This trial is active, not recruiting.
|Treatments||ofatumumab, ifosfamide, etoposide, mesna, g-csf, stem cell collection|
|Sponsor||M.D. Anderson Cancer Center|
|Start date||August 2011|
|End date||August 2018|
|Trial size||50 participants|
|Trial identifier||NCT01329900, 2009-0796, NCI-2011-01068|
The goal of this clinical research study is to learn if it is possible to collect stem cells after ofatumumab and chemotherapy treatment. This study will also evaluate side-effects, number of stem cells collected, and the number of procedures that are needed to collect enough stem cells.
|Intervention model||single group assignment|
time frame: Mobilization rate measured on Day 21
All participants from 18 years up to 70 years old.
Inclusion Criteria: 1. Patients with histologically confirmed CD20 positive B-cell NHL who are candidates for autologous SCT. 2. Patients must have PR to salvage chemotherapy. 3. Age 18-70 years. 4. Platelet count >/= 100,00 mm³ independent of transfusion support. 5. Absolute neutrophil count >/= 1500/mm³. 6. Zubrod performance status (PS) 2 or less. 7. Negative serum pregnancy test in women of childbearing potential. This is a female who has not been postmenopausal for at least 12 consecutive months or who has not undergone previous surgical sterilization. 8. Less than 5% marrow involvement with NHL within 4 weeks of study as defined by unilateral bone marrow aspiration and biopsy. 9. Seronegativity for HIV, HTLV1, Hepatitis . Exclusion Criteria: 1. Subjects who have current active hepatic ( (HbsAg, HbcAb, and positive viral load by PCR) or biliary disease (with exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases or stable chronic liver disease per investigator assessment) with ALT > 2x upper limit of normal or bilirubin > 1.5.

|Description||The Study Drugs: Ofatumumab is a human monoclonal antibody for the CD20 protein designed to bind to the surface of some of the white blood cells (B-cells). It can destroy cancer cells that come from B-cells, and can be used to treat cancers of B-cells such as resistant CLL (chronic lymphocytic leukemia). Etoposide is designed to slow or stop the growth of cancer cells. Filgrastim promotes the growth of white blood cells, which help to fight infections. Ifosfamide is designed to slow or stop the growth of cancer cells. Mesna is a drug that protects bladder cells from damage by the chemotherapy drug ifosfamide. It is used to decrease the risk of bleeding in the bladder. Treatment Administration: You will be admitted to the hospital. You will have to stay in the hospital for 4-6 days for this part of the treatment. On Day 1, you will receive ofatumumab through the CVL over 6-8 hours. On Days 2, 3, and 4, you will receive ifosfamide and mesna continuously and etoposide every 12 hours. Mesna is given to help decrease the risk of developing side effects. As an outpatient, you will receive a higher dose of ofatumumab (about 1 week after the first one) through the CVL over 10-12 hours. Beginning on Day 6, you will get G-CSF (filgrastim) injections (given under the skin) and will continue to be given until enough stem cells have been collected. Tests and Procedures: Every day while you are in the hospital, you will have a physical exam and you will be asked about any side effects you may be having. After you are no longer in the hospital, you will have a physical exam and you will be asked about any side effects you may be having when the doctor thinks it is needed. While you are waiting for enough stem cells to be collected, you will have blood drawn (about 1 tablespoon) for routine tests at least 3 times a week. If your doctor thinks it is needed, you may have blood drawn more often. Stem Cell Collection: Blood stem cells will be collected when your blood counts have returned to normal (about 10-16 days after chemotherapy). The process of stem cell collection takes about 4 hours each time. You will have stem cells collected each day until enough are collected (between 1-6 sessions). A machine is attached to the CVL and blood is withdrawn. The blood then flows through the machine, which removes stem cells from the blood. The blood is then returned back to you through the CVL. The stem cells are then frozen and stored. These stem cells will be given back to you after the next phase of treatment to help your blood counts recover after high dose chemotherapy. After enough stem cells have been collected, you will be admitted to the hospital for high dose chemotherapy. You will sign a separate consent before you receive high dose chemotherapy. During the stem cell collection, blood (about 2 teaspoons) will be drawn through the CVL to check for cell markers that can affect the response of the cell counts and to check the status of the disease. Length of Study: Patients will be followed for up to 12 months after the transplant. You will be taken off study early if the stem cell collection does not work. This is an investigational study. Etoposide and ifosfamide are FDA approved and are commercially available for lymphomas. Ofatumumab has been approved by the FDA for treatment of recurrent refractory chronic lymphocytic leukemias. G-CSF and Mesna are FDA approved and commercially available. The use of Ofatumumab for the collection of stem cells is investigational. Up to 50 patients will take part in this study. All will be enrolled at MD Anderson.|
