Official title
Phase 2, Randomized, Patient- and Rater-blinded Single-site Trial Evaluating Safety and Efficacy of Efgartigimod in Patients With Guillain-Barré Syndrome.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to evaluate the safety and effectiveness of Efgartigimod in patients with Guillain-Barre syndrome (GBS). The main questions it aims to answer are: * Is Efgartigimod a safe treatment option for GBS patients? * Does treatment with Efgartigimod improve patient outcomes? In addition to standard-of-care procedures and assessments, participants will: * Undergo seven blood draws during hospitalization and in four follow-up study visits to evaluate the concentration of neurofilament light chain, a protein that is elevated in patients with Guillain-Barré syndrome. The presence of neurofilament light chain is believed to be indicative of damage to the nervous system, with higher levels resulting from greater damage. * Complete the Columbia Suicide Severity Rating Scale (C-SSRS) to monitor any suicidal ideation or behaviors during the course of the study.
