All participants gave written informed consent prior to study participation. The target of ravulizumab-cwvz is the same eculizumab (Soliris) with changes … n = 50 male patients in the ravulizumab group and n = 48 male patients in the eculizumab group. A difference in percentage change in LDH from baseline to day 183 between ravulizumab and eculizumab treatment groups along with a 2-sided 95% confidence interval (CI) were calculated. To read this article in full you will need to make a payment. Adverse events were recorded by type, incidence, and severity. At the end of the 26-week treatment period, ravulizumab-treated patients continued weight-based maintenance dosing of ravulizumab, whereas eculizumab-treated patients were switched to open-label ravulizumab for the extension period. (%), Time from PNH diagnosis to consent, mean (SD), y, History of major adverse vascular events, no. Post hoc P values were calculated for testing of noninferiority (Pinf) relative to the prespecified noninferiority margins to assess the strength of evidence of the study results. Baseline European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 subscale scores reflected a patient population with stable disease, and changes in scores during the study were similar in both treatment groups (supplemental Appendix, section 4; supplemental Table 1). Ultomiris (ravulizumab-cwvz) and Soliris (eculizumab) are monoclonal antibodies used to treat patients with paroxysmal nocturnal hemoglobinuria (PNH). Similarly, shifts in clinical manifestations of PNH were infrequent in both treatment groups, and no patient experienced a major adverse vascular event (Table 3). This 26-week, active-controlled study of 195 patients with PNH who were clinically stable on labeled-dose eculizumab treatment for a mean for 5.8 years demonstrated that ravulizumab administered every 8 weeks effectively inhibited complement-mediated hemolysis and had a safety profile similar to that of eculizumab.5-7 Ravulizumab met the primary end point (percentage change in LDH from baseline to day 183) and all key secondary end points, showing noninferiority to biweekly treatment with 900 mg eculizumab, the current standard of care for PNH.13,14 Point estimates consistently favored ravulizumab treatment over eculizumab treatment for the primary end point and all 4 key secondary efficacy end points, although none of the results from this noninferiority trial demonstrated superiority. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. The life time horizon used in the costs of treatments is not stated, but the relative life time costs are reported at around $9.4m for Eculizumab and $7.8m for Ravulizumab. Ravulizumab provided immediate, complete, and sustained inhibition … Eligible patients must have received eculizumab treatment of ≥6 months at labeled dose before study entry, had an LDH level ≤1.5× the upper limit of normal (ULN; 246 U/L) at screening, and been vaccinated against Neisseria meningitidis <3 years before dosing or at the time of study drug initiation to reduce the risk of meningococcal infections. Breakthrough hemolysis occurring as a result of complement-amplifying conditions such as infection may occur irrespective of free C5 and remains a possibility with the use of eculizumab and ravulizumab. Further details regarding data availability, instructions for requesting information, and our data disclosure policy are available at the Alexion Web site (http://alexion.com/research-development). An overview of adverse events is shown in Table 4. Results of phase 1b/2 studies in complement-inhibitor–naive patients with PNH demonstrate that ravulizumab provides rapid and sustained reduction in complement-mediated hemolysis at dosing intervals up to 12 weeks and overall improvement of PNH-related symptomatology and quality of life.25 In the largest phase 3 study in complement-inhibitor–naive PNH patients conducted to date, ravulizumab was shown to be noninferior to eculizumab for all end points, including transfusion avoidance, lactate dehydrogenase (LDH) normalization, percentage change in LDH levels, change in Functional Assessment of Chronic Illness Therapy (FACIT)–Fatigue score, breakthrough hemolysis, and hemoglobin stabilization.26 In this phase 3 study, we assessed the noninferiority of ravulizumab vs eculizumab in patients with PNH on stable eculizumab therapy. [1] Difference (Diff) (95% CI) was based on estimated difference in percentage with 95% CI. Treatment effect. Mean serum free C5 concentrations were suppressed to <0.5 µg/mL by the end of the first infusion and at all subsequent visits for all patients receiving ravulizumab; however, this threshold was not consistently met in the eculizumab group (Figure 3). Treat atypical-HUS with up to 8 weeks of freedom a. Here we evaluate the efficacy and safety of ravulizumab in adults with atypical hemolytic uremic … Baseline was defined as the last nonmissing value before the first dose of study drug. All analyses were performed using SAS release (SAS Institute Inc., Cary, NC), version 9.4 or higher, or other validated statistical software. This material is provided for educational purposes only … Horizontal line indicates free C5 level of 0.5 µg/mL. The FDA will review ravulizumab for the treatment of … By continuing you agree to the Use of Cookies. Key exclusion criteria included LDH value >2× the ULN in the 6 months before day 1, major adverse vascular event (supplemental Appendix, section 2) within 6 months before day 1, platelet count 30 × 109/L, absolute neutrophil count <0.5 × 109/L, body weight <40 kg at screening, history of bone marrow transplantation, and history of N meningitidis infection (supplemental Appendix, section 2). © 2020 International Society of Nephrology. Four patients discontinued the study, 1 in the ravulizumab group (withdrawal by subject) and 3 in the eculizumab group (withdrawal by subject, lack of efficacy [3 breakthrough hemolysis events], and pregnancy). Free C5 levels <0.5 µg/mL are associated with complete inhibition of C5 activity. The pharmacodynamic analysis was performed on all patients who received at least 1 dose of study drug and who had evaluable data. Published by Elsevier Inc. All rights reserved. Testing of the noninferiority hypothesis is assessed by comparing the bolded