Smart combo attack: new trial matches lung cancer drugs to tumor fingerprints

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * The diagnosis of SCLC is confirmed by histology or cytology, and according to VALSG and AJCC9, the imaging diagnosis is extensive stage. * Patients who have not previously received systemic therapy for advanced or metastatic disease, or patients who have relapsed after concurrent chemo-radiotherapy during the localized stage. * The expected survival time is not less than 12 weeks. * According to RECIST V1.1, there is at least one measurable lesion that has not undergone radiation therapy. * The Eastern Cooperative Oncology Group (ECOG) physical condition score is evaluated as 0 or 1. * When screening, there is sufficient bone marrow reserve, and no blood transfusion or hematopoietic stimulating factor treatment has been received 10 days before the test. The definition is as follows: absolute neutrophil counts (ANC) ≥ 1.5×109/L, platelet (PLT) ≥ 100×109/L and hemoglobin (HGB) ≥ 90g/L. * Appropriate organ function during screening, meeting the following criteria: aspartate aminotransferase (AST) ≤ 2.5×ULN (with liver metastasis ≤ 5×ULN); alanine aminotransferase (ALT) ≤ 2.5ULN (with liver metastasis ≤ 5ULN); total serum bilirubin ≤ 1.5×ULN (with tumor infiltration ≤ 3×ULN); serum creatinine (Scr) ≤ 1.5×ULN, or creatinine clearance rate ≥ 60mL/min; international normalized ratio (INR) ≤ 1.5×ULN, and activated partial thromboplastin time (APTT) ≤ 1.5×ULN; the urine pregnancy test for women of childbearing age needs to be negative, and any male and female patients with fertility must agree to use effective contraceptive methods throughout the entire study process and for at least 1 year after treatment. Exclusion Criteria: * During screening, patients with symptomatic central nervous system (CNS) metastasis (asymptomatic CNS metastasis, or asymptomatic and stable condition after local treatment for 4 weeks can be enrolled). * Individuals with a history of central nervous system diseases before screening, such as epilepsy, cerebral ischemia/bleeding, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, mental illness, or any autoimmune disease associated with central nervous system involvement. * Received chemotherapy, radiation therapy, immunotherapy, targeted therapy, biological therapy, endocrine therapy within 4 weeks of screening, and was evaluated by the researcher as not suitable for enrollment. * The adverse reactions of previous anti-tumor treatments have not yet recovered to level 1 (CTCAE5.0), except for toxicity that the researchers have determined to have no safety risk, such as hair loss and level 2 peripheral neurotoxicity. * Those who discontinue systemic hormone therapy for less than 72 hours before the first administration, but are allowed to use physiological replacement doses of hormones (such as prednisone \< 10mg/d or equivalent). * Received organ/tissue transplantation before screening. * Prior to screening, it was known that the patient had active systemic autoimmune diseases and was currently undergoing treatment. * Those who meet any of the following conditions during screening: hepatitis B surface antigen (HBsAg) is positive, and the copy number of HBV DNA is greater than the measurable lower limit; hepatitis C antibody (HCV Ab) is positive; treponema pallidum antibody (TP-Ab) is positive; HIV antibody is positive; The copy numbers of EBV-DNA and CMV-DNA are higher than the measurable lower limit. * Individuals who have undergone major surgery or experienced significant trauma within 4 weeks prior to screening, or who require elective surgery during the trial period, have been evaluated by the researchers as unsuitable for inclusion. * Within 2 years prior to screening or currently suffering from other malignant tumors. * When screening, the heart meets any of the following conditions: New York Heart Association (NYHA) ≥ Level II, Left Ventricular Ejection Fraction (LVEF) ≤ 50% (ECHO); Hypertension (systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥ 90mmHg) or pulmonary hypertension that has not been controlled after standardized treatment; Acute coronary syndrome, congestive heart failure, aortic dissection, stroke, or other Grade 3 or higher cardiovascular and cerebrovascular events occurred within 6 months before the first administration; valvular disease with clinical significance; There are serious cardiac rhythm or conduction abnormalities, such as ventricular arrhythmias that require clinical intervention, II-III degree atrioventricular block, etc. * Patients with tumor involving the atrium or ventricle during screening. * When screening, there are clinical emergencies that require urgent treatment due to tumor obstruction or compression (such as intestinal obstruction or vascular compression). * Individuals with active bleeding during screening. * Those with a history of deep vein thrombosis or pulmonary embolism within 6 months before screening. * Individuals who have received live vaccines within 6 weeks before screening. * Subjects with uncontrolled systemic bacterial, viral, or fungal infections after optimal treatment. * Participated in other interventional clinical studies within 4 weeks before the first administration. * Individuals with poor adherence or those who are deemed unsuitable for clinical trials by researchers due to other reasons.
