Inclusion Criteria
- •Subjects (or their legal representatives/guardians) must sign the informed consent form, indicating that they understand the purpose of this study, are aware of the necessary procedures involved, and are willing to participate.
- •Aged ≥18 years and ≤75 years, regardless of gender.
- •Histologically or pathologically confirmed mucosal or acral melanoma.
- •Braf, Nras, and Ckit gene mutation status is unrestricted.
- •Unresectable or metastatic melanoma, having received ≤1 prior line of systemic therapy (disease recurrence or metastasis within 6 months after completion of adjuvant therapy is considered as first-line therapy).
- •Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0 to
- •Expected survival of more than 3 months.
- •At least one measurable lesion according to RECIST v1.
- •Note: Brain metastases cannot serve as target lesions; Lesions previously treated with radiotherapy cannot serve as target lesions unless imaging demonstrates clear progression.
- •Laboratory test results within 7 days prior to screening (including day 7) must meet the following criteria: Neutrophil count ≥1.5×10⁹/L; Platelet count ≥90×10⁹/L; Hemoglobin ≥90 g/L (without transfusion within 14 days); Serum total bilirubin ≤1.25 × upper limit of normal (ULN); ALT and AST ≤ 2.5 × ULN (≤5 × ULN for patients with liver metastases); Serum creatinine ≤1.25 × ULN.
Exclusion Criteria
- •History or presence of other malignancies within the past 5 years, except for cured localized tumors (e.g., basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, carcinoma in situ of the cervix, etc.).
- •Participation in treatment with an investigational drug or use of an investigational device within 4 weeks prior to the first dose of study treatment.
- •Palliative local therapy for non-target lesions within 2 weeks prior to the first dose; Non-specific immunomodulatory therapy (e.g., interleukins, interferons, thymosin, etc., excluding IL-11 used for treating thrombocytopenia) within 2 weeks prior to the first dose; Treatment with Chinese herbal medicine or Chinese patent medicine with anti-tumor indications within 1 week prior to the first dose.
- •Patients who have previously received iparomlimab and tuvoraleimab or other dual immunotherapy, bevacizumab, albumin-bound paclitaxel, or carboplatin.
- •Active autoimmune disease that has required systemic treatment in the past two years (i.e., with disease-modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement for adrenal or pituitary insufficiency) is not considered a form of systemic treatment.
- •History of active or documented inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis) or chronic diarrhea.
- •History of immunodeficiency; Positive HIV antibody test; Current long-term use of systemic corticosteroids or other immunosuppressive agents.
- •Known active tuberculosis (TB); Subjects suspected of having active TB must undergo clinical evaluation to rule it out; Known active syphilis infection.
- •History of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation.
- •History of non-infectious pneumonitis/interstitial lung disease that required systemic corticosteroid treatment or current presence of non-infectious pneumonitis.
