A Phase 2b Study of Molecular Responses to Imatinib (Gleevec) at Standard or Increased Doses, or Dasatinib (BMS-354825) (NSC-732517) for Previously Untreated Patients with Chronic Myelogenous Leukemia (CML) in Chronic Phase
This study is being done to:
- Find out what effects (good and bad) regular or increased doses of imatinib or
dasatinib has on a patient and their Chronic Myelogenous Leukemia (CML)
- Find out if giving a larger dose of imatinib will have any effect on the patient and their
CML or if giving the drug, dasatinib, will have any effect on the patient and their
CML.
- Find out which treatment works the best for CML in chronic phase when comparing
imatinib treatment at standard doses with higher doses of imatinib treatment and
with dasatinib treatment.

A Phase 3 Study of Clofarabine and Cytarabine (ara-C) for Older Patients With Relapsed or Refractory (Resistant) Acute Myelogenous Leukemia (AML)
This study is being done to find out what effects (good and bad) clofarabine (also called Clolar) has on a patient and their acute myelogenous leaukemia (AML). Clofarabine is currently approved by the U.S. Food and Drug Administration (FDA) for the treatment of pediatric patients with acute lymphoblastic leukemia (ALL) who have not responded or have relapsed after receiving two prior treatments. Early clinical studies using clofarabine in adult patients with AML were conducted. However, clofarabine is not approved by the FDA for the treatment of AML; it is still investigational in this disease. Cytarabine (also called ara-C) is an FDA approved chemotherapy that is given as a treatment for AML.

A Phase II Study of Sunitinib Malate (Sutent) for Treatment of Patients with Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)
Patients are being asked to take part in this research study because they have lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Sunitinib is an investigational anti-cancer agent that has not yet been approved by the U.S. Food and Drug Administration for use in CLL and SLL. This medication blocks a signaling pathway in tumor cells called the "VEGF pathway." In the laboratory, this pathway has been shown to be abnormal in CLL B-cells and to be used by these leukemia cells to prolong their survival. It is hoped that blocking this signaling pathway will lead to the death of CLL cells and improvement in the patient's condition.

Phase 2 Study to Evaluate the Safety and Efficacy of Monoclonal Antibody Lumiliximab in Combination with Fludarabine, Cyclophosphamide (Cytoxan), and Rituximab (Rituxan) Versus Fludarabine, Cyclophosphamide, and Rituximab Alone in Patients with Relapsed Chronic Lymphocytic Leukemia (CLL)
Patients are being asked to take part in this research study because their doctor has tested the patient's blood and/or bone marrow and determined that they have a diagnosis of relapsed Chronic Lymphocytic Leukemia (CLL). The purpose of the study is to compare the clinical benefit of Lumiliximab in combination with Fludarabine, Cyclophosphamide, and Rituximab (FCR) to FCR alone and to compare the safety of Lumiliximab when given in combination with FCR to FCR alone. This will include looking at what side effects occur and how often they occur.
Lumiliximab is an investigational drug made by Biogen Idec Inc. (Biogen Idec) that is
being studied for the treatment of relapsed chronic lymphocytic leukemia (CLL). Regulatory authorities have not yet approved lumiliximab for general use, but they have allowed it for use in clinical trials. Lumiliximab is a monoclonal antibody made of monkey and human proteins. A monoclonal antibody is a substance made in the laboratory that binds to a specific protein. Although doctors don't know exactly how lumiliximab works, it is believed that lumiliximab binds to a protein on CLL cells and causes them to die.
At the time of this summary, a total of 257 patients have received lumiliximab. This includes patients with CLL as well as patients with allergic disorders. In clinical trials in patients with CLL, lumiliximab has been given alone as well as with fludarabine, cyclophosphamide, and rituximab (FCR), a drug combination frequently used to treat people with CLL.
Fludarabine is a type of chemotherapy drug, which has been approved for the treatment of patients with CLL. Cyclophosphamide is another approved chemotherapy drug often given with fludarabine. Rituximab is a monoclonal antibody made of mouse and human proteins. It attaches to a specific protein found on most CLL cells. Rituximab has been approved in the US, Canada, and Europe for the treatment of some cancers. Although rituximab is commonly used for the treatment of CLL, it has not been approved for this disease.

