  • Patent number: 11512122
    Abstract: Provided herein are dimeric IL-7-Fc fusion proteins that include Fc domains and one or more IL-7s. Also provided herein are variant IL-7s with modifications to reduce heterogeneity and/or reduced affinity/potency. Such variant IL-7s are useful, for example, in the subject dimeric IL-7-Fc fusion proteins. The dimeric IL-7-Fc fusion proteins can be used for applications where increased IL-7 activity is useful, for example, for increasing the proliferation of lymphocyte populations in mounting an anti-tumor response in a subject in need thereof.

  • Patent number: 11377477
    Abstract: The present invention is directed to novel PD-1 targeted heterodimeric Fc fusion proteins comprising an IL-15/IL-15R? Fc-fusion protein and a PD-1 antibody fragment-Fc fusion protein. In some embodiments, the PD-1 targeted IL-15/R?-Fc fusion proteins are administered to a patient to treat cancer. In some embodiments, the PD-1 targeted IL-15/R?-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?-Fc fusion proteins do not compete with a PD-1 blockade antibody such as nivolumab and/or pembrolizumab for antigen binding.
