About this study

Official title: A Phase I, Open-label Study to Evaluate the Ability of UB-612 Vaccine to Boost Immunity of Heterologous COVID-19 Vaccines

This is a study to evaluate the ability of UB-612 vaccine to boost immunity of subjects who previously received two doses of AstraZeneca COVID-19 vaccine (ChAdOx1-S) with an 8-16 week interval between first and second doses.

Read the detailed description

This is a phase I, open-label clinical study to evaluate the ability of UB-612 vaccine to boost immunity of subjects who previously received two doses of AstraZeneca COVID-19 vaccine (ChAdOx1-S) with an 8-16 week interval between first and second doses.

This study will enroll approximately 30 subjects aged 20 to 55 years. The previous COVID-19 vaccine series will have been completed at least six months before study enrollment. Both sexes should be evenly distributed in subjects.

Subjects will be enrolled to receive one dose of 100 μg UB-612 vaccine at Day 1. The subjects will come to the clinics at Visit 1 (screening, Day -28 to -1), Visit 2 (Day 1, vaccination), Visit 3 (Day 15, 14 days after vaccination), Visit 4 (Day 29, 28 days after vaccination), Visit 5 (Day 169, 6 months after vaccination) and will receive phone calls at 7 days after vaccination for safety check.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing UB-612 in people with COVID-19, run by United Biomedical Inc., Asia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 26 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and tolerability (time frame: within 7 days after vaccination). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2022.
