Prograf
Prograf ( tacrolimus )
capsules
Prograf ( tacrolimus )
injection (for intravenous infusion only)
WARNING
Increased
susceptibility to infection and the possible development of lymphoma may result
from
immunosuppression.
Only physicians experienced in immunosuppressive therapy and
management
of organ transplant patients should prescribe Prograf. Patients receiving the
drug
should
be managed in facilities equipped and staffed with adequate laboratory and
supportive
medical
resources. The physician responsible for maintenance therapy should have
complete
information
requisite for the follow-up of the patient.

USP, 80.0% v/v. Prograf injection must be diluted with 0.9% Sodium Chloride
Injection
or
5% Dextrose Injection before use.
Prograf (
Prograf ( tacrolimus ) ),
previously known as FK506, is the active ingredient in Prograf. Prograf ( Prograf ( tacrolimus )
) is
a
macrolide immunosuppressant produced by Streptomyces tsukubaensis.
Chemically,
Prograf ( Prograf ( tacrolimus ) ) is designated as [3S-[3R*[E(1S*,3S*,4S*)],
4S*,5R*,8S*,9E,12R*,14R*,15S*,16R*,18S*,19S*,26aR*]]-
5,6,8,11,12,13,14,15,16,17,18,19,24,25,26,26a-hexadecahydro-5,19-dihydroxy-3-[2-(4-hydroxy-
3-methoxycyclohexyl)-1-methylethenyl]-14,16-dimethoxy-4,10,12,18-tetramethyl-8-(2-propenyl)-
15,19-epoxy-3H-pyrido[2,1-c][1,4]
oxaazacyclotricosine-1,7,20,21(4H,23H)-tetrone, monohydrate.
The
chemical structure of Prograf ( Prograf ( tacrolimus ) ) is:
Prograf (
Prograf ( tacrolimus ) )
has an empirical formula of C44H69NO12•H2O
and a formula weight of 822.03.
Tacroliums
appears as white crystals or crystalline powder. It is practically insoluble in
water,
freely
soluble in ethanol, and very soluble in methanol and chloroform.
CLINICAL
PHARMACOLOGY:
Mechanism of Action
Prograf (
Prograf ( tacrolimus ) )
prolongs the survival of the host and transplanted graft in animal transplant
models of
liver,
kidney, heart, bone marrow, small bowel and pancreas, lung and trachea, skin,
cornea, and
limb.
In
animals, Prograf ( Prograf ( tacrolimus ) ) has been demonstated to suppress
some humoral immunity and,
to
a greater extent, cell-mediated reactions such as allograft rejection, delayed
type
hypersensitivity,
collagen-induced arthritis, experimental allergic encephalomyelitits, and graft
versus
host disease.
Prograf (
Prograf ( tacrolimus ) )
inhibits T-lymphocyte activation, although the exact mechanism of action is
not
known. Experimental evidence suggests that Prograf ( tacrolimus ) binds to an
intracellular protein,
FKBP-12.
A complex of Prograf ( tacrolimus )-FKBP-12, calcium, calmodulin, and
calcineurin is then formed
and
the phosphatase activity of calcineurin inhibited. This effect may prevent the
dephosphorylation
and translocation of nuclear factor of activated T-cells (NF-AT), a nuclear
component
thought to initiate gene transcription for the formation of lymphokines (such as
interleukin-2,
gamma interferon). The net result is the inhibition of T-lymphocyte activation
(i.e.,
immunosuppression).
Due
to intersubject variability in Prograf ( tacrolimus ) pharmacokinetics,
individualization of dosing regimen
is
necessary for optimal therapy. (See DOSAGE AND ADMINISTRATION).
Pharmacokinetic
data
indicate that whole blood concentrations rather than plasma concentrations serve
as the
more
appropriate sampling compartment to describe Prograf ( tacrolimus )
pharmacokinetics.
Absorption
Absorption
of Prograf ( tacrolimus ) from the gastrointestinal tract after oral
administration is incomplete and
variable.
The absolute bioavailablility of Prograf ( tacrolimus ) was 17±10% in adult
kidney transplant
patients
(N=26), 22±6% in adult liver transplant patients (N=17), and 18±5% in healthy
volunteers
(N=16).
A
single dose study conducted in 32 healthy volunteers established the
bioequivalence of
the
1 mg and 5 mg capsules. Another single dose study in 32 healthy volunteers
established the
bioequivalence
of the 0.5 mg and 1 mg capsules. Tacroliums maximum blood concentration
(Cmax) and area under the curve (AUC) appeared to increase in a
dose-proportional fashion in 18
fasted
healthy volunteers receiving a single oral dose of 3, 7, and 10 mg.
In
18 kidney transplant patients, Prograf ( tacrolimus ) trough concentrations from
3 to 30 ng/mL
measured
at 10-12 hours post-dose (Cmin) correlated well with the AUC (correlation
coefficient
0.93).
In 24 liver transplant patients over a concentration range of 10 to 60 ng/mL,
the correlation
coefficient
was 0.94.
Food
Effects: The rate
and extent of Prograf ( tacrolimus ) absorption were greatest under fasted
conditions.
The presence and composition of food decreased both the rate and extent of
Prograf ( tacrolimus )
absorption when administered to 15 healthy volunteers.
The
effect was most pronounced with a high-fat meal (848 kcal, 46% fat): mean AUC
and
Cmax were
decreased 37% and 77%, respectively; Tmax was
lengthened 5-fold. A highcarbohydrate
meal
(668 kcal, 85% carbohydrate) decreased mean AUC and mean Cmax by 28%
and
65%, respectively.
In
healthy volunteers (N=16), the time of the meal also affected Prograf ( tacrolimus )
bioavailability.
When
given immediately following the meal, mean Cmax
was reduced 71%, and
mean AUC was
reduced
39%, relative to the fasted condition. When administered 1.5 hours following the
meal,
mean
Cmax was reduced 63%, and mean AUC was reduced 39%, relative to the fasted
condition.
