Pegcetacoplan

The US Food and Drug Administration (FDA) has approved Apellis Pharmaceuticals’ Sobi-partnered Empaveli (pegcetacoplan) to treat two rare kidney diseases. The targeted C3 therapy has been authorised to reduce excess protein in the urine (proteinuria) in patients aged 12 years and older with C3 glomerulopathy (C3G) or primary immune complex membranoproliferative glomerulonephritis (IC-MPGN). C3G and primary IC-MPGN are estimated to affect 5,000 people in the US. Excessive deposits of the C3 protein are a key marker of disease activity in both conditions and can lead to kidney inflammation, damage and failure, with approximately 50% of patients experiencing kidney failure within five to ten years of diagnosis. Empaveli is designed to regulate excessive activation of the complement cascade, a part of the body’s immune system, and is already approved in the US to treat the rare blood disorder paroxysmal nocturnal haemoglobinuria. The FDA’s latest decision was supported by positive results from the late-stage VALIANT trial, in which Empaveli reduced proteinuria by 68% compared to placebo. Empaveli was also associated with stabilisation of kidney function, as measured by estimated glomerular filtration rate, as well as substantial clearance of C3 deposits, assessed by C3 staining. These benefits were consistent across adolescent and adult patients with C3G and primary IC-MPGN, and in C3G patients with post-transplant disease recurrence. Apellis’ co-founder and chief executive officer, Cedric Francois, said: “Empaveli has the potential to be truly transformational for patients with C3G and primary IC-MPGN, who until now have had very few treatment options. “In the largest pivotal study of these diseases, Empaveli demonstrated its potential to preserve kidney function by controlling all three key markers of disease.” Apellis has exclusive commercialisation rights for systemic pegcetacoplan in the US, while Sobi holds these everywhere else. Apellis also has global commercial rights for ophthalmological pegcetacoplan, including for geographic atrophy. Commenting on the latest approval of the drug, lead principal investigator for the VALIANT study, Carla Nester, said: “With standard of care, patients living with these rare and severe diseases frequently progress to kidney failure, necessitating lifelong dialysis and/or a kidney transplant. “Given the urgent need, particularly in children, the approval of Empaveli marks a pivotal moment in the treatment of rare kidney diseases.”

Second Quarter 2025 Financial Results Total Revenue Total revenue was $178.5 million for the second quarter of 2025, which consisted of $150.6 million of SYFOVRE U.S. net product revenue, $20.8 million of EMPAVELI U.S. net product revenue, and $7.1 million in licensing and other revenue associated with the Sobi collaboration. Total revenue was $199.7 million for the second quarter of 2024, which consisted of $154.6 million of SYFOVRE U.S. net product revenue, $24.5 million in EMPAVELI U.S. net product revenue, and $20.5 million in licensing and other revenue associated with the Sobi collaboration. Cost of Sales Cost of sales was $13.6 million for the second quarter 2025, compared to $23.1 million for the same period in 2024. The decrease in cost of sales was primarily driven by lower volumes of product supplied to Sobi and a decrease in expenses incurred related to excess, obsolete or scrapped inventory. The decreases were partially offset by higher volume from commercial sales and product provided under our patient assistance programs, as well as increased costs incurred in connection with cancellable purchase commitments. R&D Expenses R&D expenses were $67.0 million for the second quarter of 2025, compared to $78.0 million for the same period in 2024. The decrease in R&D expenses was primarily driven by lower program-specific and non-program-specific external costs, reduced compensation and related personnel costs, and lower other expenses. Selling, General and Administrative (SG&A) Expenses SG&A expenses were $131.1 million for the second quarter of 2025, compared to $128.1 million for the same period in 2024. The increase in SG&A was primarily driven by higher office and travel expenses, professional and consulting fees, factoring fees, and insurance expenses, partially offset by lower personnel costs. Net Loss Apellis reported a net loss of $42.2 million for the second quarter 2025, compared to a net loss of $37.7 million for the same period in 2024. Cash As of June 30, 2025, Apellis had $370.0 million in cash and cash equivalents, compared to $411.3 million in cash and cash equivalents as of December 31, 2024. Apellis anticipates its cash, combined with expected product revenues and funds from the Sobi royalty purchase agreement, will fund the business to profitability.

