CLINICAL PHARMACOLOGY SECTION
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Sunitinib is a small molecule that inhibits multiple receptor tyrosine kinases
(RTKs), some of which are implicated in tumor growth, pathologic angiogenesis,
and metastatic progression of cancer. Sunitinib was evaluated for its
inhibitory activity against a variety of kinases (>80 kinases) and was
identified as an inhibitor of platelet-derived growth factor receptors (PDGFRα
and PDGFRβ), vascular endothelial growth factor receptors (VEGFR1, VEGFR2, and
VEGFR3), stem cell factor receptor (KIT), Fms-like tyrosine kinase-3 (FLT3),
colony stimulating factor receptor Type 1 (CSF-1R), and the glial cell-line
derived neurotrophic factor receptor (RET). Sunitinib inhibition of the
activity of these RTKs has been demonstrated in biochemical and cellular
assays, and inhibition of function has been demonstrated in cell proliferation
assays. The primary metabolite exhibits similar potency compared to sunitinib
in biochemical and cellular assays.
Sunitinib inhibited the phosphorylation of multiple RTKs (PDGFRβ, VEGFR2, KIT)
in tumor xenografts expressing RTK targets in vivo and demonstrated inhibition
of tumor growth or tumor regression and/or inhibited metastases in some
experimental models of cancer. Sunitinib demonstrated the ability to inhibit
growth of tumor cells expressing dysregulated target RTKs (PDGFR, RET, or KIT)
in vitro and to inhibit PDGFRβ- and VEGFR2-dependent tumor angiogenesis in
vivo.
12.2 Pharmacodynamics
Exposure-Response Relationship
Based on population pharmacokinetic/pharmacodynamic analyses, there were
relationships between changes in different pharmacodynamic endpoints (i.e.,
safety and efficacy endpoints) over time and sunitinib plasma exposures.
Cardiac Electrophysiology
Sunitinib malate can cause QT interval prolongation in a dose-dependent
manner, which may lead to an increased risk for ventricular arrhythmias
including Torsade de Pointes [see Warnings and Precautions (5.3)].
12.3 Pharmacokinetics
The pharmacokinetics of sunitinib and sunitinib malate have been evaluated in
healthy subjects and in patients with solid tumors.
Sunitinib AUC and Cmax increase proportionately over a dose range of 25 mg to
100 mg (0.5 to 2 times the approved RDD of 50 mg). The pharmacokinetics were
similar in healthy subjects and in patients with a solid tumor, including
patients with GIST and RCC. No significant changes in the pharmacokinetics of
sunitinib or the primary active metabolite were observed with repeated daily
administration or with repeated cycles. With repeated daily administration,
sunitinib accumulates 3- to 4-fold while the primary metabolite accumulates 7-
to 10-fold. Steady-state concentrations of sunitinib and its primary active
metabolite are achieved within 10 to 14 days. By Day 14, combined plasma
concentrations of sunitinib and its active metabolite ranged from 63 to 101
ng/mL.
Absorption
Following oral administration of sunitinib, the time to maximum plasma
concentration (Tmax) ranged from 6 to 12 hours.
Effect of Food
The administration of a single dose of sunitinib malate 50 mg with a high-fat,
high-calorie meal (consisting of approximately 150 protein calories and 500 to
600 fat calories) in healthy subjects had no clinically significant effect on
sunitinib malate or active metabolites exposure.
Distribution
The apparent volume of distribution (Vd/F) for sunitinib is 2230 L. Binding of
sunitinib and its primary active metabolite to human plasma protein in vitro
is 95% and 90%, respectively, with no concentration dependence in the range of
100 to 4,000 ng/mL.
Elimination
Following administration of a single oral dose in healthy subjects, the
terminal half-lives of sunitinib and its primary active metabolite are
approximately 40 to 60 hours and 80 to 110 hours, respectively. Sunitinib
total oral clearance (CL/F) ranged from 34 to 62 L/h with an interpatient
variability of 40%.
Metabolism
Sunitinib is metabolized primarily by CYP3A4 to its primary active metabolite,
which is further metabolized by CYP3A4. The primary active metabolite
comprises 23% to 37% of the total exposure. After a radiolabeled dose,
sunitinib and its active metabolite were the major compounds identified in
plasma, accounting for 92% of radioactivity.
Excretion
After a radiolabeled dose of sunitinib, approximately 61% of the dose was
recovered in feces and 16% in urine.
Sunitinib and its primary active metabolite were the major compounds
identified in urine and feces, representing 86% and 74% of radioactivity,
respectively.
Specific Populations
No clinically significant differences in the pharmacokinetics of sunitinib or
the primary active metabolite were observed based on age (18 to 84 years),
body weight (34 to 168 kg), race (White, Black, or Asian), sex, Eastern
Cooperative Oncology Group (ECOG) score, mild (Child-Pugh Class A) or moderate
(Child-Pugh Class B) hepatic impairment.
Patients with Renal Impairment
No clinically significant differences in the pharmacokinetics of sunitinib or
its active metabolite were predicted or observed in patients with mild (CLcr
50 to 80 mL/min), moderate (CLcr 30 to <50 mL/min), or severe (CLcr <30
mL/min) renal impairment who are not on dialysis, compared to patients with
normal renal function (CLcr >80 mL/min). Although sunitinib was not eliminated
through hemodialysis, the sunitinib systemic exposure was 47% lower in
patients with end stage renal disease (ESRD) on hemodialysis compared to
patients with normal renal function.
Drug Interaction Studies
Clinical Studies
Effect of strong CYP3A4 inhibitors on sunitinib: Co-administration of a single
sunitinib malate dose with ketoconazole (strong CYP3A4 inhibitor) increased
the combined sunitinib and its active metabolite Cmax and AUC0-inf by 49% and
51%, respectively, in healthy subjects.
