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 ASTAGRAF XL (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 ASTAGRAF XL (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 ASTAGRAF XL and tacrolimus immediate-release treatment groups, respectively, through 12 months of treatment. The most common adverse reactions leading to discontinuation in ASTAGRAF XL-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 ASTAGRAF XL or tacrolimus immediate-release product in Study 1 are shown in Table 2 . Table 2: Percentage of Patients with Infections in Study 1 a Through One Year Post-Kidney Transplant a Study 1 was not designed to support comparative claims of ASTAGRAF XL compared to tacrolimus immediate-release product for the adverse reactions reported in this table.

Two kidney transplant patients on Prograf discontinued the study (withdrawn consent, sapovirus enteritis). Thirteen (13) pediatric kidney transplant patients completed 52 weeks on ASTAGRAF XL. The most common adverse reactions were diarrhea [7/13 (54%)], increased blood creatinine [6/13 (46%)], hypertension [3/13 (23%)], cough [4/13 (31%)], and upper respiratory tract infection [4/13 (31%)]. Stable Pediatric Transplant Patients Another study was conducted in 81 stable pediatric allograft recipients (including 48 kidney transplant patients) 5 to 16 years of age converted 1:1 (mg:mg) from Prograf to ASTAGRAF XL. Seventy-six (76) pediatric patients completed at least one year of ASTAGRAF XL-based treatment. Treatment-related adverse reactions were reported in 35%, including 13% serious adverse reactions. The most frequent adverse reactions by system organ class were infections (55.7%), followed by gastrointestinal disorders (27.8%), skin and subcutaneous tissue disorders (21.5%), respiratory, thoracic and mediastinal disorders (20.3% each). The most common adverse reactions were diarrhea (13.9%), headache (13.9%) and cough (11.4%). 6.2 Postmarketing Experience The following adverse reactions have been reported from marketing experience with tacrolimus in the U.S. and outside the U.S. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions have been chosen for inclusion due to either their seriousness, frequency of reporting or causal connection to ASTAGRAF XL: • Blood and Lymphatic System Disorders: Agranulocytosis, disseminated intravascular coagulation, hemolytic uremic syndrome, febrile neutropenia, pancytopenia, pure red cell aplasia [see Warnings and Precautions ( 5.13 )] , coagulopathy, thrombotic thrombocytopenic purpura, prolonged activated partial thromboplastin time, decreased blood fibrinogen • Cardiac Disorders: Cardiac arrest, myocardial infarction, ventricular fibrillation, congestive cardiac failure, hypertrophic cardiomyopathy, pericardial effusion, angina pectoris, supraventricular extrasystoles, supraventricular tachycardia, bradycardia, Torsades de pointes , QT prolongation • Ear Disorders: Hearing loss • Eye Disorders: Blindness, optic neuropathy, optic atrophy, photophobia • Gastrointestinal Disorders: Gastrointestinal hemorrhage, gastrointestinal perforation, pancreatitis, peritonitis, stomach ulcer, intestinal obstruction, ascites, colitis, ileus, impaired gastric emptying, dysphagia • Hepatobiliary Disorders: Hepatic failure, hepatic necrosis, cirrhosis, cholangitis, venoocclusive liver disease, bile duct stenosis, hepatic steatosis, jaundice • Hypersensitivity Reactions: Hypersensitivity, Stevens-Johnson syndrome, toxic epidermal necrolysis, urticaria • Immune System Disorders: Graft versus host disease (acute and chronic) • Investigations: Increased international normalized ratio • Metabolism and Nutrition Disorders: Hypoproteinemia • Musculoskeletal and Connective Tissue Disorders: Rhabdomyolysis, myalgia, polyarthritis, pain in extremity including Calcineurin-Inhibitor Induced Pain Syndrome (CIPS) • Neoplasms: Lymphoma including EBV-associated lymphoproliferative disorder, hepatosplenic T-cell lymphoma, PTLD [see Warnings and Precautions ( 5.1 )] , leukemia, melanoma • Nervous System Disorders: Cerebral infarction, progressive multifocal leukoencephalopathy (PML) sometimes fatal [see Warnings and Precautions ( 5.2 )] , posterior reversible encephalopathy syndrome (PRES) [see Warnings and Precautions ( 5.7 )] , coma, status epilepticus, quadriplegia, flaccid paralysis, hemiparesis, aphasia, syncope, carpal tunnel syndrome, nerve compression, mutism, dysarthria, somnolence • Psychiatric Disorders: Mental status changes • Renal and Urinary Disorders: Hemorrhagic cystitis, hematuria, urinary retention, urinary incontinence • Respiratory, Thoracic and Mediastinal Disorders: Interstitial lung disease, pulmonary hypertension, lung infiltration, rhinitis allergic, hiccups • Skin and Subcutaneous Tissue Disorders: Hyperpigmentation, photosensitivity • Vascular Disorders: Hemorrhage

