Cyclophosphamide Treatment Options in Texas

The goal of this clinical research study is to compare carboplatin to cyclophosphamide when given with etoposide, vincristine, and radiation therapy in the treatment of choroid plexus tumors. The safety of these 2 combination therapies will also be compared. Objectives: OVERALL AIM: To improve choroid plexus tumor treatment through better understanding of the tumor biology and through increased knowledge about the benefit of specific treatment elements. Specific Objectives: The study will have a prephase to evaluate the feasibility of the following randomized study (main phase). Pre-Phase (completed 2005) Primary Specific Objective: To determine the number of patients accountable per year for randomization in a worldwide study. Secondary Specific Objective: To measure the number of drop outs and to describe the toxicity of the chemotherapy. Main Phase (started in 2006) Primary Specific Objective: To compare the survival times after cyclophosphamide based treatment with the survival times after carboplatin based treatment in choroid plexus tumor patients. Main Phase Secondary Specific Objectives: 1. To compare the resectability of choroid plexus tumors after two blocks of cyclophosphamide based treatment with the resectability after two blocks of carboplatin based treatment. 2. To compare response rates of incompletely resected choroid plexus tumors to two blocks of cyclophosphamide based treatment with the response rates after two blocks of carboplatin based treatment. 3. To determine the prognostic relevance of histological atypia and SV40 in choroid plexus tumors. Read Less

This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.

This is a Phase Ib, open-label, two-stage study with two active regimens in each stage designed to evaluate the safety and tolerability of combination treatment with atezolizumab, trastuzumab, and pertuzumab (with and without docetaxel) or atezolizumab and trastuzumab emtansine in participants with human epidermal growth factor receptor 2 (HER2) positive metastatic breast cancer (MBC) and locally advanced early breast cancer (EBC), and atezolizumab with doxorubicin and cyclophosphamide in HER2-negative breast cancer.

Determine whether viagenpumatucel-L combined with low-dose cyclophosphamide prolongs survival in patients with NSCLC who failed 2 or 3 prior lines of therapy for incurable or metastatic disease compared with chemotherapy alone. Read Less

This is a phase 1, open-label, multicenter, ascending-dose escalation study of cemiplimab, alone and in combination with other anti-cancer therapies in patients with advanced malignancies. Read Less

Objectives: 1. To determine if dose intensive Vincristine, Doxorubicin, Cyclophosphamide and Dexrazoxane (VACdxr) with or without ImmTherTM can improve the 2-year disease-free survival seen with standard VAC therapy. 2. To evaluate the feasibility and describe the toxicity associated with VACdxr. 3. To evaluate the feasibility and describe the toxicity of administering ImmTherTM on a weekly basis for 50- 52 weeks. 4. To determine which therapy (VACdxr+ or VACdxr-) is worthy of further evaluation. Read Less

Participants in this study have a hematologic malignancy which is a disorder in the bone marrow that affects the body's ability to create blood. Participants might benefit from receiving an allogeneic stem cell transplant (meaning the cells come from a donor). The participants donor is a family member. Stem cells are cells in the bone marrow and blood that can form a whole new blood system. Read Less

Systemic Sclerosis is a disease that may be caused by the immune system reacting against skin and certain organs. It is possible, that by changing the immune system we can modify the progression of this disease. Stem cells are created in the bone marrow. They mature into different types of blood cells that are needed including red blood cells, white blood cells, and platelets. In this study, we will stimulate the bone marrow to make extra stem cells. Next we will collect the stem cells, select specific cells, and store them. We will then give high dose chemotherapy that will destroy the patients immune system. We will then give back the selected stem cells we collected. We believe that these selected stem cells may be able to "re-create" the immune system without the portion that causes Systemic Sclerosis. The purpose of this study is to try to discover if stem cell transplantation can help patients with Systemic Sclerosis. We will also try to learn what the side effects are of this treatment in patients with Systemic Sclerosis. We hope that this treatment will help to relieve the symptoms patients are experiencing, although we do not know if it will. Read Less

RATIONALE: Drugs used in chemotherapy, such as vincristine, irinotecan, ifosfamide, etoposide, doxorubicin, cyclophosphamide, and dactinomycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving high-dose combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase III trial is studying how well giving high-dose combination chemotherapy together with radiation therapy works in treating patients with newly diagnosed metastatic rhabdomyosarcoma or ectomesenchymoma.

The major goal of this study is to determine the risks and benefits of bone marrow transplants in patients with severe thalassemia or sickle cell disease. Participation in this project will be for two years. Read Less

Subjects are being asked to participate in this study because treatment of their disease requires them to receive a stem cell transplant. Stem cells or "mother" cells are the source of normal blood cells and lead to recovery of blood counts after bone marrow transplantation (BMT). Unfortunately, there is not a perfectly matched stem cell donor (like a sister or brother) and the subject's disease is considered rapidly progressive and does not permit enough time to identify another donor (like someone from a registry list that is not their relative). We have, however, identified a close relative of the subject's whose stem cells are not a perfect match, but can be used. However, with this type of donor, there is typically an increased risk of developing graft-versus-host disease (GVHD), a high rate of transplant failure, and a longer delay in the recovery of the immune system. GVHD is a serious and sometimes fatal side effect of stem cell transplant. GVHD occurs when the new donor cells (graft) recognizes that the body tissues of the patient (host) are different from those of the donor. When this happens, cells in the graft may attack the host organs, primarily the skin, liver, and intestines. The number of occurrences and harshness of severe GVHD depends on several factors, including the degree of genetic differences between the donor and recipient, the intensity of the pre-treatment conditioning regimen, the quantity of transplanted cells, and the recipient's age. In recipients of mismatched family member or matched unrelated donor stem cell transplants, there is a greater risk of GVHD so that 70-90% of recipients of unchanged marrow will develop severe GVHD which could include symptoms such as marked diarrhea, liver failure, or even death. In an effort to lower the occurrences and severity of graft-versus-host disease in patients and to lower the rate of transplant failure, we would like to specially treat the donor's blood cells to remove cells that are most likely to attack the patient's tissues. This will occur in combination with intense conditioning treatment that the patient will receive before the transplant. Read Less

Multiple Sclerosis is a disease that may be caused by the immune system reacting against the nervous system. It is possible, that by changing the immune system we can modify the progression of this disease. In this study, we will try to learn whether treatment with a bone marrow transplant (BMT) can help patients with multiple sclerosis. We will also try to learn what the side effects are of this treatment in patients with multiple sclerosis. Read Less
