About NEXAVAR® (sorafenib) Tablets
NEXAVAR is approved in the U.S. for the treatment of patients with unresectable hepatocellular carcinoma, patients with advanced renal cell carcinoma and patients with locally recurrent or metastatic, progressive, differentiated thyroid carcinoma refractory to radioactive iodine treatment. Nexavar is thought to inhibit both the tumor cell and tumor vasculature. In in vitro studies, Nexavar has been shown to inhibit multiple kinases thought to be involved in both cell proliferation (growth) and angiogenesis (blood supply) – two important processes that enable cancer growth. These kinases include Raf kinase, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 and RET.
Nexavar is currently approved in more than 100 countries. Nexavar is also being evaluated by Bayer and Onyx, international study groups, government agencies and individual investigators in a range of cancers.
Nexavar is co-developed by Onyx and Bayer, except in Japan where Bayer manages all development. The companies co-promote Nexavar in the U.S. Outside of the U.S. Bayer has exclusive marketing rights, and Bayer and Onyx share profits globally, excluding Japan.
Important Safety Considerations For Nexavar® (sorafenib) Tablets
Nexavar in combination with carboplatin and paclitaxel is contraindicated in patients with squamous cell lung cancer.
Cardiac ischemia and/or myocardial infarction may occur. The incidence of cardiac ischemia/infarction in Nexavar-treated vs. placebo-treated patients was 2.7% vs. 1.3%, 2.9% vs. 0.4%, and 1.9% vs. 0% in the HCC, RCC, and DTC studies, respectively. Temporary or permanent discontinuation of Nexavar should be considered in patients who develop cardiac ischemia and/or myocardial infarction.
An increased risk of bleeding may occur following Nexavar administration. The following bleeding adverse reactions were reported in the Nexavar-treated vs. placebo-treated patients, respectively, in the HCC study: bleeding from esophageal varices (2.4% vs. 4%) and bleeding with fatal outcome at any site (2.4% vs. 4%); in the RCC study: bleeding regardless of causality (15.3% vs. 8.2%), Grade 3 bleeding (2.0% vs. 1.3%), Grade 4 bleeding (0% vs. 0.2%), and one fatal hemorrhage in each treatment group; in the DTC study: bleeding (17.4% vs. 9.6%) and Grade 3 bleeding (1% vs. 1.4%). If bleeding necessitates medical intervention, consider permanent discontinuation of Nexavar.
Hypertension may occur early in the course of treatment. Monitor blood pressure weekly during the first 6 weeks and periodically thereafter, and treat, if required.
Hand-foot skin reaction and rash are common and management may include topical therapies for symptomatic relief. In cases of any severe or persistent adverse reactions, temporary treatment interruption, dose modification, or permanent discontinuation of Nexavar should be considered. Nexavar should be discontinued if Stevens-Johnson syndrome or toxic epidermal necrolysis are suspected as these may be life-threatening.
Gastrointestinal perforation was an uncommon adverse reaction and has been reported in less than 1% of patients taking Nexavar. Discontinue Nexavar in the event of a gastrointestinal perforation.
Patients taking concomitant warfarin should be monitored regularly for changes in prothrombin time (PT), International Normalized Ratio (INR), or clinical bleeding episodes.
Temporary interruption of Nexavar therapy is recommended in patients undergoing major surgical procedures.
Nexavar, in combination with gemcitabine/cisplatin, is not recommended in patients with squamous cell lung cancer. The safety and effectiveness of Nexavar has not been established in patients with non-small cell lung cancer.
Nexavar can prolong the QT/QTc interval and increase the risk for ventricular arrhythmias. Avoid use in patients with congenital long QT syndrome and monitor patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, and electrolyte abnormalities. Interrupt Nexavar if QTc interval is greater than 500 milliseconds or for an increase from baseline of 60 milliseconds or greater.
Drug-induced hepatitis with Nexavar may result in hepatic failure and death. Liver function tests should be monitored regularly and in cases of increased transaminases without alternative explanation Nexavar should be discontinued.
Nexavar may cause fetal harm when administered to a pregnant woman. Women of child-bearing potential should be advised to avoid becoming pregnant while on Nexavar and female patients should also be advised against breastfeeding while receiving Nexavar.
In DTC, Nexavar impairs exogenous thyroid suppression. Elevation of thyroid stimulating hormone (TSH) level above 0.5 mU/L was observed in 41% of Nexavar-treated patients as compared with 16% of placebo-treated patients in the DTC study. Monitor TSH levels monthly and adjust thyroid replacement medication as needed in patients with DTC.
