About this study

Official title: A Study to Determine the Rel Bio of AZD9833 Formulations, Food Effects and the Absolute Bioavailability of AZD9833 Following Co-Administration of an Oral Tablet Formulation With a Radiolabelled Intravenous Microdose of [14C]AZD9833

AstraZeneca AB is developing the test medicine, AZD9833, for the potential treatment of oestrogen receptor (ER) positive breast cancer. ER-positive breast cancer is where the cancer cells grow in response to the hormone oestrogen.

The study will try to identify and compare how much of the test medicine formulations (recipes) are taken up into the blood when given as a tablet, a solution and as an injection directly into the vein. The dose given directly into the vein will be radiolabelled, meaning that it contains a radioactive component in order to track where the drug is in the body.

Read more

This study will also look at the effect of food when taking the test medicine in the form of the tablet. The test medicine safety and tolerability will also be assessed.

This is a one-part study involving up to 32 healthy post-menopausal female volunteers aged 50 to 70. Volunteers will be randomly assigned to a group of up to 8, two groups will partake in four study periods and two groups will partake in three study periods. Volunteers will be admitted to the clinical unit on the day before dosing (Day -1) for each study period. On Day 1 of each study period, volunteers will receive either a single oral dose (tablet or solution) of AZD9833 or a single oral dose (tablet) of AZD9833 co-administered with a single radiolabelled IV dose of [14C]AZD9833, in either the fed or fasted state. There will be a minimum 7 day washout between periods.

Volunteers will remain resident until 72 hours post dose (Day 4) of each study period. A follow-up phone call will take place 5 to 7 days post-final dose to ensure the ongoing wellbeing of the volunteers.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C]AZD9833 Solution for Infusion, (NMT 22.8 kBq/5mL), AZD9833 film-coated tablet A Dose 1 and AZD9833 Oral Solution in people with Healthy Volunteers, run by AstraZeneca at 1 site in United Kingdom.

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 32 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 20 Jan 2021. 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 United Kingdom. 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 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?

Relative bioavailability of AZD9833 based on Area under the curve from time 0 to the time of last measurable concentration (AUC0-t) (time frame: Collection of plasma samples from pre-dose to 72 hours post-dose). 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?

On the ClinicalTrials.gov record for NCT04546347.

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 Jan 2021; AzTrials last refreshed its copy on 27 Oct 2026.
