Novel treatment strategies for C3 glomerulopathy: complement blockade.
(PubMed, Int Urol Nephrol)
- "Successful use of eculizumab has been reported in aggressive disease forms...New agents such as iptacopan and pegcetacoplan look very promising. Notably, use of both agents was recently approved by the United States Food and Drug Administration. Herein we review novel treatment strategies for patients suffering from C3G with a focus on agents targeting complement system."

Real-world data on breakthrough hemolysis in patients with paroxysmal nocturnal hemoglobinuria treated with proximal and terminal complement inhibitors.
(ASH 2025)
- "Four patients were treated with factor D inhibitor danicopan(n=3) or iptacopan (n=1) concurrently with ravulizumab.A total of 49 BTH events were identified; while on eculizumab (26 events, 12 patients), ravulizumab (14events, 7 patients), ravulizumab and danicopan (6 events, 3 patients), pegcetacoplan (1 event, 1 patient),zilucoplan (2 events, 2 patients), and no events while on iptacopan. 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."

Pegcetacoplan for patients with transplant-associated thrombotic microangiopathy treatment: A real-world report of six cases
(ASH 2025)
- "This cohort included one patient refractory to plasmaexchange and another who had failed both eculizumab and ravulizumab. This case series provides the first real-world evidence suggesting that proximal C3 inhibitionwith pegcetacoplan may be an effective and safe therapeutic option for pediatric TA-TMA. Treatment wasassociated with rapid and complete remissions, including in patients refractory to C5 inhibitors and otherconventional therapies. These encouraging findings support the investigation of pegcetacoplan inprospective clinical trials to formally establish its role in the management of this severe HSCTcomplication."

Iptacopan monotherapy demonstrated improved clinical outcomes in a real-world cohort with paroxysmal nocturnal hemoglobinuria: Evidence from a managed access program
(ASH 2025)
- "The proportion of pts previously treated witheculizumab, ravulizumab, pegcetacoplan, and danicopan was 71.6%, 37.9%, 13.7%, and 6.3%,respectively. The updated data from this MAP confirm hematological and clinical improvements withiptacopan in Ci-naive and Ci-experienced pts with PNH, with approximately 6 months of iptacopantherapy. Oral iptacopan monotherapy led to normalization of Hb and LDH level, and RLC, along with ahigher proportion of pts achieving transfusion avoidance at retreatment visits compared to BL. Pts alsoreported notable improvements in fatigue and tx satisfaction."

Maternal and fetal pharmacokinetics (PK) of pegcetacoplan in paroxysmal nocturnal hemoglobinuria (PNH): A case report of use in pregnancy
(ASH 2025)
- "Aftertrials of vemircopan and iptacopan, she was transitioned to pegcetacoplan 1080 mg subcutaneous2x/week and achieved transfusion independence (hemoglobin ~110 g/L)...Thesefindings are consistent with preclinical non-human animal data and pegcetacoplan's physicochemicalproperties—a large, pegylated, and hydrophilic cyclic peptide, expected to have limited membranepermeability.In a patient with hemolytic PNH and inadequate hematologic response to eculizumab, conception onpegcetacoplan was not associated with adverse fetal/pregnancy outcomes, and third-trimesterreinitiation resulted in rapid hematologic improvement, transfusion independence, and anuncomplicated peripartum course.In conclusion, this report provides the first clinical and PK evidence suggesting that third-trimester use ofpegcetacoplan may be a viable treatment option in select pregnant patients with PNH with suboptimalresponse to C5 inhibitors.

The effect of breakthrough hemolysis on complement factor h and factor I levels in paroxysmal nocturnal hemoglobinuria
(ASH 2025)
- "Patients were grouped according to CI at sampling; untreated [n=16],eculizumab [n=10], ravulizumab [n=15], pegcetacoplan [n=16], iptacopan [n=15]). 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."

