1 INDICATIONS AND USAGE
Mycophenolate mofetil capsules are indicated for the prophylaxis of organ rejection, in adult and pediatric recipients 3 months of age and older of allogeneic kidney [see Clinical Studies (14.1)], heart [see Clinical Studies (14.2)] or liver transplants [see Clinical Studies (14.3)], in combination with other immunosuppressants.
Mycophenolate Mofetil capsules are an antimetabolite immunosuppressant indicated for the prophylaxis of organ rejection in adult and pediatric recipients 3 months of age and older of allogeneic kidney, heart or liver transplants, in combination with other immunosuppressants. ( 1)
CONTRAINDICATIONS SECTION
4 CONTRAINDICATIONS
Mycophenolate mofetil capsule is contraindicated in patients with a history of hypersensitivity, including anaphylaxis, to mycophenolate mofetil (MMF), mycophenolic acid (MPA) or any component of the drug product [see Warnings and Precautions ( 5.8)].
• History of hypersensitivity, including anaphylaxis, to mycophenolate mofetil, mycophenolic acid or any component of the drug product (4)
WARNINGS AND PRECAUTIONS SECTION
5 WARNINGS AND PRECAUTIONS
5.1 Embryofetal Toxicity
Use of MMF during pregnancy is associated with an increased risk of first trimester pregnancy loss and an increased risk of congenital malformations, especially external ear and other facial abnormalities including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, kidney and nervous system. Females of reproductive potential must be made aware of these risks and must be counseled regarding pregnancy prevention and planning. Avoid use of MMF during pregnancy if safer treatment options are available [see Use in Specific Populations (8.1, 8.3)].
5.2 Lymphoma and Other Malignancies
Patients receiving immunosuppressants, including mycophenolate mofetil, are at
increased risk of developing lymphomas and other malignancies, particularly of
the skin [see Adverse Reactions (6.1)] . The risk appears to be related to the
intensity and duration of immunosuppression rather than to the use of any
specific agent. For patients with increased risk for skin cancer, exposure to
sunlight and UV light should be limited by wearing protective clothing and
using a broad-spectrum sunscreen with a high protection factor.
Post-transplant lymphoproliferative disorder (PTLD) developed in 0.4% to 1% of
patients receiving mycophenolate mofetil (2 g or 3 g) with other
immunosuppressive agents in controlled clinical trials of kidney, heart and
liver transplant patients [see Adverse Reactions (6.1)]. The majority of PTLD
cases appear to be related to Epstein Barr Virus (EBV) infection. The risk of
PTLD appears greatest in those individuals who are EBV seronegative, a
population which includes many young children. In pediatric patients, no other
malignancies besides PTLD were observed in clinical trials [see Adverse Reactions (6.1)].
5.3 Serious Infections
Patients receiving immunosuppressants, including mycophenolate mofetil, are at
increased risk of developing bacterial, fungal, protozoal and new or
reactivated viral infections, including opportunistic infections. The risk
increases with the total immunosuppressive load. These infections may lead to
serious outcomes, including hospitalizations and death [see Adverse Reactions (6.1, 6.2)].
Serious viral infections reported include:
• Polyomavirus-associated nephropathy (PVAN), especially due to BK virus
infection
• JC virus-associated progressive multifocal leukoencephalopathy (PML), and
• Cytomegalovirus (CMV) infections: CMV seronegative transplant patients who
receive an organ from a CMV seropositive donor are at highest risk of CMV
viremia and CMV disease.
• Viral reactivation in patients infected with Hepatitis B and C
• COVID-19
Consider dose reduction or discontinuation of mycophenolate mofetil in
patients who develop new infections or reactivate viral infections, weighing
the risk that reduced immunosuppression represents to the functioning
allograft.
PVAN, especially due to BK virus infection, is associated with serious
outcomes, including deteriorating renal function and renal graft loss [see Adverse Reactions (6.2)] . Patient monitoring may help detect patients at risk
for PVAN.
PML, which is sometimes fatal, commonly presents with hemiparesis, apathy,
confusion, cognitive deficiencies, and ataxia [see Adverse Reactions (6.2)].
In immunosuppressed patients, physicians should consider PML in the
differential diagnosis in patients reporting neurological symptoms.
The risk of CMV viremia and CMV disease is highest among transplant recipients
seronegative for CMV at time of transplant who receive a graft from a CMV
seropositive donor. Therapeutic approaches to limiting CMV disease exist and
should be routinely provided. Patient monitoring may help detect patients at
risk for CMV disease.
Viral reactivation has been reported in patients infected with HBV or HCV.
Monitoring infected patients for clinical and laboratory signs of active HBV
or HCV infection is recommended.
5.4 Blood Dyscrasias: Neutropenia and Pure Red Cell Aplasia (PRCA)
Severe neutropenia [absolute neutrophil count (ANC) <0.5 x 10 3/µL] developed
in transplant patients receiving mycophenolate mofetil 3 g dail y [see Adverse Reactions (6.1)] . Patients receiving mycophenolate mofetil should be
monitored for neutropenia. Neutropenia has been observed most frequently in
the period from 31 to 180 days post-transplant in patients treated for
prevention of kidney, heart and liver rejection. The development of
neutropenia may be related to mycophenolate mofetil itself, concomitant
medications, viral infections, or a combination of these causes. If
neutropenia develops (ANC <1.3 x 10 3/µL), dosing with mycophenolate mofetil
should be interrupted or the dose reduced, appropriate diagnostic tests
performed, and the patient managed appropriately [see Dosage and Administration (2.5)].
Patients receiving mycophenolate mofetil should be instructed to report
immediately any evidence of infection, unexpected bruising, bleeding or any
other manifestation of bone marrow depression.
Consider monitoring with complete blood counts weekly for the first month,
twice monthly for the second and third months, and monthly for the remainder
of the first year.
Cases of pure red cell aplasia (PRCA) have been reported in patients treated
with mycophenolate mofetil in combination with other immunosuppressive agents.
In some cases, PRCA was found to be reversible with dose reduction or
cessation of mycophenolate mofetil therapy. In transplant patients, however,
reduced immunosuppression may place the graft at risk.
5.5 Gastrointestinal Complications
Gastrointestinal bleeding requiring hospitalization, ulceration and perforations were observed in clinical trials. Physicians should be aware of these serious adverse effects particularly when administering mycophenolate mofetil to patients with a gastrointestinal disease.
5.6 Patients with Hypoxanthine-Guanine Phosphoribosyl-Transferase
Deficiency (HGPRT)
Mycophenolate mofetil is an inosine monophosphate dehydrogenase (IMPDH) inhibitor; therefore it should be avoided in patients with hereditary deficiencies of hypoxanthine-guanine phosphoribosyl-transferase (HGPRT) such as Lesch-Nyhan and Kelley-Seegmiller syndromes because it may cause an exacerbation of disease symptoms characterized by the overproduction and accumulation of uric acid leading to symptoms associated with gout such as acute arthritis, tophi, nephrolithiasis or urolithiasis and renal disease including renal failure.