Phase 3 Vaccine Study of Proteinase 3 PR1 Peptide Mixed with Montanide ISA-51 VG Adjuvant and Administered with GM-CSF in Elderly Patients with Acute Myelogenous Leukemia (AML) in First Complete Remission or Adults in Second Complete Remission: A Pivotal Study
Patients are being asked to take part in this research study because they have Acute Myelogenous Leukemia (AML) that is in complete remission. The goal of this research study is to see if a new vaccine (called PR1) can prolong the duration of their complete remission from AML and help patients live longer.
The PR1 vaccine consists of two components. The vaccine includes part of a protein that is made by the leukemia cells. This protein fragment is called a peptide. Another component of the vaccine is an oil-based liquid to help the body respond to the vaccine. The liquid is called an adjuvant. The name of the specific adjuvant in this study is Montanide ISA-51 VG. The vaccine may help fight leukemia by making a patient's normal white blood cells kill the leukemia cells. The vaccine is administered subcutaneously (under the skin, like an insulin shot) on a patient's thighs and arms.
Patients will also receive a drug called GM-CSF (granulocyte-macrophage colony stimulating factor) through a needle under the skin in the same area as the PR1 vaccine.
GM-CSF is a drug that makes blood cells grow and may also make the vaccine stronger.

A Dose-Finding Study of CpG 7909 in Previously Treated Chronic Lymphocytic Leukemia
The purpose of this research study is to evaluate the use of CpG 7909. CpG 7909 is a short strand of DNA, the genetic material found in cells. CpG 7909 has the potential to stimulate the immune system, and we are studying these effects to learn if CpG 7909 has potentially beneficial effects in people with chronic lymphocytic leukemia. The purpose of this research study is to see if we can measure biological changes in Chronic Lymphocytic Leukemia (CLL) cells and chemicals in your blood after receiving CpG 7909.

A Phase 3 Randomized Trial of Gemtuzumab Ozogamicin (Mylotarg) Combined with Conventional Chemotherapy for De Novo Acute Myeloid Leukemia (AML) in Children, Adolescents, and Young Adults
Acute myeloid leukemia (AML) is a cancer of the bone marrow, the spongy tissue inside the large bones of the body where blood cells are made. In AML, the bone marrow makes large numbers of immature white blood cells called blasts. These blast cells crowd out the normal cells of the bone marrow. They may flood the bloodstream and invade vital organs such as the brain, testes, ovaries, or skin. These cancerous AML cells can sometimes form a solid tumor called a chloroma.
The standard treatment for this disease is to use a combination of cancer-fighting drugs called chemotherapy. Chemotherapy destroys the leukemia cells in the blood and bone marrow. In the first phase, called Induction 1, the medical team tries to remove all visible signs of leukemia and allow normal blood cells to be restored. This is called remission. The next phase of treatment is called Induction 2. Induction 2 is another round of chemotherapy to kill the few remaining leukemia cells that may have survived Induction 1. In the next phase of treatment, called Intensification 1, more chemotherapy is used to kill any remaining blast cells. Then the medical team does a Stem Cell Transplantation (SCT) or gives additional high doses of chemotherapy to try to keep the leukemia from coming back.
Nearly 500 children are diagnosed with AML every year, and half are cured with standard therapy. In other words, half of the children diagnosed with AML and treated as described above remain with no signs of cancer (remission) for five years. The overall goal of this study is to see if the research staff can increase this cure rate without causing more serious side effects of therapy. Side effects are unintended and unwanted results of treatment.
Researchers want to know if they can improve the cure rate for AML by adding a new chemotherapy drug, called gemtuzumab, to the standard chemotherapy treatments.
Gemtuzumab has been studied in adults with AML in combination with standard chemotherapy drugs. It has also been studied in small groups of pediatric patients. These studies have determined what dose of gemtuzumab can be given safely with other chemotherapy drugs.
Another goal of this study is to determine which children with AML need a stem cell transplant and which children do not. During intensification treatment, the study doctors will assign patients to either receive more chemotherapy, or a stem cell transplant. This is decided based on two factors: 1) the patient's risk of AML coming back, and 2) if they have a matched stem cell donor available.
The research staff will also be studying how well children with Down syndrome do on the standard therapy. Down syndrome patients may respond differently to chemotherapy drugs than patients without Down syndrome. This study will give study doctors information about how Down syndrome patients respond to standard therapy.
A secondary goal of the study is to understand the biology of AML better. These tests are optional and will be done only if the patient agrees. Study doctors want to test blood or bone marrow for certain genetic changes in leukemia cells. This would help them to learn more about AML and how to treat patients better. They also want to look for very small amounts of leukemia. This is called minimal residual disease (MRD). Researchers want to find out if measuring MRD can be used in the future to decide how great the risk of relapse is for a person.
In summary, the goals of this study are:
1. To see if adding a new drug called gemtuzumab to the current standard AML treatment will improve the cure rate without causing more serious side effects
2. To compare the outcomes of children who have higher risk disease and receive a stem cell transplant to children who do not have higher risk disease
3. To evaluate how well children with Down syndrome (who are over four years old) do when they receive the standard chemotherapy without gemtuzumab
4. To understand the biology of AML better with the optional biology tests

