Clinical trial experience

For PI

In a study, patients with primary immunodeficiency disorders averaged 0.08 acute serious bacterial infections per year with Privigen—and the rate of other bacterial infections per year with Privigen was 3.55


In 2 separate studies, 61% and 73% of patients with CIDP responded to Privigen treatment. Almost all patients who responded did so after 1 or 2 maintenance treatments*

*At weeks 4 and 7.


In a study in 80.7% of patients with ITP, platelet count increased 150% within 7 days of taking Privigen; platelet counts increased beginning the day after the first infusion and remained high for at least 8.8 days in 75% of patients

What is Privigen IVIg?

Privigen IVIg is an antibody therapy that contains immunoglobulin G (IgG).

  • An antibody is an essential part of the immune system that identifies and destroys disease-causing bacteria or viruses
  • IgG is the main type of antibody made by the immune system

Your doctor may refer to your IgG treatment as “Ig,” “intravenous Ig,” or “IVIg.”

Privigen Safety

  • Thrombosis (blood clotting) can occur with immune globulin products, including Privigen
  • If you are at high risk of thrombosis or kidney problems, your doctor will prescribe and administer Privigen at a reduced dose and infusion rate
  • Inform your physician if you notice early signs of hypersensitivity reactions to administration of Privigen, including hives, tightness of the chest, wheezing, or shock
  • Report to your physician other symptoms that could be signs of adverse reactions to Privigen, including weight gain, shortness of breath, discoloration in arm or leg, excessive fatigue, light sensitivity, and dark‑colored urine
  • Before you receive any vaccine, tell your doctor if you have had a recent Privigen treatment, as the vaccine may not be as effective
  • The risk of transmission of infectious agents, including viruses, cannot be completely eliminated
  • Report to your doctor any symptoms that concern you

What makes Privigen safe

CSL Behring, the maker of Privigen, has a heritage of safety and excellence in therapies derived from plasma (part of the blood) spanning over 65 years. Our quality controls are among the most rigorous in the business, and our products meet exacting standards.

The process used to make Privigen includes a 3-step virus inactivation/removal process:

The Privigen Difference: the Only IVIg Stabilized With Proline

Proline is a naturally occurring amino acid that is made by the body and is found in certain foods. Proline keeps the immunoglobulin stable, even at room temperature. You don't need to refrigerate Privigen, for greater convenience.

People with hyperprolinemia should not use Privigen.

Privigen is ready to use

Privigen is a ready-to-use liquid, which saves time, unlike IVIg products that come as powders that need to be mixed before use.

Privigen is stored at room temperature

Privigen is stored at room temperature, so it’s already ready for use.
