Randomized, Double Blind, Placebo Controlled, Proof-of-Concept Study to Evaluate the Benefit of RUCONEST in Improving Neurological Symptoms in Post-SARS-CoV-2 Infection.

Patients receiving intravenous immunoglobulin (IVIG) therapy for primary immunodeficiency and neurologic conditions may experience adverse drug reactions (ADRs). The mechanism of the ADR is unknown. Currently, the standard practice for these patients is to change from IV to subcutaneous IG (SCIG) but because of the need of immunomodulation or patient preference, SCIG may not be an option. Data has shown that some levels of complement decrease from pre- to post-infusion of IVIG. This study is to determine if replacing this complement protein may ameliorate ADRs.

This study will evaluate the use of intravenous immunoglobulins (IVIG) at a dose of 1g/Kg/body weight given every three weeks for 6 infusions in pediatric subjects ages 4 - 16 years with moderate to severe PANS. The study will compare biomarkers and behavioral scales before treatment, after the last infusion, 2 months, and at a minimum 6 months post-treatment.
