    Measurement of PK parameters: Area under the concentration time curve (AUC)

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

  8. Pharmacokinetics of AZD9592: Maximum plasma concentration of the study drug (C-max)

    Measurement of PK parameters: Maximum observed plasma concentration of the study drug (C-max)

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

  9. Pharmacokinetics of AZD9592: Time to maximum plasma concentration of the study drug (T-max)

    Measurement of PK parameters: Time to maximum observed plasma concentration of the study drug (T-max)

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

  10. Pharmacokinetics of AZD9592: Clearance

    Measurement of PK parameters: the volume of plasma from which the study drug is completely removed per unit time (Clearance)

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

  11. Pharmacokinetics of AZD9592: Half-life

    Measurement of PK parameters: Terminal elimination half-life (t 1/2)

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

  12. Immunogenicity of AZD9592: Anti-Drug Antibodies (ADA)

    Evaluating the number and percentage of patients who develop Anti-drug antibody (ADA) during treatment

    Measured: From date of first dose of AZD9592 up until 30 days post last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD9592, Osimertinib and 5-Fluorouracil (5-FU) in people with Advanced Solid Tumours and Carcinoma Non-small Cell Lung, run by AstraZeneca at 46 sites in 11 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 11 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 25 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 46 sites in United States, China, Italy, South Korea, Taiwan and 6 more countries. 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?

This study is still under way. Results are not available in the source record yet.

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?

Incidence of Adverse Events (AEs) (time frame: From time of Informed Consent to 30 days post last dose of AZD9592). The study lists 5 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 25 Sep 2026.