Effect of strong CYP3A4 inducers on sunitinib: Co-administration of a single
sunitinib malate dose with rifampin (strong CYP3A4 inducer) reduced the
combined sunitinib and its active metabolite Cmax and AUC0-inf by 23% and 46%,
respectively in healthy subjects.
In Vitro Studies
In vitro studies in human hepatocytes and microsomes indicated that sunitinib
and the primary active metabolite do not induce CYP1A2, CYP2E1, and CYP3A4/5,
or inhibit CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1,
CYP3A4/5, and CYP4A9/11 at clinically relevant concentrations.

5 WARNINGS AND PRECAUTIONS
5.1 Hepatotoxicity
Sunitinib malate can cause severe hepatotoxicity, resulting in liver failure or death. In the pooled safety population, liver failure occurred in <1% of patients in clinical trials. Liver failure include jaundiced, elevated transaminases and/or hyperbilirubinemia in conjunction with encephalopathy, coagulopathy, and/or renal failure.
Monitor liver function tests (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and bilirubin) at baseline, during each cycle, and as clinically indicated. Interrupt sunitinib malate for Grade 3 hepatotoxicity until resolution to Grade ≤1 or baseline, then resume sunitinib malate at a reduced dose.
Discontinue sunitinib malate in patients with Grade 4 hepatotoxicity, in patients without resolution of Grade 3 hepatotoxicity, in patients who subsequently experience severe changes in liver function tests and in patients who have other signs and symptoms of liver failure. Safety in patients with ALT or AST >2.5 x upper limit of normal (ULN) or with >5 x ULN and liver metastases has not been established.
5.2 Cardiovascular Events
Cardiovascular events, including heart failure, cardiomyopathy, myocardial ischemia, and myocardial infarction, some of which were fatal, have been reported.
In pooled safety population, 3% of patients experienced heart failure; 71% of
the patients with heart failure were reported as recovered. Fatal cardiac
failure was reported in <1% of patients.
In the adjuvant treatment of RCC study, 11 patients experienced Grade 2
decreased ejection fraction (left ventricular ejection fraction [LVEF] 40% to
50% and a 10% to 19% decrease from baseline). In 3 of these 11 patients, the
ejection fractions arm did not return to ≥50% or baseline by the time of last
measurement. No patients who received sunitinib malate were diagnosed with
CHF.
Patients who presented with cardiac events within 12 months prior to sunitinib malate administration, such as myocardial infarction (including severe/unstable angina), coronary/peripheral artery bypass graft, symptomatic CHF, cerebrovascular accident or transient ischemic attack, or pulmonary embolism were excluded from sunitinib malate clinical studies. Patients with prior anthracycline use or cardiac radiation were also excluded from some studies. It is unknown whether patients with these concomitant conditions may be at a higher risk of developing left ventricular dysfunction.
Consider monitoring LVEF at baseline and periodically as clinically indicated. Carefully monitor patients for clinical signs and symptoms of congestive heart failure (CHF). Discontinue sunitinib malate in patients who experience clinical manifestations of CHF. Interrupt sunitinib malate and/or reduce the dose in patients without clinical evidence of CHF who have an ejection fraction of greater than 20% but less than 50% below baseline or below the lower limit of normal if baseline ejection fraction was not obtained.
5.3 QT Interval Prolongation and Torsade de Pointes
Sunitinib malate can cause QT interval prolongation in a dose-dependent
manner, which may lead to an increased risk for ventricular arrhythmias
including Torsade de Pointes.Torsade de Pointes was observed in <0.1% of
patients.
Monitor patients who are at higher risk of developing QT interval
prolongation, including patients with a history of QT interval prolongation,
patients who are taking antiarrhythmics, or patients with relevant pre-
existing cardiac disease, bradycardia, or electrolyte disturbances. Consider
periodic monitoring of electrocardiograms and electrolytes (i.e., magnesium,
potassium) during treatment with sunitinib malate.
Monitor QT interval more frequently when sunitinib malate is concomitantly administered with strong CYP3A4 inhibitors or drugs known to prolong QT interval. Consider dose reducing sunitinib malate [see Dosage and Administration (2.5), Drug Interactions (7.2)].
5.4 Hypertension
In the pooled safety population, 29% of patients experienced hypertension. Grade 3 hypertension was reported in 7% of patients, and Grade 4 hypertension was reported in 0.2%.
Monitor blood pressure at baseline and as clinically indicated. Initiate and/or adjust antihypertensive therapy as appropriate. In cases of Grade 3 hypertension, withhold sunitinib malate until resolution to Grade ≤1 or baseline, then resume sunitinib malate at a reduced dose. Discontinue sunitinib malate in patients with who develop Grade 4 hypertension.
5.5 Hemorrhagic Events and Viscus Perforation
Hemorrhagic events, some of which were fatal, have involved the gastrointestinal tract, respiratory tract, tumor, urinary tract, and brain. In the pooled safety population, 30% of patients experienced hemorrhagic events, including Grade 3 or 4 in 4.2% of patients. Epistaxis was the most common hemorrhagic event and gastrointestinal hemorrhage was the most common Grade 3-5 event.
Tumor-related hemorrhage was observed in patients treated with sunitinib
malate. These events may occur suddenly, and in the case of pulmonary tumors,
may present as severe and life-threatening hemoptysis or pulmonary hemorrhage.
Pulmonary hemorrhage, some with a fatal outcome, was observed in patients
treated with sunitinib malate for metastatic RCC, GIST, and metastatic lung
cancer. Sunitinib malate is not approved for use in patients with lung cancer.
Serious, sometimes fatal, gastrointestinal complications including
gastrointestinal perforation, have been reported in patients with intra-
abdominal malignancies treated with sunitinib malate.
Include serial complete blood counts (CBCs) and physical examinations with the
clinical assessment of hemorrhagic events. Interrupt sunitinib malate for
Grade 3 or 4 hemorrhagic events until resolution to Grade ≤1 or baseline, then
resume sunitinib malate at a reduced dose.
