Pancreatic Cancer
Conditions
Brief summary
This is a single-center, single-arm, open-label clinical study of 177Lu-CTR-FAPI injection in the treatment of patients with advanced, metastatic solid tumors i.e. pancreatic cancer, to assess safety, radio-dosimetry, and efficacy per RESIST 1.1.
Interventions
DRUG177Lu-CTR-FAPI
The medication is administered intravenously, with a single dose of 200 mCi (7.4 GBq) ±10%, administered once every 6 ± 2 weeks. The planned course consists of 4 doses, or until the radiation safety threshold for major organs is reached based on radiation dosimetry assessment.

Patients with HR/HER2-negative advanced or metastatic breast cancer who have progressed after or are intolerant to at least 2 lines of systemic therapy; 4. Patients with advanced or metastatic high-grade soft tissue sarcoma (excluding chordoma) who have progressed after or are intolerant to at least 1 line of systemic therapy; 5. Patients with advanced or metastatic pancreatic cancer who have progressed after or are intolerant to at least 1 line of systemic therapy. * 2: Age \>= 18 years, regardless of sex; * 3: Able to understand and sign informed consent and willing and able to comply with study and follow-up procedures; * 4: ECOG performance status score of 0 or 1; * 5: FAP expression in tumor lesions confirmed positive by FAPI PET/CT; * 6: Agree to provide archived or fresh tumor tissue for immunohistochemical evaluation (if available); * 7: At least 1 measurable lesion according to RECIST 1.1 criteria; * 8: Previous anti-tumor toxicities recovered to grade 0-1; * 9: Organ function meets requirements before first administration; 1.
