Abstract: The present disclosure relates to antibodies, in particular monoclonal antibodies of murine, chimeric, and humanized origin, that specifically bind to the human TROP2 protein, and to the amino acid and nucleotide sequences encoding these antibodies. The disclosure also discloses the use of these antibodies as a diagnostic reagent or a drug in the diagnostic and/or therapeutic management of malignancies or any lesion related to the overexpression of the receptor.

Abstract: A method for treating cancer in a subject comprising, administering to the subject a bispecific antibody having a binding specificity to EGFR and HER3 and a therapeutic agent, wherein the therapeutic agent comprises a tyrosine kinase inhibitor (TKI), an alkylating agent, an anti-metabolite, an anti-microtubule agent, a cytotoxic antibiotic, a topoisomerase inhibitor, a chemoprotectant, or a combination thereof.

Abstract: A method of preventing, reducing a risk of, or treating a virus infection, or preventing or treating a symptom caused by the virus in a subject, said method comprising administering to said subject an effective amount of a fusion protein, wherein the fusion protein comprises a variant angiotensin converting enzyme 2 (ACE2) domain covalently fused to a Fc domain. The variant ACE2 domain comprises a N-terminal deletion, a C-terminal deletion, or both, relative to a full-length wildtype ACE2 having a SEQ ID NO. 1, and the variant ACE2 domain has ACE2 activity. The virus may be SARS-CoV, SARS-CoV-2, or MERS-CoV. The symptom comprises Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), Acute Respiratory Distress Syndrome (ARDS), Pulmonary Arterial Hypertension (PAH), or Coronavirus Disease 2019 (COVID-19).
