.
5 WARNINGS AND PRECAUTIONS
WARNINGS AND PRECAUTIONS SECTION
5.1 Pancreatitis
SPL UNCLASSIFIED SECTION
Acute pancreatitis,
including fatal pancreatitis, has been reported in patients treated
with linagliptin. In the CARMELINA trial
[see
Clinical Studies (14.3)]
, acute pancreatitis was
reported in 9 (0.3%) patients treated with linagliptin and in 5 (0.1%)
patients treated with placebo. Two patients treated with linagliptin
in the CARMELINA trial had acute pancreatitis with a fatal outcome.
There have been postmarketing reports of acute pancreatitis, including
fatal pancreatitis, in patients treated with linagliptin.
Take careful notice
of potential signs and symptoms of pancreatitis. If pancreatitis is
suspected, promptly discontinue GLYXAMBI and initiate appropriate
management. It is unknown whether patients with a history of pancreatitis
are at increased risk for the development of pancreatitis while using
GLYXAMBI.Take careful notice
of potential signs and symptoms of pancreatitis. If pancreatitis is
suspected, promptly discontinue GLYXAMBI and initiate appropriate
management. It is unknown whether patients with a history of pancreatitis
are at increased risk for the development of pancreatitis while using
GLYXAMBI.
5.2 Heart Failure
SPL UNCLASSIFIED SECTION
An association between DPP-4 inhibitor
treatment and heart failure has been observed in cardiovascular outcomes
trials for two other members of the DPP-4 inhibitor class. These trials
evaluated patients with type 2 diabetes mellitus and atherosclerotic
cardiovascular disease.
Consider the risks and benefits of GLYXAMBI prior to initiating treatment
in patients at risk for heart failure, such as those with a prior
history of heart failure and a history of renal impairment, and observe
these patients for signs and symptoms of heart failure during therapy.
Advise patients of the characteristic symptoms of heart failure and
to immediately report such symptoms. If heart failure develops, evaluate
and manage according to current standards of care and consider discontinuation
of GLYXAMBI.
5.3 Hypotension
SPL UNCLASSIFIED SECTION
Empagliflozin causes intravascular
volume contraction. Symptomatic hypotension may occur after initiating
empagliflozin
[see
Adverse Reactions (6.1)]
particularly in patients with renal impairment, the elderly,
in patients with low systolic blood pressure, and in patients on diuretics.
Before initiating GLYXAMBI, assess for volume contraction and correct
volume status if indicated. Monitor for signs and symptoms of hypotension
after initiating therapy and increase monitoring in clinical situations
where volume contraction is expected
[see
Use in Specific Populations (8.5)]
.
5.4 Ketoacidosis
SPL UNCLASSIFIED SECTION
Reports of ketoacidosis, a serious
life-threatening condition requiring urgent hospitalization have been
identified in postmarketing surveillance in patients with type 1 and
type 2 diabetes mellitus receiving sodium glucose co-transporter-2
(SGLT2) inhibitors, including empagliflozin. Fatal cases of ketoacidosis
have been reported in patients taking empagliflozin. GLYXAMBI is not
indicated for the treatment of patients with type 1 diabetes mellitus
[see
Indications and Usage (1)]
.
Patients treated with GLYXAMBI
who present with signs and symptoms consistent with severe metabolic
acidosis should be assessed for ketoacidosis regardless of presenting
blood glucose levels, as ketoacidosis associated with GLYXAMBI may
be present even if blood glucose levels are less than 250 mg/dL. If
ketoacidosis is suspected, GLYXAMBI should be discontinued, patient
should be evaluated, and prompt treatment should be instituted. Treatment
of ketoacidosis may require insulin, fluid and carbohydrate replacement.
In many of the postmarketing reports,
and particularly in patients with type 1 diabetes, the presence of
ketoacidosis was not immediately recognized and institution of treatment
was delayed because presenting blood glucose levels were below those
typically expected for diabetic ketoacidosis (often less than 250
mg/dL). Signs and symptoms at presentation were consistent with dehydration
and severe metabolic acidosis and included nausea, vomiting, abdominal
pain, generalized malaise, and shortness of breath. In some but not
all cases, factors predisposing to ketoacidosis such as insulin dose
reduction, acute febrile illness, reduced caloric intake due to illness
or surgery, pancreatic disorders suggesting insulin deficiency (e.g.,
type 1 diabetes, history of pancreatitis or pancreatic surgery), and
alcohol abuse were identified.
Before initiating GLYXAMBI, consider factors
in the patient history that may predispose to ketoacidosis including
pancreatic insulin deficiency from any cause, caloric restriction,
and alcohol abuse. In patients treated with GLYXAMBI consider monitoring
for ketoacidosis and temporarily discontinuing GLYXAMBI in clinical
situations known to predispose to ketoacidosis (e.g., prolonged fasting
due to acute illness or surgery).
5.5 Acute Kidney Injury and Impairment in Renal Function
SPL UNCLASSIFIED SECTION
Empagliflozin causes intravascular volume
contraction
[see
Warnings and Precautions
(5.3)]
and can cause renal impairment
[see
Adverse Reactions (6.1)]
. There have been
postmarketing reports of acute kidney injury, some requiring hospitalization
and dialysis, in patients receiving SGLT2 inhibitors, including empagliflozin;
some reports involved patients younger than 65 years of age.
Before initiating GLYXAMBI, consider
factors that may predispose patients to acute kidney injury including
hypovolemia, chronic renal insufficiency, congestive heart failure
and concomitant medications (diuretics, ACE inhibitors, ARBs, NSAIDs).
Consider temporarily discontinuing GLYXAMBI in any setting of reduced
oral intake (such as acute illness or fasting) or fluid losses (such
as gastrointestinal illness or excessive heat exposure); monitor patients
for signs and symptoms of acute kidney injury. If acute kidney injury
occurs, discontinue GLYXAMBI promptly and institute treatment.
Empagliflozin increases serum
creatinine and decreases eGFR. Patients with hypovolemia may be more
