Background

Pegcetacoplan is a complement inhibitor indicated in the treatment of paroxysmal nocturnal hemoglobinuria (PNH). Prior to its FDA approval, patients with PNH were typically treated with the C5 inhibiting monoclonal antibody eculizumab. Patients given eculizumab experienced less hemolysis caused by the membrane attack complex, but were still somewhat susceptible to hemolysis caused by C3b opsonization. Pegcetacoplan was developed out of a need for an inhibitor of complement mediated hemolysis further upstream of C5. Pegcetacoplan is a pegylated C3 inhibitor that can disrupt the processes leading to both forms of hemolysis that threaten patients with PNH.

Pegcetacoplan for subcutaneous use was granted FDA approval on 14 May 2021. In February 2023, pegcetacoplan for intravitreal use was approved by the FDA for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration.

Indication

Pegcetacoplan is indicated to treat adults with paroxysmal nocturnal hemoglobinuria (PNH). It is also indicated to treat geographic atrophy (GA) secondary to age-related macular degeneration.

Ruxoprubart Shows Promising Phase II Results as Novel Monotherapy for Paroxysmal Nocturnal Hemoglobinuria

• NovelMed's Ruxoprubart demonstrated significant efficacy in a Phase II trial for treatment-naïve PNH patients, meeting all primary endpoints including complete transfusion avoidance and increased hemoglobin levels. • The drug's selective inhibition of the Alternative Pathway without affecting the Classical Pathway offers a potentially safer profile than existing treatments, which often carry Black Box warnings for infection risk. • With FDA Orphan Drug Designation already secured and plans to file for Breakthrough Therapy Designation, Ruxoprubart is positioned as a potential best-in-class therapy for PNH and other complement-mediated disorders.

Boehringer Ingelheim Launches Phase II Trial of First-in-Class Oral Treatment for Geographic Atrophy

• Boehringer Ingelheim has initiated the JADE Phase II clinical study to evaluate BI 1584862, a potential first-in-class oral treatment for geographic atrophy, a severe form of age-related macular degeneration. • Geographic atrophy affects over 5 million people worldwide with more than 40% considered legally blind, creating a significant unmet need for treatments that can slow disease progression and preserve vision. • The company is simultaneously advancing a second compound, BI 771716, an antibody fragment designed to penetrate retinal layers, demonstrating Boehringer's dual-pathway approach to addressing this debilitating eye condition.

Novartis' FABHALTA Poised to Transform Treatment Landscape for Multiple Complement-Mediated Diseases

• FABHALTA (iptacopan), Novartis' first-in-class oral factor B inhibitor, has received FDA approvals for paroxysmal nocturnal hemoglobinuria (PNH), IgA nephropathy (IgAN), and C3 glomerulopathy (C3G), marking a significant shift from traditional intravenous therapies. • The drug's oral administration route and ability to control both intravascular and extravascular hemolysis addresses key limitations of current therapies, potentially expanding the market for complement-targeted treatments estimated at over $1.2 billion in 2024. • With patent protection extending to 2041 and ongoing investigations for additional indications including myasthenia gravis and atypical hemolytic uremic syndrome, FABHALTA is expected to significantly reshape the complement inhibitor market landscape.

Character Biosciences Secures $93M to Advance Precision Therapies for Age-Related Macular Degeneration

• Character Biosciences has raised $93 million in Series B funding to advance two drug candidates for age-related macular degeneration (AMD) into clinical trials this year. • The company's lead candidates include CTX114, targeting geographic atrophy, and CTX203, designed to prevent progression in intermediate AMD patients by regulating lipid transport. • Character's precision medicine approach involves analyzing data from over 6,500 AMD patients to identify genetic subtypes, potentially improving upon current treatments like Syfovre and Izervay.

Novartis's Fabhalta Rapidly Reshapes PNH Treatment Landscape as Biosimilars Loom

• Fabhalta (Novartis) has gained significant market share in just 15 months since its December 2023 launch, with physician consideration for first-line use doubling year-over-year in the PNH treatment space. • Hematologists increasingly believe all PNH patients should receive complement or factor inhibitor therapy regardless of disease burden, with oral treatment options becoming more attractive due to adherence benefits. • Upcoming biosimilar versions of eculizumab (Bkemv from Amgen and Epysqli from Samsung Bioepis) could disrupt the market, with physicians projecting up to half of Soliris patients may switch by end of 2025.

Zervimesine Shows Promise in Geographic Atrophy Trial, Building on Success in Multiple CNS Disorders

• Cognition Therapeutics' Phase 2 MAGNIFY trial of zervimesine demonstrates slower lesion growth in geographic atrophy patients compared to placebo after 6 months of treatment. • The drug previously showed significant benefits in dementia with Lewy bodies trials, with patients showing 86% improvement in neuropsychiatric symptoms and 62% better motor function versus placebo. • Zervimesine also demonstrated strong results in Alzheimer's disease trials, achieving a 95% reduction in cognitive decline in a biomarker-defined subgroup compared to placebo.

UK Biotech Secures €72M Series A to Advance Novel Gene Therapy for Geographic Atrophy

• Complement Therapeutics has raised €72 million ($79M) in Series A funding to advance CTx001, a single-injection gene therapy targeting geographic atrophy, into Phase 1b clinical trials. • The University of Manchester spinout is developing an AAV-based therapy to address geographic atrophy, an advanced form of AMD affecting 8 million people globally with limited treatment options. • The company has initiated a natural history study (i-GAIN) and partnered with Pharmaron for AAV manufacturing, targeting first-in-human trials in late 2024.

EMA Validates Aspaveli® Extension Application for Rare Kidney Diseases C3G and IC-MPGN

• The European Medicines Agency has validated the application to extend Aspaveli® (pegcetacoplan) use for treating C3 glomerulopathy and primary immune complex membranoproliferative glomerulonephritis, two rare kidney diseases currently lacking approved treatments. • Phase 3 VALIANT study demonstrated significant 68% reduction in proteinuria with pegcetacoplan compared to placebo (p<0.0001), along with stabilization of kidney function and reduced C3c staining intensity. • The potential approval could provide the first targeted treatment for approximately 8,000 European patients affected by these conditions, with possible US launch in second half of 2025.

Astellas Seeks First Japanese Approval for Geographic Atrophy Treatment with Avacincaptad Pegol

• Astellas Pharma has submitted a New Drug Application to Japan's MHLW for avacincaptad pegol, potentially becoming the first approved treatment for geographic atrophy in Japan. • The submission is supported by GATHER1 and GATHER2 clinical trials, which demonstrated the drug's ability to slow GA lesion growth with a favorable safety profile over two years. • Geographic atrophy affects over 5 million people globally, with 66% at risk of becoming legally blind without treatment, highlighting the significant unmet medical need.

Apellis' Syfovre Approved in Australia for Geographic Atrophy
