MYCOPHENOLATE MOFETIL

Mycophenolate mofetil is an antimetabolite immunosuppressant. It is the 2-morpholinoethyl ester of mycophenolic acid (MPA), an immunosuppressive agent; inosine monophosphate dehydrogenase (IMPDH) inhibitor. The chemical name for mycophenolate mofetil (MMF) is 2-morpholinoethyl (E)-6-(1,3-dihydro-4-hydroxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoate. It has empirical formula of C 23 H 31 NO 7 , a molecular weight of 433.50 and the following structural formula. Mycophenolate mofetil, USP is a white to off-white crystalline powder. It is slightly soluble in water (43 µg/mL at pH 7.4); the solubility increases in acidic medium (4.27 mg/mL at pH 3.6). It is freely soluble in acetone, soluble in methanol, and sparingly soluble in ethanol. The apparent partition coefficient in 1-octanol/water (pH 7.4) buffer solution is 238. The pKa values for MMF are 5.6 for the morpholino group and 8.5 for the phenolic group. Mycophenolate mofetil hydrochloride has a solubility of 65.8 mg/mL in 5% Dextrose Injection USP (D5W). The pH of the reconstituted solution is 2.4 to 4.1. Mycophenolate mofetil for injection is the hydrochloride salt of MMF. The chemical name for the hydrochloride salt of mycophenolate mofetil is 2-morpholinoethyl (E)-6-(1,3-dihydro-4-hydroxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoate hydrochloride. It has empirical formula of C 23 H 31 NO 7 HCl and a molecular weight of 469.96. Mycophenolate mofetil for injection, USP is available as a sterile, white to off-white lyophilized powder in single-dose vials containing mycophenolate mofetil hydrochloride for administration by intravenous infusion only. Each vial contains 500 mg of mycophenolate mofetil, USP equivalent to 542 mg of mycophenolate mofetil hydrochloride. The inactive ingredients are polysorbate 80, 25 mg and citric acid anhydrous, 5 mg. Sodium hydroxide or hydrochloric acid may have been used in the manufacture of mycophenolate mofetil for injection, USP to adjust the pH. Reconstitution and dilution with 5% Dextrose Injection USP yields a slightly yellow solution of mycophenolate mofetil, 6 mg/mL [see Dosage and Administration (2.6) ]. structure

In kidney transplant patients with severe chronic impairment of the graft (GFR < 25 mL/min/1.73 m 2 ), do not administer doses of mycophenolate mofetil greater than 1 g twice a day. These patients should be carefully monitored [see Clinical Pharmacology (12.3) ]. Neutropenia If neutropenia develops (ANC < 1.3 x 10 3 /μL), dosing with mycophenolate mofetil should be interrupted or reduced, appropriate diagnostic tests performed, and the patient managed appropriately [see Warnings and Precautions (5.4) and Adverse Reactions (6.1) ]. 2.6 Preparation Instructions of Intravenous for Pharmacists General Preparation Instructions Before Handling the Formulations Mycophenolate mofetil (MMF) has demonstrated teratogenic effects in humans. Follow applicable special handling and disposal procedures. 1 [see Warnings and Precautions (5.1) , Adverse Reactions (6.2) , Use in Specific Populations (8.1 , 8.3) , How Supplied/Storage and Handling (16.1) ]. Care should be taken to avoid inhalation or direct contact with skin or mucous membranes of the dry powder contained in mycophenolate mofetil for injection because MMF has demonstrated teratogenic effects in humans . Wearing disposable gloves is recommended during reconstitution of mycophenolate mofetil for injection and when wiping the outer surface of the vial and the table surface after reconstitution. If such contact occurs, wash hands thoroughly with soap and water; rinse eyes with water. Mycophenolate Mofetil for Injection Before proceeding with the preparation steps for mycophenolate mofetil for injection read the general preparation instructions [see General Preparation Instructions Before Handling the Formulation] and note the following: Mycophenolate mofetil for injection does not contain an antibacterial preservative; therefore, reconstitution and dilution of the product must be performed under aseptic conditions. This product is sealed under vacuum and should retain a vacuum throughout its shelf life. If a lack of vacuum in the vial is noted while adding the diluent, the vial should not be used. Mycophenolate mofetil for injection must be reconstituted and further diluted. A detailed description of the preparation is given below. Table 4 Preparation Instructions of Mycophenolate Mofetil for Injection for Pharmacists Preparation of the 1 g dose Reconstitute two (2) vials of mycophenolate mofetil for injection by injecting 14 mL of 5% Dextrose Injection USP into each vial. Gently shake the vial to dissolve the drug. Inspect the resulting slightly yellow solution for particulate matter and discoloration prior to further dilution. Discard the vials if particulate matter or discoloration is observed. Dilute the contents of the two reconstituted vials (approximately 2 x 15 mL) into 140 mL of 5% Dextrose Injection USP. Inspect the resulting infusion solution and discard if particulate matter or discoloration is observed. Preparation of the 1.5 g dose Reconstitute three (3) vials of mycophenolate mofetil for injection by injecting 14 mL of 5% Dextrose Injection USP into each vial. Gently shake the vial to dissolve the drug. Inspect the resulting slightly yellow solution for particulate matter and discoloration prior to further dilution. Discard the vials if particulate matter or discoloration is observed. Dilute the contents of the three reconstituted vials (approximately 3 x 15 mL) into 210 mL of 5% Dextrose Injection USP. Inspect the resulting infusion solution and discard if particulate matter or discoloration is observed. The administration of the infusion should be initiated within 4 hours of reconstitution and dilution of the drug product. Keep solutions at 25°C (77°F); excursions permitted to 15° to 30°C (59° to 86°F). Discard unused portion of the reconstituted solutions.

