About this study

Official title: A Randomized, Single-center, Double-blind, Placebo Controlled, First-in-human Trial With Single Ascending Intravenous Doses to Determine Safety, Tolerability and Pharmacokinetics of AON-D21 in Healthy Male Subjects

The main purpose of this study is to evaluate safety, tolerability, pharmacokinetics and pharmacodynamic parameters after single ascending intravenous doses of AON-D21 in healthy male subjects.

Read the detailed description

This study will potentially include 5 sequential cohorts with 8 subjects per cohort, then 40 enrolled subjects in total. Within each dose group 6 subjects will be randomized to receive AON-D21 and 2 subjects will be randomly assigned to placebo.

Conditions
Healthy
Being tested
Intravenous AON-D21, Intravenous placebo

What participants receive

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

  • Intravenous AON-D21Drug

    Also called AON-D21

    AON-D21 is a Pegylated L-configured aptamer that binds and thereby neutralizes the complement component C5a from activating both C5a receptors.

  • Intravenous placeboDrug

    Also called Placebo

    Isotonic glucose solution identical in appearance to AON-D21.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Safety Endpoint - Overall number of participants with treatment-emergent adverse events (TEAEs) per dosing cohort as assessed by CTCAE.

    To determine the overall safety and tolerability of AON-D21 by analyzing number of participants with treatment-related adverse events as assessed by CTCAE. Nature, occurrence, and severity of treatment-emergent adverse events.

    Measured: 14 days.

  2. Primary Safety Endpoint - Per Dosing Cohort number of participants with treatment-emergent adverse events as assessed by CTCAE.

    Overall number of participants with treatment related treatment-emergent adverse events (TEAEs) as assessed by CTCAE per dosing cohort.

    Measured: 14 days

Secondary outcomes (10)
  1. Pharmacokinetics of AON-D21.

    To determine the area under the concentration (AUC)-time curve from 0 to 48 h (AUC0-48).

    Measured: 14 days.

  2. Pharmacokinetics of AON-D21.

    To determine the area under the concentration (AUC)-time curve from 0 to 72 h (AUC0-72).

    Measured: 14 days.

  3. Pharmacokinetics of AON-D21.

    To determine the area under the concentration (AUC)-time curve from 0 to infinity (AUC0-inf).

    Measured: 14 days.

  4. Pharmacokinetics of AON-D21.

    To determine the maximum concentration (Cmax).

    Measured: 14 days.

  5. Pharmacokinetics of AON-D21.

    To determine the time of maximum concentration (Tmax).

    Measured: 14 days.

  6. Pharmacokinetics of AON-D21.

    To determine the half-life (t1/2).

    Measured: 14 days.

  7. Pharmacokinetics of AON-D21.

    To determine the plasma clearance (CL) calculated as Dose/AUC0-inf.

    Measured: 14 days.

  8. Pharmacokinetics of AON-D21.

    To determine the volume of distribution (Vz).

    Measured: 14 days.

  9. Pharmacokinetics of AON-D21.

    To determine the amount of AON-D21 excreted (Ae) in urine.

    Measured: 14 days.

  10. Pharmacokinetics of AON-D21.

    To determine the renal clearance (CLR) of AON-D21.

    Measured: 14 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Intravenous AON-D21 in people with Healthy, run by Aptarion Biotech AG at 1 site in Germany.

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 6 inclusion and 16 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 12 Jan 2022. 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 Germany. 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. Some participants in this study may receive a placebo. 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 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?

Primary Safety Endpoint - Overall number of participants with treatment-emergent adverse events (TEAEs) per dosing cohort as assessed by CTCAE. (time frame: 14 days.). 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 12 Jan 2022.
