Como funciona

12.1 Mechanism of Action Tacrolimus binds to an intracellular protein, FKBP-12. A complex of tacrolimus-FKBP-12, calcium, calmodulin, and calcineurin (a ubiquitous mammalian intracellular enzyme) is then formed and the phosphatase activity of calcineurin is inhibited. Such inhibition prevents the dephosphorylation and translocation of various factors such as the nuclear factor of activated T-cells (NF-AT), and nuclear factor kappa-light-chain-enhancer of activated B-cells (NF-κB). Tacrolimus inhibits the expression and/or production of several cytokines that include interleukin (IL)-1 beta, IL‑2, IL-3, IL-4, IL-5, IL-6, IL-8, IL-10, gamma interferon, tumor necrosis factor-alpha, and granulocyte macrophage colony-stimulating factor. Tacrolimus also inhibits IL-2 receptor expression and nitric oxide release, induces apoptosis and production of transforming growth factor-beta that can lead to immunosuppressive activity. The net result is the inhibition of T-lymphocyte activation and proliferation as well as T-helper-cell-dependent B-cell response (i.e., immunosuppression).

MMF = Mycophenolate mofetil Recommended Tacrolimus Extended-Release Capsules Initial Dosage Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 mg/kg to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant Month 1: 7 ng/mL to 15 ng/mL Month 2 to Month 6: 5 ng/mL to 15 ng/mL More than 6 Months: 5 ng/mL to 10 ng/mL With MMF and steroids, without basiliximab induction First dose (pre-operative): 0.1 mg/kg, within 12 hours prior to reperfusion Subsequent doses (post-operative): 0.2 mg/kg once daily at least 4 hours after pre-operative dose and within 12 hours after reperfusion Month 1: 10 ng/mL to 15 ng/mL Month 2 to Month 6: 5 ng/mL to 15 ng/mL More than 6 Months: 5 ng/mL to 10 ng/mL 2.1 Important Administration Instructions Tacrolimus extended-release capsules should not be used without the supervision by a physician with experience in immunosuppressive therapy. Tacrolimus extended-release capsules is not interchangeable or substitutable for tacrolimus extended-release tablets, tacrolimus immediate-release capsules or tacrolimus for oral suspension. Under or overexposure to tacrolimus may result in graft rejection or other serious adverse reactions. Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision [see Warnings and Precautions ( 5.4 )]. Advise patients to swallow tacrolimus extended-release capsules whole with liquid; patients must not chew, divide, or crush the capsules. Tacrolimus extended-release capsules should be taken consistently every morning at the same time to ensure consistent and maximum possible drug exposure, on an empty stomach at least 1 hour before a meal, or at least 2 hours after a meal [see Clinical Pharmacology ( 12.3 )]. If a dose is missed, the dose may be taken up to 14 hours after the scheduled time (i.e., for a missed 8:00 AM dose, a dose may be taken by 10:00 PM). Beyond the 14-hour time frame, the patient should wait until the usual scheduled time the following morning to take the next regular daily dose. Instruct the patient not to double the next dose. Advise patients to avoid eating grapefruit or drinking grapefruit juice or alcoholic beverages while taking tacrolimus extended-release capsules [see Drug Interactions ( 7.2 )]. Therapeutic drug monitoring is recommended for all patients receiving tacrolimus extended-release capsules [see Dosage and Administration ( 2.4 )] . 2.2 Dosage Recommendations for Kidney Transplant Patients Table 1 includes the recommended starting tacrolimus extended-release capsules dosages and whole blood trough concentration ranges; the observed trough concentrations are shown in another section of the Full Prescribing Information [see Clinical Studies ( 14 )] . Titrate the tacrolimus extended-release capsules dosage based on clinical assessments of rejection and tolerability, and to achieve target trough concentration ranges [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.6 , 5.7 , 5.10 , 5.11 )] . Table 1: Recommended Starting Daily Dosage Regimen of Tacrolimus Extended-Release Capsules MMF = mycophenolate mofetil Recommended Tacrolimus Extended-Release Capsules Initial Dosage* Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 mg/kg to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant • Month 1: 7 ng/mL to 15 ng/mL • Month 2 to Month 6: 5 ng/mL to 15 ng/mL • More than 6 Months: 5 ng/mL to 10 ng/mL With MMF and steroids, without basiliximab induction • First dose (pre-operative): 0.1 mg/kg, within 12 hours prior