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