Discontinue sunitinib malate in patients without resolution of Grade 3 or 4 hemorrhagic events.
5.6 Tumor Lysis Syndrome (TLS)
Tumor Lysis Syndrome (TLS), some fatal, occurred in clinical trials and has been reported in postmarketing experience, primarily in patients with RCC or GIST. Patients generally at risk of TLS are those with high tumor burden prior to treatment. Monitor these patients for TLS and manage as appropriate.
5.7 Thrombotic Microangiopathy (TMA)
Thrombotic Microangiopathy (TMA), including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, sometimes leading to renal failure or a fatal outcome, occurred in clinical trials and in postmarketing experience of sunitinib malate as monotherapy and administered in combination with bevacizumab. Sunitinib malate is not approved for use in combination with bevacizumab.
Discontinue sunitinib malate in patients developing TMA. Reversal of the effects of TMA has been observed after sunitinib malate was discontinued.
5.8 Proteinuria
Proteinuria and nephrotic syndrome have been reported. Some of these cases have resulted in renal failure and fatal outcomes.
Monitor patients for the development or worsening of proteinuria. Perform baseline and periodic urinalyses during treatment, with follow up measurement of 24-hour urine protein as clinically indicated. Interrupt sunitinib malate and dose reduce for 24-hour urine protein of 3 or more grams. Discontinue sunitinib malate for patients with nephrotic syndrome or repeat episodes of 24-hour urine protein of 3 or more grams despite dose reductions. The safety of continued sunitinib malate treatment in patients with moderate to severe proteinuria has not been evaluated.
5.9 Dermatologic Toxicities
Severe cutaneous adverse reactions have been reported, including erythema
multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal
necrolysis (TEN), some of which were fatal. Permanently discontinue sunitinib
malate for these severe cutaneous adverse reactions.
Necrotizing fasciitis, including fatal cases, has been reported in patients
treated with sunitinib malate, including of the perineum and secondary to
fistula formation. Discontinue sunitinib malate in patients who develop
necrotizing fasciitis.
5.10 Reversible Posterior Leukoencephalopathy Syndrome (RPLS)
Reversible posterior leukoencephalopathy syndrome (RPLS) has been reported in <1% of patients, some of which were fatal. Patients can present with hypertension, headache, decreased alertness, altered mental functioning, and visual loss, including cortical blindness. Magnetic resonance imaging is necessary to confirm the diagnosis. Discontinue sunitinib malate in patients developing RPLS.
5.11 Thyroid Dysfunction
Hyperthyroidism, some followed by hypothyroidism, have been reported in clinical trials and through postmarketing experience of sunitinib malate.
Monitor thyroid function at baseline, periodically during treatment and as clinically indicated. Monitor patients closely for signs and symptoms of thyroid dysfunction, including hypothyroidism, hyperthyroidism, and thyroiditis, during treatment with sunitinib malate. Initiate and/or adjust therapies for thyroid dysfunction as appropriate.
5.12 Hypoglycemia
Sunitinib malate can result in symptomatic hypoglycemia, which may lead to loss of consciousness, or require hospitalization. In the pooled safety population, hypoglycemia occurred in 2% of the patients treated with sunitinib malate. Hypoglycemia has occurred in clinical trials in 2% of the patients treated with sunitinib malate for advanced RCC (Study 3) and GIST (Study 1) (n=577) and in approximately 10% of the patients treated with sunitinib malate for pNET (Study 6) (n=83). For patients being treated with sunitinib malate for pNET, pre-existing abnormalities in glucose homeostasis were not present in all patients who experienced hypoglycemia. Reductions in blood glucose levels may be worse in patients with diabetes.
Check blood glucose levels at baseline, regularly during treatment, as clinically indicated and after discontinuation of sunitinib malate. In patients with diabetes, assess if antidiabetic therapies need to be adjusted to minimize the risk of hypoglycemia.
5.13 Osteonecrosis of the Jaw (ONJ)
Osteonecrosis of the Jaw (ONJ) occurred in patients treated with sunitinib malate. Concomitant exposure to other risk factors, such as bisphosphonates or dental disease/invasive dental procedures, may increase the risk of ONJ. Perform an oral examination prior to initiation of sunitinib malate and periodically during sunitinib malate therapy. Advise patients regarding good oral hygiene practices. Withhold sunitinib malate treatment for at least 3 weeks prior to scheduled dental surgery or invasive dental procedures, if possible. Withhold sunitinib malate for development of ONJ until complete resolution. The safety of resumption of sunitinib malate after resolution of osteonecrosis of the jaw has not been established.
5.14 Impaired Wound Healing
Impaired wound healing has been reported in patients who received sunitinib malate [see Adverse Reactions (6.2)].
Withhold sunitinib malate for at least 3 weeks prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of sunitinib malate after resolution of wound healing complications has not been established.
5.15 Embryo-Fetal Toxicity
Based on findings from animal studies and its mechanism of action, sunitinib
malate can cause fetal harm when administered to pregnant woman.
Administration of sunitinib to pregnant rats and rabbits during the period of
organogenesis resulted in teratogenicity at approximately 5.5 and 0.3 times
the combined systemic exposure [combined area under the curve (AUC) of sunitinib plus its active metabolite] in patients administered the recommended
daily dose (RDD) of 50 mg, respectively.
Advise pregnant women of the potential risk to a fetus. Advise females of
reproductive potential to use effective contraception during treatment with
sunitinib malate and for 4 weeks following the final dose [see Use in Specific Populations (8.1, 8.3)].
DRUG INTERACTIONS SECTION
Highlight: * CYP3A4 Inhibitors: Consider dose reduction of sunitinib malate when administered with strong CYP3A4 inhibitors. (7.1)
- CYP3A4 Inducers: Consider dose increase of sunitinib malate when administered with strong CYP3A4 inducers. (7.1)
7 DRUG INTERACTIONS
7.1 Effect of Other Drugs on Sunitinib Malate
Strong CYP3A4 Inhibitors
Co-administration with strong CYP3A4 inhibitors may** increase** sunitinib
plasma concentrations [see Clinical Pharmacology (12.3)]. Select an alternate
concomitant medication with no or minimal enzyme inhibition potential.