to reperfusion • Subsequent doses (post-operative): 0.2 mg/kg once daily at least 4 hours after pre-operative dose and within 12 hours after reperfusion • Month 1: 10 ng/mL to 15 ng/mL • Month 2 to Month 6: 5 ng/mL to 15 ng/mL • More than 6 Months: 5 ng/mL to 10 ng/mL Pediatric use information is approved for Astellas Pharma US, Inc.'s ASTAGRAF XL (tacrolimus extended-release capsules). However, due to Astellas Pharma US, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 2.3 Dosage Modifications for African-American Patients, Patients with Hepatic Impairment, and Drug Interactions African-American patients, compared to Caucasian patients, may need to be titrated to higher tacrolimus extended-release capsules dosages to attain comparable trough concentrations [see Clinical Pharmacology ( 12.3 ) and Clinical Studies ( 14 )] . Patients with severe hepatic impairment (Child-Pugh ≥ 10) may require a lower starting dosage of tacrolimus extended-release capsules, due to the reduced clearance and prolonged half-life [see Clinical Pharmacology ( 12.3 )]. Dose adjustments of tacrolimus extended-release capsules may be necessary when administered concomitantly with CYP3A inducers or CYP3A inhibitors or cannabidiol [see Warnings and Precautions ( 5.10 , 5.15 ) and Drug Interactions ( 7.2 , 7.3 )]. 2.4 Therapeutic Drug Monitoring Measure tacrolimus whole blood trough concentrations at least two times on separate days during the first week after initiation of dosing and after a change in dosage, after a change in co-administration of CYP3A4 inducers and/or inhibitors or cannabidiol [see Drug Interactions (7.2 , 7.3 )] , or after a change in renal or hepatic function. When interpreting measured concentrations, consider that the time to achieve tacrolimus steady state is approximately 7 days after initiating or changing the tacrolimus extended-release capsules dose. Monitor tacrolimus whole blood trough concentrations using a validated assay [e.g., immunoassays or high performance liquid chromatography with tandem mass spectrometric detection (HPLC/MS/MS)]. The immunosuppressive activity of tacrolimus is mainly due to the parent drug rather than to its metabolites. Immunoassays may react with metabolites as well as the parent drug. Therefore, whole blood tacrolimus trough concentrations obtained with immunoassays may be numerically higher than concentrations obtained with an assay using HPLC/MS/MS. Comparison of the whole blood tacrolimus trough concentrations of patients to those described in the prescribing information and other published literature must be made with knowledge of the assay method(s) employed.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact eVenus Pharmaceutical Laboratories, Inc. at 1-609-395-8625 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In addition, the clinical trials were not designed to establish comparative differences across study arms with regards to the adverse reactions discussed below. Kidney transplant patients were treated with tacrolimus extended-release capsules (N=214) or tacrolimus immediate-release product (N=212) and concomitant immunosuppressants (median duration of exposure of 12 months) in a randomized, open-label, active-controlled trial of mostly U.S. patients (Study 1) [see Clinical Studies ( 14.1 )] . The types of adverse reactions seen in Study 1 were similar to the adverse reactions seen in Study 2 [non-U.S. trial in kidney transplant patients treated with tacrolimus extended-release capsules (N=331) or tacrolimus immediate-release product (N=336) and concomitant immunosuppressants] [see Clinical Studies ( 14.2 )] . In Study 1, the proportion of patients who discontinued treatment due to adverse reactions was 9% and 11% in the tacrolimus extended-release capsules and tacrolimus immediate-release treatment groups, respectively, through 12 months of treatment. The most common adverse reactions leading to discontinuation in tacrolimus extended-release capsules-treated patients were related to infections or renal/urinary disorders. Infections The overall incidence of infections, serious infections, and infections with identified etiology reported in patients treated with the tacrolimus extended-release capsules or tacrolimus immediate-release product in Study 1 are shown in Table 2 . Table 2: Percentage of Patients with Infections in Study 1 Study 1 was not designed to support comparative claims of tacrolimus extended-release capsules compared to tacrolimus immediate-release product for the adverse reactions reported in this table.

