About this study

Official title: A Double-Blind, Randomized, Placebo-Controlled, Single Ascending Dose Study to Investigate the Pharmacokinetic Profile of Oral AB680 in Healthy Volunteers

A Double-Blind, Randomized, Placebo-Controlled, Single Ascending Dose Study to Investigate the Pharmacokinetic Profile of Oral AB680 in Healthy Volunteers.

Read the detailed description

The study will evaluate minimum of 2 dose levels of AB680 in 8 participants per cohort. Cohorts will be gender-balanced to the extent possible, and will be randomized 3:1, active vs placebo, respectively.

The participants will be closely observed for the first 48 hours following drug administration to monitor the general tolerability of AB680.

Being tested
AB680, Placebo

What participants receive

Active: Dose EscalationActive comparatorParticipants will receive a single oral dose of AB680 at one of two ascending dose levels. Assignment to receive AB680 will be random.

What is being measured

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

  1. AB680 Peak Plasma Concentration (Cmax)

    Cmax as measured by the Area Under Concentration-Time Curve from Plasma Collection and Analysis.

    Measured: Pre-dose; from First Dose Date to 15 Days After the Last Dose of AB680

  2. AB680 Time of Peak Concentration (Tmax)

    Tmax as measured by the Time to Maximum Concentration-Time Curve from Plasma Collection and Analysis

    Measured: Pre-dose; from First Dose Date to 15 Days After the Last Dose of AB680

  3. Area under the plasma concentration-time curve from time zero to t hours (AUC 0-t) of AB680

    Measured: Pre-dose; from First Dose Date to 15 Days After the Last Dose of AB680

Secondary outcomes (1)
  1. Number of participants with Treatment Emergent Adverse Events (TEAEs)

    Number of participants with TEAEs as assessed by CTCAE v5.0.

    Measured: From First Dose Date to 15 Days After the Last Dose of AB680

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AB680 in people with Healthy Volunteers, run by Arcus Biosciences, Inc. 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 5 inclusion and 4 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 24 May 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 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?

AB680 Peak Plasma Concentration (Cmax) (time frame: Pre-dose; from First Dose Date to 15 Days After the Last Dose of AB680). The study lists 3 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 24 May 2024.