A Phase I and Pharmacological Clinical Trial of 17-Allylamino-17-demethoxygeldanamycin (17-AAG) and Cytarabine (Ara-C) in Refractory (Resistent) Leukemia and Myelodysplastic Syndrome (MDS)
- Find the highest dose of the cancer drugs called 17-AAG (17-Allylamino-17-
demethoxygeldanamycin) and cytarabine that can be given in a 60-day schedule to patients with advanced cancer without causing bad side effects
- Learn about the side effects of 17-AAG and cytarabine when given together
- Learn how the body handles or processes the drugs and learn the other effects the drugs have on the body using blood and bone marrow samples
17-AAG is an investigational drug that has not been approved by the U.S. Food and Drug
Administration (FDA), or any other regulatory agency, for commercial use but is approved by the FDA for use in this research study. Cytarabine has been approved by the FDA for the treatment of acute myelogenous leukemia. This study will provide information that will allow the investigators to further study if the combination is more effective than each drug given alone.

A Pilot Study to Determine the Toxicity of the Addition of Rituximab to the Induction and Consolidation Phases and the Addition of Rasburicase to the Reduction Phase in Children with Newly Diagnosed Advanced B-Cell Leukemia/Lymphoma Treated with LMB/FAB Therapy
This study is being done to:
- Find out the effects, good and bad, of adding two new drugs, rituximab and rasburicase, to the standard chemotherapy drugs
- Find out the effects, good and bad, of rasburicase when given to see if it can lower the uric acid levels (salts found in patient's bloodstream)
- Compare the amount of cancer cells in the body before, during and after treatment
- Find out if there are proteins or genetic information (genes patients inherit from their parents) in the tumor cells that can tell researchers the best way to treat children with B-cell leukemia/lymphoma.
Non-Hodgkin lymphoma is a cancer of the lymph nodes (tissue throughout the body that filters disease germs from the blood). B-cell leukemia is cancer of the blood that develops in the bone marrow where blood cells are made. (ALL is a disease in which too many underdeveloped [not normal] infection-fighting white blood cells (blasts) crowd out the normal cells).
The first investigational drug, rituximab, is an anti-cancer drug that attaches to lymphoma cells and causes these cancer cells to die by stimulating the body's own immune system (the system that recognizes and attacks cells that are not normal body cells). Rituximab has been given safely along with standard chemotherapy to adult NHL patients.
However, rituximab has not yet been used in combination with standard chemotherapy to treat children.
The second drug given on this trial is called rasburicase. Rasburicase is a drug that lowers uric acid levels in the blood. Uric acid levels go up because of the death of the normal cells and tumor cells when the chemotherapy is given. Too much uric acid in the blood can cause the kidneys to fail. Researchers want to see if rasburicase can lower the uric acid levels, but they also need to find out what kind of side effects children may have when they take rasburicase. The standard drugs used to treat B-cell lymphoma are vincristine, prednisone and cyclophosphamide.

