What is Privigen?
Privigen is an intravenous immunoglobulin (IVIg) therapy that contains antibodies—proteins that are part of your immune system. The primary antibody found in Privigen, immunoglobulin G, is the main type of antibody made by your immune system.
Your doctor may refer to your Privigen treatment as "Ig," "intravenous Ig," or "IVIg."
What is chronic immune thrombocytopenic purpura (ITP)?
Chronic ITP is a bleeding disorder lasting longer than 12 months from diagnosis. It occurs when a person's immune system mistakenly attacks and destroys platelets, resulting in very low levels of platelets that can put patients at risk for bruising and/or bleeding. Patients may also experience reddish-purple bruising/spots that look like a rash.
ITP symptoms can include:
- Bruising
- Tiny reddish-purple dots under the skin, known as petechiae
- Larger purple bruising, known as purpura
- Nosebleeds
- Bleeding of the gums
- Heavy menstrual bleeding
- Blood present in the urine or stool
According to the American Society of Hematology, there are 3 types of ITP:
Newly Diagnosed lasts up to 3 months from diagnosis
Persistent lasts 3–12 months from diagnosis
Chronic lasts more than 12 months from diagnosis
Privigen is indicated for the treatment of chronic ITP in patients 15 years or older. At the time of the Privigen pivotal trial, chronic ITP was defined as lasting 6 months or longer, and the disease criteria for that study population followed the earlier (>6 months) definition of chronic ITP.