In
11 liver transplant patients, Prograf administered 15 minutes after a high fat
(400 kcal,
34%
fat) breakfast, resulted in decreased AUC (27±18%) and Cmax (50±19%), as
compared to a
fasted
state.
Distribution
The
plasma protein binding of Prograf ( tacrolimus ) is approximately 99% and is
independent of
concentration
over a range of 5-50 ng/mL. Prograf ( tacrolimus ) is bound mainly to albumin
and alpha-1-
acid
glycoprotein, and has a high level of association with erythrocytes. The
distribution of
Prograf ( tacrolimus )
between whole blood and plasma depends on several factors, such as hematocrit,
temperature
at the time of plasma separation, drug concentration, and plasma protein
concentration.
In a U.S. study, the ratio of whole blood concentration to plasma concentration
averaged
35 (range 12 to 67).
Metabolism
Prograf ( tacrolimus )
is extensively metabolized by the mixed-function oxidase system, primarily the
cytochrome
P-450 system (CYP3A). A metabolic pathway leading to the formation of 8 possible
metabolites
has been proposed. Demethylation and hydroxylation were identified as the
primary
mechanisms
of biotransformation in vitro. The major metabolite identified in incubations
with
human
liver microsomes is 13-demethyl Prograf ( tacrolimus ). In in vitro studies, a
31-demethyl metabolite
has
been reported to have the same activity as Prograf ( tacrolimus ).
Excretion
The
mean clearance following IV administration of Prograf ( tacrolimus ) is 0.040,
0.083 and 0.053 L/hr/kg in
healthy
volunteers, adult kidney transplant patients and adult liver transplant
patients,
respectively.
In man, less than 1% of the dose administered is excreted unchanged in urine.
In
a mass balance study of IV administered radiolabeled Prograf ( tacrolimus ) to 6
healthy
volunteers,
the mean recovery of radiolabel was 77.8±12.7%. Fecal elimination accounted for
92.4±1.0%
and the elimination half-life based on radioactivity was 48.1±15.9 hours
whereas it
was
43.5±11.6 hours based on Prograf ( tacrolimus ) concentrations. The mean
clearance of radiolabel was
0.029±0.015
L/hr/kg and clearance of Prograf ( tacrolimus ) was 0.029±0.009 L/hr/kg. When
administered
PO,
the mean recovery of the radiolabel was 94.9±30.7%. Fecal elimination accounted
for
92.6±30.7%,
urinary elimination accounted for 2.3±1.1% and the elimination half-life based
on
radioactivity
was 31.9±10.5 hours whereas it was 48.4±12.3 hours based on Prograf ( tacrolimus )
concentrations.
The mean clearance of radiolabel was 0.226±0.116 L/hr/kg and clearance of
Prograf ( tacrolimus )
0.172±0.088 L/hr/kg.
Special
Populations
Pediatric
Pharmacokinetics
of Prograf ( tacrolimus ) have been studied in liver transplantation patients,
0.7 to 13.2
years
of age. Following IV administration of a 0.037 mg/kg/day dose to 12 pediatric
patients,
mean
terminal half-life, volume of distribution and clearance were 11.5±3.8 hours,
2.6±2.1 L/kg
and
0.138±0.071 L/hr/kg, respectively. Following oral administration to 9 patients,
mean AUC
and
Cmax were 337±167 ng·hr/mL and 43.4±27.9 ng/mL, respectively. The absolute
bioavailability
was
31±21%.
Whole
blood trough concentrations from 31 patients less than 12 years old showed that
pediatric
patients needed higher doses than adults to achieve similar Prograf ( tacrolimus )
trough
concentrations.
(See DOSAGE
AND ADMINISTRATION).
Renal
and Hepatic Insufficiency
Prograf ( tacrolimus )
pharmacokinetics following a single IV administration were determined in 12
patients
(7 not on dialysis and 5 on dialysis, serum creatinine of 3.9±1.6 and 12.0±2.4
mg/dL,
respectively)
prior to their kidney transplant. The pharmacokinetic parameters obtained were
similar
for both groups.
The
mean clearance of Prograf ( tacrolimus ) in patients with renal dysfunction was
similar to that in
normal
volunteers (see previous table).
Hepatic
Insufficiency:
Prograf ( tacrolimus )
pharmacokinetics have been determined in six patients with mild hepatic
dysfunction
(mean Pugh score: 6.2) following single IV and oral administrations. The mean
clearance
of Prograf ( tacrolimus ) in patients with mild hepatic dysfunction was not
substantially
different
from that in normal volunteers (see previous table). Prograf ( tacrolimus )
pharmacokinetics
were
studied in 6 patients with severe hepatic dysfunction (mean Pugh score: >10).
The
mean
clearance was substantially lower in patients with severe hepatic dysfunction,
irrespective
of the route of administration.
Race
A
formal study to evaluate the pharmacokinetic disposition of Prograf ( tacrolimus )
in Black transplant
patients
has not been conducted. However, a retrospective comparison of Black and
Caucasian
kidney transplant patients indicated that Black patients required higher Prograf ( tacrolimus )
doses
to attain similar trough concentrations. (See DOSAGE AND ADMINISTRATION.)
Gender
A
formal study to evaluate the effect of gender on Prograf ( tacrolimus )
pharmacokinetics has not been
conducted,
however, there was no difference in dosing by gender in the kidney transplant
trial.
A retrospective comparison of pharmacokinetics in healthy volunteers, and in
kidney
and
liver transplant patients indicated no gender-based differences.
Clinical Studies
Liver Transplantation
The
safety and efficacy of Prograf-based immunosuppression following orthotopic
liver
transplantation
were assessed in two prospective, randomized, non-blinded multicenter
studies.
