CD40-CD40L interaction is an attractive target for blocking T-cell–mediated B-cell–driven autoimmunity and prevention of solid organ transplant rejection. External proof-of-concept for inhibition of this pathway has been previously established in patients with a broad range of autoimmune diseases, including rheumatoid arthritis, Sjögren’s syndrome, Graves’ disease, systemic lupus erythematosus and solid organ transplant.
We are enrolling healthy subjects in a single-ascending-dose Phase 1 clinical trial. The first-in-human trial will provide safety data and pharmacokinetics as well as receptor occupancy and T-cell Dependent Antibody Responses. Top-line data are expected in the second half of 2020.
