About this study
The purpose of the study is to see if using an investigational drug called [18F]FMISO with PET/MRI imaging can help monitor and predict the effect of trastuzumab (Herceptin) on chemotherapy in patients diagnosed with advanced HER2 positive breast cancer. This study is for imaging purposes only and is not a treatment study. The results of this study will not change a patient's clinical treatment plan but it may help physicians and researchers better understand how best to treat patients with breast cancer in the future.
Read the detailed description
There are 2 groups or cohorts in this study. The cohort patient's are in is based on their clinical treatment plan set by your physician. The number of imaging visits and timing of visits will be determined by what cohort they are in.
If the patient is in cohort #1, they will make 4 visits to UAB. They will be scheduled for a pre-study or screening visit. During the pre-study visit, once consented, they will have a blood draw to determine kidney function, and a pregnancy test if they are a woman of childbearing potential. Their vital signs will be taken, they will be asked to fill out an MRI questionnaire, and they will have a PET/MRI fit test. If eligible for the study, they will be scheduled for the first PET imaging visit which will occur before they start chemotherapy. During this PET imaging visit, they will have a pregnancy test if they are a woman of childbearing potential. A plastic catheter will be placed into a vein in their arm and they will then be positioned in the PET/MRI scanner. Once positioned, they will be injected with the investigational radioactive drug, [18F]FMISO. They will then be imaged for up to 90 minutes during which time they will receive an FDA approved contrast agent called Prohance (gadoteridol). Once all the procedures are complete, the catheter will be removed and they may resume all normal activities. The patient will receive a follow-up phone call within 24-48 hours of your injection to be sure they are not experiencing any adverse events. Their second imaging visit will be scheduled after they receive therapy with Herceptin alone and within 10 days before their first cycle of combination therapy including Herceptin. During the second PET imaging visit, the same procedures will be followed as were performed during your first PET imaging visit. They will receive a follow-up phone call within 24-48 hours of your injection to be sure you are not experiencing any adverse events. Their third PET imaging visit will be scheduled after their first cycle of combination therapy including Herceptin and within 10 days before starting their second cycle of combination therapy including Herceptin. During the third PET imaging visit, the same procedures will be followed as were performed during their first and second PET imaging visits. The patient will receive a follow-up phone call within 24-48 hours of their injection to be sure they are not experiencing any adverse events.
If the patients are in cohort #2, they will make 3 visits to UAB. The patients will be scheduled for a pre-study or screening visit. During the pre-study visit, once consented, they will have a blood draw to determine kidney function, and a pregnancy test if they are a woman of childbearing potential. Their vital signs will be taken, they will be asked to fill out an MRI questionnaire, and they will have a PET/MRI fit test. If eligible for the study, they will be scheduled for the first PET imaging visit which will occur before they start chemotherapy. During this visit, they will have a pregnancy test if they are a woman of childbearing potential. A plastic catheter will be placed into a vein in their arm and they will then be positioned in the PET/MRI scanner. Once positioned, the patient will be injected with the investigational radioactive drug, [18F]FMISO. They will then be imaged for up to 90 minutes during which time they will receive an FDA approved contrast agent called Prohance (gadoteridol). Once all the procedures are complete, the catheter will be removed and the patient may resume all normal activities. They will receive a follow-up phone call within 24-48 hours of your injection to be sure they are not experiencing any adverse events. Your second PET imaging visit will be scheduled after your first cycle of combination therapy including Herceptin and within 10 days before starting the second cycle of combination therapy including Herceptin. During the third PET imaging visit, the same procedures will be followed as were performed during the first PET imaging visits. The patient will receive a follow-up phone call within 24-48 hours of your injection to be sure they are not experiencing any adverse events.
We will follow the patients every 6 months for 5 years by reviewing their medical records to see how they are doing.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing [18F]FMISO PET/MRI imaging in people with HER2-positive Breast Cancer, run by University of Alabama at Birmingham at 1 site in United States.
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 6 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: looking for participants now, as of the sponsor's last update on 17 Aug 2026. 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 States. 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?
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?
Contact Anna Sorace, PhD (205-934-3116, asorace@uabmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Baseline measure of PET standardized uptake value (SUV). (time frame: Baseline). The study lists 6 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 17 Aug 2026.