The active control groups were treated with a cyclosporine-based
immunosuppressive
regimen. Both studies used concomitant adrenal corticosteroids as part
of
the immunosuppressive regimens. These studies were designed to evaluate whether
the
two
regimens were therapeutically equivalent, with patient and graft survival at 12
months
following
transplantation as the primary endpoints. The Prograf-based immunosuppressive
regimen
was found to be equivalent to the cyclosporine-based immunosuppressive regimens.
In
one trial, 529 patients were enrolled at 12 clinical sites in the United States;
prior to
surgery,
263 were randomized to the Prograf-based immunosuppressive regimen and 266 to
a
cyclosporine-based immunosuppressive regimen (CBIR). In 10 of the 12 sites, the
same
CBIR
protocol was used, while 2 sites used different control protocols. This trial
excluded
patients
with renal dysfunction, fulminant hepatic failure with Stage IV encephalopathy,
and
cancers;
pediatric patients (≤ 12 years old) were allowed.
In
the second trial, 545 patients were enrolled at 8 clinical sites in Europe;
prior to
surgery,
270 were randomized to the Prograf-based immunosuppressive regimen and 275 to
CBIR.
In this study, each center used its local standard CBIR protocol in the
active-control
arm.
This trial excluded pediatric patients, but did allow enrollment of subjects
with renal
dysfunction,
fulminant hepatic failure in Stage IV encephopathy, and cancers other than
primary
hepatic with metastases.
One-year
patient survival and graft survival in the Prograf-based treatment groups were
equivalent
to those in the CBIR treatment groups in both studies. The overall one-year
patient
survival (CBIR and Prograf-based treatment groups combined) was 88% in the U.S.
study
and 78% in the European study.
The
overall one-year graft survival (CBIR and Prograf-based treatment groups
combined)
was
81% in the U.S. study and 73% in the European study. In both studies, the median
time
to
convert from IV to oral Prograf dosing was 2 days.
Because
of the nature of the study design, comparisons of differences in secondary
endpoints,
such as incidence of acute rejection, refractory rejection or use of OKT3 for
steroid-resistant
rejection, could not be reliably made.
Kidney Transplantation
Prograf-based
immunosuppression following kidney transplantation was assessed in a Phase
III
randomized, multicenter, non-blinded, prospective study. There were 412 kidney
transplant
patients enrolled at 19 clinical sites in the United States. Study therapy was
initiated
when renal function was stable as indicated by a serum creatinine ≤ 4 mg/dL
(median
of 4 days after transplantation, range 1 to 14 days). Patients less than 6 years
of
age
were excluded.
There
were 205 patients randomized to Prograf-based immunosuppression and 207
patients
were randomized to cyclosporine-based immunosuppression. All patients received
prophylactic
induction therapy consisting of an antilymphocyte antibody preparation,
corticosteroids
and azathioprine.
Overall
one year patient and graft survival was 96.1% and 89.6%, respectively and was
equivalent
between treatment arms.
Because
of the nature of the study design, comparisons of differences in secondary
endpoints,
such as incidence of acute rejection, refractory rejection or use of OKT3 for
steroid-resistant
rejection, could not be reliably made.
INDICATIONS
AND USAGE:
Prograf
is indicated for the prophylaxis of organ rejection in patients receiving
allogeneic liver
or
kidney transplants. It is recommended that Prograf be used concomitantly with
adrenal
corticosteroids.
Because of the risk of anaphylaxis, Prograf injection should be reserved for
patients
unable to take Prograf capsules orally.
CONTRAINDICATIONS:
Prograf
is contraindicated in patients with a hypersensitivity to Prograf ( tacrolimus ).
Prograf injection is
contraindicated
in patients with a hypersensitivity to HCO-60 (polyoxyl 60 hydrogenated
castor
oil).
WARNINGS:
(See
boxed WARNING.)
Insulin-dependent
post-transplant diabetes mellitus (PTDM) was reported in 20% of Prograftreated
kidney
transplant patients without pretransplant history of diabetes mellitus in the
Phase
III study (See Tables Below). The median time to onset of PTDM was 68 days.
Insulin
dependence was reversible in 15% of these PTDM patients at one year and in 50%
at
two
years post transplant. Black and Hispanic kidney transplant patients were at an
increased
risk of development of PTDM.
Incidence
of Post Transplant Diabetes Mellitus and Insulin Use at 2 Years in
Kidney
Transplant Recipients in the Phase III Study
*
use of insulin for 30 or more consecutive days, with <
5
day gap, without a prior history of
insulin
dependent diabetes mellitus or non insulin dependent diabetes mellitus.
**Patients
without pretransplant history of diabetes mellitus.
Prograf
can cause neurotoxicity and nephrotoxicity, particularly when used in high
doses.
Nephrotoxicity
was reported in approximately 52% of kidney transplantation patients and in
40%
and 36% of liver transplantation patients receiving Prograf in the U.S. and
European
randomized
trials, respectively (see ADVERSE REACTIONS). More overt nephrotoxicity is
seen
early after transplantation, characterized by increasing serum creatinine and a
decrease
in
urine output. Patients with impaired renal function should be monitored closely
as the
dosage
of Prograf may need to be reduced. In patients with persistent elevations of
serum
creatinine
who are unresponsive to dosage adjustments, consideration should be given to
changing
to another immunosuppressive therapy. Care should be taken in using Prograf ( tacrolimus )
with
other nephrotoxic drugs. In
particular, to avoid excess nephrotoxicity, Prograf
should
not be used simultaneously with cyclosporine. Prograf or cyclosporine should
be
discontinued at least 24 hours prior to initiating the other. In the presence of
elevated
Prograf or cyclosporine concentrations, dosing with the other drug usually
should
be further delayed.
Mild
to severe hyperkalemia was reported in 31% of kidney transplant recipients and
in
45%
and 13% of liver transplant recipients treated with Prograf in the U.S. and
European
randomized
trials, respectively, and may require treatment (see ADVERSE REACTIONS).
Serum
potassium levels should be monitored and potassium-sparing diuretics should
not
be used during Prograf therapy (see PRECAUTIONS).
