Problem
Current treatments for chronic autoimmune and inflammatory diseases, including transplant rejection and graft-versus-host disease, often fail to restore complete immune system balance. These treatments may suppress beneficial immune responses, leading to increased susceptibility to infections and other complications. A more targeted approach is needed to selectively modulate the immune system and preserve its protective functions.
Solution
AbolerIS Pharma is developing a first-in-class monoclonal antibody, ABIS-45RC, designed to induce immune tolerance and re-establish immune homeostasis in patients with chronic autoimmune and inflammatory conditions. The antibody targets CD45RC, a protein expressed on specific immune cells, aiming to selectively eliminate hyperactive T and B cells responsible for driving autoimmune responses. By targeting CD45RC, the therapeutic approach seeks to preserve beneficial immune responses while suppressing pathological inflammation. Preclinical data suggests that ABIS-45RC can effectively control experimental rheumatoid arthritis by eliminating CD45RChigh T and B cells.
Target Audience
The primary target audience includes patients suffering from chronic autoimmune and inflammatory diseases, such as rheumatoid arthritis, transplant rejection, and graft-versus-host disease, as well as clinicians specializing in rheumatology and immunology.
