EMPAVELI is the first and only FDA-approved medication

for paroxysmal nocturnal hemoglobinuria (PNH) that controls both forms of hemolysis: intravascular hemolysis (IVH) and extravascular hemolysis (EVH).

How EMPAVELI works

How EMPAVELI works

It works higher in the complement system than other treatments, like eculizumab

The complement system

The complement system complement system The complement system, also
referred to as the complement
cascade, is an army of more than
40 different proteins that work
together to get rid of dangerous
cells and fight infection. is a part of your immune system immune system A sophisticated defense
network used to protect the
body from dangers like disease
and infection. and helps your body fight off infections. In the complement system, proteins proteins Molecules that play many
important roles in the body and
can be thought of as the
“workhorses” of cells.

Proteins are required for the
structure, function, and
regulation of the body’s organs
and tissues. work together, creating a chain reaction.

This chain reaction is called the complement cascade.

complement system diagram

C3 C3 A protein located in the blood
that acts as a central point of the
complement system, regulating
its activation. is the central protein in the
chain reaction

EMPAVELI prevents C3 from splitting into
C3a and C3b, helping to stop IVH intravascular hemolysis The destruction of red blood
cells inside a blood vessel. and EVH extravascular hemolysis The destruction of red blood cells
that occurs in the liver or spleen.

C5 C5 A protein located in the blood
that plays an important role in
inflammation and intravascular
hemolysis caused by the
complement system. treatments, like eculizumab, work on C5

EMPAVELI is the only treatment for PNH that targets C3 and may prevent both forms of hemolysis.

INDICATION AND IMPORTANT SAFETY INFORMATION

INDICATION AND IMPORTANT SAFETY INFORMATION

What is EMPAVELI® (pegcetacoplan)?

EMPAVELI is a prescription medicine used to treat adults with a disease called paroxysmal nocturnal hemoglobinuria (PNH).

What is the most important information I should know about EMPAVELI?

EMPAVELI is a medicine that can affect your immune system and can lower the ability of your immune system to fight infections.

  • EMPAVELI may increase your chance of getting serious and life-threatening meningococcal infections that may quickly become life-threatening and cause death if not recognized and treated early.
  • EMPAVELI may also increase the risk of getting serious infections caused by certain bacteria such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. Serious infections may quickly become life-threatening and cause death if not recognized and treated early.
  1. You must be vaccinated against these bacteria at least 2 weeks before your first dose of EMPAVELI if you have not already had these vaccines.
  2. If your healthcare provider decides that urgent treatment with EMPAVELI is needed, you should receive the required vaccinations as soon as possible.
  3. If you have not been vaccinated and EMPAVELI therapy must be initiated immediately, you should also receive 2 weeks of antibiotics with your vaccinations.
  4. If you have been vaccinated against these bacteria in the past, you might need additional vaccinations before starting EMPAVELI. Your healthcare provider will decide if you need additional vaccinations.
  5. Vaccines reduce the risk of serious infections, but do not prevent all serious infections. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a serious infection:
    • fever with or without shivers or the chills
    • fever and a rash
    • shortness of breath
    • extreme pain or discomfort
    • headache with nausea or vomiting
    • high heart rate
    • headache and a fever
    • headache with a stiff neck or stiff back
    • confusion
    • muscle aches with flu-like symptoms
    • clammy skin
    • eyes sensitive to light

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. It is important to show this card to any healthcare provider to 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, give you a Patient Safety Card about your risk of serious infections, and make sure that you are vaccinated.

Who should NOT take EMPAVELI?

Do not take EMPAVELI if you:

  • are allergic to pegcetacoplan or any of the ingredients in EMPAVELI.
  • have not been vaccinated against Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B, unless your healthcare provider decides that urgent treatment with EMPAVELI is needed.
  • have a serious infection caused by the bacteria above.

Before you take EMPAVELI, tell your healthcare provider about all of your medical conditions, including if you:

  • have an infection or fever.
  • are pregnant or plan to become pregnant. EMPAVELI may harm your unborn baby. Females who are able to become pregnant should have a pregnancy test before starting treatment with EMPAVELI and use an effective method of birth control during treatment with EMPAVELI and for 40 days after the final dose.
  • are breastfeeding or plan to breastfeed. It is not known if EMPAVELI passes into your breast milk. You should not breastfeed during treatment with EMPAVELI and for 40 days after the final dose.

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.

If you stop taking EMPAVELI, your healthcare provider will need to monitor you closely for at least 8 weeks after stopping EMPAVELI. Stopping treatment with EMPAVELI may cause a breakdown of red blood cells due to PNH.

Symptoms or problems that can happen due to red blood cell breakdown include:

  • decreased hemoglobin level in your blood
  • blood in your urine
  • shortness of breath
  • trouble swallowing
  • tiredness
  • pain in the stomach (abdomen)
  • blood clots
  • erectile dysfunction (ED)

What are the possible side effects of EMPAVELI?

EMPAVELI can cause serious side effects including allergic reactions. Allergic reactions can happen during your EMPAVELI infusion. Stop your EMPAVELI infusion and tell your healthcare provider or get emergency medical care right away if you get any of these symptoms during your EMPAVELI infusion:

  • chest pain
  • trouble breathing or shortness of breath
  • swelling of your face, tongue, or throat
  • feel faint or pass out

The most common side effects in people with PNH treated with EMPAVELI include injection-site reactions, infections, diarrhea, pain in the stomach (abdomen), respiratory tract infection, viral infection, and tiredness.

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.
