Study of Arginine Butyrate and Ganciclovir/Valganciclovir in EBV(+) Lymphoid Malignancies

Phase 2

Terminated

Interventions: Drug: Arginine Butyrate
Drug: Ganciclovir
Drug: Valganciclovir

Brief Summary: The purpose of this study is to assess whether administration of Arginine Butyrate + ganciclovir/valganciclovir for up to three 21-day cycles is tolerable, and results in partial or complete responses in patients with EBV(+) lymphoid malignancies.

(iv) AST (SGOT)/ALT(SGPT) of ≤ 2.0 x institutional upper limit of normal. (v) creatinine within normal range for institution.

Exclusion Criteria

Patients that have received chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entry, or those who have not recovered form adverse events due to agents administered 4 weeks earlier.
Patients may not be receiving any other investigational agents.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to Arginine Butyrate, ganciclovir or valganciclovir.
Patients who have an acute myocardial infarction or onset of atrial fibrillation within the past 6 months.
Uncontrolled intercurrent illness including, but not limited to , ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Primary Outcome Measures

Name	Time	Method
Response Rate (using Revised Response Criteria for Malignant Lymphoma, Cheson et al., JCO 2007)	Every three weeks. If a response is recorded evaluation continues until an objective determination of disease progression is made (assessment may continue after treatment is discontinued.)

Secondary Outcome Measures

Name	Time	Method
Progression Rate (using Revised Response Criteria for Malignant Lymphoma, Cheson et al., JCO 2007)	Every three weeks. If a response is recorded evaluation continues until an objective determination of disease progression is made (assessment may continue after treatment is discontinued.)
Safety as assessed by (1) adverse events, (2) laboratory values (3) vital signs (4) physical exam	Up to three 21-day cycles. If a response is recorded evaluation continues until an objective determination of disease progression is made (assessments may continue after treatment is discontinued.)
