PANZYGA showed proven results in a clinical trial
A 6-month (24-week) clinical study was done to figure out how well adult patients with CIDP responded to treatment with PANZYGA. In the study, patients were divided into groups, and each group was given a different dose.
The study focused on the 1 g/kg dose, but also looked at the 2 g/kg dose.
PANZYGA improved ability to use arms and walk
*Results are based on improved patient scores in an adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability exam that measures ability to use arms and legs.