5.7 Acute Inflammatory Syndrome Associated with Mycophenolate Products
Acute inflammatory syndrome (AIS) has been reported with the use of MMF and
mycophenolate products, and some cases have resulted in hospitalization. AIS
is a paradoxical pro-inflammatory reaction characterized by fever,
arthralgias, arthritis, muscle pain and elevated inflammatory markers
including, C-reactive protein and erythrocyte sedimentation rate, without
evidence of infection or underlying disease recurrence. Symptoms occur within
weeks to months of initiation of treatment or a dose increase. After
discontinuation, improvement of symptoms and inflammatory markers are usually
observed within 24 to 48 hours.
Monitor patients for symptoms and laboratory parameters of AIS when starting
treatment with mycophenolate products or when increasing the dosage.
Discontinue treatment and consider other treatment alternatives based on the
risk and benefit for the patient.
5.8 Hypersensitivity Reactions
Postmarketing cases of hypersensitivity reactions, including angioedema and anaphylaxis, have been reported with mycophenolate mofetil. These reactions generally occurred within hours to the next day after initiating mycophenolate mofetil. If signs or symptoms of hypersensitivity reaction occur, discontinue mycophenolate mofetil; treat and monitor until symptoms resolve [see Contraindications ( 4)].
5.9 Immunizations
During treatment with mycophenolate mofetil, the use of live attenuated vaccines should be avoided (e.g., intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella, and TY21a typhoid vaccines) and patients should be advised that vaccinations may be less effective. Advise patients to discuss with the physician before seeking any immunizations.
5.12 Blood Donation
Patients should not donate blood during therapy and for at least 6 weeks following discontinuation of mycophenolate mofetil because their blood or blood products might be administered to a female of reproductive potential or a pregnant woman.
5.13 Semen Donation
Based on animal data, men should not donate semen during therapy and for 90 days following discontinuation of mycophenolate mofetil [see Use In Specific Populations (8.3)].
5.14 Effect of Concomitant Medications on Mycophenolic Acid Concentrations
A variety of drugs have potential to alter systemic MPA exposure when co- administered with mycophenolate mofetil. Therefore, determination of MPA concentrations in plasma before and after making any changes to immunosuppressive therapy, or when adding or discontinuing concomitant medications, may be appropriate to ensure MPA concentrations remain stable.
5.15 Potential Impairment of Ability to Drive or Operate Machinery
Mycophenolate mofetil may impact the ability to drive and use machines. Patients should avoid driving or using machines if they experience somnolence, confusion, dizziness, tremor, or hypotension during treatment with mycophenolate mofetil [see Adverse Reactions (6.1)].
• Blood Dyscrasias (Neutropenia, Red Blood Cell Aplasia): Monitor with blood
tests; consider treatment interruption or dose reduction. ( 5.4)
• Gastrointestinal Complications: Monitor for complications such as bleeding,
ulceration and perforations, particularly in patients with underlying
gastrointestinal disorders. ( 5.5)
• Hypoxanthine-Guanine Phosphoribosyl-Transferase Deficiency: Avoid use of
mycophenolate mofetil. ( 5.6)
• Acute Inflammatory Syndrome Associated with Mycophenolate Products: Monitor
for this paradoxical inflammatory reaction. ( 5.7)
• Hypersensitivity Reactions: Discontinue mycophenolate mofetil; treat and
monitor until signs and symptoms resolve. ( 5.8)
• Immunizations: Avoid live attenuated vaccines. ( 5.9)
• Blood Donation: Avoid during therapy and for 6 weeks thereafter. ( 5.12)
• Semen Donation: Avoid during therapy and for 90 days thereafter. ( 5.13)
• Potential Impairment on Driving and Use of Machinery: Mycophenolate mofetil
may affect ability to drive or operate machinery. ( 5.15)

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse
reaction rates observed in the clinical trials of a drug cannot be directly
compared to rates in the clinical trials of another drug and may not reflect
the rates observed in practice.
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
novokidney (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 novokidney 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 novoheart 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 novoliver 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.

c: “Pain” includes musculoskeletal pain (myalgia, neck pain, back pain).
In the three de novokidney 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.

Pediatrics
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 2twice 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 Intravenous
The safety profile of mycophenolate mofetil intravenous 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 intravenous was evaluated
by comparing the adverse reactions attributable to peripheral venous infusion
of mycophenolate mofetil intravenous 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 intravenous.
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

DOSAGE & ADMINISTRATION SECTION
2 DOSAGE AND ADMINISTRATION
2.1 Important Administration Instructions
Mycophenolate mofetil should not be used without the supervision of a
physician with experience in immunosuppressive therapy.
Mycophenolate Mofetil Capsules
Mycophenolate mofetil capsulesshould not be used interchangeably with
mycophenolic acid delayed-release tablets without supervision of a physician
with experience in immunosuppressive therapybecause the rates of absorption
following the administration of mycophenolate mofetil capsule and mycophenolic
acid delayed-release tablets are not equivalent.
Mycophenolate mofetil capsules should not be opened or crushed. Patients
should avoid inhalation or contact of the skin or mucous membranes with the
powder contained in Mycophenolate mofetil capsules. If such contact occurs,
they must wash the area of contact thoroughly with soap and water. In case of
ocular contact, rinse eyes with plain water.
The initial oral dose of mycophenolate mofetil capsules should be given as
soon as possible following kidney, heart or liver transplant. It is
recommended that mycophenolate mofetil capsules be administered on an empty
stomach. In stable transplant patients, however, mycophenolate mofetil
capsules may be administered with food if necessary [see Clinical Pharmacology (12.3)].
Patients should be instructed to take a missed dose as soon as they remember,
except if it is closer than 2 hours to the next scheduled dose; in this case,
they should continue to take mycophenolate mofetil capsules at the usual
times.
2.2 Dosage Recommendations for Kidney Transplant Patients
Adults
The recommended dosage for adult kidney transplant patients is 1 g orally,
twice daily (total daily dose of 2 g).

USE IN SPECIFIC POPULATIONS SECTION
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in
women exposed to mycophenolate during pregnancy and those becoming pregnant
within 6 weeks of discontinuing mycophenolate mofetil treatment. To report a
pregnancy or obtain information about the registry, visit
www.mycophenolateREMS.comor call 1-800-617-8191.
Risk Summary
Use of mycophenolate mofetil (MMF) during pregnancy is associated with an
increased risk of first trimester pregnancy loss and an increased risk of
multiple congenital malformations in multiple organ systems [see Human Data].
Oral administration of mycophenolate to rats and rabbits during the period of
organogenesis produced congenital malformations and pregnancy loss at doses
less than the recommended clinical dose (0.01 to 0.05 times the recommended
clinical doses in kidney and heart transplant patients) [see Animal Data].
Consider alternative immunosuppressants with less potential for embryofetal toxicity. Risks and benefits of mycophenolate mofetil should be discussed with the pregnant woman.