11 DESCRIPTION Tacrolimus is the active ingredient in ASTAGRAF XL. Tacrolimus is a calcineurin-inhibitor immunosuppressant produced by Streptomyces tsukubaensis . Chemically, tacrolimus is designated as [3 S – [3 R *[ E (1 S *, 3 S *, 4 S *)], 4 S *, 5 R *, 8 S *, 9 E , 12 R *, 14 R *, 15 S *, 16 R *, 18 S *, 19 S *, 26a R *]] – 5, 6, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 24, 25, 26, 26a – hexadecahydro – 5, 19 – dihydroxy – 3 – [2 – (4 – hydroxy – 3 – methoxycyclo – hexyl) – 1 – methylethenyl] – 14, 16 – dimethoxy – 4, 10, 12, 18 – tetramethyl – 8 – (2 – propenyl) – 15, 19 – epoxy – 3H – pyrido[2, 1 – c ][1, 4]oxaazacyclotricosine – 1, 7, 20, 21(4H, 23H) – tetrone, monohydrate. The chemical structure of tacrolimus is: Tacrolimus has an empirical formula of C 44 H 69 NO 12 •H 2 O and a formula weight of 822.03. Tacrolimus appears as white crystals or crystalline powder. It is practically insoluble in water, freely soluble in ethanol, and very soluble in methanol and chloroform. ASTAGRAF XL is available for oral administration as hard gelatin capsules (tacrolimus extended-release capsules) containing the equivalent of 0.5 mg, 1 mg or 5 mg of anhydrous tacrolimus, USP. Inactive ingredients include ethylcellulose NF, hypromellose USP, magnesium stearate NF and lactose monohydrate NF. The ingredients are directly proportional across all capsule strengths. The capsule shell contains gelatin NF, titanium dioxide USP, ferric oxide NF, and sodium lauryl sulfate. Tacrolimus structural formula

MMF = Mycophenolate mofetil Recommended ASTAGRAF XL Initial Dosage Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant • Month 1: 7‑15 ng/mL • Months 2-6: 5‑15 ng/mL • > 6 Months: 5‑10 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: 10‑15 ng/mL • Months 2-6: 5‑15 ng/mL • > 6 Months: 5‑10 ng/mL PEDIATRIC With basiliximab, MMF and steroids 0.3 mg/kg once daily, administered within 24 hours following reperfusion • Month 1: 10‑20 ng/mL • > Month 1: 5‑15 ng/mL 2.1 Important Administration Instructions • ASTAGRAF XL should not be used without the supervision by a physician with experience in immunosuppressive therapy. • ASTAGRAF XL (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 ASTAGRAF XL capsules whole with liquid; patients must not chew, divide, or crush the capsules. • ASTAGRAF XL 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 ASTAGRAF XL [see Drug Interactions ( 7.2 )]. • Therapeutic drug monitoring is recommended for all patients receiving ASTAGRAF XL [see Dosage and Administration ( 2.4 )]. 2.2 Dosage Recommendations for Kidney Transplant Patients Table 1 includes the recommended starting ASTAGRAF XL 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 ASTAGRAF XL 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 ASTAGRAF XL MMF = mycophenolate mofetil Recommended ASTAGRAF XL Initial Dosage * Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant • Month 1: 7-15 ng/mL • Months 2-6: 5-15 ng/mL • > 6 Months: 5-10 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: 10-15 ng/mL • Months 2-6: 5-15 ng/mL • > 6 Months: 5-10 ng/mL PEDIATRIC With basiliximab, MMF and steroids 0.3 mg/kg once daily, administered within 24 hours following reperfusion. • Month 1: 10-20 ng/mL • > Month 1: 5-15 ng/mL 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 ASTAGRAF XL 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 ASTAGRAF XL, due to the reduced clearance and prolonged half-life [see Clinical Pharmacology ( 12.3 )]. Dose adjustments of ASTAGRAF XL 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 ASTAGRAF XL 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.

1 INDICATIONS AND USAGE ASTAGRAF XL ® is indicated for the prophylaxis of organ rejection in kidney transplant patients in combination with other immunosuppressants in adult and pediatric patients who can swallow capsules intact [see Use in Specific Populations ( 8.4 ) and Clinical Studies ( 14.1 ), ( 14.2 )]. ASTAGRAF XL is a calcineurin-inhibitor immunosuppressant indicated for the prophylaxis of organ rejection in kidney transplant patients in combination with other immunosuppressants in adult and pediatric patients who can swallow capsules intact. ( 1 , 8.4 , 14.1 , 14.2 )

10 OVERDOSAGE Postmarketing cases of overdose with tacrolimus have been reported. Overdosage adverse reactions included: • nervous system disorders (tremor, headache, confusional state, balance disorders, encephalopathy, lethargy and somnolence) • gastrointestinal disturbances (nausea, vomiting, and diarrhea) • abnormal renal function (increased blood urea nitrogen and elevated serum creatinine) • urticaria • hypertension • peripheral edema, and • infections [one fatal postmarketing case of bilateral pneumopathy and CMV infection was attributed to tacrolimus (extended-release) overdose]. Based on the poor aqueous solubility and extensive erythrocyte and plasma protein binding, it is anticipated that tacrolimus is not dialyzable to any significant extent; there is no experience with charcoal hemoperfusion. The oral use of activated charcoal has been reported in treating acute overdoses, but experience has not been sufficient to warrant recommending its use. General supportive measures and treatment of specific symptoms should be followed in all cases of overdosage.

