About this study

Official title: Adaptive Phase I Clinical Trial of Preventive Vaccine Consisting of Autologous Dendritic Cells Previously Incubated With S-protein From SARS-CoV-2, in Subjects Negative for COVID-19 Infection and Anti-SARS-CoV-2 Antibodies

This is an adaptive Phase I trial of a vaccine consisting of autologous dendritic cells previously loaded ex vivo with SARS-CoV-2 spike protein, with or without GM-CSF, to prevent COVID-19 in adults.

Read the detailed description

Subjects eligible for treatment will be those who at baseline, are not actively infected with SARS-CoV-2, have no evidence of prior infection with SARSCoV- 2 based on serologic testing, and give informed consent for a vaccination with AV-COVID-19. The patient population will include the elderly and others at higher risk for poor outcomes after COVID-19 infection. For this reason, individuals will not be excluded solely on the basis of age, body mass index, history of hypertension, diabetes, cancer, or autoimmune disease.

After enrolling for screening, subjects will undergo a nasal swab test to exclude active COVID-19 infection and a rapid test for anti-coronavirus antibodies to exclude pre-existing anti-SARS-CoV-2 antibodies. 50 mL of blood will be collected, from which peripheral blood monocytes will be isolated and differentiated into DC before incubation with SARS-CoV-2 S-protein, during which time the protein is digested into 9 to 25 amino acid peptide sequences presented on the dendrites of DC in conjunction with histocompatibility class I and class II molecules. Safety and quality testing will be performed on a small quantity of the batch, and the remaining AV-COVID-19 will be cryopreserved for shipping to the treatment site.

Once the Study Drug is ready, if eligible, the subject will be seen at Study Week-0 for treatment. Prior to injection of the Study Drug, a nasal swab test will be collected to confirm that they are still negative for COVID-19, and blood will be drawn to determine baseline levels of anti-SARS-CoV-2 antibodies. At the treatment site, the product will be thawed and admixed with saline or (saline with GM-CSF), and within 5 hours of thawing, will be injected SC via a 25- gauge needle

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AV-COVID-19 in people with COVID-19, run by Indonesia-MoH at 1 site in Indonesia.

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 3 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 29 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Indonesia. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact Muhammad Karyana, Dr., MPH (+62 21 4261088, mkaryana@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of solicited local and systemic reactogenicity adverse events (AEs) (time frame: until follow up day 7). The study lists 7 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 29 Dec 2020.