The estimated background risk of pregnancy loss and congenital malformations
in organ transplant populations is not clear. 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
A spectrum of congenital malformations (including multiple malformations in
individual newborns) has been reported in 23 to 27% of live births in MMF
exposed pregnancies, based on published data from pregnancy registries.
Malformations that have been documented include external ear, eye, and other
facial abnormalities including cleft lip and palate, and anomalies of the
distal limbs, heart, esophagus, kidney, and nervous system.
Based on published data from pregnancy registries, the risk of first trimester
pregnancy loss has been reported at 45 to 49% following MMF exposure.
Animal Data
In animal reproductive toxicology studies, there were increased rates of fetal
resorptions and malformations in the absence of maternal toxicity. Oral
administration of MMF to pregnant rats from Gestational Day 7 to Day 16
produced increased embryofetal lethality and fetal malformations including
anophthalmia, agnathia, and hydrocephaly at doses equivalent to 0.015 and 0.01
times the recommended human doses for renal and cardiac transplant patients,
respectively, when corrected for BSA. Oral administration of MMF to pregnant
rabbits from Gestational Day 7 to Day 19 produced increased embryofetal
lethality and fetal malformations included ectopia cordis, ectopic kidneys,
diaphragmatic hernia, and umbilical hernia at dose equivalents as low as 0.05
and 0.03 times the recommended human doses for renal and cardiac transplant
patients, respectively, when corrected for BSA.
8.2 Lactation
Risk Summary
There are no data on the presence of mycophenolate in human milk, or the
effects on milk production. There are limited data in the National
Transplantation Pregnancy Registry on the effects of mycophenolate on a
breastfed child [see Data]. Studies in rats treated with MMF have shown
mycophenolic acid (MPA) to be present in milk. Because available data are
limited, it is not possible to exclude potential risks to a breastfeeding
infant.
The developmental and health benefits of breastfeeding should be considered
along with the mother’s clinical need for mycophenolate mofetil and any
potential adverse effects on the breastfed infant from mycophenolate mofetil
or from the underlying maternal condition.
Data
Limited information is available from the National Transplantation Pregnancy
Registry. Of seven infants reported by the National Transplantation Pregnancy
Registry to have been breastfed while the mother was taking mycophenolate, all
were born at 34 to 40 weeks gestation, and breastfed for up to 14 months. No
adverse events were reported.
8.3 Females and Males of Reproductive Potential
Females of reproductive potential must be made aware of the increased risk of
first trimester pregnancy loss and congenital malformations and must be
counseled regarding pregnancy prevention and planning.
Pregnancy Planning
For patients who are considering pregnancy, consider alternative
immunosuppressants with less potential for embryofetal toxicity whenever
possible. Risks and benefits of mycophenolate mofetil should be discussed with
the patient.
Pregnancy Testing
To prevent unplanned exposure during pregnancy, all females of reproductive
potential should have a serum or urine pregnancy test with a sensitivity of at
least 25 mIU/mL immediately before starting mycophenolate mofetil. Another
pregnancy test with the same sensitivity should be done 8 to 10 days later.
Repeat pregnancy tests should be performed during routine follow-up visits.
Results of all pregnancy tests should be discussed with the patient. In the
event of a positive pregnancy test, consider alternative immunosuppressants
with less potential for embryofetal toxicity whenever possible.
Contraception
Female Patients
Females of reproductive potential taking mycophenolate mofetil must receive
contraceptive counseling and use acceptable contraception (seeTable 9for
acceptable contraception methods). Patients must use acceptable birth control
during the entire mycophenolate mofetil therapy, and for 6 weeks after
stopping mycophenolate mofetil, unless the patient chooses abstinence.
Patients should be aware that mycophenolate mofetil reduces blood levels of
the hormones from the oral contraceptive pill and could theoretically reduce
its effectiveness [see Drug Interactions (7.2)].

Male Patients
Genotoxic effects have been observed in animal studies at exposures exceeding the human therapeutic exposures by approximately 1.25 times. Thus, the risk of genotoxic effects on sperm cells cannot be excluded. Based on this potential risk, sexually active male patients and/or their female partners are recommended to use effective contraception during treatment of the male patient and for at least 90 days after cessation of treatment. Also, based on the potential risk of genotoxic effects, male patients should not donate sperm during treatment with mycophenolate mofetil and for at least 90 days after cessation of treatment [see Use in Special Populations (8.1), Nonclinical Toxicology (13.1), Patient Counseling Information (17.9)].
8.4 Pediatric Use
Safety and effectiveness have been established in pediatric patients 3 months
and older for the prophylaxis of organ rejection of allogenic kidney, heart or
liver transplants.
Kidney Transplant
Use of mycophenolate mofetil in this population is supported by evidence from
adequate and well-controlled studies of mycophenolate mofetil in adults with
additional data from one open-label, pharmacokinetic and safety study of
mycophenolate mofetil in pediatric patients after receiving allogeneic kidney
transplant (100 patients, 3 months to 18 years of age) [see Dosage and Administration (2.2), Adverse Reactions (6.1), Clinical Pharmacology (12.3), Clinical Studies (14.1)].
Heart Transplant and Liver Transplant
Use of mycophenolate mofetil in pediatric heart transplant and liver
transplant patients is supported by adequate and well-controlled studies and
pharmacokinetic data in adult heart transplant and liver transplant patients.
Additional supportive data include pharmacokinetic data in pediatric kidney
transplant and pediatric liver transplant patients (8 liver transplant
patients, 9 months to 5 years of age, in an open-label, pharmacokinetic and
safety study) and published evidence of clinical efficacy and safety in
pediatric heart transplant and pediatric liver transplant patients [see Dosage and Administration (2.3, 2.4), Adverse Reactions (6.1), Clinical Pharmacology (12.3), Clinical Studies (14.1)].
8.5 Geriatric Use
Clinical studies of mycophenolate mofetil did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between geriatric and younger patients. In general, dose selection for a geriatric patient should take into consideration the presence of decreased hepatic, renal or cardiac function and of concomitant drug therapies [see Adverse Reactions (6.1), Drug Interactions (7)].
8.6 Patients with Renal Impairment
Patients with Kidney Transplant
No dosage adjustments are needed in kidney transplant patients experiencing
delayed graft function postoperatively but patients should be carefully
monitored [see Clinical Pharmacology (12.3)]. In kidney transplant patients
with severe chronic impairment of the graft(GFR <25 mL/min/1.73 m 2), no dose
adjustments are necessary; however, doses greater than 1 g administered twice
a day should be avoided.
Patients with Heart and Liver Transplant
No data are available for heart or liver transplant patients with severe
chronic renal impairment. Mycophenolate mofetil may be used for heart or liver
transplant patients with severe chronic renal impairment if the potential
benefits outweigh the potential risks.
8.7 Patients with Hepatic Impairment
Patients with Kidney Transplant
No dosage adjustments are recommended for kidney transplant patients with
severe hepatic parenchymal disease. However, it is not known whether dosage
adjustments are needed for hepatic disease with other etiologies [see Clinical Pharmacology (12.3)].