susceptible to these changes. Renal function abnormalities can occur
after initiating GLYXAMBI
[see
Adverse Reactions
(6.1)]
. Renal function should be evaluated prior to
initiation of GLYXAMBI and monitored periodically thereafter. More
frequent renal function monitoring is recommended in patients with
an eGFR below 60 mL/min/1.73 m
2. Use of
GLYXAMBI is not recommended when eGFR is persistently less than 45
mL/min/1.73 m
2 and is contraindicated in
patients with an eGFR less than 30 mL/min/1.73 m
2 [see
Dosage and Administration (2.2),
Contraindications (4) and
Use in Specific Populations (8.6)]
.
5.6 Urosepsis and Pyelonephritis
SPL UNCLASSIFIED SECTION
There have been postmarketing
reports of serious urinary tract infections including urosepsis and
pyelonephritis requiring hospitalization in patients receiving SGLT2
inhibitors, including empagliflozin. Treatment with SGLT2 inhibitors
increases the risk for urinary tract infections. Evaluate patients
for signs and symptoms of urinary tract infections and treat promptly,
if indicated
[see
Adverse Reactions (6)]
.
5.7 Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues
SPL UNCLASSIFIED SECTION
Insulin and insulin secretagogues
are known to cause hypoglycemia. The use of empagliflozin or linagliptin
in combination with an insulin secretagogue (e.g., sulfonylurea) or
insulin was associated with a higher rate of hypoglycemia compared
with placebo in a clinical trial. Therefore, a lower dose of the insulin
secretagogue or insulin may be required to reduce the risk of hypoglycemia
when used in combination with GLYXAMBI.
5.8 Necrotizing Fasciitis of the Perineum (Fournier's Gangrene)
SPL UNCLASSIFIED SECTION
Reports of necrotizing
fasciitis of the perineum (Fournier's gangrene), a rare but serious
and life-threatening necrotizing infection requiring urgent surgical
intervention, have been identified in postmarketing surveillance in
patients with diabetes mellitus receiving SGLT2 inhibitors, including
empagliflozin. Cases have been reported in both females and males.
Serious outcomes have included hospitalization, multiple surgeries,
and death.
Patients treated with GLYXAMBI
presenting with pain or tenderness, erythema, or swelling in the genital
or perineal area, along with fever or malaise, should be assessed
for necrotizing fasciitis. If suspected, start treatment immediately
with broad-spectrum antibiotics and, if necessary, surgical debridement.
Discontinue GLYXAMBI, closely monitor blood glucose levels, and provide
appropriate alternative therapy for glycemic control.
5.9 Genital Mycotic Infections
SPL UNCLASSIFIED SECTION
Empagliflozin increases the risk for genital mycotic infections
[see
Adverse Reactions (6.1)]
.
Patients with a history of chronic or recurrent genital mycotic infections
were more likely to develop genital mycotic infections. Monitor and
treat as appropriate.
5.10 Hypersensitivity Reactions
SPL UNCLASSIFIED SECTION
There
have been postmarketing reports of serious hypersensitivity reactions
in patients treated with linagliptin (one of the components of GLYXAMBI).
These reactions include anaphylaxis, angioedema, and exfoliative skin
conditions. Onset of these reactions occurred within the first 3 months
after initiation of treatment with linagliptin, with some reports
occurring after the first dose.
Angioedema has also been reported with other
dipeptidyl peptidase-4 (DPP-4) inhibitors. Use caution in a patient
with a history of angioedema to another DPP-4 inhibitor because it
is unknown whether such patients will be predisposed to angioedema
with GLYXAMBI.
There
have been postmarketing reports of serious hypersensitivity reactions,
(e.g., angioedema) in patients treated with empaglifozin (one of the
components of GLYXAMBI).
If a hypersensitivity reaction occurs, discontinue GLYXAMBI, treat
promptly per standard of care, and monitor until signs and symptoms
resolve. GLYXAMBI is contraindicated in patients with a previous serious
hypersensitivity reaction to linagliptin or empagliflozin
[see
Contraindications (4)]
.
Increases in LDL-C can occur with empagliflozin
[see
Adverse Reactions (6.1)]
.
Monitor and treat as appropriate.
5.12 Severe and Disabling Arthralgia
SPL UNCLASSIFIED SECTION
There have been postmarketing reports of severe and disabling arthralgia
in patients taking DPP-4 inhibitors. The time to onset of symptoms
following initiation of drug therapy varied from one day to years.
Patients experienced relief of symptoms upon discontinuation of the
medication. A subset of patients experienced a recurrence of symptoms
when restarting the same drug or a different DPP-4 inhibitor. Consider
as a possible cause for severe joint pain and discontinue drug if
appropriate.
5.13 Bullous Pemphigoid
SPL UNCLASSIFIED SECTION
Bullous pemphigoid
was reported in 7 (0.2%) patients treated with linagliptin compared
to none in patients treated with placebo in the CARMELINA trial
[see
Clinical Studies (14.3)]
,
and 3 of these patients were hospitalized due to bullous pemphigoid.
Postmarketing cases of bullous pemphigoid requiring hospitalization
have been reported with DPP-4 inhibitor use. In reported cases, patients
typically recovered with topical or systemic immunosuppressive treatment
and discontinuation of the DPP-4 inhibitor. Tell patients to report
development of blisters or erosions while receiving GLYXAMBI. If bullous
pemphigoid is suspected, GLYXAMBI should be discontinued and referral
to a dermatologist should be considered for diagnosis and appropriate
treatment.
6 ADVERSE REACTIONS
ADVERSE REACTIONS SECTION
The following important adverse
reactions are described below and elsewhere in the labeling:
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.
SPL UNCLASSIFIED SECTION
Empagliflozin and Linagliptin
The safety of concomitantly administered empagliflozin
(daily dose 10 mg or 25 mg) and linagliptin (daily dose 5 mg) has
been evaluated in a total of 1363 patients with type 2 diabetes treated
for up to 52 weeks in active-controlled clinical trials. The most
common adverse reactions with concomitant administration of empagliflozin
and linagliptin based on a pooled analyses of these studies are shown

