Wellstat ImmunoTherapeutics

Wellstat ImmunoTherapeutics was a private U.S. biotechnology company focused on immune modulation. The company was best known for developing zwitterionic polysaccharides (ZPS), a novel class of carbohydrate-based immune modulators intended for inflammatory and autoimmune diseases by inducing regulatory T-cell responses and local anti-inflammatory cytokine production. Patent records also indicate work on complement factor B-related immunology programs and engineered enveloped virus technologies for cancer treatment. Available evidence suggests the company operated as part of the broader Wellstat group but is no longer active as an operating biotech company. Publicly visible evidence of clinical-stage development is limited, and its programs appear to have remained in preclinical research.