Patients with Heart Transplant
No data are available for heart transplant patients with severe hepatic
parenchymal disease.
• Male Patients: Sexually active male patients and/or their female partners are recommended to use effective contraception during treatment of the male patient and for at least 90 days after cessation of treatment ( 8.3)
OVERDOSAGE SECTION
10 OVERDOSAGE
Possible signs and symptoms of acute overdose include hematological
abnormalities such as leukopenia and neutropenia, and gastrointestinal
symptoms such as abdominal pain, diarrhea, nausea, vomiting, and dyspepsia.
The experience with overdose of mycophenolate mofetil in humans is limited.
The reported effects associated with overdose fall within the known safety
profile of the drug. The highest dose administered to kidney transplant
patients in clinical trials has been 4 g/day. In limited experience with heart
and liver transplant patients in clinical trials, the highest doses used were
4 g/day or 5 g/day. At doses of 4 g/day or 5 g/day, there appears to be a
higher rate, compared to the use of 3 g/day or less, of gastrointestinal
intolerance (nausea, vomiting, and/or diarrhea), and occasional hematologic
abnormalities, particularly neutropenia [see Warnings and Precautions (5.4)].
Treatment and Management
MPA and the phenolic glucuronide metabolite of MPA (MPAG) are usually not
removed by hemodialysis. However, at high MPAG plasma concentrations (>100
mcg/mL), small amounts of MPAG are removed. By increasing excretion of the
drug, MPA can be removed by bile acid sequestrants, such as cholestyramine
[see Clinical Pharmacology (12.3)].
DESCRIPTION SECTION
11 DESCRIPTION
Mycophenolate mofetil, USP 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, USP (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 a molecular formula of C 23H 31NO 7, a molecular weight of 433.5, and
the following structural formula:
Mycophenolate mofetil, USP is a white or almost white crystalline powder. It
is freely soluble in acetone; sparingly soluble in ethanol and slightly
soluble in water. The apparent partition coefficient in 1-octanol/water (pH
7.4) buffer solution is 238. The pKa values for mycophenolate mofetil are 5.6
for the morpholino group and 8.5 for the phenolic group.

containing 250 mg of mycophenolate mofetil, USP.
Inactive ingredients in mycophenolate mofetil capsules USP, 250 mg include
croscarmellose sodium, magnesium stearate, povidone (K-90) and pregelatinized
starch.
The capsule shells contain FD&C blue #2, gelatin, iron oxide red, iron oxide
yellow, sodium lauryl sulfate and titanium dioxide. The capsules are imprinted
with a pharmaceutical grade ink containing black iron oxide, potassium
hydroxide, propylene glycol, shellac and strong ammonia solution.
CLINICAL PHARMACOLOGY SECTION
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Mycophenolate mofetil (MMF) is absorbed following oral administration and
hydrolyzed to mycophenolic acid (MPA), the active metabolite. MPA is a
selective uncompetitive inhibitor of the two isoforms (type I and type II) of
inosine monophosphate dehydrogenase (IMPDH) leading to inhibition of the de
novopathway of guanosine nucleotide synthesis and blocks DNA synthesis. The
mechanism of action of MPA is multifaceted and includes effects on cellular
checkpoints responsible for metabolic programming of lymphocytes. MPA shifts
transcriptional activities in lymphocytes from a proliferative state to
catabolic processes. In vitrostudies suggest that MPA modulates
transcriptional activities in human CD4 +T-lymphocytes by suppressing the
Akt/mTOR and STAT5 pathways that are relevant to metabolism and survival,
leading to an anergic state of T-cells whereby the cells become less
responsive to antigenic stimulation. Additionally, MPA enhanced the expression
of negative co-stimulators such as CD70, PD-1, CTLA-4, and transcription
factor FoxP3 as well as decreased the expression of positive co-stimulators
CD27 and CD28.
MPA decreases proliferative responses of T- and B-lymphocytes to both
mitogenic and allo-antigenic stimulation, antibody responses, as well as the
production of cytokines from lymphocytes and monocytes such as GM-CSF, IFN-Ɣ,
IL-17, and TNF-α. Additionally, MPA prevents the glycosylation of lymphocyte
and monocyte glycoproteins that are involved in intercellular adhesion to
endothelial cells and may inhibit recruitment of leukocytes into sites of
inflammation and graft rejection.
Overall, the effect of MPA is cytostatic and reversible.
12.2 Pharmacodynamics
There is a lack of information regarding the pharmacodynamic effects of MMF.
12.3 Pharmacokinetics
Absorption
Following oral and intravenous administration, MMF undergoes complete
conversion to MPA, the active metabolite. In 12 healthy volunteers, the mean
absolute bioavailability of oral MMF relative to intravenous MMF was 94%. Two
500 mg mycophenolate mofetil tablets have been shown to be bioequivalent to
four 250 mg mycophenolate mofetil capsules. Five mL of the 200 mg/mL
constituted mycophenolate mofetil oral suspension have been shown to be
bioequivalent to four 250 mg capsules.
The mean (±SD) pharmacokinetic parameters estimates for MPA following the
administration of MMF given as single doses to healthy volunteers, and
multiple doses to kidney, heart, and liver transplant patients, are shown in
Table 10. The area under the plasma-concentration time curve (AUC) for MPA
appears to increase in a dose- proportional fashion in kidney transplant
patients receiving multiple oral doses of MMF up to a daily dose of 3 g (1.5 g
twice daily) (seeTable 10).

aAUC(0 to 12h) values quoted are extrapolated from data from samples collected
over 4 hours.
In the early post-transplant period (less than 40 days post-transplant),
kidney, heart, and liver transplant patients had mean MPA AUCs approximately
20% to 41% lower and mean C maxapproximately 32% to 44% lower compared to the
late transplant period (i.e., 3 to 6 months post-transplant) (non-stationarity
in MPA pharmacokinetics).
Mean MPA AUC values following administration of 1 g twice daily intravenous
mycophenolate mofetil over 2 hours to kidney transplant patients for 5 days
were about 24% higher than those observed after oral administration of a
similar dose in the immediate post-transplant phase.
In liver transplant patients, administration of 1 g twice daily intravenous
mycophenolate mofetil followed by 1.5 g twice daily oral mycophenolate mofetil
resulted in mean MPA AUC estimates similar to those found in kidney transplant
patients administered 1 g mycophenolate mofetil twice daily.
Effect of Food
Food (27 g fat, 650 calories) had no effect on the extent of absorption (MPA
AUC) of MMF when administered at doses of 1.5 g twice daily to kidney
transplant patients. However, MPA C maxwas decreased by 40% in the presence of
food [see Dosage and Administration (2.1)].
Distribution
The mean (±SD) apparent volume of distribution of MPA in 12 healthy volunteers
was approximately 3.6 (±1.5) L/kg. At clinically relevant concentrations, MPA
is 97% bound to plasma albumin. The phenolic glucuronide metabolite of MPA
(MPAG) is 82% bound to plasma albumin at MPAG concentration ranges that are
normally seen in stable kidney transplant patients; however, at higher MPAG
concentrations (observed in patients with kidney impairment or delayed kidney
graft function), the binding of MPA may be reduced as a result of competition
between MPAG and MPA for protein binding. Mean blood to plasma ratio of
radioactivity concentrations was approximately 0.6 indicating that MPA and
MPAG do not extensively distribute into the cellular fractions of blood.
