Malignancies associated with latent Epstein-Barr virus (EBV) are resistant to nucleoside-type antiviral agents because the viral enzyme target of these antiviral drugs, thymidine kinase (TK), is not expressed. Short-chain fatty acids, such as butyrate, induce EBV-TK expression in latently-infected B-cells. As butyrate has been shown to sensitize EBV(+) lymphoma cells in vitro to apoptosis induced by ganciclovir, Arginine Butyrate in combination with ganciclovir was administered in fifteen patients with refractory EBV(+) lymphoid malignancies to evaluate the drug combination for toxicity, pharmacokinetics, and clinical responses. Ganciclovir was administered twice daily at standard doses and Arginine Butyrate was administered by continuous infusion in an intra-patient dose-escalation, from 500 mg/kg/day escalating to 2000 mg/kg/day, as tolerated, for a 21-day cycle. The MTD for Arginine Butyrate in combination with ganciclovir was established as 1000 mg/kg/day. Ten of fifteen patients showed significant anti-tumor responses, with four CR and six PR within one treatment cycle. Complications from rapid tumor lysis occurred in three patients. Reversible somnolence or stupor occurred in three patients at Arginine Butyrate doses of greater than 1000 mg/kg/day. The combination of Arginine Butyrate and ganciclovir was reasonably well-tolerated and appears to have significant biological activity in vivo in EBV(+) lymphoid malignancies which are refractory to other regimens.
