The issue of drug price is also addressed, one hopes, with a more competitive market. Hillmen P, Lewis SM, Bessler M, Luzzatto L, Dacie JV. Paroxysmal nocturnal haemoglobinuria: long-term follow-up and prognostic factors. Socié G, Mary JY, de Gramont A, Rio B, Leporrier M, Rose C, et al. Pathophysiology, diagnosis, and treatment of paroxysmal nocturnal hemoglobinuria: a review. This long-term follow-up of patients with PNH demonstrated the sustained effectiveness of eculizumab and supports its well-established safety profile.Įculizumab Effectiveness Paroxysmal nocturnal hemoglobinuria Post-marketing surveillance Safety.ĭevalet B, Mullier F, Chatelain B, Dogné J-M, Chatelain C. The incidence of infection-related AEs was 20.57/100 patient-years, and included meningococcal infection in three patients (0.12/100 patient-years). Hemolysis was the most common AE (6.43/100 patient-years). The overall incidence of any AE was 69.92/100 patient-years. An estimated glomerular filtration rate ≥ 60 ml/min/1.73 m 2 and higher LDH level at baseline were associated with increases in Hb levels during eculizumab treatment. These changes were maintained for up to 5 years of treatment. Treatment with eculizumab significantly reduced lactate dehydrogenase (LDH) levels and significantly increased Hb levels. A total of 632 patients were enrolled and the median treatment duration was 3.6 years. The types and frequencies of adverse events (AEs) were assessed to determine its safety. The reduction in intravascular hemolysis, the change in hemoglobin (Hb) level, and the change in renal function were assessed to determine the effectiveness of eculizumab. FDA has approved a risk evaluation and mitigation strategy (REMS) for the treatment.All Japanese patients with paroxysmal nocturnal hemoglobinuria (PNH) treated with eculizumab were enrolled in post-marketing surveillance (PMS) between June 2010 and August 2019 to assess the long-term effectiveness and safety of eculizumab. The prescribing information for Empaveli contains a boxed warning that the drug may increase the risk of meningococcal and other serious infections caused by encapsulated bacteria that may become rapidly life threatening or fatal if not recognized and treated early. Notably, 85% of Empaveli-treated patients were didn't need transfusions over 16 weeks versus 15% of Soliris-treated patients In the head-to-head Phase 3 PEGASUS study, Empaveli met the primary endpoint, demonstrating superiority to Soliris for the change from baseline in hemoglobin level at Week 16 with an adjusted mean increase of 3.84 g/dL of hemoglobin.

PNH is a rare, chronic, life-threatening blood disorder caused by an acquired mutation, which leads to uncontrolled complement activation and the destruction of red blood cells through intravascular and extravascular hemolysis.Įmpaveli is approved for adults with PNH who are treatment naïve as well as patients switching from the C5 inhibitors eculizumab (Soliris, Alexion Pharmaceuticals) and ravulizumab (Ultomiris, Alexion). Related: Top 5 drugs in the pipeline that could have an impact this year PBM OptumRx had identified the medication as one of the top 5 drugs that will have an impact this year in its Drug Pipeline Insights Report, saying it could become the market leader in PNH treatments. FDA approved pegcetacoplan (Empaveli, Apellis), the first and only targeted C3 therapy for treatment of adults with paroxysmal nocturnal hemoglobinuria (PNH).
