EMPAVELI 1080 mg/20 mL (Pegcetacoplan) Injection
EMPAVELI (pegcetacoplan) 1080 mg/20 mL injection is a prescription complement inhibitor used in the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in adults and C3 glomerulopathy (C3G) or primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN) in adults and children aged 12 years and older. For C3G and primary IC-MPGN, EMPAVELI is indicated to reduce proteinuria and loss of kidney function.
EMPAVELI contains pegcetacoplan, a targeted complement C3 inhibitor. By binding to complement protein C3 and its activation fragment C3b, pegcetacoplan regulates complement activation and helps control downstream complement activity.

What Is EMPAVELI (Pegcetacoplan) Used For?
EMPAVELI is a prescription medicine indicated for:
Paroxysmal Nocturnal Hemoglobinuria (PNH)
EMPAVELI is indicated for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH).
C3 Glomerulopathy (C3G) and Primary IC-MPGN
EMPAVELI is also indicated for adults and pediatric patients aged 12 years and older with C3 glomerulopathy (C3G) or primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN) to reduce proteinuria and loss of kidney function.
How Does EMPAVELI Work?
EMPAVELI contains pegcetacoplan, which targets the complement system by binding to C3 and C3b. This inhibits complement activation and the generation of downstream complement effectors.
Because complement activation plays an important role in PNH and certain complement-mediated kidney diseases, controlling this pathway can help address disease activity.
Dosage and Administration
The recommended dosage for adults with PNH is 1,080 mg administered subcutaneously twice weekly.
For adults with C3G or primary IC-MPGN, the recommended dosage is also 1,080 mg subcutaneously twice weekly. Pediatric dosing for patients 12 years and older is based on body weight and should follow the prescribing information provided by the treating healthcare professional.
EMPAVELI may be administered using a commercially available infusion pump or the EMPAVELI Injector, according to the prescribed instructions.
Do not change the dose or frequency of EMPAVELI without medical advice.
Important Safety Information
EMPAVELI carries a boxed warning for serious and potentially life-threatening infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B.
Patients should receive appropriate vaccination against encapsulated bacteria before starting treatment when possible, according to current medical recommendations. Patients receiving EMPAVELI remain at increased risk of serious infections and should be monitored for signs and symptoms of infection.
EMPAVELI can also cause infusion-related or allergic reactions. Seek immediate medical attention for symptoms such as difficulty breathing, wheezing, swelling of the face, tongue or throat, chest pain, dizziness, fainting, rapid heartbeat, vomiting, or severe skin reactions.
Common Side Effects
In adults with PNH, commonly reported adverse reactions include:
- Injection-site reactions
- Infections
- Diarrhea
- Abdominal pain
- Respiratory tract infections
- Pain in the extremities
- Low potassium levels
- Fatigue
- Viral infections
- Cough
- Joint pain
- Dizziness
- Headache
- Rash
In adults and children 12 years and older treated for C3G or primary IC-MPGN, commonly reported adverse reactions include injection-site reactions, fever, nasopharyngitis, influenza, cough, and nausea.
Why Is EMPAVELI Prescribed?
EMPAVELI provides targeted inhibition of the complement C3 pathway and is an established treatment option for adults with PNH and for patients aged 12 years and older with C3G or primary IC-MPGN under the applicable prescribing information.
Treatment should be initiated and monitored by a qualified healthcare professional familiar with complement-mediated disorders.
