Research Overview

Glatiramer Acetate

Glatiramer acetate has extensive literature in relapsing-remitting multiple sclerosis, where it is used to shift immune activity away from pro-inflammatory pathways. It remains one of the best-studied peptide-based immunomodulators and a benchmark compound for autoimmunity research.

Pidotimod

Pidotimod has human data in recurrent infections, especially where immune stimulation or reduced infection frequency is the target. Published work commonly reports improvements in phagocyte function, mucosal defense, and fewer respiratory infection episodes.
