Clinical
Sorafenib is used to treat advanced renal cell carcinoma (RCC; a type of cancer that begins in the kidneys). Sorafenib is also used to treat hepatocellular carcinoma (a type of liver cancer) that cannot be treated with surgery and a certain type of thyroid cancer that has spread to other parts of the body and cannot be treated with radioactive iodine. Sorafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.

5.1Cardiovascular Events In the SHARP (HCC) study, the incidence of cardiac ischemia/infarction was 2.7% in sorafenib-treated patients compared with 1.3% in those receiving placebo; in the TARGET (RCC) study, the incidence of cardiac ischemia/infarction was higher in the sorafenib-treated group (2.9%) compared with patients receiving placebo (0.4%), and in the DECISION (DTC) study, the incidence of cardiac ischemia/infarction was 1.9% in the sorafenib-treated group compared with 0% in patients receiving placebo. Patients with unstable coronary artery disease or recent myocardial infarction were excluded from this study.
In multiple clinical trials, congestive heart failure has been reported in 1.9% of sorafenib-treated patients (N=2276) [see Adverse Reactions ( 6.2 )] . Consider temporary or permanent discontinuation of sorafenib in patients who develop cardiovascular events [see Dosage and Administration ( 2.2 )] .
5.2Hemorrhage An increased risk of bleeding may occur following sorafenib administration. In the SHARP (HCC) study, the rates of bleeding from esophageal varices (2.4% and 4%) and of bleeding with a fatal outcome from any site (2.4% and 4%) were similar in sorafenib-treated patients and those receiving placebo, respectively. In the TARGET (RCC) study, bleeding was reported in 15.3% of patients in the sorafenib-treated group and 8.2% of patients receiving placebo.
The incidence of Grade 3 and 4 bleeding was 2% and 0%, respectively, in sorafenib-treated patients, and 1.3% and 0.2%, respectively, in those receiving placebo. There was one fatal hemorrhage in each treatment group in the TARGET (RCC) study. In the DECISION (DTC) study, bleeding was reported in 17.4% of sorafenib-treated patients and 9.6% of those receiving placebo; however, the incidence of Grade 3 bleeding was similar (1% and 1.4%) in sorafenib-treated patients and in those receiving placebo.
If any bleeding necessitates medical intervention, consider permanent discontinuation of sorafenib [see Dosage and Administration ( 2.2 )] . Due to the potential risk of bleeding, treat tracheal, bronchial, and esophageal infiltration with local therapy prior to administering sorafenib in patients with DTC.

Hemorrhage/bleeding was reported in 18% of those receiving sorafenib and 20% of patients receiving placebo.
The rates of Grade 3 and 4 bleeding were also higher in patients receiving placebo (Grade 3 - 3% sorafenib and 5% placebo and Grade 4 - 2% sorafenib and 4% placebo). Bleeding from esophageal varices was reported in 2.4% in sorafenib-treated patients and 4% of patients receiving placebo. Renal failure was reported in <1% of patients treated with sorafenib and 3% of patients receiving placebo.
Clinical pancreatitis was reported in 1 of 297 sorafenib-treated patients (Grade 2). The rate of adverse reactions (including those associated with progressive disease) resulting in permanent discontinuation was similar in both the sorafenib-treated patients and those receiving placebo (32%… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Strong CYP3A Inducers: Avoid strong CYP3A4 inducers. ( 7.1 )
7.1Effect of Other Drugs on Sorafenib Strong CYP3A4 Inducers The concomitant use of sorafenib with rifampin, a strong CYP3A4 inducer decreased the mean AUC of sorafenib, which may decrease the antitumor activity [see Clinical Pharmacology ( 12.3 )] . Avoid concomitant use of sorafenib with strong CYP3A4 inducers, when possible, because these drugs can decrease the systemic exposure to sorafenib. Neomycin The concomitant use of sorafenib with neomycin decreased the mean AUC of sorafenib, which may decrease the antitumor activity.
Avoid concomitant use of sorafenib with neomycin. The effects of other antibiotics on the pharmacokinetics of sorafenib have not been studied [see Clinical Pharmacology ( 12.3 )] .
7.2Concomitant Use of Warfarin The concomitant use of sorafenib and warfarin may increase the risk of bleeding or increased the INR. Monitor INR and for clinical bleeding episodes in patients taking warfarin while receiving sorafenib [see Warnings and Precautions ( 5.6 )] .