in 0%, 1.7%, and 1.5% for placebo, empagliflozin 10 mg, and empagliflozin
25 mg, respectively.
Empagliflozin causes an osmotic diuresis, which may lead to intravascular
volume contraction and adverse reactions related to volume depletion.
SPL UNCLASSIFIED SECTION
Linagliptin
Adverse reactions reported in ≥2% of patients treated with linagliptin
5 mg and more commonly than in patients treated with placebo included:
nasopharyngitis (7.0% and 6.1%), diarrhea (3.3% and 3.0%), and cough
(2.1% and 1.4%).
Other
adverse reactions reported in clinical studies with treatment of linagliptin
monotherapy were hypersensitivity (e.g., urticaria, angioedema, localized
skin exfoliation, or bronchial hyperreactivity) and myalgia.
In the clinical trial program,
pancreatitis was reported in 15.2 cases per 10,000 patient year exposure
while being treated with linagliptin compared with 3.7 cases per 10,000
patient year exposure while being treated with comparator (placebo
and active comparator, sulfonylurea). Three additional cases of pancreatitis
were reported following the last administered dose of linagliptin.

7 DRUG INTERACTIONS
DRUG INTERACTIONS SECTION
7.1 Drug Interactions with Empagliflozin
SPL UNCLASSIFIED SECTION
SPL UNCLASSIFIED SECTION
Diuretics
Coadministration of empagliflozin with diuretics resulted in increased
urine volume and frequency of voids, which might enhance the potential
for volume depletion
[see
Warnings and Precautions
(5.3)]
.
SPL UNCLASSIFIED SECTION
Positive Urine Glucose Test
Monitoring glycemic control with urine glucose
tests is not recommended in patients taking SGLT2 inhibitors as SGLT2
inhibitors increase urinary glucose excretion and will lead to positive
urine glucose tests. Use alternative methods to monitor glycemic control.
SPL UNCLASSIFIED SECTION
Interference with 1,5-anhydroglucitol (1,5-AG) Assay
Monitoring glycemic control with
1,5-AG assay is not recommended as measurements of 1,5-AG are unreliable
in assessing glycemic control in patients taking SGLT2 inhibitors.
Use alternative methods to monitor glycemic control.
7.2 Drug Interactions with Linagliptin
SPL UNCLASSIFIED SECTION
SPL UNCLASSIFIED SECTION
Inducers of P-glycoprotein or CYP3A4 Enzymes
Rifampin decreased linagliptin
exposure, suggesting that the efficacy of linagliptin may be reduced
when administered in combination with a strong P-gp or CYP3A4 inducer.
Therefore, use of alternative treatments is strongly recommended when
linagliptin is to be administered with a strong P-gp or CYP3A4 inducer
[see
Clinical Pharmacology (12.3)]
.
7.3 Insulin or Insulin Secretagogues
SPL UNCLASSIFIED SECTION
Coadministration of GLYXAMBI with an insulin secretagogue (e.g.,

8 USE IN SPECIFIC POPULATIONS
USE IN SPECIFIC POPULATIONS SECTION
8.1 Pregnancy
PREGNANCY SECTION
SPL UNCLASSIFIED SECTION
Risk Summary
Based on animal data showing adverse renal effects from empagliflozin,
GLYXAMBI is not recommended during the second and third trimesters
of pregnancy.
The limited
available data with GLYXAMBI, linagliptin, or empagliflozin in pregnant
women are not sufficient to determine a drug-associated risk for major
birth defects and miscarriage. There are risks to the mother and fetus
associated with poorly controlled diabetes in pregnancy
(see
Clinical Considerations).
In animal studies, adverse renal changes were
observed in rats when empagliflozin was administered during a period
of renal development corresponding to the late second and third trimesters
of human pregnancy. Doses approximately 13-times the maximum clinical
dose caused renal pelvic and tubule dilatations that were reversible.
No adverse developmental effects were observed when the combination
of linagliptin and empagliflozin was administered to pregnant rats
during the period of organogenesis at exposures approximately 253
and 353 times the clinical exposure
(see
Data).
The estimated background risk of major birth defects is 6-10% in
women with pre-gestational diabetes with a HbA1c >7 and has been reported
to be as high as 20-25% in women with HbA1c >10. The estimated background
risk of miscarriage for the indicated population is unknown. In the
U.S. general population, the estimated background risk of major birth
defects and miscarriage in clinically recognized pregnancies is 2-4%
and 15-20%, respectively.
SPL UNCLASSIFIED SECTION
Clinical Considerations
SPL UNCLASSIFIED SECTION
Disease-associated maternal and/or embryo/fetal risk: Poorly
controlled diabetes in pregnancy increases the maternal risk for diabetic
ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery,
and delivery complications. Poorly controlled diabetes increases the
fetal risk for major birth defects, stillbirth, and macrosomia related
morbidity.
SPL UNCLASSIFIED SECTION
Data
SPL UNCLASSIFIED SECTION
Animal Data
The combined components administered during the period of organogenesis
were not teratogenic in rats up to and including a combined dose of
700 mg/kg/day empagliflozin and 140 mg/kg/day linagliptin, which is
253 and 353 times the clinical exposure. A pre- and post-natal development
study was not conducted with the combined components of GLYXAMBI.
SPL UNCLASSIFIED SECTION
Empagliflozin: Empagliflozin dosed directly to juvenile
rats from postnatal day (PND) 21 until PND 90 at doses of 1, 10, 30,
and 100 mg/kg/day caused increased kidney weights and renal tubular
and pelvic dilatation at 100 mg/kg/day, which approximates 13-times
the maximum clinical dose of 25 mg, based on AUC. These findings were
not observed after a 13-week drug-free recovery period. These outcomes
occurred with drug exposure during periods of renal development in
rats that correspond to the late second and third trimester of human
renal development.
In
embryo-fetal development studies in rats and rabbits, empagliflozin
was administered for intervals coinciding with the first trimester
period of organogenesis in humans. Doses up to 300 mg/kg/day, which
approximates 48-times (rats) and 128-times (rabbits) the maximum clinical
dose of 25 mg (based on AUC), did not result in adverse developmental
effects. In rats, at higher doses of empagliflozin causing maternal
toxicity, malformations of limb bones increased in fetuses at 700
mg/kg/day or 154-times the 25 mg maximum clinical dose. Empagliflozin
crosses the placenta and reaches fetal tissues in rats. In the rabbit,
higher doses of empagliflozin resulted in maternal and fetal toxicity
at 700 mg/kg/day, or 139-times the 25 mg maximum clinical dose.
In pre- and postnatal development
studies in pregnant rats, empagliflozin was administered from gestation
day 6 through to lactation day 20 (weaning) at up to 100 mg/kg/day
(approximately 16 times the 25 mg maximum clinical dose) without maternal
toxicity. Reduced body weight was observed in the offspring at greater
than or equal to 30 mg/kg/day (approximately 4 times the 25 mg maximum
clinical dose).
SPL UNCLASSIFIED SECTION
Linagliptin: No adverse developmental outcome was observed
when linagliptin was administered to pregnant Wistar Han rats and
Himalayan rabbits during the period of organogenesis at doses up to
240 mg/kg/day and 150 mg/kg/day, respectively. These doses represent
approximately 943 times (rats) and 1943 times (rabbits) the 5 mg maximum
clinical dose, based on exposure. No adverse functional, behavioral,
or reproductive outcome was observed in offspring following administration
of linagliptin to Wistar Han rats from gestation day 6 to lactation
day 21 at a dose 49 times the maximum recommended human dose, based
on exposure.
Linagliptin
crosses the placenta into the fetus following oral dosing in pregnant
rats and rabbits.
8.2 Lactation
SPL UNCLASSIFIED SECTION
SPL UNCLASSIFIED SECTION
Risk Summary
There is no information regarding the presence of GLYXAMBI, or its
individual components in human milk, the effects on the breastfed
infant, or the effects on milk production. Empagliflozin and linagliptin
are present in rat milk
(see
Data)
. Since human kidney maturation occurs
in utero and during the first 2 years of life when lactational exposure may
occur, there may be risk to the developing human kidney.
Because of the potential for serious
adverse reactions in a breastfed infant, including the potential for
empagliflozin to affect postnatal renal development, advise patients
that use of GLYXAMBI is not recommended while breastfeeding
.
SPL UNCLASSIFIED SECTION
Data
Empagliflozin
was present at a low level in rat fetal tissues after a single oral
dose to the dams at gestation day 18. In rat milk, the mean milk to
plasma ratio ranged from 0.634 -5, and was greater than one from 2
to 24 hours post-dose. The mean maximal milk to plasma ratio of 5
occurred at 8 hours post-dose, suggesting accumulation of empagliflozin
in the milk. Juvenile rats directly exposed to empagliflozin showed
a risk to the developing kidney (renal pelvic and tubular dilatations)
during maturation.