5 WARNINGS AND PRECAUTIONS Not Interchangeable with Other Tacrolimus Products-Medication Errors: Instruct patients or caregivers to recognize the appearance of tacrolimus extended-release capsules. ( 5.4 ) New onset diabetes after transplant: Monitor blood glucose. ( 5.5 ) Nephrotoxicity (acute and/or chronic): May occur due to tacrolimus extended-release capsules, drug interactions, concomitant nephrotoxic drugs. Monitor renal function; consider dosage reduction. ( 5.6 ) Neurotoxicity: Including risk of posterior reversible encephalopathy syndrome (PRES), monitor for neurologic abnormalities; reduce dosage or discontinue tacrolimus extended-release capsules. ( 5.7 ) Hyperkalemia: Risk may be increased with other agents associated with hyperkalemia; monitor serum potassium levels. ( 5.8 ) Hypertension: May require antihypertensive therapy; monitor relevant drug interactions. ( 5.9 ) QT prolongation: Consider obtaining electrocardiograms and monitoring electrolytes in patients at high risk. ( 5.11 ) Immunizations: Avoid live vaccines. ( 5.12 ) Pure red cell aplasia: Consider discontinuation of tacrolimus extended-release capsules. ( 5.13 ) Thrombotic Microangiopathy, Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura: May occur, especially in patients with infections and certain concomitant medications. ( 5.14 ) 5.1 Lymphoma and Other Malignancies Immunosuppressants, including tacrolimus extended-release capsules, increase the risk of developing lymphomas and other malignancies, particularly of the skin . The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. Examine patients for skin changes and advise to avoid or limit exposure to sunlight and UV light by wearing protective clothing and using a broad-spectrum sunscreen with a high protection factor. Post-transplant lymphoproliferative disorder (PTLD), associated with Epstein-Barr Virus (EBV), has been reported in immunosuppressed organ transplant patients. The risk of PTLD appears greatest in patients who are EBV seronegative, a population which includes many young children. Monitor EBV serology during treatment. 5.2 Serious Infections Immunosuppressants, including tacrolimus extended-release capsules, increase the risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections. These infections may lead to serious, including fatal, outcomes. Serious viral infections reported include: Polyomavirus-associated nephropathy (especially due to BK virus infection) JC virus-associated progressive multifocal leukoencephalopathy (PML) Cytomegalovirus (CMV) infections: CMV seronegative transplant patients who receive an organ from a CMV seropositive donor are at highest risk of CMV viremia and CMV disease. Monitor for the development of infection and adjust the immunosuppressive regimen to balance the risk of rejection with the risk of infection [see Adverse Reactions ( 6.1 , 6.2 )] . 5.3 Increased Mortality in Female Liver Transplant Patients In a clinical trial of 471 liver transplant patients randomized to tacrolimus extended-release capsules or tacrolimus immediate-release product, mortality at 12 months was 10% higher among the 76 female patients (18%) treated with tacrolimus extended-release capsules compared to the 64 female patients (8%) treated with tacrolimus immediate-release product. Tacrolimus extended-release capsules is not approved for the prophylaxis of organ rejection in patients who received a liver transplant. 5.4 Not Interchangeable with Other Tacrolimus Products - Medication Errors Medication errors, including substitution and dispensing errors, between tacrolimus immediate-release products and tacrolimus extended-release capsules were reported outside the U.S. This led to serious adverse reactions, including graft rejection, or other adverse reactions due to under- or over-exposure to tacrolimus. Tacrolimus extended-release capsules is not interchangeable or substitutable for tacrolimus extended-release tablets, tacrolimus immediate-release capsules or tacrolimus for oral suspension. Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision. Instruct patients and caregivers to recognize the appearance of tacrolimus extended-release capsules [see Dosage Forms and Strengths ( 3 )] and to confirm with the healthcare provider if a different product is dispensed or if dosing instructions have changed. 