereditary galactose intolerance (Adenuric contains lactose);
• pregnancy and lactation;
• age up to 18 years;
• hypersensitivity to any of the constituents of the drug.

Relative (Adenuric tablets should be taken with extreme caution):

• congestive heart failure;
• ischemic heart disease (CHD);
• liver failure;
• renal failure of severe severity (CC below 30 ml / min);
• damage to the thyroid gland;
• Lesch-Nyhan syndrome (experience with the drug is limited);
• a history of allergic reactions;

Adenurik, instructions for use: method and dosage

Adenuric tablets are taken orally 1 time per day, regardless of the time of the meal.

For the treatment of gout, the drug is recommended to be used at an initial dose of 80 mg. After 2-4 weeks after the start of the course, the serum level of uric acid in the blood should be monitored, if this indicator exceeds 6 mg / dL (357 μmol / L), the dose of febuxostat can be increased to 120 mg. Monitoring the concentration of uric acid in serum can be carried out 2 weeks after the start of treatment with the drug, since Adenuric provides a fairly rapid decrease in its level. The goal of therapy is to reduce the content of uric acid in the blood serum and maintain it at a level below 6 mg / dL (357 μmol / L).

In order to prevent the occurrence of acute attacks of gout, the drug should be used for at least 6 months.

To prevent the development of hyperuricemia during cytostatic therapy of hemoblastosis with the threat of FRO and its treatment, it is recommended to start taking Adenuric 2 days before the start of the use of cytostatics. Prescribe tablets at a dosage of 120 mg, take them once a day. The course should be at least 1 week.

Taking into account the duration of chemotherapy, it is allowed to increase the duration of use of the anti-gout agent up to 9 days.

Notes

* Adverse reactions of Adenuric, recorded during post-marketing surveillance.

** Non-infectious diarrhea and liver side effects have been reported in phase III trials, and most often with colchicine and Adenuric.

Tumor collapse syndrome

During the study of FLORENCE therapy and prevention of hyperuricemia in adult patients receiving cytostatic therapy for hemoblastosis with a threat of FRO development, adverse events were recorded in 22 patients (6.4%). In patients from the febuxostat group and the allopurinol group, the incidence of adverse reactions was equal (11 patients each). In most cases, the side effects were mild / moderate. In total, apart from violations of the cardiovascular system in the form of hemorrhages, sinus tachycardia, left bundle branch block, there were no specific features of the drug safety profile in addition to that against the background of gout.

Overdose

Symptoms of an overdose of Adenuric may include an aggravation of the adverse reactions described above.

In this condition, symptomatic and supportive therapy is prescribed.

special instructions

Adenuric should be used only after an acute attack of gout has been removed. The initiation of drug treatment can cause an exacerbation of the disease as a result of the release of urate from tissue depots and a further increase in the serum concentration of uric acid in the blood. In order to prevent exacerbation of gout in the absence of contraindications, the drug should be combined with the use of non-steroidal anti-inflammatory drugs (NSAIDs) or colchicine for at least 6 months. If a gout attack occurs during the treatment with Adenuric, you should continue taking the drug and at the same time conduct appropriate treatment for its exacerbation. With prolonged use of the drug, the frequency and severity of attacks are reduced.

In patients with accelerated formation of urates (in particular, with Lesch-Nyhan syndrome or against the background of malignant tumors), in rare cases, there is a threat of a significant increase in the absolute concentration of xanthines in the urine, which can cause their deposition in the urinary tract. This phenomenon was not observed when using Adenuric in patients with FRO in the FLORENCE study.

Within the framework of post-marketing control, there were rare reports of the development of such serious hypersensitivity reactions as toxicodermal necrolysis, acute anaphylactic reactions / shock, Stevens-Johnson syndrome. Mainly these complications occurred during the first month of drug treatment. Some patients had indications of a history of renal dysfunction and / or hypersensitivity reactions to allopurinol. Severe hypersensitivity reactions in some cases were accompanied by changes in blood counts, fever, functional disorders of the liver or kidneys. Patients need to be aware of possible symptoms and signs of hypersensitivity reactions and be monitored for the development of symptoms of these complications. If serious responses to therapy develop,it is necessary to immediately stop taking Adenuric, since early termination of its use improves the prognosis. In these cases, re-administration of febuxostat is contraindicated.

Patients who are on cytostatic therapy of hemoblastoses with the threat of developing FRO from a moderate to severe degree, in the presence of clinical manifestations from the heart while using Adenuric, need careful monitoring by a cardiologist.

In the course of long-term open studies with prolonged use of febuxostat, an increase in TSH level (> 5.5 μIU / ml) was recorded in 5.5% of patients, therefore, patients with functional disorders of the thyroid gland should take Adenuric with caution.

In line with the pooled data from phase III clinical trials, mild liver dysfunctions were observed in 5% of patients with febuxostat. Before starting treatment with Adenuric, the liver function should be assessed, and if there are clinical manifestations, it should be monitored periodically during the use of the drug.

