Current and Emerging Therapies for C3 Glomerulopathy and Primary (Idiopathic) Immune Complex Membranoproliferative Glomerulonephritis.
(PubMed, Kidney Int Rep)
- "However, recent advances in targeted complement inhibitor therapy have been made in these diseases with positive results from phase 3 clinical trials of both the factor B inhibitor, iptacopan (in adults with native kidney C3G) and the C3/C3b inhibitor, pegcetacoplan (in adults and adolescents with native or posttransplant C3G or primary IC-MPGN). In this review, we summarize what is known and what questions still remain regarding the effect of complement inhibitors on widely accepted surrogate end points for efficacy in C3G/primary IC-MPGN (proteinuria, estimated glomerular filtration rate [eGFR], and kidney biopsy histology). Additional controversies, including candidate patient populations, optimal treatment duration, and how best to monitor patients on complement inhibitor therapy are also discussed, in an effort to prepare the nephrology community for innovative therapeutic options for patients whose long-term prognosis has generally been dismal."

Advancing treatment goals for paroxysmal nocturnal hemoglobinuria to align with quality of life improvements in the era of anti-complement therapy
(PubMed, Rinsho Ketsueki)
- "Eculizumab, a C5 inhibitor introduced in 2010, directly inhibits intravascular hemolysis, and thus not only resolves hemolysis-related symptoms but also prevents organ damage and improves survival...Various drugs have been developed to address these issues, including long-acting C5 inhibitors (ravulizumab and crovalimab) and proximal complement inhibitors capable of blocking extravascular hemolysis, such as a C3 inhibitor (pegcetacoplan), a factor B inhibitor (iptacopan), and a factor D inhibitor (danicopan). In particular, proximal complement inhibitors further enhance QOL because they inhibit both intravascular and extravascular hemolysis, resulting in greater improvement of hemoglobin levels and transfusion independence, and thereby further enhancing of QOL. Today, it is possible to achieve optimal improvement in QOL by appropriately selecting one of the three C5 inhibitors as first-line therapy or one of the three proximal complement inhibitors as second-line..."

Recurrence of C3 Glomerulopathy and Immune Complex-Mediated Membranoproliferative Glomerulonephritis After Kidney Transplantation: Challenges and Opportunities.
(PubMed, Kidney Int Rep)
- "Conventional treatments, including intensified immunosuppression, rituximab, and plasma exchange, have shown limited and inconsistent efficacy...Although eculizumab remains the most extensively studied agent, emerging proximal complement inhibitors such as iptacopan and pegcetacoplan have shown encouraging efficacy in both native and recurrent disease. However, optimal timing, prophylactic use, and long-term safety in transplant recipients remain uncertain. In this review, we outline the clinical spectrum, key diagnostic and therapeutic challenges, and emerging treatment strategies for recurrent C3G and IC-MPGN, highlighting advances that may ultimately improve graft survival and patient outcomes."

(2025), which reported BT-IVH in 14.8% of C5i-naive (event rate: 1.0 per 10 PY) and 7.8% of eculizumab-experienced patients (event rate: 0.33 per 10 PY) with PNH over a follow-up period of up to 6 years (median: 3.9 and 2.7 years, respectively). Overall, this analysis supports the use of ravulizumab, with only 6–7 infusions per year, as an effective treatment for patients with PNH in the real-world setting."

Optimizing PNH treatment with the complement inhibitor pegcetacoplan: A case report
(ASH 2025)
- "The current treatment landscape includes 6 approved complement cascade inhibitors: 3 C5 inhibitors (eculizumab, ravulizumab, crovalimab), 1 C3/C3b inhibitor (pegcetacoplan), 1 factor B inhibitor (iptacopan), and 1 factor D inhibitor used as add-on treatment (danicopan)...Concomitant medications included apixaban, penicillin, and folic acid. In November 2020, her platelets count declined, and a bone marrow evaluation was diagnostic for moderate aplastic anemia (55-65% cellularity for age) and she was started on eltrombopag and cyclosporin. Despite ravulizumab and eltrombopag treatments, the patient developed significant anemia related to extravascular hemolysis (hemoglobin, 5.7 g/dL; LDH, 495 U/L; C5, 26.1 mg/dL [high]; complement hemolytic activity 50 [CH50], 7 U/mL [low])...After receiving both pegcetacoplan and iptacopan for 1 week and rivaroxaban 10 mg once daily for 48 hours, pegcetacoplan treatment ended on May 16, 2024...

Overview of treatment advances with complement inhibitors in patients with paroxysmal nocturnal hemoglobinuria
(ASH 2025)
- P3 | "The success of terminal C5 inhibitors emboldened researchers to investigate proximal complement inhibitors that have the potential to control both IVH and EVH, such as pegcetacoplan (C3/C3b inhibitor) and iptacopan (factor B inhibitor), as well as danicopan (factor D inhibitor) used as an add-on to C5 inhibitors...In the most recent analysis of the phase 3 ALPHA trial (NCT04469465), 57 patients (mean age 53 years) with PNH and residual clinically significant EVH (Hb ≤9.5 g/dL with ARC ≥120 × 10 9 /L) while receiving ravulizumab (63%) or eculizumab (37%) for a mean of 5 years were given danicopan in addition to their current C5 inhibitor for 12 weeks.[Kulasekararaj A, et al...

User experience with pegcetacoplan on-body injector in patients with paroxysmal nocturnal hemoglobinuria
(ASH 2025)
- " Twelve patients with PNH (mean age, 46 years) previously treated with C5is (eculizumab, n=5; ravulizumab, n=7) and on pegcetacoplan for a mean of 18.2 months were recruited; 1 patient who had limited experience with the injector did not complete the interview. Most patients with PNH were satisfied with multiple aspects of their experience with the pegcetacoplan injector. Patients perceived the injector positively as it provides significant benefits, improving their quality of life and reducing treatment burden. Similar on-body delivery systems used by patients with relapsed/refractory multiple myeloma (phase 2 IZALCO and phase 3 IRAKLIA trials) were associated with low infusion-reaction rates, potentially leading to improved long-term adherence, patient quality of life, and practice efficiency [Parmar G, et al."

Low risk for meningococcal and other encapsulated bacteria infections with systemically administered pegcetacoplan in paroxysmal nocturnal hemoglobinuria and C3 glomerulopathies
(ASH 2025)
- P3 | "Clinical benefits of the initially available C5 inhibitors that blocked terminal complement activation (eculizumab, ravulizumab, crovalimab) paved the way for the development of proximal inhibitors, including the C3/C3b inhibitor pegcetacoplan, the factor B inhibitor iptacopan, and the add-on (to C5 inhibitors) factor D inhibitor danicopan. Understanding the safety profile of pegcetacoplan and other complement-targeted therapies, especially the risk for meningococcal and other encapsulated bacteria infections, will help physicians and patients make informed treatment decisions for individuals with complement-mediated conditions. For nearly over 7 years, systemically administered pegcetacoplan has had a consistently low rate of encapsulated bacteria infections in patients with PNH, C3G, or primary IC-MPGN. These findings may reflect effective risk mitigation strategies."

Twelve BTH events were incidentally detected during routine CIadministration; more frequent lab draws may be beneficial for patients with chronic hemolysis. Moredata is needed to understand the BTH rates of different CIs and guide clinicians in BTH management."

CFI is dependent on the presence of cofactors, such as CFH, to regulatecomplement which may explain why upstream CFH levels and not CFI levels rise in BTH. These findingssupport the concept that dynamic changes in CFH may play an active role in the acute regulation ofcomplement during BTH."