AALL06N1, "A Study of Neurocognitive Function in Children Treated for Acute Lymphocytic Leukemia (ALL)"
Patients are being asked to take part in this research study because they have been diagnosed with acute lymphocytic leukemia (ALL) and have agreed to be treated on a COG treatment study. In this study, the researchers want to learn more about children who are treated on the COG studies AALL0232 and AALL0434. In both these treatment studies, patients (people on the study) are randomized (randomized means assigned randomly like the flip of a coin, but it is done by a computer so no one will know what treatment the patient will receive) between two different treatment arms that compare different ways to give the chemotherapy, methotrexate. Methotrexate is given in a two month long phase of treatment called Interim Maintenance.
In this study, the research staff want to closely evaluate side effects that might be due to methotrexate. Specifically, the researchers want to learn more about possible side effects that affect the nervous system. A recent, large study of adult survivors of childhood ALL found no differences between survivors who never received radiation treatments and the general population with respect to the likelihood of being married, having a job, and having health insurance.
However, there are children who have neurologic side effects during therapy, or who have learning disabilities after therapy has ended. This study is looking at whether the use of methotrexate is likely to cause those side effects that affect the nervous system. This study will also look at whether or not the possible side effects are different with the different ways methotrexate is given.
Why Is This Study Being Done?
The study is being done to determine the effects, if any, of methotrexate, on learning skills and memory. Information gathered from previous studies is incomplete. There is currently no way of predicting who is likely to develop nervous system side effects related to the use of methotrexate, regardless of the way that methotrexate is given. Side effects are unintended or unwanted results of treatment. In addition, there is no way of predicting whether the nervous system side effects will be minor or major.
This study will also determine: 1) Whether rare, sudden side effects of leukemia therapy, such as seizures, are associated with learning difficulties; 2) Whether certain genetic traits (qualities of a person?s DNA that make the person unique) are associated with the possibility of methotrexate side effects; 3) Whether changes in the amounts of a substance that is found in the patient?s body are associated with side effects of methotrexate, and; 4) Whether or not a new imaging study, similar to an MRI, will predict who is at risk for side effects related to methotrexate.
The overall goal of this study is to evaluate the potential toxicity associated with methotrexate in more detail.

AAML0431, The Treatment of Down Syndrome Children with Acute
Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS) Under the Age of 4 Years
Parents/ Guardians are being asked to allow their child take part in this study because their child has Down syndrome (DS) and has recently been diagnosed with Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS).
AML is a cancer of the bone marrow, the spongy tissue inside large bones where blood cells are made. In AML, the bone marrow makes large numbers of immature white blood
cells called blasts. These blast cells crowd out the normal cells of the bone marrow. They may flood the bloodstream and invade vital organs such as the brain, testes, ovaries, or skin. These cancerous AML cells can sometimes form a solid tumor called a chloroma. Many patients have MDS before they get AML. MDS is a disease in which the body
makes fewer blood cells than usual. Bone marrow in MDS patients does not produce enough healthy blood cells. MDS can develop into leukemia.
What Is The Current Standard Of Treatment For This Disease?
The standard treatment for AML and MDS is to use a combination of cancer-fighting drugs called chemotherapy. Chemotherapy destroys the leukemia cells in the blood and bone marrow. The standard treatment regimen consists of two phases of therapy, called Induction and Intensification. In the Induction phase we try to remove all visible signs of leukemia and allow normal blood cells to be restored. This is called remission. Induction treatment is usually repeated for three cycles of therapy (each cycle 28 days). The next phase of treatment is called Intensification. Intensification chemotherapy is used to kill the few remaining leukemia cells that may have survived Induction. Intensification is usually three cycles of therapy, and includes high dose cytarabine (one of the chemotherapy drugs) in the last cycle. Patients with AML or MDS may also be treated with up to seven doses of cytarabine that is injected into the spinal fluid.
Why Is This Study Being Done?
Research has shown that children with DS are more likely to develop leukemia than children who do not have DS. However, they are also known to respond better to chemotherapy than children with AML who do not have DS.
The overall goal of this study is to see if we can increase the cure rate and decrease the side effects of therapy. Side effects are unintended and unwanted results of treatment. In this study, we will test the effects good and/or bad of changing the order of one of the chemotherapy treatments, high dose cytarabine (Ara-C). Subjects in this study will receive high dose cytarabine earlier in the treatment schedule than in past studies. Since DS patients do well on chemotherapy, study doctors want to see if it is possible to lower the side effects of chemotherapy without lowering the effectiveness of the treatment. Study doctors would like to know the effects good and/or bad of reducing the following chemotherapy treatments:
1) The number of treatments given in the spinal fluid (called ?intrathecal?)
2) The number of doses of daunorubicin, one of the chemotherapy drugs
A secondary goal of the study is to learn more about the biology of AML and MDS in DS patients. These tests are optional and will be done only if the parent/ guardian agree. Briefly, the biology studies will:
? Test for genetic changes in the leukemia cells, and genetic factors which might affect a patient?s likelihood of getting leukemia and outcome with treatment
? Look for very small amounts of cancer cells in the blood and bone marrow, called minimal residual disease (MRD). Researchers want to find out if measuring MRD can be used in the future to decide how great the risk of the cancer coming back is for a person and predict how a patient will do with treatment
? See what happens to high dose cytarabine (one of the chemotherapy drugs) in the body and how much of the drug remains active over an 8-hour period. These are called pharmacokinetic (PK) tests.
? Collect blood and bone marrow specimens and store them in a cell bank for future research into Down syndrome
In summary, the goals of this study are to:
1. See if changing the order of high dose cytarabine in the treatment plan has an affect on the cure rate for DS patients
2. See if lowering the number of treatments into the spinal fluid and the number of doses of daunorubicin will be as effective as standard treatment with fewer side effects
3. Understand the biology of AML and MDS better with the optional biology tests

