Study summary

The purpose of this multicenter study is to assess the impact of SSO2 treatment on clinical outcomes and left ventricular function in patients following acute ST-segment elevation myocardial infarction (STEMI).

Read the detailed description

The TherOx® Downstream® System, which is approved for use in the United States (US) by the Food and Drug Administration (FDA) under P170027. The TherOx® Downstream® System consists of three primary components. These include a hardware device called the TherOx Downstream System ("console"), a single-use disposable device called the TherOx Downstream Cartridge ("cartridge") and a 5 French, commercially available qualified SSO2 infusion coronary delivery catheter ("delivery catheter").

This is a multicenter, retrospective case-control study which will collect data from all STEMI patients who received SSO2 treatment at participating centers, along with up to 3 matched control patients who did not receive SSO2 treatment.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 4, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
