129 Clinical Trials for Various Conditions
This is a single-arm, open label, phase 2 study to determine the safety and efficacy of vorinostat without serotherapy as GVHD prophylaxis when combined with either tacrolimus and methotrexate or post-transplant cyclophosphamide, tacrolimus, and mycophenolate in patients aged 1 to 26 years of age with non-malignant disorders undergoing bone marrow transplant following myeloablative conditioning.
This Phase 2, single-arm, open-label study aims to evaluate the safety and efficacy of low-dose (25 mg/kg) post-transplant cyclophosphamide (PTCy) for prophylaxis of Graft-versus-Host Disease (GVHD) in patients undergoing allogeneic stem cell transplantation following reduced-intensity or non-myeloablative conditioning. The study will focus on matched sibling, matched unrelated, and haploidentical peripheral blood stem cell donors. The primary endpoint is 1-year GVHD-Free Relapse-Free Survival (GRFS). The study seeks to determine if low-dose PTCy offers similar outcomes as higher doses, with potentially reduced toxicity.
This study will compare post-transplant health-related quality of life following the use of standard versus attenuated dose of post-transplant cyclophosphamide in addition to two-drug graft-versus-host disease (GVHD) prophylaxis among recipients of allogeneic hematopoietic stem cell transplant.
This is an open-label phase 2 study designed to explore the efficacy and safety of low-dose PTCy-ruxolitinib GVHD prophylaxis in older adults undergoing allogeneic HCT with a matched sibling or unrelated donor with a peripheral blood stem cell graft.
Background: People living with HIV(PLWH) are at a higher risk for cancers that may be curable with a bone marrow transplant. HIV infection itself is no longer a reason to not get a transplant, for patients who otherwise have a standard reason to need transplant. Objective: This study is being done to see if a new combination of drugs (cyclophosphamide, maraviroc, and bortezomib) is both safe and effective at protecting against graft-versus-host disease after bone marrow transplant. The study will also test the transplant s impact on your survival and control of your cancer. Eligibility: People aged 18 years and older living with HIV and a blood cancer that is eligible for a transplant. Healthy family members aged 12 or older who are half matched to transplant recipients are also needed to donate bone marrow. Design: The study will be done in 2 phases. The first phase will be to see if we can safely use a new combination of drugs to prevent GVHD. If the combination is safe in the first phase, the study will proceed to the second phase. In the second phase, we will see if this new combination can better protect against GVHD after transplant. Participants will be screened. Their diagnoses, organ function and eligibility will be confirmed. Participants will have a catheter inserted into a vein in their chest or neck. Medications and transfusions will be given through the catheter; blood will be drawn from it. Participants will be in the hospital for 6 weeks or longer. They will receive various drugs for 2 weeks to prep their body for the transplant. The transplant cells will be administered through the catheter. Participants will continue to receive drug treatments after the transplant. Blood transfusions may also be needed. Participants will return 1-2 times per week for follow-up visits for 3 months after discharge. Participants will have visits 6, 12, 18, 24 months after transplant, then once a year for 5 years.
Background: Blood cancers (such as leukemias or lymphomas) often do not respond to standard treatments. A transplant of blood stem cells from a healthy donor can help people with these cancers. Sometimes these transplants cause serious side effects, including a common immunologic problem called graft-versus-host disease. A drug called cyclophosphamide given early after the transplant (post-transplantation cyclophosphamide, PTCy) can reduce these complications. But sometimes this drug has its own negative effects. Furthermore, studies in mice suggest that an intermediate, rather than very high, dose of this drug may best protect against graft-versus-host disease. Objective: To find out if a lower dose of PTCy is more helpful for people who undergo blood stem cell transplants. Eligibility: People aged 18 and older who have a blood cancer and are eligible for a transplant of blood stem cells from another person. Healthy donors are also needed but must be related to the individual needing the transplant. Design: Participants will undergo screening. Transplant recipients will have imaging scans and tests of their heart and lung function. They will be assessed for the status of their cancer, including bone marrow taken from their pelvis and possibly also scans and/or fluid drawn from the spine depending on the disease type. Donors will be screened for general health. They will give several tubes of blood. They will give an oral swab and saliva and stool samples for research. Recipients will be in the hospital at least 4 to 6 weeks. They will have a temporary catheter inserted into a vein in the chest or neck. Medications will be given and blood will be drawn through the catheter. The transplanted stem cells will be given through the catheter. Participants will receive medications both before and after the transplant. Participants will return to the clinic at least once a week for 3 months after leaving the hospital. Follow-up visits will continue periodically for 5 years.