Empagliflozin
No empagliflozin dosage change is recommended based on age
[see
Dosage and Administration (2)]
. A total of 2721 (32%) patients treated with empagliflozin were
65 years of age and older, and 491 (6%) were 75 years of age and older.
Empagliflozin is expected to have diminished efficacy in elderly patients
with renal impairment
[see

Populations (8.6)]
. The risk of volume depletion-related
adverse reactions increased in patients who were 75 years of age and
older to 2.1%, 2.3%, and 4.4% for placebo, empagliflozin 10 mg, and
empagliflozin 25 mg. The risk of urinary tract infections increased
in patients who were 75 years of age and older to 10.5%, 15.7%, and
15.1% in patients randomized to placebo, empagliflozin 10 mg, and
empagliflozin 25 mg, respectively

SPL UNCLASSIFIED SECTION
Linagliptin
There were 4040 type 2 diabetes patients treated with linagliptin
5 mg from 15 clinical trials of linagliptin; 1085 (27%) were 65 years
and over, while 131 (3%) were 75 years and over. Of these patients,
2566 were enrolled in 12 double-blind placebo-controlled studies;
591 (23%) were 65 years and over, while 82 (3%) were 75 years and
over. No overall differences in safety or effectiveness were observed
between patients 65 years and over and younger patients. Therefore,
no dose adjustment is recommended in the elderly population. While
clinical studies of linagliptin have not identified differences in
response between the elderly and younger patients, greater sensitivity
of some older individuals cannot be ruled out.
The glucose lowering benefit of empagliflozin 25 mg decreased in
patients with worsening renal function. The risks of renal impairment
[see
Warnings and Precautions (5.5)]
, volume depletion adverse reactions and urinary tract infection-related
adverse reactions increased with worsening renal function.
In the event of an overdose with
GLYXAMBI, contact the Poison Control Center. Removal of empagliflozin
by hemodialysis has not been studied, and removal of linagliptin by
hemodialysis or peritoneal dialysis is unlikely.

