Condition(s) targeted: Chronic Myelogenous Leukemia
Intervention: Imatinib Mesylate (IM) (Drug); TALL-104 cells (Drug)
Phase: Phase 2
Status: Terminated

Summary
Objectives:
- To determine the response rate and duration of response with combination of TALL-104
cells and imatinib mesylate (IM) therapy in patients with chronic myelogenous leukemia
in chronic phase, that have not achieved, or have lost, adequate response to IM.
- To determine the toxicity of the combination of TALL-104 cells and IM therapy in this
patient population.
Clinical Details
Official title: Phase II "Proof of Concept" Study of TALL-104 (MHC Non-Restricted Cytotoxic T-Cell Line) and Imatinib Mesylate (Gleevec) in Chronic Myelogenous Leukemia in Chronic Phase
Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Response Rate (Major and Complete Cytogenetic Response)
Detailed description:
Imatinib mesylate is designed to block the enzyme that is believed to be responsible for
starting the type of leukemia patient has. TALL-104 cells are cells of the immune system
that have been obtained from a patient with leukemia and then processed in the laboratory to
try to make them able to kill leukemia cells.
If found to be eligible to take part in this study, patient will continue receiving imatinib
mesylate by mouth at the same schedule and dose patient had been receiving before entering
the study. Patient will receive TALL-104 cells through a needle in their vein over 1 hour
on Days 1-4, and then again on Days 7, 10, 14, 17, and 21 of the cycle. The cycle will last
28 days.
Blood (about 1 tablespoon) will be drawn every week for the first 4 weeks, then every 2-4
weeks for 2 months, then every 4-6 weeks until 6 months, and then every 3-6 months for
routine tests and to check for any effect on organs.
Patient will have follow-up visits at 1 month, 3 months, 6 months, and at least annually for
2 years, and then at least every 5 years from then on for the rest of your life. Blood
(about 1 teaspoon) will be drawn to check the status of the disease. An additional 1
tablespoon will also be collected and stored to be analyzed in case unexpected side effects
occur after receiving therapy. If patient experiences certain side effects, more blood may
need to be drawn and more tests performed based on the side effects experienced.
Up to 20 patients will take part in this study. All will be enrolled at M. D. Anderson.
Eligibility
Minimum age: 18 Years.
Maximum age: N/A.
Gender(s): Both.
Criteria:
Inclusion Criteria:
1. Patients with CML in chronic phase who have failed to achieve or have lost an
adequate response to IM. For the purpose of this trial this will be defined as a lack
of any cytogenetic response after 6 months of therapy or lack of major cytogenetic
response after 12 months of therapy with IM. Patients that have lost their major or
complete cytogenetic response will also be eligible. Patients who show a sustained
increase in breakpoint cluster region gene (BCR)-Abelson gene (ABL)/ABL [BCR-ABL/ABL]
ratio of >/= 1-log confirmed in at least two consecutive Polymerase Chain Reaction
(PCR) analyses (at least one month apart from each other) will also be eligible.
2. *continued from above: Patients with stable molecular response defined as 2
consecutive PCR-positive results (no more than 1/2 log improvement) will also be
eligible. Patients must be taking stable dose of IM for at least 3 months before
study enrollment, and recovered from all toxicities related to IM, to grade 0-1.
3. Patients should be in complete or partial hematological remission, including white
blood count (WBC) =20 x 10(9)/L, and platelets = 600 x 10(9)/L.
4. Eastern Cooperative Oncology Group (ECOG) scale performance status of 2 or less.
5. Age greater than 18 years of age since disease is extremely rare in younger age
groups.
6. Adequate liver (total bilirubin of less than 2 times and aspartate aminotransferase
(AST) or alanine aminotransferase (ALT) of less than 2 times upper limits of normal),
and renal function (creatinine of less than 2 times upper limit of normal).
7. Signed informed consent form.
8. Negative pregnancy test in women of childbearing age.
9. Negative hepatitis B and C screening blood tests.
Exclusion Criteria:
1. Serious intercurrent medical illnesses or active infections requiring parenteral
antibiotics that would interfere with the ability of the patient to carry out the
treatment program.
2. Female patients who are pregnant or breast-feeding.
3. Patients taking steroids, or those anticipated to receive steroids during the trial
therapy.
4. Prior bone marrow transplant.
5. Known positivity for human immunodeficiency virus (HIV).
