简要总结
The Oris trial aims to evaluate whether the use of Ongericimab injection in patients with atherosclerotic ischemic cerebrovascular disease within 3 months of onset can reduce the risk of recurrent major cardiovascular events by achieving lower lipid-lowering target values (LDL-C < 1.4 mmol/L).

入选标准
- •Obtaining informed consent;
- •Age ≥18 years;
- •Patients with ischemic stroke within 3 months( NIHSS<15 before randomization);
- •Presence of ≥50% stenosis in major intracranial or extracranial arteries, and related to the symptoms of the current episode or the location of infarction;
- •LDL-C ≥ 70 mg/dL (1.8 mmol/L) at screening.
排除标准
- •History of cerebral hemorrhage at any time (microhemorrhages present only on SWI are not an exclusion criterion)
- •Hemorrhage or other pathological neurological conditions on baseline brain CT/MRI (e.g., vascular malformations, tumors, abscesses, or common non-ischemic brain diseases like multiple sclerosis);
- •Presence of isolated sensory symptoms (e.g., numbness), isolated visual changes, or isolated dizziness or vertigo, but no evidence of recent infarction on baseline head CT or MRI;
- •Unable to complete the assessment of intracranial and extracranial arterial stenosis before randomization
- •mRS score≥2 before onset (based on assessment of medical history);
- •Stroke caused by angioplasty/vascular surgery;
- •Cardioembolic stroke caused by atrial fibrillation, artificial heart valves, endocarditis, mitral stenosis, sinus node dysfunction, etc.
- •Most recent fasting triglycerides >400 mg/dL (4.5 mmol/L) prior to randomization;
- •Uncontrolled hypertension (SBP >180 mmHg or DBP >110 mmHg);
- •Hypothyroidism diagnosed within 1 month before randomization.
- •Severe renal impairment (eGFR <30 mL/min/1.73m²);
- •Active liver disease or dysfunction (AST/ALT >3×ULN within 30 days pre-randomization);
- •NYHA Class III/IV heart failure within 1 year prior to randomization;
- •Life-limiting non-cardiovascular diseases (life expectancy <1 years);
- •Malignancy within 10 years (excluding adequately treated basal cell carcinoma, cervical CIS, DCIS, or stage 1 prostate cancer);
- •Known hypersensitivity to monoclonal antibody therapies;
- •PCSK9 inhibitor use within 3 months before randomization.
- •Participation in other drug/device trials within 30 days;
- •Women of childbearing potential without contraception, pregnancy, or lactation;
- •Inability to understand or comply with the study due to mental illness, cognitive, or emotional disorders, or other reasons deemed unsuitable for participation in the study by the investigator.
研究组 & 干预措施
Control group (High target group)
Standardized lipid-lowering therapy according to the Chinese Stroke Association Guidelines for Clinical Management of Cerebrovascular Diseases to achieve an LDL-C target below 70 mg/dL (1.8 mmol/L).
干预措施: High target group (Combination Product)
Intervention group (Low target group)
Ongericimab subcutaneous injection once every two weeks (150mg) or every four weeks(300mg) combined with standardized lipid-lowering therapy to achieve an LDL-C target below 55 mg/dL (1.4 mmol/L)
干预措施: Low target group (Combination Product)
