Phase I Trial of Clofarabine in Combo w/ HD Etoposide & Cyclophosphamide and APBSCT for Pts w/ High-Risk or Refractory NHL

NCT ID: NCT00477945

Last Updated: 2014-09-11

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 18 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2007-05-31
• Study Completion Date: 2010-11-30

Brief Summary

This is a phase I trial to determine the maximum tolerated dose (MTD) of clofarabine in a combination with high-dose etoposide and cyclophosphamide. This is an initial step in developing a novel myeloablative preparative regimen for autologous hematopoietic stem cell transplantation (ASCT). While this phase I trial will initially develop the regimen in patients with refractory disease, it is expected that it will find its best application in patients with less advanced disease.

Detailed Description

All patients will receive the same doses of etoposide and cyclophosphamide. The dose of clofarabine will be escalated in successive cohorts of patients. Using a standard dose escalation design, successive cohorts of 3 patients will be treated with escalating doses of clofarabine (see Section 5.5 below). At the MTD (or highest dose-level if the MTD is not reached), the cohort will be expanded to 10 patients to better investigate correlative studies and give some preliminary idea of efficacy.

Eligibility Criteria

Inclusion Criteria

1. Documentation of disease. Patients must have one of the following disease types:

• Diffuse large cell non-Hodgkin's lymphoma, mediastinal B-cell lymphoma, or peripheral T-cell lymphoma that is:

• Primary refractory (achievement less than complete response)
• Relapsed and refractory (achievement less than a partial response) to at least a single salvage therapy
• Relapsed or primary refractory Follicular lymphoma (FL) with a high FL International Prognostic Index.
• Large cell transformation of lymphoma from a more indolent lymphoma (e.g., follicular, marginal zone, etc.)
• Mantle cell lymphoma that is:

• Primary Refractory (achievement less than complete response)
• Relapsed (regardless of chemosensitivity of relapsed disease)

2. Patients who received prior autologous stem cell transplantation are not eligible.

3. Patient age 18-70 years

4. Performance status ECOG 0-1

5. Required baseline laboratory values:

• LVEF > 45% corrected
• DLCO > 50% of predicted value (corrected for hemoglobin)
• Serum creatinine ≤ 2.0 mg/dl or estimated creatinine clearance of ≥60 ml/min
• Bilirubin < 1 x upper limit of normal value.
• AST and ALT < 1 x upper limit of normal value.

6. Signed written informed consent. Patient must be capable of understanding the investigational nature of the investigational nature, potential risks and benefits of the study, and able to provide valid informed consent

Exclusion Criteria

1. No active infection. Patients with active infections requiring oral or intravenous antibiotics are not eligible for enrollment until resolution of infection.

2. No HIV disease. Patients with immune dysfunction are at a significantly higher risk of infection from intensive immunosuppressive therapies.

3. Non-pregnant and non-nursing. Treatment under this protocol would expose a fetus to significant risks. Women of childbearing potential should have a negative pregnancy test prior to study entry. Women and men of reproductive potential should agree to use an appropriate method of birth control throughout their participation in this study due to the teratogenic potential of the therapy utilized in this trial. Appropriate methods of birth control include oral contraceptives, implantable hormonal contraceptives (Norplant®), or double barrier method (diaphragm plus condom).

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 70 Years