5.5 New Onset Diabetes After Transplant Tacrolimus extended-release capsules caused new onset diabetes after transplant (NODAT) in kidney transplant patients, which may be reversible in some patients. African-American and Hispanic kidney transplant patients are at an increased risk. Monitor blood glucose concentrations and treat appropriately [see Adverse Reactions ( 6.1 ) and Use in Specific Populations ( 8.8 )] . 5.6 Nephrotoxicity due to Tacrolimus Extended-Release Capsules and Drug Interactions Tacrolimus extended-release capsules, like other calcineurin-inhibitors, can cause acute or chronic nephrotoxicity in transplant patients due to its vasoconstrictive effect on renal vasculature, toxic tubulopathy and tubular-interstitial effects. Acute renal impairment associated with tacrolimus toxicity can result in high serum creatinine, hyperkalemia, decreased secretion of urea and hyperuricemia, and is usually reversible. In patients with elevated serum creatinine and tacrolimus whole blood trough concentrations greater than the recommended range, consider dosage reduction or temporary interruption of tacrolimus administration. The risk for nephrotoxicity may increase when tacrolimus extended-release capsules is concomitantly administered with CYP3A inhibitors (by increasing tacrolimus whole blood concentrations) or drugs associated with nephrotoxicity (e.g., aminoglycosides, ganciclovir, amphotericin B, cisplatin, nucleotide reverse transcriptase inhibitors, protease inhibitors). When tacrolimus is used concurrently with other known nephrotoxic drugs, monitor renal function and tacrolimus blood concentrations, and adjust dose of both tacrolimus and/or concomitant medications during concurrent use [see Adverse Reactions ( 6.1 , 6.2 ) and Drug Interactions ( 7.2 )]. 5.7 Neurotoxicity Tacrolimus extended-release capsules may cause a spectrum of neurotoxicities. The most severe neurotoxicities include posterior reversible encephalopathy syndrome (PRES), delirium, seizure and coma; others include tremors, paresthesias, headache, mental status changes, and changes in motor and sensory functions [see Adverse Reactions ( 6.1 , 6.2 )] . As symptoms may be associated with tacrolimus whole blood trough concentrations at or above the recommended range, monitor for neurologic symptoms and consider dosage reduction or discontinuation of tacrolimus extended-release capsules if neurotoxicity occurs. 5.8 Hyperkalemia Mild to severe hyperkalemia, which may require treatment, has been reported with tacrolimus including tacrolimus extended-release capsules. Concomitant use of agents associated with hyperkalemia (e.g., potassium-sparing diuretics, ACE inhibitors, angiotensin receptor blockers) may increase the risk for hyperkalemia [see Adverse Reactions ( 6.1 )] . Monitor serum potassium levels periodically during treatment. 5.9 Hypertension Hypertension is a common adverse reaction of tacrolimus extended-release capsules therapy and may require antihypertensive therapy [see Adverse Reactions ( 6.1 )] . Some antihypertensive drugs can increase the risk for hyperkalemia [see Warnings and Precautions ( 5.8 )] . Calcium-channel blocking agents may increase tacrolimus blood concentrations and require dosage reduction of tacrolimus extended-release capsules [see Drug Interactions ( 7.2 )] . 5.10 Risk of Rejection with Strong CYP3A Inducers and Risk of Serious Adverse Reactions with Strong CYP3A Inhibitors The concomitant use of strong CYP3A inducers may increase the metabolism of tacrolimus, leading to lower whole blood trough concentrations and greater risk of rejection. In contrast, the concomitant use of strong CYP3A inhibitors may decrease the metabolism of tacrolimus, leading to higher whole blood trough concentrations and greater risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.11 )] . Therefore, adjust tacrolimus extended-release capsules dose and monitor tacrolimus whole blood trough concentrations when co-administering tacrolimus extended-release capsules with strong CYP3A inhibitors (e.g., including, but not limited to, telaprevir, boceprevir, ritonavir, ketoconazole, itraconazole, voriconazole, clarithromycin) or strong CYP3A inducers (e.g., including, but not limited to, rifampin, rifabutin) [see Dosage and Administration ( 2.4 ) and Drug Interactions ( 7.2 )] . A rapid, sharp rise in tacrolimus levels has been reported after co-administration with a strong CYP3A4 inhibitor, clarithromycin, despite an initial reduction of tacrolimus dose. Early and frequent monitoring of tacrolimus whole blood trough levels is recommended [see Drug Interactions (7.2) ] . 