About Stivarga® (regorafenib) Tablets
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 gastrointestinal stromal tumor (GIST) who have been previously treated with imatinib mesylate and sunitinib malate.1

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.1

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:

WARNING: HEPATOTOXICITY

  • Severe and sometimes fatal hepatotoxicity has been observed in clinical trials.
  • Monitor hepatic function prior to and during treatment.
  • Interrupt and then reduce or discontinue Stivarga for hepatotoxicity as manifested by elevated liver function tests or hepatocellular necrosis, depending upon severity and persistence.

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%).

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.2

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 is contraindicated in patients with known severe hypersensitivity to sorafenib or any other component of NEXAVAR
  • 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%).There was no Grade 4 bleeding reported and there was one fatal hemorrhage in a placebo-treated patient. If bleeding necessitates medical intervention, consider permanent discontinuation of NEXAVAR. Due to the potential risk of bleeding, tracheal, bronchial, and esophageal infiltration should be treated with local therapy prior to administering NEXAVAR in patients with DTC
  • Monitor blood pressure weekly during the first 6 weeks and periodically thereafter, and treat, if required. In the HCC study, hypertension was reported in approximately 9.4% of NEXAVAR-treated patients and 4.3% of patients in the placebo-treated group. In the RCC study, hypertension was reported in approximately 16.9% of NEXAVAR-treated patients and 1.8% of patients in the placebo-treated group. In the DTC study, hypertension was reported in 40.6% of NEXAVAR-treated patients and 12.4% of the placebo-treated patients. Hypertension was usually mild to moderate, occurred early in the course of treatment, and was managed with standard antihypertensive therapy. In cases of severe or persistent hypertension despite institution of antihypertensive therapy, consider temporary or permanent discontinuation of NEXAVAR
  • Hand-foot skin reaction and rash are the most common adverse reactions attributed to NEXAVAR. 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. There have been reports of severe dermatologic toxicities, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). These cases may be life-threatening. Discontinue NEXAVAR if SJS or TEN are suspected
  • 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
  • Infrequent bleeding or elevations in the International Normalized Ratio (INR) have been reported in some patients taking warfarin while on NEXAVAR. Monitor patients taking concomitant warfarin regularly for changes in prothrombin time (PT), INR, or clinical bleeding episodes
  • Temporary interruption of NEXAVAR therapy is recommended in patients undergoing major surgical procedures
  • In a subset analysis of two randomized controlled trials in chemo-naive patients with Stage IIIB-IV non-small cell lung cancer, patients with squamous cell carcinoma experienced higher mortality with the addition of NEXAVAR compared to those treated with carboplatin/paclitaxel alone (HR 1.81, 95% CI 1.19–2.74) and gemcitabine/cisplatin alone (HR 1.22, 95% CI 0.82-1.80). 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 electrolytes and electrocardiograms in patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, including Class Ia and III antiarrhythmics, and electrolyte abnormalities. Correct electrolyte abnormalities (magnesium, potassium, calcium). Interrupt NEXAVAR if QTc interval is greater than 500 milliseconds or for an increase from baseline of 60 milliseconds or greater
  • Sorafenib-induced hepatitis is characterized by a hepatocellular pattern of liver damage with significant increases of transaminases which may result in hepatic failure and death. Increases in bilirubin and INR may also occur. 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
  • Female patients should 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. For patients with impaired TSH suppression while receiving NEXAVAR, the median maximal TSH was 1.6 mU/L and 25% had TSH levels greater than 4.4 mU/L. Monitor TSH levels monthly and adjust thyroid replacement medication as needed in patients with DTC
  • In the HCC study, the most common laboratory abnormalities observed in the NEXAVAR arm versus the placebo arm, respectively, were hypoalbuminemia (59% vs. 47%), lymphopenia (47% vs. 42%), thrombocytopenia (46% vs. 41%), elevation in INR (42% vs. 34%), elevated lipase (40% vs. 37%), hypophosphatemia (35% vs. 11%), elevated amylase (34% vs. 29%), hypocalcemia (27% vs. 15%), and hypokalemia (9.5% vs. 5.9%)
  • In the RCC study, the most common laboratory abnormalities observed in the NEXAVAR arm versus the placebo arm, respectively, were hypophosphatemia (45% vs. 11%), anemia (44% vs. 49%), elevated lipase (41% vs. 30%), elevated amylase (30% vs. 23%), lymphopenia (23% vs. 13%), neutropenia (18% vs. 10%), thrombocytopenia (12% vs. 5%), hypocalcemia (12% vs. 8%), and hypokalemia (5.4% vs. 0.7%)
  • In the DTC study, the most common laboratory abnormalities observed in the NEXAVAR arm versus the placebo arm, respectively, were elevated ALT (59% vs. 24%), elevated AST (54% vs. 15%), and hypocalcemia (36% vs. 11%).The relative increase for the following laboratory abnormalities observed in NEXAVAR-treated DTC patients as compared to placebo-treated patients is similar to that observed in the RCC and HCC studies: lipase, amylase, hypokalemia, hypophosphatemia, neutropenia, lymphopenia, anemia, and thrombocytopenia
  • 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 indicated for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases and no known visceral metastatic disease.

