About XEMBIFY
What is XEMBIFY?
XEMBIFY is a 20% subcutaneous immune globulin (SCIG) replacement therapy used to treat PI (primary humoral immunodeficiency disease) in patients 2 years of age and older.
Why XEMBIFY?
Learn more about why XEMBIFY may be right for you with our Xplainer video series:
What's the difference between subcutaneous IG therapy and intravenous IG therapy?
Subcutaneous immune globulin (SCIG) is administered just under the skin while intravenous immune globulin (IVIG) therapy is administered through a vein. Different IG products have different concentrations. This means they may require more or less volume to be infused. XEMBIFY is a 20% SCIG replacement therapy used to treat PI in patients 2 years of age and older.

Can XEMBIFY only be used subcutaneously?
XEMBIFY is a subcutaneous immune globulin (SCIG) replacement therapy used to treat PI in patients 2 years of age and older. XEMBIFY can only be administered by subcutaneous infusion. Some patients infuse XEMBIFY as often as every day, while other patients infuse once per week. Talk to your doctor about your infusion schedule.
Hear Joanne, who is a nurse with PI, describe her experience with XEMBIFY and how she learned about self-infusion.
How is XEMBIFY made?
XEMBIFY is made from human plasma that is donated by healthy people. It contains antibodies collected from these healthy people that replace the missing or ineffective antibodies in PI patients. The plasma is purified through a unique manufacturing process known as caprylate/chromatography, which results in a product with maximum percentage of IgG protein to fight infections.
Are there any additives or preservatives included in XEMBIFY?
No, XEMBIFY contains no preservatives.
How well does XEMBIFY work?
In a clinical study, people taking XEMBIFY saw improvement in their symptoms of PI and the impact PI had on their lives. Within a year, people taking XEMBIFY experienced:
- 0 serious bacterial infections1*â€
- Less than 3 days of missed work/school1
- 0 hospitalizations due to infections1â€
How well is XEMBIFY tolerated?
The most common side effects in a clinical study with PI patients who received XEMBIFY were2:
- Infusion-site reactions such as redness, pain, puffiness, swelling, bruising, nodule or scab formation, itching, and firmness
- Cough and diarrhea
- Side-effect rates for cough and diarrhea were low, with only 4 events of cough per 1000 infusions and 3 events of diarrhea per 1000 infusions
Tell your healthcare provider if you have or ever had:
- A serious reaction to other medicines that contain immune globulin
- An immunoglobulin A (IgA) deficiency
- A history of heart or blood vessel disease
- Blood clots or "thick blood"
- Inability to move for some time
Can XEMBIFY be used during pregnancy?
It is not known whether XEMBIFY can cause fetal harm when administered to a pregnant woman or if it can affect reproduction. Talk to your doctor if you are pregnant or may become pregnant.
Subcutaneous IG Therapy
Can I self-administer XEMBIFY?
Most patients or caregivers can be trained to infuse. However, self-administration should be done only after you go through self-infusion training with a healthcare professional. Your specialty pharmacy will provide nurse support to train you to infuse.
You can ask your healthcare provider questions about self-administration, especially if you need a refresher or if your infusion schedule has recently changed. Learn more about how to infuse XEMBIFY.
After I am trained on self-administration, will I still need to visit my healthcare provider?
Yes. It's important to work with your healthcare provider when receiving SCIG therapy. Regular healthcare provider visits are an important part of getting the most out of treatment. At each visit, your healthcare provider will review your treatment regimen, evaluate your response to treatment, and address any concerns you may have. It's important to bring your Infusion Log Book with you when you visit your healthcare provider.
What equipment do I need to start self-infusing XEMBIFY?
If you receive your product and supplies through a specialty pharmacy, they will provide your supplies for infusing XEMBIFY including an infusion pump, needle set(s), and tubing. Both your specialty pharmacy nurse and healthcare provider can explain how to use your supplies (including needle size) and infuse XEMBIFY, along with other equipment choices.
You can also access the infusion-related resources included in the XEMBIFY Patient Starter Kit. Learn more about infusion resources.
How many infusion sites should be used?
XEMBIFY may be given in 1 to 6 infusion sites with guidance from a healthcare provider. Most patients in the XEMBIFY clinical trials used 4, although fewer may also be used.

Primary Humoral Immunodeficiency Disease (PI)
What is PI?
PI stands for primary humoral immunodeficiency disease. There are more than 450 different kinds of PI. When you have PI, part of your immune system, which is what protects you from infections and fights off diseases, is missing or doesn't function properly. As a result, your body can't protect you from germs as well as it should, so you are more likely to develop infections and be sick more often. Learn more about PI.3
Hear Joanne, a PI patient and retired registered nurse, describe her journey to getting diagnosed with PI.
What causes PI?
Primary immunodeficiency disorders occur when parts of the immune system (such as certain cells ​or antibodies) are either not working properly, too low, or missing altogether.3,4
What are symptoms of PI?
The signs and symptoms of PI vary from person to person. The most common symptoms include3,4:
- Chronic, recurring infections that are more severe, longer lasting, and more difficult to cure, such as sinus infections, when compared to people with healthy immune systems
- Frequently getting sick with infections, such as a common cold, that a healthy immune system would normally be able to fight off
- Autoimmune problems, such as autoimmune lung or skin disease, which happen when the immune system attacks the body's own organs. Other issues include anemia, celiac disease, arthritis, lupus, and thyroid disorders
Can I catch PI? Is PI contagious?
PI is not contagious; you can't catch it from someone else. PI is usually inherited, which means it is carried through the genes of your parents. If you have the disease, you might pass it along to your children, but you won't give it to anyone else.2,3
What medications are used to treat PI?
There are more than 450 types of primary immunodeficiency. For PI disorders that affect antibody production, doctors may recommend immune globulin replacement therapy.3 Over-the-counter drugs such as aspirin, decongestants, and/or expectorants are used to treat symptoms. Antibiotics are also used to treat infections and deal with a wide range of germs that have a greater impact on people with PI.4
Other treatments may also be available.4
What is immune globulin (IG)?
IG stands for immune globulin. Immune globulin, or IG, is a medicine made from proteins from human plasma, taken from healthy donors, and contains purified antibodies. Plasma is the liquid part of the blood that contains antibodies needed to keep the body healthy.
Immune globulin is given to people with PI to replace missing or ineffective proteins to help the immune system protect against germs and other threats. It is sometimes referred to as IG replacement therapy.