Combination Chemotherapy and Radiation Therapy in Treating Patients With Acute Lymphoblastic Leukemia (ALL) That Has Relapsed in the Central Nervous System (CNS) or Testes
This study is being done to see if stronger chemotherapy (anti-cancer drugs) used with less radiation therapy can bring about a remission (make the cancer go away).
Patients are being asked to take part in this study because they have acute lymphoblastic leukemia (ALL). At least 18 months have passed since they were first diagnosed with ALL. The leukemia had gone away (been in remission) but now it has returned (relapsed). The leukemia returned in their central nervous system (brain and spinal cord) and the testes.
The research staff know that radiation therapy can cause long-term side effects (side effects are unintended physical reactions to the drugs that are unrelated to the reasons the drugs are being used). The researchers hope to find out if this study treatment will still make the same high rates of remission that are seen with standard treatment but cause less long-term side effects. In addition to these treatment aims, the research staff would like to use information collected on this study to answer some research questions that might help future patients. Patients can choose to be on this clinical trial without taking part in this piece of the research.
The research aims are as follows:
- See if tiny amounts of leukemia cells might be present in the bone marrow (the soft tissue in the hollow of flat bones of the body that makes new blood cells) at the time of relapse (study entry). Researchers want to know if the amount of these cells can tell the research staff how well a patient might respond to treatment.
- Look for changes in the genetic structure (DNA) of relapsed patients. The research staff want to see if genetic changes make a difference in how the patient responds to treatment and in the types of side effects the patient has while being treated.
- Look at the effects that the disease and treatment have on thinking, learning, and behavior. The research staff want to know if patients have fewer learning and other psychological problems if less CNS radiation therapy is given.

Comparison of Peripheral Blood Stem Cell Transplantation with Bone Marrow Transplantation for the Treatment of Serious Hematological Malignancies
This research study will compare the outcomes of study participants who have had peripheral blood stem cell transplantation from unrelated donors with those who have had bone marrow transplant from unrelated donors for the treatment of serious hematological malignancies.
Two types of stem cell transplantation have been used to treat patients with certain types of serious diseases. Stem cells can be obtained from bone marrow or from circulating blood (peripheral blood stem cells). Participants may be treated with a transplant of either bone marrow or peripheral blood stem cells (PBSC) from unrelated donors.
Both of these types of transplant have been successful for the treatment of leukemia and myelodysplasia. The goal of this research study is to see if there are better results using a bone marrow transplant or a PBSC transplant from unrelated donors.

Farnesyl Transferase Inhibitor R115777 in Acute Myeloid Leukemia (AML) Patients in Second or Subsequent Remission or in Remission after Primary Induction Failure or Patients over Age 60 in First Remission
This research study is being done to determine how well the investigational drug called farnesyl transferase inhibitor (FTI) R115777 can keep your cancer in remission (when the disease is less active) and to see what side effects (good and bad) the drug causes.
This research is being done because the average time of remission without treatment is 4 months. Even though you are currently in remission, there remains a great chance that your leukemia will come back despite the treatment that you have received. There is currently no effective additional treatment to keep your cancer in remission.

