Safety and Immunogenicity Study of COVID-19 Protein Subunit Recombinant Vaccine Adjuvanted With Alum+CpG 1018

Phase 1
Completed
Conditions
COVID-19
Interventions
Biological: SARS-CoV-2 inactivated vaccine
Biological: SARS-CoV-2 protein subunit recombinant vaccine
Registration Number
NCT05228613
Lead Sponsor
PT Bio Farma
Brief Summary

The study is an observer-blind, randomized, controlled prospective intervention study of Phase I. The primary objective is to evaluate the safety and immunogenicity of the SARS-CoV-2 protein subunit recombinant vaccine adjuvanted with Alum+CpG1018

Detailed Description

This trial is observer blinded, comparative, randomized, phase I study. Approximately 175 subjects will be recruited (18 years and above).

The investigational product is 0.5 ml in two dose-regimen (for all subjects) with 28 days apart between doses, compare to an active control (inactivated SARS-CoV-2 vaccine). There will be 4 formula of investigational product used with different concentration of Receptor Binding Domain (RBD) antigen and adjuvant CpG 1018.

  9. History of uncontrolled coagulopathy or blood disorders contraindicating intramuscular injection.
  10. Patients with serious chronic diseases (serious cardiovascular diseases, uncontrolled hypertension and diabetes, liver and kidney diseases, malignant tumors, etc) which according to the investigator might interfere with the assessment of the trial objectives.
  11. Subjects who have any history of confirmed or suspected immunosuppressive or immunodeficient state, or received in the previous 4 weeks a treatment likely to alter the immune response (intravenous immunoglobulins, blood-derived products or long-term corticosteroid therapy (> 2 weeks)).
  12. Subjects who have history of uncontrolled epilepsy or other progressive neurological disorders, such as Guillain-Barre Syndrome.
  13. Subjects receive any vaccination (other than COVID-19 vaccine) within 1 month before and after IP immunization.
  14. Subjects plan to move from the study area before the end of study period.
