• 11. Any melanoma treatment methods, including radiotherapy, chemotherapy, endocrine therapy, targeted therapy, immunotherapy, tumor embolization, or traditional Chinese medicine/herbal medicine treatment with anti-tumor indications, must be stopped 28 days before infusion. If a small molecular targeted drug was used in the previous treatment, the withdrawal time can be shortened to 5 half-lives of the drug used;

Exclusion Criteria:

• 1. Participation in a clinical trial of another drug or biologic therapy or receipt of a comparable cellular therapy within 28 days prior to infusion;

• 3.Has received live attenuated vaccination after signing informed consent or is scheduled to receive it during the study;
• 4.Has not recovered from a prior procedure or treatment-related adverse reaction to ≤ grade 1 nci ctcae 5.0 (except for toxicities such as alopecia, etc., which in the judgment of the investigator pose no safety risk);
• 5. Known history of allergy to streptomycin, ciprofloxacin, or micafungin or allergy to any component of the infused product formulation;
• 6.Uncontrolled co-morbidities including, but not limited to, uncontrolled arterial hypertension (systolic blood pressure ≥160 mmhg and/or diastolic blood pressure ≥100 mmhg) even with standardized treatment or any unstable cardiovascular disease including transient ischemic attack, cerebrovascular accident, myocardial infarction, unstable angina pectoris within 6 months prior to enrollment; new york heart association ( nyha class iii or iv congestive heart failure with an ejection fraction <50%; or severe cardiac rhythm or conduction abnormalities, such as ventricular arrhythmias, degree ii-iii atrioventricular block, etc., requiring clinical intervention; ecg results showing clinically significant abnormalities or a qtcf ≥450ms (if the first test is abnormal, it may be retested at least 5 minutes apart twice and the combined result/mean value to determine eligibility) ;
• 7.Patients with esophageal or gastric varices that require immediate intervention (e.g., taping or sclerotherapy) or are considered to be at high risk for bleeding based on the opinion of the investigator or consultation with a gastroenterologist or hepatologist, have evidence of portal hypertension (including splenomegaly detected on imaging), or have a prior history of variceal bleeding must have undergone endoscopic evaluation within 3 months prior to enrollment;
• 8.Uncontrolled metabolic disorders, such as diabetes mellitus known to be uncontrolled, or other non-malignant organ or systemic diseases or secondary reactions to cancer, and which can lead to higher medical risk and/or uncertainty in survival evaluation;
• 9.Hepatic encephalopathy, hepatorenal syndrome or child-pugh class b or more severe cirrhosis, liver failure;
• 10.Comorbidity with other serious organic or psychiatric disease;
• 11.Have an active systemic infection requiring treatment with positive blood cultures or imaging evidence of infection, including but not limited to active tuberculosis;
• 12.Be hiv-positive, have a positive serologic test for syphilis, or have clinically active hepatitis a, b, or c, including viral carriers: Hepatitis b, excluding those who are HBsAg-positive; hepatitis c, excluding those who are HCVAb-positive;
• 13.Active autoimmune diseases that still require systemic steroid hormones or other immunosuppressive drugs during the screening period (greater than 10 mg/ day of prednisone or equivalent doses of other hormones);
• 14.Any nci ctcae5.0 immune-related adverse effect (irae) grade ≥ 3 during any prior period of immunotherapy receipt;
• 15.History of organ allograft, allogeneic stem cell transplantation and renal replacement therapy; History of allogeneic t-cell and nk-cell therapy;
• 16. Pulmonary fibrosis, interstitial lung disease (both past history and current), and acute lung disease; Patients with obstructive or restrictive lung disease with FEV1(forced expiratory volume in 1 second) of lung function ≤70%;
• 17.Clinically uncontrollable third space effusions, such as pleural and abdominal effusions that cannot be controlled by drainage or other means prior to enrollment;
• 18.Patients with clinically symptomatic central nervous system metastases (e.g., cerebral edema, need for hormonal intervention, or progression of brain metastases). Patients with prior treatment for brain metastases, such as clinical stability (mri) that has been maintained for at least 2 months and who have discontinued systemic hormone therapy (dose >10 mg/day prednisone or other equipotent hormone) for >4 weeks may be included;
• 19.Women who are pregnant or breastfeeding;