7.3Drugs That Prolong the QT Interval Sorafenib is associated with QTc interval prolongation. Avoid coadministration of sorafenib with medicinal products with a known potential to prolong QT/QTc interval [see Warnings and Precautions ( 5.9 ), Clinical Pharmacology ( 12.2 )] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation : Advise women not to breastfeed. ( 8.2 )
8.1Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , sorafenib may cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform a drug-associated risk. In animal reproduction studies, oral administration of sorafenib to pregnant rats and rabbits during the period of organogenesis resulted in embryo-fetal toxicities at maternal exposures that were significantly lower than human exposures at the recommended dose of 400 mg twice daily (see Data) .
Advise pregnant women and females of reproductive potential of the potential risk to a fetus. The background risk of major birth defects and 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% to 4% and 15% to 20%, respectively.
Data Animal Data In animal reproduction studies, sorafenib was teratogenic and induced embryo-fetal toxicity (including increased post-implantation loss, resorptions, skeletal retardations, and retarded fetal weight) when administered orally to pregnant rats and rabbits during the period of organogenesis. The effects occurred at doses considerably below the recommended human dose of 400 mg twice daily (approximately 500 mg/m 2 /day on a body surface area basis). Adverse intrauterine development effects were seen at doses >0.2 .mg/kg/day (1.2 mg/m 2 /day) in rats and ≥0.3 mg/kg/day (≥3.6 mg/m 2 /day) in rabbits.
These doses result in exposures (AUC) that are approximately 0.008 times the AUC in patients at the recommended dose.
8.2Lactation Risk Summary There are no data on the presence of sorafenib or its metabolites in human milk, or its effects on the breastfed child or on milk production. Sorafenib was present in milk of lactating rats (see Data) . Because of the potential for serious adverse reactions in a breastfed child from sorafenib, advise women not to breastfeed during treatment with sorafenib and for 2 weeks after the last dose.
Data Animal Data Following administration of radiolabeled sorafenib to lactating Wistar rats, approximately 27% of the radioactivity was secreted into milk. The milk to plasma AUC ratio was approximately 5:1.
8.3Females and Males of Reproductive Potential Sorafenib may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to the initiation of sorafenib. Contraception Females Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of sorafenib.
Males Based on genotoxicity and findings in animal reproduction studies, advise males with female partners of reproductive potential and pregnant partners to use effective contraception during treatment with sorafenib and for 3 months following the last dose of sorafenib [see Use in Specific Populations ( 8.1 ), Nonclinical Toxicology ( 13.1 )] . Infertility Males Based on findings in animal studies, sorafenib may impair fertility in males of reproductive potential [see Nonclinical Toxicology ( 13.1 )] .
8.4Pediatric Use The safety and effectiveness of sorafenib have not been established in pediatric patients. Juvenile Animal Toxicity Data Repeat dosing of sorafenib to young and growing dogs resulted in irregular thickening of the femoral growth plate at daily sorafenib doses ≥600 mg/m 2 (approximately 0.3 times the AUC at the recommended human dose), hypocellularity of the bone marrow adjoining the growth plate at 200 mg/m 2 /day (approximately 0.1 times the AUC at the recommended human dose), and alterations of the dentin composition at 600 mg/m 2 /day.
Similar effects were not observed in adult dogs when dosed for 4 weeks or le… [Excerpted — this section continues on DailyMed.]

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of sorafenib have not been established in pediatric patients. Juvenile Animal Toxicity Data Repeat dosing of sorafenib to young and growing dogs resulted in irregular thickening of the femoral growth plate at daily sorafenib doses ≥600 mg/m 2 (approximately 0.3 times the AUC at the recommended human dose), hypocellularity of the bone marrow adjoining the growth plate at 200 mg/m 2 /day (approximately 0.1 times the AUC at the recommended human dose), and alterations of the dentin composition at 600 mg/m 2 /day.
Similar effects were not observed in adult dogs when dosed for 4 weeks or less.
