简要总结
To explore the safety, tolerability, initial efficacy, pharmacokinetic profile and radiation dosimetry of lutetium [177Lu]-FAP-75 in the treatment of patients with advanced solid tumors.
详细描述
This is a prospective, open, dose-exploring clinical study of Lutetium [177Lu]-FAP-75 in the treatment of patients with advanced solid tumors. The study was divided into two stages, the first stage was dose exploration study, and the second stage was case expansion study. In the first phase of this study, several dose groups were designed. Subjects may receive only one of these doses and may not receive multiple doses in the same subject. The drug was administered every 6 weeks, and the DLT observation period was 6 weeks after the first dose. Firstly, the first dose safety introduction of human body was carried out. Based on the results of the preclinical study of this product, an appropriate number of enrolled subjects in the first and second stages were selected to enter the PK and radiation dosimetry detection groups. After the end of the DLT observation period, subjects who met the criteria for continued dosing were allowed to continue to receive the investigational drug therapy for subsequent cycles. For all participants enrolled in this study, the study process included a screening period, a treatment period and a follow-up period. In the course of the trial, extended studies of other tumor species can be conducted based on new advances and results of clinical studies of similar drugs to further explore the safety, tolerability and initial effectiveness of specific tumor types.

排除标准
- •Known significant weight loss (>10%) within 28 days prior to signing the informed consent.
- •Prior and follow-up treatment:
- •Received any radionuclide therapy or radiotherapy within 6 months before enrollment.
- •Prior treatment with any FAP target nuclide.
- •Received anti-tumor therapy such as surgery (except diagnostic biopsy and drainage of serosal effusion), chemotherapy, immunotherapy, and monoclonal antibodies within 4 weeks prior to admission; received anti-tumor endocrine drugs within 2 weeks; received nitrosourea or mitomycin chemotherapy within 6 weeks; eluted oral targeted therapy drugs with less than 5 half-lives or 4 weeks (whichever is shorter).
- •Received any other investigational drug treatment within 4 weeks prior to enrollment.
- •Any surgical procedures requiring general anesthesia and significant incisions (e.g., central venous access, percutaneous feeding tube insertion) within 6 weeks of enrollment (expected surgery).
- •Combined with the following diseases:
- •Patients with meningeal metastasis or diffuse central nervous system metastasis or active central nervous system metastasis who require any radiotherapy, gamma knife, surgery, or medication to control the symptoms of metastasis 1 month prior to screening are excluded. Patients with a limited number of stable central nervous system metastases could be enrolled.

The exception is for cured malignancies with a low risk of metastasis and death, such as non-metastatic skin basal cell carcinoma or skin superficial squamous cell carcinoma.
- •Serious infections occurred within 4 weeks prior to enrollment, such as severe pneumonia requiring hospitalization, bacteremia, infection complications, etc., and signs and symptoms of infection within 2 weeks prior to enrollment requiring intravenous antibiotic treatment (except for prophylactic antibiotic use).
研究组 & 干预措施
treatment group
Lutetium [177Lu]-FAP-75 accumulates at the tumor site, and beta rays act on surrounding tumor cells, causing tumor cell apoptosis.
