Phase II Exploratory Study of Sequential Triple Therapy (Temozolomide/Anlotinib/Bemarituzumab) in Combination With Concurrent Radiotherapy With Temozolomide and Anlotinib for the Maintenance Treatment of Diffuse Midline Gliomas in Children

Plain-language summary
This study is a phase II single center exploratory clinical trial aimed at evaluating the efficacy and safety of temozolomide combined with anlotinib synchronous radiotherapy sequential triple therapy (temozolomide/anlotinib/PD-L1 inhibitor) for the maintenance treatment of diffuse midline gliomas (DMG) in children. The research plan includes 33 children with DMG aged 3-18 years, who have been pathologically diagnosed and have not received systematic treatment. The implementation will be divided into two stages: synchronous radiotherapy and chemotherapy stage (54Gy radiotherapy+oral temozolomide 75mg/m ²+sequential oral anlotinib) and maintenance treatment stage (increasing temozolomide dose+continuous use of anlotinib+intravenous injection of PD-L1 inhibitor according to body weight). Through multi mechanism synergy (radiotherapy sensitization, anti angiogenesis, and immune activation), the limitations of traditional treatment will be overcome. The primary endpoint is progression free survival (PFS), while secondary endpoints include objective response rate (ORR), 2-year overall survival rate (2y OS), quality of life, and safety (CTCAE 4.0 criteria). The innovation of the research lies in the first proposal of a "synchronous maintenance" staged mode, targeting the molecular characteristics of DMG (H3K27M mutation), combined with previous evidence at home and abroad (such as the median PFS of 10.2 months for anlotinib combined with synchronous radiotherapy), aiming to provide a new comprehensive treatment plan for this highly invasive tumor.

. Previously received anti-tumor treatment for diffuse midline glioma;
✕. Previous or concurrent malignant tumors (excluding malignant tumors that have been cured and have a cancer free survival of more than 5 years, such as basal cell carcinoma of the skin, cervical carcinoma in situ, and papillary thyroid carcinoma);
✕. Uncontrolled clinical symptoms or diseases of the heart, such as: (1) NYHA grade II or above heart failure (2) unstable angina pectoris (3) myocardial infarction within 1 year (4) clinically significant supraventricular or ventricular arrhythmias requiring clinical intervention in patients;
✕. Active infections that require treatment;
✕. People with congenital or acquired immune deficiency (such as HIV infected people), active hepatitis B (HBV-DNA ≥ 104 copies/ml or 2000IU/ml) or hepatitis C (hepatitis C antibody is positive, and HCV-RNA is higher than the detection limit of the analytical method);
✕. Known history of substance abuse, alcoholism, or drug use;
✕. According to the researcher's judgment, there may be other factors that could force the subject to terminate the study midway, such as suffering from other serious illnesses (including mental illnesses) that require concurrent treatment, severe abnormal laboratory test values, family or social factors that may affect the subject's safety or the collection of trial data;
✕. Patients who the surgeon believes can undergo curative resection;