Genetic Epidemiology of B-Cell Lymphoproliferative Disorders
The major purpose of this research study is to understand how genetic and environmental exposures contribute to the development of blood or lymph node cancer. This study will improve our understanding of what causes blood or lymph node cancers.
In addition, we hope this study will lead to ways to detect such cancers early, and perhaps, even to prevent them. Patients are asked to participate because either they or a family member is known or thought to have blood or lymph node cancer. There is some evidence that a personal or family history or environmental exposures may increase a person's chances of having a blood or lymph node cancer.

Genetic Epidemiology of Chronic Lymphocytic Leukemia (CLL)
Research has consistently shown that patients with at least one blood relative with chronic lymphocytic leukemia (CLL) have over two times greater risk of getting CLL compared to the general population. These findings strongly suggest that genetics play a role in the development of CLL. As such, the purpose of this study is to identify the genes that increase the risk of developing CLL. To do this, we need families that have multiple individuals diagnosed with CLL, i.e., CLL families. CLL families are a very valuable resource that will enable us to better understand the genetic basis of this cancer. Because CLL families are rare, we have formed a U.S. collaboration to identify these families, known as the Genetic Epidemiology of CLL (GEC) Consortium. This consortium is funded by the National Cancer Institute and includes investigators from Mayo Clinic, M.D. Anderson Cancer Center, National Cancer Institute, UCSD, and University of Minnesota. The completion of this study will advance our understanding of how CLL develops and should ultimately help identify new approaches for the prevention of CLL.

Intensive Treatment for Intermediate-Risk Relapse of
Childhood B-Precursor Acute Lymphoblastic Leukemia (ALL): A Randomized Trial of Vincristine Strategies
Patients have been treated in the past for a cancer of the blood cells called acute lymphoblastic leukemia (ALL). Patients are being asked to take part in this study because the leukemia has come back (relapsed) and is of intermediate risk. The term "risk" refers to the chance of the cancer coming back again after treatment for this relapse. The patient's leukemia is defined as "intermediate risk" because one of the following apply:
-The leukemia returned in their bone marrow (with or without leukemia in
other parts of their body) 3 years or more after they were first diagnosed
with ALL.
-The leukemia returned in the patient's central nervous system (spinal fluid) and/or the testes (but not in the bone marrow) less than 18 months after they were first diagnosed with ALL.
It is common to enroll children and adolescents with cancer in a clinical trial that seeks to
improve cancer treatment over time. Clinical trials include only people who choose to
take part. Many different chemotherapy treatment programs have been used for children with intermediate risk relapse of ALL, and there is no real standard treatment at this time. Patients have a choice between other treatments for ALL and this clinical trial.
What Is The Current Standard Of Treatment For This Disease?
There is no generally accepted standard treatment for intermediate risk relapse of ALL at this time. Combination chemotherapy has been the main treatment for children with intermediate risk relapsed ALL. Several studies have used various combinations and had similar outcomes in the number of children treated successfully.
The first month of treatment usually involves chemotherapy very similar to that given to treat ALL for the first time. Children with intermediate risk relapse have an excellent chance of going into a second remission (disappearance of all signs and symptoms of ALL).
However, the risk that the leukemia will come back after getting into remission is definitely higher than it was when the patient was first diagnosed with ALL. Because of this, the treatment that is given for relapse is more intensive (stronger) than that given to treat ALL for the first time. Like the first treatment for ALL, treatment for intermediate risk relapse has several phases. All phases of treatment are very important. The total length of chemotherapy treatment used for intermediate risk relapse varies from about 1.5 to 2.5 years in most cases.
Some doctors also recommend bone marrow (stem cell) transplants for some children and adolescents with intermediate risk relapse. This study will recommend bone marrow transplant for children with intermediate risk relapse that go into a second remission and have a matched family donor. About 20 to 30 percent of patients will have a close match. This use of bone marrow transplant is considered to be a valid treatment. Also, radiation therapy is sometimes used in relapsed ALL, especially if the relapse involves organs such as the brain or testes.
Why Is This Study Being Done?
Since there is no standard treatment regimen for children with intermediate risk relapse of ALL, the major goal of this study is to establish an effective therapy. The study treatment plan is based on an earlier plan (?POG 9412?) which showed a good effect in children who had a relapse of ALL in the brain. In this study, the treatment will be strengthened by giving higher doses of chemotherapy drugs more often. This study is to determine how effective this treatment is for all types of intermediate risk relapse.
Patients received vincristine during their first treatment for ALL, and it is part of treatments commonly used for relapsed ALL. The standard dose of vincristine is 1.5 milligrams/square meter (mg/m2)with a maximum dose of 2 mg. Higher doses of vincristine have been used to treat children with other forms of cancer and a recent Dutch trial has also used a higher dose to treat children with ALL. The researchers want to see if a higher dose of vincristine (2 mg/m2 with a maximum dose of 2.5 mg) can get rid of the cancer for as long as possible in more patients with relapsed ALL.
Researchers want to compare the effects, good and/or bad, of chemotherapy with a high dose of vincristine against chemotherapy with a standard dose of vincristine. The research staff want to find out which dose is better. In this study, patients will get either the high dose of vincristine or the standard dose of vincristine. Patients will not get both.
The goals of this study are:
1) To find out the effectiveness and side effects of the high dose combination chemotherapy treatment for all patients on this study.
2) To find out the effectiveness and side effects of higher dose vincristine compared to standard dose vincristine.
In addition to the treatment goals, researchers would like to use specimens collected on this study to answer some research questions that might benefit future patients. Patients can choose to be in this clinical trial without taking part in this research portion.
One of the biology research goals involves a test to measure minimal residual disease (MRD). This test measures numbers of leukemia cells that are too small to be counted using traditional methods. Researchers will use it to find out if leukemia is still present in the bone marrow. The research staff also want to study the genetic make-up of the cancer cells to try to learn about why people get cancer and if the genes in the cancer cells can predict how someone will respond to treatment.
Biology Research Goals (Optional Participation):
1) To find out if MRD levels can be used to tell how well a patient with relapsed ALL is responding to treatment. Researchers also want to find out if high MRD levels can be used to identify people at higher risk of another relapse.
2) To study genetic changes, and patterns within the genes of the leukemia cells. The research staff hope to learn more about disease resistance and find out if they can predict how well someone will respond to chemotherapy.
3) To find out if a) differences that occur naturally in genes (polymorphisms) might be part of the reason why some people develop leukemia and b) if those differences influence why some patients have certain side effects with treatment.