In vitrostudies to evaluate the effect of other agents on the binding of MPA
to human serum albumin (HSA) or plasma proteins showed that salicylate (at 25
mg/dL with human serum albumin) and MPAG (at ≥ 460 mcg/mL with plasma
proteins) increased the free fraction of MPA. MPA at concentrations as high as
100 mcg/mL had little effect on the binding of warfarin, digoxin or
propranolol, but decreased the binding of theophylline from 53% to 45% and
phenytoin from 90% to 87%.
Elimination
Mean (±SD) apparent half-life and plasma clearance of MPA are 17.9 (±6.5)
hours and 193 (±48) mL/min following oral administration and 16.6 (±5.8) hours
and 177 (±31) mL/min following intravenous administration, respectively.
Metabolism
The parent drug, MMF, can be measured systemically during the intravenous
infusion; however, approximately 5 minutes after the infusion is stopped or
after oral administration, MMF concentrations are below the limit of
quantitation (0.4 mcg/mL).
Metabolism to MPA occurs pre-systemically after oral dosing. MPA is
metabolized principally by glucuronyl transferase to form MPAG, which is not
pharmacologically active. In vivo, MPAG is converted to MPA during
enterohepatic recirculation. The following metabolites of the 2-hydroxyethyl-
morpholino moiety are also recovered in the urine following oral
administration of MMF to healthy subjects: N-(2-carboxymethyl)-morpholine,
N-(2-hydroxyethyl)-morpholine, and the N-oxide of
N-(2-hydroxyethyl)-morpholine.
Due to the enterohepatic recirculation of MPAG/MPA, secondary peaks in the
plasma MPA concentration-time profile are usually observed 6 to 12 hours post-
dose. Bile sequestrants, such as cholestyramine, reduce MPA AUC by interfering
with this enterohepatic recirculation of the drug [see Overdosage (10) and Drug Interaction Studies below].
Excretion
Negligible amount of drug is excreted as MPA (less than 1% of dose) in the
urine. Orally administered radiolabeled MMF resulted in complete recovery of
the administered dose, with 93% of the administered dose recovered in the
urine and 6% recovered in feces. Most (about 87%) of the administered dose is
excreted in the urine as MPAG. At clinically encountered concentrations, MPA
and MPAG are usually not removed by hemodialysis. However, at high MPAG plasma
concentrations (> 100 mcg/mL), small amounts of MPAG are removed.
Increased plasma concentrations of MMF metabolites (MPA 50% increase and MPAG
about a 3-fold to 6-fold increase) are observed in patients with renal
insufficiency [see Specific Populations].
Specific Populations
Patients with Renal Impairment
The mean (±SD) pharmacokinetic parameters for MPA following the administration
of oral MMF given as single doses to non-transplant subjects with renal
impairment are presented inTable 11.
In a single-dose study, MMF was administered as a capsule or as an intravenous
infusion over 40 minutes. Plasma MPA AUC observed after oral dosing to
volunteers with severe chronic renal impairment (GFR < 25 mL/min/1.73 m 2) was
about 75% higher relative to that observed in healthy volunteers (GFR > 80
mL/min/1.73 m 2). In addition, the single-dose plasma MPAG AUC was 3-fold to
6-fold higher in volunteers with severe renal impairment than in volunteers
with mild renal impairment or healthy volunteers, consistent with the known
renal elimination of MPAG. No data are available on the safety of long-term
exposure to this level of MPAG.
Plasma MPA AUC observed after single-dose (1 g) intravenous dosing to
volunteers (n=4) with severe chronic renal impairment (GFR < 25 mL/min/1.73 m
2) was 62.4 mcg•h/mL (±19.3). Multiple dosing of MMF in patients with severe
chronic renal impairment has not been studied.
Patients with Delayed Graft Function or Nonfunction
In patients with delayed renal graft function post-transplant, mean MPA AUC(0
to 12h) was comparable to that seen in post-transplant patients without
delayed renal graft function. There is a potential for a transient increase in
the free fraction and concentration of plasma MPA in patients with delayed
renal graft function. However, dose adjustment does not appear to be necessary
in patients with delayed renal graft function. Mean plasma MPAG AUC(0 to 12h)
was 2-fold to 3-fold higher than in post-transplant patients without delayed
renal graft function [see Dosage and Administration (2.5)].
In eight patients with primary graft non-function following kidney
transplantation, plasma concentrations of MPAG accumulated about 6-fold to
8-fold after multiple dosing for 28 days. Accumulation of MPA was about 1-fold
to 2-fold.
The pharmacokinetics of MMF are not altered by hemodialysis. Hemodialysis
usually does not remove MPA or MPAG. At high concentrations of MPAG (> 100
mcg/mL), hemodialysis removes only small amounts of MPAG.
Patients with Hepatic Impairment
The mean (± SD) pharmacokinetic parameters for MPA following the
administration of oral MMF given as single doses to non-transplant subjects
with hepatic impairment is presented inTable 11.
In a single-dose (1 g oral) study of 18 volunteers with alcoholic cirrhosis
and 6 healthy volunteers, hepatic MPA glucuronidation processes appeared to be
relatively unaffected by hepatic parenchymal disease when pharmacokinetic
parameters of healthy volunteers and alcoholic cirrhosis patients within this
study were compared. However, it should be noted that for unexplained reasons,
the healthy volunteers in this study had about a 50% lower AUC as compared to
healthy volunteers in other studies, thus making comparisons between
volunteers with alcoholic cirrhosis and healthy volunteers difficult. In a
single-dose (1 g intravenous) study of 6 volunteers with severe hepatic
impairment (aminopyrine breath test less than 0.2% of dose) due to alcoholic
cirrhosis, MMF was rapidly converted to MPA. MPA AUC was 44.1 mcg•h/mL
(±15.5).

Pediatric Patients
The pharmacokinetic parameters of MPA and MPAG have been evaluated in 55
pediatric patients (ranging from 1 year to 18 years of age) receiving
mycophenolate mofetil oral suspension at a dose of 600 mg/m 2twice daily (up
to a maximum of 1 g twice daily) after allogeneic kidney transplantation. The
pharmacokinetic data for MPA is provided inTable 12.

The mycophenolate mofetil oral suspension dose of 600 mg/m 2twice daily (up to
a maximum of 1 g twice daily) achieved mean MPA AUC values in pediatric
patients similar to those seen in adult kidney transplant patients receiving
mycophenolate mofetil capsules at a dose of 1 g twice daily in the early post-
transplant period. There was wide variability in the data. As observed in
adults, early post-transplant MPA AUC values were approximately 45% to 53%
lower than those observed in the later post-transplant period (>3 months). MPA
AUC values were similar in the early and late post-transplant period across
the 1 to 18-year age range.