An estimated total of 1557 adult patients received mycophenolate mofetil during pivotal clinical trials in the prevention of acute organ rejection. Of these, 991 were included in the three renal studies, 277 were included in one hepatic study, and 289 were included in one cardiac study. Patients in all study arms also received cyclosporine and corticosteroids. The data described below primarily derive from five randomized, active-controlled double-blind 12-month trials of mycophenolate mofetil in de novo kidney (3) heart (1) and liver (1) transplant patients [see Clinical Studies (14.1 , 14.2 and 14.3) ] . Mycophenolate Mofetil Oral The incidence of adverse reactions for mycophenolate mofetil was determined in five randomized, comparative, double-blind trials in the prevention of rejection in kidney, heart and liver transplant patients (two active- and one placebo-controlled trials, one active-controlled trial, and one active-controlled trial, respectively) [see Clinical Studies (14.1 , 14.2 and 14.3) ] . The three de novo kidney studies with 12-month duration compared two dose levels of oral mycophenolate mofetil (1 g twice daily and 1.5 g twice daily) with azathioprine (2 studies) or placebo (1 study) when administered in combination with cyclosporine (Sandimmune ® ) and corticosteroids to prevent acute rejection episodes. One study also included anti-thymocyte globulin (ATGAM ® ) induction therapy. In the de novo heart transplantation study with 12-month duration, patients received mycophenolate mofetil 1.5 g twice daily (n=289) or azathioprine 1.5 to 3 mg/kg/day (n=289), in combination with cyclosporine (Sandimmune ® or Neoral ® ) and corticosteroids as maintenance immunosuppressive therapy. In the de novo liver transplantation study with 12-month duration, patients received mycophenolate mofetil 1 g twice daily intravenously for up to 14 days followed by mycophenolate mofetil 1.5 g twice daily orally or azathioprine 1 to 2 mg/kg/day intravenously followed by azathioprine 1 to 2 mg/kg/day orally, in combination with cyclosporine (Neoral ® ) and corticosteroids as maintenance immunosuppressive therapy. The total number of patients enrolled was 565. Approximately 53% of the kidney transplant patients, 65% of the heart transplant patients, and 48% of the liver transplant patients were treated for more than 1 year. Adverse reactions reported in > 20% of patients in the mycophenolate mofetil treatment groups are presented below. The safety data of three kidney transplantation studies are pooled together.

In the three de novo kidney studies, patients receiving 2 g/day of mycophenolate mofetil had an overall better safety profile than did patients receiving 3 g/day of mycophenolate mofetil. Post-transplant lymphoproliferative disease (PTLD, pseudolymphoma) developed in 0.4% to 1% of patients receiving mycophenolate mofetil (2 g or 3 g daily) with other immunosuppressive agents in controlled clinical trials of kidney, heart and liver transplant patients followed for at least 1 year [see Warnings and Precautions (5.2) ]. Non-melanoma skin carcinomas occurred in 1.6% to 4.2% of patients, other types of malignancy in 0.7% to 2.1% of patients. Three-year safety data in kidney and heart transplant patients did not reveal any unexpected changes in incidence of malignancy compared to the 1-year data. In pediatric patients, PTLD was observed in 1.35% (2/148) by 12 months post-transplant. Cytopenias, including leukopenia, anemia, thrombocytopenia and pancytopenia are a known risk associated with mycophenolate and may lead or contribute to the occurrence of infections and hemorrhages [see Warnings and Precautions (5.3) ] . Severe neutropenia (ANC < 0.5 x 10 3 /μL) developed in up to 2% of kidney transplant patients, up to 2.8% of heart transplant patients and up to 3.6% of liver transplant patients receiving mycophenolate mofetil 3 g daily [see Warnings and Precautions (5.4) and Dosage and Administration (2.5) ]. The most common opportunistic infections in patients receiving mycophenolate mofetil with other immunosuppressants were mucocutaneous candida, CMV viremia/syndrome, and herpes simplex. The proportion of patients with CMV viremia/syndrome was 13.5%. In patients receiving mycophenolate mofetil (2 g or 3 g) in controlled studies for prevention of kidney, heart or liver rejection, fatal infection/sepsis occurred in approximately 2% of kidney and heart patients and in 5% of liver patients [see Warnings and Precautions (5.3) ]. The most serious gastrointestinal disorders reported were ulceration and hemorrhage, which are known risks associated with mycophenolate mofetil. Mouth, esophageal, gastric, duodenal, and intestinal ulcers often complicated by hemorrhage, as well as hematemesis, melena, and hemorrhagic forms of gastritis and colitis were commonly