  2. Rationale: risk-adjusted treatment of acute PE Thrombolysis?

  3. PEITHO: Objectives Primary To investigate the clinical benefits (efficacy) of thrombolysis with tenecteplase* over placebo in normotensive patients with acute intermediate-risk PE (both treatment arms receive standard heparin anticoagulation) Secondary To assess the safety of tenecteplase* in patients with intermediate-risk PE * Tenecteplase is not approved medication for use in pulmonary embolism in the United States or Europe.

  4. PEITHO: Primary outcome • All-cause mortality or • Hemodynamic collapse within 7 days of randomization, defined as: need for cardiopulmonary resuscitation or systolic BP < 90 mm Hg for ≥15 min or drop by ≥ 40 mm Hg for ≥15 min with end organ hypoperfusion (cold extremities, urinary output < 30 mL/h, mental confusion) or need for catecholamines to maintain adequate organ perfusion and a systolic BP of >90 mm Hg

  5. PEITHO: Secondary efficacy and safety outcomes Secondary end points : • All-cause mortality within 7 days of randomization • Hemodynamic collapse within 7 days of randomization • Confirmed symptomatic pulmonary embolism recurrence within 7 days • All-cause mortality within 30 days of randomization Safety endpoints • Non-intracranial major bleeding within 7 days • Total strokes (intracranial hemorrhage or ischemic stroke) within 7 days • Serious adverse events (SAE) within 30 days All end points were adjudicated by an independent 3-member Clinical Events Committee (CEC)

  19. PEITHO: Conclusions  In patients with intermediate-risk pulmonary embolism, intravenous bolus tenecteplase significantly reduced the primary end point of death or hemodynamic collapse within 7 days of randomization.  The results of PEITHO justify the concept of risk stratification of normotensive patients with acute PE.  They confirm the notion that early “advanced” (recanalization) treatment prevents clinical deterioration in patients with evidence of right ventricular dysfunction and myocardial injury.  In PEITHO, the benefits of thrombolysis came at the cost of a significantly increased risk of major, particularly intracranial, hemorrhage.  The patient’s age should be taken into account when weighing the expected benefits versus risks of systemic thrombolysis in clinical practice.
