About this trial

This is a single-center, double-arm, open-label study. this study plans to evaluate the safety and efficacy of CD70-targeting CAR-T cells in the treatment of CD70-positive advanced/metastatic Gynecologic Cancer, and obtain recommended doses and infusion patterns.

Eligibility criteria

Qualifiers

Age ≥18 years old;

Advanced/metastatic gynecological tumor confirmed by histopathology or cytology (paraffin sections or fresh biopsy tumor tissue specimens) (CD70 positive tumor expression (CD70 positive tumor confirmed by histology or pathology (IHC 3+));

Failure or intolerance after standard treatment (disease progression or intolerance such as surgery, chemotherapy, radiotherapy, targeted therapy, etc.), and currently no effective treatment;

According to the RECIST version 1.1 standard, there is at least one measurable diameter and evaluable target lesion. Measurable lesions are defined as: extranodal lesions with CT scan diameter ≥10mm, lymph node lesions with CT scan diameter ≥15mm, scan layer thickness ≤ 5mm, and have not received local treatment;

Disqualifiers

Received anti-CD70 drug therapy before screening;

Active/symptomatic central nervous system metastasis or meningeal metastasis at the time of screening; Treated subjects with brain metastases can only be enrolled if no radiographically demonstrated progression is demonstrated ≥4 weeks after the end of treatment.

Participated in other interventional clinical studies before screening, including: the time of last use of unmarketed new drugs less than 3 months from cell transfusion, or the time of last use of marketed drugs less than 5 half-lives from cell transfusion;

Received anti-tumor therapy such as chemotherapy or targeted therapy within 2 weeks of preapheresis or at least 5 half-lives (whichever is shorter); Received systemic radiation within 4 weeks and local radiation within 2 weeks; Or received radioactive drugs (strontium, samarium) within 8 weeks prior to treatment.
