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. ASTAGRAF XL, MMF, steroids, basiliximab induction N=214 Tacrolimus immediate-release product, MMF, steroids, basiliximab induction N=212 All Infections 69% 69% Respiratory Infections 34% 31% Urinary Tract Infections 16% 25% Cytomegalovirus Infections 10% 11% Bacterial Infections 8% 12% Gastroenteritis 7% 3% Polyomavirus Infections 3% 5% Serious Infections 22% 23% New Onset Diabetes After Transplant (NODAT) The incidence of new onset diabetes after transplantation (defined by the composite occurrence of ≥ 2 fasting plasma glucose values that were > 126 mg/dL at ≥ 30 days apart, insulin use for ≥ 30 consecutive days, oral hypoglycemic use for ≥ 30 consecutive days, and/or HbA 1C ≥ 6.5%) is summarized in Table 3 below for Study 1 through one year post-transplant [see Warnings and Precautions ( 5.5 )].

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 o …

8 USE IN SPECIFIC POPULATIONS Pregnancy: Can cause fetal harm. Advise pregnant women of the potential risk to the fetus. ( 8.1 , 8.3 ) 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 ( 10) compared to healthy subjects with normal hepatic function [see Clinical Pharmacology ( 12. …

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).

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

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.
