Game-changing results across 3 key measures that matter
Doctors track these “key measures” of disease activity to understand how your kidneys are responding to treatment:
Primary goal
High protein in your urine is a sign your kidneys aren’t working well. EMPAVELI significantly lowered proteinuria, which can help slow disease progression.
Kerry, the mother of Quinn who's taken EMPAVELI
“Since Quinn started EMPAVELI, we saw an improvement in his labs...specifically, his
uPCR was significantly reduced. It was surprising and a huge relief all at the same time.”
Individual experiences may vary.
Consistent results lasting 1 year
After 6 months, all participants in the trial received EMPAVELI for an
additional 6 months.
People taking EMPAVELI experienced proteinuria reduction that was maintained throughout 1 year.
After switching from placebo to EMPAVELI, reduction in protein in the urine was also observed but slightly less than what was seen in people who had been taking EMPAVELI from the beginning of the study.
People in this group received placebo for the first 6 months, during which proteinuria increased by 3%. After switching to EMPAVELI, proteinuria was 51% lower than at the start of the study (baseline) at 1 year.

Secondary goals
Kidney composite
endpoint
Nearly half of people saw both stabilization of kidney functionStabilized kidney function/Stabilization of kidney functionStabilization of kidney function was defined as an eGFR reduction of 15% or less. This shows a slower decline in kidney function. and reduction of proteinuriaReduced proteinuria/Reduction of proteinuria:Reduction of proteinuria of 50% or more, indicating less protein is leaking into the urine. at 6 months with EMPAVELI (31 out of 63 people)
compared to 3% of the placebo group (2 out of 61 people)†
eGFR stabilization
Most people had stable kidney function as measured by eGFR at 6 months with EMPAVELI (43 out of 63 people)
compared to 59% of the placebo group
(36 out of 61 people)
Proteinuria reduction
Most people had 50% or more reduction in proteinuria at 6 months with EMPAVELI (38 out of 63 people)
compared to 5% of the placebo group
(3 out of 61 people)
†Kidney composite endpoint. The kidney composite endpoint combines multiple individual indicators of kidney function and disease progression into a single study goal.
Difference in eGFR of
+6.31 mL/min/1.73 m2
between EMPAVELI and placebo
at 6 months
eGFR measures how well your kidneys function. EMPAVELI has been shown to help slow disease progression to protect kidney function.
Kidney function results over 1 year
Most people experience some loss in kidney function as they age. In people with C3G or primary IC-MPGN, this loss can happen more quickly. Reducing the loss of kidney function is an important treatment goal.
EMPAVELI helps to slow down how fast your kidneys lose function with results seen over 1 year.
Difference in eGFR of +6.31 mL/min/1.73 m2 between EMPAVELI and placebo at 6 months
EMPAVELI is a strong move you can make to help reduce the loss of kidney function and slow disease progression
Pharmacodynamic results‡
Of the 69 people with kidney biopsies§, 74% of people (26 out of 35) taking EMPAVELI had reduced C3 fragmentsReduced C3 fragmentsReduced C3 fragment levels may be a sign that the disease is becoming less active. by at least 2 intensity levels at 6 months compared to 12% of the placebo group (4 out of 34)

For illustrative purposes only.
Intensity levels reflect how much C3 is present.
The higher your intensity reduction is, the clearer your kidneys become of C3 fragments.
1-level intensity reduction=10x fewer C3 fragments
2-level intensity reduction=100x fewer C3 fragments
3-level intensity reduction=No detectable C3 fragments

‡Pharmacodynamic data help researchers understand how a medicine affects the body.
§Evaluable patients included only adult patients. Kidney biopsies were not performed on pediatric patients.
C3 staining shows C3 fragment buildup in the kidneys, which can indicate ongoing disease activity. EMPAVELI reduces C3 fragment buildup in the kidneys.

“I noticed a difference after using EMPAVELI. I started to feel like myself again—for the first time in years. My labs reflected the change, and my numbers started improving.”

Results seen in a smaller group of children and teens aged 12 to 17 years
These results are based on a small group and are considered to be exploratory because the
study was not designed to show differences between EMPAVELI and placebo within these groups
of patients. More research is needed to better understand them.
From Day 1 to 6 months
Over half (57.1%) of children
and teens achieved the kidney
composite endpoint with EMPAVELI
(n=28 patients)
compared with 3.7% with placebo
(n=27 patients)

These data are based on an additional analysis of pharmacodynamic data. They were not powered to detect differences between treatment and placebo in these data, and results were not included in the study’s formal multiplicity-controlled testing hierarchy. Therefore, findings should be considered exploratory and interpreted descriptively. No formal statistical conclusions can be drawn.

EMPAVELI is a medicine that affects your immune system and may lower the ability of your immune system to fight infections.
EMPAVELI increases your chance of getting serious infections caused by encapsulated bacteria such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. These serious infections may quickly become life-threatening or cause death if not recognized and treated early.
Your healthcare provider will give you a Patient Safety Card about the risk of serious infections. Carry it with you at all times during treatment and for 2 months after your last EMPAVELI dose. Your risk of serious infections may continue for several weeks after your last dose of EMPAVELI. It is important to show this card to any healthcare provider who treats you. This will help them diagnose and treat you quickly.
EMPAVELI is only available through a program called the EMPAVELI Risk Evaluation and Mitigation Strategy (REMS). Before you can take EMPAVELI, your healthcare provider must enroll in the EMPAVELI REMS program, counsel you about the risk of serious infections caused by certain bacteria, give you information about the symptoms of serious infections, make sure that you are vaccinated against serious infections caused by encapsulated bacteria and that you receive antibiotics if you need to start EMPAVELI right away and you are not up to date on your vaccines, and give you a Patient Safety Card about your risk of serious infections.
Do not take EMPAVELI if you:
Before you take EMPAVELI, tell your healthcare provider about all of your medical conditions, including if you:
Tell your healthcare provider about all the vaccines you receive and medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements which could affect your treatment.
EMPAVELI can cause serious side effects including allergic reactions. Allergic reactions can happen during your EMPAVELI infusion and can be life-threatening. Stop your EMPAVELI infusion and get emergency medical care right away if you get any of these symptoms during your EMPAVELI infusion:
The most common side effects in adults and children 12 years of age and older with C3G or primary IC-MPGN treated with EMPAVELI include injection-site reactions, fever, common cold, flu, cough, and nausea.
These are not all of the possible side effects of EMPAVELI. Tell your healthcare provider about any side effect that bothers you or that does not go away.
Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
EMPAVELI is a prescription medicine used to treat adults and children 12 years of age and older with a kidney disease called complement 3 glomerulopathy (C3G) or primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN), to reduce levels of protein in the urine (proteinuria) and the loss of kidney function.