A comparison of dose-normalized (to 600 mg/m 2) MPA AUC values in 12 pediatric
kidney transplant patients less than 6 years of age at 9 months post-
transplant with those values in 7 pediatric liver transplant patients [median age 17 months (range: 10 to 60 months)] and at 6 months and beyond post-
transplant revealed that, at the same dose, there were on average 23% lower
AUC values in the pediatric liver compared to pediatric kidney patients. This
is consistent with the need for higher dosing in adult liver transplant
patients compared to kidney transplant patients to achieve the same exposure.
In adult transplant patients administered the same dosage of mycophenolate
mofetil, there is similar MPA exposure among kidney transplant and heart
transplant patients. Based on the established similarity in MPA exposure
between pediatric kidney transplant and adult kidney transplant patients at
their respective approved doses, it is expected that MPA exposure at the
recommended dosage will be similar in pediatric heart transplant and adult
heart transplant patients.
Male and Female Patients
Data obtained from several studies were pooled to look at any gender-related
differences in the pharmacokinetics of MPA (data were adjusted to 1 g oral
dose). Mean (±SD) MPA AUC (0 to 12h) for males (n=79) was 32.0 (±14.5) and for
females (n=41) was 36.5 (±18.8) mcg•h/mL while mean (±SD) MPA C maxwas 9.96
(±6.19) in the males and 10.6 (±5.64) mcg/mL in the females. These differences
are not of clinical significance.
Geriatric Patients
The pharmacokinetics of mycophenolate mofetil and its metabolites have not
been found to be altered in geriatric transplant patients when compared to
younger transplant patients.
Drug Interaction Studies
Acyclovir
Coadministration of MMF (1 g) and acyclovir (800 mg) to 12 healthy volunteers
resulted in no significant change in MPA AUC and C max. However, MPAG and
acyclovir plasma AUCs were increased 10.6% and 21.9%, respectively.
Antacids with Magnesium and Aluminum Hydroxides
Absorption of a single dose of MMF (2 g) was decreased when administered to 10
rheumatoid arthritis patients also taking Maalox ®TC (10 mL qid). The C maxand
AUC(0 to 24h) for MPA were 33% and 17% lower, respectively, than when MMF was
administered alone under fasting conditions.
Proton Pump Inhibitors (PPIs)
Coadministration of PPIs (e.g., lansoprazole, pantoprazole) in single doses to
healthy volunteers and multiple doses to transplant patients receiving
mycophenolate mofetil has been reported to reduce the exposure to MPA. An
approximate reduction of 30 to 70% in the C maxand 25% to 35% in the AUC of
MPA has been observed, possibly due to a decrease in MPA solubility at an
increased gastric pH.
Cholestyramine
Following single-dose administration of 1.5 g MMF to 12 healthy volunteers
pretreated with 4 g three times a day of cholestyramine for 4 days, MPA AUC
decreased approximately 40%. This decrease is consistent with interruption of
enterohepatic recirculation which may be due to binding of recirculating MPAG
with cholestyramine in the intestine.
Cyclosporine
Cyclosporine (Sandimmune ®) pharmacokinetics (at doses of 275 to 415 mg/day)
were unaffected by single and multiple doses of 1.5 g twice daily of MMF in 10
stable kidney transplant patients. The mean (±SD) AUC(0 to 12h) and C maxof
cyclosporine after 14 days of multiple doses of MMF were 3290 (±822) ng•h/mL
and 753 (±161) ng/mL, respectively, compared to 3245 (±1088) ng•h/mL and 700
(±246) ng/mL, respectively, 1 week before administration of MMF.
Cyclosporine A interferes with MPA enterohepatic recirculation. In kidney
transplant patients, mean MPA exposure (AUC(0 to 12h)) was approximately 30 to
50% greater when MMF was administered without cyclosporine compared with when
MMF was coadministered with cyclosporine. This interaction is due to
cyclosporine inhibition of multidrug-resistance-associated protein 2 (MRP-2)
transporter in the biliary tract, thereby preventing the excretion of MPAG
into the bile that would lead to enterohepatic recirculation of MPA. This
information should be taken into consideration when MMF is used without
cyclosporine.
Drugs Affecting Glucuronidation
Concomitant administration of drugs inhibiting glucuronidation of MPA may
increase MPA exposure (e.g., increase of MPA AUC (0 to ∞) by 35% was observed
with concomitant administration of isavuconazole).
Concomitant administration of telmisartan and mycophenolate mofetil resulted
in an approximately 30% decrease in MPA concentrations. Telmisartan changes
MPA’s elimination by enhancing PPAR gamma (peroxisome proliferator- activated
receptor gamma) expression, which in turn results in an enhanced UGT1A9
expression and glucuronidation activity.
Ganciclovir
Following single-dose administration to 12 stable kidney transplant patients,
no pharmacokinetic interaction was observed between MMF (1.5 g) and
intravenous ganciclovir (5 mg/kg). Mean (±SD) ganciclovir AUC and C max(n=10)
were 54.3 (±19.0) mcg•h/mL and 11.5 (±1.8) mcg/mL, respectively, after
coadministration of the two drugs, compared to 51.0 (±17.0) mcg•h/mL and 10.6
(±2.0) mcg/mL, respectively, after administration of intravenous ganciclovir
alone. The mean (±SD) AUC and C maxof MPA (n=12) after coadministration were
80.9 (±21.6) mcg•h/mL and 27.8 (±13.9) mcg/mL, respectively, compared to
values of 80.3 (±16.4) mcg•h/mL and 30.9 (±11.2) mcg/mL, respectively, after
administration of MMF alone.
Oral Contraceptives
A study of coadministration of mycophenolate mofetil (1 g twice daily) and
combined oral contraceptives containing ethinylestradiol (0.02 mg to 0.04 mg)
and levonorgestrel (0.05 mg to 0.20 mg), desogestrel (0.15 mg) or gestodene
(0.05 mg to 0.10 mg) was conducted in 18 women with psoriasis over 3
consecutive menstrual cycles. Mean serum levels of LH, FSH and progesterone
were not significantly affected. Mean AUC(0 to 24h) was similar for
ethinylestradiol and 3-keto desogestrel; however, mean levonorgestrel AUC(0 to
24h) significantly decreased by about 15%. There was large inter-patient
variability (%CV in the range of 60% to 70%) in the data, especially for
ethinylestradiol.
Sevelamer
Concomitant administration of sevelamer and MMF in adult and pediatric
patients decreased the mean MPA C maxand AUC (0 to 12h) by 36% and 26%
respectively.