Neurotoxicity,
including tremor, headache, and other changes in motor function, mental
status,
and sensory function were reported in approximately 55% of liver transplant
recipients
in
the two randomized studies. Tremor occurred more often in Prograf-treated kidney
transplant
patients (54%) compared to cyclosporine-treated patients. The incidence of other
neurological
events in kidney transplant patients was similar in the two treatment groups
(see
ADVERSE
REACTIONS). Tremor
and headache have been associated with high wholeblood
concentrations
of Prograf ( tacrolimus ) and may respond to dosage adjustment. Seizures have
occurred
in adult and pediatric patients receiving Prograf (see ADVERSE
REACTIONS).
Coma
and delirium also have been associated with high plasma concentrations of Prograf ( tacrolimus ).
As
in patients receiving other immunosuppressants, patients receiving Prograf are
at
increased
risk of developing lymphomas and other malignancies, particularly of the skin.
The
risk
appears to be related to the intensity and duration of immunosuppression rather
than to
the
use of any specific agent. A lymphoproliferative disorder (LPD) related to
Epstein-Barr
Virus
(EBV) infection has been reported in immunosuppressed organ transplant
recipients.
The
risk of LPD appears greatest in young children who are at risk for primary EBV
infection
while
immunosuppressed or who are switched to Prograf following long-term
immunosuppression
therapy. Because of the danger of oversuppression of the immune
system
which can increase susceptibility to infection, combination immunosuppressant
therapy
should be used with caution.
A
few patients receiving Prograf injection have experienced anaphylactic
reactions.
Although
the exact cause of these reactions is not known, other drugs with castor oil
derivatives
in the formulation have been associated with anaphylaxis in a small percentage
of
patients.
Because of this potential risk of anaphylaxis, Prograf injection should be
reserved
for
patients who are unable to take Prograf capsules.
Patients
receiving Prograf injection should be under continuous observation for at
least
the first 30 minutes following the start of the infusion and at frequent
intervals
thereafter.
If signs or symptoms of anaphylaxis occur, the infusion should be stopped.
An
aqueous solution of epinephrine should be available at the bedside as well as a
source
of oxygen.
PRECAUTIONS:
General
Hypertension
is a common adverse effect of Prograf therapy (see ADVERSE
REACTIONS).
Mild
or moderate hypertension is more frequently reported than severe hypertension.
Antihypertensive
therapy may be required; the control of blood pressure can be
accomplished
with any of the common antihypertensive agents. Since Prograf ( tacrolimus ) may
cause
hyperkalemia,
potassium-sparing diuretics should be avoided. While calcium-channel
blocking
agents can be effective in treating Prograf-associated hypertension, care should
be
taken
since interference with Prograf ( tacrolimus ) metabolism may require a dosage
reduction (see
Drug Interactions).
Renally and Hepatically Impaired Patients
For
patients with renal insufficiency some evidence suggests that lower doses should
be
used
(see CLINICAL
PHARMACOLOGY and DOSAGE
AND ADMINISTRATION).
The
use of Prograf in liver transplant recipients experiencing post-transplant
hepatic
impairment
may be associated with increased risk of developing renal insufficiency related
to
high
whole-blood levels of Prograf ( tacrolimus ). The patients should be monitored
closely and dosage
adjustments
should be considered. Some evidence suggests that lower doses should be
used
in these patients (see DOSAGE
AND ADMINISTRATION).
Myocardial Hypertrophy
Myocardial
hypertrophy has been reported in association with the administration of Prograf,
and
is generally manifested by echocardiographically demonstrated concentric
increases in
left
ventricular posterior wall and interventricular septum thickness. Hypertrophy
has been
observed
in infants, children and adults. This condition appears reversible in most cases
following
dose reduction or discontinuance of therapy. In a group of 20 patients with pre-
and
post-treatment
echocardiograms who showed evidence of myocardial hypertrophy, mean
Prograf ( tacrolimus )
whole blood concentrations during the period prior to diagnosis of myocardial
hypertrophy
ranged from 11 to 53 ng/mL in infants (N=10, age 0.4 to 2 years), 4 to 46 ng/mL
in
children (N=7, age 2 to 15 years) and 11 to 24 ng/mL in adults (N=3, age 37 to
53 years).
In
patients who develop renal failure or clinical manifestations of ventricular
dysfunction
while
receiving Prograf therapy, echocardiographic evaluation should be considered. If
myocardial
hypertrophy is diagnosed, dosage reduction or discontinuation of Prograf should
be
considered.
Information for Patients
Patients
should be informed of the need for repeated appropriate laboratory tests while
they
are
receiving Prograf. They should be given complete dosage instructions, advised of
the
potential
risks during pregnancy, and informed of the increased risk of neoplasia.
Patients
should
be informed that changes in dosage should not be undertaken without first
consulting
their
physician.
Patients
should be informed that Prograf can cause diabetes mellitus and should be
advised
of
the need to see their physician if they develop frequent urination, increased
thirst or
hunger.
As with other immunosuppressive agents, owing to the potential risk of malignant
skin
changes, exposure to sunlight and ultraviolet (UV) light should be limited by
wearing
protective
clothing and using a sunscreen with a high protection factor.
Laboratory Tests
Serum
creatinine, potassium, and fasting glucose should be assessed regularly. Routine
monitoring
of metabolic and hematologic systems should be performed as clinically
warranted.
Drug Interactions
Due
to the potential for additive or synergistic impairment of renal function, care
should be
taken
when administering Prograf with drugs that may be associated with renal
dysfunction.
These
include, but are not limited to , aminoglycosides, amphotericin B, and cisplatin.
Initial
clinical
experience with the co-administration of Prograf and cyclosporine resulted in
additive/synergistic
nephrotoxicity. Patients switched from cyclosporine to Prograf should
receive
the first Prograf dose no sooner than 24 hours after the last cyclosporine dose.
Dosing
may be further delayed in the presence of elevated cyclosporine levels.