5.11 QT Prolongation Tacrolimus extended-release capsules may prolong the QT/QTc interval and cause Torsades de pointes . Avoid tacrolimus extended-release capsules in patients with congenital long QT syndrome. Consider obtaining electrocardiograms and monitoring electrolytes (magnesium, potassium, calcium) periodically during treatment in patients with congestive heart failure, bradyarrhythmias, those taking certain antiarrhythmic medications or other products that lead to QT prolongation, and those with electrolyte disturbances (e.g., hypokalemia, hypocalcemia, or hypomagnesemia). When co-administering tacrolimus extended-release capsules with other substrates and/or inhibitors of CYP3A, especially those that also have the potential to prolong the QT interval, a reduction in tacrolimus extended-release capsules dosage, monitoring of tacrolimus whole blood concentrations, and monitoring for QT prolongation is recommended [see Dosage and Administration ( 2.4 ) and Drug Interactions ( 7.2 )] . 5.12 Immunizations Whenever possible, administer the complete complement of vaccines before transplantation and treatment with tacrolimus extended-release capsules. Avoid the use of live attenuated vaccines during treatment with tacrolimus extended-release capsules (e.g., intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella, and TY21a typhoid vaccines). Inactivated vaccines noted to be safe for administration after transplantation may not be sufficiently immunogenic during treatment with tacrolimus extended-release capsules. 5.13 Pure Red Cell Aplasia Cases of pure red cell aplasia (PRCA) have been reported in patients treated with tacrolimus. All of these patients reported risk factors for PRCA such as parvovirus B19 infection, underlying disease, or concomitant medications associated with PRCA. A mechanism for tacrolimus-induced PRCA has not been elucidated. If PRCA is diagnosed, consider discontinuation of tacrolimus extended-release capsules. 5.14 Thrombotic Microangiopathy (TMA) Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura Cases of thrombotic microangiopathy (TMA), including hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP), have been reported in patients treated with tacrolimus extended-release capsules TMA may have a multifactorial etiology. Risk factors for TMA that can occur in transplant patients include, for example, severe infections, graft-versus-host disease (GVHD), Human Leukocyte Antigen (HLA) mismatch, the use of calcineurin inhibitors and mammalian target of rapamycin (mTOR) inhibitors. These risk factors may, either alone or combined, contribute to the risk of TMA. In patients with signs and symptoms of TMA, consider tacrolimus as a risk factor. Concurrent use of tacrolimus and mTOR inhibitors may contribute to the risk of TMA. 5.15 Cannabidiol Drug Interactions When cannabidiol and tacrolimus extended-release capsules are co-administered, closely monitor for an increase in tacrolimus blood levels and for adverse reactions suggestive of tacrolimus toxicity. A dose reduction of tacrolimus extended-release capsules should be considered as needed when tacrolimus extended-release capsules is co-administered with cannabidiol [see Dosage and Administration (2.4) and Drug Interactions (7.3) ] .

12.3 Pharmacokinetics Table 7 summarizes the pharmacokinetic (PK) parameters of tacrolimus following oral administration of tacrolimus extended-release capsules in healthy subjects and in kidney transplant patients. Whole blood tacrolimus concentrations in these PK studies were measured using validated HPLC/MS/MS assays. Table 7: Pharmacokinetic Parameters of Tacrolimus Extended-Release Capsules (Given Once Daily) in Healthy Subjects and in Kidney Transplant Patients (Under Fasted Conditions) Population Tacrolimus Extended-Release Capsules Dose Healthy adult subjects (actual administered dose of tacrolimus extended-release capsules); adult de novo kidney transplant patients (actual group mean dose of tacrolimus extended-release capsules). Day Day of tacrolimus extended-release capsules treatment and PK profiling. PK Parameters of Tacrolimus Extended-Release Capsules C max Arithmetic means ± S.D. (ng/mL) T max Median [range].

