MONMOUTH JUNCTION, N.J., Sept. 5, 2017 /PRNewswire/ — CytoSorbents Corporation (NASDAQ: CTSO), a critical care immunotherapy leader commercializing its flagship CytoSorb® blood filter to prevent or treat deadly inflammation and organ failure in critically-ill and cardiac surgery patients around the world, announced the key results of three posters, accepted and presented last week in Orlando, Florida at the Military Health System Research Symposium (MHSRS), the premier U.S. scientific meeting focused on medical advances that address the unique medical needs of the warfighter.
- CytoSorb®: Traumatic Brain Injury (TBI) and Hemorrhagic Shock: Traumatic brain injury and severe blood loss leading to shock are two of the leading individual causes of death in combat and civilian trauma. The combination of these two injuries are very common, dramatically increasing the risk of death and long-term disability in survivors. In collaboration with Drs. Todd McKinley and Richard Rogers at the Indiana University Health System, CytoSorb blood purification was administered following direct cortical impact to the brain, an hour of hemorrhagic shock, and subsequent resuscitation in a rat trauma model. Treatment led to a reduction in a panel of key inflammatory cytokines during the treatment period that persisted for three days following the injury. More importantly, CytoSorb treatment resulted in more than a doubling of survival, from 41% in the sham treated group (N=17), to 86% survival in the CytoSorb treated group (N=14), that was highly statistically significant, p<0.01. These data have opened up an entirely new treatment strategy using CytoSorb for these life-threatening conditions which today have few therapeutic options.
- K+ontrol™: Crush Injury and Hyperkalemia: Trauma and crush injury to soft tissue can lead to rapid cell death and the release of a flood of intracellular potassium into the bloodstream. In compromised patients, very high levels of potassium in the blood, or severe hyperkalemia, can lead to dangerously irregular heartbeats called arrhythmias, and sudden cardiac death. This is particularly common in combat casualties, everyday civilian trauma, and mass casualty events such as earthquakes and terrorist bombings. Normally, hemodialysis is the definitive therapy to treat hyperkalemia. However in remote locations, during prolonged field care in combat, in areas that lack modern medical facilities, or in situations where the numbers of victims outstrip available dialysis equipment and supplies, there is a major need for simple, but effective ways to rapidly treat severe hyperkalemia. In collaboration with Dr. Ian Stewart from Travis Air Force Base, and Dr. James Ross at Oregon Health and Science University, the company has successfully developed a new blood purification approach to treat hyperkalemia that does not require dialysate or extra fluids. In a porcine model of severe hyperkalemia, where the pigs had no kidney function and potassium was infused intravenously at a constant rate to mimic crush injury, the new system was able to reduce potassium from severe hyperkalemia levels of approximately 7.9-8.5 mEq/L seen in the control animals, where several animals developed spontaneous near fatal cardiac arrhythmias, to a more normal to mild hyperkalemia range of 4.0-5.6 mEq/L that was sustained over 6 hours. The ability to simplify treatment and eliminate dialysate and replacement fluids removes an enormous logistical burden for military operations.
In addition, the company showcased another system to treat severe hyperkalemia that does not rely on blood purification at all, but instead uses a modified version of peritoneal dialysis which is widely used throughout the world to treat kidney failure patients. Peritoneal dialysis involves putting fluid into the abdominal cavity via a catheter, and utilizes the high surface area of the intestinal organs and abdominal wall as a natural dialysis membrane. Substances, such as potassium, ammonia, urea, and other toxins, flow from the blood, across this membrane, and into the fluid. Then the fluid is periodically drained and replaced. The new system uses our potassium binding sorbent to continuously bind and reduce potassium in the fluid (and indirectly from blood) without needing to replace the fluid. This is a system that can be implemented easily by medics or medically competent personnel in the field, requires no significant equipment, hardware, or electricity, and can be used in remote or mass casualty situations.
- HemoDefend™: Fresh Whole Blood and Universal Plasma Transfusion: Fresh whole blood (FWB) is considered by most military healthcare experts to be superior to blood component transfusions, such as packed red blood cells, in terms of its ability to restore blood volume and to stop bleeding in trauma. An additional advantage of FWB is that it can be directly given by a “walking donor” to the victim at the site of the accident, without the normal logistics and supply chain issues of refrigerated blood. Freeze-dried plasma is another important tool used to resuscitate trauma victims that can be easily carried without the need to refrigerate it. However, the presence of anti-A and anti-B blood group antibodies in both FWB and plasma can lead to dangerous transfusion reactions, therefore requiring very stringent blood-type and antibody level testing. The company highlighted data from the development of new sorbents under the HemoDefend™ brand that are capable of reducing these antibodies from both fresh whole blood and plasma in an ongoing R&D program.
Dr. Phillip Chan, Chief Executive Officer of CytoSorbents stated, “We are pleased to advance our CytoSorb®, HemoDefend®, and K+ontrol platforms for the treatment of traumatic brain injury, shock from severe blood loss, and severe hyperkalemia from massive trauma. These are life-threatening conditions that have killed and continue to kill both civilians and military servicemembers of our country and allies, and represent new markets where we can help to potentially save lives. We are grateful for the funding support that has helped us to rapidly and successfully develop these new therapies with our collaborators and are committed to translating these exciting advances from animal models to the bedside as quickly as possible.”