Consider a dose reduction for sunitinib malate when it is co-administered with
strong CYP3A4 inhibitors [see Dosage and Administration (2.5)].
Strong CYP3A4 Inducers
Co-administration with strong CYP3A4 inducers maydecrease sunitinib
plasma concentrations [see Clinical Pharmacology (12.3)]. Select an alternate
concomitant medication with no or minimal enzyme induction potential. Consider
a dose increase for sunitinib malate when it must be co-administered with
CYP3A4 inducers [see Dosage and Administration (2.5)].
7.2 Drugs that Prolong QT Interval
Sunitinib malate is associated with QTc interval prolongation [see Warnings and Precautions (5.3), Clinical Pharmacology (12.2)]. Monitor the QT interval with ECGs more frequently in patients who require treatment with concomitant medications known to prolong the QT interval.
USE IN SPECIFIC POPULATIONS SECTION
Highlight: * Lactation: Advise not to breastfeed. (8.2)
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
Based on animal reproduction studies and its mechanism of action, sunitinib
malate can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data in pregnant women
to inform a drug-associated risk. In animal developmental and reproductive
toxicology studies, oral administration of sunitinib to pregnant rats and
rabbits throughout organogenesis resulted in teratogenicity (embryolethality,
craniofacial and skeletal malformations) at 5.5 and 0.3 times the combined AUC
(the combined systemic exposure of sunitinib plus its active metabolite) in
patients administered the recommended daily doses (RDD) of 50 mg, respectively
(see Data). Advise females of reproductive potential of the potential risk to
a fetus.
The estimated background risk of major birth defects and miscarriage for the
indicated populations are unknown. All pregnancies have a background risk of
birth defect, loss, or other adverse outcomes. In the U.S. general population,
the estimated background risk of major birth defects and miscarriages in
clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data
Animal Data
In a female fertility and early embryonic development study, female rats were
administered oral sunitinib (0.5, 1.5, 5 mg/kg/day) for 21 days prior to
mating and for 7 days after mating. Embryolethality was observed at 5
mg/kg/day (approximately 5 times the combined AUC in patients administered the
RDD of 50 mg).
In embryo-fetal developmental toxicity studies, oral sunitinib was
administered to pregnant rats (0.3, 1.5, 3, 5 mg/kg/day) and rabbits (0.5, 1,
5, 20 mg/kg/day) during the period of organogenesis. In rats, embryolethality
and skeletal malformations of the ribs and vertebrae were observed at the dose
of 5 mg/kg/day (approximately 5.5 times the combined AUC in patients
administered the RDD of 50 mg). No adverse fetal effects were observed in rats
at doses ≤3 mg/kg/day (approximately 2 times the combined AUC in patients
administered the RDD of 50 mg). In rabbits, embryolethality was observed at 5
mg/kg/day (approximately 3 times the combined AUC in patients administered the
RDD of 50 mg), and craniofacial malformations (cleft lip and cleft palate)
were observed at ≥1 mg/kg/day (approximately 0.3 times the combined AUC in
patients administered the RDD of 50 mg).
Sunitinib (0.3, 1, 3 mg/kg/day) was evaluated in a pre- and postnatal
development study in pregnant rats. Maternal body weight gains were reduced
during gestation and lactation at doses ≥1 mg/kg/day (approximately 0.5 times
the combined AUC in patients administered the RDD of 50 mg). At 3 mg/kg/day
(approximately 2 times the combined AUC in patients administered the RDD of 50
mg), reduced neonate body weights were observed at birth and persisted in the
offspring of both sexes during the preweaning period and in males during
postweaning period. No adverse developmental effects were observed at doses ≤1
mg/kg/day.
8.2 Lactation
There is no information regarding the presence of sunitinib and its
metabolites in human milk. Sunitinib and its metabolites were excreted in rat
milk at concentrations up to 12-fold higher than in plasma (see Data). Because
of the potential for serious adverse reactions in breastfed infants, advise
women not to breastfeed during treatment with sunitinib malate and for at
least 4 weeks after the last dose.
Data
Animal Data
In lactating female rats administered 15 mg/kg, sunitinib and its metabolites
were excreted in milk at concentrations up to 12-fold higher than in plasma.
8.3 Females and Males of Reproductive Potential
Sunitinib malate can cause fetal harm when administered to a pregnant woman
[see Use in Specific Populations (8.1)].
Pregnancy Testing
Verify pregnancy status of females of reproductive potential prior to
initiating treatment with sunitinib malate.
Contraception
Females
Advise females of reproductive potential to use effective contraception during
treatment with sunitinib malate and for at least 4 weeks after the last dose.
Males
Based on findings in animal reproduction studies, advise males with female
partners of reproductive potential to use effective contraception during
treatment with sunitinib malate and for 7 weeks after the last dose.
Infertility
Based on findings in animals, sunitinib malate may impair male and female
fertility [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
The safety and effectiveness of sunitinib malate in pediatric patients have
not been established. Safety and pharmacokinetics of sunitinib were assessed
in an open-label study (NCT00387920) in pediatric patients 2 years to <17
years of age (n=29) with refractory solid tumors. In addition, efficacy,
safety and pharmacokinetics of sunitinib was assessed in another open-label
study (NCT01462695) in pediatric patients 2 years to <17 years of age (n=27)
with high-grade glioma or ependymoma. The maximum tolerated dose (MTD)
normalized for body surface area (BSA) was lower in pediatric patients
compared to adults. Sunitinib was poorly tolerated in pediatric patients. The
occurrence of dose-limiting cardiotoxicity prompted an amendment of the
NCT00387920 study to exclude patients with previous exposure to anthracyclines
or cardiac radiation. No responses were reported in patients in either of the
trials.
