Pegcetacoplan-induced remission in pediatric immune-complex membranoproliferative glomerulonephritis with comorbid autosomal recessive polycystic kidney disease: a case report.
(PubMed, Front Med (Lausanne))
- "Initial treatment with prednisolone and mycophenolate mofetil failed to halt disease progression, and the patient became dialysis dependent. To our knowledge, this is the first pediatric case of IC-MPGN with genetically confirmed ARPKD successfully treated with pegcetacoplan. The case illustrates that renal recovery occurred following initiation of proximal complement inhibition with pegcetacoplan."

A pediatric case of C3 glomerulonephritis initially misclassified as IgA nephropathy with a favorable response to C3-targeted therapy.
(PubMed, Pediatr Nephrol)
- "Despite standard immunosuppressive treatment with prednisone and mycophenolic acid plus angiotensin-converting enzyme inhibitors, she achieved only partial remission and subsequently relapsed, exhibiting severe, persistent C3 consumption (6-8 mg/dl) and sustained C5b9 activation (1059 ng/ml)...After 1 year and 9 months without response to immunosuppressive treatment, the C3 inhibitor pegcetacoplan was initiated...This case highlights the inherent diagnostic complexity of C3GN, suggesting the critical role of repeat biopsies in treatment-refractory, complement-dysregulated glomerulonephritis. It strongly supports the potential efficacy of C3 inhibition as a targeted therapeutic approach for patients with C3GN."

Novel drug development for geographic atrophy.

- "A marked important therapeutic milestone with the first FDA approvals of complement inhibitors, Pegcetacoplan and Avacincaptad pegol, demonstrated a modest but statistically significant slowing of lesion growth...Key challenges include treatment burden associated with frequent intravitreal injections, safety considerations, and the persistent disconnect between anatomic endpoints and functional outcomes. These underscore the necessity for future treatments that not only alter disease anatomy but also effectively preserve patients' vision and improve their quality of life."

Low Risk for Meningococcal Infections with Systemically Administered Pegcetacoplan, a Complement C3 and C3b Inhibitor
(THSNA 2026)
- P3 | "Clinical benefits of the initially available C5 inhibitors that block 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 will help physicians and patients make informed treatment decisions for individuals with complement-mediated conditions. For over 7 years of total systemic pegcetacoplan exposure, no cases of encapsulated N. meningitidis and consistently low rates of infections by other encapsulated bacteria were observed in patients with PNH, C3G, primary IC-MPGN, or other conditions. These findings may reflect effective risk mitigation strategies."

Severe systemic lupus erythematosus with thrombotic microangiopathy: rescue therapy with pegcetacoplan.
(PubMed, Pediatr Nephrol)
- "This report describes the case of a 12-year-old female patient with severe lupus nephritis and refractory thrombotic microangiopathy, who required dialysis for several months despite receiving intensive immunosuppressive treatment, including terminal complement blockade with eculizumab. After more than 8 months of haemodialysis, the patient could be weaned off dialysis. This case study highlights the therapeutic potential of pegcetacoplan in the treatment of thrombotic microangiopathy in systemic lupus erythematosus."

Pegcetacoplan for 52 weeks results in sustained proteinuria reduction to remission (≤0.5 g/g) and normalisation (≤0.2 g/g): Phase 3 VALIANT trial
(UKKW 2026)
- P3 | "At week 26, 20 (31.8%) pegcetacoplan-to-pegcetacoplan patients achieved proteinuria remission (≤0.5 g/g); 11 (17.5%) achieved proteinuria normalisation (≤0.2 g/g) (Figure). Results were maintained at week 52, with 23 (36.5%) and 11 (17.5%) achieving proteinuria remission and proteinuria normalisation, respectively. Similar results were seen at week 52 in placebo-to-pegcetacoplan patients with 20 (32.8%) achieving remission and 7 (11.5%) achieving normalisation (following switch to pegcetacoplan from placebo at week 26)."

CASE REPORT: THE USE OF PEGCETACOPLAN PERI-HAEMATOPOIETIC STEM CELL TRANSPLANT FOR PAROXYSMAL NOCTURNAL HAEMOGLOBINURIA / APLASTIC ANAEMIA
(EBMT 2026)
- "She did not have an adult fully matched sibling donor so underwent immunosuppression with horse anti-thymocyte globulin (hATG), cyclosporin and eltrombopag...The conditioning regimen consisted of rATG, fludarabine, cyclophosphamide and one fraction of 2.00 Gy total body irradiation as per the protocol by DeZern et al (Blood 2023)... Use of eculizumab during the peri-transplant period has been described. We are not aware of any previously described cases of pegcetacoplan as a bridging therapy to allograft for patients with PNH and AA. The case demonstrates that this novel complement inhibitor can be used during the transplant conditioning and continued after stem cell infusion with successful engraftment and clearance of the PNH clone."

Pediatric Complement 3 Glomerulonephritis (C3GN) Responsive to Mycophenolate mofetil
(NKF-SCM 2026)
- "Prednisone (2 mg/Kg/day) and Lisinopril were started at 1.5 months...As UPCR remains elevated (~4.09 mg/mg), empagliflozin was added...RESULTS/CASE DISCUSSION Despite the availability of Pegcetacoplan or Iptacopan, these are not currently approved for children under 12 years of age. Complement inhibitors including Eculizumab/ Ravuluzimab will carry potential life threatening risk of infections. CONCLUSION This case highlights MMF as a viable long-term management strategy in refractory C3GN in young patients intolerant or resistant to corticosteroids."

Comparative Efficacy of Complement Inhibitors in Complement Inhibitor-Naïve PNH: A Systematic Review With Supportive Exploratory Network Meta-Analysis of Randomized Trials.
(PubMed, EJHaem)
- "A total of four randomized controlled trials evaluating four complement inhibitor agents (ravulizumab, crovalimab, eculizumab and pegcetacoplan) were included in this systematic review and network meta-analysis, involving 589 complement inhibitor-naïve adults with PNH. However, the evidence network is sparse (four trials) and the cross-trial differences limit reliable inference regarding relative efficacy between active agents. Comparative findings should be interpreted as hypothesis-generating."

ECONOMIC EVALUATION OF PEGCETACOPLAN FOR PNH FROM THE BRAZILIAN PUBLIC HEALTHCARE SYSTEM PERSPECTIVE

From the Brazilian Public Healthcare System perspective, pegcetacoplan represents a cost-saving therapeutic strategy for PNH, yielding lower long-term treatment costs than available C5 inhibitors and offering meaningful reduction in projected national expenditures. These findings support pegcetacoplan as an economically advantageous option for managing previously treated PNH patients."
