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

This phase I trial studies the side effects and best dose of rivogenlecleucel, and how well it works, in treating patients with blood cancer that has come back (recurrent) after stem cell transplant. Donor T-cell therapy (rivogenlecleucel) may help control transplant-related infections after stem cell transplant.

To determine the recommended phase 2 dose (RP2D) of idelalisib and venetoclax in combination with rituximab in patients with relapsed or refractory Chronic lymphocytic leukemia/ Small lymphocytic lymphoma (CLL/SLL) following a lead-in period with idelalisib and rituximab

This study evaluates the effectiveness of acalabrutinib treatment in patients with chronic lymphocytic leukemia (CLL) deemed at high risk for Richter's Transformation (RT). This is a single arm study. Enrolled patients will initiate therapy with acalabrutinib and will dose continuously. While on study, subjects will be monitored monthly for the first 3 months, then every three months thereafter until disease progression, discontinuation due to toxicity, death, or study completion.

This Phase I, multiple ascending dose study will seek to enroll subjects with relapsed/refractory Chronic B-cell Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL) with confirmed and measurable disease who have received standard treatment with at least one anti-CD20 antibody (e.g.; rituximab, ofatumumab) containing front-line regimen that resulted in initial response, followed by relapse/recurrence and who are not eligible for any further approved biologic therapy, chemotherapy and/or autologous stem transplantation and/or refuse alternative approved therapies and/or are unlikely to achieve clinical benefit from any therapy of higher priority by Investigator assessment.

This phase II trial studies how well ibrutinib or idelalisib works in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma that is persistent or has returned (relapsed) after donor stem cell transplant. Ibrutinib and idelalisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The goal of this clinical research study is to learn if urelumab given in combination with rituximab can help to control CLL or SLL. The safety of the drug combination will also be studied.

This phase I/II trial studies the side effects and best dose of romidepsin and lenalidomide when combined with rituximab and to see how well this combination works in treating patients with B-cell non-Hodgkin lymphoma that has returned (recurrent) or did not respond to treatment (refractory). Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Romidepsin and lenalidomide may stop the growth of cancer cells by blocking enzymes needed for cell growth. Giving rituximab together with romidepsin and lenalidomide may be a better treatment for B-cell non-Hodgkin lymphoma.

This study will determine the safety and applicability of experimental forms of umbilical cord blood (UCB) transplantation for patients with high risk hematologic malignancies who might benefit from a hematopoietic stem cell transplant (HSCT) but who do not have a standard donor option (no available HLA-matched related donor (MRD), HLA-matched unrelated donor (MUD)), or single UCB unit with adequate cell number and HLA-match).

Background: - Stem cell transplantation from a partially matched donor can lead to graft-versus-host disease (GVHD). Researchers want to learn how to improve these transplantations. Objective: - To see if very low doses of Interleukin-2 after a partially matched transplantation prevent GVHD. Eligibility: Recipients: age 18 65, with certain bone marrow or lymphatic system diseases and an available family member with partial tissue match. Donors: age 18 80. Design: Recipients will be screened with medical history, physical exam, and many tests including blood and tissue tying. Donors will be screened with medical history, physical exam, blood tests and tissue typing. Recipients will stay in the hospital 3 6 weeks. All participants will have apheresis. Blood is drawn from one arm, run through a machine that collects white blood cells, then returned into the other arm. Recipients will have: Intravenous (IV) line placed under the skin and into a neck vein, to stay throughout transplant and recovery. They may also have a catheter inserted for collecting immune cells. Bone marrow sample taken by needle. They will have 3 more after transplant. Donors will have: Filgrastim injected once daily for 5 6 days. Stem and immune cells collected by another apheresis. Recipients will get: Eight 30-minute doses of radiation, sitting at a machine. Donor immune cells by IV, 6 days before the transplant day. Chemotherapy drugs by IV. <TAB><TAB>- Donor stem cells by IV on transplant day. After transplant, recipients will give self-injections of very low doses of Interleukin-2 once daily for about 12 weeks. Before and after transplant, recipients will get medicine to suppress the immune system and antibiotics to prevent infections Recipients must stay near NIH for 3 6 months after transplant. All recipients and donors will have 3 years of follow-up.

This phase II trial studies how well donor atorvastatin treatment works in preventing severe graft-versus-host disease (GVHD) after nonmyeloablative peripheral blood stem cell (PBSC) transplant in patients with hematological malignancies. Giving low doses of chemotherapy, such as fludarabine phosphate, before a donor PBSC transplantation slows the growth of cancer cells and may also prevent the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also cause an immune response against the body's normal cells (GVHD). Giving atorvastatin to the donor before transplant may prevent severe GVHD.