🧓 Geriatric Use ▾
8.5Geriatric Use In total, 59% of HCC patients treated with sorafenib were age 65 years or older and 19% were 75 and older. In total, 32% of RCC patients treated with sorafenib were age 65 years or older and 4% were 75 and older. No differences in safety or efficacy were observed between older and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
🆘 Overdosage ▾
10 OVERDOSAGE The adverse reactions observed at a dose of 800 mg twice daily (2 times the recommended dose) were primarily diarrhea and dermatologic. No information is available on symptoms of acute overdose in animals because of the saturation of absorption in oral acute toxicity studies conducted in animals. In cases of suspected overdose, withhold sorafenib and institute supportive care.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Sorafenib is a kinase inhibitor that decreases tumor cell proliferation in vitro . Sorafenib was shown to inhibit multiple intracellular (c-CRAF, BRAF and mutant BRAF) and cell surface kinases (KIT, FLT- 3, RET, RET/PTC, VEGFR-1, VEGFR- 2, VEGFR- 3, and PDGFR-ß). Several of these kinases are thought to be involved in tumor cell signaling, angiogenesis and apoptosis.
Sorafenib inhibited tumor growth of HCC, RCC, and DTC human tumor xenografts in immunocompromised mice. Reductions in tumor angiogenesis were seen in models of HCC and RCC upon sorafenib treatment, and increases in tumor apoptosis were observed in models of HCC, RCC, and DTC.
12.2Pharmacodynamics Cardiac Electrophysiology The effect of sorafenib 400 mg twice daily on the QTc interval was evaluated in a multi-center, open-label, non-randomized trial in 53 patients with advanced cancer. No large changes in the mean QTc intervals (that is, >20 ms) from baseline were detected in the trial. After one 28-day treatment cycle, the largest mean QTc interval change of 8.5 ms (upper bound of two-sided 90% confidence interval, 13.3 ms) was observed at 6 hours post-dose on day 1 of cycle 2 [see Warnings and Precautions ( 5.9 ), Drug Interactions ( 7.3 )] .
12.3Pharmacokinetics Multiple doses of sorafenib for 7 days resulted in a 2.5- to 7-fold accumulation compared to a single dose. Steady-state plasma sorafenib concentrations were achieved within 7 days, with a peak-to-trough ratio of mean concentrations of less than 2. The steady-state concentrations of sorafenib following administration of sorafenib 400 mg twice daily were evaluated in DTC, RCC and HCC patients.
Patients with DTC have mean steady-state concentrations that are 1.8-fold higher than patients with HCC and 2.3-fold higher than those with RCC. The reason for increased sorafenib concentrations in DTC patients is unknown. Mean C max and AUC increased less than proportionally beyond oral doses of 400 mg administered twice daily.
Absorption After administration of sorafenib tablets, the mean relative bioavailability was 38% to 49% when compared to an oral solution. Following oral administration, sorafenib reached peak plasma levels in approximately 3 hours. Effects of Food With a moderate-fat meal (30% fat; 700 calories), bioavailability was similar to that in the fasted state.
With a high-fat meal (50% fat; 900 calories), bioavailability was reduced by 29% compared to that in the fasted state. Distribution In vitro binding of sorafenib to human plasma proteins was 99.5%. Elimination The mean elimination half-life of sorafenib was approximately 25 to 48 hours.
Metabolism Sorafenib undergoes oxidative metabolism by hepatic CYP3A4, as well as glucuronidation by UGT1A9. Excretion Sorafenib accounted for approximately 70% to 85% of the circulating analytes in plasma at steady-state. Eight metabolites of sorafenib have been identified, of which 5 have been detected in plasma.
The main circulating metabolite of sorafenib, the pyridine N-oxide that comprises approximately 9% to 16% of circulating analytes at steady-state, showed in vitro potency similar to that of sorafenib. Following oral administration of a 100 mg dose of a solution formulation of sorafenib, 96% of the dose was recovered within 14 days, with 77% of the dose excreted in feces and 19% of the dose excreted in urine as glucuronidated metabolites. Unchanged sorafenib, accounting for 51% of the dose, was found in feces but not in urine.
Specific Populations A study of the pharmacokinetics of sorafenib indicated that the mean AUC of sorafenib in Asians (N=78) was 30% lower than in Whites (N=40). Sex and age do not have a clinically meaningful effect on the pharmacokinetics of sorafenib. Patients with Renal Impairment Mild (CLcr 50 to 80 mL/min), moderate (CLcr 30 to <50 mL/min), and severe (CLcr <30 mL/min) renal impairment do not affect the pharmacokinetics of sorafenib [see Use in Specific Populations ( 8.6 )]… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES
14.1Hepatocellular Carcinoma The SHARP (HCC) study (NCT00105443) was an international, multicenter, randomized, double blind, placebo-controlled trial in patients with unresectable hepatocellular carcinoma. Overall survival was the primary endpoint. A total of 602 patients were randomized; 299 to sorafenib 400 mg twice daily and 303 to matching placebo.
