Study summary

The investigators want to find out if the treatments used in this study are helpful to patients that are diagnosed with hormone receptor positive metastatic breast cancer. The investigators want to also look at any side effects that could happen while patients are on the study treatments. The investigators want to see if there are any changes that could show us if your cancer is responding to the study treatments.

Read the detailed description

The study design is a phase II design. Eligible patients will undergo staging work up and start treatment. Every 28-day period (4 weeks) will count as a cycle. Medical evaluations will be performed every 4 weeks and staging work up will be repeated every 12 weeks.

The primary objective of the study is to assess progression free survival (PFS) of treatment with exemestane and sunitinib in post¬menopausal subjects with hormone receptor positive (ER-positive and/or PR-positive) unresectable locally advanced or metastatic breast cancer subjects who have progressed on prior hormonal treatment.

In addition we want to:

  1. Obtain assessments of overall response rate (ORR), clinical benefit rate (CBR), and overall survival (OS).
  2. Determine the safety and tolerability of the combination regimen.
  3. Study molecular changes in tissue biopsies, circulating tumor cells (CTCs), and circulating endothelial cells (CECs), and explore associations with treatment response and resistance.
  1. Blood samples will be drawn for enumeration and profiling of circulating tumor cells and circulating endothelial cells at study entry (prior to starting study medications), four weeks after starting study medications, twelve weeks after starting study medications and at disease progression. These samples will be strongly encouraged but the patients may decline any or all of them without impacting their eligibility or continuation on the study.
  1. If the patient participating on the study has an easily accessible breast mass or metastatic lesion (e.g. lymphadenopathy, skin metastasis, chest wall metastasis), a core needle or punch biopsy will be obtained at study entry (prior to starting study medications), four weeks after starting study medications, and at disease progression. These biopsies will be strongly encouraged but the patients may decline any or all of them without impacting their eligibility or continuation on the study.

Terms in these criteria, in plain language(12)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
