Brief Summary:
The study will evaluate [68Ga]ABY-025 for PET imaging of HER2 expression in subjects with HER2-positive or HER2-negative breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: [68Ga]ABY-025 Phase 1 Phase 2

Detailed Description:

Open-labeled, exploratory, single center study.

  1. Group 1 (dose-finding) Six subjects with HER2-positive primary tumor status and four subjects with HER2-negative status. [68Ga]ABY-025 PET with low dose (100 μg) of ABY-025 peptide is performed, followed by a repeated PET within three weeks using high dose (500 μg) ABY-025 peptide (radioactivity maximum 500 MBq). A third [68Ga]ABY-025 PET will be performed in the HER2-positive subgroup only, when signs of progressive disease are found at routine clinical evaluation or else latest after 12 months regardless of disease status, then using the ABY-025 peptide dose previously determined to be preferable.
  2. Group 2 Ten subjects with HER2-positive primary tumor status. [68Ga]ABY-025 PET is performed using the ABY-025 peptide dose determined to be preferable during the dose-finding part of the study, followed by a second [68Ga]ABY-025 PET investigation at signs of progressive disease or else latest after 9 months.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. PET image analysis: Standardized Uptake Value (SUV) and uptake kinetics of [68Ga]ABY-025 in breast cancer lesions and normal tissues [ Time Frame: Day 0 ]

Secondary Outcome Measures :
  1. SUV in metastases where biopsy results with HER2 status by IHC/FISH are available [ Time Frame: Day 0 ]
  2. SUV for each measured lesion, and appearance or disappearance of lesions, after progression or 9-12 months therapy [ Time Frame: Up to 1 year ]
  3. SUV for each measured lesion and number of detectable lesions, obtained with a low (100 μg) or high (500 μg) injected amount of ABY-025 peptide in the same subject [ Time Frame: Day 0 & 1-3 weeks ]
  4. SUVs for all measured lesions obtained with a low (100 μg) or high (500 μg) injected where biopsy results with HER2 status by IHC and FISH are available [ Time Frame: Day 0 ]
  5. Incidence and severity of adverse events [ Time Frame: Day 0 to 42 ]
  6. Anti-Drug Antibody assay at 3 and 6 weeks [ Time Frame: Day 0 to 42 ]
  7. Blood radioactivity kinetics and dosimetry of [68Ga]ABY-025 [ Time Frame: Day 0 ]
  8. Uptake of [68Ga]ABY-025 coinciding with metastatic lesions visible on [18F]FDG PET and focal uptake in regions without pathological findings on [18F]FDG PET [ Time Frame: Day 0 ]
