HI-PEITHO Trial

 

 

The HI-PEITHO study has been designed to address a critical gap in clinical evidence in pulmonary embolism by comparing the clinical benefit of intervention with EKOS vs. the current standard of care – anticoagulation.

 

Trial Overview

Importance

This trial is the largest and first of its kind in pulmonary embolism (PE). It is designed to generate the most rigorous, highest level of data, contributing to the body of evidence for the treatment and outcomes in acute, intermediate-high risk PE. In addition, HI-PEITHO aims to advance the understanding of intermediate-high risk PE and risk stratification, to better identify patients who may clinically benefit from intervention, expanding access to care for these patients.

Summary

Mult-center Prospective Randomized Controlled Transatlantic menu
HI-PEITHO is a multi-center, prospective, randomised, controlled trial in the U.S. and Europe that will compare the outcomes of ultrasound-facilitated, catheter-directed, thrombolysis plus anticoagulation vs. anticoagulation alone for the treatment of acute, intermediate-high risk pulmonary embolism (PE).

Objective

EKOS™ Endovasular System + Anticoagulation vs. Anticoagulation Alone

Evaluate if treatment with EKOS is associated with a significant reduction in the acute composite outcome of the measures below compared to anticoagulation alone –​

  • PE-Related Death
  • Cardiorespiratory decompensation or collapse, and
  • Non-fatal symptomatic and objectively confirmed recurrence of PE 

 

Trial Methodology

Patients

  • Estimated enrollment: 406-544 participants​
  • Acute intermediate high-risk pulmonary embolism
  • ​RV/LV > 1.0, elevated troponin, & risk of early death/hemodynamic collapse​

End Points

7-day composite of –

  • PE-related mortality
  • PE recurrence (non-fatal symptomatic and objectively confirmed)
  • Cardiorespiratory decompensation or collapse

Cardiorespiratory decompensation or collapse, defined as at least one of the following:

  • Cardiac arrest or need for CPR​
  • Signs of shock: new onset arterial hypotension with end-organ hypoperfusion​
  • ECMO placement
  • ​Intubation or noninvasive mechanical ventilation​
  • National Early Warning Score (NEWS) of 9 or higher

Long Term Follow-Up

Additional follow-ups at 30-days, 6 months, and 1-Year

Reproduced from: Royal College of Physicians. National Early Warning Score (NEWS): Standardising the assessment of acute-illness severity in the NHS. Report of a working party. London: RCP, 2012

The NEWS is an early warning system score for clinical deterioration in hospitalised patients – it standardises the assessment of acute-illness severity.

The score aims to objectify how the patient is doing at the bedside.

The NEWS is based on an aggregate scoring system based on physiological measurements – respiration rate, oxygen saturations, supplemental oxygen need, temperature, systolic blood pressure, heart rate, and level of consciousness.