limit of the 95% CI to the noninferiority margin. If at any point noninferiority or superiority was not reached, then all subsequent tests were stopped. There were no treatment-emergent antidrug antibodies in patients treated with ravulizumab. The body’s immune system uses the complement pathway to mark pathogens for targeted destruction by immune cells. Among 7 episodes of breakthrough hemolysis, 4 were associated with inadequate C5 inhibition, 2 were primarily associated with infection, and 1 was of unclear etiology. Ravulizumab (ALXN1210) vs eculizumab … We use cookies to help provide and enhance our service and tailor content and ads. b Targeted engineering to incorporate 4 amino acid substitutions designed to reduce target-mediated drug disposition and enhance FcRn-mediated recycling into eculizumab … are employees and stockholders of Alexion Pharmaceuticals, Inc. J.W.L. This study was supported by Alexion Pharmaceuticals, Inc. For the primary end point of percentage change in LDH and the secondary end point of breakthrough hemolysis, estimates of the treatment difference were based upon (eculizumab − ravulizumab), while the remainder of the end points were based upon (ravulizumab − eculizumab). Here we prospectively evaluated efficacy and safety of weight-based dosing of eculizumab in eligible pediatric patients with aHUS … C5a is a pro-in… For stable patients receiving label-dose eculizumab therapy, providing an effective treatment duration that is 4 times longer between infusions by switching to ravulizumab given every 8 weeks is likely to result in a substantially reduced burden of treatment, fewer occurrences of breakthrough hemolysis and their clinical consequences, better quality of life, and greater likelihood of retention on long-term therapy. Patients were stratified according to transfusion history and were randomly assigned (1:1) to 26 weeks of open-label treatment with IV ravulizumab or eculizumab. Presented at 60th annual meeting of the American Society of Hematology, San Diego, CA, 1-4 December 2018. The online version of this article contains a data supplement. Patients with PNH may be safely and effectively switched from labeled-dose eculizumab administered every 2 weeks to ravulizumab administered every 8 weeks. Statistical analysis, pharmacokinetic and pharmacodyamic assessments, and editorial review were provided by Rasha Aguzzi, Rajendra Pradhan, and Stephan Ortiz of Alexion Pharmaceuticals. No adverse events led to withdrawal of study drug during the randomized treatment period. One breakthrough hemolysis event was of unknown etiology. The complete and sustained C5 inhibition associated with ravulizumab may account for the consistent results across end points. The safety profile of ravulizumab was consistent with that of eculizumab in the clinical trial program in PNH.5,7,27 Overall, the types and incidences of adverse events were comparable to those of other ravulizumab25,26 and eculizumab trials,5,7,27 with headache being the most commonly reported adverse event. Serious infections occurred in 2 patients (2.1%) in the ravulizumab group (influenza and lower respiratory tract infection [without positive culture]) and in 1 eculizumab-treated patient (1.0%) (acute pyelonephritis [causative agent unknown]). No meningococcal infections or discontinuations due to adverse events occurred. The lower bound of the 95% CI for the difference was −0.42%, which exceeded the protocol-specified noninferiority margin of −15%, indicating that ravulizumab is noninferior to eculizumab with a Pinf < .0006. This is ravulizumab … 14 As previously described, eculizumab binds to the complement protein C5 in the intravascular space. Ravulizumab’s brand name is “Ultomiris” , as “Soliris” is for eculizumab. Twelve patients experienced serious adverse events (4 ravulizumab patients and 8 eculizumab patients). Ravulizumab every 8 weeks is noninferior to eculizumab every 2 weeks across all efficacy end points in eculizumab-experienced PNH patients. Of 208 patients screened for eligibility, 197 met all entry criteria and were randomly assigned (1:1) to ravulizumab or eculizumab. There were no deaths and no cases of meningococcal infection. ALXN1210-PNH-302 was a multicenter, randomized, open-label, active-controlled study conducted in 49 centers in 11 countries (registered at www.clinicaltrials.gov as #NCT03056040 and EudraCT as #2016-002026-36, CHAMPION 302). Ravulizumab-cwvz (Ultomiris, Alexion) received FDA approval for the treatment of atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy (TMA) for adult and pediatric patients. A complete list of study investigators can be found in the supplemental Appendix, section 1. The study, “ A US cost-minimization model comparing ravulizumab versus eculizumab for the treatment of atypical hemolytic uremic … The authors also thank the investigators of ALXN1210-PNH-302, who are listed in the supplemental Appendix, section 1. Demographic and baseline clinical characteristics, Erythrocytes with complete deficiency in glycosylphosphatidylinositol-anchored proteins, including complement regulatory proteins CD59 and CD55.30. The key secondary end points were tested for noninferiority in a hierarchical manner provided that noninferiority was declared for the primary end point. Day 29, 43, 57, 85, 99, 113, 141, 155, and 169 data are from anytime for the ravulizumab group and predose for the eculizumab group. The discovery that uncontrolled complement system activation plays a key role in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH),1 atypical hemolytic uremic syndrome,2 and myasthenia gravis3,4 was established upon results of several trials demonstrating the efficacy and safety of complement-inhibitor therapy to treat these serious and potentially life-threatening diseases.5-12 Eculizumab (Soliris; Alexion Pharmaceuticals, Inc., Boston, MA), the only approved complement inhibitor for PNH,13,14 is associated with sustained improvements in intravascular hemolysis, anemia, thrombotic events, transfusion independence, survival, and quality of life.5-7,15,16 Although eculizumab therapy is highly effective, up to 27% of eculizumab-treated patients may experience breakthrough hemolysis,17-19 resulting in a return of PNH symptoms and increased risk of serious complications.
