简要总结
This study will assess the safety and immunogenicity of AG0302-COVID19 in healthy adult volunteers.
详细描述
This is a Phase 1/2, single-center, randomized, open-label, non-controlled trial. Approximately 30 healthy volunteers, male or female, aged 20-65, will be randomized to one of the following three groups.
Group A: Vaccination twice at 2-week intervals (n = 10) Group B: Vaccination twice at 4-week intervals (n = 10) Group C: Vaccination 3 times at 2-week intervals (n = 10)

- •Subjects who are negative for SARS-CoV-2 by PCR test
- •Subjects who are negative for both SARS-CoV-2 IgM antibody and SARS-CoV-2 IgG antibody by antibody test
排除标准
- •Subjects with symptoms of suspected COVID-19 infection (respiratory symptoms, headache, malaise, olfactory disorders, taste disorders, etc.)
- •Subjects with a history of COVID-19 (hearing from subjects)
- •Subjects who have participated in unapproved vaccine clinical trials

- •Females who wish to become pregnant from the date of study registration to 12 weeks after the first inoculation of the investigational drug, and pregnant females who are breast-feeding. In addition, females who may become pregnant and their male sexual partners should use appropriate contraceptives (pill), condoms, vasectomy, tubal ligation, diaphragm, intrauterine devices, spermicides, intrauterine hormone-releasing system, etc. from the study entry date until 12 weeks after the first vaccination
- •Subjects who have participated in clinical trials of other unapproved drugs and received the investigational drug within 4 weeks before the start of this clinical trial (starting from vaccination day)
- •Subjects who have been received a live vaccine, inactivated vaccine, or toxoid within 4 weeks before the start of this clinical trial (starting from vaccination day)
- •Subjects who have been administered with drugs that affect the immune system (excluding external preparations) such as immunomodulators (DMARDs, etc.), immunosuppressants, biologics, etc. within 4 weeks before vaccination
- •Subjects who received blood transfusion or gamma globulin therapy within 12 week before vaccination, or high-dose gamma globulin therapy (200 mg/kg or more) within 24 weeks before vaccination
- •Subjects who have a history of overseas travel within 4 weeks before the start of the clinical trial (starting from vaccination day)
- •Subjects who are unable to comply with the clinical trial protocol and follow up (for mental, family, social or geographical reasons)
- •Subjects who are judged to be ineligible for this clinical trial by the investigator
