CytoSorbents Receives Recommendation from Independent Data and Safety Monitoring Board to Continue Pivotal STAR-T Trial As Planned Without Modifications
PRINCETON, N.J., December 21, 2022 — 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 it has received the recommendation from the independent Data and Safety Monitoring Board (DSMB) to continue the pivotal Safe and Timely Antithrombotic Removal – Ticagrelor (STAR-T) trial as planned without any modifications.
Dr. Efthymios N. Deliargyris, Chief Medical Officer of CytoSorbents commented, “The independent DSMB has completed the review of the full unblinded dataset from the first 40 patients enrolled in the STAR-T trial and we are very pleased to receive the recommendation to continue the study as planned without any modifications. All our clinical resources continue to focus on enrollment with the goal of achieving the next milestone of 80 patients enrolled by Spring 2023, triggering another safety review and the execution of the trial’s prespecified interim analysis by the independent DSMB.”
The STAR-T randomized, controlled trial is a 120-patient, 30 center pivotal study designed to evaluate the ability of DrugSorb-ATR® to reduce perioperative bleeding by removing the antithrombotic agent, ticagrelor (Brilinta®, AstraZeneca) in patients undergoing cardiothoracic surgery. Brilinta is one of the leading “blood thinners” used as part of dual-antiplatelet therapy in patients suspected of having a heart attack. But if the patient is one of the up to 10% that need to undergo coronary artery bypass graft (CABG) or other open heart surgery, the risk of major fatal or life-threatening CABG-related bleeding can be as high as 50-65%, particularly if the surgery is performed within several days of the last Brilinta dose. Waiting in the hospital to wash out the drug is the only acceptable alternative, but this comes at high cost and potential clinical risk. The goal of DrugSorb-ATR is to allow patients to get the critical surgery they need without delay, while reducing or preventing this bleeding risk by actively removing the drug during the surgery. DrugSorb-ATR has received FDA Breakthrough Device Designation for this indication. The STAR-T pivotal study is being conducted by many of the leading cardiothoracic surgery centers in North America and is intended to support U.S. FDA and Health Canada marketing approval for DrugSorb-ATR in this application.
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 more than 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 label expansions were received for the removal of bilirubin and myoglobin in clinical conditions such as liver disease and trauma, respectively, and both ticagrelor and rivaroxaban during cardiothoracic surgery. CytoSorb has also received FDA Emergency Use Authorization in the United States for use in adult critically ill COVID-19 patients with imminent 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 approximately 30 centers in U.S. and Canada 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 is intended to support FDA marketing approval in the United States and Health Canada marketing approval for DrugSorb-ATR in this application.
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.
