A transfusion administered to a patient who had a hemoglobin level of 9 g per deciliter or less with symptoms or 7 g per deciliter or less with or without symptoms qualified the patient for the study (qualifying transfusion) and established the hemoglobin set point. Eighty-seven patients underwent randomization. No patients died during the study. Patients 18 years of age or older who had received at least four transfusions during the previous 12 months were eligible. According to Rother, the results from SHEPHERD show eculizumab to be effective and safe in a more typical PNH population, compared with that studied in the previous TRIUMPH study. "Soliris is a potentially important step forward in the search for the first ever treatment for PNH. – … 3rd ed.

Changes in the levels of lactate dehydrogenase, PNH type III erythrocytes, and hemoglobin from baseline through week 26 were analyzed with the use of the same mixed model. This press release and further information about Alexion Pharmaceuticals, Inc. can be found at: http://www.alxn.com/. Version 4. The number of headaches that occurred was similar in the two groups after the first 2 weeks of therapy. Two patients in the eculizumab group did not complete the trial, one because traveling to the study center was inconvenient and the other because of pregnancy; these patients were included in the analyses.

In a previous small, open-label study involving patients with AQP4-IgG–positive disease, eculizumab, a terminal complement i… In the TRIUMPH study, 43 patients on eculizumab were compared with 44 patients on placebo in a double-blind ran-domized controlled trial, with the outcomes being the stabili-zation of Hb and transfusion independence.11 Hb stabilization occurred in 49% in the eculizumab … Rosse WF. Holguin MH, Fredrick LR, Bernshaw NJ, Wilcox LA, Parker CJ. TRIUMPH was not designed to detect an effect of eculizumab on survival or on the incidence of thrombotic events, which is the strongest risk factor for death in patients with PNH. Wiedmer T, Hall SE, Ortel TL, Kane WH, Rosse WF, Sims PJ. Intravascular hemolysis and the quality of life were also assessed. I bars indicate the standard error. Hymes, P.

In January, 2006, Alexion announced that the first of those two PNH trials, the TRIUMPH study, achieved its co-primary endpoints with statistical significance. In the eculizumab group, the mean (±SE) lactate dehydrogenase level decreased from 2199.7±157.7 U per liter at baseline to 327.3±67.6 U per liter at 26 weeks, whereas in the placebo group the levels remained elevated, with values of 2258.0±154.8 U per liter at baseline and 2418.9±140.3 U per liter at 26 weeks (P<0.001). At each of 16 sites one patient underwent randomization, at each of 6 sites two patients underwent randomization, and at each of 12 sites 3 or more patients underwent randomization. Rollins SA, Sims PJ. Dr. Rollins reports having received royalties for inventions he made before becoming an employee of Alexion Pharmaceuticals. The data provide support for the central role of intravascular hemolysis in the pathogenesis of the disease and indicate that eculizumab is an effective treatment in patients with PNH. Drs. ); the Institute of Transfusion Medicine, University Hospital, Ulm, Germany (H.S. Stabilization of Hemoglobin Levels and the Number of Units of Packed Red Cells Transfused during Treatment. Cell 1993;73:703-711, 2. Further analysis of results from the three studies earlier (phase II pilot study, TRIUMPH and SHEPHERD trials) revealed that eculizumab treatment led to a ~ 13-fold reduction in the rate of thromboembolism … In the phase III, double‐blind, placebo‐controlled, TRIUMPH study, eculizumab reduced haemolysis, … Blood 2004;103:2827-2834, 20. In the TRIUMPH study, patients received either placebo or eculizumab at a dose of 600 mg intravenously for the first 4 weeks, 900 mg at week 5, and then 900 mg every 2 … The Complement Inhibitor Eculizumab in Paroxysmal Nocturnal Hemoglobinuria. CHESHIRE, Conn., September 20, 2006 - Soliris™ (eculizumab), a novel monoclonal antibody drug developed by Alexion Pharmaceuticals, Inc. (Nasdaq: ALXN), significantly reduced symptoms of paroxysmal nocturnal hemoglobinuria (PNH), a severe life-threatening hemolytic anemia, as compared with placebo, according to the results of a study, TRIUMPH, published today in The New England Journal of Medicine. The two primary end points were the stabilization of hemoglobin levels and the number of units of packed red cells transfused. Figure 4: Reduction in hemolysis during treatment with eculizumab. Currently, there is no therapy that effectively reduces intravascular hemolysis or improves the symptoms in patients with PNH. Ten patients in the placebo group discontinued infusions because of a perceived lack of efficacy but remained in the study for monitoring, as prespecified in the protocol, and were included in the analyses. Eculizumab: The Multicenter, Open Label, Research De-sign Study]) [10–12]. Treatment with eculizumab also significantly improved overall health and patient functioning as measured by the EORTC QLQ-C30 instrument including global health status (P<0.001) and all five aspects of patient functioning: role (P<0.001), social (P=0.003), cognitive (P=0.002), physical (P<0.001) and emotional (P=0.008). Anemia and the need for transfusions to sustain hemoglobin levels occur frequently, as does deterioration of the patient's quality of life. We tested the safety and efficacy of eculizumab, a humanized monoclonal antibody against terminal complement protein C5 that inhibits terminal complement activation, in patients with paroxysmal nocturnal hemoglobinuria (PNH). The data also show significant stabilization of hemoglobin over a six month period, with 49% of Soliris™ treated patients achieving stabilization as compared to 0% for patients receiving placebo (p<0.001). Before treatment with eculizumab, the hemoglobin levels were maintained by transfusion. Importantly, PNH patients are at increased risk of forming life-threatening blood clots, or thromboses, which are a significant cause of death. Patients who had a complement deficiency, an active bacterial infection, or a history of meningococcal disease and those who had undergone bone marrow transplantation were also excluded. All reported P values are two-sided and were not adjusted for multiple analyses. Eculizumab inhibits terminal complement-mediated PNH RBC destruction by targeting C5. We are indebted to Michael Bombara and Dr. Henk-Andre Kroon for trial oversight; to Dr. Jason Chan for the statistical analysis; to Drs. With respect to the EORTC QLQ-C30 instrument, the eculizumab group had significant improvements in scores on the scale for global health status, on all five scales for functioning, on two of three symptom scales, and on three of six single-item measures, as compared with the placebo group (P≤0.01 for each scale and measure) (Table 3). As announced today, we have submitted the Biologics License Application for Soliris to the Food and Drug Administration in the United States. The common open-label 102-week phase 3 extension study is an. The TRIUMPH study was a randomized placebo-controlled trial in which a similar dosing schedule as the Pilot study (see above) was compared to infusions of saline in a double-blind randomized controlled trial. 6 In a previous randomized, placebo-controlled, phase 3 study (TRIUMPH), eculizumab … Alexion Pharmaceuticals is a biotechnology company working to develop and deliver life-changing drug therapies for patients with serious and life-threatening medical conditions.
