About this study

Official title: An Open Label, Randomised, Pre-surgical, Pharmacodynamics Study to Compare the Biological Effects of AZD9496 Versus Fulvestrant in Postmenopausal Women With ER Positive HER-2 Negative Primary Breast Cancer

This is an open label randomised multicentre pre-surgical pharmacodynamics study to compare and assess the biological effects of AZD9496 and fulvestrant in postmenopausal women with estrogen receptor (ER) positive (ER+), human epidermal growth factor receptor 2 (HER-2) negative (HER2-) primary breast cancer.

Patients will receive AZD9496 or fulvestrant and will have an on-treatment image

-guided core biopsy after 5-14 days of commencing treatment.

Read the detailed description

This is an open label, randomized, multi-centre study in postmenopausal women with primary ER+ HER2- breast cancer. Patients will be randomised to an oral dose of 250 mg bd AZD9496 or 500mg fulvestrant i.m. administered on one occasion. Patients diagnosed with primary breast cancer who are scheduled for surgery with curative intent will be consented to the study including consent to use the formalin fixed paraffin embedded (FFPE) diagnostic tumor biopsy sample and fresh frozen tumor biopsy sample (if available) for research purposes. Patients may also consent to provide an optional pretreatment fresh frozen tumor biopsy sample if this was not obtained at the time of initial diagnostic biopsy. If the diagnostic biopsy was taken ≥ 6 weeks prior to starting treatment or was not of sufficient quality, new tumor core biopsies (FFPE and fresh frozen) must be taken. Following the screening visit, eligible patients will be randomised to receive one of the following study treatments:

  • AZD9496 administered at 250 mg bd orally for 5-14 days commencing on Day 1, and continuing up to the day of biopsy OR
  • fulvestrant 500 mg administered as two consecutive 5 ml intramuscular injections on Day 1, one in each buttock.

After the morning dose of AZD9496 on the day of biopsy dosing will be stopped. If following initiation of AZD9496 treatment, dosing will be stopped if biopsy is postponed beyond Day 14. Patients will be considered not evaluable for the study if biopsy is postponed beyond day 14 of AZD9496/fulvestrant treatment initiation. Core tumor biopsies will be taken at either the time of definitive surgery or at a separate visit prior to surgery in the period between (and including) day 5 and day 14. Subjects who are scheduled to start a subsequent neoadjuvant therapy must have their core tumor biopsies performed before commencing neoadjuvant treatment.

    Evaluation of AZD9496 and fulvestrant activity in the tumour by assessment of pharmacodynamics biomarker changes i.e. ER expression

    Measured: Tumour biopsy taken at baseline within 6 weeks of planned start of study treatment; on-treatment tumour biopsy taken following 5-14 day on study treatment

Secondary outcomes (7)
  1. Pharmacodynamics changes to progesterone receptor (PgR) expression following treatment with AZD9496 or fulvestrant

    Evaluation of AZD9496 and fulvestrant activity in the tumour by assessment of pharmacodynamics biomarker changes i.e. PgR expression

    Measured: Tumour biopsy taken at baseline within 6 weeks of planned start of study treatment; on-treatment tumour biopsy taken following 5-14 day on study treatment

  2. Pharmacodynamics changes to Ki67 protein biomarker expression following treatment with AZD9496 or fulvestrant

    Evaluation of AZD9496 and fulvestrant activity in the tumour by assessment of pharmacodynamics biomarker changes i.e. Ki67 protein biomarker expression

    Measured: Tumour biopsy taken at baseline within 6 weeks of planned start of study treatment; on-treatment tumour biopsy taken following 5-14 day on study treatment

  3. Safety and tolerability of AZD9496

    Safety and tolerability will be assessed in terms of adverse events (AEs), laboratory data, vital signs and ECG changes.

    Measured: From first dose until 28 days after last dose of AZD9496

  4. Safety and tolerability of fulvestrant

    Safety and tolerability will be assessed in terms of adverse events (AEs), laboratory data and vital signs

    Measured: From first dose until 28 days after fulvestrant

  5. Plasma concentration of AZD9496 - stand alone biopsy visit option

    Determination of AZD9496 concentrations in plasma

    Measured: Blood samples collected close as possible to time of biopsy, 1-2 hours after biopsy and optional 3-4 hours after biopsy

  6. Plasma concentration of fulvestrant

    Determination of fulvestrant concentration in plasma

    Measured: A blood sample will be collected anytime before biopsy.

  7. Plasma concentration of AZD9496 - on the table biopsy option

    Determination of AZD9496 concentration in plasma

    Measured: Blood samples collected close as possible to time of biopsy, at least 2 hours after biopsy and 8-12 hours after last dose or at discharge which is defined as up to 12 hours after last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Standard Arm - Fulvestrant and AZD9496 in people with Postmenopausal Women With ER+ HER2- Primary Breast Cancer, run by AstraZeneca at 12 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 9 inclusion and 22 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 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United Kingdom, Germany. 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?

Pharmacodynamics changes to estrogen receptor (ER) expression following treatment with AZD9496 or fulvestrant (time frame: Tumour biopsy taken at baseline within 6 weeks of planned start of study treatment; on-treatment tumour biopsy taken following 5-14 day on study treatment). 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 NCT03236974, which also lists 1 linked publication.

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 Feb 2020.
