Clinical Trial Summary

This phase I trial studies the side effects and best dose of CPI-613 (6,8-bis[benzylthio]octanoic acid) when given together with bendamustine hydrochloride and rituximab in treating patients with B-cell non-Hodgkin lymphoma that has come back or has not responded to treatment. Drugs used in chemotherapy, such as 6,8-bis(benzylthio)octanoic acid and bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may find cancer cells and help kill them. Giving 6,8-bis(benzylthio)octanoic acid with bendamustine hydrochloride and rituximab may kill more cancer cells.

Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of CPI-613, when used in combination with bendamustine (bendamustine hydrochloride) and rituximab in patients with relapsed or refractory B-cell non-Hodgkin lymphoma (NHL), who have or have not received hematopoietic cell transplant.

SECONDARY OBJECTIVES:

I. To evaluate response rate (RR) and disease control rate (DCR), derived from the modified International Work Group (IWG) criteria.

II. To evaluate overall survival (OS) and progression-free-survival (PFS), and possible correlation between RR and DCR derived from the modified IWG criteria vs. OS and PFS.

III. To evaluate assessment of bone marrow biopsy, and possible correlation between complete response (CR) vs. bone marrow biopsy assessment (e.g., clear of infiltration of leukemic cells accordingly to morphology, and/or negative on leukemic cells according to immunohistochemistry).

IV. To evaluate safety of the CPI-613 + bendamustine + rituximab combination.

OUTLINE: This is a dose-escalation study of 6,8-bis(benzylthio)octanoic acid.

Patients receive 6,8-bis(benzylthio)octanoic acid intravenously (IV) over 2 hours on days 1-4 (week 1) and days 1 and 4 (weeks 2 and 3). Patients also receive bendamustine hydrochloride IV over 30 minutes on days 4 and 5 and rituximab on day 5 of week 1. Treatment repeats every 4 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 months.

• Having "currently active" second malignancy unrelated to Hodgkin lymphoma (HL) or NHL, unless they have completed anti-cancer therapy, are in complete response and are considered by their physicians to be at less than 30% risk of relapse

• Patients receiving any other standard or investigational treatment for their cancer, or any other investigational agent for any indication, within the past 2 weeks prior to initiation of treatment with study drugs

• Serious medical illness that would potentially increase patients' risk for toxicity

• Any active uncontrolled bleeding, and any patients with a bleeding diathesis (e.g., active peptic ulcer disease)

• History of abdominal fistula or gastrointestinal perforation =< 6 months prior to treatment with study drugs

• Pregnant women, or women of child-bearing potential not using reliable means of contraception

• Lactating females

• Fertile men unwilling to practice contraceptive methods during the study period

• Any condition or abnormality which may, in the opinion of the investigator, compromise the safety of patients

• Unwilling or unable to follow protocol requirements

• Active heart disease including but not limited to symptomatic congestive heart failure, symptomatic coronary artery disease, symptomatic angina pectoris, symptomatic myocardial infarction or symptomatic congestive heart failure

• Patients with a history of myocardial infarction that is < 3 months prior to registration

• Evidence of active infection, or serious infection within the past month

• Patients with known human immunodeficiency virus (HIV) infection, hepatitis B, or hepatitis C

• Patients who have received cancer immunotherapy of any type within the past 2 weeks prior to initiation of CPI-613 treatment

• Requirement for immediate palliative treatment of any kind including surgery
