The mean (standard deviation [SD]) total number of packed red blood cell units transfused during the treatment period was comparable in the ravulizumab (4.3 [4.76]) and eculizumab (3.4 [3.01]) treatment groups (Table 3). The red triangle indicates the noninferiority margin. This trial was funded by Alexion Pharmaceuticals, Inc., and is registered at www.clinicaltrials.gov as #NCT03056040. With ULTOMIRIS, you can experience the freedom of up to 8 weeks between infusions a, with the comfort of established safety.Whether you or a child you care for had a recent atypical-HUS diagnosis, or you’ve been part of the atypical-HUS … This study demonstrates that patients with PNH may be safely and effectively switched from eculizumab (900 mg administered every 2 weeks) to ravulizumab administered every 8 weeks while maintaining the high level of efficacy, safety, and quality of life previously achieved with eculizumab. Of 208 patients screened for eligibility, 197 met all entry criteria and were randomly assigned (1:1) to ravulizumab or eculizumab. Treatment with ravulizumab also achieved noninferiority compared with eculizumab for all 4 key secondary end points, with all point estimates for treatment difference favoring ravulizumab (Figure 1B; Table 2). n = 50 male patients in the ravulizumab group and n = 48 male patients in the eculizumab group. Ravulizumab provided immediate, complete, and sustained inhibition … PCHG, percentage change. and R.P.d.L. One breakthrough hemolysis event was of unknown etiology. Values are reported as n (%) of patients. The alternative complement pathway is characterized by the cleavage of the complement protein C5into C5a and C5b fragments. has received consultancies and honoraria from Alexion, Roche, and Novartis and research funding from Alexion and Roche. At day 183, LDH normalization was achieved by 64 of 97 patients (66.0%) treated with ravulizumab and 58 of 98 patients (59.2%) treated with eculizumab (Figure 2). Although LDH levels increased by 8.4% in the eculizumab group and decreased 0.82% in the ravulizumab group at day 183, the difference did not reach statistical significance for superiority (P = .058). 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. 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. A US cost-minimization model comparing ravulizumab versus eculizumab for the treatment of atypical hemolytic uremic syndrome. The percentage of patients with a ≥3-point improvement in FACIT-Fatigue score was similar between the ravulizumab and eculizumab groups (37.1% vs 33.7%). 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).

In 191 patients completing 183 days of treatment, ravulizumab was noninferior to eculizumab (Pinf < .0006 for all end points), including percentage change in LDH (difference, 9.21% [95% confidence interval (CI), −0.42 to 18.84], P = .058 for superiority), breakthrough hemolysis (difference, 5.1 [95% CI, −8.89 to 18.99]), change in FACIT-Fatigue score (difference, 1.47 [95% CI, −0.21 to 3.15]), transfusion avoidance (difference, 5.5 [95% CI, −4.27 to 15.68]), and stabilized hemoglobin (difference, 1.4 [95% CI, −10.41 to 13.31]). These results are qualitatively similar to those observed in patients naive to C5 inhibitor therapy,26  providing further evidence that ravulizumab provides complete inhibition of C5 to levels <0.5 μg/mL compared with eculizumab, which did not provide complete inhibition in all patients, and may mitigate the observed incidence and clinical sequelae of breakthrough hemolysis that has been observed with labeled-dose eculizumab.17-19. The most frequently reported adverse event was headache (26.8%, ravulizumab; 17.3%, eculizumab). Atypical and secondary haemolytic uremic syndromes have a distinct presentation and no common genetic risk factors. treatment.