This is a pilot study to evaluate the feasibility, safety and potential benefits of removing one immune suppressive drug called mycophenolate mofetil (MMF) from the standard allogenic stem cell transplant treatment protocol. MMF will be omitted from the transplant regimen in 60 eligible patients with hematologic malignancies. Participants will be followed for up to 2 years post standard of care transplant at Cedars-Sinai.
So this a Phase I study with primary objective to determine the feasibility and safety of combining post-transplant cyclophosphamide and urinary-derived human chorionic gonadotropin and epidermal growth factor (uhCG/EGF) as graft versus host disease prophylaxis in stem cell transplant with MMUDs Secondary objectives are to determine the incidence acute and chronic GVHD, progression-free survival , and overall survival
This is a single arm, open label, optimal 2-stage Simon design phase Ib-II clinical trial. Adult patients with hematological malignancies undergoing allogeneic HSCT from first- or second-degree haploidentical donor are eligible for the study if they meet the standard criteria defined in our institutional standard operation procedures (SOPs), meet all inclusion criteria, and do not satisfy any exclusion criteria. Patients will receive non-myeloablative, reduced-intensity or myeloablative conditioning regimen followed by peripheral blood hematopoietic stem cells. Patients will receive cyclophosphamide, abatacept, and short-duration tacrolimus for GvHD prophylaxis.
This is a multicenter randomized, double blind, Phase 2 trial for patients receiving transplants from 7 of 8 HLA matched donors, in which an extended dosing regimen of abatacept, and a short-term dosing regimen + placebo, when added to standard calcineurin inhibitor + methotrexate-based prophylaxis, will be compared for their ability to improve outcomes in patients with a minimum follow-up of one year post-transplant. All patients will receive 4 doses of abatacept (Days -1, +5, +14, +28). Prior to the fifth dose, patients will be randomly assigned to the 4-dose abatacept arm and receive 4 doses of placebo or 8-dose abatacept arm and receive 4 more doses of abatacept. The primary endpoint of the study will be severe AGVHD-free, severe CGVHD-free, relapse-free survival (SGRFS). The study will end when the last patient has reached 2 years after transplant. Results will first be calculated and the study unblinded when the last patient has reached one year post-transplant.
The purpose of this study is to determine the recommended phase 2 dose of the drug Vorinostat in children, adolescents and young adults following allogeneic blood or marrow transplant (BMT) and determine whether the addition of Vorinostat to the standard graft versus host disease (GVHD) prophylaxis will reduce the incidence of GVHD.
This research study is studying the removal of a subset of white blood cells (called alpha/beta T cells) from the donor product using a cell separation device before the product is transplanted into the participant. The device used to remove the α/βT cells in this study is: -CliniMACS® TCR α/β Reagent System
To assess the tolerability of the costimulation blocking agent abatacept (CTLA4-Ig) when added to the standard graft versus host disease (GVHD) prophylaxis regimen of a calcineurin inhibitor and methotrexate in patients receiving early alemtuzumab followed by fludarabine, thiotepa, melphalan, and alemtuzumab for conditioning.
Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant. T-cells are white blood cells that are important to the immune system. The T cells for this study (called regulatory T-cells, or Tregs) will be from a donor who is not related to you. Before the Tregs are given to you, they may be changed in the laboratory to make use of sugar that is found in small amounts in blood cells through a process called fucosylation. They are then called fucosylated Tregs. Adding more sugars to the Tregs in the laboratory is designed to help the Tregs find their way faster to the bone marrow, which may help low blood counts to recover faster. The goal of this clinical research study is to learn if it is safe and practical to give fucosylated Tregs to patients who will receive a matched related donor (MRD), a matched unrelated donor (MUD), or cord blood transplant. Researchers also want to learn if these Tregs may prevent or reduce the effects of graft-versus host disease (GVHD). GVHD can result from a reaction of the transplanted cord blood cells against certain tissues in the body. This is an investigational study. Fucosylation of Tregs is not an FDA-approved process. It is currently being used for research purposes only. Fludarabine, melphalan, cyclophosphamide and rituximab are FDA approved and commercially available to be given to patients with leukemia or lymphoma having a cord blood transplant. Total body irradiation is delivered using FDA-approved and commercially available methods. Up to 47 patients will take part in this study. All will be enrolled at MD Anderson.