All 602 randomized subjects were included in the ITT population for the efficacy analyses. Demographics and baseline disease characteristics were similar between the sorafenib and placebo arms with regard to age, gender, race, performance status, etiology (including hepatitis B, hepatitis C and alcoholic liver disease), TNM stage (stage I: <1% vs. <1%; stage II: 10.4% vs. 8.3%; stage III: 37.8% vs.
43.6%; stage IV: 50.8% vs. 46.9%), absence of both macroscopic vascular invasion and extrahepatic tumor spread (30.1% vs. 30.0%), and Barcelona Clinic Liver Cancer stage (stage B: 18.1% vs.
16.8%; stage C: 81.6% vs. 83.2%; stage D: <1% vs. 0%).
Liver impairment by Child-Pugh score was comparable between the sorafenib and placebo arms (Class A: 95% vs. 98%; B: 5% vs. 2%).
Only one patient with Child-Pugh class C was entered. Prior treatments included surgical resection procedures (19.1% vs. 20.5%), locoregional therapies (including radiofrequency ablation, percutaneous ethanol injection and transarterial chemoembolization; 38.8% vs.
40.6%), radiotherapy (4.3% vs. 5.0%) and systemic therapy (3.0% vs. 5.0%).
The trial was stopped for efficacy following a pre-specified second interim analysis for survival showing a statistically significant advantage for sorafenib over placebo for overall survival (HR: 0.69, p= 0.00058) (see Table 10 and Figure 1). This advantage was consistent across all subsets analyzed. Final analysis of time to tumor progression (TTP) based on data from an earlier time point (by independent radiologic review) also was significantly longer in the sorafenib arm (HR: 0.58, p=0.000007) (see Table 10).

14.2Renal Cell Carcinoma The safety and efficacy of sorafenib in the treatment of advanced renal cell carcinoma (RCC) were studied in the following two randomized controlled clinical trials. TARGET TARGET (NCT00073307) was an international, multicenter, randomized, double blind, placebo-controlled trial in patients with advanced renal cell carcinoma who had received one prior systemic therapy. Primary study endpoints included overall survival and progression-free survival (PFS).
Tumor response rate was a secondary endpoint. The PFS analysis included 769 patients, per protocol, stratified by MSKCC (Memorial Sloan Kettering Cancer Center) prognostic risk category (low or intermediate) and country and randomized to sorafenib 400 mg twice daily (N=384) or to placebo (N=385). Table 11 summarizes the demographic and disease characteristics of the study population analyzed.
Baseline demographics and disease characteristics were well balanced for both treatment groups. The median time from initial diagnosis of RCC to randomization was 1.6 and 1.9 years for the sorafenib and placebo arms, r… [Excerpted — this section continues on DailyMed.]
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity studies have not been performed with sorafenib. Sorafenib was clastogenic when tested in an in vitro mammalian cell assay (Chinese hamster ovary) in the presence of metabolic activation. Sorafenib was not mutagenic in the in vitro Ames bacterial cell assay or clastogenic in an in vivo mouse micronucleus assay.
One intermediate in the manufacturing process, which is also present in the final drug substance (<0.15%), was positive for mutagenesis in an in vitro bacterial cell assay (Ames test) when tested independently. No specific studies with sorafenib have been conducted in animals to evaluate the effect on fertility. However, results from the repeat-dose toxicity studies suggest there is a potential for sorafenib to impair reproductive function and fertility.
Multiple adverse effects were observed in male and female reproductive organs, with the rat being more susceptible than mice or dogs. Typical changes in rats consisted of testicular atrophy or degeneration, degeneration of epididymis, prostate, and seminal vesicles, central necrosis of the corpora lutea and arrested follicular development. Sorafenib-related effects on the reproductive organs of rats were manifested at daily oral doses ≥5 mg/kg (30 mg/m 2 ).
This dose results in an exposure (AUC) that is approximately 0.5 times the AUC in patients at the recommended human dose. Dogs showed tubular degeneration in the testes at 30 mg/kg/day (600 mg/m 2 /day). This dose results in an exposure that is approximately 0.3 times the AUC at the recommended human dose.
Oligospermia was observed in dogs at 60 mg/kg/day (1200 mg/m 2 /day) of sorafenib.
