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.
本公开提供了
重组制造的融合蛋白,其包含与人Fc片段相连的
SARS-CoV-2受体结合域(
SARS-CoV-2-RBD)片段或其类似物,用于2019年新型冠状病毒(COVID-19)。本发明的实施方案包括将融合蛋白注射给从 COVID-19 中康复的患者,作为加强免疫;注射给
抗体幼稚的患者,使其产生针对
SARS-CoV-2 病毒的
抗体,从而使患者成为康复血浆捐献者;注射给已被
SARS-CoV-2 病毒感染并感染 COVID-19 的患者,以限制感染范围并改善病情;以及作为预防性 COVID-19 疫苗。除了使用和制备方法外,还提供了示例性 Fc 融合蛋白和示例性 Fc 融合蛋白的药物制剂。
