What this Trial Is About

This phase II study aims to confirm the diagnostic performance and accuracy of 68Ga-ABS011 PET/CT in determining the HER2 expression status, and to evaluate 68Ga-ABS011's ability to drive changes in therapeutic treatment. 68Ga-ABS011 will be compared to the current standard of care (SOCa) diagnostic methods including immunohistochemistry (IHC), in situ hybridization (ISH) and imaging tools used for treatment response follow-up including Fluorodeoxyglucose F-18 (18F-FDG) positron emitted tomography (PET) and contrast enhanced computed tomography (ceCT).

Eligibility Criteria

Eligible

You may qualify if you...

  • Adult (≥ 18 years at the time of informed consent) male or female patient
  • Confirmed de novo or pre-treated metastatic breast cancer with multiple previous treatment lines allowed
  • Documented hormone receptor positive/HER2 negative, triple-negative, or HER2 positive metastatic breast cancer potentially eligible for HER2 targeted monotherapy
  • At least one target biopsiable, FDG positive, non-liver metastatic lesion ≥15 mm on contrast-enhanced CT
  • Willingness to undergo at least one tumor biopsy
  • Male patients able to father children and female patients of childbearing potential agree to use effective contraception during the diagnostic and treatment follow-up phases
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2
  • Ability and willingness to provide written informed consent
Not Eligible

You will not qualify if you...

  • Primary (non-metastatic) breast cancer
  • Unwillingness to undergo at least one tumor biopsy
  • Refusal to repeat 18F-FDG PET/contrast-enhanced CT assessment if already completed prior to screening
  • Tumor lesions cannot be biopsied due to location, tissue type, or increased risk for serious comorbidities based on metastatic 18F-FDG PET/contrast-enhanced CT
  • Brain and liver metastases are the only metastatic sites
  • Life expectancy less than 3 months
  • Pregnancy or breastfeeding
  • Inadequate organ function indicated by significant renal impairment (GFR <30 ml/min/1.73m2), low neutrophil count (<1,500 cells/mm3), elevated bilirubin (~1.5 x ULN unless Gilbert's syndrome), or high liver enzymes (>5 x ULN)
  • Known hypersensitivity to investigational product components or packaging
  • Increased bleeding risk or complications from biopsies, including inability to safely discontinue anticoagulation therapy
  • Known hypersensitivity or contraindication to iodinated contrast media not controllable by pre-medication
  • Inability to undergo PET/CT scanning (e.g., due to body size or claustrophobia)
  • Any condition likely to interfere significantly with study compliance, including psychological, social, or geographical factors
