A Prospective, Single-Arm, Phase II Clinical Study of Neoadjuvant Therapy With Pucotenlimab, Lenvatinib, and Temozolomide for Resectable Head and Neck Mucosal Melanoma (PLT-NAT-HNMM-II)

This study aims to conduct a prospective clinical trial investigating the use of pucotenlimab in combination with lenvatinib and temozolomide as neoadjuvant and postoperative adjuvant therapy for resectable oral and head and neck mucosal melanoma. The primary objectives are to evaluate the safety and efficacy of this combination regimen in the neoadjuvant treatment of head and neck mucosal melanoma.

Inclusion: Age 18 to 75 years, regardless of gender; Histologically confirmed primary, resectable Head and Neck Mucosal Melanoma (HNMM), with measurable lesions (spiral CT scan ≥10 mm, meeting RECIST 1.1 criteria) or intraoral patch lesions deemed evaluable by the study investigators; ECOG performance status of 0 or 1; Life expectancy ≥12 weeks; At least one measurable lesion according to RECIST 1.1 criteria. Previously treated lesions can also serve as target lesions if disease progression has occurred; Availability of tumor tissue for PD-L1 testing (paraffin-embedded specimens from within the last 2 years or fresh tumor tissue); Organ function must meet the following requirements (within 14 days prior to the first dose of the study drug):; **Bone Marrow:** Absolute neutrophil count (ANC) ≥1.5 × 10⁹/L, platelet count (PLT) ≥100 × 10⁹/L, hemoglobin (HB) ≥9 g/dL (no blood transfusion or blood product administration within 14 days prior to testing); **Liver:** Serum total bilirubin (TBIL) ≤1.5 × upper limit of normal (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 × ULN (if liver metastases are present, AST and ALT ≤5 × ULN are permitted); **Kidneys:** Serum creatinine ≤1.5 × ULN or creatinine clearance ≥60 mL/min, blood urea nitrogen ≤200 mg/L; Thyroid-stimulating hormone (TSH) ≤1 × ULN (if abnormal, free T3 [FT3] and free T4 [FT4] levels should also be assessed; if FT3 and FT4 levels are normal, the patient may be enrolled); Urine protein ≤1+; if urine protein >1+, a 24-hour urine protein collection is required, and the total amount must be ≤1 gram; Normal cardiac function, defined as an electrocardiogram (ECG) without clinically significant abnormalities and a left ventricular ejection fraction (LVEF) >50% as shown by echocardiography; Female subjects of childbearing potential must have a negative serum pregnancy test result prior to the first dose of the investigational drug; Male or female subjects of childbearing potential must use highly effective contraception methods (e.g., oral contraceptives, intrauterine devices, sexual abstinence, or barrier methods combined with spermicide) throughout the entire trial period and continue contraception for 90 days after the end of treatment; Subjects must voluntarily join the study, sign an informed consent form, demonstrate good compliance, and cooperate with follow-up.

Exclusion: Prior treatment with PD-1/PD-L1/PD-L2/CTLA-4 antibodies, or drugs targeting T-cell receptor activation or inhibition (e.g., OX40, CD137); Primary lesion cannot be completely resected; presence of distant metastases; or local lesions are not indicated for surgery; Concurrently receiving any other anti-tumor therapy; Presence of any uncontrolled clinical condition, including but not limited to:; Persistent or active (severe) infection; Poorly controlled diabetes; Cardiac disease (NYHA Class III/IV congestive heart failure or heart block); Current or suspected autoimmune disease, or history of autoimmune disease or syndromes requiring systemic steroid/immunosuppressant therapy, such as hypophysitis, colitis, hepatitis, nephritis, hyperthyroidism, hypothyroidism, etc; Occurrence of any of the following within 6 months prior to the first dose: deep vein thrombosis or pulmonary embolism; myocardial infarction; severe or unstable arrhythmia or angina; percutaneous coronary intervention, acute coronary syndrome, or coronary artery bypass graft; cerebrovascular accident, transient ischemic attack, or cerebral embolism; Occurrence of any of the following within 6 months prior to the first dose: deep vein thrombosis or pulmonary embolism; myocardial infarction; severe or unstable arrhythmia or angina; percutaneous coronary intervention, acute coronary syndrome, or coronary artery bypass graft; cerebrovascular accident, transient ischemic attack, or cerebral embolism; Concurrent participation in other clinical studies, except for observational studies or those deemed non-conflicting with this study; Patients using immunosuppressants or systemic corticosteroids for immunosuppressive purposes (equivalent to >10mg/day prednisone) and continuing such use within 2 weeks prior to enrollment; Patients who have received hematopoietic growth factors (e.g., G-CSF, erythropoietin) within 1 week prior to the first dose of the study drug; Allergy to recombinant humanized anti-PD-1 monoclonal antibody or its components; Uncontrolled severe acute infection; Patients with active hepatitis B or C:; If HBsAg or HBcAb is positive, HBV DNA must be tested (excluded if above the upper limit of normal); If HCV antibody is positive, HCV RNA must be tested (excluded if above the upper limit of normal); History of stem cell or organ transplantation; History of psychoactive drug abuse with inability to abstain, or history of psychiatric disorders; Patients whom the investigator judges to have poor compliance or other conditions making them unsuitable for participation in this trial; History of other malignancies within the past 5 years, except for cured basal cell carcinoma, squamous cell carcinoma of the skin, early-stage prostate cancer, and carcinoma in situ of the cervix; Any underlying medical condition that, in the investigator's opinion, would increase the risk of study drug administration or confound the assessment of toxicity or adverse events; Any other severe, acute, or chronic medical condition or laboratory abnormality that, in the investigator's judgment, may increase study-related risk or potentially interfere with the interpretation of study results; Cutaneous melanoma, ocular melanoma, or melanoma of unknown primary origin; Pregnancy, lactation, or women of childbearing potential not using contraception.
