Neoral

INDICATIONS AND USAGE Kidney, Liver, and Heart Transplantation Neoral is indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants. Neoral has been used in combination with azathioprine and corticosteroids. Rheumatoid Arthritis Neoral is indicated for the treatment of patients with severe active, rheumatoid arthritis where the disease has not adequately responded to methotrexate. Neoral can be used in combination with methotrexate in rheumatoid arthritis patients who do not respond adequately to methotrexate alone. Psoriasis Neoral is indicated for the treatment of adult, nonimmunocompromised patients with severe (i.e., extensive and/or disabling), recalcitrant, plaque psoriasis who have failed to respond to at least one systemic therapy (e.g., PUVA, retinoids, or methotrexate) or in patients for whom other systemic therapies are contraindicated or cannot be tolerated. While rebound rarely occurs, most patients will experience relapse with Neoral as with other therapies upon cessation of treatment.

DOSAGE AND ADMINISTRATION Neoral Soft Gelatin Capsules (cyclosporine capsules, USP) MODIFIED and Neoral Oral Solution (cyclosporine oral solution, USP) MODIFIED Neoral has increased bioavailability in comparison to Sandimmune. Neoral and Sandimmune are not bioequivalent and cannot be used interchangeably without physician supervision. The daily dose of Neoral should always be given in two divided doses (BID). It is recommended that Neoral be administered on a consistent schedule with regard to time of day and relation to meals. Grapefruit and grapefruit juice affect metabolism, increasing blood concentration of cyclosporine, thus should be avoided. Specific Populations Renal Impairment in Kidney, Liver, and Heart Transplantation Cyclosporine undergoes minimal renal elimination and its pharmacokinetics do not appear to be significantly altered in patients with end-stage renal disease who receive routine hemodialysis treatments (see CLINICAL PHARMACOLOGY) . However, due to its nephrotoxic potential (see WARNINGS) , careful monitoring of renal function is recommended; cyclosporine dosage should be reduced if indicated (see WARNINGS and PRECAUTIONS) . Renal Impairment in Rheumatoid Arthritis and Psoriasis Patients with impaired renal function should not receive cyclosporine (see CONTRAINDICATIONS, WARNINGS and PRECAUTIONS) . Hepatic Impairment The clearance of cyclosporine may be significantly reduced in severe liver disease patients (see CLINICAL PHARMACOLOGY) . Dose reduction may be necessary in patients with severe liver impairment to maintain blood concentrations within the recommended target range (see WARNINGS and PRECAUTIONS) . Newly Transplanted Patients The initial oral dose of Neoral can be given 4 to 12 hours prior to transplantation or be given postoperatively. The initial dose of Neoral varies depending on the transplanted organ and the other immunosuppressive agents included in the immunosuppressive protocol. In newly transplanted patients, the initial oral dose of Neoral is the same as the initial oral dose of Sandimmune. Suggested initial doses are available from the results of a 1994 survey of the use of Sandimmune in US transplant centers. The mean ± SD initial doses were 9 ± 3 mg/kg/day for renal transplant patients (75 centers), 8 ± 4 mg/kg/day for liver transplant patients (30 centers), and 7 ± 3 mg/kg/day for heart transplant patients (24 centers). Total daily doses were divided into two equal daily doses. The Neoral dose is subsequently adjusted to achieve a pre-defined cyclosporine blood concentration (see Blood Concentration Monitoring in Transplant Patients , below). If cyclosporine trough blood concentrations are used, the target range is the same for Neoral as for Sandimmune. Using the same trough concentration target range for Neoral as for Sandimmune results in greater cyclosporine exposure when Neoral is administered (see Pharmacokinetics, Absorption) . Dosing should be titrated based on clinical assessments of rejection and tolerability. Lower Neoral doses may be sufficient as maintenance therapy. Adjunct therapy with adrenal corticosteroids is recommended initially. Different tapering dosage schedules of prednisone appear to achieve similar results. A representative dosage schedule based on the patient’s weight started with 2.0 mg/kg/day for the first 4 days tapered to 1.0 mg/kg/day by 1 week, 0.6 mg/kg/day by 2 weeks, 0.3 mg/kg/day by 1 month, and 0.15 mg/kg/day by 2 months and thereafter as a maintenance dose. Steroid doses may be further tapered on an individualized basis depending on status of patient and function of graft. Adjustments in dosage of prednisone must be made according to the clinical situation. Conversion from Sandimmune to Neoral in Transplant Patients In transplanted patients who are considered for conversion to Neoral from Sandimmune, Neoral should be started with the same daily dose as was previously used with Sandimmune (1:1 dose conversion). The Neoral dose should subsequent…

