Immunoglobulin G Therapy Dose Optimization

Optimization of Dosing of Immunoglobulin G in the Obese Population

Source: ClinicalTrials.gov · Last updated 17 Feb 2026

Brief summary (registry, in English)

The overall goal of this proposal is to investigate effects of obesity on pharmacokinetics of immunoglobulin G (IgG) and to develop strategies for optimization of dosing of IgG in obese patients. There is an ongoing debate regarding the most appropriate dosing of IgG formulations in obese patients. Obesity poses significant health risks; and evidence supporting dosing strategies of IgG in obese patients is inadequate. Some of the adverse reactions have been attributed to a relative overdosing in these patients, due to a limited distribution of IgG into fat tissue.