7 DRUG INTERACTIONS • Risk of rejection with strong CYP3A inducers and risk of serious adverse reactions with strong CYP3A inhibitors: Adjust dose and monitor tacrolimus concentrations. ( 2.4 , 5.10 , 7.2 ) • Therapeutic drug monitoring and dose reduction for ASTAGRAF XL should be considered when ASTAGRAF XL is co-administered with cannabidiol ( 2.4 , 5.15 , 7.3 ). • See Full Prescribing Information for clinically significant drug interactions. ( 7.1 , 7.2 , 7.3 ) 7.1 Mycophenolic Acid When ASTAGRAF XL is prescribed with a given dose of a mycophenolic acid (MPA) product, exposure to MPA is higher with ASTAGRAF XL co-administration than with cyclosporine co-administration with MPA, because cyclosporine interrupts the enterohepatic recirculation of MPA while tacrolimus does not. Monitor for MPA-associated adverse reactions and reduce the dose of concomitantly administered mycophenolic acid products as needed. 7.2 Effects of Other Drugs on ASTAGRAF XL Table 5 displays the effects of other drugs on ASTAGRAF XL. Table 5: Effects of Other Drugs/Substances on ASTAGRAF XL a Drug/Substance Class or Name Drug Interaction Effect Recommendations a ASTAGRAF XL dosage adjustment recommendation based on observed effect of co-administered drug on tacrolimus exposures [see Clinical Pharmacology ( 12.3 )] , literature reports of altered tacrolimus exposures, or the other drug’s known CYP3A inhibitor/inducer status. b High dose or double strength grapefruit juice is a strong CYP3A inhibitor; low dose or single strength grapefruit juice is a moderate CYP3A inhibitor. c Strong CYP3A inhibitor/inducer, based on reported effect on exposures to tacrolimus along with supporting in vitro CYP3A inhibitor/inducer data, or based on drug-drug interaction studies with midazolam (sensitive CYP3A probe substrate). Grapefruit or grapefruit juice b May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )]. Avoid grapefruit or grapefruit juice. Alcohol May increase the rate of tacrolimus release and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )]. Avoid alcoholic beverages. Strong CYP3A Inducers c : Antimycobacterials (e.g., rifampin, rifabutin), anticonvulsants (e.g., phenytoin, carbamazepine and phenobarbital), St John’s wort May decrease tacrolimus whole blood trough concentrations and increase the risk of rejection [see Warnings and Precautions ( 5.10 )]. Increase ASTAGRAF XL dose and monitor tacrolimus whole blood trough concentrations [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )]. Strong CYP3A Inhibitors c : Protease inhibitors (e.g., nelfinavir, telaprevir, boceprevir, ritonavir), azole antifungals (e.g., voriconazole, posaconazole, itraconazole, ketoconazole), antibiotics (e.g., clarithromycin, troleandomycin, chloramphenicol), nefazodone, letermovir, Schisandra sphenanthera extracts May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation). A rapid, sharp rise in tacrolimus levels may occur early, despite an immediate reduction of tacrolimus dose [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )]. Reduce ASTAGRAF XL dose (for voriconazole and posaconazole, give one-third of the original dose) and adjust dose based on tacrolimus whole blood trough concentrations [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )]. Early and frequent monitoring of tacrolimus whole blood trough levels should start within 1-3 days and continue monitoring as necessary [see Warnings and Precautions ( 5.10 )] . Mild or Moderate CYP3A Inhibitors: Clotrimazole, antibiotics (e.g., verapamil, diltiazem, nifedipine, nicardipine), amiodarone, danazol, ethinyl estradiol, cimetidine, lansoprazole and omeprazole May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )]. Monitor tacrolimus whole blood trough concentrations and reduce ASTAGRAF XL dose if needed [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )]. Other drugs, such as: Magnesium and aluminum hydroxide antacids Metoclopramide May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )]. Monitor tacrolimus whole blood trough concentrations and reduce ASTAGRAF XL dose if needed [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )]. Mild or Moderate CYP3A Inducers Methylprednisolone, prednisone May decrease tacrolimus whole blood trough concentrations. Monitor tacrolimus whole blood trough concentrations and adjust ASTAGRAF XL dose if needed [see Dosage and Administration ( 2.3 , 2.4 )]. Caspofungin May decrease tacrolimus whole blood trough concentrations. Monitor tacrolimus whole blood trough concentrations and adjust ASTAGRAF XL dose if needed [see Dosage and Administration ( 2.3 , 2.4 )]. Direct Acting Antiviral (DAA) Therapy The pharmacokinetics of tacrolimus may be impacted by changes in liver function during DAA therapy, related to clearance of HCV virus. Close monitoring and potential dose adjustment of ASTAGRAF XL is warranted to ensure continued efficacy and safety [see Dosage and Administration ( 2.3 , 2.4 )] . 7.3 Cannabidiol The blood levels of tacrolimus may increase upon concomitant use with cannabidiol. When cannabidiol and ASTAGRAF XL are co-administered, closely monitor for an increase in tacrolimus blood levels and for adverse reactions suggestive of tacrolimus toxicity. A dose reduction of ASTAGRAF XL should be considered as needed when ASTAGRAF XL is co-administered with cannabidiol [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.15 )] .

12 CLINICAL PHARMACOLOGY 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). 12.3 Pharmacokinetics Table 7 summarizes the pharmacokinetic (PK) parameters of tacrolimus following oral administration of ASTAGRAF XL in healthy subjects and in kidney transplant patients. Whole blood tacrolimus concentrations in these PK studies were measured using validated HPLC/MS/MS assays.

