Study Details

Study Description

Brief Summary

The first part of the study is to evaluate and determine if three different forms of MGCD0103 (free base FB-MGCD0103, tartaric acid free base [TA-FB-MGCD0103], and dihydrobromide [2HBr] salt formulation MGCD0103) have the same properties when given to patients with cancer. The second part of the study is to determine whether MGCD0103 administered in combination with azacitidine is effective and safe in treating subjects with relapsed or refractory Hodgkin's lymphoma or non-Hodgkin's lymphoma (NHL) (follicular or diffuse large B-cell [DLBCL]).

Condition or Disease	Intervention/Treatment	Phase
Hodgkin Lymphoma Non-Hodgkin Lymphoma (Follicular or Large Diffuse B-cell Lymphoma or Mantle Cell Lymphoma)	Drug: MGCD0103 and Azacitidine	Phase 2

Detailed Description

MGCD0103 and FB-MGCD0103 belong to a class of drugs known as histone deacetylase inhibitors (also called HDAC inhibitors). Azacitidine belongs to a class of anti-cancer drugs known as DNA de-methylating agents. Azacitidine (Vidaza®) was approved by the Food and Drug Administration (FDA) in 2004 for the treatment of myelodysplastic syndromes (MDS).

The combination of MGCD0103 and azacitidine has been given to about 50 people with leukemia or MDS in other clinical studies. This is the first study where the combination will be tested in people with lymphoma. Specifically, the study is designed to understand the following:

How long single doses of TA-FB-MGCD0103, FB-MGCD0103 and MGCD0103 stay in the body, OR
How long different doses of TA-FB-MGCD0103 and FB-MGCD0103 stay in the body; and
How long MGCD0103 stays in the body when given with azacitidine; and
What effect MGCD0103 and azacitidine have on the body and the study subject's type of lymphoma; and
If the genetic and chemical make-up of the study subject's blood and/or tumor play a role in how she/he responds or does not respond to MGCD0103 and azacitidine.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: 1	Drug: MGCD0103 and Azacitidine In Part 1 of the study, up to 22 people to enroll will receive a single, oral dose (75 mg gelcap) of MGCD0103 and FB-MGCD0103 during their first 2 weeks in the study. Up to 22 additional people will receive a single dose of both MGCD0103 and TA-FB-MGCE0103. The next group of people to enroll will receive 2 different single doses (25, 50, 100 mg) of FB-MGCD0103 or TA-FB-MGCD0103 during their first 2 weeks in the study. In Part 2 of the study, from Day 1-5 of each 28-day cycle, all subjects will receive a dose of azacitidine (75 mg/m2) either subcutaneously or through an intravenous device, and on days 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, a single, oral dose (85 mg) of MGCD0103 until progression or unacceptable toxicity develops.

Outcome Measures

Primary Outcome Measures

Primary efficacy is measured by: 1) PET, CT & physical exam, 2) overall response rate (complete response=disease is gone, partial response=disease has improved). Study treatment continues as long as the cancer is stable & side effects are tolerable. [every other cycle of 28 days each]

Secondary Outcome Measures

Duration of response defined as: 1)the time of first documented objective response (either complete response or partial response) until the subject's disease gets worse, 2)how long his/her disease is stable. [28 days after the last study drug]

Eligibility Criteria
