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

RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. PURPOSE: This phase II trial is studying the side effects and how well alemtuzumab works in treating patients with B-cell chronic lymphocytic leukemia in partial remission or complete remission.

We would like patients to be in a research study to determine the safety and effectiveness of special cells that may make their own immune system fight their cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help their immune system kill cancer cells. Additionally, we will stimulate the cancer cells with normal embryonic fibroblasts (cells that develop into normal connective tissues in the body) so that they will make another natural protein called CD40 ligand (CD40L). Studies of cancers in animals suggest IL-2 performs better when mixed with CD40L. Some of these cells will then be put back into the patients body with the goal that they will act like a vaccine and stimulate their immune system to attack the CLL cells. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L with cancer cells help the body recognize and kill cancer cells. We have already conducted a study similar to this in patients with CLL. In that study, the subjects received about three months of injections (shots). In those subjects we saw some changes in the subject's immune system that might indicate that the modified cells were helping their immune system fight the cancer. However, in most of the subjects this change in the immune system went away after the injections were stopped. In this study we want to see if we can make the change in the immune system last longer by giving more injections over a longer period of time. We hope that this might produce a better response directed at the CLL cells. We will also be looking at the effect on cells called cancer stem cells which grow into the CLL cells we see in the blood. Specifically, this study will allow subjects to receive the injections for up to one year.

This is a two-cohort, multicenter, open-label study of tafasitamab (MOR208) combined with idelalisib or venetoclax in adult patients with R/R CLL or R/R SLL pretreated with a BTK inhibitor (e.g., ibrutinib) as single agent or as part of combination therapy. Patients completing the study treatment are invited to participate in an optional biomarker sub-study.

This is a Phase 1, Open-Label, Adaptive Study of Novel GS-9973 Tablet Formulations to Evaluate the Effect of Acid Reducing Agents, Relative Bioavailability, and Food Effect on GS-9973 Pharmacokinetics.

This is a trial in patients with previously untreated CLL. Eligible patients will receive Lenalidomide with a backbone of Fludarabine and Rituximab for 6 therapy cycles. Lenalidomide will be increased by dose steps of 5 mg every cycle in the absence of limiting toxicity. If limiting toxicity ensues the patients will be treated with last tolerable dose for the remainder of the 6 treatment cycles. The first 5 patients will start with dose level 5 mg Lenalidomide and further escalating dose. After the fifth patient is included in the study, enrolment will be interrupted until this patient has finished his first treatment cycle. A safety board will evaluate the toxicities of the first 5 patients. If there are more than 2 patients experiencing a dose limiting toxicity (DLT) in the first treatment cycle, the starting dose will not be escalated and further 5 patients will be enrolled with a starting dose of 5 mg Lenalidomide. If only 2 or less patients experience a DLT in the first treatment cycle, the next 5 patients will start the treatment with 10 mg Lenalidomide. The rational for the higher starting doses stems from the lack of tumor lysis or tumor flare toxicity in this combination on the one hand and from the observation that the very slow escalation from 2,5 mg on led to a lack of efficacy in monotherapy trials due to early progression in a relevant number of cases. The increase of the Lenalidomide dosage should result in an increased efficacy especially at the beginning and a higher cumulative dose of Lenalidomide. The identification of patients intolerant to Lenalidomide by immunophenotyping of the T cells for validation is also part of this trial, because intolerance seems to be not dose dependent but may be caused by T cell activation. Therefore, early identification of patients intolerant to this form of modern immunochemotherapy and establishing efficient Lenalidomide based combination therapy is an important part of improvement of current CLL treatment.

An Open-label Extension Study in Patients 65 Years or Older with Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL) Who Participated in Study PCYC-1115-CA (Ibrutinib versus Chlorambucil)

This phase II trial studies the efficacy (activity), and tolerability of curcumin and cholecalciferol combination in treating patients with previously untreated stage 0-II chronic lymphocytic leukemia or small lymphocytic lymphoma. Curcumin and cholecalciferol may prevent or slow the growth of cancer cells.

The purpose of this study is to evaluate the safety and effectiveness of TGR-1202 in combination with obinutuzumab (Gazyva) and chlorambucil in patients with chronic lymphocytic leukemia.

This open-label, randomized, 3-arm study will evaluate the efficacy and safety of (obinutuzumab) RO5072759 in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000 mg intravenous (iv) infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.

A Phase 3 (extension) clinical trial to examine the efficacy of IPI-145 (duvelisib) monotherapy or ofatumumab monotherapy in participants with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who experienced disease progression after treatment with IPI-145 or ofatumumab in study IPI-145-07 (NCT02004522).
