About Hemanext

Hemanext is a privately held medical technology company based in Lexington, MA that is dedicated to improving the quality, safety, efficacy, and cost of transfusion therapy. The company’s research and development efforts focus on the study of hypoxically stored red blood cells (RBCs). The company’s aim is to significantly improve the quality of stored RBCs worldwide.

About Hemanext ONE

Hemanext ONE has been granted marketing authorization for commercial distribution via the De Novo process by the U.S. Food & Drug Administration. It is intended to process and store CP2D/AS-3 Red Blood Cells, Leukocytes Reduced (LR RBC) that have been prepared within the standard 8-hour hold time. Processing of Red Blood Cells processed with the HEMANEXT ONE system must be initiated within 8 hours of collection and completed within 12 hours of collection. The Red Blood Cells must be processed at room temperature (20-26°C). The HEMANEXT ONE system limits O2 and CO2 levels in the storage environment. Red Blood Cells Leukocytes Reduced, O2/CO2 Reduced may be stored for up to 42 days at 1-6°C. HEMANEXT ONE is used for volumes no greater than 350 mL of LR RBC.

In Europe, Hemanext ONE is CE marked, which allows its commercial distribution within the market of the European Economic Area (EEA).

The HEMANEXT ONE RBC Processing and Storage system limits oxygen, the fuel for oxidative damage, providing a higher quality blood product.1,2,3 It has the potential to benefit all patients requiring transfusion for chronic conditions, such as thalassemia4, sickle cell disease (SCD)5, and myelodysplastic syndromes (MDS),6 as well as those in need of critical transfusions during acute bleeding in surgery, trauma and other medical procedures.7

HEMANEXT ONE creates hypoxic RBCs, RBCs that have been processed to reduce oxygen and carbon dioxide content of RBCs and to maintain these levels throughout storage up to 42 days.3 Hypoxic RBCs have demonstrated positive impacts on multiple in vitro metrics of RBC quality in preclinical studies.8,9 Clinical studies are underway to determine the impact of hypoxic RBCs on patient outcomes and estimate potential cost savings from expected improvements in care and reductions in transfusion volumes.10

By producing higher quality RBCs, the Hemanext ONE system has the potential to enable fewer and more effective transfusions for patients. I am truly excited by the possibility of bringing this improved red blood cell replacement therapy to populations in the U.S. that have been waiting for a transformative technology like this one.

We value our partnership with Hemanext to enhance blood product quality and availability. Hemanext ONE has the potential to strengthen the resiliency of the blood supply, and this FDA authorization is a significant milestone to that end.

Ralph Vassallo, MD, FACP
Executive Vice President, Chief Medical and Scientific Officer of Vitalant

The Hemanext ONE system offers promise to improve the treatment landscape for patients burdened by transfusions and could be an essential step towards performing fewer and better transfusions. Having long championed Hemanext’s transformative initiatives, I eagerly anticipate witnessing the positive influence, right here in the United States, on the advancement of transfusion therapy quality.

By deoxygenating red cells and maintaining them in their hypoxic state throughout storage, the resulting red cells experience less oxidative stress and oxidative damage, have improved metabolism, and are also more deformable leading to improved micro vascular profusion and less hemolysis.

Dr. Steven Spitalnik, MD
Co-Director of the Laboratory of Transfusion Biology, Colombia University

The preclinical data by Williams et al. show anaerobically stored RBCs achieve multiple clinically important functional resuscitation goals, with a smaller volume of fluid and the FDA benchmark of 24-hour RBC recovery. I look forward to the clinical trials in bleeding patients.

John Holcomb, MD, FACS
University of Alabama at Birmingham

I have had several patients who have received Hemanext hypoxic blood, and several of the patients have personally said thanks for having been given the opportunity and also that they have felt better after transfusion with hypoxic blood compared to conventional transfusion. One must of course be careful not to attach too much importance to such observations, but I would still like to mention that there has been a remarkable tendency towards this.