Apparent clearance and volume of distribution normalized for BSA for sunitinib
and its active major metabolite were lower in pediatrics as compared to
adults.
The effect on open tibial growth plates in pediatric patients who received
sunitinib malate has not been adequately studied. See Juvenile Animal Toxicity
Data below.
Juvenile Animal Toxicity Data
Physeal dysplasia was present in cynomolgus monkeys with open growth plates
treated with sunitinib for ≥3 months (3 month dosing 2, 6, 12 mg/kg/day; 8
cycles of dosing 0.3, 1.5, 6 mg/kg/day) at doses that were >0.4 times the the
combined AUC (the combined systemic exposure of sunitinib plus its active
metabolite) in patients administered the RDD of 50 mg. The no-effect level
(NOEL) was 1.5 mg/kg/day in monkeys treated intermittently for 8 cycles, but
was not identified in monkeys treated continuously for 3 months. In developing
rats treated continuously for 3 months (1.5, 5, and 15 mg/kg) or 5 cycles
(0.3, 1.5, and 6 mg/kg/day), bone abnormalities consisted of thickening of the
epiphyseal cartilage of the femur and an increase of fracture of the tibia at
doses ≥5 mg/kg (approximately 10 times the combined AUC in patients
administered the RDD of 50 mg). Additionally, tooth caries were present in
rats at >5 mg/kg. The incidence and severity of physeal dysplasia were dose
related and reversible upon cessation of treatment; however, findings in the
teeth were not. In rats, the NOEL in bones was ≤2 mg/kg/day.
8.5 Geriatric Use
Of the 7527 patients with GIST, RCC (advanced and adjuvant), or pNET who
received sunitinib malate, 32% were 65 years and older, and 7% were 75 years
and older. Patients aged 65 years of age and older had a higher incidence of
Grade 3 or 4 adverse reactions (67%) than younger patients (60%).
In the GIST study, 73 (30%) of the patients who received sunitinib malate were
65 years and older. In the mRCC study, 152 (41%) of patients who received
sunitinib malate were 65 years and older. No overall differences in safety or
effectiveness were observed between these patients and younger patients.
In the pNET study, 22 (27%) of the patients who received sunitinib malate were
65 years and older. Clinical studies of sunitinib malate did not include
sufficient numbers of patients with pNET to determine if patients 65 years of
age and older respond differently than younger patients.
8.6 Hepatic Impairment
No dose adjustment is required in patients with mild or moderate (Child-Pugh Class A or B) hepatic impairment [see Clinical Pharmacology (12.3)]. Sunitinib malate was not studied in patients with severe (Child-Pugh Class C) hepatic impairment.
8.7 Renal Impairment
No dose adjustment is recommended in patients with mild (CLcr 50 to 80
mL/min), moderate (CLcr 30 to <50 mL/min), or severe (CLcr <30 mL/min) renal
impairment who are not on dialysis [see Clinical Pharmacology (12.3)].
No dose adjustment is recommended for patients with end-stage renal disease
(ESRD) on hemodialysis [see Clinical Pharmacology (12.3)].

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse
reaction rates observed in the clinical trials of a drug cannot be directly
compared to rates in the clinical trials of another drug and may not reflect
the rates observed in practice.
The pooled safety population described in the Warnings and Precautions reflect
exposure to sunitinib malate in 7527 patients with GIST, RCC (advanced and
adjuvant), or pNET. In this pooled safety population, the most common adverse
reactions (≥25%) were fatigue/asthenia, diarrhea, mucositis/stomatitis,
nausea, decreased appetite/anorexia, vomiting, abdominal pain, hand-foot
syndrome, hypertension, bleeding events, dysgeusia/altered taste, dyspepsia,
and thrombocytopenia.
Gastrointestinal Stromal Tumor
The safety of sunitinib malate was evaluated in Study 1, a randomized, double-
blind, placebo-controlled trial in which previously treated patients with GIST
received sunitinib malate 50 mg daily on Schedule 4/2 (n=202) or placebo
(n=102). Median duration of blinded study treatment was 2 cycles for patients
on sunitinib malate (mean: 3.0; range: 1-9) and 1 cycle (mean; 1.8; range:
1-6) for patients on placebo at the time of the interim analysis.
Permanent discontinuation due to an adverse reaction occurred in 7% of
patients in the sunitinib malate arm. Dose reductions occurred in 11% and dose
interruptions occurred in 29% of patients who received sunitinib malate.
Table 3 summarizes the adverse reactions for Study 1.

b Grade 4 laboratory abnormalities in patients on placebo included amylase (1%), lipase (1%), and hemoglobin (2%).
After an interim analysis, the study was unblinded and patients on the placebo arm were given the opportunity to receive open-label sunitinib malate [see Clinical Studies (14.1)]. For 241 patients randomized to the sunitinib malate arm, including 139 who received sunitinib malate in both the double-blind and open-label phases, the median duration of sunitinib malate treatment was 6 cycles (mean: 8.5; range: 1–44). For the 255 patients who ultimately received open-label sunitinib malate treatment, median duration of treatment was 6 cycles (mean: 7.8; range: 1–37) from the time of the unblinding.
Permanent discontinuation due to an adverse reaction occurred in 20% of patients who received sunitinib malate. Dosage interruption occurred in 46% and dose reduction occurred in 28% of patients who received sunitinib malate.
The most common Grade 3 or 4 adverse reactions in patients who received
sunitinib malate in the open-label phase were fatigue (10%), hypertension
(8%), asthenia (5%), diarrhea (5%), hand-foot syndrome (5%), nausea (4%),
abdominal pain (3%), anorexia (3%), mucositis (2%), vomiting (2%), and
hypothyroidism (2%).