Drugs that May Alter Prograf ( tacrolimus ) Concentrations
Since
Prograf ( tacrolimus ) is metabolized mainly by the CYP3A enzyme systems,
substances known to
inhibit
these enzymes may decrease the metabolism or increase bioavailability of Prograf ( tacrolimus )
as
indicated by increased whole blood or plasma concentrations. Drugs known to
induce
these
enzyme systems may result in an increased metabolism of Prograf ( tacrolimus )
or decreased
bioavailability
as indicated by decreased whole blood or plasma concentrations. Monitoring
of
blood concentrations and appropriate dosage adjustments are essential when such
drugs
are
used concomitantly.
*Drugs That May Increase Prograf ( tacrolimus ) Blood Concentrations:

In
a study of 6 normal volunteers, a significant increase in Prograf ( tacrolimus )
oral bioavailability
(14±5%
vs. 30±8%) was observed with concomitant ketoconazole administration (200 mg).
The
apparent oral clearance of Prograf ( tacrolimus ) during ketoconazole
administration was
significantly
decreased compared to Prograf ( tacrolimus ) alone (0.430±0.129 L/hr/kg vs.
0.148±0.043
L/hr/kg).
Overall, IV clearance of Prograf ( tacrolimus ) was not significantly changed by
ketoconazole
co-administration,
although it was highly variable between patients.
*Drugs That May Decrease Prograf ( tacrolimus ) Blood Concentrations:
Anticonvulsants
Antimicrobials
carbamazepine
rifabutin
phenobarbital
caspofungin
phenytoin
rifampin
Herbal
Preparations Other Drugs
St.
John’s Wort sirolimus
*This
table is not all inclusive.
St.
John’s Wort (Hypericum
perforatum) induces
CYP3A4 and P-glycoprotein. Since
Prograf ( tacrolimus )
is a substrate for CYP3A4, there is the potential that the use of St. John’s
Wort in
patients
receiving Prograf could result in reduced Prograf ( tacrolimus ) levels.
In
a single-dose crossover study in healthy volunteers, co-administration of Prograf ( tacrolimus )
and
magnesium-aluminum-hydroxide resulted in a 21% increase in the mean Prograf ( tacrolimus )
AUC
and
a 10% decrease in the mean Prograf ( tacrolimus ) Cmax
relative to Prograf ( tacrolimus )
administration alone.
In
a study of 6 normal volunteers, a significant decrease in Prograf ( tacrolimus )
oral bioavailability
(14±6%
vs. 7±3%) was observed with concomitant rifampin administration (600 mg). In
addition,
there was a significant increase in Prograf ( tacrolimus ) clearance (0.036±0.008
L/hr/kg vs.
0.053±0.010
L/hr/kg) with concomitant rifampin administration.
Interaction
studies with drugs used in HIV therapy have not been conducted. However,
care
should be exercised when drugs that are nephrotoxic (e.g., ganciclovir) or that
are
metabolized
by CYP3A (e.g., nelfinavir, ritonavir) are administered concomitantly with
Prograf ( tacrolimus ).
Based on a clinical study of 5 liver transplant recipients, co-administration of
Prograf ( tacrolimus )
with nelfinavir increased blood concentrations of Prograf ( tacrolimus )
significantly and, as a
result,
a reduction in the Prograf ( tacrolimus ) dose by an average of 16-fold was
needed to maintain
mean
trough Prograf ( tacrolimus ) blood concentrations of 9.7 ng/mL. Thus, frequent
monitoring of
Prograf ( tacrolimus )
blood concentrations and appropriate dosage adjustment are essential when
nelfinavir
is used concomitantly. Prograf ( tacrolimus ) may effect the pharmacokinetics of
other drugs
(e.g.,
phenytoin) and increase their concentration. Grapefruit juice affects
CYP3A-mediated
metabolism
and should be avoided (see DOSAGE AND ADMINISTATION).
Following
co-administration of Prograf ( tacrolimus ) and sirolimus (2 or 5 mg/day) in
stable renal
transplant
patients, mean Prograf ( tacrolimus ) AUC0-12
and Cmin decreased approximately by 30%
relative
to Prograf ( tacrolimus ) alone. Mean Prograf ( tacrolimus ) AUC0-12
and Cmin following co-administration of
1
mg/day of sirolimus decreased approximately 3% and 11%, respectively. The safety
and
efficacy
of Prograf ( tacrolimus ) used in combination with sirolimus for the prevention
of graft rejection
has
not been established and is not recommended.
Other Drug Interactions
Immunosuppressants
may affect vaccination. Therefore, during treatment with Prograf,
vaccination
may be less effective. The use of live vaccines should be avoided; live vaccines
may
include, but are not limited to measles, mumps, rubella, oral polio, BCG, yellow
fever,
and
TY 21a typhoid.1
Carcinogenesis, Mutagenesis and Impairment of Fertility
An
increased incidence of malignancy is a recognized complication of
immunosuppression in
recipients
of organ transplants. The most common forms of neoplasms are non-Hodgkin’s
lymphomas
and carcinomas of the skin. As with other immunosuppressive therapies, the risk
of
malignancies in Prograf recipients may be higher than in the normal, healthy
population.
Lymphoproliferative
disorders associated with Epstein-Barr Virus infection have been
seen.
It has been reported that reduction or discontinuation of immunosuppression may
cause
the lesions to regress.
No
evidence of genotoxicity was seen in bacterial (Salmonella and E. coli)
or mammalian
(Chinese
hamster lung-derived cells) in vitro assays of mutagenicity, the in vitro CHO/HGPRT
assay
of mutagenicity, or in vivo clastogenicity assays performed in mice; Prograf ( tacrolimus )
did not
cause
unscheduled DNA synthesis in rodent hepatocytes.