WARNINGS (See also BOXED WARNING.) All Patients Cyclosporine, the active ingredient of Neoral, can cause nephrotoxicity and hepatotoxicity. The risk increases with increasing doses of cyclosporine. Renal dysfunction, including structural kidney damage, is a potential consequence of Neoral and therefore renal function must be monitored during therapy. Care should be taken in using cyclosporine with nephrotoxic drugs (see PRECAUTIONS) . Patients receiving Neoral require frequent monitoring of serum creatinine (see Special Monitoring under DOSAGE AND ADMINISTRATION) . Elderly patients should be monitored with particular care, since decreases in renal function also occur with age. If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can be associated with the occurrence of structural kidney damage and persistent renal dysfunction. An increase in serum creatinine and BUN may occur during Neoral therapy and reflect a reduction in the glomerular filtration rate. Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated. The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced without dose reduction or discontinuation. Because Neoral is not bioequivalent to Sandimmune, conversion from Neoral to Sandimmune using a 1:1 ratio (mg/kg/day) may result in lower cyclosporine blood concentrations. Conversion from Neoral to Sandimmune should be made with increased monitoring to avoid the potential of underdosing. Kidney, Liver, and Heart Transplant Nephrotoxicity Cyclosporine, the active ingredient of Neoral, can cause nephrotoxicity and hepatotoxicity when used in high doses. It is not unusual for serum creatinine and BUN levels to be elevated during cyclosporine therapy. These elevations in renal transplant patients do not necessarily indicate rejection, and each patient must be fully evaluated before dosage adjustment is initiated. Based on the historical Sandimmune experience with oral solution, nephrotoxicity associated with cyclosporine had been noted in 25% of cases of renal transplantation, 38% of cases of cardiac transplantation, and 37% of cases of liver transplantation. Mild nephrotoxicity was generally noted 2 to 3 months after renal transplant and consisted of an arrest in the fall of the pre-operative elevations of BUN and creatinine at a range of 35 to 45 mg/dL and 2.0 to 2.5 mg/dL, respectively. These elevations were often responsive to cyclosporine dosage reduction. More overt nephrotoxicity was seen early after transplantation and was characterized by a rapidly rising BUN and creatinine. Since these events are similar to renal rejection episodes, care must be taken to differentiate between them. This form of nephrotoxicity is usually responsive to cyclosporine dosage reduction. Although specific diagnostic criteria which reliably differentiate renal graft rejection from drug toxicity have not been found, a number of parameters have been significantly associated with one or the other. It should be noted however, that up to 20% of patients may have simultaneous nephrotoxicity and rejection. a p < 0.05, b p < 0.01, c p < 0.001, d p < 0.0001 Nephrotoxicity vs. Rejection Parameter Nephrotoxicity Rejection History Donor > 50 years old or hypotensive Prolonged kidney preservation Prolonged anastomosis time Concomitant nephrotoxic drugs Anti-donor immune response Retransplant patient Clinical Often > 6 weeks postop b Prolonged initial nonfunction (acute tubular necrosis) Often < 4 weeks postop b Fever > 37.5°C Weight gain > 0.5 kg Graft swelling and tenderness Decrease in daily urine volume > 500 mL (or 50%) Laboratory CyA serum trough level > 200 ng/mL Gradual rise in Cr (< 0.15 mg/dL/day) a Cr plateau < 25% above baseline BUN/Cr ≥ 20 CyA serum trough level < 150 ng/mL Rapid rise in Cr (> 0.3 mg/dL/day) a Cr > 25% above baseline…

CONTRAINDICATIONS General Neoral is contraindicated in patients with a hypersensitivity to cyclosporine or to any of the ingredients of the formulation. Rheumatoid Arthritis Rheumatoid arthritis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Neoral. Psoriasis Psoriasis patients who are treated with Neoral should not receive concomitant PUVA or UVB therapy, methotrexate or other immunosuppressive agents, coal tar or radiation therapy. Psoriasis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Neoral.

