Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

This is a Phase II study of allogeneic hematopoietic stem cell transplant (HCT) using a myeloablative preparative regimen (of either total body irradiation (TBI); or, fludarabine/busulfan for patients unable to receive further radiation). followed by a post-transplant graft-versus-host disease (GVHD) prophylaxis regimen of post-transplant cyclophosphamide (PTCy), tacrolimus (Tac), and mycophenolate mofetil (MMF).

The purpose of the study is to find out if an investigational drug called PRGN-3007 UltraCAR-T cells (PRGN-3007 T cells) can help people with ROR1-positive hematologic chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma (DLBCL) and solid tumor triple negative breast cancer (TNBC) malignancies.

This is a treatment guideline for an unrelated umbilical cord blood transplant (UCBT) using a myeloablative preparative regimen for the treatment of hematological diseases, including, but not limited to acute leukemias. The myeloablative preparative regimen will consist of cyclophosphamide (CY), fludarabine (FLU) and fractionated total body irradiation (TBI).

The primary purpose of the study is to evaluate whether weekly administered XEMBIFY® plus Standard Medical Treatment (SMT) over a one-year period will reduce the rate of major bacterial infections per participant per year in participants with hypogammaglobulinemia (HGG) associated with B-cell chronic lymphocytic leukemia (CLL) in comparison to the Placebo plus SMT group.

The purpose of this study is to determine the rate of minimum residual disease (MRD) negative response (i.e. the rate of no evidence of disease) of the study drugs, zanubrutinib, obinutuzumab, and venetoclax, given in combination as a treatment for CLL and/or SLL.

This study will find out whether people with CLL or SLL who have received treatment with venetoclax, either alone or in combination with another drug, and who are found to be MRD-negative, can stop treatment with venetoclax and remain off-treatment for 12 months or more. The researchers will also see whether study participants remain MRD-negative after they stop treatment with venetoclax.

This randomized phase II trial includes a blood stem cell transplant from an unrelated donor to treat blood cancer. The treatment also includes chemotherapy drugs, but in lower doses than conventional (standard) stem cell transplants. The researchers will compare two different drug combinations used to reduce the risk of a common but serious complication called "graft versus host disease" (GVHD) following the transplant. Two drugs, cyclosporine (CSP) and sirolimus (SIR), will be combined with either mycophenolate mofetil (MMF) or post-transplant cyclophosphamide (PTCy). This part of the transplant procedure is the main research focus of the study.

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

This phase II trial compares the effect of initial vaccination (PCV13 followed by PSV23) with yearly vaccinations of PSV23 to the standard 5 year vaccination in patients with chronic lymphocytic leukemia. At present chronic lymphocytic leukemia patients are poorly protected by anti-pneumococcal vaccination. Current vaccination schedule for chronic lymphocytic leukemia patients is based on general recommendations in immunocompromised patients (initial vaccination with PCV13 followed by one dose of PSV23 after an interval of two months, followed by revaccination at 5 years). Giving patients frequent immunization as compared to 5 year immunization may result in higher protective titers in patients.

The purpose of this study is to collect long-term safety and efficacy data for participants treated with ibrutinib and to provide ongoing access to ibrutinib for participants who are currently enrolled in ibrutinib studies that have been completed according to the parent protocol, are actively receiving treatment with ibrutinib, and who continue to benefit from ibrutinib treatment.
