Trial summary

Following oncolytic virus (OV) administration, the host immune response is initiated immediately and evolves dynamically. However, in clinical OV therapy, it is virtually impossible to capture these immune events in real time. Read more about this study

About this study

Official title: High-Resolution Immune Dynamics Following OTS-412 Oncolytic Vaccinia Virus Administration in a Healthy Volunteer(Self-experiment)

Following oncolytic virus (OV) administration, the host immune response is initiated immediately and evolves dynamically. However, in clinical OV therapy, it is virtually impossible to capture these immune events in real time. To address this gap, the principal investigator conducted a high-resolution immune monitoring study in a healthy volunteer.

Being tested
OTS-412

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing OTS-412 in people with Healthy Volunteer, run by Bionoxx Inc. at 1 site in South Korea.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 26 Dec 2025. 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 South Korea. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes in ANC(absolute neutrophil count) over time (time frame: 4 hour, 8 hour, 20 hour, 24 hour, Day 2, Day 5, Day 8, Day 16). The study lists 2 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 Dec 2025.
