About this study

Official title: A Phase I Randomized Single-blind Placebo-controlled Study to Assess the Safety, Tolerability, and Pharmacokinetics of AZD7503 Following Multiple Ascending Dose Administration to Patients With Suspected Non-cirrhotic Non-alcoholic Steatohepatitis (NASH)

The purpose of this study is to measure the safety, tolerability, and PK (measurement of drug activity in the body over time) of AZD7503 injected subcutaneously, and compared to placebo, in participants with suspected NASH, a type of liver disease.

Read the detailed description

This is a Phase I, randomised, single-blind (in which the study centre staff including the Principal Investigator, remain blinded during the clinical conduct of a given cohort) placebo controlled, multiple ascending dose (MAD) study in male and female participants conducted at multiple centres.

Each participant is expected to be in the study for approximately 24 weeks, including a screening period of up to 4 weeks, a 12-week study intervention period, and a follow-up visit at week 18 (10 weeks following the final dose). Participants will be randomly assigned in a 3:1 ratio to receive AZD7503 or placebo. Study intervention will be administered via subcutaneous injection.

What participants receive

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

  • AZD7503Drug

    Each participant is expected to be in the study for approximately 24 weeks, including a screening period of up to 28 days, a 12-week study intervention period, and a follow-up visit at week 18 (10 weeks following the final dose). Participants will be randomly assigned in a 3:1 ratio to receive AZD7503 or placebo. Study intervention will be administered via subcutaneous injection.

What is being measured

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

  1. Number of subjects with adverse events (AEs)

    AEs will be collected at all sites visits per SOA.

    Measured: Up to and including week 19 (from pre-screening to follow-up visit)

  2. Number of subjects with serious adverse events (SAEs)

    SAEs will be reported and collected as they occur.

    Measured: Up to and including week 18 (from pre-screening to final visit).

Secondary outcomes (4)
  1. Maximum observed plasma drug concentration (Cmax)

    PK parameters to be collected per the SOA.

    Measured: Day 1 to Day 127

  2. Area under the concentration-time curve from time 0 to infinity (AUCinf) for plasma PK

    PK parameters to be collected per the SOA.

    Measured: Day 1 to 127

  3. Area under the concentration-time curve over the dosing interval (AUCtau) for plasma PK

    PK parameters to be collected per the SOA.

    Measured: Time frame: Day 1 to 127

  4. Fraction of the dose excreted unchanged into the urine from time t1 to t2 (fe(t1-t2)) for urine PK

    PK parameters to be collected per the SOA.

    Measured: Day 1 and Day 57: Pre-dose and between 0-6 hours, 6-12 hours, 12-24 hours, 24-36 hours and 36-48 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD7503 in people with Steatohepatitis, run by AstraZeneca at 10 sites in 2 countries.

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 12 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: stopped early, as of the sponsor's last update on 20 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, Puerto Rico. 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?

The study was stopped early (reason given: AstraZeneca have decided to not move forward with the development of the compound.). Results are not available in the source record.

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?

Number of subjects with adverse events (AEs) (time frame: Up to and including week 19 (from pre-screening to follow-up visit)). 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 20 Jul 2025.