Elevations in serum lipase and reductions in serum phosphate of unknown etiology have been associated with Nexavar.
Avoid concomitant use of strong CYP3A4 inducers, when possible, because inducers can decrease the systemic exposure of sorafenib. Nexavar exposure decreases when co-administered with oral neomycin. Effects of other antibiotics on Nexavar pharmacokinetics have not been studied.
Most common adverse reactions reported for Nexavar -treated patients vs. placebo-treated patients in unresectable HCC, respectively, were: diarrhea (55% vs. 25%), fatigue (46% vs. 45%), abdominal pain (31% vs. 26%), weight loss (30% vs. 10%), anorexia (29% vs. 18%), nausea (24% vs. 20%), and hand-foot skin reaction (21% vs. 3%). Grade 3/4 adverse reactions were 45% vs. 32%.
Most common adverse reactions reported for Nexavar -treated patients vs. placebo-treated patients in advanced RCC, respectively, were: diarrhea (43% vs. 13%), rash/desquamation (40% vs. 16%), fatigue (37% vs. 28%), hand-foot skin reaction (30% vs. 7%), alopecia (27% vs. 3%), and nausea (23% vs. 19%). Grade 3/4 adverse reactions were 38% vs. 28%.
Most common adverse reactions reported for Nexavar -treated patients vs. placebo-treated patients in DTC, respectively, were: Palmar-plantar erythrodysesthesia syndrome (PPES) (69% vs. 8%), diarrhea (68% vs. 15%), alopecia (67% vs. 8%), weight loss (49% vs. 14%), fatigue (41% vs. 20%), hypertension (41% vs. 12%), rash (35% vs. 7%), decreased appetite (30% vs. 5%), stomatitis (24% vs. 3%), nausea (21% vs. 12%), pruritus (20% vs. 11%), and abdominal pain (20% vs. 7%). Grade 3/4 adverse reactions were 65% vs. 30%.

About Xofigo® (radium Ra 223 dichloride) Injection
Xofigo is an alpha particle-emitting radioactive therapeutic agent with an anti-tumor effect on bone metastases. The active ingredient in Xofigo is the alpha particle-emitting isotope radium-223, which mimics calcium and forms complexes with the bone mineral hydroxyapatite at areas of increased bone turnover, such as bone metastases. The high linear energy transfer of Xofigo may cause double-strand DNA breaks in adjacent cells, resulting in an anti-tumor effect on bone metastases. The alpha particle range from radium Ra 223 dichloride is less than 100 micrometers which may limit the damage to the surrounding normal tissue.

About Stivarga (regorafenib)
In the United States, Stivarga is indicated for the treatment of patients with mCRC who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if KRAS wild type, an anti-EGFR therapy. It is also indicated for the treatment of patients with locally advanced, unresectable or metastatic GIST who have been previously treated with imatinib mesylate and sunitinib malate.
Stivarga is an inhibitor of multiple kinases involved in normal cellular functions and in pathologic processes such as oncogenesis, tumor angiogenesis and maintenance of the tumor microenvironment.
Stivarga is a compound developed by Bayer. In 2011, Bayer entered into an agreement with Onyx Pharmaceuticals, Inc., an Amgen subsidiary (NASDAQ: AMGN), under which Onyx receives a royalty on all global net sales of Stivarga in oncology.
Important Safety Information for Stivarga® (regorafenib) tablets:
Severe drug-induced liver injury with fatal outcome occurred in 0.3% of 1200 Stivarga-treated patients across all clinical trials. In metastatic colorectal cancer (mCRC), fatal hepatic failure occurred in 1.6% of patients in the Stivarga arm and in 0.4% of patients in the placebo arm; all the patients with hepatic failure had metastatic disease in the liver. In gastrointestinal stromal tumor (GIST), fatal hepatic failure occurred in 0.8% of patients in the Stivarga arm.
Obtain liver function tests (ALT, AST, and bilirubin) before initiation of Stivarga and monitor at least every 2 weeks during the first 2 months of treatment. Thereafter, monitor monthly or more frequently as clinically indicated. Monitor liver function tests weekly in patients experiencing elevated liver function tests until improvement to less than 3 times the upper limit of normal (ULN) or baseline values. Temporarily hold and then reduce or permanently discontinue Stivarga, depending on the severity and persistence of hepatotoxicity as manifested by elevated liver function tests or hepatocellular necrosis.
