“We are disappointed by the outcome of this study as we had hoped the efficacy that INLYTA has demonstrated as a second-line treatment in patients with advanced renal cell carcinoma would carry over to patients with earlier stage disease, where it would delay or prevent disease relapse. That goal was not achieved. We will conduct additional analyses on the data that may provide insight into this result. Studies evaluating INLYTA in combination with immune checkpoint inhibitors for patients with a variety of advanced stage cancers, including RCC, will continue,” said Mace Rothenberg, M.D., Chief Development Officer, Oncology, Pfizer Global Product Development.
Detailed efficacy and safety data from ATLAS will be submitted for presentation at a future medical meeting.
INLYTA has had a significant impact on the treatment of patients with advanced RCC worldwide in its currently approved indications, supported by an extensive body of evidence in scientific literature including more than 50 publications. More than 66,000 patients have been treated with INLYTA to date.1 For more information on INLYTA, please visit www.INLYTA.com.
About RCC
Each year, approximately 338,000 new cases of kidney cancer are diagnosed worldwide, representing approximately 2-3 percent of all cancers.2,3,4 Renal cell carcinoma (RCC) is the most common type of kidney cancer, accounting for around 90 percent of cases.5 Approximately 75 percent of patients with clear cell RCC are non-metastatic, and 70-80 percent will have a nephrectomy with curative intent, or surgical removal of the tumor.6 However, a subset will relapse after surgery and once their disease becomes metastatic, their long-term prognosis is poor in advanced RCC with a 5-year survival rate as low as 12%.7
About ATLAS
ATLAS (A Randomized Double-Blind Phase 3 Study of Adjuvant Axitinib Versus Placebo in Subjects at High Risk of Recurrent RCC)(NCT01599754) is a global, multicenter, randomized double-blind Phase 3 trial that investigated the clinical efficacy and safety of adjuvant INLYTA (5 mg twice daily) versus placebo in patients (n=724) at high risk of recurrent RCC following nephrectomy. Patients were dosed up to 3 years (for a minimum of 1 year) in the study and the primary endpoint was disease-free survival (DFS). The study was conducted in collaboration with SFJ Pharmaceuticals, who provided the funding and clinical development supervision to generate the clinical data.
About INLYTA® (axitinib)
INLYTA 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). In the U.S., INLYTA is approved for the treatment of advanced renal cell carcinoma (RCC) after failure of one prior systemic therapy. INLYTA is also approved by the European Medicines Agency (EMA) for use in the EU in adult patients with advanced RCC after failure of prior treatment with sunitinib or a cytokine.
INLYTA Important 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.
Cardiac failure has been observed and can be fatal. Monitor for signs or symptoms of cardiac failure throughout treatment with INLYTA. Management of cardiac failure may require permanent discontinuation of INLYTA.
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.
No formal studies of the effect of INLYTA on wound healing have been conducted. 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 ALT, 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 (55% vs 53%), hypertension (40% vs 29%), fatigue (39% vs 32%), decreased appetite (34% vs 29%), nausea (32% vs 22%), dysphonia (31% vs 14%), hand-foot syndrome (27% vs 51%), weight decreased (25% vs 21%), vomiting (24% vs 17%), asthenia (21% vs 14%), and constipation (20% vs 20%).
The most common (≥10%) grade 3/4 AEs occurring in patients receiving INLYTA (vs sorafenib) were hypertension (16% vs 11%), diarrhea (11% vs 7%), and fatigue (11% vs 5%).
The most common (≥20%) lab abnormalities occurring in patients receiving INLYTA (all grades, vs sorafenib) included increased creatinine (55% vs 41%), decreased bicarbonate (44% vs 43%), hypocalcemia (39% vs 59%), decreased hemoglobin (35% vs 52%), decreased lymphocytes (absolute) (33% vs 36%), increased ALP (30% vs 34%), hyperglycemia (28% vs 23%), increased lipase (27% vs 46%), increased amylase (25% vs 33%), increased ALT (22% vs 22%), and increased AST (20% vs 25%).
