Disitamab Vedotin in Combination with Tislelizumab and Bevacizumab in a Phase II Clinical Study of Locally Advanced or Metastatic Non-small Cell Lung Cancer with HER2 Mutation/amplification/expression

Recruiting now · Phase 2

Conditions studied: Lung Cancer

In brief

The goal of this clinical trial is to learn ifDisitamab Vedotin in combination with tislelizumab and bevacizumab can treat in locally advanced or metastatic non-small cell lung cancer patients with HER2 mutation/amplification/expression. The main questions it aims to answer are: 1. objective response rate; 2. Progression-Free Survival; 3. Overall Survival; 4. Disease Control Rate; 5. Duration of Response.

You may qualify if…

• Prior to the implementation of any trial-related procedures, written informed consent must be obtained;
• Aged >= 18 years;
• Patients with locally advanced (Stage III B/III C), metastatic, or recurrent (Stage IV) non-small cell lung cancer (NSCLC) confirmed histologically or cytologically, who are ineligible for surgical intervention and cannot undergo curative radiochemotherapy, as per the 8th edition TNM staging classification of the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer;
• Provision of archived tumor tissue or tissue obtained during screening biopsy for biomarker testing, including PD-L1 expression, HER2 mutation status, etc.;
• HER2 mutation, amplification, or HER2 expression (IHC 1+, 2+, or 3+);
• Investigator confirmation of at least one measurable lesion according to RECIST 1.1 criteria;
• Cohort I: Patients who have received prior ≥1 line of systemic therapy or HER2 tyrosine kinase inhibitors such as afatinib, pyrotinib, or pozitinib. Cohort II: No prior receipt of any systemic anti-tumor therapy for advanced/metastatic disease; For patients who have previously received platinum-containing adjuvant/radiotherapy, neoadjuvant/radiotherapy, or radical chemoradiotherapy for advanced disease, disease progression occurs >6 months after the end of the last treatment, may participate in this study;
• Expected life expectancy >= 3 months;
• ECOG PS 0-1;
• Adequate hematologic function, defined as an absolute neutrophil count >= 1.5×10\^9/L, platelet count >= 100×10\^9/L, hemoglobin >= 90g/L (without a history of blood transfusion in the past 7 days);
• Adequate liver function, defined as total bilirubin level <= 1.5 times the upper limit of normal (ULN) and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels <= 2.5 times ULN for all patients, or for patients with liver metastasis, AST and ALT levels <= 5 times ULN;
• Adequate renal function, defined as serum creatinine <= 1.5 times ULN;
• Adequate coagulation function, defined as international normalized ratio (INR) or prothrombin time (PT) <= 1.5 times ULN; if a subject is on anticoagulant therapy, INR/PT should be within the therapeutic range set by the anticoagulant;
• Women of childbearing potential must undergo a pregnancy test within 7 days prior to the start of treatment, with negative results; and reliable contraception methods (such as intrauterine devices, oral contraceptives, and condoms) should be used during the trial and for 30 days after the end of the trial. Men of childbearing potential should use condoms for contraception during the trial and for 30 days after the end of the trial;
• Willingness to comply with regular follow-up visits and adhere to trial requirements.

You may not qualify if…

• Currently participating in interventional clinical research treatment;
• Prior treatment with HER2 antibodies or antibody-drug conjugates;
• Received traditional Chinese medicine or immunomodulatory drugs (such as thymopeptides, interferons, interleukins, etc.) with anti-tumor indications within the 2 weeks preceding the first dose;
• Patients undergoing EGFR-TKI treatment require a 2-week washout period;
• History of allergic reactions to any components of the investigational drug;
• Presence of clinically significant active hemoptysis, active diverticulitis, intra-abdominal abscess, gastrointestinal obstruction, or peritoneal metastasis requiring clinical intervention;
• Presence of clinically uncontrollable pleural effusion/ascites (patients not requiring drainage or with no significant increase in effusion for 3 days may be eligible);
• Tumor compression of vital surrounding organs (such as the esophagus) accompanied by relevant symptoms, compression of the superior vena cava, or invasion of major mediastinal vessels, heart, etc.;
• Severe complications such as a history of severe pulmonary or cardiac diseases; occurrence of any arterial thrombosis, embolism, or ischemia within 6 months prior to enrollment, including myocardial infarction, unstable angina, cerebrovascular accident, or transient ischemic attack. A history of deep vein thrombosis, pulmonary embolism, or any other serious thromboembolic event within the past 3 months before enrollment;
• Known presence of brain metastases. Asymptomatic or stable patients with brain metastases, as judged by the investigator, may be eligible;
• Received systemic corticosteroids (>10 mg/day prednisone or equivalent) or other systemic immunosuppressive agents (including but not limited to prednisone, dexamethasone, cyclophosphamide, azathioprine, mercaptopurine, methotrexate, thalidomide, and anti-tumor necrosis factor [anti-TNF] agents) within the 2 weeks prior to enrollment. Local, ocular, intra-articular, intranasal, and inhaled corticosteroids are allowed;
• History of autoimmune diseases, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vasculitis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis. Patients with autoimmune-related hypothyroidism receiving stable doses of thyroid hormone replacement therapy are eligible. Patients with controlled type 1 diabetes on stable insulin regimens are eligible;
• Active systemic infections, including tuberculosis (clinically diagnosed based on medical history, physical examination, imaging findings, and routine TB examinations), hepatitis B (known positive for hepatitis B surface antigen [HBsAg] with HBV DNA >= 1000 cps/ml or its reference lower limit), hepatitis C, or human immunodeficiency virus (HIV antibody positive);