Complement inhibition with eculizumab (Soliris) has become the gold standard for treating patients with atypical hemolytic uremic syndrome (aHUS) since its approval in 2011. Of these 5 patients with breakthrough hemolysis, 4 had 1 event each and 1 had 3 events, the third of which resulted in hospitalization and subsequent study discontinuation because of lack of efficacy (this patient subsequently received eculizumab 1200 mg every 2 weeks). All received meningococcal vaccination if they had not received it in the past 3 years. [2] Treatment difference was estimated for ravulizumab − eculizumab, except for breakthrough hemolysis, where treatment difference was based on eculizumab − ravulizumab. Normal range, 11.5 to 16.0 g/dL (women) and 13.0 to 17.5 g/dL (men). Kulasekararaj AG, Hill A, Rottinghaus ST, et al. 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. contributed to the study protocol, contributed to the manuscript, and approved the final version; and A.R. The long-acting C5 inhibitor, Ravulizumab, is effective and safe in adult patients with atypical hemolytic uremic syndrome naïve to complement inhibitor treatment. Department of Nephrology and Hypertension, Medical School Hannover, Hannover, Germany. No meningococcal infections or discontinuations due to adverse events occurred. The target of ravulizumab-cwvz is the same eculizumab (Soliris) with changes … Ravulizumab-cwvz (Ultomiris) is a second generation monoclonal antibody for aHUS made by Alexion pharmaceuticals, Inc. During this window we have temporarily removed the Registration feature. Once this occurs, the resulting eculizumab… It is a Complement inhibitor too. Genetic variants in C5 and poor response to eculizumab. History of major adverse vascular events was not a component of the randomization stratification criteria. Patients randomly assigned to the eculizumab treatment group received 900 mg every 2 weeks. Both ravulizumab and eculizumab dramatically improved the platelet count after 1 week. Therefore, and solely to indicate this fact, this article is hereby marked “advertisement” in accordance with 18 USC section 1734. Eculizumab-treated patients received a weight-based loading dose of ravulizumab followed 2 weeks later by weight-based maintenance doses every 8 weeks. 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]). Additionally, 2 events with complete C5 inhibition were associated with infection. 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.

C5a is a pro-in… 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. 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. 23 In ravulizumab… Similarly, mean LDH values were within the normal range at baseline and generally sustained over time (supplemental Appendix, section 3; supplemental Figure 3). 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. Atypical hemolytic uremic syndrome and C3 glomerulopathy: conclusions from a “Kidney Disease: Improving Global Outcomes” (KDIGO) Controversies Conference.

Percentage of patients achieving LDH normalization over time in the ravulizumab and eculizumab treatment groups. Is ravulizumab the new treatment of choice for atypical hemolytic uremic syndrome (aHUS)? An overview of adverse events is shown in Table 4. In this phase 3, open-label, multicenter study, 195 PNH patients on labeled-dose (900 mg every 2 weeks) eculizumab for >6 months were randomly assigned 1:1 to switch to ravulizumab (n = 97) or continue eculizumab (n = 98). In aHUS, mutations in complement pathway genes, such as CFH, MCP (CD46), and CFI, lead to the uncontrolled activation of the alternative complement pathway, leading to thrombotic microangiopathy (TMA)or blood clots in small blood vessels. 1 Last year, ravulizumab (Ultomiris), a long-acting C5 inhibitor derived from eculizumab, received FDA and EMEA approval for the treatment of patients with paroxysmal nocturnal hematuria (PNH). S.T.R., L.S., A.I.D., and S.O. Elsevier journal websites will be undergoing maintenance on Monday March 15 from 3:00 am to 5:00 pm US Eastern. If noninferiority was established for all key secondary end points, then superiority was assessed via a closed-testing procedure, using a 2-sided 0.05 test for each parameter, in the following order: percentage change in LDH, FACIT-Fatigue, breakthrough hemolysis, stabilized hemoglobin, and transfusion avoidance (supplemental Appendix, section 2). The FDA will review ravulizumab for the treatment of … Here we evaluate the efficacy and safety of ravulizumab in adults with atypical hemolytic uremic syndrome presenting with thrombotic microangiopathy. 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. Baseline (BL) is defined as the last nonmissing value before first dose of study drug. has received consultancies, honoraria, and research funding from Alexion, Novartis, and Pfizer and research funding from Amgen. Presented at 60th annual meeting of the American Society of Hematology, San Diego, CA, 1-4 December 2018. Mean (95% CI) free C5 levels in the ravulizumab and eculizumab groups over time. By continuing you agree to the, https://doi.org/10.1016/j.kint.2020.03.011. Most likely aHUS patients would say the same about their quality of life improvement from fewer infusions. Two patients withdrew before receiving study drug, and 195 received treatment (ravulizumab, n = 97; eculizumab, n = 98) (supplemental Appendix, section 3; supplemental Figure 2). R.P.d.L. The pharmacodynamic analysis was performed on all patients who received at least 1 dose of study drug and who had evaluable data. Although an increased risk of meningococcal infections has been reported in recipients of complement inhibitor therapy,13,14,28,29  no such infections were observed in the present trial. LDH normalization is defined as proportion of patients who achieved LDH level ≤1× the ULN (246 U/L). The authors thank Lori Volles, Rodrigo Pavani, and Masayo Ogawa of Alexion Pharmaceuticals for their contribution to the implementation of the study. [1] For the end points transfusion avoidance (TA), breakthrough hemolysis (BTH), and stabilized hemoglobin (HGB-S), Diff (95% CI) was based on estimated differences in percentage with 95% CI. Ravulizumab every 8 weeks is noninferior to eculizumab every 2 weeks across all efficacy end points in C5 inhibitor–naive PNH patients. Improved renal recovery in patients with atypical hemolytic uremic syndrome following rapid initiation of eculizumab treatment. Efficacy analyses were performed on the full analysis set (all patients who received at least 1 dose of ravulizumab or eculizumab). Testing of the noninferiority hypothesis is assessed by comparing the bolded limit of the 95% CI to the noninferiority margin. Eighty-five of 97 patients (87.6%) receiving ravulizumab and 81 of 98 patients (82.7%) receiving eculizumab avoided transfusion, with a between-group difference of 5.5% (95% CI, −4.27% to 15.68%, Pinf < .0001), whereas 74 of 97 patients (76.3%) receiving ravulizumab and 74 of 98 patients (75.5%) receiving eculizumab achieved stabilized hemoglobin levels (difference, 1.4% [95% CI, −10.41% to 13.31%], Pinf < .0005).