By Day 3 post-transplant, the AUC 24 was similar between the two formulations. On Day 14 (steady state), the AUC 24 for ASTAGRAF XL 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 ASTAGRAF XL 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 ASTAGRAF XL 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 ASTAGRAF XL was administered 1.5 hours after consumption of a high-fat breakfast, tacrolimus exposure was decreased approximately 35%. Administration of ASTAGRAF XL 1 hour prior to a high-fat breakfast reduced tacrolimus exposure by 10%. ASTAGRAF XL 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 ASTAGRAF XL reduced AUC inf by 35% relative to morning dosing. ASTAGRAF XL 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 5-50 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 ASTAGRAF XL daily for 10 days was 38 ± 3 hours in 24 healthy subjects. Specific Populations Pediatric Patients De Novo Pediatric Transplant Patients A PK study to compare ASTAGRAF XL to Prograf capsules was conducted in 44 de novo pediatric transplant patients, including 25 pediatric de novo kidney transplant patients, 4 to 15 years of age (mean age of 10.6 years). These patients were administered a starting daily dose of 0.3 mg/kg/day of Prograf capsules divided into two daily doses or ASTAGRAF XL once daily. Overall, the tacrolimus PK parameters AUC 24 and C 24 are comparable among Prograf and ASTAGRAF XL on Days 7 and 28 ( Table 8 ).

Pediatric kidney transplant patients who had been administered Prograf for at least 3 months prior to treatment were converted on a 1:1 (mg:mg) basis from Prograf, given in two divided doses, to ASTAGRAF XL once-daily. Overall, the tacrolimus AUC 24 , C max , and C 24 are comparable upon conversion from Prograf to ASTAGRAF XL on a 1:1 (mg:mg) basis in stable pediatric kidney transplant patients ( Table 9 ).

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 12.0 ± 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: > 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 ASTAGRAF XL 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 )] . Figures 1 and 2 summarize the PK data from drug interaction studies of ASTAGRAF XL 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 ASTAGRAF XL) 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.

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).

12.3 Pharmacokinetics Table 7 summarizes the pharmacokinetic (PK) parameters of tacrolimus following oral administration of ASTAGRAF XL in healthy subjects and in kidney transplant patients. Whole blood tacrolimus concentrations in these PK studies were measured using validated HPLC/MS/MS assays.

By Day 3 post-transplant, the AUC 24 was similar between the two formulations. On Day 14 (steady state), the AUC 24 for ASTAGRAF XL 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 ASTAGRAF XL 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 ASTAGRAF XL 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 ASTAGRAF XL was administered 1.5 hours after consumption of a high-fat breakfast, tacrolimus exposure was decreased approximately 35%. Administration of ASTAGRAF XL 1 hour prior to a high-fat breakfast reduced tacrolimus exposure by 10%. ASTAGRAF XL 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 ASTAGRAF XL reduced AUC inf by 35% relative to morning dosing. ASTAGRAF XL capsules should be taken consistently at the same time every morning.

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 ASTAGRAF XL daily for 10 days was 38 ± 3 hours in 24 healthy subjects. Specific Populations Pediatric Patients De Novo Pediatric Transplant Patients A PK study to compare ASTAGRAF XL to Prograf capsules was conducted in 44 de novo pediatric transplant patients, including 25 pediatric de novo kidney transplant patients, 4 to 15 years of age (mean age of 10.6 years).

Overall, the tacrolimus PK parameters AUC 24 and C 24 are comparable among Prograf and ASTAGRAF XL on Days 7 and 28 ( Table 8 ).

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 12.0 ± 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: > 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 ASTAGRAF XL 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 )] . Figures 1 and 2 summarize the PK data from drug interaction studies of ASTAGRAF XL 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 ASTAGRAF XL) 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.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Carcinogenicity studies were conducted in male and female rats and mice. In the 80-week mouse oral study and in the 104-week rat oral study, no relationship of tumor incidence to tacrolimus dosage was found. The highest dose used in the mouse was 3 mg/kg/day (0.49 times the AUC at the maximum clinical dose of 0.2 mg/kg/day) and in the rat was 5 mg/kg/day (0.14 times the AUC at the maximum clinical dose of 0.2 mg/kg/day) [see Warnings and Precautions ( 5.1 )] . A 104-week dermal carcinogenicity study was performed in mice with tacrolimus ointment (0.03%-3%), equivalent to tacrolimus doses of 1.1-118 mg/kg/day or 3.3-354 mg/m 2 /day. In the study, the incidence of skin tumors was minimal and the topical application of tacrolimus was not associated with skin tumor formation under ambient room lighting. However, a statistically significant elevation in the incidence of pleomorphic lymphoma in high-dose male (25/50) and female animals (27/50), and in the incidence of undifferentiated lymphoma in high-dose female animals (13/50), was noted in the mouse dermal carcinogenicity study. Lymphomas were noted in the mouse dermal carcinogenicity study at a daily dose of 3.5 mg/kg (0.1% tacrolimus ointment; 2.4-fold the human exposure in stable adult kidney transplant patients > 6 months post-transplant). No drug-related tumors were noted in the mouse dermal carcinogenicity study at a daily dose of 1.1 mg/kg (0.03% tacrolimus ointment). The relevance of topical administration of tacrolimus in the setting of systemic tacrolimus use is unknown. The implications of these carcinogenicity studies are limited; doses of tacrolimus were administered that likely induced immunosuppression in these animals, impairing their immune system’s ability to inhibit unrelated carcinogenesis. Mutagenesis No evidence of genotoxicity was seen in bacterial ( Salmonella and E. coli ) or mammalian (Chinese hamster lung-derived cells) in vitro assays of mutagenicity, the in vitro CHO/HGPRT assay of mutagenicity, or in vivo clastogenicity assays performed in mice; tacrolimus did not cause unscheduled DNA synthesis in rodent hepatocytes. Impairment of Fertility Tacrolimus subcutaneously administered to male rats at paternally toxic doses of 2 mg/kg/day [1.6 times the maximum recommended clinical dose (0.2 mg/kg/day) on a mg/m 2 basis] or 3 mg/kg/day (2.4 times the maximum recommended clinical dose) resulted in a dose-related decrease in sperm count. Tacrolimus administered orally at 1.0 mg/kg (0.8 times the maximum clinical dose) to male and female rats, prior to and during mating, as well as to dams during gestation and lactation, was associated with embryolethality and adverse effects on female reproduction. Effects on female reproductive function (parturition) and embryolethal effects were indicated by a higher rate of pre- and post-implantation loss and increased numbers of undelivered and nonviable pups. When administered at 3.2 mg/kg (2.6 times the maximum clinical dose range based on body surface area), tacrolimus was associated with maternal and paternal toxicity as well as reproductive toxicity including marked adverse effects on estrus cycles, parturition, pup viability, and pup malformations.

