Abstract:
The present invention is directed to novel PD-1 targeted heterodimeric Fc fusion proteins comprising an IL-15/IL-15Rα Fc-fusion protein and a PD-1 antibody fragment-Fc fusion protein. In some embodiments, the PD-1 targeted IL-15/Rα-Fc fusion proteins are administered to a patient to treat cancer. In some embodiments, the PD-1 targeted IL-15/Rα-Fc fusion proteins are administered in combination with a PD-1 blockade antibody such as nivolumab and/or pembrolizumab. In some embodiments, the PD-1 targeted IL-15/Rα-Fc fusion proteins do not compete with a PD-1 blockade antibody such as nivolumab and/or pembrolizumab for antigen binding.