Drug Interactions When diclofenac or methotrexate was coadministered with cyclosporine in rheumatoid arthritis patients, the AUC of diclofenac and methotrexate, each was significantly increased (see PRECAUTIONS, Drug Interactions) . No clinically significant pharmacokinetic interactions occurred between cyclosporine and aspirin, ketoprofen, piroxicam, or indomethacin. Specific Populations Renal Impairment In a study performed in 4 subjects with end-stage renal disease (creatinine clearance < 5 mL/min), an intravenous infusion of 3.5 mg/kg of cyclosporine over 4 hours administered at the end of a hemodialysis session resulted in a mean volume of distribution (Vdss) of 3.49 L/kg and systemic clearance (CL) of 0.369 L/hr/kg. This systemic CL (0.369 L/hr/kg) was approximately two thirds of the mean systemic CL (0.56 L/hr/kg) of cyclosporine in historical control subjects with normal renal function. In 5 liver transplant patients, the mean clearance of cyclosporine on and off hemodialysis was 463 mL/min and 398 mL/min, respectively. Less than 1% of the dose of cyclosporine was recovered in the dialysate. Hepatic Impairment Cyclosporine is extensively metabolized by the liver. Since severe hepatic impairment may result in significantly increased cyclosporine exposures, the dosage of cyclosporine may need to be reduced in these patients. Drug Interactions A. Effect of Drugs and Other Agents on Cyclosporine Pharmacokinetics and/or Safety All of the individual drugs cited below are well substantiated to interact with cyclosporine. In addition, concomitant use of NSAIDs with cyclosporine, particularly in the setting of dehydration, may potentiate renal dysfunction. Caution should be exercised when using other drugs which are known to impair renal function (see WARNINGS, Nephrotoxicity) . Drugs That May Potentiate Renal Dysfunction Antibiotics Antineoplastics Antifungals Anti-inflammatory Drugs Gastrointestinal Agents Immunosuppressives Other Drugs ciprofloxacin melphalan amphotericin B azapropazon cimetidine tacrolimus fibric acid derivatives (e.g., bezafibrate, fenofibrate) gentamicin ketoconazole colchicine ranitidine methotrexate tobramycin diclofenac trimethoprim with sulfamethoxazole naproxen vancomycin sulindac During the concomitant use of a drug that may exhibit additive or synergistic renal impairment with cyclosporine, close monitoring of renal function (in particular serum creatinine) should be performed. If a significant impairment of renal function occurs, the dosage of the coadministered drug should be reduced or an alternative treatment considered. Cyclosporine is extensively metabolized by CYP 3A isoenzymes, in particular CYP3A4, and is a substrate of the multidrug efflux transporter P-glycoprotein. Various agents are known to either increase or decrease plasma or whole blood concentrations of cyclosporine usually by inhibition or induction of CYP3A4 or P-glycoprotein transporter or both. Compounds that decrease cyclosporine absorption, such as orlistat, should be avoided. Appropriate Neoral dosage adjustment to achieve the desired cyclosporine concentrations is essential when drugs that significantly alter cyclosporine concentrations are used concomitantly (see Blood Concentration Monitoring) . 1. Drugs That Increase Cyclosporine Concentrations Calcium Channel Blockers Antifungals Antibiotics Glucocorticoids Other Drugs diltiazem fluconazole azithromycin methylprednisolone Allopurinol nicardipine itraconazole clarithromycin Amiodarone verapamil ketoconazole erythromycin Bromocriptine voriconazole quinupristin/ dalfopristin colchicine danazol imatinib metoclopramide nefazodone oral contraceptives HIV Protease Inhibitors The HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, and saquinavir) are known to inhibit cytochrome P-450 3A and thus could potentially increase the concentrations of cyclosporine, however no formal studies of the interaction are available. Care should be exercised when these drugs are ad…

Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to cyclosporine, including Neoral, during pregnancy. Encourage women who are taking Neoral during pregnancy to enroll in the Transplant Pregnancy Registry International (TPRI) by calling 1-877-955-8677 or visiting https://www.transplantpregnancyregistry.org . Risk Summary Available data from published literature, including the Transplant Pregnancy Registry International, observational cohort studies, case-controlled studies, meta-analysis, case series, and case reports, over decades of use with cyclosporine in pregnancy have not identified a drug associated risk of major birth defects, or miscarriage. Adverse maternal or fetal outcomes including hypertension, preeclampsia, preterm birth, and low birth weight are increased in patients treated with cyclosporine. However, patients receiving cyclosporine during pregnancy have underlying medical conditions and may be treated with concomitant medications that limit the interpretability of these findings (see Data) . Embryo-fetal developmental (EFD) studies in rats and rabbits with cyclosporine have shown embryo-fetal toxicity at dose levels below the MRHD based on BSA. The alcohol content of Neoral should be taken into account when given to pregnant women (see WARNINGS, Special Excipients) . The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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. Data Human Data Available data from the National Transplantation Pregnancy Registry (NTPR) including 622 pregnancies in renal, liver, and heart transplant recipients exposed to cyclosporine during pregnancy found that the overall rate of major birth defects, live birth rates, and miscarriage rates were comparable to the general population. Maternal and fetal adverse outcomes, including the rate of hypertension, preeclampsia, premature births, and low birth weight infants appear to be increased in transplant recipients treated with cyclosporine compared to the general population. However, these patients have underlying medical conditions that confound the above findings. Animal Data Animal studies have shown reproductive toxicity in rats and rabbits. Three EFD studies (two oral and one intravenous) are available in rats. In two EFD studies, pregnant rats were orally administered with cyclosporine either at doses of 10, 17, 30, 100 and 300 mg/kg/day or 4, 10 and 25 mg/kg/day from gestation day (GD) 6 to 15 or from GD 7 to 17, respectively. Maternal toxicity characterized by mortality, clinical signs of toxicity and impaired body weight gain were observed at 30 mg/kg/day and above. Cyclosporine was embryo- and fetotoxic as indicated by increased embryonic mortality and reduced fetal weight together with skeletal retardations in rats at 25 mg/kg/day and above. In addition, ventricular septal defect was observed at 25 mg/kg/day in fetuses. In the first study, the oral no observed effect level (NOEL) for both dams and fetuses was 17 mg/kg/day (0.2 times the MRHD based on BSA). In the other oral study, the NOEL for dams and fetuses were 10 and 4 mg/kg/day (0.13 and 0.05 times the MRHD based on BSA), respectively. In the IV EFD study, rats were administered with 3, 6 and 12 mg/kg/day of cyclosporine from GD 7 to 17. An increase in post implantation loss was observed at 12 mg/kg/day; ventricular septal defect was observed at ≥ 6 mg/kg/day in fetuses. The IV NOEL for dams and fetus were 6 and 3 mg/kg/day (0.08 and 0.04 times the MRHD, respectively, based on BSA), respectively, after IV administration. In rabbits, cyclosporine was orally administered at dose levels of 10, 30, 100 or 300 mg/kg/day from GD 6 to…

Nursing Mothers Risk Summary Cyclosporine and its metabolites are present in human milk following oral and intravenous administration. Adverse effects on the breastfed infant have not been reported. There are no data on the effects of the drug on milk production. The alcohol content of Neoral should be taken into account when given to lactating women (see WARNINGS, Special Excipients) . Lactating women are encouraged to avoid additional alcohol intake during treatment. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Neoral and any potential adverse effects on the breastfed infant from Neoral or from the underlying maternal condition.

ADVERSE REACTIONS Kidney, Liver, and Heart Transplantation The principal adverse reactions of cyclosporine therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia. Hypertension Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients. Glomerular Capillary Thrombosis Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure. The pathologic changes resembled those seen in the hemolytic-uremic syndrome and included thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function. Similar findings have been observed when other immunosuppressives have been employed post-transplantation. Hypomagnesemia Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy. Although magnesium-depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple factors, including hypertension, high dose methylprednisolone, hypocholesterolemia, and nephrotoxicity associated with high plasma concentrations of cyclosporine appear to be related to the neurological manifestations of cyclosporine toxicity. Clinical Studies In controlled studies, the nature, severity, and incidence of the adverse events that were observed in 493 transplanted patients treated with Neoral were comparable with those observed in 208 transplanted patients who received Sandimmune in these same studies when the dosage of the two drugs was adjusted to achieve the same cyclosporine blood trough concentrations. Based on the historical experience with Sandimmune, the following reactions occurred in 3% or greater of 892 patients involved in clinical trials of kidney, heart, and liver transplants.

The following reactions occurred in 2% or less of cyclosporine-treated patients: allergic reactions, anemia, anorexia, confusion, conjunctivitis, edema, fever, brittle fingernails, gastritis, hearing loss, hiccups, hyperglycemia, migraine (Neoral), muscle pain, peptic ulcer, thrombocytopenia, tinnitus. The following reactions occurred rarely: anxiety, chest pain, constipation, depression, hair breaking, hematuria, joint pain, lethargy, mouth sores, myocardial infarction, night sweats, pancreatitis, pruritus, swallowing difficulty, tingling, upper GI bleeding, visual disturbance, weakness, weight loss. Patients receiving immunosuppressive therapies, including cyclosporine and cyclosporine-containing regimens, are at increased risk of infections (viral, bacterial, fungal, parasitic). Both generalized and localized infection…
