What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Time periods mentioned: 24 weeks
  • Procedures mentioned: MRI scans

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "This clinical trial examines an investigational scan (64Cu-DOTA-trastuzumab positron emission tomography \[PET\]/magnetic resonance imaging \[MRI\]) in imaging patients with HER2+ breast cancer that has spread to the brain (brain metastasis)."
  • "Diagnostic procedures, such as 64Cu-DOTA-trastuzumab PET/MRI, may help find HER2+ breast cancer that has spread to the brain and determine whether cancer in the brain takes up trastuzumab, which may predict for response to trastuzumab deruxtecan (the standard of care chemotherapy)."
  • "Patients then receive 64Cu-DOTA-trastuzumab IV and then undergo PET/MRI scan on day 1."
  • "Patients undergo repeat brain MRI every 6 weeks for 24 weeks and then every 9 weeks until disease progression."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

This clinical trial examines an investigational scan (64Cu-DOTA-trastuzumab positron emission tomography \[PET\]/magnetic resonance imaging \[MRI\]) in imaging patients with HER2+ breast cancer that has spread to the brain (brain metastasis). Diagnostic procedures, such as 64Cu-DOTA-trastuzumab PET/MRI, may help find HER2+ breast cancer that has spread to the brain and determine whether cancer in the brain takes up trastuzumab, which may predict for response to trastuzumab deruxtecan (the standard of care chemotherapy).

Compensation is read from the study's own description and may be missing — always confirm with the study team.