12 CLINICAL PHARMACOLOGY
CLINICAL PHARMACOLOGY SECTION
12.1 Mechanism of Action
MECHANISM OF ACTION SECTION
SPL UNCLASSIFIED SECTION
GLYXAMBI
GLYXAMBI
combines 2 antihyperglycemic agents with complementary mechanisms
of action to improve glycemic control in patients with type 2 diabetes:
empagliflozin, a sodium-glucose co-transporter 2 (SGLT2) inhibitor,
and linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor.
SPL UNCLASSIFIED SECTION
Empagliflozin
Sodium-glucose co-transporter 2 (SGLT2) is the predominant transporter
responsible for reabsorption of glucose from the glomerular filtrate
back into the circulation. Empagliflozin is an inhibitor of SGLT2.
By inhibiting SGLT2, empagliflozin reduces renal reabsorption of filtered
glucose and lowers the renal threshold for glucose, and thereby increases
urinary glucose excretion.
SPL UNCLASSIFIED SECTION
Linagliptin
Linagliptin is an inhibitor of DPP-4, an enzyme that degrades the
incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent
insulinotropic polypeptide (GIP). Thus, linagliptin increases the
concentrations of active incretin hormones, stimulating the release
of insulin in a glucose-dependent manner and decreasing the levels
of glucagon in the circulation. Both incretin hormones are involved
in the physiological regulation of glucose homeostasis. Incretin hormones
are secreted at a low basal level throughout the day and levels rise
immediately after meal intake. GLP-1 and GIP increase insulin biosynthesis
and secretion from pancreatic beta cells in the presence of normal
and elevated blood glucose levels. Furthermore, GLP-1 also reduces
glucagon secretion from pancreatic alpha cells, resulting in a reduction
in hepatic glucose output.
12.2 Pharmacodynamics
PHARMACODYNAMICS SECTION
SPL UNCLASSIFIED SECTION
Empagliflozin
SPL UNCLASSIFIED SECTION
Urinary Glucose Excretion
In patients with type 2 diabetes, urinary
glucose excretion increased immediately following a dose of empagliflozin
and was maintained at the end of a 4-week treatment period averaging
at approximately 64 grams per day with 10 mg empagliflozin and 78
grams per day with 25 mg empagliflozin once daily.
SPL UNCLASSIFIED SECTION
Urinary Volume
In a 5-day study, mean 24-hour urine volume
increase from baseline was 341 mL on Day 1 and 135 mL on Day 5 of
empagliflozin 25 mg once daily treatment.
SPL UNCLASSIFIED SECTION
Cardiac Electrophysiology
In a randomized, placebo-controlled, active-comparator,
crossover study, 30 healthy subjects were administered a single oral
dose of empagliflozin 25 mg, empagliflozin 200 mg (8 times the maximum
recommended dose), moxifloxacin, and placebo. No increase in QTc was
observed with either 25 mg or 200 mg empagliflozin.
SPL UNCLASSIFIED SECTION
Linagliptin
Linagliptin binds to DPP-4 in a reversible manner and increases the
concentrations of incretin hormones. Linagliptin glucose-dependently
increases insulin secretion and lowers glucagon secretion, thus resulting
in a better regulation of the glucose homeostasis. Linagliptin binds
selectively to DPP-4 and selectively inhibits DPP-4, but not DPP-8
or DPP-9 activity
in vitro at concentrations approximating
therapeutic exposures.
SPL UNCLASSIFIED SECTION
Cardiac Electrophysiology
In a randomized, placebo-controlled, active-comparator,
4-way crossover study, 36 healthy subjects were administered a single
oral dose of linagliptin 5 mg, linagliptin 100 mg (20 times the recommended
dose), moxifloxacin, and placebo. No increase in QTc was observed
with either the recommended dose of 5 mg or the 100-mg dose. At the
100-mg dose, peak linagliptin plasma concentrations were approximately
38-fold higher than the peak concentrations following a 5-mg dose.
12.3 Pharmacokinetics
PHARMACOKINETICS SECTION
SPL UNCLASSIFIED SECTION
GLYXAMBI
The
results of the bioequivalence study in healthy subjects demonstrated
that GLYXAMBI (25 mg empagliflozin/5 mg linagliptin) combination tablets
are bioequivalent to coadministration of corresponding doses of empagliflozin
and linagliptin as individual tablets. Administration of the fixed-dose
combination with food resulted in no change in overall exposure of
empagliflozin or linagliptin; however, the peak exposure was decreased
39% and 32% for empagliflozin and linagliptin, respectively. These
changes are not likely to be clinically significant.
SPL UNCLASSIFIED SECTION
Absorption
SPL UNCLASSIFIED SECTION
Empagliflozin
The pharmacokinetics of empagliflozin has been characterized in healthy
volunteers and patients with type 2 diabetes and no clinically relevant
differences were noted between the two populations. After oral administration,
peak plasma concentrations of empagliflozin were reached at 1.5 hours
post-dose. Thereafter, plasma concentrations declined in a biphasic
manner with a rapid distribution phase and a relatively slow terminal
phase. The steady state mean plasma AUC and C
max were 1870 nmol∙h/L and 259 nmol/L, respectively, with 10 mg empagliflozin
once daily treatment, and 4740 nmol∙h/L and 687 nmol/L, respectively,
with 25 mg empagliflozin once daily treatment. Systemic exposure of
empagliflozin increased in a dose-proportional manner in the therapeutic
dose range. The single-dose and steady-state pharmacokinetic parameters
of empagliflozin were similar, suggesting linear pharmacokinetics
with respect to time.
Administration of 25 mg empagliflozin after intake of a high-fat
and high-calorie meal resulted in slightly lower exposure; AUC decreased
by approximately 16% and C
max decreased by
approximately 37%, compared to fasted condition. The observed effect
of food on empagliflozin pharmacokinetics was not considered clinically
relevant and empagliflozin may be administered with or without food.
SPL UNCLASSIFIED SECTION
Linagliptin
The absolute bioavailability of linagliptin is approximately 30%.
High-fat meal reduced C
max by 15% and increased
AUC by 4%; this effect is not clinically relevant. Linagliptin may
be administered with or without food.
SPL UNCLASSIFIED SECTION
Distribution
SPL UNCLASSIFIED SECTION
Empagliflozin
The apparent steady-state volume of distribution was estimated to
be 73.8 L based on a population pharmacokinetic analysis. Following
administration of an oral [
14C]-empagliflozin
solution to healthy subjects, the red blood cell partitioning was
approximately 36.8% and plasma protein binding was 86.2%.
SPL UNCLASSIFIED SECTION
Linagliptin
The mean apparent volume of distribution at steady state following
a single intravenous dose of linagliptin 5 mg to healthy subjects
is approximately 1110 L, indicating that linagliptin extensively distributes
to the tissues. Plasma protein binding of linagliptin is concentration-dependent,
decreasing from about 99% at 1 nmol/L to 75% to 89% at ≥30 nmol/L,
reflecting saturation of binding to DPP-4 with increasing concentration
of linagliptin. At high concentrations, where DPP-4 is fully saturated,
70% to 80% of linagliptin remains bound to plasma proteins and 20%
to 30% is unbound in plasma. Plasma binding is not altered in patients
with renal or hepatic impairment.
SPL UNCLASSIFIED SECTION
Metabolism
SPL UNCLASSIFIED SECTION
Empagliflozin
No major metabolites of empagliflozin were
detected in human plasma and the most abundant metabolites were three
glucuronide conjugates (2-O-, 3-O-, and 6-O-glucuronide). Systemic
exposure of each metabolite was less than 10% of total drug-related
material.
In vitro studies suggested that the primary
route of metabolism of empagliflozin in humans is glucuronidation
by the uridine 5'-diphospho-glucuronosyltransferases UGT2B7, UGT1A3,
UGT1A8, and UGT1A9.
SPL UNCLASSIFIED SECTION
Linagliptin
Following oral administration, the majority (about 90%) of linagliptin
is excreted unchanged, indicating that metabolism represents a minor
elimination pathway. A small fraction of absorbed linagliptin is metabolized
to a pharmacologically inactive metabolite, which shows a steady-state
exposure of 13.3% relative to linagliptin.
SPL UNCLASSIFIED SECTION
Elimination
SPL UNCLASSIFIED SECTION
Empagliflozin
The apparent terminal elimination half-life
of empagliflozin was estimated to be 12.4 h and apparent oral clearance
was 10.6 L/h based on the population pharmacokinetic analysis. Following
once-daily dosing, up to 22% accumulation, with respect to plasma
AUC, was observed at steady-state, which was consistent with empagliflozin
half-life. Following administration of an oral [
14C]-empagliflozin solution to healthy subjects, approximately 95.6%
of the drug-related radioactivity was eliminated in feces (41.2%)
or urine (54.4%). The majority of drug-related radioactivity recovered
in feces was unchanged parent drug and approximately half of drug-related
radioactivity excreted in urine was unchanged parent drug.
SPL UNCLASSIFIED SECTION
Linagliptin
Following administration of an oral [
14C]-linagliptin dose to healthy subjects, approximately 85% of the
administered radioactivity was eliminated via the enterohepatic system
(80%) or urine (5%) within 4 days of dosing. Renal clearance at steady
state was approximately 70 mL/min.