About EMPAVELI®/Aspaveli® (pegcetacoplan)EMPAVELI®/Aspaveli® (pegcetacoplan) is a targeted C3 therapy designed to regulate excessive activation of the complement cascade, part of the body’s immune system, which can lead to the onset and progression of many serious diseases. It is approved for the treatment of C3 glomerulopathy (C3G) and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN) in the United States and paroxysmal nocturnal hemoglobinuria (PNH) in the United States, European Union, and other countries globally. The therapy is also under investigation for other rare diseases. About the Apellis and Sobi CollaborationApellis and Sobi have global co-development rights for systemic pegcetacoplan. Sobi has exclusive ex-U.S. commercialization rights for systemic pegcetacoplan, and its opt-in rights for future development programs are unchanged, exercisable at any time prior to commercialization. Apellis has exclusive U.S. commercialization rights for systemic pegcetacoplan and worldwide commercial rights for ophthalmological pegcetacoplan, including for geographic atrophy. U.S. Important Safety Information for SYFOVRE® (pegcetacoplan injection)CONTRAINDICATIONS SYFOVRE is contraindicated in patients with ocular or periocular infections, in patients with active intraocular inflammation, and in patients with hypersensitivity to pegcetacoplan or any of the excipients in SYFOVRE. Systemic hypersensitivity reactions (e.g., anaphylaxis, rash, urticaria) have occurred. WARNINGS AND PRECAUTIONS Endophthalmitis and Retinal Detachments Intravitreal injections, including those with SYFOVRE, may be associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering SYFOVRE to minimize the risk of endophthalmitis. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately. Retinal Vasculitis and/or Retinal Vascular Occlusion Retinal vasculitis and/or retinal vascular occlusion, typically in the presence of intraocular inflammation, have been reported with the use of SYFOVRE. Cases may occur with the first dose of SYFOVRE and may result in severe vision loss. Discontinue treatment with SYFOVRE in patients who develop these events. Patients should be instructed to report any change in vision without delay. Neovascular AMD In clinical trials, use of SYFOVRE was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (12% when administered monthly, 7% when administered every other month and 3% in the control group) by Month 24. Patients receiving SYFOVRE should be monitored for signs of neovascular AMD. In case anti-Vascular Endothelial Growth Factor (anti-VEGF) is required, it should be given separately from SYFOVRE administration. Intraocular Inflammation In clinical trials, use of SYFOVRE was associated with episodes of intraocular inflammation including: vitritis, vitreal cells, iridocyclitis, uveitis, anterior chamber cells, iritis, and anterior chamber flare. After inflammation resolves, patients may resume treatment with SYFOVRE. Increased Intraocular Pressure Acute increase in IOP may occur within minutes of any intravitreal injection, including with SYFOVRE. Perfusion of the optic nerve head should be monitored following the injection and managed as needed. Intravitreal injections, including those with SYFOVRE, may be associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering SYFOVRE to minimize the risk of endophthalmitis. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately.

U.S. Important Safety Information for EMPAVELI® (pegcetacoplan) BOXED WARNING: SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIAEMPAVELI, a complement inhibitor, increases the risk of serious infections, especially those caused by encapsulated bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. Life-threatening and fatal infections with encapsulated bacteria have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early. Complete or update vaccination for encapsulated bacteria at least 2 weeks prior to the first dose of EMPAVELI, unless the risks of delaying therapy with EMPAVELI outweigh the risks of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria in patients receiving a complement inhibitor. Patients receiving EMPAVELI are at increased risk for invasive disease caused by encapsulated bacteria, even if they develop antibodies following vaccination. Monitor patients for early signs and symptoms of serious infections and evaluate immediately if infection is suspected. Because of the risk of serious infections caused by encapsulated bacteria, EMPAVELI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the EMPAVELI REMS. CONTRAINDICATIONS Hypersensitivity to pegcetacoplan or to any of the excipients For initiation in patients with unresolved serious infection caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B WARNINGS AND PRECAUTIONS Serious Infections Caused by Encapsulated Bacteria EMPAVELI, a complement inhibitor, increases a patient’s susceptibility to serious, life-threatening, or fatal infections caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis (caused by any serogroup, including non-groupable strains), and Haemophilus influenzae type B. Life-threatening and fatal infections with encapsulated bacteria have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. The