Phase I Study of Vorinostat in Combination With Niacinamide, and Etoposide for the Treatment of Patients With Relapsed and Refractory Lymphoid Malignancies

The purpose of this study is to test the safety of a combination of two anticancer
medicines, called vorinostat and etoposide, with a high dose of a vitamin called
niacinamide. These medications will be tested at different dose levels. The investigators
want to find out what effects, good and/or bad, it has on patients and their recurrent
lymphoma. The first two drugs, vorinostat and niacinamide, suppress survival signals that
lymphoma cells depend on. The third drug, etoposide can kill sensitive lymphoma cells alone
or in combination with other chemotherapy drugs. Vorinostat is an anticancer agent that been
approved by the Food and Drug Administration for use in cutaneous T-cell lymphoma. It is
being evaluated in this study in combination with other anticancer medicines for use in
other types of lymphoma. Vorinostat's use in combination with anticancer regimens is
experimental. Niacinamide is a vitamin that is investigational or experimental when given at
high doses as an anticancer agent. Niacinamide has not yet been approved by the Food and
Drug Administration for use in lymphoma. Etoposide has been approved by the Food and Drug
Administration for use in aggressive non-Hodgkin's lymphoma. However, the way it will be
given in this clinical study is experimental.

Subjects will be treated with vorinostat administered orally with daily dosing for 14 days
of a 21-day treatment cycle in combination with niacinamide administered orally for 14 days
in 21-day treatment cycle and etoposide administered intravenously on days 8,9 and 10 of a
21-day treatment cycle. Etoposide dose will be escalated until MTD is determined.
