Study to Evaluate the Safety and Efficacy of Serplulimab Plus Bevacizumab and Chemotherapy in NSCLC Patients With Brain Metastases

Korábbi kezelés

• Any active infection requiring systemic anti-infective therapy occurs within 14 days prior to initial administration;
• Subjects with prior or screening history of interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, and severe impairment of lung function, which the investigators judged might interfere with the detection and management of suspected drug-related pulmonary toxicity;
• Those who received live or attenuated vaccines within 28 days prior to the first dose or have plans to receive such vaccines during the study period; But inactivated virus vaccines for seasonal influenza are allowed.

Más betegség

• A known history of severe allergy to any monoclonal antibody (NCI-CTCAE 5.0 grade greater than 3); Or known hypersensitivity to carboplatin/pemetrexed components;
• Hepatitis B patients [hepatitis B surface antigen (HBsAg) positive and detection of HBV-DNA suggests viral replication]; Or hepatitis C patients [hepatitis C virus (HCV) antibody positive and HCV-RNA test indicates viral replication]; Or syphilis screening positive (specific antibody test positive, non-specific antibody test negative and combined with clinical diagnosis confirmed as non-active infection); Or a known human immunodeficiency virus (HIV) positive history or HIV screening positive;
• Subjects have known active or suspected autoimmune diseases. Subjects in stable state who did not require systemic immunosuppressive therapy were admitted;
• Other active malignancies within 5 years or at the same time. Localized tumors that have been cured for more than 5 years, such as skin basal cell carcinoma, skin squamous cell carcinoma, superficial bladder carcinoma, prostate carcinoma in situ, cervical carcinoma in situ and breast carcinoma in situ, can be included in the group.

Laborértékek

• A history of myocardial infarction and poorly controlled arrhythmias (including QTc interval ≥450 ms in men and 470 ms in women) within 6 months prior to initial administration (QTc interval calculated by Fridericia formula); Or left ventricular ejection fraction according to NYHA standard for Grade III-IV cardiac insufficiency or color Doppler ultrasound \< 50%;
• The subject has uncontrolled or symptomatic hypercalcemia (\> 1.5 mmol/L ionic calcium or calcium \> 12 mg/dL or corrected serum calcium \> ULN);

Egyéb

• The subjects had ≥ grade 2 CTCAE peripheral neuropathy;

• Subjects with stage IV non-squamous non-small cell lung cancer (nsqNSCLC) with brain metastases confirmed by histopathology or cytology;
• The patient should provide a gene test report within 3 months, and the gene report showed negative driver gene, that is, no EFGR sensitive gene mutation, no ALK or ROS1 gene fusion;
• MRI confirmed brain parenchymal metastasis with ≥3 brain lesions; Or have 1-2 brain lesions but not suitable for local treatment or refuse local treatment patients. There must be at least 1 measurable lesion with a diameter ≥5mm in the brain; Patients with local meningeal metastases were allowed, but patients with extensive meningeal metastases were not included;
• For asymptomatic BMS or BMS whose intracranial hypertension symptoms were controlled after dehydration treatment, medication could be continued at the time of enrollment or during the study period to keep symptoms stable;
• There was at least one measurable target lesion as assessed by RECIST v1.1 within 4 weeks prior to initial medication;
• The patient agrees to provide the genetic test results within 3 months; if not, the patient shall provide the tumor tissue that meets the requirements for genetic test;
• ECOG PS score is 0-1; Good functioning of vital organs
