A Pharmacokinetic and Pharmacodynamic Study to Evaluate the Safety and Feasibility of Continuous Infusion Nelarabine in Patients with Relapsed / Refractory Lymphoid Malignancies.
The goal of the clinical research study is to find the highest tolerable dose of nelarabine when given as a continuous infusion to patients with a lymphoid malignancy that has not responded to, or has come back after treatment with chemotherapy. The safety of this drug will also be studied.
Disease Group: Leukemia
Treatment Agent: Nelarabine
Treatment Location: Only at MDACC
Estimatated Length of Stay in Houston: If hospitalized, length of hospitalization would be 5 days every 28 days.
Return Visit: Weekly
Home Care: N/A
Primary Objectives · To determine the toxicity profile and maximum tolerated dose (MTD) of a 5-day continuous infusion schedule of nelarabine. Secondary Objectives · To assess the pharmacokinetics of infusional nelarabine. · To assess leukemic cell ara-GTP levels during infusional nelarabine. · To describe the response rate among different histologies (exploratory aim).
IRB Review and Approval Date: 06/08/2010
Recruitment Status: Closed
Projected Accrual: N/A
1) Patients must have one of the following relapsed/ refractory lymphoid
malignancies: Chronic lymphocytic leukemia (CLL), small lymphocytic
lymphoma (SLL) or B-prolymphocytic leukemia which has been previously
treated with a purine analog, and are not candidates for higher priority
clinical studies. Follicular lymphoma, mantle cell lymphoma,
lymphoplasmacytoid lymphoma or marginal zone lymphoma which has been
previously treated with autologous or allogeneic stem cell transplantation.
2) Continued from #1:T-cell prolymphocytic leukemia, large granular lymphocyte leukemia, mycosis fungoides / Sezary syndrome or peripheral T-cell lymphoma which has been previously treated with at least one line of chemotherapy or monoclonal antibody therapy. T-cell or B-cell acute lymphoblastic leukemia (ALL) which has been previously treated with at least one line of chemotherapy.
3) Patients (both pediatrics and adults) must have adequate renal function (calculated creatinine clearance >/= 50ml/min). For adults this will be calculated per the Cockgroft-Gault formula and in pediatric cases this will be calculated per the Schwartz formula.
4) Patients must have adequate hepatic function (bilirubin </= 2 mg/dL; SGOT or SGPT </= 3X the ULN for the reference lab unless due to leukemia).
5) Patients must have adequate marrow function (neutrophils >/= 0.5x10^9/L and platelets >/= 50x10^9/L) unless cytopenias are deemed due to disease.
6) Patients must have adequate performance status (Zubrod 0-2).
7) Female patients must not be pregnant or lactating. Female patients of childbearing potential (including those <1 year postmenopausal) and male patients must agree to use contraception.
8) Patients must sign an informed consent form indicating that they are aware of the investigational nature of this study, in keeping with the policies of the hospital.
1) Patients must not have untreated or uncontrolled life-threatening infection.
2) Patients known to be HIV positive or known to have Hepatitis B and/or C are excluded.
3) Patients must not have received systemic chemotherapy or monoclonal antibody therapy within 2 weeks of study enrollment. Patients who have previously received bolus nelarabine are still eligible. Hydroxyurea or corticosteroids for control of blood counts is allowed, but must be discontinued 24 hours prior to initiating nelarabine.
4) Patients must not have a history of grade >/=2 neurological toxicity with previous treatment, or persistent grade >/=2 peripheral neuropathy. Drowsiness and lethargy were exempted from this criteria unless previously persistent for more than one week.
5) Patients must not have uncontrolled central nervous system disease. Patients with a history of seizure disorders must be seizure-free for one year prior to enrolment.
6) Patients must not have any other medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with a patient’s ability to give informed consent or cooperate and participate in the study or interfere with the interpretation of the results.
