Privigen was evaluated in 2 clinical trials: a 1-year study plus an extension that lasted 2½ years. While taking Privigen, study participants averaged less than one acute serious bacterial infection per year, defined as pneumonia, bacteremia/septicemia, osteomyelitis/septic arthritis, bacterial meningitis, and visceral abscess.

In 1-year study

3.55 infections per
patient per year

0.08 acute serious bacterial

In 2½ year study

1.60 infections per
patient per year

0.02 acute serious bacterial

On average, the participants reported feeling "well."* In the clinical studies, participants recorded how they felt every day.

* Based on personal assessment, patients' overall feeling of well-being score was classified as "well" on a five-point scale (1 = very well, 2 = well, 3 = fair, 4 = poor, 5 = very poor), with a mean of 2.1 ± 0.8 standard deviation.