Empagliflozin: In patients with mild (eGFR: 60 to less
than 90 mL/min/1.73 m
2), moderate (eGFR:
30 to less than 60 mL/min/1.73 m
2), and
severe (eGFR: less than 30 mL/min/1.73 m
2) renal impairment and subjects with kidney failure/end stage renal
disease (ESRD) patients, AUC of empagliflozin increased by approximately
18%, 20%, 66%, and 48%, respectively, compared to subjects with normal
renal function. Peak plasma levels of empagliflozin were similar in
subjects with moderate renal impairment and kidney failure/ESRD compared
to patients with normal renal function. Peak plasma levels of empagliflozin
were roughly 20% higher in subjects with mild and severe renal impairment
as compared to subjects with normal renal function. Population pharmacokinetic
analysis showed that the apparent oral clearance of empagliflozin
decreased, with a decrease in eGFR leading to an increase in drug
exposure. However, the fraction of empagliflozin that was excreted
unchanged in urine, and urinary glucose excretion, declined with decrease
in eGFR.
SPL UNCLASSIFIED SECTION
Linagliptin: An open-label pharmacokinetic study evaluated
the pharmacokinetics of linagliptin 5 mg in male and female patients
with varying degrees of chronic renal impairment. The study included
6 healthy subjects with normal renal function (creatinine clearance
[CrCl] ≥80 mL/min), 6 patients with mild renal impairment (CrCl 50
to <80 mL/min), 6 patients with moderate renal impairment (CrCl
30 to <50 mL/min), 10 patients with type 2 diabetes and severe
renal impairment (CrCl <30 mL/min), and 11 patients with type 2
diabetes and normal renal function. Creatinine clearance was measured
by 24-hour urinary creatinine clearance measurements or estimated
from serum creatinine based on the Cockcroft-Gault formula.
Under steady-state conditions,
linagliptin exposure in patients with mild renal impairment was comparable
to healthy subjects.
In patients with moderate renal impairment under steady-state conditions,
mean exposure of linagliptin increased (AUC
τ,ss by 71% and C
max by 46%) compared with healthy
subjects. This increase was not associated with a prolonged accumulation
half-life, terminal half-life, or an increased accumulation factor.
Renal excretion of linagliptin was below 5% of the administered dose
and was not affected by decreased renal function. Patients with type
2 diabetes and severe renal impairment showed steady-state exposure
approximately 40% higher than that of patients with type 2 diabetes
and normal renal function (increase in AUC
τ,ss by 42% and C
max by 35%). For both type 2
diabetes groups, renal excretion was below 7% of the administered
dose.
These findings
were further supported by the results of population pharmacokinetic
analyses.

48%, respectively, compared to subjects with normal hepatic function.
SPL UNCLASSIFIED SECTION
Linagliptin: In patients with mild hepatic impairment (Child-Pugh

τ,ss) of
linagliptin was approximately 25% lower and C
max,ss was approximately 36% lower than in healthy subjects. In patients
with moderate hepatic impairment (Child-Pugh class B), AUC
ss of linagliptin was about 14% lower and C
max,ss was approximately 8% lower than in healthy subjects.
Patients with severe hepatic impairment (Child-Pugh class C) had comparable
exposure of linagliptin in terms of AUC
0-24 and approximately 23% lower C
max compared
with healthy subjects. Reductions in the pharmacokinetic parameters
seen in patients with hepatic impairment did not result in reductions
in DPP-4 inhibition.

SPL UNCLASSIFIED SECTION
In vitro Assessment of
Drug Interactions
In vitro data suggest that
the primary route of metabolism of empagliflozin in humans is glucuronidation
by the uridine 5'-diphospho-glucuronosyltransferases UGT2B7, UGT1A3,
UGT1A8, and UGT1A9. Empagliflozin does not inhibit, inactivate, or
induce CYP450 isoforms. Empagliflozin also does not inhibit UGT1A1.
Therefore, no effect of empagliflozin is anticipated on concomitantly
administered drugs that are substrates of the major CYP450 isoforms
or UGT1A1. The effect of UGT induction (e.g., induction by rifampicin
or any other UGT enzyme inducer) on empagliflozin exposure has not
been evaluated.
Empagliflozin
is a substrate for P-glycoprotein (P-gp) and breast cancer resistance
protein (BCRP), but it does not inhibit these efflux transporters
at therapeutic doses. Based on
in vitro studies,
empagliflozin is considered unlikely to cause interactions with drugs
that are P-gp substrates. Empagliflozin is a substrate of the human
uptake transporters OAT3, OATP1B1, and OATP1B3, but not OAT1 and OCT2.
Empagliflozin does not inhibit any of these human uptake transporters
at clinically relevant plasma concentrations and, therefore, no effect
of empagliflozin is anticipated on concomitantly administered drugs
that are substrates of these uptake transporters.
SPL UNCLASSIFIED SECTION
In vivo Assessment of
Drug Interactions
No dose adjustment of empagliflozin is recommended
when coadministered with commonly prescribed medicinal products based
on results of the described pharmacokinetic studies. Empagliflozin
pharmacokinetics were similar with and without coadministration of
metformin, glimepiride, pioglitazone, sitagliptin, linagliptin, warfarin,
verapamil, ramipril, and simvastatin in healthy volunteers and with
or without coadministration of hydrochlorothiazide and torsemide in
patients with type 2 diabetes (see
Figure 1). The observed increases in overall exposure (AUC) of empagliflozin
following coadministration with gemfibrozil, rifampicin, or probenecid
are not clinically relevant. In subjects with normal renal function,
coadministration of empagliflozin with probenecid resulted in a 30%
decrease in the fraction of empagliflozin excreted in urine without
any effect on 24-hour urinary glucose excretion. The relevance of
this observation to patients with renal impairment is unknown.

SPL UNCLASSIFIED SECTION
Linagliptin
SPL UNCLASSIFIED SECTION
In vitro Assessment of
Drug Interactions
Linagliptin is a weak to moderate inhibitor
of CYP isozyme CYP3A4, but does not inhibit other CYP isozymes and
is not an inducer of CYP isozymes, including CYP1A2, 2A6, 2B6, 2C8,
2C9, 2C19, 2D6, 2E1, and 4A11.
Linagliptin is a P-glycoprotein (P-gp) substrate,
and inhibits P-gp mediated transport of digoxin at high concentrations.
Based on these results and
in vivo drug interaction
studies, linagliptin is considered unlikely to cause interactions
with other P-gp substrates at therapeutic concentrations.
SPL UNCLASSIFIED SECTION
In vivo Assessment of
Drug Interactions
Strong inducers of CYP3A4 or P-gp (e.g.,
rifampin) decrease exposure to linagliptin to subtherapeutic and likely
ineffective concentrations. For patients requiring use of such drugs,
an alternative to linagliptin is strongly recommended.
In
vivo studies indicated evidence of a low propensity for causing
drug interactions with substrates of CYP3A4, CYP2C9, CYP2C8, P-gp
and organic cationic transporter (OCT). No dose adjustment of linagliptin
is recommended based on results of the described pharmacokinetic studies.

