Helocyte is a clinical-stage company developing novel immunotherapies for the prevention and treatment of cancer and infectious diseases, including cytomegalovirus (“CMV”) and human immunodeficiency virus (“HIV”). The Centers for Disease Control estimate that 50 to 80 percent of Americans are living with CMV by the age of 40. While the virus is asymptomatic in healthy individuals, it can cause severe and life-threatening disease in those with weakened or uneducated immune systems. Patients undergoing allogeneic stem cell and solid organ transplantation are at particularly high risk of experiencing complications associated with CMV. According to the Center for International Blood and Marrow Transplant Research, there were approximately 9000 allogeneic (unrelated and related) bone marrow and cord blood transplants performed in the United States in 2023. According to preliminary data from the Organ Procurement and Transplantation Network, there were over 46,000 organ transplants performed in the United States in 2023, comprised primarily of kidney and liver transplant procedures. Helocyte’s Triplex vaccine is engineered to induce a robust and durable virus-specific T cell response to control CMV in transplant recipients. While current antiviral therapies have reduced the rate of CMV disease-related mortality in transplant recipients, such treatments have been linked to increased toxicity, delayed immune reconstitution and late onset of CMV. The Helocyte vaccines may also educate the body’s innate immune system to fight CMV. For more information, please visit www.helocyte.com.
