Burkitt Lymphoma

Burkitt lymphoma (BL) is the most common pediatric cancer in sub-Saharan Africa and is associated with Epstein-Barr Virus (EBV). In a proof of principle study, we demonstrated increased EBV viral particles in tumor biopsies after the first dose of cyclophosphamide, suggesting that the virus had converted to a lytic infection. During the lytic cycle, EBV expresses proteins that make it susceptible to antiviral therapy.  In a phase I study of pediatric patients with Burkitt lymphoma, we found that combination therapy with CPM and valacyclovir had a comparable safety profile to CPM monotherapy in children with endemic Burkitt lymphoma. We recommend that the valacyclovir recommended Phase II dose be 30 mg/kg, 3 times daily.  We are currently seeking funding for this phase II trial.
