“We set a high bar in our INLYTA trials to understand how it compares to another VEGF-targeted therapy,” said Dr. Rothenberg. “Since approval, INLYTA has established its utility in the second-line setting where it is an important treatment option for many patients with advanced kidney cancer.”Pfizer is also investigating axitinib in the AGILE 1046 study, a randomized Phase 2 clinical trial in treatment-naïve patients with advanced RCC. Blinded efficacy data from this ongoing study were presented at ASCO earlier this year. Axitinib is also being studied in a randomized Phase 2 clinical trial for the treatment of hepatocellular carcinoma (HCC), which is currently closed to enrollment. Additionally, under a collaborative development agreement between Pfizer and SFJ Pharma Ltd. II, SFJ is conducting a Phase 3 clinical trial in Asia studying axitinib for adjuvant treatment of patients at high risk of recurrent RCC following nephrectomy (kidney removal).

Patients with questions should contact their treating physician. About INLYTA® (axitinib) INLYTA is indicated for the treatment of advanced RCC after failure of one prior systemic therapy. INLYTA, a kinase inhibitor, is an oral therapy that is designed to inhibit tyrosine kinases, including vascular endothelial growth factor (VEGF) receptors 1, 2 and 3; these receptors can influence tumor growth, vascular angiogenesis and progression of cancer (the spread of tumors). Important INLYTA® (axitinib) Safety Information Hypertension including hypertensive crisis has been observed. Blood pressure should be well controlled prior to initiating INLYTA. Monitor for hypertension and treat as needed. For persistent hypertension, despite use of antihypertensive medications, reduce the dose. Discontinue INLYTA if hypertension is severe and persistent despite use of antihypertensive therapy and dose reduction of INLYTA, and discontinuation should be considered if there is evidence of hypertensive crisis.
Arterial and venous thrombotic events have been observed and can be fatal. Use with caution in patients who are at increased risk or who have a history of these events.Hemorrhagic events, including fatal events, have been reported. INLYTA has not been studied in patients with evidence of untreated brain metastasis or recent active gastrointestinal bleeding and should not be used in those patients. If any bleeding requires medical intervention, temporarily interrupt the INLYTA dose. Gastrointestinal perforation and fistula, including death, have occurred. Use with caution in patients at risk for gastrointestinal perforation or fistula. Monitor for symptoms of gastrointestinal perforation or fistula periodically throughout treatment. Hypothyroidism requiring thyroid hormone replacement has been reported. Monitor thyroid function before initiation of, and periodically throughout, treatment. Stop INLYTA at least 24 hours prior to scheduled surgery. Reversible Posterior Leukoencephalopathy Syndrome (RPLS) has been observed. If signs or symptoms occur, permanently discontinue treatment. Monitor for proteinuria before initiation of, and periodically throughout, treatment. For moderate-to-severe proteinuria, reduce the dose or temporarily interrupt treatment. Liver enzyme elevation has been observed during treatment with INLYTA. Monitor alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin before initiation of, and periodically throughout, treatment. For patients with moderate hepatic impairment, the starting dose should be decreased. INLYTA has not been studied in patients with severe hepatic impairment. Women of childbearing potential should be advised of potential hazard to the fetus and to avoid becoming pregnant while receiving INLYTA. Avoid strong CYP3A4/5 inhibitors. If unavoidable, reduce the dose. Grapefruit or grapefruit juice may also increase INLYTA plasma concentrations and should be avoided. Avoid strong CYP3A4/5 inducers and, if possible, avoid moderate CYP3A4/5 inducers. The most common (≥20%) adverse events (AEs) occurring in patients receiving INLYTA (all grades, vs sorafenib) were diarrhea, hypertension, fatigue, decreased appetite, nausea, dysphonia, hand-foot syndrome, weight decreased, vomiting, asthenia, and constipation.
The most common (≥10%) grade 3/4 AEs occurring in patients receiving INLYTA (vs sorafenib) were hypertension, diarrhea, and fatigue.The most common (≥20%) lab abnormalities occurring in patients receiving INLYTA (all grades, vs sorafenib) included increased creatinine, decreased bicarbonate, hypocalcemia, decreased hemoglobin, decreased lymphocytes (absolute), increased ALP, hyperglycemia, increased lipase, increased amylase, increased ALT and increased AST.