14 CLINICAL STUDIES 14.1 ASTAGRAF XL with Basiliximab Induction Study 1 was a 12-month, randomized, open-label trial of ASTAGRAF XL (N=214) compared to active-control of tacrolimus (Prograf) immediate-release (N=212), conducted primarily in the U.S. in patients who were a recipient of a primary or retransplanted non-HLA-identical living or deceased donor kidney transplant. All patients received basiliximab induction and concomitant mycophenolate mofetil (MMF) and corticosteroids. The study population was 17 to 77 years of age, the mean age was 48 years; 64% were male and 36% were female; 73% were Caucasian, 22% were African-American, 2% were Asian, and 3% were categorized as other races. Living donors provided 49% of the organs and 51% of patients received a kidney transplant from a deceased donor with a mean cold ischemia time of 19 hours. The most frequent diseases leading to transplantation were balanced between the groups and included nephrosclerosis/hypertensive nephropathy, diabetic nephropathy, glomerulonephritis, and polycystic kidney disease. In the study, 97% of patients had no previous transplant and 3% had a previous transplant. Study Medications ASTAGRAF XL or Control [Prograf (tacrolimus) capsules] The initial dose of ASTAGRAF XL was administered prior to reperfusion or within 48 hours after completion of the transplant procedure. The protocol-defined initial post-operative daily doses were 0.15 to 0.20 mg per kg given as a single dose in the morning for ASTAGRAF XL and 0.075 to 0.10 mg per kg twice daily for control. The ASTAGRAF XL and control dosage was then adjusted on the basis of safety and efficacy and a target whole blood tacrolimus trough concentration range of 7 to 16 ng/mL for the first 90 days post-transplant and 5 to 15 ng/mL thereafter. The average recorded starting tacrolimus daily dose, given any time up to day 2 post-transplant, was higher for ASTAGRAF XL than for control (0.14 mg per kg per day versus 0.10 mg per kg per day). Thereafter, to achieve comparable mean tacrolimus trough concentrations, on average 15% higher total mean daily doses of tacrolimus were required for ASTAGRAF XL than for control. Tacrolimus whole blood trough concentrations were monitored on Days 3, 7, 10, 14, and 21, then Months 1, 2, 4, 6, 8, 10, and 12. Table 10 shows the tacrolimus whole blood trough concentrations measured at protocol-specified time points for ASTAGRAF XL. Approximately 80% of ASTAGRAF XL-treated patients maintained tacrolimus whole trough blood concentrations between 5 to 17 ng/mL during months 1 through 2 and between 4 to 12 ng/mL from months 3 through 12. Table 10: Observed Tacrolimus Whole Blood Trough Concentrations in ASTAGRAF XL-Treated Kidney Transplant Patients in Study 1 Scheduled Visit Tacrolimus Whole Blood Trough Concentrations (ng/mL) Immunoassay was used in most laboratories.

Subsequent MMF was administered orally 1 gram twice daily or up to 1.5 grams twice daily in African-American patients. Dose-equivalent three times daily or four times daily dosing was permitted if MMF tolerability was a concern. The MMF dosages administered by time period in ASTAGRAF XL-treated patients are shown in Table 12 . The MMF dosage was reduced to less than 2 grams per day by month 12 in 56% of ASTAGRAF XL-treated patients. Approximately 57% of the MMF dose reductions were because of adverse reactions in the ASTAGRAF XL group [see Adverse Reactions ( 6.1 )] .

Efficacy Results The efficacy failure rate, defined as the percentage of patients with biopsy-proven acute rejection (BPAR), graft failure, death, and/or lost to follow at 12 months, is shown in Table 13 for the intent-to-treat population, as well as the rates of the individual events.

