Flavopiridol to Treat Relapsed Mantle Cell Lymphoma or Diffuse Large B-Cell Lymphoma

• Status: Completed
• Trial end date: 2012-10-18
• Target enrollment: 0
• Participant gender: All

Summary

Background:

Mantle cell lymphoma (MCL) and diffuse large B-cell lymphoma (DLBCL) are aggressive subtypes of non-Hodgkin lymphoma.

Flavopiridol is an investigational drug that works differently from standard chemotherapy and may target abnormalities in MCL and DLBCL cells, such as a protein excess that prevents tumor cells from dying.

A challenge in developing flavopiridol for treatment has been determining its optimal dosing schedule. The schedule used for this study is effective in a type of leukemia called chronic lymphocytic leukemia (CLL) and may benefit patients with MCL and DLBCL also.

Objectives:

To determine the highest dose of flavopiridol that can be given safely to patients with relapsed MCL and DLBCL at the dosing schedule detailed below

To assess the response of the tumor to flavopiridol given at the test dosing schedule

Eligibility:

Patients 18 years of age and older with relapsed MCL or DLBCL

Design:

Flavopiridol is given at four different dose levels, starting with the lowest dose for the first group of three to six patients and increasing with subsequent groups, depending on side effects at the preceding dose. The drug is given weekly for 4 weeks followed by a 2-week break (one cycle) for up to six cycles. It is given through a vein as a 30-minute infusion followed by a 4-hour infusion.

Patients undergo the following procedures for research studies and to evaluate the effect of treatment on the tumor:

• Blood tests

• Lymph node, bone marrow and tumor biopsies

• Lymphapheresis to collect blood cells for research

• Disease staging with imaging studies (computed tomography (CT), positron emission tomography (PET) and/or magnetic resonance imaging (MRI) after every 2 cycles

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Alvocidib

Criteria

• ELIGIBILITY CRITERIA:

Previously treated mantle cell lymphoma or diffuse large B-cell lymphoma (to include mediastinal (thymic) large B-cell lymphoma; transformed large B-cell lymphoma; follicular grade IIIB large B-cell lymphoma; intravascular large B-cell lymphoma).

Confirmed pathological diagnosis at the National Cancer Institute, National Institutes of Health (NIH).

Recurrent measurable disease (measurable disease in 2 dimensions or leukemic disease which can be quantified and followed).

Prior anthracycline-based treatment for patients with diffuse large B-cell lymphoma (DLBCL).

Age greater than 18 years.

Eastern Cooperative Oncology Group (ECOG) performance 2 or better.

Major organ function: absolute neutrophil count (ANC) greater than 1000/mcL, Platelet greater than 50,000/mcL, Creatinine less than 1.5 mg/dL or creatinine clearance greater than 60 mL/min; serum glutamic pyruvic transaminase (SGPT) less than 5 x upper limit of normal; bilirubin less than 2 mg/dL (total) except less than 5 mg/dL in patients with Gilbert's syndrome as defined by greater than 80% unconjugated. ANC and platelet requirements must be met independent of transfusion.

Informed consent and willingness to use contraception by both men and women.

Both male and female patients must be willing to use adequate contraception (to include effective barrier methods of contraception) or to completely abstain from heterosexual intercourse while on protocol treatment.

EXCLUSION CRITERIA:

Pregnant or nursing because of an unknown potential for teratogenic or abortifacient effects.

Human immunodeficiency virus (HIV) serology negative. HIV positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with flavopiridol. Additionally, the biology of HIV associated DLBCL's is often quite different from HIV negative disease due to involvement of Epstein Barr virus (EBV).

Hepatitis B surface antigen negative.

Active central nervous system (CNS) lymphoma. These patients have a poor prognosis and because they frequently develop progressive neurological dysfunction that would confound the evaluation of neurological and other adverse events.

History of inflammatory bowel disease unless this has been inactive for a period of 2 or more years.

Recovery from toxicity of prior therapy to a grade 1 or less.

Systemic cytotoxic or experimental treatments within 4 weeks of treatment.

White blood cell (WBC) greater than 100,000 cells/mcL.
