TherOx, Inc., a privately held medical device company focused on improved treatment of Acute Myocardial Infarction (AMI), announced that it completed enrollment in the IC-HOT (Evaluation of IntracoronaryHyperoxemic Oxygen Therapy) study. IC-HOT is a confirmatory study of the second-generation TherOx system that delivers Supersaturated Oxygen (SSO2) Therapy for reduction of infarct size after an AMI.
The IC-HOT study enrolled 100 patients and is being conducted to support a PreMarket Approval submission to the U.S. Food and Drug Administration (FDA). The primary study objective is to collect confirmatory data supporting the safety and effectiveness of SSO2Therapy in treatment of anterior AMI patients who have undergone successful percutaneous coronary intervention (PCI) with stenting within six hours of experiencing AMI symptoms.
“Since the advent of angioplasty and stenting to treat heart attack we haven’t seen any new treatment options to reduce infarct size in this vulnerable population, and SSO2 Therapy appears to fulfill this unmet need,” said Nainesh Patel, MD, interventional cardiologist at Lehigh Valley Health Network and an investigator for the study.
According to the American Heart Association, every year nearly one million people in the U.S. have heart attacks. Although PCI is the standard of care in treating AMI, for many patients it doesn’t do enough to reduce infarct size and achieve maximum clinical benefit.
“SSO2 Therapy treats patients who have experienced the most serious large anterior wall heart attacks – patients who often have poor outcomes even after successful intervention,” said Frances Wood, MD, interventional cardiologist at WakeMed Heart and Vascular – Structural Heart and study investigator. “This therapy is a promising new tool to reduce infarct size and thus improve outcomes for these higher risk patients.”
SSO2 Therapy is intended to provide interventional cardiologists with the first treatment option beyond PCI to salvage heart muscle in heart attack patients. In SSO2 Therapy, the patient’s blood is supersaturated with oxygen and then returned directly to the targeted ischemic area of the heart through a small catheter. Adjunctive to PCI, SSO2 Therapy is intended to salvage the jeopardized myocardium and thus reduce infarct size. Multiple peer-reviewed studies have demonstrated the infarct size reduction achieved by SSO2 Therapy was clinically significant compared to PCI alone.
“Completing enrollment in our IC-HOT study significantly advances us closer to our goal of improving treatment options in the U.S. for physicians and their heart attack patients,” said Kevin T. Larkin, president and chief executive officer of TherOx.
