About this study

Official title: CORVax12 - a Phase I Trial of SARS-CoV-2 Spike (S) Protein Plasmid DNA Vaccine (CORVax) +/- pIL-12 (Tavokinogene Telseplasmid) in Healthy Volunteers, With Immunodynamic Biomarker Monitoring of Coordinated Cellular/Humoral Response

This is a Phase 1, open-label study to evaluate the safety profile of CORVax +/- pIL-12, (electroporated SARS-CoV-2 spike (S) protein plasmid DNA vaccine with or without the combination of electroporated IL-12p70 plasmid.

Read the detailed description

This is a Phase 1, open-label study to evaluate the safety profile of CORVax +/- pIL-12, (electroporated SARS-CoV-2 spike (S) protein plasmid DNA vaccine with or without the combination of electroporated IL-12p70 plasmid), given as prime \& boost doses, four weeks apart, in healthy volunteers, divided into age groups of 18-50 versus > 50 years old. IL-12p70 plasmid DNA electroporation (tavokinogene telseplasmid) has been extensively studied in over 209 subjects across 11 trials including later stage human cancer trials with more than 1000 administrations. The IGEA CLINIPORATOR® system is approved for clinical use in Europe, but remains investigational in this study.

One participant will initially be enrolled to each of four cohorts and monitored over a 7-day DLT window:

1A. Age 18-50; CORVax.

  1. B. Age 18-50; CORVax + pIL-12.
  2. A. Age > 50; CORVax.

2B. Age > 50; CORVax + pIL-12.

If after 7 days, no DLT are observed, the cohort may proceed to enroll a second participant. If after monitoring the second participant for 7 days, no DLT are observed, the cohort may proceed to enroll a third participant. If after monitoring the third participant for 7 days, no DLT are observed, the cohort may proceed to enroll six additional participants, for a total of nine participants per cohort using a (1+1+1, +6) design.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CORVax, IL-12 plasmid and Cliniporator in people with SARS-CoV-2, run by Providence Health & Services at 1 site in United States.

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 25 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: stopped early, as of the sponsor's last update on 26 Oct 2024. 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 United States. 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?

Yes. Results are posted in the registry (first posted 26 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Adverse Events Occurring on Day 1 (time frame: Day 1). The study lists 16 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 Oct 2024.
