Abstract: The present invention provides recombinant monoclonal antibodies that bind to the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2 or COVID-19) spike protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to SARS-CoV-2 spike protein. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing SARS-CoV-2 activity, thus providing a means of treating or preventing COVID-19 infection in humans. In some embodiments, the invention provides for a combination of one or more antibodies that bind to the SARS-CoV-2 spike protein for use in treating COVID-19 infection. In certain embodiments, the one or more antibodies bind to distinct non-competing epitopes comprised in the receptor binding domain of the SARS-CoV-2 spike protein.

Abstract: The disclosure provides an immunogenic composition comprising an haptenized Spike protein (S protein) or fragment thereof from a coronavirus and at least one pharmaceutically acceptable carrier, wherein the coronavirus comprising severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Further disclosed are methods of using the haptenized S proteins from coronavirus or immunizing a subject against coronavirus infection.
Abstract: An embodiment provides a method for treatment of the COVID-19 virus, including: preparing an intravenous infusion, wherein the intravenous infusion comprises at least one humanized monoclonal antibody against the SARS-CoV-2 spike protein; introducing the intravenous infusion to a patient; forming a virion antibody complex, wherein the virion antibody comprises the at least one humanized monoclonal antibody against the SARS-CoV-2 spike protein; and monitoring the virion antibody complex from a sample of a body fluid. Other aspects are described and claimed.
Abstract: Compositions and methods are presented for prevention and/or treatment of a coronavirus disease wherein the composition comprises a recombinant entity. The recombinant entity comprises a nucleic acid that encodes a nucleocapsid protein of coronavirus 2 (CoV2); and/or wherein the recombinant entity encodes a spike protein of CoV2.
Abstract: A plant produced vaccine for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is provided where the Spike protein of the virus is expressed in a plant by introducing into a plant a construct comprising a promoter preferentially directing expression to seed of said plant, a nucleic acid encoding the Spike protein and a nucleic acid targeting expression to the endoplasmic reticulum of the plant. The plant expresses the 51 polypeptide at levels of at least 10 mg/kg of seed of said plant. When orally administered to an animal, a protective response is observed including a serum antibody response.

Abstract: The present disclosure provides a method and a platform for enhancing detection activity of an interaction between a spike protein receptor binding domain of coronavirus from a specimen and a human angiotensin-converting enzyme II. The method and the platform of the present disclosure use a cleavable luciferase as a report test for the combination of the spike protein receptor binding domain of coronavirus (such as novel coronavirus) and angiotensin-converting enzyme II. Screening is carried out at the cellular level. The strength of the drug's influence on the interaction between the two molecules can be judged by the strength of the luminescence signal. The detection time can be completed within 20 minutes.
Abstract: Disclosed is producing recombinant SARS-CoV-2 spike protein in a pre-fusion state, using furin knock out or knockdown mammalian cells (such as HEK293, CHO or other mammalian cells). The pre-fusion state SARS-CoV-2 spike protein can be used as an antigen to generate antibodies/binding molecules for use in SARS-CoV-2 detection assays or in diagnosis of active or prior infection with SARS-CoV-2; as a therapeutic to interfere with SARS-CoV-2 cellular binding; to generate antibodies/binding molecules to SARS-CoV-2 for use in therapy; or, as a vaccine for generating immunity to SARS-CoV-2; or for prophylactic or therapeutic use against related coronaviruses.