What's the difference between subcutaneous IG therapy and intravenous IG therapy?
Subcutaneous immune globulin (SCIG) is administered under the skin while intravenous immune globulin (IVIG) therapy is administered through a vein. Different IG products have different concentrations. This means they may require more or less volume to be infused. XEMBIFY is an SCIG replacement treatment used to treat PI in patients 2 years of age and older.

What is XEMBIFY®?
XEMBIFY® (immune globulin subcutaneous human–klhw) is a 20% immune globulin used in the treatment of primary humoral immunodeficiency disease (PIDD) in patients 2 years of age and older. XEMBIFY is for subcutaneous administration only.
IMPORTANT SAFETY INFORMATION
WARNING: THROMBOSIS
- Thrombosis (formation of blood clots within blood vessels) may occur with immune globulin products, including XEMBIFY. Before you take XEMBIFY, talk to your doctor if you:
- Are older
- Are sedentary (need to lie down or sit down) for long periods of time
- Are taking estrogen-containing medicines (birth control pills, hormone replacement therapy)
- Have a permanent intravenous (IV) catheter
- Have hyperviscosity of the blood (diseases such as multiple myeloma or other causes of elevated proteins in the blood)
- Have cardiovascular (heart) problems or previous history of stroke
- Thrombosis may occur even if you don't have any risk factors
- If you are at risk of thrombosis, your doctor may prescribe XEMBIFY at the minimum dose and infusion rate. Make sure you drink plenty of fluid before taking XEMBIFY. Make sure your doctor is checking you regularly for signs and symptoms of thrombosis and is checking your blood viscosity if you are at risk of hyperviscosity
Who should not use XEMBIFY?
- XEMBIFY should not be used if you have had a severe allergic reaction to human immune globulin, or if you have been told by a doctor that you are IgA deficient and have developed antibodies to IgA and hypersensitivity after exposure to a previous plasma product
What are possible serious side effects of XEMBIFY?
- Hypersensitivity. Severe allergic reactions may occur with immune globulin products, including XEMBIFY. If you have a severe allergic reaction, stop the infusion immediately and get medical attention. XEMBIFY contains IgA. If you have known antibodies to IgA, you may have a greater risk of developing potentially severe allergic reactions
- Aseptic meningitis syndrome (AMS). Aseptic meningitis is a non-infectious inflammation of the membranes that cover the brain. It causes a severe headache syndrome, which may occur with human immune globulin treatment, including XEMBIFY. If you are showing signs and symptoms of AMS, your doctor may conduct a thorough neurological evaluation including spinal tap (sampling fluid which surrounds the spinal cord) to rule out other causes of meningitis. Stopping human immune globulin treatment has resulted in the end of signs and symptoms within several days. Treatment may include analgesics (pain medicines) and/or a special procedure known as a "blood patch" to stop headache
- Kidney problems or failure. Kidney problems or failure may occur with use of human immune globulin products, especially those containing sucrose (sugar). XEMBIFY does not contain sucrose. If you have kidney disease or diabetes with kidney involvement, your doctor should perform a blood test to assess your hydration level and kidney function before beginning immune globulin treatment and at appropriate intervals thereafter. If your doctor determines that kidney function is worsening, they may discontinue treatment
- Hemolysis. Your doctor should monitor you for symptoms of hemolysis (destruction of red blood cells causing anemia, or low red blood cell count). If your doctor suspects hemolysis, they should perform additional tests to confirm
- Transfusion-related acute lung injury (TRALI). TRALI is a rare but serious syndrome characterized by sudden acute respiratory distress following transfusion. If your doctor suspects TRALI, they will monitor you for any other lung issues. TRALI may be managed with oxygen therapy
- Transmissible infectious agents. Because XEMBIFY is made from human blood, it may carry a risk of transmitting infectious agents such as viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. No cases of transmission of viral diseases or CJD have been associated with the use of XEMBIFY
- Interference with lab tests. Because XEMBIFY contains a variety of antibodies, blood tests to determine antibody levels may be falsely elevated. Be sure to tell your doctor or lab technician that you are using XEMBIFY
What are other possible side effects of XEMBIFY?
- In clinical studies of XEMBIFY, some patients experienced local side effects (at the injection site) including pain, redness, puffiness, bruising, nodules, itching, firmness, scabbing and swelling at the site on the skin where the injection occurred. Some patients experienced non-injection-site side effects including cough and diarrhea.
- Use of XEMBIFY may interfere with the immune response to virus vaccines, such as vaccines for measles, mumps, rubella and varicella. Tell your doctor you are taking XEMBIFY before getting vaccinations
Please see full Prescribing Information for XEMBIFY.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