Based on 2 prospective studies in mostly adults andretrospective data in children, eculizumab, a terminal complement inhibitor, isapproved for aHUS treatment. Ravulizumab (ALXN1210) is a new complement component 5 (C5) inhibitor that produces immediate, complete, and sustained inhibition of C5 with an extended, 8-week dosing interval. 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). No adverse events led to withdrawal of study drug during the randomized treatment period. In this global, phase 3, single arm study in complement inhibitor-naïve adults (18 years and older) who fulfilled diagnostic criteria for atypical hemolytic uremic syndrome, enrolled patients received ravulizumab through a 26-week initial evaluation period. Clinical trial recommendations for potential Alport syndrome therapies. Key secondary efficacy end points were proportion of patients with breakthrough hemolysis, defined as at least 1 new or worsening symptom or sign of intravascular hemolysis (fatigue, hemoglobinuria, abdominal pain, shortness of breath [dyspnea], anemia [hemoglobin <10 g/dL], major adverse vascular event [including thrombosis], dysphagia, or erectile dysfunction) in the presence of elevated LDH ≥2× the ULN after prior reduction of LDH to <1.5× the ULN on treatment; change from baseline in quality of life, assessed with the FACIT-Fatigue Scale Version 4.0; transfusion avoidance, defined as the proportion of patients who remained transfusion free and did not require a transfusion per protocol-specified guidelines; and proportion of patients with stabilized hemoglobin, defined as avoidance of a ≥2-g/dL decrease in hemoglobin level from baseline in the absence of transfusion. Patient demographics and baseline clinical characteristics were well balanced between treatment groups (Table 1). Adverse events were recorded by type, incidence, and severity. Rates of complete thrombotic microangiopathy response were similar The body’s immune system uses the complement pathway to mark pathogens for targeted destruction by immune cells. By continuing you agree to the Use of Cookies. For all efficacy end points, ravulizumab achieved noninferiority compared with eculizumab. Drug maker Alexion, developer of the rare disease drug eculizumab (Soliris), announced Friday that the FDA has accepted for priority review its long-acting C5 complement inhibitor, ravulizumab (Ultomiris), which offers less frequent administration than eculizumab. The primary efficacy end point was hemolysis, as directly measured by percentage change in LDH levels from baseline to day 183. Of the 195 patients who received treatment, 191 completed the 26-week treatment period (ravulizumab, n = 96; eculizumab, n = 95). 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). Ravulizumab and eculizumab were well tolerated in this study. (A-B) A gyros-based fluorescence assay was used for patients who received ravulizumab (A), and an electrochemiluminescence immunoassay was used for patients who received eculizumab (B). Clinical and genetic predictors of atypical hemolytic uremic syndrome phenotype and outcome. 14 As previously described, eculizumab binds to the complement protein C5 in the intravascular space. (B) Secondary end point. Four of the 7 breakthrough hemolysis events were associated with time-matched free C5 ≥ 0.5 μg/mL, a level associated with incomplete inhibition of hemolysis.13,14  One of these was also associated with infection. Aims: Ravulizumab, engineered from eculizumab, provides sustained C5 inhibition in atypical hemolytic uremic syndrome (aHUS) … Additional secondary efficacy end points included total number of units of packed red blood cells transfused, proportion of patients with LDH in the normal range, change in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 scale (Version 3.0), change in clinical manifestations of PNH (fatigue, hemoglobinuria, abdominal pain, shortness of breath, chest pain, dysphagia, and erectile dysfunction), and proportion of patients experiencing major adverse vascular events.
