- Noninferiority to Epoetin in Maintenance of Hemoglobin (Hb) : The difference between the OMONTYS and epoetin-treated groups in the mean change in Hb levels from baseline to the study evaluation period (calculated as the mean of all measurements during weeks 29-36) in EMERALD 1 and 2 was -0.15 g/dL (95 percent CI: -0.30, -0.01) and 0.10 g/dL (95 percent CI: -0.05, 0.26) respectively.
- Similar Cardiovascular Safety in Hemodialysis Population : In the EMERALD studies, 22.8 percent of OMONTYS patients experienced one of the composite cardiovascular events, compared to 24.4 percent of epoetin patients (hazard ratio for the cardiovascular composite safety endpoint was 0.95 (0.77, 1.17) (95 percent CI)). OMONTYS is not indicated in patients with CKD not on dialysis. These patients experienced increased specific cardiovascular events.
"The EMERALD results are important because they not only evaluated the efficacy of OMONTYS and epoetin; they also represent data from the first studies to prospectively compare the cardiovascular safety of different erythropoiesis-stimulating agents (ESAs) for the treatment of anemia in dialysis patients with CKD,” said Steven Fishbane, M.D., Professor of Medicine, Hofstra North Shore-Long Island Jewish School of Medicine, lead author of the NEJM publication, and principal investigator for the EMERALD studies. “The EMERALD data demonstrated that OMONTYS administered once a month has a similar efficacy and cardiovascular safety profile when compared to epoetin administered one-to-three times weekly.”About the EMERALD Studies and Cardiovascular Safety Assessment Approximately 1,600 adult CKD hemodialysis patients across 178 sites in the U.S. and Europe were evaluated in the EMERALD 1 and 2 trials (1,066 patients received OMONTYS; 542 received epoetin). The primary efficacy endpoint of these studies was the mean change in Hb from the baseline Hb level to the mean level during the evaluation period (between weeks 29 through 36). In these trials, CKD patients on hemodialysis who were stable on epoetin, were randomized to receive OMONTYS either once every four weeks or to continue treatment with epoetin (according to epoetin labeling), with the dose adjusted as necessary to maintain Hb levels within the study-specified range (10.0-12.0 g/dL) for 52 weeks or more. Current Prescribing Information recommends reducing or interrupting the dose as Hb levels approach or exceed 11 g/dL. The EMERALD studies were part of the first Phase 3 program to prospectively evaluate the CV safety of different ESAs based on a composite cardiovascular safety endpoint (CSE). The CSE was adjudicated by a blinded and independent committee. Events included in the CSE pre-specified analysis were death from any cause, stroke, myocardial infarction, serious adverse events associated with congestive heart failure, unstable angina, or arrhythmia.
About Anemia Due to CKD in Adult Patients on DialysisAnemia is a complication of CKD and is associated with cardiovascular illness and mortality. As of 2010, the United States Renal Data System noted there were more than 410,000 people in the United States who were on dialysis. About OMONTYS ® (peginesatide) Injection OMONTYS is a synthetic, pegylated ESA. It is the only ESA that is peptide-based and its building blocks (amino acids) are arranged in a different order than erythropoietin (i.e., it has no sequence homology to endogenous erythropoietin). On March 27, 2012, the United States Food and Drug Administration approved OMONTYS for the treatment of anemia due to CKD in adult patients on dialysis. The product is the first ESA to be marketed in the United States (U.S.) in over 10 years and is the only once-monthly ESA for anemia available to this patient population in the United States. IMPORTANT SAFETY INFORMATION WARNING: ESAs INCREASE THE RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, THROMBOSIS OF VASCULAR ACCESS AND TUMOR PROGRESSION OR RECURRENCE. Chronic Kidney Disease:
- In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.
- No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks.
- Use the lowest OMONTYS dose sufficient to reduce the need for RBC transfusions.
- Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit. Use caution in patients with coexistent cardiovascular disease and stroke. Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality. A rate of hemoglobin rise of >1 g/dL over 2 weeks may contribute to these risks.
- In controlled clinical trials of ESAs in patients with cancer, increased risk for death and serious adverse cardiovascular reactions including myocardial infarction and stroke was observed.
- There is increased mortality and/or increased risk of tumor progression or recurrence in patients with cancer receiving ESAs.
- In controlled clinical trials of ESAs, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and deep venous thrombosis (DVT) in patients undergoing orthopedic procedures.
- In 2 trials of OMONTYS, patients with CKD not on dialysis experienced increased specific cardiovascular events.