This Phase 1 clinical study is designed to examine the safety and feasibility of using anti-CD3/CD28 activated marrow infiltrating lymphocytes (MILs) as treatment of relapse after allogeneic hematopoietic cell transplantation (alloHCT) for patients with hematologic malignancies with bone marrow involvement of their relapsed disease. These MILs will be derived from the bone marrow of the relapsed patient who had previously received post-transplantation cyclophosphamide (PTCy) as graft-versus-host disease (GVHD) prophylaxis (PTCy-MILs). A bone marrow aspiration will be performed on the patient to collect \~200ml of marrow for ex vivo expansion. During this expansion process, T cells will be activated and expanded by co-stimulation with anti-CD3/anti-CD28 monoclonal antibodies covalently attached to super-paramagnetic microbeads. Patients will be treated with salvage therapy while this ex vivo expansion is ongoing. After the simultaneous salvage therapy and ex vivo expansion, the activated PTCy-MILs will be reinfused. Patients will be monitored with the primary objective being the feasibility of expanding to targeted dose levels activated PTCy-MILs that do not cause grade III-IV acute GVHD within the first 90 days after PTCy-MIL infusion.
Acute Graft-versus-Host-Disease (GVHD) is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). This study aims to determine if any of three new GVHD prophylaxis approaches improves the rate of GVHD and relapse free survival at one year after transplant compared to the current standard prophylaxis regimen.
The purpose is to determine if the addition of Maraviroc to a standard transplant regimen will reduce the incidence of graft versus host disease in children and young adults after a stem cell transplant.
IL-2 add-back post allogeneic hematopoietic stem cell transplant (HSCT), combined with Sirolimus (SIR), Tacrolimus (TAC) will optimize Treg reconstitution and prevent graft versus host disease (GVHD).
The objective of this study is to determine the maximum tolerated dose (MTD) of bortezomib in combination with calcineurin inhibitor and methotrexate as acute graft versus host disease (aGVHD) prophylaxis in pediatric patients undergoing allogeniec hematopoietic stem cell transplant (alloHSCT)
The purpose of this study is to determine if Bortezomib, known commercially as Velcade is safe and tolerated at different dose levels (amounts) with high dose Cyclophosphamide to be used as graft versus host disease prevention after reduced-intensity allogeneic hematopoietic stem cell transplantation.
Bone marrow transplantation (BMT) is used to successfully treat high-risk forms of leukemia, lymphoma, and other childhood cancers that were once considered incurable. A major barrier to the application of this life-saving treatment is acute graft-versus-host disease (GVHD) which develops in approximately 30-80% of patients and is a leading cause of death from transplant complications. Current GVHD prevention methods are not very efficacious and lead to unacceptable side effects. Mycophenolate mofetil (MMF), an anti-rejection medication used in solid organ transplants, has shown great promise in BMT recipients. The effectiveness of MMF depends on blood levels of mycophenolic acid (MPA, the active form of MMF). Different patients have been found to have different blood levels of MPA when they are given the same dose of MMF. The purpose of this study is to study a novel method of giving MMF based on its metabolism (pharmacokinetics) to achieve desired blood levels of MPA for prevention of GVHD. Non-invasive ways of monitoring the drug exposure will also be studied. The ultimate goal of this study is to improve approaches to GVHD prevention and improve outcomes of BMT in children.
This randomized phase III trial studies how well graft-vs-host disease (GVHD) prophylaxis works in treating patients with hematologic malignancies undergoing unrelated donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant (PBSCT) 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 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation (TBI) together with fludarabine phosphate (FLU), cyclosporine (CSP), mycophenolate mofetil (MMF), or sirolimus before transplant may stop this from happening.