Paroxysmal Nocturnal Hemoglobinuria in Pregnancy Treated With Pegcetacoplan: Case Report and Pharmacokinetic Analysis.
(PubMed, EJHaem)
- "In a patient with transfusion-dependent anemia on eculizumab, third-trimester initiation of pegcetacoplan led to hematological stabilization, transfusion independence, and an uncomplicated term cesarean delivery of a healthy infant. Pegcetacoplan was undetectable in cord blood and breast milk despite therapeutic maternal levels, suggesting fetal and neonatal safety due to lack of significant placental and lactational transfer, and advancing evidence for pegcetacoplan use in pregnancy. Trial Registration: The authors have confirmed clinical trial registration is not needed for this submission."

Navigating the complement cascade: A multicenter journey from pegcetacoplan to iptacopan in paroxysmal nocturnal hemoglobinuria
(ASH 2025)
- "This first multicenter real-world analysis demonstrates that the pegcetacoplan-to-iptacopantransition provides clinical benefit in the majority of this initial set of patients with PNH, with significantimprovements in hemoglobin and an excellent safety profile while maintaining clone stability. The highacceptance rate suggests that patients prefer oral therapy over subcutaneous administration. Thesefindings address a critical knowledge gap in proximal complement inhibitor sequencing, suggesting thatiptacopan is an effective therapeutic option for patients with inadequate pegcetacoplan response andsupporting the development of evidence-based treatment algorithms for optimal PNH care in the era ofmultiple complement inhibitor options."

- "In the 50 patients who switched, 60%transitioned from ravulizumab, 30% from pegcetacoplan, 8% from eculizumab, and 2% fromravulizumab and danicopan. In this real-world cohort, iptacopan provided substantial and durable hemoglobinimprovement across naive and previously treated patients with PNH, with meaningful reduction inhemolytic parameters, absence of thrombosis, and low BTH rate predominantly linked to infection.Patients with previous satisfactory responses also showed improved Hgb levels. The favorable safetyprofile and high treatment persistence underscore iptacopan's role as an effective first-line or switchtherapy and support its incorporation into evidence-based sequencing algorithms in the evolving PNHtreatment landscape."

Real-world treatment patterns and clinical outcomes among patients with paroxysmal nocturnal hemoglobinuria treated with iptacopan in the United States
(ASH 2025)
- "Overall, 25% of patients (n=13) were complementinhibitor (CI) naive at the time of iptacopan initiation, while 75% (n=39) were treatment experienced andhad received ≥1 prior CI therapy for PNH (77% ravulizumab, 46% eculizumab, 26% pegcetacoplan). These data represent early insights into the real-world use of iptacopan and related Hbresponse in US patients with PNH. Adherence to iptacopan was high, and iptacopan treatment improvedHb and LDH parameters, providing comprehensive hemolysis control. Enrollment is currently ongoing; data on additional patients with longer follow-up are forthcoming."

Comparative efficacy of complement inhibitors in complement Inhibitor–Naïve PNH: A network meta-analysis of randomized trials
(ASH 2025)
- "A frequentist model network meta-analyses were conducted in RStudio (v5.4.1) using acommon-effects model. A total of 4 randomized controlled trials evaluating 4 complement inhibitor agents (Ravulizumab,Crovalimab, Eculizumab & Pegcetacoplan) were included in this meta-analysis, involving 589 complementinhibitor–naïve adults with PNH. We found no single agent being consistently superior to others across all clinically relevantoutcomes. Notably, the treatment of choice should be individualized based on the goals of care andpriorities of the patients such as transfusion independence or quality of life. Post-market real-worldanalysis and comparison of these agents may guide optimal sequencing or cost-effective strategies in themanagement of PNH."

A targeted search was conducted in June 2025 for PNH treatments approved since 2020 (iptacopan, pegcetacoplan, danicopan, crovalimab) across five HTA body websites (NICE, GBA, HAS, TLV, Medicinrådet). Novel ISPOR value elements were included in CSs and CRs with qualitative supporting data, however costs and QALYs remained the primary focus. Research and efforts from companies/HTA bodies are needed to generate supporting data and facilitate adoption of broader value elements in decision-making, particularly in rare diseases."