Carcinogenicity
studies were carried out in male and female rats and mice. In the 80-
week
mouse study and in the 104-week rat study no relationship of tumor incidence to
Prograf ( tacrolimus )
dosage was found. The highest doses used in the mouse and rat studies were 0.8
–
2.5 times (mice) and 3.5 – 7.1 times (rats) the recommended clinical dose
range of 0.1 –
0.2
mg/kg/day when corrected for body surface area.
No
impairment of fertility was demonstrated in studies of male and female rats.
Prograf ( tacrolimus ),
given orally at 1.0 mg/kg (0.7 – 1.4X the recommended clinical dose range of
0.1
–
0.2 mg/kg/day based on body surface area corrections) to male and female rats,
prior to
and
during mating, as well as to dams during gestation and lactation, was associated
with
embryolethality
and with adverse effects on female reproduction. Effects on female
reproductive
function (parturition) and embryolethal effects were indicated by a higher rate
of
pre-implantation
loss and increased numbers of undelivered and nonviable pups. When
given
at 3.2 mg/kg (2.3 – 4.6X the recommended clinical dose range based on body
surface
area
correction), Prograf ( tacrolimus ) was associated with maternal and paternal
toxicity as well as
reproductive
toxicity including marked adverse effects on estrus cycles, parturition, pup
viability,
and pup malformations.
Pregnancy: Category C
In
reproduction studies in rats and rabbits, adverse effects on the fetus were
observed mainly
at
dose levels that were toxic to dams. Prograf ( tacrolimus ) at oral doses of
0.32 and 1.0 mg/kg
during
organogenesis in rabbits was associated with maternal toxicity as well as an
increase
in
incidence of abortions; these doses are equivalent to 0.5 – 1X and 1.6 –
3.3X the
recommended
clinical dose range (0.1 – 0.2 mg/kg) based on body surface area corrections.
At
the higher dose only, an increased incidence of malformations and developmental
variations
was also seen. Prograf ( tacrolimus ), at oral doses of 3.2 mg/kg during
organogenesis in
rats,
was associated with maternal toxicity and caused an increase in late resorptions,
decreased
numbers of live births, and decreased pup weight and viability. Prograf ( tacrolimus ),
given
orally
at 1.0 and 3.2 mg/kg (equivalent to 0.7 – 1.4X and 2.3 – 4.6X the
recommended clinical
dose
range based on body surface area corrections) to pregnant rats after
organogenesis
and
during lactation, was associated with reduced pup weights.
No
reduction in male or female fertility was evident.
There
are no adequate and well-controlled studies in pregnant women. Prograf ( tacrolimus )
is
transferred
across the placenta. The use of Prograf ( tacrolimus ) during pregnancy has been
associated
with neonatal hyperkalemia and renal dysfunction. Prograf should be used during
pregnancy
only if the potential benefit to the mother justifies potential risk to the
fetus.
Nursing Mothers
Since
Prograf ( tacrolimus ) is excreted in human milk, nursing should be avoided.
Pediatric Patients
Experience
with Prograf in pediatric kidney transplant patients is limited. Successful
liver
transplants
have been performed in pediatric patients (ages up to 16 years) using Prograf.
Two
randomized active-controlled trials of Prograf in primary liver transplantation
included 56
pediatric
patients. Thirty-one patients were randomized to Prograf-based and 25 to
cyclosporine-based
therapies. Additionally, a minimum of 122 pediatric patients were studied
in
an uncontrolled trial of Prograf ( tacrolimus ) in living related donor liver
transplantation. Pediatric
patients
generally required higher doses of Prograf to maintain blood trough
concentrations of
Prograf ( tacrolimus )
similar to adult patients (see DOSAGE AND ADMINISTRATION).
ADVERSE
REACTIONS:
Liver Transplantation
The
principal adverse reactions of Prograf are tremor, headache, diarrhea,
hypertension,
nausea,
and renal dysfunction. These occur with oral and IV administration of Prograf
and
may
respond to a reduction in dosing. Diarrhea was sometimes associated with other
gastrointestinal
complaints such as nausea and vomiting.
Hyperkalemia
and hypomagnesemia have occurred in patients receiving Prograf therapy.
Hyperglycemia
has been noted in many patients; some may require insulin therapy (see
WARNINGS).
The
incidence of adverse events was determined in two randomized comparative liver
transplant
trials among 514 patients receiving Prograf ( tacrolimus ) and steroids and 515
patients
receiving
a cyclosporine-based regimen (CBIR). The proportion of patients reporting more
than
one adverse event was 99.8% in the Prograf ( tacrolimus ) group and 99.6% in the
CBIR group.
Precautions
must be taken when comparing the incidence of adverse events in the U.S.
study
to that in the European study. The 12-month posttransplant information from the
U.S.
study
and from the European study is presented below. The two studies also included
different
patient populations and patients were treated with immunosuppressive regimens of
differing
intensities. Adverse events reported in ≥ 15% in Prograf ( tacrolimus )
patients (combined

deafness, leukoencephalopathy, thrombocytopenic purpura, hemolytic-uremic
syndrome,
acute renal failure, Stevens-Johnson syndrome, stomach ulcer, glycosuria,
cardiac

OVERDOSAGE:
Limited
overdosage experience is available. Acute overdosages of up to 30 times the
intended
dose
have been reported. Almost all cases have been asymptomatic and all patients
recovered
with
no sequelae. Occasionally, acute overdosage has been followed by adverse
reactions
consistent
with those listed in the ADVERSE
REACTIONS section
except in one case where
transient
urticaria and lethargy were observed. Based on the poor aqueous solubility and
extensive
erythrocyte and plasma protein binding, it is anticipated that Prograf ( tacrolimus )
is not dialyzable
to
any significant extent; there is no experience with charcoal hemoperfusion. The
oral use of
activated
charcoal has been reported in treating acute overdoses, but experience has not
been
sufficient
to warrant recommending its use. General supportive measures and treatment of
specific
symptoms should be followed in all cases of overdosage.
