About this study

Official title: An Open-Label, Fixed Sequence Study in Healthy Post Menopausal Female Subjects to Assess the Pharmacokinetics of Camizestrant (AZD9833) When Administered Alone and in Combination With Itraconazole

This study will be conducted in healthy post-menopausal female subjects to assess the pharmacokinetics (PK) of Camizestrant (AZD9833) when administered alone and in combination with Itraconazole.

Read the detailed description

This open-label, fixed sequence study will comprise of:

  • A screening period of 28 days;
  • A fixed sequence of three treatment period:

Treatment Period 1: Camizestrant only, Treatment Period 2: Itraconazole only, Treatment Period 3: Camizestrant and Itraconazole in combination.

  • A Follow-up Visit at 7 to 14 days after the last Camizestrant PK sample in Period 3.

There will be a washout period of 7 to 10 days between Period 1 and Period 2. Each subject will be involved in the study for approximately 8 or 9 weeks.

Being tested
Camizestrant, Itraconazole
Keywords
Pharmacokinetics, Breast Cancer, Selective Estrogen Receptor Degrader (SERD), ER-Positive, HER2- Negative Breast Cancer

What participants receive

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

  • CamizestrantDrug

    Also called AZD9833

    Subjects will be administered a single oral dose of Camizestrant on Day 1 of treatment period 1 and treatment period 3.

  • ItraconazoleDrug

    Subjects will be administered Itraconazole twice a day on Day 1 and once daily on Day 2 and Day 3 of treatment period 2, and once daily on Day 1, 2 and 3 of treatment period 3.

Study groups in NCT05551897
Study groupRoleWhat they receive
Treatment ArmExperimentalSubjects will receive a single oral dose of Camizestrant on Day 1 of treatment period 1. Following washout period of 7 to 10 days, subjects will receive Itraconazole on Days 1, 2, and 3 of treatment period 2, and single oral dose of Camizestrant plus a dose of Itraconazole on Day 1, followed by Itraconazole alone on Day 2 and Day 3 of treatment period 3.
Receives: Drug: Camizestrant; Drug: Itraconazole

What is being measured

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

  1. Area under plasma concentration time curve from zero to infinity (AUCinf) of Camizestrant

    To assess the effect of Itraconazole on AUCinf of Camizestrant.

    Measured: Day 1 to Day 4 (Period 1 and Period 3)

  2. Area under the plasma concentration curve from zero to the last quantifiable concentration (AUClast) of Camizestrant

    To assess the effect of Itraconazole on AUClast of Camizestrant.

    Measured: Day 1 to Day 4 (Period 1 and Period 3)

  3. Maximum observed plasma (peak) drug concentration (Cmax) of Camizestrant

    To assess the effect of Itraconazole on Cmax of Camizestrant.

    Measured: Day 1 to Day 4 (Period 1 and Period 3)

Secondary outcomes (2)
  1. Number of subjects with adverse events (AEs) and serious adverse events (SAEs)

    Safety and tolerability of Camizestrant alone and in combination with Itraconazole will be assessed.

    Measured: From Screening (Day -28 to Day -2) up to follow-up visit (7 to 14 days after last Pharmacokinetic Sample) [approximately 9 weeks]

  2. Number of subjects with adverse events leading to the discontinuation of study drug (DAEs)

    Number of subjects who discontinue the study drug due to adverse events will be assessed.

    Measured: From Day 1 (period 1) up to follow-up visit (7 to 14 days after last Pharmacokinetic Sample) [approximately 9 weeks]

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Camizestrant and Itraconazole in people with Healthy Subjects, 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 16 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 6 Jan 2023. 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?

Area under plasma concentration time curve from zero to infinity (AUCinf) of Camizestrant (time frame: Day 1 to Day 4 (Period 1 and Period 3)). 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 6 Jan 2023.
