Filter by:In this study researchers propose to do a chart review of all patients that are treated outside of a clinical trial with imatinib, dasatinib, nilotinib, or any other tyrosine kinase inhibitor that becomes FDA approved for the managements of CML that come to MDACC for a second opinion. This is an important population of patients that differs in their management from patients treated in clinical trials for several reasons including but not limited to: 1. It represents a very large patient population receiving standard-dose therapy with TKI. We estimate that we have evaluated over 300 patients that fall in this category. 2. The follow-up for patients in the largest trial using standard-dose imatinib (the IRIS trial, with 553 patients in treated with imatinib) has been limited after the first 12 months. For example, the rate of molecular responses after the first 12 months of therapy was not obtained as samples stopped being collected at that time point. 3. Registration studies for dasatinib and nilotinib have similar limitations with limited follow-up and available information coming only from databases from the sponsors to which there is limited access to investigate dosing, chronic toxicities, second malignancies and other important aspects of therapy. 4. Patients who are or become pregnant during therapy with TKI have not been eligible for clinical trials with TKI or had to be taken off study. Thus, there is no information on the effect of TKI on imatinib on pregnancy and conception. We have followed several such patients at MDACC. 5. This is a patient population that follows therapy mostly as directed by their local oncologists. This is frequently less stringently adhered to the recommended guidelines for TKI therapy, with more frequent treatment interruptions, and frequently using suboptimal doses of imatinib (i.e., less than 300mg daily). The effect of these treatment interruptions and suboptimal dosing on response and development of resistance is unclear. Researchers plan to conduct a chart review of these patients to study their treatment course before their initial evaluation at MDACC, and between and during visits to MDACC.
This is a two-part safety and efficacy study of SKI-606 in subjects who have Philadelphia chromosome positive leukemias (CML). Part 1 will be a dose-escalation study, in which an escalating dose of SKI-606 (Bosutinib), up to 600 mg, will be studied in subjects with imatinib resistant/refractory or imatinib intolerant chronic phase CML. Part 2 will evaluate the safety and efficacy of the maximum tolerated dose (MTD) of SKI-606 (Bosutinib)identified in Part 1 of the study.
The purpose of this study is to determine the maximum tolerated dose (MTD) of TAK-901 in subjects with advanced hematological malignancies, and to further assess the safety and tolerability of TAK-901 at or below the MTD in an expanded cohort of subjects in order to select a dose for future studies.
There is no available data on the clinical benefit of dose escalation for patients with suboptimal response to imatinib, and patients may still improve their response with continuation of therapy at the standard dose as shown in the IRIS trial after 5 years of follow-up. However, there is no data yet regarding the potential benefit of using nilotinib in the group of patients with suboptimal response. In this study, the efficacy of nilotinib 400mg BID will be compared to imatinib 600mg QD.
The primary goal of this study is to determine the rate of confirmed best cumulative complete molecular response within the first year of study therapy with imatinib or nilotinib. The study will also explore the impact and significance of the achieved CMR on patient outcomes (PFS, EFS and OS), characterize the kinetics of CMR achieved in both treatment arms and after the cross-over.
The traditional way of doing a donor transplant is to give high doses of chemotherapy and radiation before giving the stem cells. However, high doses of chemotherapy and radiation can have serious side-effects. The doctors think that the transplant will be safer and more likely to be successful with reduced doses of chemotherapy and radiation. The purpose of this study is to find out how good a combination of chemotherapy and radiation at reduced doses followed by a cord blood transplant are at treating cancer. The stem cells chosen for the transplant are from umbilical cord blood. Umbilical cord blood is collected from healthy newborn babies and frozen. One cord blood collection is called a "cord blood unit." On transplant day, the cord blood will be given through the catheter just like a blood transfusion. Transplants done this way have been successful. However, this type of transplant is fairly new. Therefore, it is important to study it so the doctors can better understand how it works. Most blood or bone marrow transplants using donor stem cells are done as part of a study. When patients are on a study we test new ways of treating them which we think may be better than the old ways. We collect information about the result of this treatment so we can understand how well the treatment works. This is so we can learn better ways to treat our patients.
This phase II trial is studying how well umbilical cord blood transplant from a donor works in treating patients with hematological cancer. Giving chemotherapy and total-body irradiation (TBI) before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from an unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening.
This study consists of two phases: the first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with advanced myeloid malignancies; the second portion of the study is a Phase 2 study to define the efficacy and safety profile of single-agent SB1518 at the recommended dose in subjects with chronic idiopathic myelofibrosis (CIMF).
One of two different doses of thymoglobulin will allow bone marrow engraftment with minimal Graft-versus-Host Disease and allow adequate immune response to allow the transplanted stem cells to replace the tumor cells.
The prognosis of pediatric patients with hematologic malignancies whose disease is primarily refractory or those who experience a chemotherapy resistant bone marrow relapse is extremely poor. When new agents or chemotherapeutic regimens are unable to induce remission in this patient population, hematopoietic stem cell transplant (HSCT) is also a poor alternative. Thus, in this very high risk group, additional attempts at remission induction with various combinations of chemotherapy alone will unlikely improve outcome and will contribute to overall toxicity. Alternative therapies are needed in these patients with chemotherapy resistant disease. Immunotherapy with natural killer (NK) cell infusion has the potential to decrease toxicity and induce hematologic remission. NK cells can kill target cells, including leukemia cells, without prior exposure to those cells. In patients undergoing allogeneic HSCT, several studies have demonstrated the powerful effect of NK cells against leukemia. Furthermore, NK cell infusions in patients with primary refractory or multiple-relapsed leukemia have been shown to be well tolerated and void of graft-versus-host disease effects. In this high risk group, complete leukemic remission has been observed in several of these patients after NK cell infusion. With the current technology available at St. Jude, we have developed a procedure to purify NK cells from adult donors. This protocol will assess the safety of chemotherapy and IL-2 administration to facilitate transient NK-cell engraftment in research participants who have chemotherapy refractory hematologic malignancies including acute lymphoblastic leukemia, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, myelodysplastic syndrome, or non-Hodgkin's lymphoma. In this same cohort, we will also intend to explore the efficacy of NK cells infused in those participants who have chemotherapy refractory disease.