initiation of EMPAVELI treatment is contraindicated in patients with unresolved serious infection caused by encapsulated bacteria. Complete or update vaccination against encapsulated bacteria at least 2 weeks prior to administration of the first dose of EMPAVELI, according to the most current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with EMPAVELI. Note that ACIP recommends an administration schedule in patients receiving complement inhibitors that differs from the administration schedule in the vaccine prescribing information. If urgent EMPAVELI therapy is indicated in a patient who is not up to date with vaccines against encapsulated bacteria according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer these vaccines as soon as possible. The benefits and risks of treatment with EMPAVELI, as well as the benefits and risks of antibacterial drug prophylaxis in unvaccinated or vaccinated patients, must be considered against the known risks for serious infections caused by encapsulated bacteria. Vaccination does not eliminate the risk of serious encapsulated bacterial infections, despite development of antibodies following vaccination. Closely monitor patients for early signs and symptoms of serious infection and evaluate patients immediately if an infection is suspected. Inform patients of these signs and symptoms and instruct patients to seek immediate medical care if these signs and symptoms occur. Promptly treat known infections. Serious infection may become rapidly life-threatening or fatal if not recognized and treated early. Consider interruption of EMPAVELI in patients who are undergoing treatment for serious infections. EMPAVELI is available only through a restricted program under a REMS. EMPAVELI REMS EMPAVELI is available only through a restricted program under a REMS called EMPAVELI REMS, because of the risk of serious infections caused by encapsulated bacteria. Notable requirements of the EMPAVELI REMS include the following: Under the EMPAVELI REMS, prescribers must enroll in the program. Prescribers must counsel patients about the risks, signs, and symptoms of serious infections caused by encapsulated bacteria, provide patients with the REMS educational materials, ensure patients are vaccinated against encapsulated bacteria at least 2 weeks prior to the first dose of EMPAVELI, prescribe antibacterial drug prophylaxis if patients’ vaccine status is not up to date and treatment must be started urgently, and provide instructions to always carry the Patient Safety Card both during treatment, as well as for 2 months following last dose of EMPAVELI. Pharmacies that dispense EMPAVELI must be certified in the EMPAVELI REMS and must verify prescribers are certified. Further information is available at www.empavelirems.com or 1-888-343-7073. Infusion-Related Reactions Systemic hypersensitivity reactions (eg, facial swelling, rash, urticaria, pyrexia) have occurred in patients treated with EMPAVELI, which may resolve after treatment with antihistamines. Cases of anaphylaxis leading to treatment discontinuation have been reported. If a severe hypersensitivity reaction (including anaphylaxis) occurs, discontinue EMPAVELI infusion immediately, institute appropriate treatment, per standard of care, and monitor until signs and symptoms are resolved. Monitoring Paroxysmal Nocturnal Hemoglobinuria (PNH) Manifestations after Discontinuation of EMPAVELI After discontinuing treatment with EMPAVELI, closely monitor for signs and symptoms of hemolysis, identified by elevated LDH levels along with sudden decrease in PNH clone size or hemoglobin, or reappearance of symptoms such as fatigue, hemoglobinuria, abdominal pain, dyspnea, major adverse vascular events (including thrombosis), dysphagia, or erectile dysfunction. Monitor any patient who discontinues EMPAVELI for at least 8 weeks to detect hemolysis and other reactions. If hemolysis, including elevated LDH, occurs after discontinuation of EMPAVELI, consider restarting treatment with EMPAVELI. Interference with Laboratory Tests There may be interference between silica reagents in coagulation panels and EMPAVELI that results in artificially prolonged activated partial thromboplastin time (aPTT); therefore, avoid the use of silica reagents in coagulation panels. ADVERSE REACTIONS Most common adverse reactions in adult patients with PNH (incidence ≥10%) were injection-site reactions, infections, diarrhea, abdominal pain, respiratory tract infection, pain in extremity, hypokalemia, fatigue, viral infection, cough, arthralgia, dizziness, headache, and rash. Most common adverse reactions in adult and pediatric patients 12 years of age and older with C3 glomerulopathy (C3G) or primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN) (incidence ≥10%) were injection-site reactions, pyrexia, nasopharyngitis, influenza, cough, and nausea. USE IN SPECIFIC POPULATIONS Females of Reproductive Potential EMPAVELI may cause embryo-fetal harm when administered to pregnant women. Pregnancy testing is recommended for females of reproductive potential prior to treatment with EMPAVELI. Advise female patients of reproductive potential to use effective contraception during treatment with EMPAVELI and for 40 days after the last dose.
