Eligibility criteria
Qualifiers
Aged 60 years or older;
Diagnosis of malignant melanoma confirmed by pathological histology or cytology examination.
According to the 8th edition of AJCC staging, patients with unresectable stage III or IV melanoma;
One or more lesions evaluable by RECIST1.1 standards.
Disqualifiers
Received treatment involving PD-1, PD-L1, or CTLA-4 antibody regimen within the past 6 months;
Patients who have received treatment with thymosin, thymopentin, or thymosin a-1d within 3 months prior to enrollment.
Presence of symptomatic central nervous system (CNS) metastases and/or carcinomatous meningitis. For subjects with previously treated CNS metastases, if the subject's condition is stable (no evidence of radiographic progression for at least weeks prior to the first administration of the study intervention, and all neurological symptoms have returned to baseline), repeat radiographic examination confirms no evidence of new brain metastases or enlargement of existing brain metastases, and no need for steroid treatment for at least 14 days prior to the first administration of the study intervention, they may participate in the study.
Patients with active systemic autoimmune diseases requiring systemic treatment (i.e., using immunomodulators, corticosteroids, or immunosuppressants). Replacement therapies (such as thyroxine, insulin, or physiological corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) are not considered systemic treatment.