In
acute oral and IV toxicity studies, mortalities were seen at or above the
following
doses:
in adult rats, 52X the recommended human oral dose; in immature rats, 16X the
recommended
oral dose; and in adult rats, 16X the recommended human IV dose (all based on
body
surface area corrections).
DOSAGE
AND ADMINISTRATION:
Prograf injection (Prograf ( tacrolimus ) injection)
For IV Infusion Only
NOTE:
Anaphylactic reactions have occurred with injectables containing castor
oil
derivatives. See WARNINGS.
In
patients unable to take oral Prograf capsules, therapy may be initiated with
Prograf injection.
The
initial dose of Prograf should be administered no sooner than 6 hours after
transplantation.
The
recommended starting dose of Prograf injection is 0.03-0.05 mg/kg/day as a
continuous IV
infusion.
Adult patients should receive doses at the lower end of the dosing range.
Concomitant
adrenal
corticosteroid therapy is recommended early post-transplantation. Continuous IV
infusion
of
Prograf injection should be continued only until the patient can tolerate oral
administration of
Prograf
capsules.
Preparation for Administration/Stability
Prograf
injection must be diluted with 0.9% Sodium Chloride Injection or 5% Dextrose
Injection to
a
concentration between 0.004 mg/mL and 0.02 mg/mL prior to use. Diluted infusion
solution
should
be stored in glass or polyethylene containers and should be discarded after 24
hours. The
diluted
infusion solution should not be stored in a PVC container due to decreased
stability and
the
potential for extraction of phthalates. In situations where more dilute
solutions are utilized
(e.g.,
pediatric dosing, etc.), PVC-free tubing should likewise be used to minimize the
potential for
significant
drug absorption onto the tubing. Parenteral drug products should be inspected
visually
for
particulate matter and discoloration prior to administration, whenever solution
and container
permit.
Due to the chemical instability of Prograf ( tacrolimus ) in alkaline media,
Prograf injection should not
be
mixed or co-infused with solutions of pH 9 or greater (e.g., ganciclovir or
acyclorvir).

Liver Transplantation
It
is recommended that patients initiate oral therapy with Prograf capsules if
possible. If IV
therapy
is necessary, conversion from IV to oral Prograf is recommended as soon as oral
therapy
can
be tolerated. This usually occurs within 2-3 days. The initial dose of Prograf
should be
administered
no sooner than 6 hours after transplantation. In a patient receiving an IV
infusion,
the
first dose of oral therapy should be given 8-12 hours after discontinuing the IV
infusion. The
recommended
starting oral dose of Prograf capsules is 0.10-0.15 mg/kg/day administered in
two
divided
daily doses every 12 hours. Co-administered grapefruit juice has been reported
to
increase
Prograf ( tacrolimus ) blood trough concentrations in liver transplant patients.
(See Drugs that May
Alter Prograf ( tacrolimus ) Concentrations).
Dosing
should be titrated based on clinical assessments of rejection and tolerability.
Lower
Prograf dosages may be sufficient as maintenance therapy. Adjunct therapy with
adrenal
corticosteroids
is recommended early post transplant.
Dosage
and typical Prograf ( tacrolimus ) whole blood trough concentrations are shown
in the table
above;
blood concentration details are described in Blood Concentration Monitoring: Liver
Transplantation below.
Kidney Transplantation
The
recommended starting oral dose of Prograf is 0.2 mg/kg/day administered every 12
hours in
two
divided doses. The initial dose of Prograf may be administered within 24 hours
of
transplantation,
but should be delayed until renal function has recovered (as indicated for
example
by a serum creatinine ≤ 4 mg/dL). Black patients may require higher doses
to achieve
comparable
blood concentrations. Dosage and typical Prograf ( tacrolimus ) whole blood
trough
concentrations
are shown in the table above; blood concentration details are described in Blood
Concentration
Monitoring: Kidney Transplantation below.
The
data in kidney transplant patients indicate that the Black patients required a
higher
dose
to attain comparable trough concentrations compared to Caucasian patients.
Pediatric Patients
Pediatric
liver transplantation patients without pre-existing renal or hepatic dysfunction
have
required and tolerated higher doses than adults to achieve similar blood
concentrations.
Therefore, it is recommended that therapy be initiated in pediatric
patients
at a starting IV dose of 0.03-0.05 mg/kg/day and a starting oral dose of 0.15-
0.20
mg/kg/day. Dose adjustments may be required. Experience in pediatric kidney
transplantation
patients is limited.
Patients with Hepatic or Renal Dysfunction
Due
to the reduced clearance and prolonged half-life, patients with severe hepatic
impairment
(Pugh
≥ 10) may require lower doses of Prograf. Close monitoring of blood
concentrations is
warranted.
Due to the potential for nephrotoxicity, patients with renal or hepatic
impairment
should
receive doses at the lowest value of the recommended IV and oral dosing ranges.
Further
reductions
in dose below these ranges may be required. Prograf therapy usually should be
delayed
up to 48 hours or longer in patients with post-operative oliguria.
Conversion from One Immunosuppressive Regimen to Another
Prograf
should not be used simultaneously with cyclosporine. Prograf or cyclosporine
should be
discontinued
at least 24 hours before initiating the other. In the presence of elevated
Prograf or
cyclosporine
concentrations, dosing with the other drug usually should be further delayed.
Blood
Concentration Monitoring
Monitoring
of Prograf ( tacrolimus ) blood concentrations in conjunction with other
laboratory and clinical
parameters
is considered an essential aid to patient management for the evaluation of
rejection,
toxicity,
dose adjustments and compliance. Factors influencing frequency of monitoring
include
but
are not limited to hepatic or renal dysfunction, the addition or discontinuation
of potentially
interacting
drugs and the posttransplant time. Blood concentration monitoring is not a
replacement
for renal and liver function monitoring and tissue biopsies.
Two
methods have been used for the assay of Prograf ( tacrolimus ), a microparticle
enzyme
immunoassay
(MEIA) and ELISA. Both methods have the same monoclonal antibody for
Prograf ( tacrolimus ).