and linagliptin to evaluate carcinogenesis, mutagenesis, or impairment
of fertility. General toxicity studies in rats up to 13 weeks were
performed with the combined components. These studies indicated that
no additive toxicity is caused by the combination of empagliflozin
and linagliptin.
SPL UNCLASSIFIED SECTION
Empagliflozin
Carcinogenesis was evaluated in 2-year studies conducted in CD-1
mice and Wistar rats. Empagliflozin did not increase the incidence
of tumors in female rats dosed at 100, 300, or 700 mg/kg/day (up to
72 times the exposure from the maximum clinical dose of 25 mg). In
male rats, hemangiomas of the mesenteric lymph node were increased
significantly at 700 mg/kg/day or approximately 42 times the exposure
from a 25 mg clinical dose. Empagliflozin did not increase the incidence
of tumors in female mice dosed at 100, 300, or 1000 mg/kg/day (up
to 62 times the exposure from a 25 mg clinical dose). Renal tubule
adenomas and carcinomas were observed in male mice at 1000 mg/kg/day,
which is approximately 45 times the exposure of the maximum clinical
dose of 25 mg. These tumors may be associated with a metabolic pathway
predominantly present in the male mouse kidney.
Empagliflozin was not mutagenic or clastogenic
with or without metabolic activation in the
in vitro Ames bacterial mutagenicity assay, the
in vitro L5178Y tk
+/- mouse lymphoma cell assay,
and an
in vivo micronucleus assay in rats.
Empagliflozin had no effects
on mating, fertility or early embryonic development in treated male
or female rats up to the high dose of 700 mg/kg/day (approximately
155 times the 25 mg clinical dose in males and females, respectively).
SPL UNCLASSIFIED SECTION
Linagliptin
Linagliptin did not increase the incidence of tumors in male and
female rats in a 2-year study at doses of 6, 18, and 60 mg/kg. The
highest dose of 60 mg/kg is approximately 418 times the clinical dose
of 5 mg/day based on AUC exposure. Linagliptin did not increase the
incidence of tumors in mice in a 2-year study at doses up to 80 mg/kg
(males) and 25 mg/kg (females), or approximately 35- and 270-times
the clinical dose based on AUC exposure. Higher doses of linagliptin
in female mice (80 mg/kg) increased the incidence of lymphoma at approximately
215-times the clinical dose based on AUC exposure.
Linagliptin was not mutagenic or clastogenic
with or without metabolic activation in the Ames bacterial mutagenicity
assay, a chromosomal aberration test in human lymphocytes, and an
in vivo micronucleus assay.
In fertility studies in rats, linagliptin
had no adverse effects on early embryonic development, mating, fertility,
or bearing live young up to the highest dose of 240 mg/kg (approximately
943-times the clinical dose based on AUC exposure).

Add-on Combination Therapy with Metformin
A total of 686 patients with type 2 diabetes
participated in a double-blind, active-controlled study to evaluate
the efficacy and safety of empagliflozin 10 mg or 25 mg in combination
with linagliptin 5 mg compared to the individual components.
Patients with type 2 diabetes
inadequately controlled on at least 1500 mg of metformin per day entered
a single-blind placebo run-in period for 2 weeks. At the end of the
run-in period, patients who remained inadequately controlled and had
an HbA1c between 7 and 10.5% were randomized 1:1:1:1:1 to one of 5
active-treatment arms of empagliflozin 10 mg or 25 mg, linagliptin
5 mg, or linagliptin 5 mg in combination with 10 mg or 25 mg empagliflozin
as a fixed dose combination tablet.
At Week 24, empagliflozin 10 mg or 25 mg
used in combination with linagliptin 5 mg provided statistically significant
improvement in HbA1c (p-value <0.0001) and FPG (p-value <0.001)
compared to the individual components in patients who had been inadequately
controlled on metformin (see
Table 5,
Figure 3). Treatment with GLYXAMBI 25 mg/5 mg
or GLYXAMBI 10 mg/5 mg daily also resulted in a statistically significant
reduction in body weight compared to linagliptin 5 mg (p-value <0.0001).
There was no statistically significant difference compared to empagliflozin
alone.

14.2 Empagliflozin Cardiovascular Outcome Study in Patients with Type 2 Diabetes Mellitus and Atherosclerotic Cardiovascular Disease
SPL UNCLASSIFIED SECTION
Empagliflozin is indicated to reduce the
risk of cardiovascular death in adults with type 2 diabetes mellitus
and established cardiovascular disease. However, the effectiveness
of GLYXAMBI on reducing the risk of cardiovascular death in adults
with type 2 diabetes mellitus and established cardiovascular disease
has not been established. The effect of empagliflozin on cardiovascular
risk in adult patients with type 2 diabetes and established, stable,
atherosclerotic cardiovascular disease is presented below.
The EMPA-REG OUTCOME study, a
multicenter, multi-national, randomized, double-blind parallel group
trial compared the risk of experiencing a major adverse cardiovascular
event (MACE) between empagliflozin and placebo when these were added
to and used concomitantly with standard of care treatments for diabetes
and atherosclerotic cardiovascular disease. Coadministered antidiabetic
medications were to be kept stable for the first 12 weeks of the trial.
Thereafter, antidiabetic and atherosclerotic therapies could be adjusted,
at the discretion of investigators, to ensure participants were treated
according to the standard care for these diseases.
A total of 7020 patients were treated (empagliflozin
10 mg = 2345; empagliflozin 25 mg = 2342; placebo = 2333) and followed
for a median of 3.1 years. Approximately 72% of the study population
was Caucasian, 22% was Asian, and 5% was Black. The mean age was 63
years and approximately 72% were male.
All patients in the study had inadequately
controlled type 2 diabetes mellitus at baseline (HbA1c greater than
or equal to 7%). The mean HbA1c at baseline was 8.1% and 57% of participants
had diabetes for more than 10 years. Approximately 31%, 22% and 20%
reported a past history of neuropathy, retinopathy and nephropathy
to investigators respectively and the mean eGFR was 74 mL/min/1.73
m
2. At baseline, patients were treated
with one (~30%) or more (~70%) antidiabetic medications including
metformin (74%), insulin (48%), sulfonylurea (43%) and dipeptidyl
peptidase-4 inhibitor (11%).
All patients had established atherosclerotic
cardiovascular disease at baseline including one (82%) or more (18%)
of the following; a documented history of coronary artery disease
(76%), stroke (23%) or peripheral artery disease (21%). At baseline,
the mean systolic blood pressure was 136 mmHg, the mean diastolic
blood pressure was 76 mmHg, the mean LDL was 86 mg/dL, the mean HDL
was 44 mg/dL, and the mean urinary albumin to creatinine ratio (UACR)
was 175 mg/g. At baseline, approximately 81% of patients were treated
with renin angiotensin system inhibitors, 65% with beta-blockers,
43% with diuretics, 77% with statins, and 86% with antiplatelet agents
(mostly aspirin).
The
primary endpoint in EMPA-REG OUTCOME was the time to first occurrence
of a Major Adverse Cardiac Event (MACE). A major adverse cardiac event
was defined as occurrence of either a cardiovascular death or a nonfatal
myocardial infarction (MI) or a nonfatal stroke. The statistical analysis
plan had pre-specified that the 10 and 25 mg doses would be combined.
A Cox proportional hazards model was used to test for non-inferiority
against the pre-specified risk margin of 1.3 for the hazard ratio
of MACE and superiority on MACE if non-inferiority was demonstrated.
Type-1 error was controlled across multiples tests using a hierarchical
testing strategy.
Empagliflozin
significantly reduced the risk of first occurrence of primary composite
endpoint of cardiovascular death, non-fatal myocardial infarction,
or non-fatal stroke (HR: 0.86; 95% CI 0.74, 0.99). The treatment effect
was due to a significant reduction in the risk of cardiovascular death
in subjects randomized to empagliflozin (HR: 0.62; 95% CI 0.49, 0.77),
with no change in the risk of non-fatal myocardial infarction or non-fatal
stroke (see
Table 6 and
Figure 4 and
5). Results for the
10 mg and 25 mg empagliflozin doses were consistent with results for
the combined dose groups.