Day 14 16.1 ± 5.3 2 [1 to 6] 222 ± 64 6.7 ± 1.9 Correlation coefficient of AUC 24 to C min r = 0.88. In de novo adult kidney transplant patients, the tacrolimus systemic exposure, as assessed by AUC 24 , for tacrolimus extended-release capsules 0.2 mg/kg once daily on Day 1 post-transplant was 18% (Ratio [SD]: 0.822 [1.647]) lower when compared with Prograf (tacrolimus immediate-release) 0.2 mg/kg/day given twice daily. By Day 3 post-transplant, the AUC 24 was similar between the two formulations. On Day 14 (steady state), the AUC 24 for tacrolimus extended-release capsules was 21% (Ratio [SD]: 1.207 [1.326]) higher than that of Prograf (tacrolimus immediate-release), at comparable trough concentrations (C 24 ). Due to intersubject variability in tacrolimus PK, individualization of dosing regimen is necessary for optimal therapy [see Dosage and Administration ( 2.3 , 2.4 )] . Pharmacokinetic data indicate that whole blood concentrations rather than plasma concentrations serve as the more appropriate sampling compartment to describe tacrolimus PK. Absorption In healthy subjects, the administration of escalating tacrolimus extended-release capsules doses ranging from 1.5 mg to 10 mg resulted in dose-proportional increases in tacrolimus AUC and C 24h , and no change in elimination half-life. Food Effects The presence of a meal affects the absorption of tacrolimus; the rate and extent of absorption is greatest under fasted conditions. In 24 healthy subjects, administration of tacrolimus extended-release capsules immediately following a high-fat meal (150 protein calories, 250 carbohydrate calories, and 500 to 600 fat calories) reduced the C max , AUC t , and AUC inf of tacrolimus by approximately 25% compared with fasting values. Food delayed the median T max from 2 hours in the fasted state to 4 hours in the fed state; however, the terminal half-life remained 36 hours regardless of dosing conditions. The time when a meal is consumed also affected tacrolimus bioavailability. In 24 healthy subjects, when tacrolimus extended-release capsules was administered 1.5 hours after consumption of a high-fat breakfast, tacrolimus exposure was decreased approximately 35%. Administration of tacrolimus extended-release capsules 1 hour prior to a high-fat breakfast reduced tacrolimus exposure by 10%. Tacrolimus extended-release capsules should be taken, preferably on an empty stomach, at least 1 hour before a meal or at least 2 hours after a meal. Chronopharmacokinetic Effect In 23 healthy subjects, a diurnal effect on the absorption of tacrolimus was observed. Evening dosing of tacrolimus extended-release capsules reduced AUC inf by 35% relative to morning dosing. Tacrolimus extended-release capsules should be taken consistently at the same time every morning. Distribution The plasma protein binding of tacrolimus is approximately 99% and is independent of concentration over a range of 5 ng/mL to 50 ng/mL. Tacrolimus is bound mainly to albumin and alpha-1-acid glycoprotein, and has a high level of association with erythrocytes. The distribution of tacrolimus between whole blood and plasma depends on several factors, such as hematocrit, temperature at the time of plasma separation, drug concentration, and plasma protein concentration. In a U.S. trial in which tacrolimus was administered as tacrolimus immediate-release, the ratio of whole blood concentration to plasma concentration averaged 35 (range 12 to 67). Elimination Metabolism The desired pharmacological activity of tacrolimus is primarily due to the parent drug. Tacrolimus is extensively metabolized by the mixed-function oxidase system, primarily the cytochrome P-450 system (CYP3A4 and CYP3A5). A metabolic pathway leading to the formation of 8 possible metabolites has been proposed. Demethylation and hydroxylation were identified as the primary mechanisms of biotransformation in vitro . The major metabolite identified in incubations with human liver microsomes is 13-demethyl tacrolimus. In in vitro studies, a 31-demethyl metabolite has been reported to have the same activity as tacrolimus. Excretion In a mass balance study of orally-administered radiolabeled tacrolimus to 6 healthy subjects, the mean recovery of the radiolabel was 94.9 ± 30.7%. Fecal elimination accounted for 92.6 ± 30.7% and urinary elimination accounted for 2.3 ± 1.1% of the total radiolabel administered. The elimination half-life based on radioactivity was 31.9 ± 10.5 hours, whereas it was 48.4 ± 12.3 hours based on tacrolimus concentrations. The mean clearance of radiolabel was 0.226 ± 0.116 L/hr/kg and the mean clearance of tacrolimus was 0.172 ± 0.088 L/hr/kg. The elimination half-life of tacrolimus after oral administration of 4 mg tacrolimus extended-release capsules daily for 10 days was 38 ± 3 hours in 24 healthy subjects.

