Drug Details

Belatacept is a CTLA4-Ig fusion protein that binds CD80 and CD86 thereby blocking CD28 co-stimulatory signals. Belatacept has been extensively studied in kidney transplantation. In a long-term study, patients treated with Belatacept had better survival than those treated with Cyclosporine. Importantly, Belatacept-treated patients were significantly less likely to develop donor-specific HLA antibodies than Cyclosporine-treated patients. Nonetheless, Belatacept has not been formally evaluated after lung transplantation. The investigators hypothesize that Belatacept-based immunosuppression would result in a lower incidence of donor-specific HLA antibodies and that this would result in better chronic lung allograft dysfunction-free survival after transplantation. 

Study Purpose

This is a pilot randomized controlled trial examining the feasibility of conducting a large scale randomized controlled trial of belatacept-based immunosuppression in lung transplantation. This pilot study will enroll 40 lung transplant recipients and randomize them to belatacept-based immunosuppression or standard of care. The primary endpoint of the study is the development of donor-specific HLA antibodies after transplantation. All study participants will be followed for a minimum of 12 months after transplantation.