Advanced Renal Cell Carcinoma
The safety of sunitinib malate was evaluated in Study 3, a double-blind,
active-controlled trial in which previously untreated patients with locally
advanced or metastatic RCC received sunitinib malate 50 mg daily on Schedule
4/2 (n=375) or interferon alfa 9 million International Units (MIU) (n=360).
The median duration of treatment was 11.1 months (range: 0.4 to 46.1) for
sunitinib malate treatment and 4.1 months (range: 0.1 to 45.6) for interferon
alfa treatment.
Permanent discontinuation due to an adverse reaction occurred in 20% of

Long-Term Safety in RCC
The long-term safety of sunitinib malate in patients with metastatic RCC was
analyzed across 9 completed clinical studies conducted in the first-line,
bevacizumab-refractory, and cytokine-refractory treatment settings.The
analysis included 5739 patients, of whom 807 (14%) were treated for at least 2
years and 365 (6%) for at least 3 years. Prolonged treatment with sunitinib
malate did not appear to be associated with new types of adverse
reactions.There appeared to be no increase in the yearly incidence of adverse
reactions at later time points.
Hypothyroidism increased during the second year of treatment with new cases
reported up to year 4.
Adjuvant Treatment of RCC
The safety of sunitinib malate was evaluated in S-TRAC, a randomized, double-
blind, placebo-controlled trial in which patients who had undergone
nephrectomy for RCC received sunitinib malate 50 mg daily on Schedule 4/2
(n=306) or placebo (n=304).The median duration of treatment was 12.4 months
(range: 0.13 to 14.9) for sunitinib malate and 12.4 months (range: 0.03 to
13.7) for placebo.
Permanent discontinuation due to an adverse reaction occurred in 28% of
patients in the sunitinib malate arm. Adverse reactions leading to permanent
discontinuation in >2% of patients include hand-foot syndrome and
fatigue/asthenia. Dosing interruptions occurred in 54% and dose reductions
occurred in 46% of patients who received sunitinib malate.

CLINICAL STUDIES SECTION
14 CLINICAL STUDIES
14.1 Gastrointestinal Stromal Tumor
Study 1
Study 1 (NCT#00075218) was a 2-arm, international, randomized, double-blind,
placebo-controlled trial of sunitinib malate in patients with GIST who had
disease progression during prior imatinib mesylate (imatinib) treatment or who
were intolerant of imatinib. The objective was to compare time-to-tumor
progression (TTP) in patients receiving sunitinib malate plus best supportive
care versus patients receiving placebo plus best supportive care. Other
objectives included progression-free survival (PFS), objective response rate
(ORR), and overall survival (OS). Patients were randomized (2:1) to receive
either 50 mg sunitinib malate or placebo orally, once daily, on Schedule 4/2
until disease progression or withdrawal from the study for another reason.
Treatment was unblinded at the time of disease progression. Patients
randomized to placebo were then offered crossover to open-label sunitinib
malate and patients randomized to sunitinib malate were permitted to continue
treatment per investigator judgment.
At the time of a prespecified interim analysis, the intent-to-treat (ITT)
population included 312 patients. Two hundred seven (207) patients were
randomized to the sunitinib malate arm and 105 patients were randomized to the
placebo arm. Demographics were comparable between the sunitinib malate and
placebo groups with regard to age (69% versus 72% <65 years for sunitinib
malate versus placebo, respectively), sex (male: 64% versus 61%), race (White:
88% both arms, Asian: 5% both arms, Black: 4% both arms, remainder not
reported), and performance status (ECOG 0: 44% versus 46%, ECOG 1: 55% versus
52%, and ECOG 2: 1% versus 2%). Prior treatment included surgery (94% versus
93%) and radiotherapy (8% versus 15%). Outcome of prior imatinib treatment was
also comparable between arms with intolerance (4% versus 4%), progression
within 6 months of starting treatment (17% versus 16%), or progression beyond
6 months (78% versus 80%) balanced.
The planned interim efficacy and safety analysis was performed after 149 TTP
events had occurred. There was a statistically significant advantage for
sunitinib malate over placebo in TTP, meeting the primary endpoint. Efficacy
results are summarized in Table 10 and the Kaplan-Meier curve for TTP is shown
in Figure 1.

The final ITT population enrolled in the double-blind treatment phase of the
study included 243 patients randomized to the sunitinib malate arm and 118
patients randomized to the placebo arm. After the primary endpoint was met at
the interim analysis, the study was unblinded, and patients on the placebo arm
were offered open-label sunitinib malate treatment. Ninety-nine (99) of the
patients initially randomized to placebo crossed over to receive sunitinib
malate in the open-label treatment phase. At the protocol specified final
analysis of OS, the median OS was 72.7 weeks for the sunitinib malate arm and
64.9 weeks for the placebo arm [hazard ratio (HR)=0.876, 95% confidence interval (CI) (0.679, 1.129)].
Study 2
Study 2 was an open-label, multi-center, single-arm, dose-escalation study
conducted in patients with GIST following progression on, or intolerance to
imatinib. Following identification of the recommended regimen (50 mg once
daily on Schedule 4/2), 55 patients in this study received the 50 mg dose of
sunitinib malate on treatment Schedule 4/2. Partial responses (PR) were
observed in 5 of 55 patients (9.1% PR rate; 95% CI: 3.0%, 20.0%).
14.2 Renal Cell Carcinoma
Treatment-Naïve
Study 3 (NCT#00083889) was a multi-center, international, randomized study
comparing single-agent sunitinib malate with interferon alfa was conducted in
patients with treatment-naïve RCC. The objective was to compare PFS in
patients receiving sunitinib malate versus patients receiving interferon alfa.
Other endpoints included ORR, OS, and safety. Seven hundred fifty (750)
patients were randomized (1:1) to receive either 50 mg sunitinib malate once
daily on Schedule 4/2 or to receive interferon alfa administered
subcutaneously at 9 million international units (MIU) 3 times a week. Patients
were treated until disease progression or withdrawal from the study.