However, due to Astellas Pharma US, Inc.’s marketing exclusivity rights, this drug product is not labeled with that information. Patients with Renal Impairment Tacrolimus pharmacokinetics following a single administration of tacrolimus immediate-release injection (administered as a continuous IV infusion) were determined in 12 patients (7 not on dialysis and 5 on dialysis, serum creatinine of 3.9 ± 1.6 and 12 ± 2.4 mg/dL, respectively) prior to their kidney transplant. The mean clearance of tacrolimus in patients with renal dysfunction given tacrolimus IV was similar to that in healthy subjects given tacrolimus IV and in healthy subjects given oral tacrolimus immediate-release [see Use in Specific Populations ( 8.6 )] . Patients with Hepatic Impairment Tacrolimus pharmacokinetics have been determined in six patients with mild hepatic impairment (mean Child-Pugh score: 6.2) following single oral administration of tacrolimus immediate-release. The mean clearance of tacrolimus in patients with mild hepatic impairment was not substantially different from that in healthy subjects. Tacrolimus pharmacokinetics were studied in six patients with severe hepatic impairment (mean Child-Pugh score: more than 10). The mean clearance was substantially lower in patients with severe hepatic impairment [see Dosage and Administration ( 2.3 ) and Use in Specific Populations ( 8.7 )]. Racial or Ethnic Groups The pharmacokinetics of tacrolimus was studied following single oral administration of tacrolimus immediate-release (5 mg) in 10 African-American, 12 Latino-American, and 12 Caucasian healthy subjects [see Dosage and Administration ( 2.2 ), Use in Specific Populations ( 8.8 ) and Clinical Studies ( 14 )]: The mean (± SD) tacrolimus C max in African-Americans (23.6 ± 12.1 ng/mL) was lower than in Caucasians (40.2 ± 12.6 ng/mL) and Latino-Americans (36.2 ± 15.8 ng/mL). Mean AUC 0-inf tended to be lower in African-Americans (203 ± 115 ng∙hr/mL) than Caucasians (344 ± 186 ng∙hr/mL) and Latino-Americans (274 ± 150 ng∙hr/mL). The mean (± SD) absolute oral bioavailability (F) in African-Americans (12 ± 4.5%) and Latino-Americans (14 ± 7.4%) was lower than in Caucasians (19 ± 5.8%). There was no significant difference in mean terminal half-life among the three ethnic groups (range from approximately 25 to 30 hours). Male and Female Patients A formal trial to evaluate the effect of gender on tacrolimus pharmacokinetics has not been conducted; however, there was no difference in total mg daily dosages between male and female patients receiving tacrolimus extended-release capsules in the kidney transplant trials. A retrospective comparison of pharmacokinetics in healthy subjects, and in kidney transplant patients indicated no gender-based differences. Drug Interaction Studies Because tacrolimus is metabolized mainly by CYP3A enzymes, drugs or substances known to inhibit these enzymes and/or are known CYP3A substrates may increase tacrolimus whole blood concentrations. Drugs known to induce CYP3A enzymes may decrease tacrolimus whole blood concentrations [see Warnings and Precautions ( 5.10 ) and Drug Interactions ( 7.2 )] . Figure 1 and Figure 2 summarize the PK data from drug interaction studies of tacrolimus extended-release capsules or tacrolimus immediate-release capsules. These studies assessed the effect of co-administered drugs on tacrolimus PK in healthy subjects. Dosing adjustments, when using drugs that inhibit or increase CYP3A enzymes, may be necessary [ see Drug Interactions ( 7.2 )] . Figure 1: Effect of Co-administered Drugs on the Pharmacokinetics of Tacrolimus (when Given as Tacrolimus Extended-Release Capsules) Figure 2: Effect of Co-administered Drugs on the Pharmacokinetics of Tacrolimus (when Given as Immediate-Release Tacrolimus) Other Drug Interaction Studies Caspofungin (see complete prescribing information for CANCIDAS): Caspofungin reduced the blood AUC 0-12 of tacrolimus by approximately 20%, peak blood concentration (C max ) by 16%, and 12-hour blood concentration (C 12hr ) by 26% in healthy adult subjects when tacrolimus (2 doses of 0.1 mg/kg 12 hours apart) was administered on the 10th day of CANCIDAS 70 mg daily, as compared to results from a control period in which tacrolimus was administered alone [see Drug Interactions (7.2) ] . The mechanism of interaction has not been confirmed. Figure 1 Figure 2
