About this study

Official title: Exploratory, Single-dose, Phase I Clinical Trial to Evaluate the Safety, Tolerability and Pharmacokinetics of DNP007 in Healthy Subjects

This clinical trial evaluated the safety, tolerability, pharmacokinetic properties, and immunogenicity of DNP007 when administered as a single dose. Since this is a phase 1 study for exploratory evaluation, to the extent that it meets the study objectives, In order to proceed with the minimum number of subjects, a total of 12 people, 3 for each dose group, was planned as the target number.

Read the detailed description

For volunteers only, screening tests such as questionnaires, physical examinations, and clinical laboratory tests will be conducted within 4 weeks (-28d to -1d) from the date of clinical trial conduct to select test subjects deemed suitable for this clinical trial. Subjects determined to be suitable for this clinical trial are admitted to the Seoul National University Hospital Clinical Trial Center in the afternoon one day (-1d) before the first administration of the investigational drug and must fast for at least 10 hours. In the morning of Day 1, test subjects receive intravenous administration of the clinical trial drug for 30 minutes. Pharmacokinetics, immunogenicity and safety evaluations are conducted according to the planned schedule. Test subjects are hospitalized at the clinical trial center for 4 days (discharged on the 4th day), and after administration of the investigational drug, on 8d, 11d, 15d, 22d (±1d), and 29d (±2d), for pharmacokinetics, immunogenicity, and safety evaluation. Visit the clinical trial center. It proceeds sequentially starting from the lowest dose group, and whether to proceed to the next dose is decided based on the tolerability and safety results up to 15 days of the previous dose.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DNP007Drug

    Also called MD3, Anti-ICAM1

    DNP007 is a therapeutic agent that can replace calcineurin inhibitor (CNI), which is a representative factor that can be used as an adhesive for extrahepatic long-term survival patches such as after liver transplantation in patients with liver disease and hepatocellular carcinoma, adult metabolic status, neoplasms, etc. , an anti-ICAM-1 mouse monoclonal minority, is a humanized Fab region that humanizes MD-3 and the Fc region of human IgG1, separated by translational engineering.

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 18 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 18 Jun 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 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?

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 Dongkyu Han, Ph.D. (+82-10-2515-9333, gksehdrb33@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Plasma Concentration (Cmax) (time frame: 0minute (before single intravenous administration), 10, 20, 30 minutes after administration (at completion of infusion), 1, 2, 4, 8, 12, 24, 48, 72, 168hours (Day8), 240hours (Day11), 336hours (Day15), 504hours (Day22±Day1), 672hours (Day29±Day2)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06400771, which also lists 2 linked publications.

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 18 Jun 2024.
