Official title

Study of the OPTtimum Duration of Acoustic Pulse ThromboLYSis ProcEdure in the Treatment of Acute Submassive Pulmonary Embolism

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective is to determine the optimum dose of thrombolytic and duration of the ultrasound procedure (together defined as the APT Procedure) as a treatment for acute submassive pulmonary embolism (PE). Symptomatic submassive PE are participants with acute (less than or equal to \[≤\]14 days) PE with normal systemic arterial blood pressure (greater than \[\>\] 90 mmHg) and evidence of RV dysfunction (right ventricular to left ventricular diameter ratio, that is; RV/LV ratio greater than or equal to \[≥\] 0.9). Participants with submassive PE will be randomized to one of four APT treatment groups: ultrasound of 2 and 6 hours (hrs) with r-tPA 2 milligrams (mg)/hr/catheter and ultrasound 4 and 6 hours with r-tPA, 1 mg/hr/catheter. On 08 June 2016, randomization into treatment group 4 (APT/6 hours-r-tPA/2 mg/hr/catheter) was closed following a reported intracranial hemorrhage (ICH) and death in a study participant in this arm.
