NCT05369754

Brief Summary

This is phase Ia study to research YBSW015 injection which is a monomolecular bispecific antibody. The Primary objective is to evaluate the safety and tolerability of YBSW015 injection after a single intravenous injection at different doses in healthy subjects. The Secondary objective is to evaluate the pharmacokinetic characteristics and immunogenicity of different doses of YBSW015 injection after a single intravenous injection in healthy subjects. This study is a single-center, randomized, double-blind, placebo-controlled, single-dose escalation clinical trial.

  • Has completed COVID-19 vaccination and the last dose more than 6 weeks prior to randomization
  • Subject who are normal in the physical examination, vital signs, laboratory tests and other auxiliary examinations (chest radiograph, abdominal ultrasound scan, 12-lead ECG, etc.), or abnormal without clinical significance as judged by the investigator;
  • Subject who has a negative result in the urine human chorionic gonadotropin test in screening period, and a negative result in the blood human chorionic gonadotropin test in baseline period;
  • Subjects (including their partners) who do not have a pregnancy plan and are willing to adopt effective contraception measures from signing the informed consent to 6 months after administration of the investigational drug;
  • Subjects who has understood the trial feature, significance, possible benefits, possible inconveniences and potential risks and discomforts in detail, and are willing to participate in this clinical trial and are able to communicate well with the investigator and follow the requirements of the entire study, and has signed the written informed consent form prior to the trial.

You may not qualify if:

  • The positive results are obtained in SARS-CoV-2 nucleic acid test using nasal swabs prior to screening and randomization (results within 7 days prior to randomization);
  • Has recent SARS-CoV-2 infection that resolved within 6 weeks prior to randomization;
  • Those who have received any SARS-CoV-2 immunoglobulin, plasma from COVID-19 survivors in recovery period(within 15 weeks);
  • Those who have used therapeutic biologics within 12 weeks before screening, or those who are in drug elimination period currently (within 5 half-lives), whichever is longer;
  • Those who have participated in clinical study of other intervention investigational products within 12 weeks prior to screening, or those who are in drug elimination period currently (within 5 half-lives), whichever is longer;
  • Those who have been vaccinated against pathogens other than SARS CoV-2 within 6 weeks prior to screening, or plan to be vaccinated against pathogens other than SARS CoV-2 during the study or within 6 weeks after the study;
  • Those who have taken herbal medicines, dietary supplements (excluding vitamin, mineral and trace element supplements), or any prescription or non-prescription drugs within 14 days (inclusive) prior to screening;
  • Those who have had major surgery history within 8 weeks (including 8 weeks) before screening, or plan to perform surgeries during the study, and those who are exposed to unacceptable risks brought by such surgery at the discretion of the sponsor and the investigator;
