Question 1

What is Empaveli?

Accepted Answer

Empaveli is a targeted therapy known as a complement inhibitor. It works by binding to the complement protein C3, which is a key component of the body's innate immune system. By regulating this protein, the medication helps control the immune response that leads to the breakdown of red blood cells.

This treatment is designed to manage conditions where the immune system mistakenly attacks healthy blood cells. By blocking the activation of the complement cascade at the C3 level, it helps maintain healthier levels of red blood cells within the body.

Question 2

What is Empaveli used for?

Accepted Answer

Empaveli is used to treat paroxysmal nocturnal hemoglobinuria .

Question 3

How does Empaveli work?

Accepted Answer

Targeting the Complement System

Empaveli belongs to a class of medications called complement inhibitors. In people with PNH, a part of the immune system known as the complement system mistakenly attacks and destroys red blood cells. This process of red blood cell destruction is called hemolysis.

Blocking the C3 Protein

The medication works by binding to a protein called C3, which is a central component of the complement system. By blocking C3, Empaveli prevents the immune system from starting the chain reaction that leads to the destruction of red blood cells. This helps control two types of cell destruction:

Intravascular hemolysis: This is the breakdown of red blood cells that occurs inside the blood vessels.

Extravascular hemolysis: This is the destruction of red blood cells that occurs in the spleen or liver.

By reducing the breakdown of red blood cells, Empaveli helps increase hemoglobin levels in the blood and may reduce the frequency of blood transfusions for people with this condition.

Question 7

What is the dosage of Empaveli and how do I take it?

Accepted Answer

Administration Method

Empaveli is given as an infusion under the skin (subcutaneously). It is typically administered twice a week. A healthcare provider will provide training on how to prepare and inject the medication so that it can be used at home by the patient or a caregiver. This process involves using a specialized infusion pump to deliver the medicine over a period of time.

Injection Sites

Common areas for injection include the abdomen, thighs, or upper arms. It is important to rotate the injection site with each dose. Avoid injecting into areas where the skin is tender, bruised, red, or hard.

Preparation

The medication should be removed from the refrigerator and allowed to reach room temperature naturally before use. The solution should be inspected before administration; it should be clear and colorless to slightly yellowish. Do not shake the vial, and do not use the medication if it contains visible particles or appears cloudy.

Missed Doses

If a dose is missed, it should be administered as soon as possible. However, if it is almost time for the next scheduled dose, the missed dose should be skipped, and the regular schedule should be resumed. Do not use two doses at the same time to make up for a missed one.

Question 8

Is Empaveli safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There is limited information regarding the safety of Empaveli in pregnant women. Animal studies have indicated that the medication may increase the risk of pregnancy loss when administered at high doses. Consequently, healthcare providers generally advise individuals who can become pregnant to use effective contraception during treatment and for at least 4 weeks following the last dose.

If you are pregnant or planning to become pregnant, discuss the potential risks and benefits of this medication with your healthcare provider.

Breastfeeding

It is currently unknown whether Empaveli passes into human breast milk or how it might affect a nursing infant. Because of the potential for adverse effects, it is important to consult with a healthcare provider to decide whether to continue breastfeeding or to stop the medication, based on the mother's medical needs.

Question 10

What is the FDA approval status of Empaveli?

Accepted Answer

FDA Approval Status

The U.S. Food and Drug Administration (FDA) approved Empaveli (pegcetacoplan) in May 2021. It was the first FDA-approved PNH therapy that binds to complement protein C3 to help prevent the destruction of red blood cells. It is specifically indicated for use in adults with PNH.

Boxed Warning

Empaveli carries a Boxed Warning regarding the risk of serious and life-threatening infections caused by encapsulated bacteria. These include:

Streptococcus pneumoniae

Neisseria meningitidis (types A, C, W, Y, and B)

Haemophilus influenzae type b (Hib)

To reduce this risk, patients must be vaccinated against these bacteria at least two weeks before starting treatment. If urgent treatment is required and vaccines are not up to date, healthcare providers must provide antibacterial drug prophylaxis.

REMS Program

Because of the risk of serious infections, Empaveli is available only through a restricted program called the Empaveli Risk Evaluation and Mitigation Strategy (REMS). Under this program, healthcare providers who prescribe the medication must be specially certified and must counsel patients about the risks of infection and the importance of vaccination.
