Study Overview
Brief Summary
RED4MS is a clinical trial to assess the safety and tolerability of autologous peptide coupled red blood cells (CLS12311) in patients with relapsing remitting multiple sclerosis (RRMS). CLS12311 consists of autologous red blood cells (RBCs) coupled with antigenic peptides and aims to treat RRMS by induction of antigen-specific immune tolerance.
Detailed Description
The RED4MS trial is designed as an open-label, dose-escalation phase Ib study, enrolling 9 RRMS patients in three ascending dose groups. The first patient (sentinel) in each dose group will receive one cycle of the therapy, while the remaining patients will receive two treatment cycles.
