Evaluating the Safety and Efficacy of 177Lu-LNC1011 Injection in a Single-Center, Single-Arm, Open Study in Patients with Prostate-Specific Membrane Antigen (PSMA)-Positive Metastatic Desmoplasia-Resistant Prostate Cancer

This is a prospective, single-center, single-arm, open IIT clinical study evaluating the safety and anti-tumor efficacy of 177Lu-LNC1011 Injection in patients with PSMA-positive metastatic desmoplasia-resistant prostate cancer (mCRPC). Thirteen patients are expected to be enrolled. Subjects will be required to sign an informed consent form prior to screening, and successful screened subjects will be treated with 177Lu-LNC1011 Injection as 75 mCi (2.78 GBq) intravenously every 6 weeks for a total of no more than 6 doses during the treatment period. Subjects will be monitored for safety and anti-tumor efficacy after dosing during the treatment period.

Inclusion criteria

• ≥18 years old, male.

• a physical status score of ≤2 according to Eastern Cooperative Oncology Group (ECOG) criteria.
• PSMA positivity confirmed by 68Ga -PSMA PET/CT.
