Interventions

The novel coronavirus broad-spectrum neutralizing antibody SA55 nasal spray (SA55 nasal spray) is provided by Beijing Kexing Zhongwei Biotechnology Co., Ltd. The main component of this product is the novel coronavirus broad-spectrum neutralizing antibody, which is a colorless to pale yellow solution. Each milliliter contains 5mg of broad-spectrum neutralizing antibody against novel coronavirus. Excipients include histidine hydrochloride, arginine hydrochloride, histidine, sucrose, polysorbate 80 (II), hydroxypropyl cellulose, glycerol, and benzalkonium chloride (concentration 0.005%). 20 sprays per bottle, approximately 100 sprays per bottle μ L. Containing 0.5 mg of broad-spectrum neutralizing antibody against novel coronavirus.

  • Previous history of sinus and septum surgery or radiotherapy;
  • Patients with nasal diseases that may affect the deposition/absorption of drugs in the nose (such as narrowing of the nasal vestibule, severe deviation, perforation, ulcer of the nasal septum, thickening, pallor, edema, erosion of the nasal mucosa, hypertrophy and atrophy of the nasal wings, accumulation of fluid and pus in the nasal cavity, and space occupying or vegetation in the nasal cavity);
  • Abnormal examination of the oropharynx has clinical significance, such as congestion, thickening, ulcers, hyperplasia or nodules, new organisms or foreign bodies of the throat mucosa;
  • The following symptoms or diseases with clinical significance: a) a history of long-term nasal congestion, runny nose, headache, nosebleed, and other symptoms; b) Asthma, chronic respiratory diseases, etc; c) History of allergic rhinitis, chronic rhinitis, and sinusitis; d) History or signs of nasal, pharyngeal, and upper respiratory diseases that other researchers believe may affect the interpretation of the research process and/or local adverse events;
  • Suffering from severe neurological disorders (epilepsy, seizures or convulsions) or mental illness, with a family history of mental illness, and neurological and psychiatric problems associated with various organic disorders;
  • Abnormal coagulation function (such as coagulation factor deficiency, coagulation disorders, platelet abnormalities) or obvious bruising or coagulation disorders diagnosed by a doctor;
  • Other uncontrolled chronic or severe disease history, including but not limited to cardiovascular disease, hematological system disease, liver and kidney disease, digestive system disease, respiratory system disease, malignant tumor, history of major organ transplantation, HIV/HBV/HCV/syphilis infection, or any other disease or physiological condition that the researcher believes can interfere with the test results;
  • Planned pregnancy within 3 months, already pregnant (including positive pregnancy test), or breastfeeding;
  • Received any SARS-CoV-2 neutralizing antibody injection that has been marketed or under research within 180 days prior to screening, or participated in clinical trials of other drugs or medical devices within 90 days prior to screening;
