What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 90 participants in total. It began in 2025-09-12 with a primary completion date of 2028-03-31.

Brief Summary

This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CD70-targeted CAR-T cell preparations, and to preliminarily observe the study drug in CD70-positive advanced malignant tumors. The pharmacokinetic characteristics of CAR-T cell preparations for the treatment of patients with CD70-positive advanced malignancies were obtained and the recommended dose and infusion schedule.

Eligibility Criteria

Inclusion Criteria: 1. Age ≥18 years, regardless of gender; 2. Histologically or cytologically confirmed advanced/metastatic solid tumors (tumors with positive CD70 expression, confirmed histopathological ly with IHC 3+ score); 3. Failed or intolerant to standard second-line treatments (at least one of the following: tyrosine kinase inhibitors (TKIs), poly(ADP-ribose) polymerase inhibitors (PARPi), anti-angiogenic therapy; disease progression or inability to tolerate surgery, chemotherapy, radiotherapy, or targeted therapy); 4. At least one measurable lesion per RECIST 1.1 criteria, with measurable lesions defined as: 1. Extranodal lesions with a long axis ≥10mm on CT scan; 2. Lymph node lesions with a short axis ≥15mm on CT scan; 3. CT slice thickness ≤5mm. 5. ECOG performance status of 0-2 ; 6. Expected survival ≥12 weeks; 7. No history of severe psychiatric disorders; 8. Adequate organ function as defined by the following: 1. Hematology: White blood cell count \>2.0×10⁹/L, neutrophils \>0.8×10⁹/L, lymphocytes \>0.5×10⁹/L, platelets \>50×10⁹/L, hemoglobin \>90g/L; 2. Cardiac: Echocardiogram showing left ventricular ejection fraction (LVEF) ≥50%, and ECG with no significant abnormalities; 3. Renal: Serum creatinine ≤2.0×ULN; 4. Hepatic: ALT and AST ≤3.0×ULN (may be relaxed to ≤5.0×ULN in cases with liver tumor infiltration); total bilirubin ≤2.0×ULN (may be relaxed to ≤3.0×ULN in cases with Gilbert's syndrome or liver tumor infiltration); 5. Oxygen saturation ≥92% without supplemental oxygen; 9. Ability to undergo single or venous blood collection, with no contraindications to cellular collection; 10. Female subjects must agree to use reliable contraception (excluding fertility awareness methods) from the time of informed consent until 1 year after CAR-T cell infusion; 11. Subject or authorized guardian agrees to participate in the trial and signs the informed consent form (ICF), indicating understanding of the trial's purpose and procedures and willingness to participate. Exclusion Criteria: 1. Prior treatment with anti-CD70 therapies; 2. Active/symptomatic central nervous system (CNS) metastasis or meningeal metastasis: Subjects with treated brain metastases are eligible if treatment was completed ≥4 weeks prior to screening and there is no evidence of progression on imaging; 3. Prior treatments within specified time frames: 1. Participation in other interventional clinical trials within 3 months before cell infusion (for unapproved drugs, the last dose must be ≥3 months prior; for approved drugs, ≥5 half-lives prior to cell infusion); 2. Received chemotherapy or targeted therapy within 2 weeks prior to blood collection or within 5 half-lives of the drug (whichever is shorter); 3. Received \>10mg/day prednisone (or equivalent) within 2 weeks prior to blood collection, unless for adrenal replacement or inhaled/local steroids (except for active autoimmune disease); 4. Received live attenuated vaccines within 4 weeks prior to screening; 4. Active infection requiring systemic treatment or uncontrolled infection within 1 week before screening; 5. History of any other malignancy within the past 3 years, except for treated and stable non-melanoma skin cancer or malignancies treated with curative intent and no evidence of active disease for ≥3 years; 6. Cardiovascular conditions: 1. NYHA Class III or IV heart failure; 2. Myocardial infarction or coronary artery bypass graft (CABG) within 6 months prior to screening; 3. Clinically significant ventricular arrhythmias or unexplained syncope (excluding vasovagal or dehydration); 4. Severe non-ischemic cardiomyopathy; 7. Active or uncontrolled autoimmune diseases such as Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus, systemic vasculitis, etc.; 8. Positive for HBsAg or HBcAb with elevated HBV DNA in peripheral blood; positive for HCV antibodies with detectable HCV RNA levels; positive for HIV antibodies; positive syphilis test; 9. Toxicity from prior anti-tumor treatments has not resolved to baseline or ≤grade 1, except for alopecia or peripheral neuropathy; 10. History of venous thromboembolism (e.g., pulmonary embolism) requiring ongoing anticoagulation treatment, or meeting one of the following criteria: 1. Severe bleeding (grade 3 or 4) lasting for ≥30 days; 2. Post-thrombotic sequelae (e.g., persistent dyspnea and hypoxia) due to venous thromboembolism; 11. Pregnant or breastfeeding women; 12. Other conditions that, in the opinion of the investigator, make the subject unsuitable for participation in the trial.