Antimicrobials
Antimicrobials eliminating beta-glucuronidase-producing bacteria in the
intestine (e.g. aminoglycoside, cephalosporin, fluoroquinolone, and penicillin
classes of antimicrobials) may interfere with the MPAG/MPA enterohepatic
recirculation thus leading to reduced systemic MPA exposure. Information
concerning antibiotics is as follows:
• Trimethoprim/Sulfamethoxazole: Following single-dose administration of MMF
(1.5 g) to 12 healthy male volunteers on day 8 of a 10-day course of
trimethoprim 160 mg/sulfamethoxazole 800 mg administered twice daily, no
effect on the bioavailability of MPA was observed. The mean (±SD) AUC and C
maxof MPA after concomitant administration were 75.2 (±19.8) mcg•h/mL and 34.0
(±6.6) mcg/mL, respectively, compared to 79.2 (±27.9) mcg•h/mL and 34.2
(±10.7) mcg/mL, respectively, after administration of MMF alone.
• Norfloxacin and Metronidazole: Following single-dose administration of MMF
(1 g) to 11 healthy volunteers on day 4 of a 5-day course of a combination of
norfloxacin and metronidazole, the mean MPA AUC(0 to 48h) was significantly
reduced by 33% compared to the administration of MMF alone (p<0.05). The mean
(±SD) MPA AUC(0 to 48h) after coadministration of MMF with norfloxacin or
metronidazole separately was 48.3 (±24) mcg·h/mL and 42.7 (±23) mcg·h/mL,
respectively, compared with 56.2 (±24) mcg·h/mL after administration of MMF
alone.
• Ciprofloxacin and Amoxicillin Plus Clavulanic Acid: A total of 64
mycophenolate mofetil -treated kidney transplant recipients received either
oral ciprofloxacin 500 mg twice daily or amoxicillin plus clavulanic acid 375
mg three times daily for 7 or at least 14 days, respectively. Approximately
50% reductions in median trough MPA concentrations (pre-dose) from baseline
(mycophenolate mofetil alone) were observed in 3 days following commencement
of oral ciprofloxacin or amoxicillin plus clavulanic acid. These reductions in
trough MPA concentrations tended to diminish within 14 days of antimicrobial
therapy and ceased within 3 days of discontinuation of antibiotics.
• Rifampin: In a single heart-lung transplant patient, after correction for
dose, a 67% decrease in MPA exposure (AUC(0 to 12h)) has been observed with
concomitant administration of MMF and rifampin.
NONCLINICAL TOXICOLOGY SECTION
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
In a 104-week oral carcinogenicity study in mice, MMF in daily doses up to 180
mg/kg was not tumorigenic. The highest dose tested was 0.2 times the
recommended clinical dose (2 g/day) in renal transplant patients and 0.15
times the recommended clinical dose (3 g/day) in cardiac transplant patients
when corrected for differences in body surface area (BSA). In a 104-week oral
carcinogenicity study in rats, MMF in daily doses up to 15 mg/kg was not
tumorigenic. The highest dose was 0.035 times the recommended clinical dose in
kidney transplant patients and 0.025 times the recommended clinical dose in
heart transplant patients when corrected for BSA. While these animal doses
were lower than those given to patients, they were maximal in those species
and were considered adequate to evaluate the potential for human risk [see Warnings and Precautions (5.2)].
The genotoxic potential of MMF was determined in five assays. MMF was
genotoxic in the mouse lymphoma/thymidine kinase assay and the in vivomouse
micronucleus assay. MMF was not genotoxic in the bacterial mutation assay, the
yeast mitotic gene conversion assay or the Chinese hamster ovary cell
chromosomal aberration assay.
MMF had no effect on fertility of male rats at oral doses up to 20 mg/kg/day.
This dose represents 0.05 times the recommended clinical dose in renal
transplant patients and 0.03 times the recommended clinical dose in cardiac
transplant patients when corrected for BSA. In a female fertility and
reproduction study conducted in rats, oral doses of 4.5 mg/kg/day caused
malformations (principally of the head and eyes) in the first generation
offspring in the absence of maternal toxicity. This dose was 0.01 times the
recommended clinical dose in renal transplant patients and 0.005 times the
recommended clinical dose in cardiac transplant patients when corrected for
BSA. No effects on fertility or reproductive parameters were evident in the
dams or in the subsequent generation.
CLINICAL STUDIES SECTION
14 CLINICAL STUDIES
14.1 Kidney Transplantation
Adults
The three de novokidney transplantation studies 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) to prevent acute rejection
episodes. One of the two studies with azathioprine (AZA) control arm also
included anti-thymocyte globulin (ATGAM ®) induction therapy. The geographic
location of the investigational sites of these studies are included inTable
13.
In all three de novokidney transplantation studies, the primary efficacy
endpoint was the proportion of patients in each treatment group who
experienced treatment failure within the first 6 months after transplantation.
Treatment failure was defined as biopsy-proven acute rejection on treatment or
the occurrence of death, graft loss or early termination from the study for
any reason without prior biopsy-proven rejection.
Mycophenolate mofetil, in combination with corticosteroids and cyclosporine,
reduced (statistically significant at 0.05 level) the incidence of treatment
failure within the first 6 months following transplantation (Table 13).
Patients who prematurely discontinued treatment were followed for the
occurrence of death or graft loss, and the cumulative incidence of graft loss
and patient death combined are summarized inTable 14. Patients who
prematurely discontinued treatment were not followed for the occurrence of
acute rejection after termination.

better outcome than controls in all three studies; patients receiving
mycophenolate mofetil 2 g/day experienced a better outcome than mycophenolate
mofetil 3 g/day in two of the three studies. Patients in all treatment groups
who terminated treatment early were found to have a poor outcome with respect
to graft loss or patient death at 1 year.

Pediatrics- De Novo Kidney transplantation PK Study with Long Term Follow-Up
One open-label, safety and pharmacokinetic study of mycophenolate mofetil oral suspension 600 mg/m 2twice daily (up to 1 g twice daily) in combination with cyclosporine and corticosteroids was performed at centers in the United States (9), Europe (5) and Australia (1) in 100 pediatric patients (3 months to 18 years of age) for the prevention of renal allograft rejection. Mycophenolate mofetil was well tolerated in pediatric patients [see Adverse Reactions (6.1)], and the pharmacokinetics profile was similar to that seen in adult patients dosed with 1 g twice daily mycophenolate mofetil capsules [see Clinical Pharmacology (12.3)]. The rate of biopsy-proven rejection was similar across the age groups (3 months to <6 years, 6 years to <12 years, 12 years to 18 years). The overall biopsy-proven rejection rate at 6 months was comparable to adults. The combined incidence of graft loss (5%) and patient death (2%) at 12 months post-transplant was similar to that observed in adult kidney transplant patients.
14.2 Heart Transplantation
A double-blind, randomized, comparative, parallel-group, multicenter study in
primary de novoheart transplant recipients was performed at centers in the
United States (20), in Canada (1), in Europe (5) and in Australia (2). The
total number of patients enrolled (ITT population) was 650; 72 never received
study drug and 578 received study drug (Safety Population). Patients received
mycophenolate mofetil 1.5 g twice daily (n=289) or AZA 1.5 to 3 mg/kg/day
(n=289), in combination with cyclosporine (Sandimmune ®or Neoral ®) and
corticosteroids as maintenance immunosuppressive therapy. The two primary
efficacy endpoints were: (1) the proportion of patients who, after
transplantation, had at least one endomyocardial biopsy-proven rejection with
hemodynamic compromise, or were re-transplanted or died, within the first 6
months, and (2) the proportion of patients who died or were re-transplanted
during the first 12 months following transplantation. Patients who prematurely
discontinued treatment were followed for the occurrence of allograft rejection
for up to 6 months and for the occurrence of death for 1 year.