The ITT population included 750 patients, 375 randomized to sunitinib malate
and 375 randomized to interferon alfa. Demographics were comparable between
the sunitinib malate and interferon alfa groups with regard to age (59% versus
67% <65 years for sunitinib malate versus interferon alfa, respectively), sex
(male: 71% versus 72%), race (White: 94% versus 91%, Asian: 2% versus 3%,
Black: 1% versus 2%, remainder not reported), and performance status (ECOG 0:
62% versus 61%, ECOG 1: 38% each arm, ECOG 2: 0 versus 1%). Prior treatment
included nephrectomy (91% versus 89%) and radiotherapy (14% each arm). The
most common site of metastases present at screening was the lung (78% versus
80%, respectively), followed by the lymph nodes (58% versus 53%, respectively)
and bone (30% each arm); the majority of the patients had multiple (2 or more)
metastatic sites at baseline (80% versus 77%, respectively).
There was a statistically significant advantage for sunitinib malate over
interferon alfa in the endpoint of PFS (see Table 11 and Figure 2). In the
prespecified stratification factors of lactate dehydrogenase (LDH) (>1.5 ULN
versus ≤1.5 ULN), ECOG performance status (0 versus 1), and prior nephrectomy
(yes versus no), the hazard ratio favored sunitinib malate over interferon
alfa. The ORR was higher in the sunitinib malate arm (see Table 11).

At the protocol-specified final analysis of OS, the median OS was 114.6 weeks
for the sunitinib malate arm and 94.9 weeks for the interferon alfa arm
(HR=0.821; 95% CI: 0.673, 1.001). The median OS for the interferon alfa arm
includes 25 patients who discontinued interferon alfa treatment because of
disease progression and crossed over to treatment with sunitinib malate as
well as 121 patients (32%) on the interferon alfa arm who received post-study
cancer treatment with sunitinib malate.
Cytokine-Refractory
The use of single-agent sunitinib malate in the treatment of cytokine-
refractory RCC was investigated in 2 single-arm, multi-center studies. All
patients enrolled into these studies experienced failure of prior cytokine-
based therapy. In Study 4 (NCT#00077974), failure of prior cytokine therapy
was based on radiographic evidence of disease progression defined by response
evaluation criteria in solid tumors (RECIST) or World Health Organization
(WHO) criteria during or within 9 months of completion of 1 cytokine therapy
treatment (interferon alfa, interleukin-2, or interferon alfa plus
interleukin-2; patients who were treated with interferon alfa alone must have
received treatment for at least 28 days). In Study 5 (NCT#00054886), failure
of prior cytokine therapy was defined as disease progression or unacceptable
treatment-related toxicity. The endpoint for both studies was ORR. Duration of
response (DR) was also evaluated.
One hundred and six patients (106) were enrolled into Study 4 and 63 patients
were enrolled into Study 5. Patients received 50 mg sunitinib malate on
Schedule 4/2. Therapy was continued until the patients met withdrawal criteria
or had progressive disease. The baseline age, sex, race, and ECOG performance
statuses of the patients were comparable between Studies 4 and 5.
Approximately 86%-94% of patients in the 2 studies were White. Men comprised
65% of the pooled population. The median age was 57 years and ranged from 24
to 87 years in the studies. All patients had an ECOG performance status <2 at
the screening visit.
The baseline malignancy and prior treatment history of the patients were
comparable between Studies 4 and 5. Across the 2 studies, 95% of the pooled
population of patients had at least some component of clear-cell histology.
All patients in Study 4 were required to have a histological clear-cell
component. Most patients enrolled in the studies (97% of the pooled
population) had undergone nephrectomy; prior nephrectomy was required for
patients enrolled in Study 4. All patients had received 1 previous cytokine
regimen. Metastatic disease present at the time of study entry included lung
metastases in 81% of patients. Liver metastases were more common in Study 4
(27% versus 16% in Study 5) and bone metastases were more common in Study 5
(51% versus 25% in Study 4); 52% of patients in the pooled population had at
least 3 metastatic sites. Patients with known brain metastases or
leptomeningeal disease were excluded from both studies.
The ORR and DR data from Studies 4 and 5 are provided in Table 12. There were
36 PRs in Study 4 as assessed by a core radiology laboratory for an ORR of
34.0% (95% CI: 25.0%, 43.8%). There were 23 PRs in Study 5 as assessed by the
investigators for an ORR of 36.5% (95% CI: 24.7%, 49.6%). The majority (>90%)
of objective disease responses were observed during the first 4 cycles; the
latest reported response was observed in Cycle 10. DR data from Study 4 is
premature as only 9 of 36 patients (25%) responding to treatment had
experienced disease progression or died at the time of the data cutoff.

Adjuvant Treatment
In the adjuvant treatment setting, sunitinib malate was investigated in S-TRAC
(NCT#00375674), a multi-center, international, randomized, double-blind,
placebo-controlled, trial in patients with high risk of recurrent RCC
following nephrectomy. Patients were required to have clear cell histology and
high risk of recurrence defined as ≥T3 and/or N+ tumors. Six hundred fifteen
(615) patients were randomized 1:1 to receive either 50 mg sunitinib malate
once daily on Schedule 4/2 or placebo. Patients were treated for 9 cycles
(approximately 1 year), or until disease recurrence, unacceptable toxicity, or
withdrawal of consent.
Demographics were generally comparable between the sunitinib malate and
placebo arms with regard to age (median age 58 years), sex (73% male), and
race (84% White, 12% Asian and 4% Other). At randomization, most patients had
an ECOG performance status of 0 (74% sunitinib malate and 72% placebo). The
remainder of the patients had an ECOG performance status of 1; 1 patient on
sunitinib malate had a performance status of 2.
The major efficacy outcome measure was disease-free survival (DFS) in patients
receiving sunitinib malate versus placebo as assessed by blinded independent
central review (BICR). Overall survival was an additional endpoint. There was
a statistically significant improvement in DFS in patients who were treated
with sunitinib malate compared to placebo (Table 13 and Figure 3).
