简要总结

Dynamic observationaL study with PET of 68Ga-HER2-affibody in anti-HER2 treatment

详细描述

Participants participated in the screening period visit, and received HER2-PET and 18 F-FDG PET/CT examinations before receiving tumor treatment, after receiving 2 cycles of chemotherapy, and after disease progression. Patients of first-line received docetaxel combined with trastuzumab±pertuzumab regimen, and patients of second-line received T-DM1 monotherapy or capecitabine combined with pyrrotinib regimen.

排除标准

  • The subject has untreated central nervous system (CNS) metastases.

  • Received systemic therapy such as chemotherapy, molecular targeted therapyment;received endocrine therapy within 2 weeks before enrollment.
  • Patients with other malignant tumors within 3 years or at the sametime(except for cured skin basal cell carcinoma and cervical carcinomain situ).
  • Have undergone major surgical procedures or significant trauma within 4 weeks prior to randomization, or are expected to undergo major surgery.
  • Pregnant women, lactating female, or women of childbearing age who are unwilling to take effective contraceptive measures.
  • Have a history of allergies to the drug components of this regimen.
  • Patients with active HBV and HCV infection; stable hepatitis B after drug treatment (HBV virus copy number is higher than the upper limit of reference value) and cured hepatitis C patients (HCV virus copy number exceeds the lower limit of detection method).
  • History of immunodeficiency, including HIV positive, or other acquired or congenital immunodeficiency disease, history of organ transplantation.
  • History of cardiac dysfunction, include(1)angina (2)clinical significant arrythmia or require drug intervention (3)myocardial infarction (4)heart failure (5) other cardiac dysfunction (judged by the physician); any cardiac or nephric abnormal ≥ grade 2 found in screening.
  • Female patients who are pregnancy, lactation or women who are ofchildbearing potential tested positive in baseline pregnancy test.
  • Childbearing female who refuse to accept any contraception practice.
  • Determined by the physician, any serious coexisting disease might be harmful to the patient's safety or avoid the patients from accomplishing the treatment(e.g serious hypertension, diabetes, thyroid dysfunction,active infection etc.).
  • History of neurological or psychiatric disorders, including epilepsy or dementia.
  • Severe infections within 4 weeks prior to first dose (eg, intravenous infusion of antibiotics, antifungal or antiviral drugs according to clinical protocols), or unexplained fever (T > 38.3 °C ) during screening or prior to first administration