The analyses of the endpoints showed:
• Rejection: No difference was established between mycophenolate mofetil and
AZA with respect to biopsy-proven rejection with hemodynamic compromise.
• Survival: mycophenolate mofetil was shown to be at least as effective as AZA
in preventing death or re-transplantation at 1 year (seeTable 15).

14.3 Liver Transplantation
A double-blind, randomized, comparative, parallel-group, multicenter study in
primary hepatic transplant recipients was performed at centers in the United
States (16), in Canada (2), in Europe (4) and in Australia (1). The total
number of patients enrolled was 565. Per protocol, 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 AZA 1 to 2 mg/kg/day
intravenously followed by AZA 1 to 2 mg/kg/day orally, in combination with
cyclosporine (Neoral ®) and corticosteroids as maintenance immunosuppressive
therapy. The actual median oral dose of AZA on study was 1.5 mg/kg/day (range
of 0.3 to 3.8 mg/kg/day) initially and 1.26 mg/kg/day (range of 0.3 to 3.8
mg/kg/day) at 12 months. The two primary endpoints were: (1) the proportion of
patients who experienced, in the first 6 months post-transplantation, one or
more episodes of biopsy-proven and treated rejection or death or re-
transplantation, and (2) the proportion of patients who experienced graft loss
(death or re-transplantation) during the first 12 months post-transplantation.
Patients who prematurely discontinued treatment were followed for the
occurrence of allograft rejection and for the occurrence of graft loss (death
or re-transplantation) for 1 year.
In combination with corticosteroids and cyclosporine, mycophenolate mofetil
demonstrated a lower rate of acute rejection at 6 months and a similar rate of
death or re-transplantation at 1 year compared to AZA (Table 16).

INFORMATION FOR PATIENTS SECTION
17 PATIENT COUNSELING INFORMATION
Advise the patient to read the FDA-approved patient labeling (Medication Guide and Instructions for Use).
17.1 Embryofetal Toxicity
Pregnancy loss and malformations
• Inform females of reproductive potential and pregnant women that use of
mycophenolate mofetil during pregnancy is associated with an increased risk of
first trimester pregnancy loss and an increased risk of congenital
malformations. Advise that they must use an acceptable form of contraception
[see Warnings and Precautions (5.1), Use in Specific Populations (8.1, 8.3)].
• Encourage pregnant women to enroll in the Pregnancy Exposure Registry. This
registry monitors pregnancy outcomes in women exposed to mycophenolate [see Use in Specific Populations (8.1)].
Contraception
• Discuss pregnancy testing, pregnancy prevention and planning with females of
reproductive potential [see Use in Specific Populations (8.3)].
• Females of reproductive potential must use an acceptable form of birth
control during the entire mycophenolate mofetil therapy and for 6 weeks after
stopping mycophenolate mofetil, unless the patient chooses abstinence.
Mycophenolate mofetil may reduce effectiveness of oral contraceptives. Use of
additional barrier contraceptive methods is recommended [see Use in Specific Populations (8.3)].
• For patients who are considering pregnancy, discuss appropriate alternative
immunosuppressants with less potential for embryofetal toxicity. Risks and
benefits of mycophenolate mofetil should be discussed with the patient.
• Advise sexually active male patients and/or their partners to use effective
contraception during the treatment of the male patient and for at least 90
days after cessation of treatment. This recommendation is based on findings of
animal studies [see Use in Specific Populations (8.3), Nonclinical Toxicology (13.1)].
17.2 Development of Lymphoma and Other Malignancies
• Inform patients that they are at increased risk of developing lymphomas and
other malignancies, particularly of the skin, due to immunosuppression [see Warnings and Precautions (5.2)].
• Advise patients to limit exposure to sunlight and ultraviolet (UV) light by
wearing protective clothing and use of broad-spectrum sunscreen with high
protection factor.
17.3 Increased Risk of Serious Infections
Inform patients that they are at increased risk of developing a variety of infections due to immunosuppression. Instruct them to contact their physician if they develop any of the signs and symptoms of infection explained in the Medication Guide [see Warnings and Precautions (5.3)].
17.4 Blood Dyscrasias
Inform patients that they are at increased risk for developing blood adverse effects such as anemia or low white blood cells. Advise patients to immediately contact their healthcare provider if they experience any evidence of infection, unexpected bruising, or bleeding, or any other manifestation of bone marrow suppression [see Warnings and Precautions (5.4)].
17.5 Gastrointestinal Tract Complications
Inform patients that mycophenolate mofetil can cause gastrointestinal tract complications including bleeding, intestinal perforations, and gastric or duodenal ulcers. Advise the patient to contact their healthcare provider if they have symptoms of gastrointestinal bleeding, or sudden onset or persistent abdominal pain [see Warnings and Precautions (5.5)].
17.6 Acute Inflammatory Syndrome
Inform patients that acute inflammatory reactions have been reported in some patients who received mycophenolate mofetil. Some reactions were severe, requiring hospitalization. Advise patients to contact their physician if they develop fever, joint stiffness, joint pain or muscle pains [see Warnings and Precautions (5.7)].
17.7 Hypersensitivity Reactions
Inform patients of the potential risk of hypersensitivity reactions. Advise patients to stop taking mycophenolate mofetil and seek immediate medical attention if signs or symptoms of hypersensitivity reaction occur (such as swelling of face, lips, tongue, or throat; difficulty breathing or swallowing) [see Warnings and Precautions ( 5.8)].
17.8 Immunizations
Inform patients that mycophenolate mofetil can interfere with the usual response to immunizations. Before seeking vaccines on their own, advise patients to discuss first with their physician [see Warnings and Precautions (5.9)].
17.9 Administration Instructions
• Advise patients not to open mycophenolate mofetil capsules.
• Advise patients to avoid inhalation or contact of the skin or mucous
membranes with the powder contained in mycophenolate mofetil capsules. If such
contact occurs, they must wash the area of contact thoroughly with soap and
water. In case of ocular contact, rinse eyes with plain water.
• Advise patients to take a missed dose as soon as they remember, except if it
is closer than 2 hours to the next scheduled dose; in this case they should
continue to take mycophenolate mofetil capsules at the usual times.
17.10 Blood Donation
Advise patients not to donate blood during therapy and for at least 6 weeks following discontinuation of mycophenolate mofetil [see Warnings and Precautions (5.12)].
17.11 Semen Donation
Advise males of childbearing potential not to donate semen during therapy and for 90 days following discontinuation of mycophenolate mofetil [see Warnings and Precautions (5.13)].
17.12 Potential to Impair Driving and Use of Machinery
Advise patients that mycophenolate mofetil can affect the ability to drive or operate machines.