A continuation study of sirolimus and mycophenolate mofetil (MMF) for graft-vs-host disease (GvHD) prophylaxis for patients undergoing matched related allogeneic hematopoietic stem cell transplantation (HSCT) for acute and chronic leukemia, myelodysplastic syndrome (MDS), high risk non-Hodgkin lymphoma (NHL), or Hodgkin lymphoma (HL)
The purpose of the study is to determine if participants who receive the GVHD prophylaxis medication pentostatin will have less severe hepatic toxicities than those receiving MTX. The study is estimated to have sufficient statistical power to ascertain at least a 20% improvement in day 42 NCI CTC grade 2 or above hepatic toxicity-free survival in pentostatin recipients.
This Phase II clinical trial was designed for patients with hematologic malignancies in need of donor peripheral blood stem cell transplant, and have no HLA matched donor. Therefore It will test the efficacy of combining sirolimus, tacrolimus, antithymocyte globulin, and rituximab in preventing graft versus host disease in transplants from HLA Haploidentical and partially mismatched donors.
This trial is comparing whether using a drug called sirolimus for graft versus host disease (GVHD) prevention can decrease the chance of the participant's lymphoma relapsing after transplantation, compared to using a standard GVHD prevention regimen without sirolimus. Since mTOR inhibitors have anti-lymphoma activity, their use after transplantation may lead to a decreased risk of relapse and hence better transplantation outcome.
The purpose of this research is to compare the effectiveness of Tacrolimus and Rapamycin to Tacrolimus and Methotrexate in the prevention of severe graft-versus-host-disease. Graft-versus-host-disease (GVHD) is a risk associated with allogeneic hematopoietic cell transplants (HCT). An allogeneic hematopoietic cell transplant is a transplant using bone marrow and blood cells that come from someone other than the patient (a donor).
The purpose of this study is determine the highest dose of bortezomib, a new drug for graft-versus host disease prevention, that can be given in combination with sirolimus and Tacrolimus, without causing severe side effects. This research is being done because there is no treatment that is 100% effective in preventing graft versus host disease. The goals of this study are to: 1. Collect peripheral blood stem cells (PBSCs) from donors for transplant. 2. Determine the largest possible dose of bortezomib that can be given to recipients with various blood cancers in a safe manner. 3. Monitor the recipient for risk of infection or side affects associated with the transplant. 4. Monitor the recipient for increased immunity following transplantation.
This research study investigates the benefits and possible risks of adding both etanercept (Enbrel) and ECP (extracorporeal photopheresis) to the conventional preventative (or prophylactic) treatments for graft-versus-host disease (GVHD). GVHD is a common, serious, and too often fatal, complication after matched unrelated donor stem cell transplantation, regardless of the pre-transplant conditioning regimen used (full or reduced intensity). Reduced intensity transplants which employ lower doses of chemotherapy during the conditioning phase of the transplant, are less toxic than full intensity transplants. Reduced intensity transplants may extend the unrelated donor transplant option to older patients or to patients with existing medical conditions or illness, where a full intensity transplant is not possible. To be successful, reduced intensity transplants need to offset any lower effectiveness in killing cancer cells during the conditioning phase, with the establishment of a donor cell, graft-versus-leukemia effect (GVL). The GVL effect and GVHD are associated with each other and therefore, the goal of GVHD prophylaxis for this study is not so much to prevent all GVHD, but rather to prevent serious and fatal acute GVHD. Most GVHD-related deaths are either the direct consequence of severe GVHD or from infections associated with intense immunosuppression, a consequence of the standard treatments for acute GVHD, which almost always include high-dose steroids. A more effective prophylaxis therapy that allows for the GVL effect to develop, while limiting the exposure to high-dose steroids may reduce transplant mortality and morbidity. We also will study how key chemical and cellular factors relate to clinical outcome.
RATIONALE: Giving chemotherapy and total-body irradiation 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 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: To look at the ability of umbilical cord blood cells from one or two unrelated donors to serve as a source of stem cells for people needing a bone marrow transplant.