Comparison of the concentrations in published literature to patient
concentrations
using
the current assays must be made with detailed knowledge of the assay methods and
biological
matrices employed. Whole blood is the matrix of choice and specimens should be
collected
into tubes containing ethylene diamine tetraacetic acid (EDTA) anti-coagulant.
Heparin
anti-coagulation
is not recommended because of the tendency to form clots on storage. Samples
which
are not analyzed immediately should be stored at room temperature or in a
refrigerator and
assayed
within 7 days; if samples are to be kept longer they should be deep frozen at
-20°
C for
up
to 12 months.
Liver Transplantation
Although
there is a lack of direct correlation between Prograf ( tacrolimus )
concentrations and drug efficacy,
data
from Phase II and III studies of liver transplant patients have shown an
increasing incidence
of
adverse events with increasing trough blood concentrations. Most patients are
stable when
trough
whole blood concentrations are maintained between 5 to 20 ng/mL. Long-term
posttransplant
patients
often are maintained at the low end of this target range.
Data
from the U.S. clinical trial show that Prograf ( tacrolimus ) whole blood
concentrations, as
measured
by ELISA, were most variable during the first week post-transplantation. After
this
early
period, the median trough blood concentrations, measured at intervals from the
second
week
to one year post-transplantation, ranged from 9.8 ng/mL to 19.4 ng/mL.
Therapeutic
Drug Monitoring, 1995,
Volume 17, Number 6 contains a consensus
document
and several position papers regarding the therapeutic monitoring of Prograf ( tacrolimus )
from the
1995
International Consensus Conference on Immunosuppressive Drugs. Refer to these
manuscripts
for further discussions of Prograf ( tacrolimus ) monitoring.
Kidney Transplantation
Data
from the Phase III study indicates that trough concentrations of Prograf ( tacrolimus )
in whole blood,
as
measured by IMx
were most variable
during the first week of dosing. During the first three
months,
80% of the patients maintained trough concentrations between 7-20 ng/mL, and
then
between
5-15 ng/mL, through one-year.
The
relative risk of toxicity is increased with higher trough concentrations.
Therefore,
monitoring
of whole blood trough concentrations is recommended to assist in the clinical
evaluation
of toxicity.

Your transplant team will follow your progress and watch for early signs of side effects. This is why you will have blood tests done often after your transplant. On the days you are going to have a blood test to measure the amount of PROGRAF in your body, your transplant team may ask you not to take your morning dose until after the blood sample is taken. Check with your transplant team before skipping this dose.
Can Other Medicines Affect How PROGRAF Works?
Some medicines and alcohol can affect how well PROGRAF works. After you start taking
PROGRAF:
What Are the Possible Side Effects of PROGRAF?
Tell your transplant team right away if you think you might be having a side effect.
Your transplant team will decide if it is a medicine side effect or a sign that has
nothing to do with the medicine but needs to be treated. Infection or reduced urine can be
signs of serious problems that you should discuss with your transplant team.
Your transplant team will also follow your progress and watch for the early signs of any side effects. This is why you will have blood tests done often during the first few months after your transplant. On the days you are going to have a blood test to measure the amount of PROGRAF in your body, your transplant team may ask you not to take your morning dose until after the blood sample is taken. Check with your transplant team before skipping this dose.
For Kidney Transplant Patients:
The most common side effects of PROGRAF for kidney transplant patients are infection, headache, tremors (shaking of the body), diarrhea, constipation, nausea, high blood pressure, changes in the amount of urine, and trouble sleeping.Less common side effects are abdominal pain (stomach pain), numbness or tingling in your hands or feet; loss of appetite; indigestion or "upset stomach"; vomiting; urinary tract infections; fever; pain; swelling of the hands, ankles or legs; shortness of breath or trouble breathing; cough; leg cramps; heart "fluttering," palpitations or chest pain; unusual weakness or tiredness; dizziness; confusion; changes in mood or emotions; itchy skin, skin rash, and diabetes.
For Liver Transplant Patients:
The most common side effects of PROGRAF for liver transplant patients are headache, tremors (shaking of the body), diarrhea, high blood pressure, nausea and changes in the amount of urine.Less common side effects are numbness or tingling in your hands or feet; trouble sleeping; constipation; loss of appetite; vomiting; urinary tract infections; fever, pain (especially in the back or abdomen [stomach area]); swelling of the hands, ankles, legs or abdomen; shortness of breath or trouble breathing; cough; unusual bruising; leg cramps; heart 'fluttering' or palpitations; unusual weakness or tiredness; confusion; changes in mood or emotions; itchy skin, and skin rash.
Be sure to tell your transplant team right away if you notice that you are thirstier than usual, have to urinate more often, have blurred vision or seem to get confused. These may be the early signs of high blood sugar or diabetes.
All anti-rejection medicines, including PROGRAF, suppress your body's immune system. As a result, they may increase your chances of getting infections and some kinds of cancer, including skin and lymph gland cancer (lymphoma). As usual for patients with increased risk for skin cancer, exposure to sunlight and UV light should be limited by wearing protective clothing and using a sunscreen with a high sun protection factor (SPF>15). However, getting cancer from taking an anti-rejection medicine is not common. Talk with your transplant team about any concerns or questions you have.
How Should I Store PROGRAF?
Store PROGRAF in a dry area at room temperature (77°F/25°C). Do not let the medicine
get colder than 59°F (15°C) or hotter than 86°F (30°C). For instance, do not leave
PROGRAF in the glove compartment of your car in the summer or winter. Do not keep PROGRAF
capsules in a hot or moist place such as the medicine cabinet in the bathroom.
General Advice about Prescription Medicines
Medicines are sometimes prescribed for conditions that are not mentioned in patient
information leaflets. Do not use PROGRAF for a condition for which it was not prescribed.
Do not give PROGRAF to other people.
Note: This information is strictly for educational purposes and should not
