Question 1

What is Xembify?

Accepted Answer

Xembify is an immunoglobulin therapy derived from human plasma. It is primarily used to help support the immune system in individuals with certain types of primary immunodeficiency disorders. These conditions involve a weakened or malfunctioning immune system, making people more susceptible to infections. Xembify provides antibodies that help the body fight off a range of infections.

Question 2

What is Xembify used for?

Accepted Answer

Xembify is used to treat primary immunodeficiency .

Question 3

How does Xembify work?

Accepted Answer

How Xembify Works

Xembify is a type of medicine called immune globulin. It contains a concentrated amount of immunoglobulin G (IgG), which are antibodies naturally found in human blood. These antibodies are a critical part of the immune system and help the body recognize and neutralize bacteria, viruses, and other foreign substances.

In people with primary humoral immunodeficiency (PI), the body does not produce enough of these antibodies or the antibodies it does produce do not work correctly. This leaves the person more vulnerable to frequent and severe infections.

When Xembify is injected under the skin, it enters the bloodstream and provides the missing IgG. This replacement therapy helps to:

Restore antibody levels to a more normal range.

Improve the body's ability to defend itself against various pathogens.

Reduce the frequency and severity of infections.

Because the body naturally uses up these antibodies over time, regular treatments are necessary to maintain protective levels in the blood.

Question 4

What are the active ingredients in Xembify?

The active ingredient in Xembify is immunoglobulin G .

Question 5

What are the side effects of Xembify?

Accepted Answer

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Xembify?

Accepted Answer

Xembify belongs to the immune globulin drug class.

Question 7

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

Accepted Answer

How Xembify is Administered

Xembify is for subcutaneous use only, meaning it is infused into the fatty tissue just under the skin. It should never be injected into a vein or a muscle. A healthcare provider will determine the appropriate infusion sites, which may include the abdomen, thighs, upper arms, or the side of the hip. It is important to rotate the infusion sites with each treatment.

Preparation Instructions

Before administration, the medication should be allowed to reach room temperature naturally. The vial should not be shaken, as this can damage the proteins in the medicine. Before use, the liquid should be inspected for any cloudiness or particles; the solution should be clear and colorless or pale yellow. If the medicine appears cloudy or contains particles, it should not be used.

Self-Administration

Patients or caregivers can learn to administer Xembify at home using an infusion pump. A healthcare professional will provide training on how to prepare the medicine, use the pump, and manage the infusion sites. Do not attempt to self-infuse until you have been fully trained and feel comfortable with the process.

Missed Dose

If a scheduled infusion is missed, it is important to contact a healthcare provider for guidance on how to adjust the schedule. Do not use extra medicine to make up for a missed dose.

Question 8

Is Xembify safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

It is not known whether Xembify can cause harm to an unborn baby or affect a woman's ability to conceive. There have been no clinical studies conducted in pregnant women, and animal reproduction studies have not been performed with this medication.

Healthcare providers generally only prescribe Xembify during pregnancy if there is a clear medical necessity. If you are pregnant or planning to become pregnant, consult your doctor to discuss the potential risks and benefits of treatment.

Breastfeeding

There is no specific information available on whether Xembify passes into breast milk, how it affects a nursing infant, or its impact on milk production. It is known that maternal antibodies are naturally present in human milk.

The decision to breastfeed while using Xembify should be made in consultation with a healthcare provider. They will help weigh the developmental and health benefits of breastfeeding against the mother's clinical need for the medication and any potential risks to the infant.

Question 9

What forms and strengths does Xembify come in?

Accepted Answer

Xembify is available as a sterile, preservative-free liquid solution. It is intended for subcutaneous administration only. The medication is supplied in single-dose vials.

Question 10

What is the FDA approval status of Xembify?

Accepted Answer

FDA Approval and Indications

The U.S. Food and Drug Administration (FDA) approved Xembify (immune globulin subcutaneous (human) 20%) in July 2019. It is indicated for the treatment of primary humoral immunodeficiency (PI) in adults and pediatric patients 2 years of age and older.

Boxed Warning

Xembify carries a boxed warning regarding the risk of thrombosis (blood clots). Thrombosis may occur with immune globulin products, including Xembify, regardless of the route of administration. Risk factors for developing blood clots include:

Advanced age

Prolonged immobilization

Hypercoagulable conditions

History of venous or arterial thrombosis

Use of estrogens

Indwelling central vascular catheters

Hyperviscosity (thickened blood)

Cardiovascular risk factors

For patients at risk of thrombosis, healthcare providers are advised to administer Xembify at the minimum dose and infusion rate practicable. Patients should be adequately hydrated before administration and monitored for signs and symptoms of thrombosis. Those at risk for hyperviscosity should be assessed for blood viscosity.

Question 11

What should I know about Xembify and cost?

Accepted Answer

Factors Influencing Cost

The total price of Xembify treatment is largely determined by the amount of medication prescribed. Dosage is calculated based on the patient's body weight and their previous intravenous or subcutaneous immune globulin dose. Because Xembify is administered frequently—ranging from daily to weekly—the cumulative volume of the drug used significantly impacts the overall cost.

Insurance and Prior Authorization

As a specialty biologic product, Xembify is typically covered under most insurance plans for the treatment of primary humoral immunodeficiency. However, insurance companies often require prior authorization. This process involves a healthcare provider submitting documentation to prove medical necessity before the insurer agrees to cover the cost of the drug.

Specialty Pharmacy and Distribution

Xembify is generally not available at standard retail pharmacies. It is distributed through specialty pharmacies that handle biologics and provide the necessary supplies for subcutaneous administration. Out-of-pocket costs, such as co-payments or co-insurance, may vary depending on whether the insurance plan processes the claim under medical or pharmacy benefits.

Financial Assistance

Patients may have access to financial support programs to help manage the costs of Xembify. These programs are often provided by the manufacturer and may include co-pay assistance for patients with commercial insurance or patient assistance programs for those who are uninsured or underinsured.
