Dr. Stefano Rivella, the study's senior author and assistant professor of genetic medicine in pediatrics at Weill Cornell Medical College, believes that he and his collaborators may have found a way around splenectomy. After giving mice with Cooley's a compound called JAK2 inhibitor, the researchers found that the mice's spleens shrunk to normal sizes, and they began to produce normal red blood cells. The chemical (a similar compound is already in a Phase I clinical trial for myelodysplastic syndromes -- another blood disorder) blocks the activity of the JAK2 gene that is highly expressed in Cooley's anemia, and is believed to play a crucial role in the malformation of red blood cells.

Striking at the Heart of Hepatitis B Virus
A New Drug May Wipe-Out Infection in More Patients

NewYork-Presbyterian/Weill Cornell clinician-scientists are studying how a new drug might be used to treat chronic hepatitis B infection (HBV). Clevudine is a compound that may provide a longer lasting viral suppression after treatment is stopped, compared to drugs currently prescribed to treat HBV. This new compound is being studied in subjects with chronic HBV who have never been treated before by one of the current standard medications for HBV. The drug blocks an enzyme called DNA polymerase in order to stop the replication of the HBV virus.

Dr. Ira Jacobson -- principal investigator of the study, chief of the Division of Gastroenterology and Hepatology at NewYork-Presbyterian/Weill Cornell, and Vincent Astor Distinguished Professor of Clinical Medicine at Weill Cornell Medical College -- says that the new drug may help many patients with HBV avoid a lifetime of taking drugs to control the infection.