This trial was designed to remain double-blind until the last patient enrolled had completed 24 weeks on study treatment. Patients with a high immunologic risk defined as a panel reactive antibody (PRA) grade > 50% in the previous 6 months and/or with a previous graft survival of less than 12 months due to immunologic reasons were excluded, as were patients of donor kidneys with cold ischemia time > 30 hours, or donor kidneys from a non heart-beating donor. The patient treatment assignments remained blinded for 12 months for 96% of the patients participating in the trial. All patients received concomitant MMF and corticosteroids without induction. The population was 18 to 65 years of age; the mean age was 48 years; 63% of the study population was male; 82% were Caucasian, 5% were African-American, 2% were Asian, and 11% were categorized as other races. Living donors provided 27% of the organs and 73% of patients received a kidney transplant from a deceased donor with a mean cold ischemia time of 17 hours. The most frequent diseases leading to transplantation were balanced between the groups and included nephrosclerosis/hypertensive nephropathy, diabetic nephropathy, glomerulonephritis, and polycystic kidney disease. Study Medication ASTAGRAF XL or Control [Prograf (tacrolimus) capsules] The protocol-specified initial preoperative dose for both ASTAGRAF XL and control was 0.1 mg per kg given orally in one dose within 12 hours prior to reperfusion, given at any time of the day. The initial post-operative tacrolimus daily dose (0.2 mg per kg per day) was given orally in one dose, preferably in the morning for ASTAGRAF XL, and was given as 0.1 mg/kg twice daily for control. Subsequent doses of ASTAGRAF XL and control were adjusted on the basis of clinical evidence of efficacy, occurrence of adverse events and according to whole blood tacrolimus trough concentration target ranges of 10 to 15 ng/mL for the first 28 days post-transplant, 5 to 15 ng/mL from Day 29 to Day 168, 5 to 10 ng/mL thereafter. The actual tacrolimus doses on day 0 (0.1 mg per kg per day preoperative) and day 1 (0.2 mg per kg per day post-operative) were comparable between ASTAGRAF XL and control. Thereafter, to achieve comparable mean tacrolimus trough concentrations, on average, 25% higher total mean daily doses of tacrolimus were required for ASTAGRAF XL than for control. Tacrolimus whole blood trough concentrations were monitored on Days 1, 3, 7, 14, then Months 1, 2, 3, 6, 11, 12, and then every 3 months. Table 15 shows the tacrolimus whole blood trough concentrations measured at protocol-specified time points for ASTAGRAF XL. Approximately 80% of ASTAGRAF XL-treated patients maintained tacrolimus whole trough blood concentrations between 6 to 20 ng/mL during months 1 through 2, and between 6 to 14 ng/mL from months 3 through 12.

8.5 Geriatric Use Clinical studies of ASTAGRAF XL did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In Studies 1 and 2, 29 patients were 65 years of age and older, and 3 patients were 75 years of age and over [see Clinical Studies ( 14 )] . Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

8.4 Pediatric Use The safety and effectiveness of ASTAGRAF XL in de novo pediatric kidney transplant patients have been established. Use of ASTAGRAF XL in pediatric kidney transplant patients is based on adequate and well-controlled studies of ASTAGRAF XL in adult kidney transplant patients [see Clinical Studies ( 14.1 , 14.2 )] and supported by pharmacokinetic and safety data of ASTAGRAF XL in pediatric transplant patients 4 years of age and older who are able to swallow capsules intact and Prograf (tacrolimus) capsules in adult and pediatric transplant patients [see Clinical Pharmacology ( 12.3 )]. De Novo Pediatric Kidney Transplant Patients A pharmacokinetic and safety study included 25 de novo pediatric kidney transplant patients, 4 to 15 years of age, randomized to Prograf (N=12) or ASTAGRAF XL (N=13). Tacrolimus exposures for the two drug products were comparable on Days 7 and 28 [see Clinical Pharmacology ( 12.3 )]. Among the 13 pediatric kidney transplant patients who completed 52 weeks on ASTAGRAF XL, there were no graft loss, deaths or episodes of biopsy-proven acute rejection [see Dosage and Administration ( 2.2 ) and Adverse Reactions ( 6.1 )]. Stable Pediatric Kidney Transplant Patients Another pharmacokinetic and safety study included 48 stable pediatric kidney transplant patients, 5 to 16 years of age, who were converted from a Prograf-based regimen to ASTAGRAF XL. Tacrolimus systemic exposures for the two drug products were comparable [see Clinical Pharmacology ( 12.3 )]. Acute rejections were reported in 2/48 kidney pediatric patients that responded to subsequent treatment. There were no graft failures or deaths following use of ASTAGRAF XL during the 54-week follow up [see Adverse Reactions ( 6.1 )].

