Safety and Immunogenicity Study of SARS-CoV-2 Nanoparticle Vaccine (GBP510) Adjuvanted With Aluminum Hydroxide (COVID-19)

COVID-19 (Healthy Volunteers) Clinical Trial

Official title: A 2-Stage, Phase I/II, Placebo-controlled, Randomized, Observer-blinded, Dose-finding Study to Assess the Safety, Reactogenicity, and Immunogenicity of a SARS-CoV-2 Recombinant Protein Nanoparticle Vaccine (GBP510) Adjuvanted With Aluminum Hydroxide in Healthy Younger and Older Adults

Status Completed

Clinical Trial Summary

This is a first-in-human, Phase I/II, randomized, placebo-controlled, observer-blinded, age-escalating study to assess the safety, reactogenicity and immunogenicity of a SK SARS-CoV-2 recombinant protein nanoparticle vaccine (GBP510) adjuvanted with Alum in healthy younger and older adults.

Clinical Trial Description

The purpose of this study is to assess the safety, reactogenicity and immunogenicity of the candidate vaccine administered twice with 28-day interval in healthy adults including older adults.

A total of 260 healthy younger and older adults will be enrolled to receive 2 doses of either one GBP510 formulation (Test group 1 or 2) or placebo saline (Placebo group).

This study will consist of 2 stages, and a stepwise approach will be adopted as a safety precaution. Approximately 60 healthy adults aged 19 to 55 years will be enrolled and vaccinated first in Stage 1, and blinded safety data collected through 7 days after the last study vaccination will be reviewed by the sponsor, and then by the independent Data Safety Monitoring Board (DSMB) in an unblinded manner. Advancement to Stage 2 for further enrollment of 200 healthy younger and older adults aged 19 to 85 years will be determined if an acceptable safety profile is confirmed based on the sponsor and DSMB review. DSMB will recommend whether to proceed to the next stage or not, and DSMB may suggest discontinuation of the study or adjustment of dose and dosing regimen based on the safety review. ;
