What is being measured

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

  1. To determine the incidence and frequency of adverse events as a measure of safety and tolerability of ARC-520

    The incidence and frequency of adverse events (AEs), serious adverse events (SAEs), related AEs, related SAEs, and AEs leading to withdrawal, dose modification, or treatment discontinuation will be summarized by dose and treatment group.

    Measured: One month

Secondary outcomes (1)
  1. To evaluate the pharmacokinetics of ARC-520 at different dose concentrations

    Plasma concentrations following a single dose of ARC-520 at different dose levels will be used to calculate the following ARC-520 pharmacokinetic parameters: Cmax, tmax, AUC0-24, AUCinf, and t1/2. Descriptive statistics of pharmacokinetic parameters will include mean, standard deviation, and coefficient of variation.

    Measured: 2 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ARC-520 in people with Healthy, run by Arrowhead Pharmaceuticals at 1 site in Australia.

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 2 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: 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 Australia. 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?

To determine the incidence and frequency of adverse events as a measure of safety and tolerability of ARC-520 (time frame: One month). 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.