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy registry that monitors pregnancy outcomes in women exposed to ASTAGRAF XL during pregnancy. The Transplantation Pregnancy Registry International (TPRI) is a voluntary pregnancy exposure registry that monitors outcomes of pregnancy in female transplant recipients and those fathered by male transplant recipients exposed to immunosuppressants including tacrolimus. Healthcare providers are encouraged to advise their patients to register by contacting the Transplantation Pregnancy Registry International at 1-877-955-6877 or https://www.transplantpregnancyregistry.org/ . Risk Summary Tacrolimus can cause fetal harm when administered to a pregnant woman. Data from postmarketing surveillance and TPRI suggest that infants exposed to tacrolimus in utero are at a risk of prematurity, birth defects/congenital anomalies, low birth weight, and fetal distress [see Human Data]. Advise pregnant women of the potential risk to the fetus. Administration of oral tacrolimus to pregnant rabbits and rats throughout the period of organogenesis was associated with maternal toxicity/lethality, and an increased incidence of abortion, malformation and embryofetal death at clinically relevant doses [0.5 the maximum recommended clinical dose (0.2 mg/kg/day), on a mg/m 2 basis]. Administration of oral tacrolimus to pregnant rats after organogenesis and throughout lactation produced maternal toxicity, effects on parturition, reduced pup viability and reduced pup weight at clinically relevant doses (0.8 the maximum recommended clinical dose, on a mg/m 2 basis). Administration of oral tacrolimus to rats prior to mating, and throughout gestation and lactation produced maternal toxicity/lethality, marked effects on parturition, embryofetal loss, malformations, and reduced pup viability at clinically relevant doses (0.8 times the maximum recommended clinical dose, on a mg/m 2 basis). Interventricular septal defects, hydronephrosis, craniofacial malformations and skeletal effects were observed in offspring that died [see Animal Data]. The background risk of major birth defects and miscarriage in the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Risks during pregnancy are increased in organ transplant recipients. The risk of premature delivery following transplantation is increased. Pre-existing hypertension and diabetes confer additional risk to the pregnancy of an organ transplant recipient. Pre-gestational and gestational diabetes are associated with birth defects/congenital anomalies, hypertension, low birth weight and fetal death. Cholestasis of pregnancy (COP) was reported in 7% of liver or liver-kidney (LK) transplant recipients, compared with approximately 1% of pregnancies in the general population. However, COP symptoms resolved postpartum and no long-term effects on the offspring were reported. Maternal Adverse Reactions ASTAGRAF XL may increase hyperglycemia in pregnant women with diabetes (including gestational diabetes). Monitor maternal blood glucose levels regularly [see Warnings and Precautions ( 5.5 )] . ASTAGRAF XL may exacerbate hypertension in pregnant women and increase pre-eclampsia. Monitor and control blood pressure [see Warnings and Precautions ( 5.8 , 5.9 )] . Fetal/Neonatal Adverse Reactions Renal dysfunction, transient neonatal hyperkalemia and low birth weight have been reported at the time of delivery in infants of mothers taking ASTAGRAF XL. Labor or Delivery There is an increased risk for premature delivery (< 37 weeks) following transplantation and maternal exposure to ASTAGRAF XL. Data Human Data There are no adequate and well-controlled studies on the effects of tacrolimus in human pregnancy. Safety data from the TPRI and postmarketing surveillance suggest infants exposed to tacrolimus in utero have an increased risk for miscarriage, pre-term delivery (< 37 weeks), low birth weight (< 2500 g), birth defects/congenital anomalies and fetal distress. TPRI reported 450 and 241 total pregnancies in kidney and liver transplant recipients exposed to tacrolimus, respectively. The TPRI pregnancy outcomes are summarized in Table 6 . In the table below, the number of recipients exposed to tacrolimus concomitantly with mycophenolic acid (MPA) products during the preconception and first trimester periods is high (27% and 29% for kidney and liver transplant recipients, respectively). Because MPA products may also cause birth defects, the birth defect rate may be confounded and this should be taken into consideration when reviewing the data, particularly for birth defects. Birth defects observed include cardiac malformations, craniofacial malformations, renal/urogenital disorders, skeletal abnormalities, neurological abnormalities and multiple malformations. Table 6: TPRI-Reported Pregnancy Outcomes in Transplant Recipients with Exposure to Tacrolimus Kidney Liver Pregnancy Outcomes Includes multiple births and terminations. 462 253 Miscarriage 24.5% 25% Live births 331 180 Pre-term delivery (< 37 weeks) 49% 42% Low birth weight (< 2500 g) 42% 30% Birth defects 8% Birth defect rate confounded by concomitant MPA products exposure in over half of offspring with birth defects. 5% Additional information reported by TPRI in pregnant transplant patients receiving tacrolimus included diabetes during pregnancy in 9% of kidney recipients and 13% of liver recipients and hypertension during pregnancy in 53% of kidney recipients and 16.2% of liver recipients. Animal Data Administration of oral tacrolimus to pregnant rabbits throughout organogenesis produced maternal toxicity and abortion at 0.32 mg/kg (0.5 times the maximum recommended clinical dose [0.2 mg/kg/day], on a mg/m 2 basis). At 1 mg/kg (1.6 times the maximum recommended clinical dose), embryofetal lethality and fetal malformations (ventricular hypoplasia, interventricular septal defect, bulbous aortic arch, stenosis of ductus arteriosus, omphalocele, gallbladder agenesis, skeletal anomalies) were observed. Administration of 3.2 mg/kg oral tacrolimus (2.6 times the maximum recommended clinical dose) to pregnant rats throughout organogenesis produced maternal toxicity/lethality, embryofetal lethality and decreased fetal body weight in the offspring of C-sectioned dams; and decreased pup viability and interventricular septal defect in offspring of dams that delivered. In a peri-/postnatal development study, oral administration of tacrolimus to pregnant rats during late gestation (after organogenesis) and throughout lactation produced maternal toxicity, effects on parturition, and reduced pup viability at 3.2 mg/kg (2.6 times the maximum recommended clinical dose); among these pups that died early, an increased incidence of kidney hydronephrosis was observed. Reduced pup weight was observed at 1.0 mg/kg (0.8 times the maximum recommended clinical dose). Administration of oral tacrolimus to rats prior to mating, and throughout gestation and lactation produced maternal toxicity/lethality, embryofetal loss and reduced pup viability at 3.2 mg/kg (2.6 times the maximum recommended clinical dose range). Interventricular septal defects, hydronephrosis, craniofacial malformations and skeletal effects were observed in offspring that died. Effects on parturition (incomplete delivery of nonviable pups) were observed at 1 mg/kg (0.8 times the maximum recommended clinical dose) [see Nonclinical Toxicology ( 13.1 )].

