Korábbi kezelés

• For Cohort 1 and Cohort 2: Prior treatment for pancreatic cancer, including chemotherapy except for 1 - 4 cycles of mFOLFIRINOX, radiation therapy, immunotherapy, etc.
• Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids.
• Patients do not agree to use adequate contraception (vasectomy or barrier method of birth control) prior to study entry, for the duration of study participation and for 3 months after DaRT insertion.

Más betegség

• Known hypersensitivity to any of the components of the treatment.
• Clinically significant cardiovascular disease, e.g. cardiac failure of New York Heart Association classes III-IV, uncontrolled coronary artery disease, cardiomyopathy, uncontrolled arrhythmia, uncontrolled hypertension, or history of myocardial infarction in the last 12 months.
• Patients with uncontrolled intercurrent illnesses including, but not limited to an active infection requiring systemic therapy or a known psychiatric or substance abuse disorder(s) that would interfere with cooperation with the requirements of the trial or interfere with the study endpoints.
• Has a known additional malignancy that is progressing or requires active treatment.
  • Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy, low risk prostate cancer, or in situ cervical cancer.
• Patients who are at high risk of complications from radiation due to genetic conditions/mutations, inflammatory bowel disease, or connective tissue disease.