Prespecified subgroup analyses are presented in Table 14. At the time of the
DFS analysis, overall survival data were not mature, with 141/615 (23%)
patient deaths.

14.3 Pancreatic Neuroendocrine Tumors
Study 6 (NCT#00428597) was a multi-center, international, randomized, double-
blind, placebo-controlled study of single-agent sunitinib malate conducted in
patients with unresectable pNET. Patients were required to have documented
RECIST-defined disease progression within the prior 12 months and were
randomized (1:1) to receive either 37.5 mg sunitinib malate (N=86) or placebo
(N=85) once daily without a scheduled off-treatment period. The primary
objective was to compare PFS in patients receiving sunitinib malate versus
patients receiving placebo. Other endpoints included OS, ORR, and safety. Use
of somatostatin analogs was allowed in the study.
Demographics were comparable between the sunitinib malate and placebo groups.
Additionally, 49% of sunitinib malate patients had nonfunctioning tumors vs
52% of placebo patients, and 92% patients in both arms had liver metastases. A
total of 66% of sunitinib malate patients received prior systemic therapy
compared with 72% of placebo patients and 35% of sunitinib malate patients had
received somatostatin analogs compared with 38% of placebo patients. Patients
were treated until disease progression or withdrawal from the study. Upon
disease progression or study closure, patients were offered access to
sunitinib malate in a separate extension study.
As recommended by the Independent Data Monitoring Committee, the study was
terminated prematurely prior to the prespecified interim analysis. This may
have led to an over estimate of the magnitude of PFS effect. A clinically
significant improvement for sunitinib malate over placebo in PFS was seen by
both investigator and independent assessment. A hazard ratio favoring
sunitinib malate was observed in all subgroups of baseline characteristics
evaluated. OS data were not mature at the time of the analysis. There were 9
deaths in the sunitinib malate arm and 21 deaths in the placebo arm. A
statistically significant difference in ORR favoring sunitinib malate over
placebo was observed. Efficacy results are summarized in Table 15 and the
Kaplan-Meier curve for PFS is in Figure 4.

OVERDOSAGE SECTION
10 OVERDOSAGE
Treatment of overdose with sunitinib malate should consist of general supportive measures. There is no specific antidote for overdosage with sunitinib malate. If indicated, elimination of unabsorbed drug should be achieved by emesis or gastric lavage. Cases of accidental overdose have been reported; these cases were associated with adverse reactions consistent with the known safety profile of sunitinib malate, or without adverse reactions. In nonclinical studies, mortality was observed following as few as 5 daily doses of 500 mg/kg (3,000 mg/m2) in rats. At this dose, signs of toxicity included impaired muscle coordination, head shakes, hypoactivity, ocular discharge, piloerection, and gastrointestinal distress. Mortality and similar signs of toxicity were observed at lower doses when administered for longer durations.
NONCLINICAL TOXICOLOGY SECTION
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
The carcinogenic potential of sunitinib has been evaluated in 2 species: rasH2 transgenic mice and Sprague-Dawley rats. There were similar positive findings in both species. In rasH2 transgenic mice, gastroduodenal carcinomas and/or gastric mucosal hyperplasia, as well as an increased incidence of background hemangiosarcomas were observed at sunitinib daily doses of ≥25 mg/kg/day in studies of 1 or 6 months duration. No proliferative changes were observed in rasH2 transgenic mice at 8 mg/kg/day. Similarly, in a 2-year rat carcinogenicity study, administration of sunitinib in 28-day cycles followed by 7-day dose-free periods resulted in findings of duodenal carcinoma at doses as low as 1 mg/kg/day [approximately 0.9 times the combined AUC (combined systemic exposure of sunitinib plus its active metabolite) in patients administered the RDD of 50 mg]. At the high dose of 3 mg/kg/day (approximately 8 times the combined AUC in patients administered the RDD of 50 mg), the incidence of duodenal tumors was increased and was accompanied by findings of gastric mucous cell hyperplasia and by an increased incidence of pheochromocytoma and hyperplasia of the adrenal gland.
Sunitinib did not cause genetic damage when tested in in vitro assays [bacterial mutation (Ames test), human lymphocyte chromosome aberration] and an in vivo rat bone marrow micronucleus test.
In a female fertility and early embryonic development study, female rats were administered oral sunitinib (0.5, 1.5, 5 mg/kg/day) for 21 days prior to mating and for 7 days after mating. Preimplantation loss was observed in females administered 5 mg/kg/day (approximately 5 times the combined AUC in patients administered the RDD of 50 mg). No adverse effects on fertility were observed at doses ≤1.5 mg/kg/day (approximately equal to the combined AUC in patients administered the RDD of 50 mg). In addition, effects on the female reproductive system were identified in a 3-month oral repeat-dose monkey study (2, 6, 12 mg/kg/day). Ovarian changes (decreased follicular development) were noted at 12 mg/kg/day (approximately 5 times the combined AUC in patients administered the RDD of 50 mg), while uterine changes (endometrial atrophy) were noted at ≥2 mg/kg/day (approximately 0.4 times the combined AUC in patients administered the RDD of 50 mg). With the addition of vaginal atrophy, the uterine and ovarian effects were reproduced at 6 mg/kg/day (approximately 0.8 times the combined AUC in patients administered the RDD of 50 mg) in a 9-month monkey study (0.3, 1.5, and 6 mg/kg/day administered daily for 28 days followed by a 14-day respite).
In a male fertility study, no reproductive effects were observed in male rats dosed with 1, 3, or 10 mg/kg/day oral sunitinib for 58 days prior to mating with untreated females. Fertility, copulation, conception indices, and sperm evaluation (morphology, concentration, and motility) were unaffected by sunitinib at doses ≤10 mg/kg/day (approximately ≥26 times the combined AUC in patients administered the RDD of 50 mg).
