Tunlametinib in Combination With Pucotenlimab and Hydroxychloroquine in NRAS Mutant Melanoma

Ki vehet részt

• Age ≥ 18 years of age, both genders
• Subjects with unresectable or metastatic melanoma (Stage III/IV) confirmed by histology or cytology
• The mutated NRAS genes were confirmed by sequencing
• Prior systemic antineoplastic therapy is allowed. All acute toxic effects of prior antitumor therapy must have resolved to grade 1 or lower before the start of the study drug, with the exception of alopecia (grade 1 or 2 permitted), neurotoxicity (grade 1 or 2 permitted), or bone marrow parameters (grade 1, 2, or 3 permitted)
• ECOG, 0-2
• The life expectance should be at least 12 months
• Eligible subjects had not received chemotherapy for locally advanced or metastatic disease and had at least one measurable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST 1.1 criteria)
• To ensure eligibility, the following criteria must be met regarding major organ and bone marrow functions: Adequate bone marrow function: absolute neutrophil count (ANC)≥ 1.5\^109/L, platelet count (PLT)≥ 100\^109/L, and hemoglobin level (HB)≥ 9 g/dL (no transfusion received within 14 days). Serum total bilirubin (TBIL) must be ≤ 1.5 times the upper limit of normal (ULN). Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 times the upper limits of normal, serum creatinine ≤1.5, and Creatinine clearance had to be greater than 50 mL/min. Creatinine clearance, as an estimate of glomerular filtration rate (eGFR), was calculated according to the Cockcroft and Gault (C\&G) equation (26): (140 - age [years] × weight [kg] × 0.85 for male)/ 72*serum creatinine (μmol/L). The International Normalized Ratio (INR) and activated partial thromboplastin time (aPTT) were a maximum of 1.5 fold the upper limit of normal (This provision applies only to Subjects not receiving anticoagulant therapy; for Subjects receiving anticoagulant therapy, anticoagulation should be within the therapeutic range.). Urine protein ≤ 1+; if urine protein > 1+, a 24-hour urine collection for protein quantification is required, and the total protein must be ≤ 1 g; FT3, FT4, and TSH levels should be normal, or any abnormalities should be clinically insignificant; lactate dehydrogenase (LDH) ≤ 2 × upper limit of normal (ULN)
• A urine pregnancy test must be negative within 7 days before enrollment for women of childbearing potential.Male and female Subjects of reproductive/childbearing potential must use highly effective contraception (e.g., oral contraceptives, IUDs, abstinence, or barrier plus spermicide) during the entire trial and for 12 months after treatment ends
• The subject voluntarily joins the study, has good compliance, and is cooperative with follow-up evaluations

• Subjects who have previously received anti-PD-1 antibody, anti-PD-L1/PD-L2 antibody therapy, and/or VEGFR TKI therapy
• Subjects currently receiving systemic anti-tumor therapy
• Subjects who have participated in or are currently participating in other drug/therapy clinical trials within 4 weeks prior to enrollment (calculated from the date of the last dose of the previous trial)
• Subjects who have undergone major surgery within 4 weeks prior to enrollment, or have not recovered from surgical side effects, or have received live vaccination within 4 weeks prior to enrollment
• Subjects who have received hematopoietic growth factors, such as granulocyte colony-stimulating factor (G-CSF), erythropoietin, etc., within 1 week prior to enrollment
• Subjects with active hepatitis B or hepatitis C who have not received antiviral therapy: if HBsAg or HBcAb is positive, HBVDNA should be tested (with results above the upper limit of normal range at the research center); if HCV antibody is positive, HCVRNA should be tested (with results above the upper limit of normal range at the research center)
• Subjects with a history of other invasive malignancy within the previous 5 years other than nonmelanoma skin cancer were excluded, except for curatively treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, early-stage prostate cancer, and cervical carcinoma in situ
• Subjects with positive test results for HIV antibody or Treponema pallidum antibody (based on test results from a Grade A tertiary hospital, including the study center)
• Subjects with known allergy to humanized anti-PD-1 monoclonal antibody drugs and their components; known allergy to MEK inhibitors (e.g., Tunlametinib) and any of their excipients; known allergy to autophagy inhibitors (e.g., hydroxychloroquine) and any of their excipients