Effects on parturition (incomplete delivery of nonviable pups) were observed at 1 mg/kg (0.8 times the maximum recommended clinical dose) [see Nonclinical Toxicology ( 13.1 )]. 8.2 Lactation Risk Summary Controlled lactation studies have not been conducted in humans; however, tacrolimus has been reported to be present in human milk. The effects of tacrolimus on the breastfed infant, or on milk production, have not been assessed. Tacrolimus is excreted in rat milk and in peri-/postnatal rat studies; exposure to tacrolimus during the postnatal period was associated with developmental toxicity in the offspring at clinically relevant doses [see Pregnancy ( 8.1 ) and Nonclinical Toxicology ( 13.1 )] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ASTAGRAF XL and any potential adverse effects on the breastfed child from ASTAGRAF XL or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Contraception ASTAGRAF XL can cause fetal harm when administered to pregnant women. Advise female and male patients of reproductive potential to speak to their healthcare provider on family planning options including appropriate contraception prior to starting treatment with ASTAGRAF XL [see Use in Specific Populations ( 8.1 ) and Nonclinical Toxicology ( 13.1 )] . Infertility Based on findings in animals, male and female fertility may be compromised by treatment with ASTAGRAF XL [see Nonclinical Toxicology ( 13.1 )]. 8.4 Pediatric Use The safety and effectiveness of ASTAGRAF XL in de novo pediatric kidney transplant patients have been established. Use of ASTAGRAF XL in pediatric kidney transplant patients is based on adequate and well-controlled studies of ASTAGRAF XL in adult kidney transplant patients [see Clinical Studies ( 14.1 , 14.2 )] and supported by pharmacokinetic and safety data of ASTAGRAF XL in pediatric transplant patients 4 years of age and older who are able to swallow capsules intact and Prograf (tacrolimus) capsules in adult and pediatric transplant patients [see Clinical Pharmacology ( 12.3 )]. De Novo Pediatric Kidney Transplant Patients A pharmacokinetic and safety study included 25 de novo pediatric kidney transplant patients, 4 to 15 years of age, randomized to Prograf (N=12) or ASTAGRAF XL (N=13). Tacrolimus exposures for the two drug products were comparable on Days 7 and 28 [see Clinical Pharmacology ( 12.3 )]. Among the 13 pediatric kidney transplant patients who completed 52 weeks on ASTAGRAF XL, there were no graft loss, deaths or episodes of biopsy-proven acute rejection [see Dosage and Administration ( 2.2 ) and Adverse Reactions ( 6.1 )]. Stable Pediatric Kidney Transplant Patients Another pharmacokinetic and safety study included 48 stable pediatric kidney transplant patients, 5 to 16 years of age, who were converted from a Prograf-based regimen to ASTAGRAF XL. Tacrolimus systemic exposures for the two drug products were comparable [see Clinical Pharmacology ( 12.3 )]. Acute rejections were reported in 2/48 kidney pediatric patients that responded to subsequent treatment. There were no graft failures or deaths following use of ASTAGRAF XL during the 54-week follow up [see Adverse Reactions ( 6.1 )]. 8.5 Geriatric Use Clinical studies of ASTAGRAF XL did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In Studies 1 and 2, 29 patients were 65 years of age and older, and 3 patients were 75 years of age and over [see Clinical Studies ( 14 )] . Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. 8.6 Renal Impairment The pharmacokinetics of tacrolimus in patients with renal impairment was similar to that in healthy subjects with normal renal function. However, due to its potential for nephrotoxicity, monitoring of renal function in patients with renal impairment is recommended; tacrolimus dosage should be reduced if indicated [see Warnings and Precautions ( 5.6 ) and Clinical Pharmacology ( 12.3 )] . 8.7 Hepatic Impairment The mean clearance of tacrolimus was substantially lower in patients with severe hepatic impairment (mean Child-Pugh score: > 10) compared to healthy subjects with normal hepatic function [see Clinical Pharmacology ( 12.3 )] . With greater tacrolimus whole blood trough concentrations in patients with severe hepatic impairment, there is a greater risk of adverse reactions and dosage reduction is recommended [see Dosage and Administration ( 2.3 )]. For patients with moderate hepatic impairment, monitor tacrolimus whole blood trough concentrations. For patients with mild hepatic impairment, no dosage adjustments are needed. 8.8 Race or Ethnicity African-American patients may need to be titrated to higher dosages to attain comparable trough concentrations compared to Caucasian patients [see Dosage and Administration ( 2.3 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14 )].