The efficacy of empagliflozin on cardiovascular
death was generally consistent across major demographic and disease
subgroups.
Vital status
was obtained for 99.2% of subjects in the trial. A total of 463 deaths
were recorded during the EMPA-REG OUTCOME trial. Most of these deaths
were categorized as cardiovascular deaths. The non-cardiovascular
deaths were only a small proportion of deaths, and were balanced between
the treatment groups (2.1% in patients treated with empagliflozin,
and 2.4% of patients treated with placebo).
14.3 Linagliptin Cardiovascular Safety Trial
SPL UNCLASSIFIED SECTION
The cardiovascular risk of linagliptin was evaluated in CARMELINA,
a multi-national, multi-center, placebo-controlled, double-blind,
parallel group trial comparing linagliptin (N=3494) to placebo (N=3485)
in adult patients with type 2 diabetes mellitus and a history of established
macrovascular and/or renal disease. The trial compared the risk of
major adverse cardiovascular events (MACE) between linagliptin and
placebo when these were added to standard of care treatments for diabetes
and other cardiovascular risk factors. The trial was event driven,
the median duration of follow-up was 2.2 years and vital status was
obtained for 99.7% of patients.
Patients were eligible to enter the trial
if they were adults with type 2 diabetes, with HbA1c of 6.5% to 10%,
and had either albuminuria and previous macrovascular disease (39%
of enrolled population), or evidence of impaired renal function by
eGFR and Urinary Albumin Creatinine Ratio (UACR) criteria (42% of
enrolled population), or both (18% of enrolled population).
At baseline the mean age was
66 years and the population was 63% male, 80% Caucasian, 9% Asian,
and 6% Black. Mean HbA1c was 8.0% and mean duration of type 2 diabetes
mellitus was 15 years. The trial population included 17% patients
≥75 years of age and 62% patients with renal impairment defined as
eGFR <60 mL/min/1.73 m
2. The mean eGFR
was 55 mL/min/1.73 m
2 and 27% of patients
had mild renal impairment (eGFR 60 to 90 mL/min/1.73 m
2), 47% of patients had moderate renal impairment (eGFR
30 to <60 mL/min/1.73 m
2) and 15% of
patients had severe renal impairment (eGFR <30 mL/min/1.73 m
2). Patients were taking at least one antidiabetic
drug (97%), and the most common were insulin and analogues (57%),
metformin (54%) and sulfonylurea (32%). Patients were also taking
antihypertensives (96%), lipid lowering drugs (76%) with 72% on statin,
and aspirin (62%).
The primary endpoint, MACE, was the time to first occurrence of one
of three composite outcomes which included cardiovascular death, nonfatal
myocardial infarction or nonfatal stroke. The study was designed as
a non-inferiority trial with a pre-specified risk margin of 1.3 for
the hazard ratio of MACE.
The results of CARMELINA, including the contribution of each component
to the primary composite endpoint, are shown in Table 7. The estimated
hazard ratio for MACE associated with linagliptin relative to placebo
was 1.02 with a 95% confidence interval of (0.89, 1.17). The upper
bound of this confidence interval, 1.17, excluded the risk margin
of 1.3. The Kaplan-Meier curve depicting time to first occurrence
of MACE is shown in Figure 6.

Tablets
This Medication Guide has been approved
by the U.S. Food and Drug Administration.
Revised: July 2019
What is the most important information I should
know about GLYXAMBI?
Serious side effects can happen to
people taking GLYXAMBI,
including:
Inflammation of the pancreas (pancreatitis) which may be severe and lead to death. Certain medical problems
make you more likely to get pancreatitis.
Before
you start taking GLYXAMBI, tell your doctor if you have ever had:
inflammation of your pancreas (pancreatitis)
a history of alcoholism
stones in your gallbladder (gallstones)
high blood triglyceride levels
Stop taking GLYXAMBI
and call your doctor right away if you have pain in your stomach area
(abdomen) that is severe and will not go away. The pain may be felt
going from your abdomen to your back. The pain may happen with or
without vomiting. These may be symptoms of pancreatitis.
Heart failure. Heart failure means your heart
does not pump blood well enough.
Before you start
taking GLYXAMBI, tell your doctor if you have ever had heart
failure or have problems with your kidneys. Contact your doctor right
away if you have any of the following symptoms:
increasing shortness of breath or trouble breathing, especially
when you lie down
swelling or fluid retention, especially in the feet, ankles
or legs
an unusually fast increase in weight
unusual tiredness
These may be symptoms of heart failure.