MC0784, Phase II Trial of Pentostatin, Cyclophosphamide, and Rituximab (Rituxan) followed by Consolidation with Lenalidomide (Revlimid) for Previously Untreated B-Cell Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)
Patients are being asked to take part in this research study because they have previously untreated B-cell Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). This study is being done to learn about the effectiveness and side effects of pentostatin, cyclophosphamide and rituximab (PCR) followed by lenalidomide for previously untreated CLL/SLL and to learn whether lenalidomide treatment after treatment with PCR can eliminate residual CLL/SLL that remains after PCR.

Phase 2 Study of the Subcutaneous Administration of Homoharringtonine (CGX-635) in the Treatment of Patients with Chronic Myeloid Leukemia (CML) with the T315I BCR-ABL Gene Mutation
Patients are asked to take part in this research study because they have chronic myeloid leukemia (CML) and a mutation (change) in a particular gene (T315I gene) found in their bone marrow and blood cells. CML is a blood disorder related to high white blood cell counts and platelet counts, anemia (decreased red blood cells), bleeding problems or bruising (due to low platelet counts, which circulate in the blood and prevent bleeding), fatigue (tiredness) and increased risk of infection. The T315I gene mutation occurs in a small number of patients with CML. Because of this mutation, patients may not respond to some treatments for CML. The purpose of this clinical research study is to determine the safety of the investigational drug homoharringtonine (HHT) and its potential effectiveness for the treatment of CML in patients who have the T315I mutation.
The drug used in this study is considered investigational, which means it has either not been approved by the U.S. Food and Drug Administration (FDA) for routine clinical use or for the use described in this study. However the FDA has allowed the use of this drug/device in this research study.