Influence on the ability to drive vehicles and complex mechanisms

During therapy with febuxostat, there is a risk of dizziness, drowsiness, blurred vision and paresthesia, which can lead to a decrease in reaction and ability to concentrate. Given the likelihood of developing adverse events, patients taking Adenuric should exercise caution when driving vehicles and operating other complex and potentially dangerous machinery.

Application during pregnancy and lactation

Taking Adenuric during pregnancy is contraindicated due to insufficient data on the possible risk of therapy with febuxostat during this period for humans. According to the limited experience of using the drug in pregnant women, its adverse effects on pregnancy and fetal / newborn health have not been recorded. In the course of preclinical studies on animals, both direct and indirect negative effects on the course of pregnancy, the process of childbirth and the development of the embryo / fetus were not observed.

It is not known whether febuxostat is excreted in human milk. In animals, the penetration of the substance into breast milk was established and its adverse effect on the development of fed young was established. Due to the existing risk of excretion of the drug in breast milk, Adenuric is contraindicated for use during lactation.

Pediatric use

Adenuric is not intended for use in pediatric practice.

With impaired renal function

In the presence of mild / moderate renal failure, individual selection of doses of the drug is not required. In patients with severely impaired renal function (CC <30 ml / min), the safety and efficacy of using Adenuric have not been studied enough, and therefore it is recommended to use it with extreme caution.

For violations of liver function

In the treatment of gout against the background of mild liver failure - class A on the Child-Pugh scale (5-6 points), it is recommended to take febuxostat in a daily dose of 80 mg. In patients with moderate liver dysfunction, the experience of using Adenuric is limited.

In clinical trials of FLORENCE, with the threat of FRO development, it was not required to adjust the dose of Adenuric depending on liver activity (these studies did not include patients with severe hepatic insufficiency).

The efficacy and safety of treatment with febuxostat in patients with severe class C liver dysfunction according to the Child-Pugh scale (10-15 points) has not been studied.

Use in the elderly

In elderly people, when compared with young volunteers against the background of repeated administration of febuxostat, there were no significant changes in the AUC of the drug and its metabolites. Elderly patients do not need individual selection of doses of Adenuric.

Drug interactions

• cytostatics: studies on the interaction of these agents with febuxostat have not been carried out, as a result of this, the possible interaction of the latter with simultaneously used cytotoxic drugs cannot be ruled out;
• theophylline: there were no changes in the pharmacokinetic parameters or tolerability of this substance when it was used in a single dose of 400 mg in combination with febuxostat in a daily dose of 80 mg; this combined use does not require special precautions; concomitant use of theophylline with febuxostat 120 mg has not been studied;
• rosiglitazone and other substrates of the isoenzyme CYP2C8: no change in the dose of these agents and Adenuric is required; according to in vitro data, febuxostat belongs to weak inhibitors of the isoenzyme CYP2C8, when taken at a dose of 120 mg per day and rosiglitazone in a single dose of 4 mg, no changes in the pharmacokinetic characteristics of rosiglitazone and its metabolite N-dismethyl rosiglitazone were recorded;
• inhibitors of glucuronidation, including naproxen: there was an increase in AUC, C _max and T _{1/2 of} febuxostat by 41, 28 and 26%, respectively, when the latter was combined with naproxen at a dose of 250 mg twice a day; drugs that inhibit the glucuronidation process, such as probenecid and NSAIDs, are theoretically able to influence the excretion of febuxostat; in the course of studies, the simultaneous use of febuxostat and naproxen or other NSAIDs / inhibitors of cyclooxygenase-2 (COX-2) did not lead to a clinically significant increase in the frequency of side effects; with this combination, there is no need to adjust the doses of drugs;
• colchicine / hydrochlorothiazide / indomethacin: there is no need to change the dose of Adenuric during combination therapy;
• warfarin: no effect on INR (international normalized ratio), factor VII activity and pharmacokinetics of warfarin when used in combination with febuxostat at a dose of 80 or 120 mg per day; dose adjustment of warfarin with this combination is not carried out;
• powerful inducers of glucuronidation: it is possible to increase the metabolic transformation of febuxostat and reduce its effectiveness; 1–2 weeks after the start of combination therapy, it is necessary to control the serum level of uric acid in the blood; if the glucuronidation inducer is canceled, an increase in C _{max of} febuxostat may be observed;
• substrates of the CYP2D6 isoenzyme (including desipramine): febuxostat, according to data obtained in vitro, refers to weak inhibitors of the CYP2D6 isoenzyme; while taking febuxostat in a daily dose of 120 mg, an increase in the AUC of desipramine by 22% was recorded, which is evidence of the weak inhibitory effect of febuxostat in vivo on the isoenzyme CYP2D6; no dose adjustment of the substrates of this isoenzyme and Adenuric is required;
• antacids (containing magnesium / aluminum hydroxide): there was a decrease in the absorption of febuxostat by about 1 hour and a decrease in C _max by 32%, while the AUC of the agent did not change significantly; taking Adenuric can be combined with taking antacids.
