About this study

Official title: SONImage Study: Can Molecular Imaging Predict Outcome to First-line Endocrine Treatment ± CDK 4/6 Inhibition in Advanced ER+ Breast Cancer

SONImage is a multicenter prospective imaging side study, in which a baseline FES-PET is added to conventional work up, in 100 patients with ER+ MBC who will receive endocrine treatment ± CDK 4/6 inhibition within the SONIA study (NCT03425838). SONImage will be executed in two Dutch centers: UMCG and Amsterdam UMC-location VUMC. The aim of the SONImage study is to (1) assess the relationship between FES/FDG-PET heterogeneity patterns at baseline and PFS for first-line endocrine treatment ± CDK 4/6 inhibition in ER+ MBC, and (2) to further improve that by developing a prediction model, within the SONIA study. This molecular imaging based multivariable prediction model may provide a unique measure of benefit of adding CDK 4/6 inhibition to first-line endocrine treatment, allowing patients and providers to weigh individual benefits and (long term) burden for optimized treatment decisions.

Read the detailed description

Estrogen receptor positive (ER+) breast cancer is the most common cancer and the most frequent cause of cancer-related death in women in the Western World. Cyclin-dependent kinase 4 and 6 (CDK 4/6) inhibitors improve outcome, when added to standard first- and second-line endocrine therapy. However, they also add patient- and financial burden due to (long term) increased toxicity and hospital visits. Therefore, benefits of additional CDK 4/6 inhibitors should be weighed against their burden. Tools to support such treatment decisions by patients and providers are currently lacking. Whole body heterogeneity of ER expression, measured by 16α-[18F]fluoro-17β-estradiol (FES)-PET scan and 18F-fluorodeoxyglucose (FDG)-PET scan was related to time to progression on combined treatment in previous work. Therefore in SONImage a baseline FES-PET is added to conventional work up, in 100 patients with ER+ MBC who will receive first line endocrine treatment ± CDK 4/6 inhibition within the SONIA study. The objectives are 1. to correlate PFS1 (according to SONIA criteria) to baseline FES/FDG-PET heterogeneity; 2. to assess interaction between baseline FES/FDG-PET heterogeneity, treatment allocation, and PFS1 (according to SONIA criteria); 3. to correlate response measurements of individual lesions to baseline FES/FDG heterogeneity and detailed FES/FDG imaging features; 4. to develop a multivariable model to predict individual PFS benefit to first-line AI ± CDK 4/6 inhibition, based on detailed FES/FDG image features and standard clinicopathological information, in n=100 SONIA patients; 5. to validate this prediction model in two independent patient cohorts with baseline FES/FDG-PET scans (Dutch IMPACT-MBC trial; international ET-TRANSCAN trial). This molecular imaging based multivariable prediction model may provide a unique measure of benefit of adding CDK 4/6 inhibition to first-line endocrine treatment, allowing patients and providers to weigh individual benefits and (long term) burden for optimized treatment decisions. Particularly for the approximately 25% of patients with ER+ MBC who have an excellent- or poor outcome despite CDK 4/6 inhibition in the first-line, this could have profound implications, as they may refrain from combined treatment. Ultimately, this could potentially contribute to FES/FDG-PET based treatment decisions in clinical practice, reduction of unnecessary toxicity and costs, while improving patient outcome and QoL.

What participants receive

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

  • FES-PET scan, and possibly one additional visit for an FDG-PETOther

    One visit to either the UMCG or Amsterdam UMC-location VUMC is required for the FES-PET scan, and possibly one additional visit for an FDG-PET. A FES- or FDG-PET scan plus low dose CT will each induce an extra radiation burden of about 6.1 mSv (210 MBq injected for an average patient of 70 kilogram body weight).

What is being measured

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

  1. Progression-free survival after first line treatment (PFS1)

    Progression-free survival after first line treatment (PFS1) defined as time from randomization until objective disease progression, symptomatic deterioration, or initiation of a new therapeutic agent on first line treatment, death, or progression during a break in initial therapy and without further therapy within one month, whichever occurs first.

    Measured: 5 years

Secondary outcomes (3)
  1. Patient response

    Per patient response according to RECIST1.1

    Measured: 5 years

  2. Response measurement individual lesion

    Change in size (=response measurement) per individual lesion at the largest measurable response measured on CT compared to baseline CT

    Measured: 5 years

  3. Response measurement target lesions

    • Per patient trajectory of change in size of target lesions according to RECIST 1.1, from baseline CT until CT at progression of disease.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A study testing FES-PET scan, and possibly one additional visit for an FDG-PET in people with Breast Cancer, run by The Netherlands Cancer Institute at 2 sites in Netherlands.

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 3 inclusion and 3 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 18 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. 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.

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?

Progression-free survival after first line treatment (PFS1) (time frame: 5 years). 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 18 Apr 2025.