Phase II Study with Azacitidine with or without (the Histone Deacetylase Inhibitor) MS-275 for the Treatment of Myelodysplastic Syndrome (MDS), Chronic Myelomonocytic Leukemia (CML) and Acute Myeloid Leukemia (AML)
The purpose of this study is to find out what effects, good or bad, one of two treatment programs has on a patient and their bone marrow disorder. One treatment program consists of a new dose and schedule of a drug called Azacitidine, which is approved for the treatment of myelodysplastic syndrome (MDS). The other treatment program includes the same dose and schedule of azacitidine in combination with a new drug known as MS-275. In this study patients will get either azacitidine alone, or azacitidine plus MS-275. Patients will not get both treatment
programs.
MS-275 is investigational and has not been approved by the U.S. Food and Drug Administration (FDA) for use in this cancer.

Treatment Study for Patients Diagnosed with High Risk B-Precursor Acute Lymphoblastic Leukemia (ALL)
Leukemia is cancer of the blood. It starts in the bone marrow, which is the soft, spongy center of the long bones that makes the three major blood cells: white blood cells to fight infection; red blood cells that carry oxygen; and platelets that help blood clot and stop bleeding. Acute lymphoblastic leukemia (ALL) is a disease in which too many underdeveloped (not normal) infection-fighting white blood cells called "blasts", are found in the blood and bone marrow. These blasts crowd out the normal cells and can be found in the brain, spinal cord, and/or other organs of the body.
ALL is said to be "high risk" because patients have a white blood cell count of over 50,000 and/or they are ten years of age or older. Patients are also classified as "high risk' if any of the following applies:
- They are a male and have leukemia in their testes, regardless of their age and/or white blood cell count
- Patient has gotten treatment with steroid medicines, such as prednisone or decadron, in the month before they were diagnosed with leukemia
This study is being done to see if we can increase the cure rate of high risk ALL without increasing the side effects (unintended and unwanted results) of treatment.
The rate of survival keeps getting better for children and adolescents with high risk ALL. However, leukemia in the central nervous system (CNS) (brain and spinal cord) has become an increasing cause of treatment failure. This study will use an established chemotherapy regimen that has been very effective for treating children and adolescents with high risk ALL and will test if two different changes to this treatment can cure more patients.
Goal #1: To find out if using dexamethasone instead of prednisone during the first month of treatment can improve survival rates without causing more bad side effects. Prednisone and dexamethasone are closely related medicines called "steroids." In previous studies, steroids have been shown to be very effective against ALL, especially when given early in treatment. The standard treatment in high risk ALL is to give prednisone every day for 28 days during the first month of treatment.
When dexamethasone was used for all 28 days of the first month of treatment in many recent U.S. trials for children and adolescents with high risk ALL, there was a higher risk of infection. This included major life-threatening infections.
Because of this, the study will test two things:
- If 14 days of dexamethasone, instead of 28, can be taken without a higher number of bad side effects, and
- If 14 days of dexamethasone will be better than 28 days of prednisone in lowering the number of leukemia cells during the first month of treatment.
Goal#2: To find out if using high doses of methotrexate instead of using lower doses of
methotrexate on a schedule that gradually increases the dose, will keep the cancer from coming back without having more bad side effects.
Methotrexate is a cancer-fighting drug that is very important in the treatment of leukemia.
There are two different ways to give methotrexate during the interim maintenance stage of treatment. We know that both of these ways of giving methotrexate have been very effective in treating ALL, but they have never been directly compared to one another in children and adolescents with high risk ALL.
In"high dose" methotrexate treatment, the same dose of methotrexate is given a total of four times (every two weeks over a nine-week period).
In Capizzi methotrexate, methotrexate is given a total of five times (every 10 days over an eight-week period). Instead of being the same dose (as in high dose methotrexate treatment), Capizzi methotrexate is given at a lower dose the first time, and the amount of the dose slowly increases with each of the later doses. Capizzi methotrexate also includes treatment of another medicine, call PEG-asparaginase, which is given twice during this eight-week stage of treatment.
In addition to the goals related to the changes in treatment, there is an additional research
goal.
Goal#3: To see how quickly patients are helped by the induction phase (reach disease remission) and how well they do after treatment, as measured by the presence or absence of very small numbers of leukemia cells in the bone marrow after the first month of treatment.