reported during the pivotal clinical trials, while the most common gastrointestinal disorders were diarrhea, nausea and vomiting. Endoscopic investigation of patients with mycophenolate mofetil-related diarrhea revealed isolated cases of intestinal villous atrophy [see Warnings and Precautions (5.5) ] . The following adverse reactions were reported with 3% to < 20% incidence in kidney, heart, and liver transplant patients treated with mycophenolate mofetil, in combination with cyclosporine and corticosteroids. Table 6 Adverse Reactions in Controlled Studies of De Novo Kidney, Heart or Liver Transplantation Reported in 3% to < 20% of Patients Treated with Mycophenolate Mofetil in Combination with Cyclosporine and Corticosteroids System Organ Class Adverse Reactions Body as a Whole cellulitis, chills, hernia, malaise Infections and Infestations fungal infections Hematologic and Lymphatic coagulation disorder, ecchymosis, pancytopenia Urogenital hematuria Cardiovascular hypotension Metabolic and Nutritional acidosis, alkaline phosphatase increased, hyperlipemia, hypophosphatemia, weight loss Digestive esophagitis, flatulence, gastritis, gastrointestinal hemorrhage, hepatitis, ileus, nausea and vomiting, stomach ulcer, stomatitis Neoplasm benign, malignant and unspecified neoplasm Skin and Appendages skin benign neoplasm, skin carcinoma Psychiatric confusional state Nervous hypertonia, paresthesia, somnolence Musculoskeletal arthralgia, myasthenia Pediatric Study The type and frequency of adverse events in a clinical study for prevention of kidney allograft rejection in 100 pediatric patients 3 months to 18 years of age dosed with mycophenolate mofetil oral suspension 600 mg/m 2 twice daily (up to 1 g twice daily) were generally similar to those observed in adult patients dosed with mycophenolate mofetil capsules at a dose of 1 g twice daily with the exception of abdominal pain, fever, infection, pain, sepsis, diarrhea, vomiting, pharyngitis, respiratory tract infection, hypertension, leukopenia, and anemia, which were observed in a higher proportion in pediatric patients. Safety information in pediatric heart transplant or pediatric liver transplant patients treated with mycophenolate mofetil is supported by an open-label study in pediatric liver transplant patients and publications; the type and frequency of the reported adverse reactions are consistent with those observed in pediatric patients following renal transplant and in adults. Geriatrics Geriatric patients (≥ 65 years), particularly those who are receiving mycophenolate mofetil as part of a combination immunosuppressive regimen, may be at increased risk of certain infections (including cytomegalovirus [CMV] tissue invasive disease) and possibly gastrointestinal hemorrhage and pulmonary edema, compared to younger individuals [see Warnings and Precautions (5.3) and Adverse Reactions (6.1) ]. Mycophenolate Mofetil for Injection The safety profile of mycophenolate mofetil for injection was determined from a single, double-blind, controlled comparative study of the safety of 2 g/day of intravenous and oral mycophenolate mofetil in kidney transplant patients in the immediate post-transplant period (administered for the first 5 days). The potential venous irritation of mycophenolate mofetil for injection was evaluated by comparing the adverse reactions attributable to peripheral venous infusion of mycophenolate mofetil for injection with those observed in the intravenous placebo group; patients in the placebo group received active medication by the oral route. Adverse reactions attributable to peripheral venous infusion were phlebitis and thrombosis, both observed at 4% in patients treated with mycophenolate mofetil for injection. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of mycophenolate mofetil. 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: Embryo-Fetal Toxicity : Congenital malformations and spontaneous abortions, mainly in the first trimester, have been reported following exposure to mycophenolate mofetil (MMF) in combination with other immunosuppressants during pregnancy [see Warnings and Precautions (5.1) , and Use in Specific Populations (8.1) , (8.3) ]. Congenital malformations include: - Facial malformations: cleft lip, cleft palate, micrognathia, hypertelorism of the orbits - Abnormalities of the ear and eye: abnormally formed or absent external/middle ear, coloboma, microphthalmos - Malformations of the fingers: polydactyly, syndactyly, brachydactyly - Cardiac abnormalities: atrial and ventricular septal defects - Esophageal malformations: esophageal atresia - Nervous system malformations: such as spina bifida . Cardiovascular : Venous thrombosis has been reported in patients treated with mycophenolate mofetil administered intravenously. Digestive : Colitis, pancreatitis