OUTRACE Studies Resource Library
This website provides information and resources on the OUTRACE studies, which are evaluating the T cell engager, CLN-978. CLN-978 is an investigational therapeutic approach that has the potential to offer a convenient, off-the-shelf, subcutaneously delivered therapeutic option for people living with autoimmune diseases.

ABOUT CLN-978
An overactive immune response, driven by B cells and/or T cells, may lead to the development of autoimmune diseases.
CLN-978 is a subcutaneously* administered CD19-directed T cell engager. T cell engagers are an emerging therapeutic approach in autoimmune diseases, with the potential to modulate immune responses in ways that may enable durable disease control and advance current treatment strategies:
- T cell engagers can harness the immune system in autoimmune diseases to eliminate disease-causing cells.
- T cell engagers like CLN-978 are bispecific antibodies designed to guide the immune system’s T cells to find and eliminate harmful cells, such as autoreactive cells that carry specific markers on their surface.
- CLN-978 works by linking T cells and B cells together by binding to CD3 on T cells and CD19 on B cells.
- Once the T cell is linked with the B cell, the T cell then destroys the targeted harmful cell.
We are currently evaluating CLN-978 in people living with Systemic lupus erythematosus, Rheumatoid arthritis, and Sjögren’s disease. CLN-978 is investigational and has not been approved by any health authority.
