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

The present project aims at evaluating the capacity of MSC to improve one-year overall survival of patients transplanted with HLA-mismatched PBSC from related or unrelated donors after non-myeloablative conditioning. Co-infusion of MSC has been shown to facilitate engraftment of hematopoietic stem cell (HSC) in an immunodeficient mouse model. In addition, it has been shown that infusion of third party MSC in HSC transplantation could be successfully used as treatment for grade II-IV steroid-refractory acute graft versus host disease. One hundred and twenty patients with HLA-mismatched donors will be included over 6 years at multiple centers across Belgium through the transplant committee of the Belgian Hematological Society. The conditioning regimen will consist of fludarabine and 2 Gy TBI, followed by the infusion of donor HSC. Patients will be randomized 1/1 in double-blind fashion to receive or not MSC (1.5-.3.0 x106/kg) from third-party (either haploidentical family members or unrelated volunteer) donors on day 0. Postgrafting immunosuppression will combine tacrolimus and MMF. Except for the collection, expansion and infusion of MSC, the clinical management of the patient will not differ from that of routine NM-HCT.

The purpose of this study is to evaluate the multi-lineage hematopoietic chimerism for unrelated umbilical cord blood (UCB) grafts pooled from two to three cord blood units. Also to evaluate the toxicity, and antitumor responses of pooled unrelated UCB transplants.

Escalating doses of Omega 3 Fatty Acids are being used in patients who have early stage Chronic Lymphocytic Leukemia (ES-CLL), Monoclonal Gammopathy of Undetermined Significance (MGUS), or Smoldering Multiple Myeloma (SMM), whose disease does not currently require treatment. The primary aim of the study is to determine if the Omega 3 supplementation will help prevent or delay progression of the disease to a stage that requires treatment.

A Notch signalling pathway inhibitor study in pediatric and adult patients with relapsed (worsening) or refractory (not responding to treatment) T-cell acute lymphoblastic leukemia/lymphoma (T-ALL).

Recent data have shown that the inadequate vitamin D status plays a role in the manifestation of the haematologic tumors and serum vitamin D level has a prognostic role also as it determines the tumor mortality. But data have not proved a causal relationship between the inadequate vitamin D status and the unfavourable outcomes so far. It is also still unknown, whether the normalization of vitamin D status in patient with vitamin D inadequacy is able to improve the prognosis and survival. In this study the investigators examine the role of the adequate vitamin D substitution in the improvement of the outcomes of haematologic disorders.

This is a randomized (1:1), open-label, multicenter, active-controlled study in patients with previously treated CD23+ and CD20+ relapsed CLL. Patients will receive treatment with either lumiliximab in combination with FCR or FCR alone.

This study explores the potential to improve the quality of response obtained after induction treatment in Chronic Lymphocytic Leukemia (CLL), by giving a short and intense consolidation schema using high-dose rituximab. Patients in suboptimal response (Minimal Residual Disease persistence) after induction will be selected, as well as those who have a Minimal Residual Disease (MRD) relapse after having achieved MRD negativity.

The purpose of this study is to develop a standard of care treatment using allogeneic stem cells for patients with cancers of the blood. The protocol was revised to reflect that this study is considered "treatment guidelines", rather than a research study.

This clinical trial studies the effect of short-term (acute) and long-term (chronic) exercise on immune characteristics and function (phenotype) of patients with chronic lymphocytic leukemia (CLL). Most newly-diagnosed CLL patients have early-stage disease at the time of diagnosis and do not require treatment. Despite not needing therapy, these patients have significant immune dysfunction. This may lead to an increased risk of serious infections requiring hospitalization and an increased risk of secondary non-blood-based (hematologic) cancers. Increasing CLL patients overall physical fitness levels, through exercise during the observation stage, may provide a realistic approach means to increase survival, decrease treatment-related side effects, and improve immune function. Information learned from this study may help researchers determine whether a particular exercise regimen can be used to strengthen the immune system of CLL patients, delay time to disease progression, assess the need for treatment, and assess infection rates.

This is a phase 1/1b, interventional single arm, open label, treatment study designed to evaluate the safety and feasibility of infusion of autologous T cells engineered to contain an anti-cluster of differentiation 19 (CD19) and anti-cluster of differentiation 20 (CD20) single chain variable fragment (scFv) coupled to cluster of differentiation CD3ζ (CD3ζ) and co-stimulatory domain 4-1BB (4-1BB) signaling domains in patients with relapsed and/or refractory CD19 or CD20 positive B cell malignancies