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.3

Important Safety Information for Xofigo® (radium Ra 223 dichloride) Injection

  • Contraindications: Xofigo is contraindicated in women who are or may become pregnant. Xofigo can cause fetal harm when administered to a pregnant woman.
  • Bone Marrow Suppression: In the randomized trial, 2% of patients in the Xofigo arm experienced bone marrow failure or ongoing pancytopenia, compared to no patients treated with placebo. There were two deaths due to bone marrow failure. For 7 of 13 patients treated with Xofigo bone marrow failure was ongoing at the time of death. Among the 13 patients who experienced bone marrow failure, 54% required blood transfusions. Four percent (4%) of patients in the Xofigo arm and 2% in the placebo arm permanently discontinued therapy due to bone marrow suppression. In the randomized trial, deaths related to vascular hemorrhage in association with myelosuppression were observed in 1% of Xofigo-treated patients compared to 0.3% of patients treated with placebo. The incidence of infection-related deaths (2%), serious infections (10%), and febrile neutropenia (<1%) was similar for patients treated with Xofigo and placebo. Myelosuppression – notably thrombocytopenia, neutropenia, pancytopenia, and leucopenia – has been reported in patients treated with Xofigo.
    Monitor patients with evidence of compromised bone marrow reserve closely and provide supportive care measures when clinically indicated. Discontinue Xofigo in patients who experience life-threatening complications despite supportive care for bone marrow failure.
  • Hematological Evaluation: Monitor blood counts at baseline and prior to every dose of Xofigo. Prior to first administering Xofigo, the absolute neutrophil count (ANC) should be greater than or equal to 1.5 × 109/L, the platelet count greater than or equal to 100 × 109/L, and hemoglobin greater than or equal to 10 g/dL. Prior to subsequent administrations, the ANC should be greater than or equal to 1 × 109/L and the platelet count greater than or equal to 50 × 109/L. Discontinue Xofigo if hematologic values do not recover within 6 to 8 weeks after the last administration despite receiving supportive care.
  • Concomitant Use with Chemotherapy: Safety and efficacy of concomitant chemotherapy with Xofigo have not been established. Outside of a clinical trial, concomitant use of Xofigo in patients on chemotherapy is not recommended due to the potential for additive myelosuppression. If chemotherapy, other systemic radioisotopes, or hemibody external radiotherapy are administered during the treatment period, Xofigo should be discontinued.
  • Administration and Radiation Protection: Xofigo should be received, used, and administered only by authorized persons in designated clinical settings. The administration of Xofigo is associated with potential risks to other persons from radiation or contamination from spills of bodily fluids such as urine, feces, or vomit. Therefore, radiation protection precautions must be taken in accordance with national and local regulations.
  • Fluid Status: Dehydration occurred in 3% of patients on Xofigo and 1% of patients on placebo. Xofigo increases adverse reactions such as diarrhea, nausea, and vomiting, which may result in dehydration. Monitor patients' oral intake and fluid status carefully and promptly treat patients who display signs or symptoms of dehydration or hypovolemia.
  • Injection Site Reactions: Erythema, pain, and edema at the injection site were reported in 1% of patients on Xofigo.
  • Secondary Malignant Neoplasms: Xofigo contributes to a patient's overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure may be associated with an increased risk of cancer and hereditary defects. Due to its mechanism of action and neoplastic changes, including osteosarcomas, in rats following administration of radium -223 dichloride, Xofigo may increase the risk of osteosarcoma or other secondary malignant neoplasms. However, the overall incidence of new malignancies in the randomized trial was lower on the Xofigo arm compared to placebo (<1% vs 2%; respectively), but the expected latency period for the development of secondary malignancies exceeds the duration of follow up for patients on the trial.
  • Subsequent Treatment with Cytotoxic Chemotherapy: In the randomized clinical trial, 16% patients in the Xofigo group and 18% patients in the placebo group received cytotoxic chemotherapy after completion of study treatments. Adequate safety monitoring and laboratory testing was not performed to assess how patients treated with Xofigo will tolerate subsequent cytotoxic chemotherapy.
  • Adverse Reactions: The most common adverse reactions (greater than or equal to 10%) in the Xofigo arm vs the placebo arm, respectively, were nausea (36% vs 35%), diarrhea (25% vs 15%), vomiting (19% vs 14%), and peripheral edema (13% vs 10%). Grade 3 and 4 adverse events were reported in 57% of Xofigo-treated patients and 63% of placebo-treated patients. The most common hematologic laboratory abnormalities in the Xofigo arm (greater than or equal to 10%) vs the placebo arm, respectively, were anemia (93% vs 88%), lymphocytopenia (72% vs 53%), leukopenia (35% vs 10%), thrombocytopenia (31% vs 22%), and neutropenia (18% vs 5%).
