Privigen provides immunoglobulin G (IgG) antibodies that may help block your immune system from attacking the protective myelin covering of nerves in the arms, legs, hands, and feet. Even so, exactly how Privigen works is not completely understood.
Two clinical studies, named PRIMA and PATH, demonstrated that Privigen is an effective treatment for CIDP
PRIMA was the first clinical trial to evaluate the use of Privigen in 28 adult patients with CIDP. Thirteen patients had previously received IVIg treatment, and 15 patients had not previously received any treatment for their CIDP.
The PATH study was the second clinical trial, and the largest IgG study in CIDP to date, to evaluate the use of Privigen in 207 adults with CIDP who had previously been treated with and were dependant on IVIg.
In both studies, all patients received a Privigen loading dose of 2 g/kg followed by PRIVIGEN maintenance doses of 1 g/kg for up to 21 weeks with a 3 week follow up period.

Two patients in the PRIMA study and 8 patients in PATH had serious side effects. These included hemolysis (breakdown of red blood cells[2]), breakdown of red blood cells (2), exacerbation of CIDP (2), acute rash, increased blood pressure, hypersensitivity, blood clot in the lung, respiratory failure, and migraine.
These are not the only side effects possible; see the full prescribing information, including boxed warning, for a complete list of adverse reactions possible with treatment for each condition.