Hematologic and Lymphatic : Bone marrow failure, cases of pure red cell aplasia (PRCA) and hypogammaglobulinemia have been reported in patients treated with mycophenolate mofetil in combination with other immunosuppressive agents [see Warnings and Precautions (5.4) ] . Immune : Hypersensitivity reactions, including anaphylaxis and angioedema [see Warnings and Precautions (5.8)], hypogammaglobinemia. Infections : Meningitis, infectious endocarditis, tuberculosis, atypical mycobacterial infection, progressive multifocal leukoencephalopathy, BK virus infection, viral reactivation of hepatitis B and hepatitis C, protozoal infections [see Warnings and Precautions (5.3) ] . Respiratory : Bronchiectasis, interstitial lung disease, fatal pulmonary fibrosis, have been reported rarely and should be considered in the differential diagnosis of pulmonary symptoms ranging from dyspnea to respiratory failure in post-transplant patients receiving mycophenolate mofetil. Vascular : Lymphocele

See FPI for drugs that may interfere with systemic exposure and reduce Mycophenolate mofetil for injection efficacy: antacids with magnesium or aluminum hydroxide, proton pump inhibitors, drugs that interfere with enterohepatic recirculation, telmisartan, calcium-free phosphate binders. (7.1) Mycophenolate mofetil for injection may reduce effectiveness of oral contraceptives. Use of additional barrier contraceptive methods is recommended. (7.2) See FPI for other important drug interactions. (7) 7.1 Effect of Other Drugs on Mycophenolate Mofetil for Injection Table 7 Drug Interactions with Mycophenolate Mofetil that Affect Mycophenolic Acid (MPA) Exposure Antacids with Magnesium or Aluminum Hydroxide Clinical Impact Concomitant use with an antacid containing magnesium or aluminum hydroxide decreases MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Administer magnesium or aluminum hydroxide containing antacids at least 2h after mycophenolate mofetil administration. Proton Pump Inhibitors (PPIs) Clinical Impact Concomitant use with PPIs decreases MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Monitor patients for alterations in efficacy when PPIs are co-administered with mycophenolate mofetil. Examples Lansoprazole, pantoprazole Drugs that Interfere with Enterohepa tic Recirculation Clinical Impact Concomitant use with drugs that directly interfere with enterohepatic recirculation, or indirectly interfere with enterohepatic recirculation by altering the gastrointestinal flora, can decrease MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Monitor patients for alterations in efficacy or mycophenolate mofetil related adverse reactions when these drugs are co-administered with mycophenolate mofetil. Examples Cyclosporine A, trimethoprim/sulfamethoxazole, bile acid sequestrants (cholestyramine), rifampin as well as aminoglycoside, cephalosporin, fluoroquinolone and penicillin classes of antimicrobials Drugs Modulating Glucuronidation Clinical Impact Concomitant use with drugs inducing glucuronidation decreases MPA systemic exposure, potentially reducing mycophenolate mofetil efficacy, while use with drugs inhibiting glucuronidation increases MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may increase the risk of mycophenolate mofetil related adverse reactions. Prevention or Management Monitor patients for alterations in efficacy or mycophenolate mofetil related adverse reactions when these drugs are co-administered with mycophenolate mofetil. Examples Telmisartan (induces glucuronidation); isavuconazole (inhibits glucuronidation). Calcium Free Phosph ate Binders Clinical Impact Concomitant use with calcium free phosphate binders decrease MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Administer calcium free phosphate binders at least 2 hours after mycophenolate mofetil. Examples Sevelamer 7.2 Effect of Mycophenolate Mofetil on Other Drugs Table 8 Drug Interactions with Mycophenolate Mofetil that Affect Other Drugs Drugs that Undergo Renal Tubular Secretion Clinical Impact When concomitantly used with mycophenolate mofetil, its metabolite MPAG, may compete with drugs eliminated by renal tubular secretion which may increase plasma concentrations and/or adverse reactions associated with these drugs. Prevention or Management Monitor for drug-related adverse reactions in patients with renal impairment. Examples Acyclovir, ganciclovir, probenecid, valacyclovir, valganciclovir Combination Oral Contraceptives Clinical Impact Concomitant use with mycophenolate mofetil decreased the systemic exposure to levonorgestrel, but did not affect the systemic exposure to ethinylestradiol [see Clinical Pharmacology (12.3) ] , which may result in reduced combination oral contraceptive effectiveness. Prevention or Management Use additional barrier contraceptive methods.
