PRINCETON, N.J., Nov. 14, 2022  /PRNewswire/ — CytoSorbents Corporation (NASDAQ: CTSO), a leader in the treatment of life-threatening conditions in the intensive care unit and cardiac surgery using blood purification via its proprietary polymer adsorption technology, announced that 40 of the targeted 120 patients have been enrolled in the Safe and Timely Antithrombotic Removal – Ticagrelor (STAR-T) trial, achieving the first enrollment milestone and triggering a pre-specified Data and Safety Monitoring Board (DSMB) review.  This pivotal study intends to support both U.S. FDA and Health Canada marketing approval of DrugSorb-ATR in the United States and Canada, respectively, to remove the anti-thrombotic agent, ticagrelor (Brilinta®, AstraZeneca), during cardiothoracic surgery. 

CytoSorbents’ pivotal STAR-T trial using DrugSorb-ATR to remove ticagrelor during cardiac surgery now a third complete

Dr. Michael J. Mack, Director of the Cardiovascular Service line at Baylor Scott & White Health System, Chairman of the Baylor Plano Research Center in Texas and co-Principal Investigator of the STAR-T trial commented: “Reaching our first trial enrollment milestone of 40 patients is a critical first step in the execution of the landmark STAR-T trial. Currently, cardiac surgeons are either forced to delay life-saving heart surgery in patients who are on antithrombotic drugs or proceed to operation when they are at very high risk for bleeding. The DrugSorb-ATR device is a novel approach that could potentially allow these high-risk surgeries to proceed in a safe and timely manner. We have designed two rigorous, pivotal trials to test the efficacy and safety of this novel device that if successful could make it available to all U.S. cardiac surgeons, so they can join their international colleagues who have it available and use it routinely in their everyday practice. We are currently focused on bringing the STAR-T trial across the finish line, so we can then turn our attention to STAR-D. I’d like to thank all of the participating centers and investigators for helping us reach this first crucial enrollment milestone and we remain very excited to welcome our Canadian colleagues who should begin contributing to enrollment very soon.”

Dr. Efthymios N. Deliargyris, Chief Medical Officer of CytoSorbents stated, “We are pleased to have enrolled a third of our STAR-T pivotal study, which now triggers the first safety review by the independent DSMB of the study.  We are now working diligently to complete the necessary operational steps including data collection and validation to support the upcoming DSMB safety review which is estimated in approximately 2 months.  With our full attention and resources now dedicated to STAR-T and the upcoming addition of Canadian sites, we anticipate the momentum to continue and project that we can achieve the next study milestone of 80 patients enrolled in Spring 2023 that will trigger the next DSMB safety review and the pre-specified interim analysis.

About CytoSorbents Corporation (NASDAQ: CTSO)

CytoSorbents Corporation is a leader in the treatment of life-threatening conditions in the intensive care unit and in cardiac surgery through blood purification.  Its lead product, CytoSorb®, is approved in the European Union and distributed in 75 countries worldwide. It is an extracorporeal cytokine adsorber that reduces “cytokine storm” or “cytokine release syndrome” in common critical illnesses that can lead to massive inflammation, organ failure and patient death.  In these diseases, the risk of death can be extremely high, and there are few, if any, effective treatments.  CytoSorb is also used during and after cardiothoracic surgery to remove inflammatory mediators that can lead to postoperative complications, including multiple organ failure.  As of September 30, 2022, more than 186,000 CytoSorb devices have been used cumulatively.  CytoSorb was originally launched in the European Union under CE mark as the first cytokine adsorber.  Additional CE mark extensions were granted for bilirubin and myoglobin removal in clinical conditions such as liver disease and trauma, respectively, and for ticagrelor and rivaroxaban removal in cardiothoracic surgery procedures.  CytoSorb has also received FDA Emergency Use Authorization in the United States for use in adult critically ill COVID-19 patients with impending or confirmed respiratory failure.  The DrugSorb™-ATR antithrombotic removal system, based on the same polymer technology as CytoSorb, also received two FDA Breakthrough Device Designations, one for the removal of ticagrelor and another for the removal of the direct oral anticoagulants (DOAC) apixaban and rivaroxaban in a cardiopulmonary bypass circuit during urgent cardiothoracic procedures.  The Company is currently conducting the FDA-approved, randomized, controlled STAR-T (Safe and Timely Antithrombotic Removal-Ticagrelor) study of 120 patients at 30 centers to evaluate whether intraoperative use of DrugSorb-ATR can reduce the perioperative risk of bleeding in patients receiving ticagrelor and undergoing cardiothoracic surgery.  This pivotal study intends to support both U.S. FDA and Health Canada marketing approval of DrugSorb-ATR in the United States and Canada, respectively, for this application.  The STAR-T trial will be followed by the STAR‑D (Safe and Timely Antithrombotic Removal-Direct Oral Anticoagulants) pivotal trial evaluating the intraoperative use of DrugSorb-ATR to reduce perioperative bleeding risk in patients undergoing cardiothoracic surgery and taking direct oral anticoagulants, including apixaban and rivaroxaban.

CytoSorbents’ purification technologies are based on biocompatible, highly porous polymer beads that can actively remove toxic substances from blood and other bodily fluids by pore capture and surface adsorption.  Its technologies have received non-dilutive grant, contract, and other funding of approximately $48 million from DARPA, the U.S. Department of Health and Human Services (HHS), the National Institutes of Health (NIH), National Heart, Lung, and Blood Institute (NHLBI), the U.S. Army, the U.S. Air Force, U.S. Special Operations Command (SOCOM), Air Force Material Command (USAF/AFMC), and others.  The Company has numerous marketed products and products under development based upon this unique blood purification technology protected by many issued U.S. and international patents and registered trademarks, and multiple patent applications pending, including ECOS-300CY®, CytoSorb-XL™, HemoDefend-RBC™, HemoDefend-BGA™, VetResQ®, K+ontrol™, DrugSorb™, DrugSorb™-ATR, ContrastSorb, and others.  For more information, please visit the Company’s websites at and or follow us on Facebook and Twitter