Stivarga caused an increased incidence of hemorrhage. The overall incidence (Grades 1-5) was 21% and 11% with Stivarga vs 8% and 3% with placebo in mCRC and GIST patients, respectively. Fatal hemorrhage occurred in 4 of 632 (0.6%) Stivarga -treated patients and involved the respiratory, gastrointestinal, or genitourinary tracts. Permanently discontinue Stivarga in patients with severe or life-threatening hemorrhage and monitor INR levels more frequently in patients receiving warfarin.
Stivarga caused an increased incidence of hand-foot skin reaction (HFSR) (also known as palmar-plantar erythrodysesthesia [PPE]) and severe rash, frequently requiring dose modification. The overall incidence was 45% and 67% with Stivarga vs 7% and 12% with placebo in mCRC and GIST patients, respectively. Incidence of Grade 3 HFSR (17% vs 0% in mCRC and 22% vs 0% in GIST), Grade 3 rash (6% vs <1% in mCRC and 7% vs 0% in GIST), serious adverse reactions of erythema multiforme (0.2% vs 0% in mCRC), and Stevens-Johnson syndrome (0.2% vs 0% in mCRC) was higher in Stivarga-treated patients. Toxic epidermal necrolysis occurred in 0.17% of 1200 Stivarga -treated patients across all clinical trials. Withhold Stivarga, reduce the dose, or permanently discontinue depending on the severity and persistence of dermatologic toxicity.
Stivarga caused an increased incidence of hypertension (30% vs 8% in mCRC and 59% vs 27% in GIST with Stivarga vs placebo, respectively). Hypertensive crisis occurred in 0.25% of 1200 Stivarga-treated patients across all clinical trials. Do not initiate Stivarga until blood pressure is adequately controlled. Monitor blood pressure weekly for the first 6 weeks of treatment and then every cycle, or more frequently, as clinically indicated. Temporarily or permanently withhold Stivarga for severe or uncontrolled hypertension.
Stivarga increased the incidence of myocardial ischemia and infarction in mCRC (1.2% with Stivarga vs 0.4% with placebo). Withhold Stivarga in patients who develop new or acute cardiac ischemia or infarction, and resume only after resolution of acute cardiac ischemic events if the potential benefits outweigh the risks of further cardiac ischemia.
Reversible Posterior Leukoencephalopathy Syndrome (RPLS) occurred in 1 of 1200 Stivarga-treated patients across all clinical trials. Perform an evaluation for RPLS in any patient presenting with seizures, headache, visual disturbances, confusion, or altered mental function. Confirm the diagnosis of RPLS with MRI and discontinue Stivarga in patients who develop RPLS.
Gastrointestinal perforation or fistula occurred in 0.6% of 1200 patients treated with Stivarga across clinical trials. In GIST, 2.1% (4/188) of Stivarga-treated patients developed gastrointestinal fistula or perforation: of these, 2 cases of gastrointestinal perforation were fatal. Permanently discontinue Stivarga in patients who develop gastrointestinal perforation or fistula.
Treatment with Stivarga should be stopped at least 2 weeks prior to scheduled surgery. Resuming treatment after surgery should be based on clinical judgment of adequate wound healing. Stivarga should be discontinued in patients with wound dehiscence.
Stivarga can cause fetal harm when administered to a pregnant woman. Use effective contraception during treatment and up to 2 months after completion of therapy. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.
Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Stivarga, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
The most frequently observed adverse drug reactions (greater than or equal to 30%) in Stivarga-treated patients vs placebo-treated patients in mCRC, respectively, were: asthenia/fatigue (64% vs 46%), decreased appetite and food intake (47% vs 28%), HFSR/PPE (45% vs 7%), diarrhea (43% vs 17%), mucositis (33% vs 5%), weight loss (32% vs 10%), infection (31% vs 17%), hypertension (30% vs 8%), and dysphonia (30% vs 6%).
The most frequently observed adverse drug reactions (greater than or equal to 30%) in Stivarga-treated patients vs placebo-treated patients in GIST, respectively, were: HFSR/PPE (67% vs 15%), hypertension (59% vs 27%), asthenia/fatigue (52% vs 39%), diarrhea (47% vs 9%), mucositis (40% vs 8%), dysphonia (39% vs 9%), infection (32% vs 5%), decreased appetite and food intake (31% vs 21%), and rash (30% vs 3%).
