Summary

Dr. McCullough is an international leader in transfusion medicine research and practice and in clinical trials involving transfusion for treating diseases of the blood and bone marrow as well as bleeding conditions. In recent years he has focused his research primarily in two areas: clinical trails involving transfusion medicine; and blood donation and blood banking practices in developing countries.

Research

Research Summary/Interests

McCullough has a longstanding interest in clinical trials including randomized controlled clinical trials relating to blood transfusion, cell therapies and platelet therapies. He was the University’s principal investigator (PI) for the NIH-funded Transfusion Medicine / Hemostasis Clinical Trials Network (CTN), a 12-year study involving 17 sites launched in 2002. The network evaluated blood products and cytokines used to treat hemostatic and hematologic disorders in adults and children with the goal of facilitating optimal therapies. Through the CTN McCullough’s team conducted a clinical trial for platelet transfusion to determine optimal platelet dosage for the control of bleeding and a related trial exploring platelet transfusion frequency and cost. McCullough and his CTN colleagues recently explored the effects of red-cell duration storage on patients undergoing cardiac surgery. They found that transfusion of red cells stored for 10 days or less was not superior to the transfusion of red cells stored for 21 days or more.

Several of the clinical trials in which McCullough has participated have involved pathogen inactivation, which involves treating blood products after they are collected to eliminate contaminating viruses or bacteria, thereby making the blood products safe to transfuse. McCullough was PI for a large, definitive phase III clinical trial involving platelets treated with a psoralen compound in conjunction with ultraviolet light, which together lock up nucleic acids through crosslinking and prevent cells and viruses in blood products from replicating. The FDA approved the approach for platelet transfusion in 2014 and authorized a phase IV post-marketing clinical trial, which McCullough and his colleagues will undertake. McCullough is also one of three PIs in a controlled clinical trial for an alternative approach pathogen inactivation approach that involves riboflavin (vitamin B2) and ultraviolet light, which when used together release toxic compounds that damage nucleic acids and prevent DNA replication. Dr McCullough has carried out clinical trials of pathogen inactivation of plasma in patients who were acutely bleeding, typically liver disease and liver transplant patients, and of red cell transfusion in patients undergoing cardiovascular surgery.

Because of his experience conducting clinical trials, McCullough also serves on the Drug Safety and Monitoring Board committee of a clinical trial focused on screening plasma obtained from Liberian patients who have recovered from Ebola infection. Clinical evidence suggests that antibodies from reconvalescent donors (persons who have recovered from infection) may be effective in the treatment of Ebola virus infection. In addition, he has advised the Italian National Blood Transfusion Service regarding conduct of a clinical trial of pathogen-inactivated platelet transfusion.

On the international front, McCullough contracted with the Centers for Disease Control and Prevention in three projects – in Tanzania, Uganda, and Afghanistan -- on two of which he has served as PI. The projects involved collaborating with the national blood programs of these countries to advance blood availability and blood safety. McCullough and his colleagues worked to strengthen blood donor recruitment programs, improve the quality of blood product testing, and provide transfusion medicine education for physicians, among other activities. While McCullough sees signs of systemic improvement, many technical and social challenges remain to modernize blood donation, testing, and medical use in these countries given their limited medical and public health infrastructures.
