Intermediate high-risk pulmonary embolism (PE) is characterised by right ventricular (RV) dysfunction and elevated circulating cardiac troponin levels despite apparent haemodynamic stability at presentation. In these patients, full-dose systemic thrombolysis reduced the risk of haemodynamic decompensation or death but increased the risk of life-threatening bleeding. Reduced-dose thrombolysis may be capable of improving safety while maintaining reperfusion efficacy. The Pulmonary Embolism International Trial (PEITHO)-3 study (EudraCT 2018-000816-96) is a randomised, placebo-controlled, double-blind, multicentre, multinational trial with long-term follow-up. We will compare the efficacy and safety of a reduced-dose alteplase regimen with standard heparin anticoagulation. Patients with intermediate high-risk PE will also fulfil at least one clinical criterion of severity: systolic blood pressure ≤ 110 mmHg, respiratory rate >20 breaths/min, or history of heart failure. The primary efficacy outcome is the composite of all-cause death, haemodynamic decompensation or PE recurrence within 30 days of randomisation. Key secondary outcomes, to be included in hierarchical analysis, are fatal or GUSTO severe or life-threatening bleeding; net clinical benefit (primary efficacy outcome plus severe or life-threatening bleeding); and all-cause death, all within 30 days. All outcomes will be adjudicated by an independent committee. Further outcomes include PE-related death, haemodynamic decompensation, or stroke within 30 days; dyspnoea, functional limitation or RV dysfunction at 6 months and 2 years; and utilisation of healthcare resources within 30 days and 2 years. The study is planned to enrol 650 patients. The results are expected to have a major impact on risk-adjusted treatment of acute PE and inform guideline recommendations.
