The present disclosure provides recombinantly manufactured fusion proteins comprising a Programmed Death-Ligand 1 (PD-L1) protein fragment or an analog thereof linked to a canine Fc fragment. Embodiments include the administration of the fusion proteins to patients as a treatment for cancers, tumors or other diseases associated with expression of the PD-L1 protein in dogs. Exemplary Fc fusion proteins and pharmaceutical formulations of exemplary Fc fusion proteins are provided, in addition to methods of use and preparation.

PD-L1 analog fusion proteins for antigen specific immunotherapy and methods of use

The present disclosure provides recombinantly manufactured fusion proteins comprising a SARS-CoV-2 Receptor Binding Domain (SARS-CoV-2-RBD) fragment or an analog thereof linked to a human Fc fragment for use in relation to the 2019 Novel Coronavirus (COVID-19). Embodiments include the administration of the fusion proteins to patients that have recovered from COVID-19 as a booster vaccination, to antibody naïve patients to produce antibodies to the SARS-CoV-2 virus to enable the patients to become convalescent plasma donors, to patients who have been infected by the SARS-CoV-2 virus and have contracted COVID-19 in order to limit the scope of the infection and ameliorate the disease, and as a prophylactic COVID-19 vaccine. Exemplary Fc fusion proteins and pharmaceutical formulations of exemplary Fc fusion proteins are provided, in addition to methods of use and preparation.

Antigen specific immunotherapy for COVID-19 fusion proteins and methods of use

The present disclosure relates to compositions of insulin-Fc fusion proteins and their use to treat feline diabetes.

Ultra-long acting insulin-Fc fusion protein and methods of use

The present disclosure relates to compositions of insulin-Fc fusion proteins and their use to treat diabetes.

Ultra-long acting insulin-Fc fusion protein

The present disclosure provides recombinantly manufactured ultra-long acting insulin-Fc fusion proteins for use in treating canine diabetes. The insulin-Fc fusion proteins comprise an insulin polypeptide linked via a peptide linker to an Fc-fragment of canine origin. Based on the results obtained, creating a treatment that is amenable to low cost manufacturing, exhibits sufficient in vivo bioactivity, displays extended duration of bioactivity, does not induce anti-drug antibodies, and substantially retains is potency over multiple administrations, requires a non-obvious combination of insulin polypeptide, peptide linkers, and species-specific Fc fragment, in addition to selective mutations on one or more of these components. Exemplary ultra-long acting insulin-Fc fusion proteins, polynucleotides encoding these insulin-Fc fusion proteins, and pharmaceutical formulations of exemplary insulin-Fc fusion proteins are provided, in addition to methods of use and preparation.

Ultra-long acting insulin-Fc fusion proteins and methods of use

The present disclosure provides recombinantly manufactured ultra-long acting insulin-Fc fusion proteins for use in treating canine and feline diabetes.
